MAINTENANCE AND SERVICE
644Cleaning rims
The vehicle should be washed as soon as it
becomes dirty. This makes the vehicle easier to
clean because dirt does not attach as strongly. It
also reduces the risk of scratches and keeps the
vehicle looking new. Wash the vehicle in a car
wash or garage with an oil separator. Use a car
washing detergent.
RimsOnly use rim cleaning products recommended by
Volvo.
Strong rim cleaning agents could damage the
surface and stain the chromed aluminum rims.

Your vehicle is constructed with effective protec-
tion against corrosion.
Corrosion protection for the body consists of
modern metallic protective coatings on the sheet
metal, a high-quality painting process, corrosion-
protected and minimized metal overlap, and
shielding plastic components, abrasion protection
and supplemental rust inhibitor in exposed areas.
In the chassis, exposed components of the wheel
suspension are made of corrosion-resistant cast
aluminum.
Inspection and maintenanceThe corrosion protection does not normally
require maintenance, but keeping the vehicle
clean is always a good way to further reduce the
risk of corrosion. The use of strong alkaline or
acidic cleaning fluids should always be avoided
on shiny body components. Any stone chips in
the paint should be touched up as soon as they
are discovered.

Paintwork
The paintwork consists of multiple layers. It is an
important part of the vehicle's corrosion protec-
tion and therefore needs to be checked regu-
larly.
The most common types of paint damage are
minor stone chips, scratches and damage to e.g.
the edges of fenders, doors and bumpers. To
help prevent corrosion, paint damage should be
rectified immediately.

The paintwork is an important part of the vehi-
cle's corrosion protection and therefore needs
to be checked regularly. The most common
types of paint damage are minor stone chips,
scratches and damage to e.g. the edges of
fenders, doors and bumpers.
When repairing paint damage, the vehicle must
be clean, dry and have a temperature above
15 °C (60 °F).
Touching up minor paint damageTo help prevent corrosion, paint damage should
be rectified immediately.
NOTE When repairing paintwork, it must be clean,
dry and at a temperature of at least 15°C.
Materials that might be needed
•
Primer 20
‒
special adhesive primer is availa-
ble in a spray can for e.g. plastic-covered
bumpers.
• Base coat and clear coat ‒ available in spray
cans or as a touch-up pen/stick 21
.
• Masking tape.
• Fine-grain sandpaper 20
. If the damage has not reached all the way down
to the metal, then touch-up paint can be applied
immediately after the surface has been cleaned.
NOTE Make sure the surface is clean and dry before
performing any touch-ups to the paint. The
surface temperature should be at least 15 °C
(60 °F).

If required.
21 Follow the instructions on the packaging for the touch-up pen/stick care\
fully.

1. Place a strip of masking tape over the dam-
aged surface. Pull the tape off so that any
loose flakes of paint adhere to it.
If the damage goes down to the bare metal,
you may need to use primer first. If the paint
damage is on a plastic surface, an adhesive
primer should be used for better results.
Spray the primer into the lid of the spray can
and brush on thinly.
2. Light sanding with a very fine-grained sand- paper or similar may be required before
painting (e.g. if there are uneven edges).
Clean the area carefully and let it dry.
3. Thoroughly mix the primer and apply it with a small brush, toothpick or similar. When the
primer is dry, apply one or more coats of
paint and then a clear coat, letting the paint
dry between each application.
If there is a longer scratch, follow the same pro-
cedure as above, but first mask off the surround-
ing area to protect the undamaged paint.
Touch-up pens and spray paints are available at
Volvo retailers.
NOTE If the stone chip has not gone down to the
bare metal and an undamaged coat of paint
remains, apply base coat and clear coat
immediately after cleaning the surface.
