•
Wash using a sponge, car washing detergent
and plenty of lukewarm water.
• Clean the wiper blades with lukewarm soap
solution or car washing detergent.
• Dry the vehicle using a clean, soft chamois or
a squeegee. Try not to let drops of water dry
in strong sunlight. This could cause water
drying stains that may need to be polished
out.
• In areas with heavy industrial emissions,
more frequent washing of the vehicle's exte-
rior is recommended.
• Tar spots from asphalt may remain even after
washing. Use a tar remover to remove these
spots after washing the vehicle.
WARNING Always entrust engine washing to a workshop.
If the engine is hot, there is a risk of fire.
CAUTION
Dirty headlights do not work as well. Clean
them regularly, e.g. when refueling.
Do not use corrosive cleaners. Use water and
a non-abrasive sponge.
NOTE Exterior lighting such as headlights and tail-
lights may develop temporary condensation
on the inside of the lens. This is normal. All
exterior lighting is designed to resist this.
Condensation is normally vented out of the
lamp housing once the light has been lit for
some period of time.
CAUTION
•
Make sure that the panoramic roof and
sun shade are closed before washing the
vehicle.
• Never use abrasive polishing agents on
the panoramic roof.
• Never use wax on the rubber seals
around the panoramic roof.
CAUTION Remember to remove dirt from the drain
holes in the doors and sills after washing the
vehicle.

Automatic car washes
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.
Automatic car washesAn automatic car wash is a fast and easy way to
keep your vehicle clean, but it does not reach all
areas of the vehicle. For best results, Volvo rec-
ommends hand washing your vehicle or supple-
menting automatic car washes with a hand wash.
NOTE
Volvo recommends not washing the vehicle in
an automatic car wash during the first few
months; the paintwork on new vehicles takes
some time to fully harden.
CAUTION
Before driving the vehicle into a car wash,
deactivate the Automatic Braking when Sta-
tionary and Automatic Parking Brake Applica-
tion functions. If the functions are not deacti-
vated, the brake system will seize when the
vehicle is stationary and the vehicle will not be
able to roll.
CAUTION For automatic car washes in which the vehicle
is pulled forward on rolling wheels:
1.

Before washing the vehicle, make sure
that the automatic rain sensor is deacti-
vated. If it is not deactivated and inadver-
tently starts, the wiper arms could be
damaged.
2. To help prevent damage from the auto- matic car wash machinery, make sure
that the door mirrors are folded in, anten-
nas retracted or removed, and any auxili-
ary lights secured.
3. Drive into the automatic car wash.
4. Turn off the "Automatic Braking when Stationary" function using the switch in
the tunnel console.
5. Turn off the "Automatic Parking Brake Application" function in the center dis-
play's Top view.
6. Turn off the engine by turning the start knob in the tunnel console clockwise.
Hold the knob in position for at least
2 seconds.
The vehicle is now ready for the automatic car
wash.
CAUTION The system will automatically change to P
mode if the above steps are not followed. In P
mode, the wheels are locked, which they
should not be when the vehicle is being
washed in a car wash.

Cleaning exterior plastic, rubber and
trim components
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.
Exterior plastic, rubber and trim
components
A special cleaning agent available from Volvo
retailers is recommended for the cleaning and
care of colored plastic parts, rubber and trim
components, e.g. glossy trim. Follow the usage
instructions for the cleaning agent carefully.
Avoid using car washing detergents with a pH
value lower than 3.5 or higher than 11.5. Doing
so could result in the discoloring of anodized alu-
minum surfaces* (as shown in the illustrations
below). Abrasive polishing agents are not recom-
mended for these areas (as shown in the illustra-
tions below). Components that should be washed with a cleaning
product with a pH value between 3.5 and 11.5.
CAUTION
Avoid waxing and polishing plastic and rubber.
If using degreaser on plastic and rubber, only
rub (if necessary) with slight pressure. Use a
soft sponge.
Polishing glossy trim moldings can wear away
or damage the glossy surface layer.
Polish containing abrasives must not be used.
CAUTION Avoid washing the vehicle with cleaner with a
pH value below 3.5 or above 11.5. This could
cause discoloration of anodized aluminum
components like the roof rail and around the
side windows.
Never use metal polishing agent on anodized
aluminum components. This could cause dis-
coloration and destroy the surface treatment.

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.

Paintwork (p. 645)
• Touching up minor paint damage (p. 645) Changing rear window wipers
The wiper blades help remove water from the
windshield and rear window. Along with the
washer fluid, they clean the glass and help
improve visibility while driving. The windshield
and rear window wiper blades can be replaced.
Changing rear window wipers Lift the wiper arm from the window and pull the lower
section of the blade to the right.1. Grasp the center of the wiper blade and
lift it from the window to the stop position.
NOTE When the wiper arm is halfway folded out, it
will stop in a locking position that helps pre-
vent the arm from falling back onto the rear
window. The wiper arm must be pulled past
the locking position stop in order to change
the wiper blade.
2. Grip the lower part of the blade and pull
to the right until the blade loosens from the
arm.
3.

Press the new wiper blade until it clicks into
place. Check to make sure the blade is
securely in place.
4. Fold the wiper arm back toward the window.
CAUTION Check the blades regularly. Neglected main-
tenance shortens the life of the blades.

CAUTION If the wiper arms in service position are raised
from the windshield, they must be folded back
against the windscreen before activating wip-
ing, washing or rain sensor as well as before
departure. This is to prevent scratching the
