Infiniti Qx (2009 year). Instruction

CAUTION

Automatic transmission models cannot

be push-started or tow-started. Attempt-

ing to do so may cause transmission

damage.

WARNING

● Do not continue to drive if your vehicle

overheats. Doing so could cause engine

damage or a vehicle fire.

● To avoid the danger of being scalded,

never remove the radiator or coolant

reservoir cap while the engine is still

hot. When the radiator or coolant reser-

voir cap is removed, pressurized hot

water will spurt out, possibly causing

serious injury.

● Do not open the hood if steam is com-

ing out.

If your vehicle is overheating (indicated by an

extremely high temperature gauge reading and

the illumination of the engine oil pressure/engine

coolant temperature high indicator light), or if you

feel a lack of engine power, detect abnormal

noise, etc. take the following steps.

1. Move the vehicle safely off the road, apply

the parking brake and move the shift lever to

P (Park).
Do not stop the engine.

2. Turn off the air conditioner. Open all the

windows, move the heater or air conditioner

temperature control to maximum hot and fan

control to high speed.

3. Get out of the vehicle. Look and listen for

steam or coolant escaping from the radiator

before opening the hood. (If steam or cool-

ant is escaping, turn off the engine.) Do not

open the hood further until no steam or

coolant can be seen.

4. Open the engine hood.

WARNING

If steam or water is coming from the en-

gine, stand clear to prevent getting

burned.

5. Visually check drive belts for damage or

looseness. Also check if the cooling fan is

running. The radiator hoses and radiator

should not leak water. If coolant is leaking,

the water pump belt is missing or loose, or

the cooling fan does not run, stop the en-

gine.

WARNING

Be careful not to allow your hands, hair,

jewelry or clothing to come into contact

with, or get caught in, engine belts or the

engine cooling fan. The engine cooling

fan can start at any time.

ant level in the engine coolant reservoir tank

with the engine running. Add coolant to the

engine coolant reservoir tank if necessary.

Have your vehicle repaired at an INFINITI

dealer.

When towing your vehicle, all State (Provincial in

Canada) and local regulations for towing must be

followed. Incorrect towing equipment could dam-

age your vehicle. Towing instructions are avail-

able from an INFINITI dealer. Local service opera-

tors are generally familiar with the applicable laws

and procedures for towing. To assure proper

towing and to prevent accidental damage to your

vehicle, INFINITI recommends having a service

operator tow your vehicle. It is advisable to have

the service operator carefully read the following

precautions:

WARNING

● Never ride in a vehicle that is being

towed.

● Never get under your vehicle after it has

been lifted by a tow truck.

CAUTION

● When towing, make sure that the trans-

mission, axles, steering system and

powertrain are in working condition. If

any unit is damaged, dollies must be

used.

● Always attach safety chains before

towing.

result in serious injury. Parts of your

vehicle could also overheat and be

damaged.

CAUTION

● Tow chains or cables must be attached

only to the main structural members of

the vehicle or the towing hooks (if so

equipped). Otherwise, the vehicle body

will be damaged.

● Use the towing hook (if so equipped)

only to free a vehicle stuck in sand,

snow, mud, etc. Never tow the vehicle

for a long distance using only the tow-

ing hook.

● The towing hook is under tremendous

force when used to free a stuck vehicle.

Never pull the hook at an angle.

● Always pull the cable straight out from

the front or rear of the vehicle.

● Pulling devices should be routed so

they do not touch any part of the sus-

pension, steering, brake or cooling

systems.

If your vehicle is stuck in sand, snow, mud, etc.,

use the following procedure:

1. Turn off the Vehicle Dynamic Control System

(if so equipped).

2. Make sure the area in front and behind the

vehicle is clear of obstructions.

3. Turn the steering wheel right and left to clear

an area around the front tires.

4. Slowly rock the vehicle forward and back-

ward.
● Shift back and forth between R (Reverse)

and D (Drive).

● Apply the accelerator as little as possible

to maintain the rocking motion.

● Release the accelerator pedal before

shifting between R and D.

● Do not spin the tires above 35 MPH

(55 km/h).

5. If the vehicle cannot be freed after a few

tries, contact a professional towing service

In order to maintain the appearance of your ve-

hicle, it is important to take proper care of it.
To protect the paint surfaces, please wash your

vehicle as soon as you can:

● after a rainfall to prevent possible damage

from acid rain.

● after driving on coastal roads.
● when contaminants such as soot, bird drop-

pings, tree sap, metal particles or bugs get

on the paint surface.

● when dust or mud builds up on the surface.

Whenever possible, store or park your vehicle

inside a garage or in a covered area.
When it is necessary to park outside, park in a

shady area or protect the vehicle with a body

cover.
Be careful not to scratch the paint surface
when putting on or removing the body
cover.

WASHING

Wash dirt off with a wet sponge and plenty of

water. Clean the vehicle thoroughly using a mild

soap, a special vehicle soap or general purpose

dishwashing liquid mixed with clean, lukewarm

(never hot) water.

CAUTION

● Do not use car washes that use acid in

the detergent. Some car washes, espe-

cially brushless ones, use some acid for

cleaning. The acid may react with some

plastic vehicle components, causing

them to crack. This could affect their

appearance, and also could cause them

not to function properly. Always check

with your car wash to confirm that acid

is not used.

● Do not wash the vehicle with strong

household soap, strong chemical deter-

gents, gasoline or solvents.

● Do not wash the vehicle in direct sun-

light or while the vehicle body is hot, as

the surface may become water-spotted.

● Avoid using tight-napped or rough

cloths, such as washing mitts. Care

must

taken

when

removing

caked-on dirt or other foreign sub-

stances so the paint surface is not

scratched or damaged.

Rinse the vehicle thoroughly with plenty of clean

water.
Inside flanges, seams and folds on the doors,

hatches and hood are particularly vulnerable to

the effects of road salt. Therefore, these areas

must be cleaned regularly. Take care that the

drain holes in the lower edge of the door are

open. Spray water under the body and in the

wheel wells to loosen the dirt and wash away

road salt.
A damp chamois can be used to dry the vehicle to

avoid water spots.

WAXING

Regular waxing protects the paint surface and

helps retain new vehicle appearance. Polishing is

recommended to remove built-up wax residue

and to avoid a weathered appearance before

re-applying wax.
An INFINITI dealer can assist you in choosing the

proper product.

● Wax your vehicle only after a thorough wash-

ing. Follow the instructions supplied with the

wax.

● Do not use a wax containing any abrasives,

cutting compounds or cleaners that may

damage the vehicle finish.

Machine compounding or aggressive polishing

on a base coat/clear coat paint finish may dull the

finish or leave swirl marks.

REMOVING SPOTS

Remove tar and oil spots, industrial dust, insects,

and tree sap as quickly as possible from the

surface of the paint to avoid lasting damage or

staining. Special cleaning products are available

at an INFINITI dealer or any automotive accessory

store.

UNDERBODY

In areas where road salt is used in winter, it is

necessary to clean the underbody regularly in

order to prevent dirt and salt from building up and

causing the acceleration of corrosion on the un-

derbody and suspension. Before the winter pe-

riod and again in the spring, the underseal must

be checked and, if necessary, retreated.

GLASS

Use glass cleaner to remove smoke and dust film

from the glass surfaces. It is normal for glass to

become coated with a film after the vehicle is

parked in the hot sun. Glass cleaner and a soft

cloth will easily remove this film.

CAUTION

When cleaning the inside of the windows,

do not use sharp-edged tools, abrasive

cleaners or chlorine-based disinfectant

cleaners. They could damage the electri-

cal conductors, radio antenna elements or

rear window defroster elements.

ALUMINUM ALLOY WHEELS

Wash the wheels regularly with a sponge damp-

ened in a mild soap solution, especially during

winter months in areas where road salt is used. If

not removed, road salt can discolor the wheels.

CAUTION

Follow the directions below to avoid

staining or discoloring the wheels:
● Do not use a cleaner that uses strong

acid or alkali contents to clean the

wheels.

● Do not apply wheel cleaners to the

wheels when they are hot. The wheel

temperature should be the same as am-

bient temperature.

● Rinse the wheel to completely remove

the cleaner within 15 minutes after the

cleaner is applied.

CHROME PARTS

Clean all chrome parts regularly with a non-

abrasive chrome polish to maintain the finish.

TIRE DRESSINGS

INFINITI does not recommend the use of tire

dressings. Tire manufacturers apply a coating to

the tires to help reduce discoloration of the rub-

ber. If a tire dressing is applied to the tires, it may

react with the coating and form a compound. This

compound may come off the tire while driving and

stain the vehicle paint.
If you choose to use a tire dressing, take the

following precautions:

● Use a water-based tire dressing. The coat-

ing on the tire dissolves more easily with an

oil-based tire dressing.

● Apply a light coat of tire dressing to help

prevent it from entering the tire tread/

grooves (where it would be difficult to re-

move).

● Wipe off excess tire dressing using a dry

towel. Make sure the tire dressing is com-

pletely removed from the tire tread/grooves.

● Allow the tire dressing to dry as recom-

mended by tire dressing manufacturer.

Occasionally remove loose dust from the interior

trim, plastic parts and seats using a vacuum

cleaner or soft bristled brush. Wipe the vinyl and

leather surfaces with a clean, soft cloth damp-

ened in mild soap solution, then wipe clean with a

dry, soft cloth.
Regular care and cleaning is required in order to

maintain the appearance of the leather.
Before using any fabric protector, read the manu-

facturer’s recommendations. Some fabric pro-

tectors contain chemicals that may stain or

bleach the seat material.
Use a cloth dampened only with water to clean

the meter and gauge lens.

WARNING

Do not use water or acidic cleaners (hot

steam cleaners) on the seat. This can

damage the seat or occupant classifica-

tion sensor. This can also affect the opera-

tion of the air bag system and result in

serious personal injury.

CAUTION

● Never use benzine, thinner or any simi-

lar material.

● Small dirt particles can be abrasive and

damaging to leather surfaces and

should be removed promptly. Do not

use saddle soap, car waxes, polishes,

oils, cleaning fluids, solvents, deter-

gents or ammonia-based cleaners as

they may damage the leather’s natural

finish.

● Never use fabric protectors unless rec-

ommended by the manufacturer.

● Do not use glass or plastic cleaner on

meter or gauge lens covers. It may dam-

age the lens cover.

FLOOR MATS

The use of genuine INFINITI floor mats can ex-

tend the life of your vehicle carpet and make it

easier to clean the interior. No matter what

mats are used, be sure they are fitted for

your vehicle and are properly positioned in

the footwell to prevent interference with

pedal operation. Mats should be maintained

with regular cleaning and replaced if they be-

come excessively worn.

Floor mat positioning aid

This vehicle includes two driver’s side front floor

mat brackets and one passenger’s side front floor

mat bracket to help keep your floor mats in place.

INFINITI floor mats have been specially designed

for your vehicle model. The driver’s side floor mat

has two grommet holes incorporated in it and the

passenger’s side has one grommet hole. Position

each mat by placing the floor mat bracket hook

through the floor mat grommet holes while cen-

tering the mat in the footwell.
Periodically check to make certain the mats are

properly positioned.

SEAT BELTS

The seat belts can be cleaned by wiping them

with a sponge dampened in a mild soap solution.

Allow the belts to dry completely in the shade

before using them. See “Seat belt maintenance”

in the “Safety – Seats, seat belts and supplemen-

tal restraint system” section of this instruction.

WARNING

Do not allow wet seat belts to roll up in the

retractor. NEVER use bleach, dye or

chemical solvents to clean the seat belts,

since these materials may severely

weaken the seat belt webbing.

MOST COMMON FACTORS

CONTRIBUTING TO VEHICLE

CORROSION

● The accumulation of moisture-retaining dirt

and debris in body panel sections, cavities,

and other areas.

● Damage to paint and other protective coat-

ings caused by gravel and stone chips or

minor traffic accidents.

ENVIRONMENTAL FACTORS

INFLUENCE THE RATE OF

CORROSION
Moisture

Accumulation of sand, dirt and water on the ve-

hicle body underside can accelerate corrosion.

Wet floor coverings will not dry completely inside

the vehicle, and should be removed for drying to

avoid floor panel corrosion.

Relative humidity

Corrosion will be accelerated in areas of high

relative humidity, especially those areas where

the temperatures stay above freezing and where

atmospheric pollution exists and road salt is

used.

Temperature

High temperatures accelerate the rate of corro-

sion to those parts which are not well ventilated.

Air pollution

Industrial pollution, the presence of salt in the air

in coastal areas, or heavy road salt use acceler-

ates the corrosion process. Road salt also accel-

erates the disintegration of paint surfaces.

TO PROTECT YOUR VEHICLE

FROM CORROSION

● Wash and wax your vehicle often to keep the

vehicle clean.

● Always check for minor damage to the paint

and repair it as soon as possible.

● Keep drain holes at the bottom of the doors

open to avoid water accumulation.

● Check the underbody for accumulation of

sand, dirt or salt. If present, wash with water

as soon as possible.

CAUTION

● NEVER remove dirt, sand or other de-

bris from the passenger compartment

by washing it out with a hose. Remove

dirt with a vacuum cleaner or broom.

● Never allow water or other liquids to

come in contact with electronic compo-

nents inside the vehicle as this may

damage them.

Chemicals used for road surface de-icing are

extremely corrosive. They accelerate corrosion

and deterioration of underbody components

such as the exhaust system, fuel and brake lines,

brake cables, floor pan and fenders.
In winter, the underbody must be cleaned

periodically.
For additional protection against rust and corro-

sion, which may be required in some areas, con-

Your new INFINITI has been designed to have

minimum maintenance requirements with long

service intervals to save you both time and

money. However, some day-to-day and regular

maintenance is essential to maintain your INFINI-

TI’s good mechanical condition, as well as its

emission and engine performance.
It is the owner’s responsibility to make sure that

the scheduled maintenance, as well as general

maintenance, is performed.
As the vehicle owner, you are the only one who

can ensure that your vehicle receives proper

maintenance. You are a vital link in the mainte-

nance chain.
Scheduled maintenance

For your convenience, both required and optional

scheduled maintenance items are described and

listed in your “INFINITI Service and Maintenance

Guide”. You must refer to that guide to ensure

that necessary maintenance is performed on your

INFINITI at regular intervals.
General maintenance

General maintenance includes those items which

should be checked during normal day-to-day op-

eration. They are essential for proper vehicle op-

eration. It is your responsibility to perform these

maintenance procedures regularly as prescribed.

Performing general maintenance checks requires

minimal mechanical skill and only a few general

automotive tools.
These checks or inspections can be done by you,

a qualified technician, or, if you prefer, an INFINITI

dealer.
Where to go for service
If maintenance service is required or your vehicle

appears to malfunction, have the systems

checked and corrected by an INFINITI dealer.
INFINITI technicians are well-trained specialists

who are kept up-to-date with the latest service

information through technical bulletins, service

tips, and in-dealership training programs. They

are completely qualified to work on INFINITI ve-

hicles before they work on your vehicle, rather

than after they have worked on it.
You can be confident that an INFINITI dealer’s

service department performs the best job to meet

the maintenance requirements on your vehicle —

in a reliable and economical way.

During the normal day-to-day operation of the

vehicle, general maintenance should be per-

formed regularly as prescribed in this section. If

you detect any unusual sounds, vibrations or

smells, be sure to check for the cause or have an

INFINITI dealer do it promptly. In addition, you

should notify an INFINITI dealer if you think that

repairs are required.
When performing any checks or maintenance

work, closely observe the “Maintenance precau-

tions” later in this section.

EXPLANATION OF GENERAL

MAINTENANCE ITEMS

Additional information on the following

transmitter grommet seal, valve core and cap

when the tires are replaced due to wear or age.
Wheel alignment and balance If the vehicle

should pull to either side while driving on a

straight and level road, or if you detect uneven or

abnormal tire wear, there may be a need for wheel

alignment. If the steering wheel or seat vibrates at

normal highway speeds, wheel balancing may be

needed.

● For additional information regarding tires,

refer to “Important Tire Safety Information”

(US) or “Tire Safety Information” (Canada) in

the Warranty Information Booklet .

The maintenance items listed here should be

checked periodically (for example, each time you

check the engine oil or refuel).
Battery* Check the fluid level in each cell. It

should be between the MAX and MIN lines. Ve-

hicles operated in high temperatures or under

severe conditions require frequent checks of the

battery fluid level.
Brake fluid level* Make sure that the brake fluid

level is between the MIN and MAX lines on the

reservoir.

Engine coolant level* Check the coolant level

when the engine is cold.
Engine drive belts* Make sure the drive belts

are not frayed, worn, cracked or oily.
Engine oil level* Check the level after parking

the vehicle on a level surface with the engine off.

Wait more than 10 minutes for the oil to drain

back into the oil pan.
Exhaust system Make sure there are no loose

supports, cracks or holes. If the sound of the

exhaust seems unusual or there is a smell of

exhaust fumes, immediately have the exhaust

system inspected by an INFINITI dealer. See the

carbon monoxide warning in the “Starting and

driving” section of this manual.
Fluid leaks Check under the vehicle for fuel, oil,

water or other fluid leaks after the vehicle has

been parked for a while. Water dripping from the

air conditioner after use is normal. If you should

notice any leaks or if gasoline fumes are evident,

check for the cause and have it corrected imme-

diately.
Power steering fluid level* and lines Check

the level when the fluid is cold, with the engine

off. Check the lines for proper attachment, leaks,

cracks, etc.
Radiator and hoses Check the front of the

radiator and clean off any dirt, insects, leaves,

etc., that may have accumulated. Make sure the

hoses have no cracks, deformation, rot or loose

connections.
Underbody The underbody is frequently ex-

posed to corrosive substances such as those

used on icy roads or to control dust. It is very

important to remove these substances from the

underbody, otherwise rust may form on the floor

pan, frame, fuel lines and exhaust system. At the

end of winter, the underbody should be thor-

oughly flushed with plain water, in those areas

where mud and dirt may have accumulated. See

the “Appearance and care” section of this

manual.

When performing any inspection or maintenance

work on your vehicle, always take care to prevent

serious accidental injury to yourself or damage to

the vehicle. The following are general precau-

tions which should be closely observed.

WARNING

● Park the vehicle on a level surface, ap-

ply the parking brake securely and

block the wheels to prevent the vehicle

from moving. Move the shift selector

lever to P (Park).

● Be sure the ignition key is in the OFF or

LOCK position when performing any

parts replacement or repairs.

● Your vehicle is equipped with an auto-

matic engine cooling fan. It may come

on at any time without warning, even if

the ignition key is in the OFF position

and the engine is not running. To avoid

injury, always disconnect the negative

battery cable before working near the

fan.

● If you must work with the engine run-

ning, keep your hands, clothing, hair

and tools away from moving fans, belts

and any other moving parts.

● It is advisable to secure or remove any

loose clothing and remove any jewelry,

such as rings, watches, etc. before

working on your vehicle.

● Always wear eye protection whenever

you work on your vehicle.

● If you must run the engine in an en-

closed space such as a garage, be sure

there is proper ventilation for exhaust

gases to escape.

● Never get under the vehicle while it is

supported only by a jack. If it is neces-

sary to work under the vehicle, support

it with safety stands.

● Keep smoking materials, flame and

sparks away from the fuel tank and

battery.

● On gasoline engine models, the fuel

filter or fuel lines should be serviced by

an INFINITI dealer because the fuel

lines are under high pressure even

able. See “Owner’s Manual/Service Manual or-
