MAINTENANCE AND SERVICE

362

Location of the batteries

Starter battery

Support battery

The support battery normally requires no more
service than the normal starter battery. A work-
shop should be contacted in the event of ques-
tions or problems - an authorised Volvo workshop
is recommended.

IMPORTANT

If the following instruction is not observed
then the Start/Stop function may temporarily
cease to work after the connection of an
external battery or battery charger:

•

The negative battery terminal on the car's
starter battery must never be used for
connecting an external battery or battery
charger - only the car chassis may be
used as the grounding point.

See Jump starting (p. 271) for a description
of how the cable clamps must be attached.

NOTE

If the starter battery has been discharged so
much that the car has no normal electrical
functions and the engine is then jump-started
with an external battery or a battery charger,
the Start/Stop function will continue to be
activated. If the Start/Stop function then
auto-stops the engine shortly after, there is a
great risk that engine auto-start will fail due
to insufficient battery capacity, because the
battery has not had the opportunity to
recharge.

If the car has been jump-started, or if there is
insufficient time to charge the battery with a
battery charger, the recommendation is to
temporarily deactivate the Start/Stop function
until the battery has been recharged by the
car. In an outside temperature of +15 °C, the
battery needs to be charged for at least
1 hour by the car. In a lower outside tempera-
ture, the charging time may increase to
3-4 hours. The recommendation is to charge
the battery using an external battery charger.

For more information on charging the starter
battery, see Starter battery - general (p. 358).

Electrical system

The electrical system is single-pole and uses the
chassis and engine casing as a conductor.

The car has a voltage-regulated AC alternator.

The size, type and performance of the starter bat-
tery depend on the car's equipment and function.

IMPORTANT

If the starter battery is replaced, make sure
you replace it with a battery with the same
cold starting capacity and type as the original
battery (see the label on the battery).

Fuses - general

All electrical functions and components are pro-
tected by a number of fuses in order to protect
the car's electrical system from damage by short
circuiting or overloading.

If an electrical component or function does not
work, it may be because the component's fuse
was temporarily overloaded and failed. If the
same fuse fails repeatedly then there is a fault in
the circuit. Volvo recommends that you visit an
authorised Volvo workshop for checking.

Changing

1. Look in the fuse diagram to locate the fuse.

2. Pull out the fuse and check from the side to

see whether the curved wire has blown.

3. If this is the case, replace it with a new fuse

of the same colour and amperage.

WARNING

Never use a foreign object or a fuse with an

amperage higher than that specified when

replacing a fuse. This could cause significant

damage to the electrical system and possibly

lead to fire.

Car wash

The car should be washed as soon as it
becomes dirty. Wash the car in a car wash with
oil separator. Use car shampoo.

Handwashing

•

Remove bird droppings from the paintwork
as soon as possible. Bird droppings contain
chemicals that affect and discolour paintwork
very quickly. An authorised Volvo workshop is
recommended for the removal of any discol-
oration.

•

Hose down the underbody.

•

Rinse the entire car until the dissolved dirt
has been removed so as to reduce the risk of
scratches from washing. Do not spray directly
onto the locks.

•

If necessary, use cold degreasing agent on
very dirty surfaces. Note that in this case, the
surfaces must not be hot from the sun!

•

Wash using a sponge, car shampoo and
plenty of lukewarm water.

•

Clean the wiper blades with a lukewarm soap
solution or car shampoo.

•

Dry the car using a clean, soft chamois or a
water scraper. If you avoid allowing drops of
water to dry in strong sunlight, you reduce
the risk of water drying stains which may
need to be polished out.

WARNING

Always have the engine cleaned by a work-

shop. There is a risk of fire if the engine is hot.

IMPORTANT

Dirty headlamps have impaired functionality.
Clean them regularly, when refuelling for
example.

Do not use any corrosive cleaning agents or
cleaning agents with a pH value lower than
3.5 or higher than 11.5. Use water and a non-
scratching sponge.

NOTE

Outside lighting such as headlamps and rear
lamps may temporarily have condensation on
the inside of the lens. This is normal, all exte-
rior lighting is designed to withstand this.
Condensation is normally vented out of the
lamp housing when the lamp has been
switched on for a time.

Automatic car washes

An automatic car wash is a simple and quick way
of washing the car, but it cannot reach every-
where. Handwashing the car is recommended for
achieving optimum results.

NOTE

The car must only be washed by hand over
the first few months. This is because the paint
is more delicate when it is new.

IMPORTANT

If the car is painted with a matte clear coat,
never use a washing program that finishes
with hot wax treatment.

High-pressure washing

When using high-pressure washing, use sweep-
ing movements and make sure that the nozzle
does not come closer than 30 cm to the surface
of the car (the distance applies to all exterior
parts). Do not spray directly onto the locks.

Testing the brakes

WARNING

Always test the brakes after washing the car,

including the parking brake, to ensure that

moisture and corrosion do not attack the

brake linings and reduce braking perform-

ance.

Lightly depress the brake pedal now and then
when driving long distances in rain or slush. The
heat from the friction causes the brake linings to
warm up and dry. Do the same thing after starting
in very damp or cold weather.

MAINTENANCE AND SERVICE

* Option/accessory.

373

Wiper blades

Asphalt, dust and salt residue on wiper blades, as
well as insects, ice etc. on the windscreen, impair
the service life of wiper blades.

For cleaning:

–

Set the wiper blades to the service position;
see Wiper blades (p. 355).

NOTE

Wash the wiper blades and windscreen regu-
larly with lukewarm soap solution or car
shampoo.

Do not use any strong solvents.

Exterior plastic, rubber and trim
components

A special cleaning agent available from Volvo
dealers is recommended for the cleaning and
care of coloured plastic parts, rubber and trim
components, such as glossy trim mouldings.
When using such a cleaning agent the instruc-
tions must be followed carefully.

The frames around the side windows, the car's
roof rails and the door frames at the windows

are produced in anodised aluminium. This means
that they should only be washed using a cleaning
agent with a pH value between 3.5 and 11.5.
This is in order to avoid discolouration.

Parts that should be washed using a cleaning agent with

a pH value between 3.5 and 11.5.

IMPORTANT

Avoid waxing and polishing on plastic, rubber
and on parts painted in matte or semi-matte
version.

When using degreasant on plastic and rubber,
only rub with light pressure if it is necessary.
Use a soft washing sponge.

Polishing glossy trim mouldings could wear
away or damage the glossy surface layer.

Polishing agent that contains abrasive must
not be used.

IMPORTANT

Avoid washing the car with cleaning agent
with a pH value lower than 3.5 or higher than
11.5. This may result in discolouration of ano-
dised aluminium parts such as roof rack and
around the side windows.

Never use metal polishing agent on anodised
aluminium parts, this can result in discoloura-
tion and destroy the surface treatment.

Rims

Only use rim cleaning agent recommended by
Volvo.

After washing, discolouration at the base of the
spokes may remain due to metal dust from the
brake discs attaching in the wheel rim's paint.
Paint cleaner works in many cases, with very fine
polishing using a soft cloth.

Strong rim cleaning agents can damage the sur-
face and cause stains on chrome-plated alumi-
nium rims.

Polishing and waxing

Polish and wax the car if the paintwork is dull or
to give the paintwork extra protection.

The car does not need to be polished until it is
at least one year old. However, the car can be
waxed during this time. Do not polish or wax the
car in direct sunlight.

Wash and dry the car thoroughly before you
begin polishing or waxing. Clean off asphalt and
tar stains using tar remover or white spirit. More
stubborn stains can be removed using fine rub-
bing paste designed for car paintwork.

Polish first with a polish and then wax with liquid
or solid wax. Follow the instructions on the pack-
aging carefully. Many preparations contain both
polish and wax.

IMPORTANT

Avoid waxing and polishing on plastic, rubber
and on parts painted in matte or semi-matte
version.

When using degreasant on plastic and rubber,
only rub with light pressure if it is necessary.
Use a soft washing sponge.

Polishing glossy trim mouldings could wear
away or damage the glossy surface layer.

Polishing agent that contains abrasive must
not be used.

IMPORTANT

Only paint treatment recommended by Volvo
should be used. Other treatment such as pre-
serving, sealing, protection, lustre sealing or
similar could damage the paintwork. Paint-
work damage caused by such treatments is
not covered by Volvo warranty.

Matte clear coat

When the car is painted in a matte clear coat, the
following must be considered in order to avoid
paint damage due to incorrect treatment.

IMPORTANT

Never polish a matte clear coat. Polishing
leads to the paint becoming shiny.

Do not use paint cleaner, grinding agents,
polishing products or sheen preservation, e.g.
wax. These products are only intended for
glossy surfaces. If they are used on matte
paint then there will be significant damage to
the surfaces (glossy spots).

IMPORTANT

•

If wax gets onto the matte paint surface
then it must be removed immediately
using standard type white benzene.

•

Make sure you do not get resin, grease or
oil on the car's paint. They may leave resi-
dues. Remove immediately using stand-
ard type white benzene.

Proceed with caution and do not press too
hard on the painted surface.

Water and dirt-repellent coating

The windows are treated with a surface coating
that improves visibility in difficult weather condi-
tions.

Water and dirt-repellent coating

There is natural wear of the water-
repellent coating.

Maintenance:

•

Never use products such as car wax,
degreaser or similar on glass surfaces as this
could ruin their water-repellent properties.

•

Take care when cleaning so as not to dam-
age the glass surface.

•

To avoid damaging glass surfaces when
removing ice – only use plastic ice scrapers.

•

Treatment with a special finishing agent
available from Volvo dealers is recommended
in order to maintain the water-repellent prop-
erties on the side windows. This should be
used first after three years and then each
year.

IMPORTANT

Do not use a metal ice scraper to remove ice
from the windows. Use the heating to remove
ice from the door mirrors; see Windows and
door mirrors - heating (p. 107).

Rustproofing

The car received a thorough and complete rust-
proofing at the factory. Parts of the body are
made of galvanised sheet metal. The underbody
is protected by a wear-resistant anti-corrosion
compound. A thin, penetrating rustproofing fluid
was sprayed into the exposed members, cavi-
ties, closed sections and side doors.

Inspection and maintenance

The car's anti-corrosion protection does not nor-
mally need to be maintained, but keeping the car
clean always helps to further reduce the risk of
corrosion. Strong alkaline or acidic cleaning solu-
tions must always be avoided on the glossy trim
components. Any stone chips should be rectified
as soon as they are discovered.

Cleaning the interior

Only use cleaning agents and car care products
recommended by Volvo. Clean regularly and
treat stains at once for best results. Vacuuming
is important prior to using cleaning agents.

IMPORTANT

•

Certain items of coloured clothing (e.g.
dark jeans and suede garments) may
stain the upholstery. If this occurs, it is
important to clean and treat these parts
of the upholstery as soon as possible.

•

Never use strong solvents such as
washer fluid, pure petrol or white spirit to
clean the interior, since this may damage
the upholstery as well as other interior
materials.

•

Never spray the cleaning agent directly
onto components that have electrical but-
tons and controls. Wipe them instead
using a moistened cloth containing the
cleaning agent.

•

Sharp objects and Velcro may damage
the fabric upholstery.

Fabric upholstery and ceiling upholstery

Volvo offers a comprehensive fabric care product
for fabric upholstery and ceiling upholstery which,
when used in accordance with the instructions,
preserves the properties of the upholstery. The

fabric care product is available for purchase from
a Volvo dealer.

Leather upholstery

Volvo's leather upholstery is treated to preserve
its original appearance.

Leather upholstery is a natural product that
changes and acquires a beautiful patina over
time. Regular cleaning and treatment are
required in order that the properties and colours
of the leather shall be preserved. Volvo offers a
comprehensive product, Volvo Leather Care Kit/
Wipes, for the cleaning and treatment of leather
upholstery which, when used in accordance with
the instructions, preserves the leather's protective
coating.

To achieve best results, Volvo recommends the
cleaning and application of the protective cream
once to four times per year (or more if required).
The Volvo Leather Care Kit/Wipes is available for
purchase from a Volvo dealer.

Leather steering wheel

Leather needs to breathe. Never cover the
leather steering wheel with protective plastic.
Volvo Leather Care Kit/Wipes is recommended
for cleaning the leather steering wheel.

Interior plastic, metal and wood parts

A fibrillated fibre or microfibre cloth, lightly mois-
tened with water, available from a Volvo dealer, is
recommended for cleaning interior parts and sur-
faces.

Do not scrape or rub stains. Never use strong
stain removers. A special cleaning agent available
from Volvo dealers can be used for more difficult
cleaning.

Seatbelts

Use water and a synthetic detergent. A special
textile cleaning agent is available from a Volvo
dealer. Ensure that the seatbelt is dry before
allowing it to retract.

Inlay mats and floor mat

Remove inlaid carpets for separate cleaning of
the floor carpet and the inlaid carpets. Use a vac-
uum cleaner to remove dust and dirt. Each inlay
mat is secured with pins.

Remove the inlay mat by taking hold of the inlay
mat at each pin and lifting the mat straight up.

Fit the inlay mat in place by pressing it in at each
pin.

WARNING

Only use one inlaid mat at each seat, and

check before setting off that the mat by the

driver's seat is firmly affixed and secured in

the pins so that it does not get caught adja-

cent to and under the pedals.

A special textile cleaner is recommended for
stains on the floor mat after vacuuming. Floor
mats must be cleaned with agents recommended
by a Volvo dealer.
