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.
An 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 button
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.

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.
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.
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.
