Rustproofing

The car has protection against corrosion.

Anti-corrosion protection for the body consists
of metallic protective coatings on the sheet
metal, a high-quality painting process, corro-
sion-protected and minimised metal overlap,
and shielding plastic components, abrasion
protection and supplemental rust inhibitor on
exposed areas. In the chassis, exposed com-
ponents of the wheel suspension are made of
corrosion-resistant cast aluminium.

Inspection and maintenance

The car's anti-corrosion protection normally
requires no maintenance, but a good way to
reduce the risk of corrosion is to keep the car
clean. Strong alkaline or acidic cleaning solu-
tions must be avoided on glossy trim compo-
nents. Any stone chips should be rectified as
soon as they are discovered.

Car paintwork

The paintwork consists of several layers and
is an important part of the car's rustproofing,
and should therefore be checked regularly.

The most common types of paintwork dam-
age are stone chips, scratches, and marks on
the edges of wings, doors and bumpers. To
avoid the onset of rust, damaged paintwork
should be rectified immediately.

Touching up minor paintwork

damage

Paint is an important part of the car's rust-
proofing and should therefore be checked
regularly. The most common types of paint-
work damage are stone chips, scratches, and
marks on e.g. the edges of wings, doors and
bumpers.

To avoid the onset of rust, damaged paintwork
should be rectified immediately.

NOTE

When paint is repaired the surface must be
clean and dry. The temperature of the sur-
face should be at least 15 °C (59 °F).

Materials that may be needed

•

Primer – a special adhesive primer in a
spray can is available for e.g. plastic-
coated bumpers.

•

Basecoat and clearcoat - available in spray
cans or as touch-up pens/sticks

.

•

Masking tape.

•

Fine sand paper.

MAINTENANCE AND SERVICE

648

Applying touch-up paint to the
damaged surface

If the damage has not reached down to the
metal, the touch-up paint can be applied
directly after the surface has been cleaned.

1. Apply a piece of masking tape over the

damaged surface. Then remove the tape
to remove any loose paint.

If the damage is down to the metal, use of
a primer is appropriate. In the event of
damage to a plastic surface, an adhesive
primer should be used to give better
results - spray into the lid of the spray can
and brush on thinly.

2. Before painting, gentle polishing using a

very fine polishing agent may be carried
out locally if required (e.g. if there are any
uneven edges). The surface is cleaned
thoroughly and left to dry.

3. Stir the primer well and apply using a fine

brush, a matchstick or similar. Finish off
with a basecoat and clearcoat once the
primer has dried.

For scratches, implement the same procedure
but mask around the damaged area to protect
the undamaged paintwork.

Touch-up pens and spray paints for touching
up paintwork are available from Volvo dealers.

NOTE

If the stone chip has not penetrated down
to the meal and an undamaged layer of
paint remains in place, fill in with base coat
and clear coat as soon as the surface has
been cleaned.

Replacing windscreen wiper

blades

The wiper blades sweep water away from the
windscreen. Together with washer fluid, they
aim to clean the windscreen and ensure visi-
bility while driving. The wiper blades can be
replaced.

Fold up the wiper arm when it is in service
position. Service position is activated/
deactivated via the function view in the
centre display when the car is stationary
and the windscreen wipers are not on.
Press the button located on the wiper
blade mounting and pull straight out paral-
lel with the wiper arm.

Slide in the new wiper blade until a "click"
is heard.

3. Check that the blade is firmly installed.

4. Fold the wiper arm back towards the

windscreen.

The wiper blades are different lengths

NOTE

When replacing the wiper blades, note that
they have different lengths. The blade on
the driver's side is longer than on the pas-
senger side.

Set the wiper blades in service

position

In some situations, the windscreen's wiper
blades must be set in service position (verti-
cal position), e.g. when they shall be
replaced.

Wiper blades in service position.

In order to change, clean or lift the wiper
blades (e.g. for scraping off ice from the wind-
screen) they must be in service position.

IMPORTANT

Before placing the wiper blades in the
service position, make sure that they are
not frozen down.

Activating/deactivating service mode

Service mode can be activated/deactivated
when the car is stationary and the windscreen

wipers are not on. Service mode is activated/
deactivated via the function view in the centre
display:

Press the

Wiper Service

Position

button. The light

indicator in the button illumi-
nates when service mode is
activated. When activated,
the wipers move to the serv-
ice position. To deactivate the

service mode, press

Wiper Service Position

again. The light indicator in the button extin-
guishes when service mode is deactivated.

The wiper blades also exit the service position
if:

•

Windscreen wiping is activated.

•

Windscreen washing is activated.

•

The rain sensor is activated.

•

The car is driven away.

IMPORTANT

If the wiper arms in service position have
been folded up from the windscreen, they
must be folded back down onto the wind-
screen before the activation of wiping,
washing or the rain sensor, as well as
before driving. This is to avoid scraping the
paint on the bonnet.

Weights (p. 659)

SPECIFICATIONS

659

Weights

Max. gross vehicle weight, etc. can be read
on a label in the car.

Kerb weight includes the driver, the fuel tank
90% full, plus and all oils and fluids.

The weight of passengers and accessories,
and towball load (when a trailer is hitched)
influence the load capacity and are not
included in the kerb weight.

Permitted max. load = Gross vehicle weight -
Kerb weight.

NOTE

The documented kerb weight applies to
cars in the standard version - i.e. a car
without extra equipment or accessories.
This means that for every accessory added
the loading capacity of the car is reduced
correspondingly by the weight of the
accessory.

Examples of accessories that reduce load
capacity are the different equipment levels
(e.g. Kinetic, Momentum, Summum), as
well as other accessories such as towbar,
load carrier, space box, audio system, auxil-
iary lamps, GPS, fuel-driven heater, safety
grille, carpets, cargo cover, power seats,
etc.

Weighing the car is a certain way of ascer-
taining the kerb weight of your own partic-
ular car.

WARNING

The car's driving characteristics change

depending on how heavily it is loaded and

how the load is distributed.

The decal is positioned on the door pillar, and will be

visible when the right-hand rear door is opened.

Adverse driving conditions for

engine oil

Adverse driving conditions can lead to abnor-
mally high oil temperature or oil consump-
tion. Below are some examples of adverse
driving conditions.

Check the oil level more frequently for long
journeys:

•

towing a caravan or trailer

•

in mountainous regions

•

at high speeds

•

in temperatures colder than -30 °C
(-22 °F) or hotter than +40 °C (+104 °F).

The above also apply to shorter driving dis-
tances at low temperatures.

Choose a fully synthetic engine oil for adverse
driving conditions. It provides extra protection
for the engine.

Volvo recommends:

IMPORTANT

In order to fulfil the requirements for the
engine's service intervals all engines are
filled with a specially adapted synthetic
engine oil at the factory. The choice of oil
has been made very carefully with regard
to service life, starting characteristics, fuel
consumption and environmental impact.

An approved engine oil must be used in
order that the recommended service inter-
vals can be applied. Only use a prescribed
grade of oil for both filling and oil change,
otherwise there is a risk of the service life,
starting characteristics, fuel consumption
and environmental impact of the car being
affected.

If engine oil of the prescribed grade and
viscosity is not used, engine related com-
ponents may become damaged. Volvo Car
Corporation disclaims any liability for any
such damage.

Volvo recommends that oil changes are
carried out at an authorised Volvo work-
shop.
