Low Speed Control

The low-speed function, Low Speed Control
(LSC), facilitates and improves control and trac-
tion on rough roads and slippery surfaces, e.g.
when towing a trailer on grass or up boat ramps.

In vehicles equipped with drive mode button

the function is included in the Off Road drive
mode.

Low Speed Control is designed for driving on
rough roads and when towing trailers at low
speeds, up to approximately 40 km/h (25 mph).

When driving at low speeds, LSC prioritizes low
gears and all-wheel drive to help avoid wheel spin
and improve traction on all wheels. The accelera-
tor pedal will be less responsive to improve trac-
tion and speed control at low speeds.

The function is activated together with Hill
Descent Control (HDC), which makes it possible
to control speed going down steep hills using the
accelerator pedal and reduces the need to use
the brake pedal. The system makes it possible to
maintain a low and uniform speed when driving
down steep hills.

NOTE

When LSC with HDC is activated, the feel of
the accelerator pedal and engine response
will change.

NOTE

This drive mode is not designed to be used
for normal street driving.

NOTE

The function is deactivated when driving at
high speeds and must be reactivated at lower
speeds if so desired.

Hill Descent Control

The function for assisting when driving downhill,
Hill Descent Control (HDC), is a low-speed
function with increased engine braking. The
function makes it possible to increase or
decrease the vehicle's speed on steep downhill
gradients by only using the accelerator pedal,
without applying the brakes.

In vehicles equipped with drive mode button

the function is included in the Off Road drive
mode.

HDC is designed for driving on rough roads at
low speeds and downhill gradients with slippery
or otherwise difficult road surfaces. The driver
does not need to use the brake pedal but can
instead focus on steering.

WARNING

HDC is only intended to be a supplementary

braking aid and it does not function in all sit-

uations.
The driver is always ultimately responsible for

operating the vehicle in a safe manner.

Function

Hill Descent Control allows the vehicle to move
forward or backward at very low speeds assisted
by the brake system. The driver can increase the
speed by pressing the accelerator pedal. When
the accelerator pedal is released, the vehicle will

return to very low speed regardless of how steep
the hill is and without the brakes needing to be
applied. The brake lights will illuminate when the
function is activated.

The driver can brake to stop or slow the vehicle
at any time by depressing the brake pedal.

HDC is activated along with Low Speed Control
(LSC), which facilitates and improves traction and
control on rough and slippery surfaces. The sys-
tem is intended to be used at low speeds, up to
approximately 40 km/h (25 mph).

To keep in mind when using HDC

•

If the function is switched off while driving on
a steep downhill gradient, braking effect will
be gradually reduced.

•

HDC can be used in gear positions D and R,
and in manual gears 1 or 2.

•

It is not possible to manually shift to third
gear or higher when HDC is active.

Economical driving

Drive economically and environmentally con-
scious by thinking ahead, avoiding rapid starts
and stops and adapting driving style and speed
to the current traffic conditions.

Driving economically conserves natural
resources

Observe the following rules:

•

Do not warm up the engine by idling. It is
better to begin driving normally immediately
after starting the engine. A cold engine uses
more fuel than a warm engine and is subject
to increased wear.

•

Whenever possible, avoid using the vehicle to
drive short distances. The engine does not
have time to reach a normal operating tem-
perature and this leads to increased fuel
consumption.

•

Maintain a steady speed and a generous fol-
lowing distance to traffic ahead to minimize
braking.

•

For lower fuel consumption, activate Eco
drive mode.

•

Use the Eco Coast function in drive mode
Eco - engine braking is deactivated, allowing
the vehicle's kinetic energy to be used to roll
greater distances.

•

Use gear D as often as possible and avoid
using the kick-down function.

•

Fuel consumption is increased at high
speeds - air resistance increases with speed.

•

Remove unnecessary items from the vehicle
- the heavier the load, the higher the fuel
consumption.

•

Maintain the correct pressure in the tires and
check pressure regularly.

•

The type of tires used could affect fuel con-
sumption - consult a retailer for advice on
suitable tires.

•

Do not use winter tires after the winter sea-
son has ended.

•

Roof loads increase air resistance and
increase fuel consumption. Remove roof
boxes, ski racks, etc. that are not in use.

•

Avoid driving with the windows open.

•

Using the trip computer's fuel consumption
indicators can help you learn how to drive
more economically.

Other factors that decrease fuel
consumption

•

Dirty air cleaner.

•

Dirty engine oil and clogged oil filter.

•

Incorrect front-end alignment.

•

Incorrect wheel alignment.

Some of the above items and others are checked
as part of Volvo's standard maintenance sched-
ule.

Preparing for a long trip

It is important to have the vehicle's systems and
equipment checked carefully before driving long
distances.

Check that:

•

the engine is running properly and that fuel
consumption is normal

•

there are no leaks (fuel, oil or other fluid)

•

the brake pedal is functioning optimally

•

all lights are working

‒ adjust the headlight

height if the vehicle is carrying a heavy load

•

tire tread depth and air pressure are at cor-
rect levels. Change to snow tires when driv-
ing in areas where there is a risk of snowy or
icy roads.

•

the start battery is sufficiently charged

•

the wiper blades are in good condition

Winter driving

It is important to check the vehicle before driving
in cold/snowy conditions to make sure it can be
driven safely.

Before the cold season arrives:

•

Make sure the engine coolant contains 50%
antifreeze. This mixture helps protect the
engine from frost erosion down to
approx. -35 °C (-31 °F). Do not mix different
types of antifreeze as this could pose a
health risk.

•

Keep the fuel tank well filled to prevent con-
densation from forming.

•

Check the viscosity of the engine oil. Oil with
low viscosity (thinner oil) improves cold-
weather starting and reduces fuel consump-
tion when driving with a cold engine.

CAUTION

Low-viscosity oil should not be used with hard
driving or in hot weather.

•

Check the condition and charge level of the
start battery. Cold weather places greater
demands on the start battery and reduces its
capacity.

•

Use washer fluid containing antifreeze to
help prevent ice from forming in the washer
fluid reservoir.

* Option/accessory.

405

Slippery driving conditions

For optimal traction and roadholding, Volvo rec-
ommends using snow tires on all wheels when-
ever there is a risk of snow or ice on the road.

NOTE

Certain countries require use of winter tires
by law. Not all countries permit the use of
studded tires.

Practice driving on slippery surfaces under con-
trolled conditions to learn how the vehicle reacts.

Driving through standing water

Driving the vehicle through a deep pool of stand-
ing water on a water-covered roadway is called
fording. This must be done with great caution.

The vehicle can be driven through water up to a
depth of 45 cm (17.7 in) at no more than walking
speed. Be particularly careful when driving
through flowing water.

When driving through standing water, drive slowly
and do not stop the vehicle. When you have
passed the water, press lightly on the brake pedal
and check that the brakes are functioning prop-
erly. Water, mud, slush, etc. can make the brake
linings slippery, resulting in delayed braking
effect.

•

If the vehicle is equipped with contacts for an
electric heater or trailer coupling, clean these
after driving in water or mud.

•

Do not allow the vehicle to stand in water up
to the sills any longer than absolutely neces-
sary. This could result in electrical malfunc-
tions.

CAUTION

•

Engine damage could occur if water
enters the air cleaner.

•

If water enters the transmission, the lubri-
cating ability of the oils is reduced and
the service life of these systems is short-
ened.

•

Damage to any component, engine,
transmission, turbocharger, differential or
its internal components caused by flood-
ing, vapor lock or insufficient oil is not
covered under warranty.

•

If the engine stalls while the vehicle is in
water, do not attempt to restart it. Have
the vehicle towed out of the water to a
workshop. An authorized Volvo workshop
is recommended. Risk of engine failure.

Refueling (p. 406)

Refueling

The fuel tank is equipped with a fuel filling sys-
tem without a cover.

Refueling the vehicle at a service
station

Refueling is done as follows.

1. Turn off the engine and open the fuel filler

door.

2. Select a fuel approved for use in the vehicle.

For more information on approved fuels, see
the section on "Gasoline".

3. Insert the pump's nozzle into the fuel filler

pipe's opening. There are two flaps just
inside the fuel filler pipe and the pump's noz-
zle must push both of these flaps open
before fuel can be added.

4. Avoid overfilling the tank. Do not press the

handle on the filler nozzle again after it has
initially stopped pumping.
> The fuel tank is now filled.

NOTE

An over-full tank may overflow in hot weather.

CAUTION

Avoid spilling gasoline during refueling. In
addition to causing damage to the environ-
ment, gasolines containing alcohol can cause
damage to painted surfaces, which may not
be covered under the New Vehicle Limited
Warranty.

Refueling from a fuel container

When filling from a fuel container, use the funnel
provided in a foam block under the floor hatch in
the cargo compartment.

1. Open the fuel filler door.

2. Insert the funnel into the fuel filler pipe's

opening. There are two flaps just inside the
fuel filler pipe and the tube section of the
funnel must push both of these flaps open
before fuel can be added.

Only locking and unlocking using the remote key, Passive Entry or Volvo On Call will affect the status of the fuel filler door.

Fuel

Volvo recommends the use of detergent gaso-
line to control engine deposits.

Deposit control gasoline (gasoline with
detergent additives)

Detergent gasoline is effective in keeping injec-
tors and intake valves clean. Consistent use of
deposit control gasolines will help ensure good
driveability and fuel economy. If you are not sure
whether the gasoline contains deposit control
additives, check with the service station operator.

NOTE

Volvo recommends not using external fuel
injector cleaning systems, e.g. do not add
detergent additives to gasoline before or after
refueling.

Unleaded fuel

All Volvo vehicles have a three-way catalytic con-
verter and must only use unleaded gasoline. US
and Canadian regulations require that pumps
delivering unleaded gasoline are labeled
"UNLEADED". Only the nozzles of these pumps
will fit in your vehicle's fuel filler inlet. It is unlaw-
ful to dispense leaded fuel into a vehicle labeled
"unleaded gasoline only". Leaded gasoline dam-
ages the three-way catalytic converter and the
heated oxygen sensor system. Repeated use of
leaded gasoline will lessen the effectiveness of

the emission control system and could result in
loss of emission warranty coverage. State and
local vehicle inspection programs will make
detection of misfueling easier, possibly resulting
in emission test failure for misfueled vehicles.

NOTE

Some U.S. and Canadian gasolines contain an
octane enhancing additive called methyl-
cyclopentadienyl manganese tricarbonyl
(MMT). If such fuels are used, your Emission
Control System performance may be affected,
and the Check Engine Light (malfunction
indicator light) located on your instrument
panel may light. If this occurs, please return
your vehicle to a trained and qualified Volvo
service technician for service.

Gasoline containing alcohol and ethers,
"Oxygenated fuels"

Some fuel suppliers sell gasoline containing
"oxygenates" which are usually alcohols or
ethers. In some areas, state or local laws require
that the service pump be marked indicating use
of alcohols or ethers. However, there are areas in
which the pumps are unmarked. If you are not
sure whether there is alcohol or ethers in the
gasoline you buy, check with the service station
operator. To meet seasonal air quality standards,
some areas require the use of "oxygenated" fuel.

STARTING AND DRIVING

408

Volvo permits the use of the following "oxygen-
ated" fuels. However, the specified octane ratings
must still be met.

Alcohol - Ethanol

Fuels containing up to 10% ethanol by volume
may be used. Ethanol may also be referred to as
Ethyl alcohol, or "Gasohol".

Ethers - MTBE/ETBE: Fuels containing up to
15% MTBE/ETBE may be used.

Methanol

Do not use gasolines containing methanol
(methyl alcohol, wood alcohol). This practice can
result in vehicle performance deterioration and
can damage critical parts in the fuel system. Such
damage may not be covered under the New
Vehicle Limited Warranty.

TOP TIER Detergent Gasoline

Volvo endorses the use of "TOP TIER Detergent
Gasoline" where available to help maintain
engine performance and reliability. TOP TIER
Detergent Gasoline meets a new standard jointly
established by leading automotive manufactures
to meet the needs of today's advanced engines.
Qualifying gasoline retailers (stations) will, in
most cases, identify their gasoline as having met
the "TOP TIER Detergent Gasoline" standards.

NOTE

Information about TOP TIER Detergent Gaso-
line is available at www.toptiergas.com.

AKI (Anti Knock Index) is an average value of RON (Research Octane Number) and MON (Motor Octane Number) - (RON)+(MON)/2

For supplementary information - see the car's Service and Warranty Booklet.

STARTING AND DRIVING

409

NOTE

When switching to higher octane fuel or
changing gasoline brands, it may be neces-
sary to fill the tank more than once before a
difference in engine operation is noticeable.

Fuel Formulations

Do not use gasoline that contains lead or manga-
nese as a knock inhibitor, and do not use lead
additives. Besides damaging the exhaust emis-
sion control systems on your vehicle, lead has
been strongly linked to certain forms of cancer.

Many fuels contain benzene as a solvent.
Unburned benzene has been strongly linked to
certain forms of cancer. If you live in an area
where you must fill your own gas tank, take pre-
cautions. These may include:

•

standing upwind away from the filler nozzle
while refueling

•

refueling only at gas stations with vapor
recovery systems that fully seal the mouth of
the filler neck during refueling

•

wearing neoprene gloves while handling a
fuel filler nozzle.

Use of Additives

With the exception of gas line antifreeze during
winter months, do not add solvents, thickeners, or

other store-bought additives to your vehicle's
fuel, cooling, or lubricating systems. Overuse may
damage your engine, and some of these additives
contain organically volatile chemicals. Do not
needlessly expose yourself to these chemicals.

WARNING

Never carry a cell phone that is switched on

while refueling your vehicle. If the phone rings,

this may cause a spark that could ignite gaso-

line fumes, resulting in fire and injury.

WARNING

Carbon monoxide is a poisonous, colorless,

and odorless gas. It is present in all exhaust

gases. If you ever smell exhaust fumes inside

the vehicle, make sure the passenger com-

partment is ventilated, and immediately return

the vehicle to a trained and qualified Volvo

service technician for correction.

Demanding driving

In demanding driving conditions, e.g. when driving
in a hot climates, driving with a trailer or driving
for longer periods at higher altitudes (mountain
landscapes) than normal, it is recommended
switching to a higher octane fuel than AKI 91

changing gasoline brand to take full advantage of
your car's engine capacity and obtain the opti-
mum driving force.

Three-way catalytic converter

•

Keep your engine properly tuned. Certain
engine malfunctions, particularly involving the
electrical, fuel or distributor ignition systems,
may cause unusually high three-way catalytic
converter temperatures. Do not continue to
operate your vehicle if you detect engine
misfire, noticeable loss of power or other
unusual operating conditions, such as engine
overheating or backfiring. A properly tuned
engine will help avoid malfunctions that
could damage the three-way catalytic con-
verter.

•

Do not park your vehicle over combustible
materials, such as grass or leaves, which can
come into contact with the hot exhaust sys-
tem and cause such materials to ignite under
certain wind and weather conditions.

•

Excessive starter cranking (in excess of one
minute), or an intermittently firing or flooded
engine can cause three-way catalytic con-
verter or exhaust system overheating.

•

Remember that tampering or unauthorized
modifications to the engine, the Engine Con-
trol Module, or the vehicle may be illegal and
can cause three-way catalytic converter or
exhaust system overheating. This includes:
altering fuel injection settings or compo-
nents, altering emission system components

or location or removing components, and/or
repeated use of leaded fuel.

NOTE

Unleaded fuel is required for vehicles with
three-way catalytic converters.

Heated oxygen sensors

The heated oxygen sensors monitor the oxygen
content of the exhaust gases. Readings are fed
into a control module that continuously monitors
engine functions and controls fuel injection. The
ratio of fuel to air into the engine is continuously
adjusted for efficient combustion to help reduce
harmful emissions.

Battery drain

The electrical functions in the vehicle drain the
battery to varying degrees. Avoid using ignition
mode II when the engine is switched off. Use
ignition mode I instead, as this uses less electri-
cal current.

Note that certain accessories may also drain
power from the electrical system. Do not use
functions that use a lot of electrical current when
the engine is turned off. Examples of such func-
tions are:

•

blower

•

headlights

•

windshield wipers

•

audio system (especially at high volume).

If the starter battery voltage is low, a message is
shown in the driver display. The vehicle's energy-
saving function will then turn off or reduce certain
functions, such as the blower and/or the audio
system.

–

Charge the battery by starting the engine
and let it run for at least 15 minutes (driving
charges the battery faster than letting the
engine idle).
