Automatic car washes
The vehicle should be washed as soon as it becomes dirty. The longer the dirt remains,the more difficult it will be to keep the vehicleclean. It could also lead to paint damage.
Washing your vehicle in an automatic car wash is a fast and easy way to keep your vehi-cle clean, but it does not reach all areas of thevehicle. Volvo recommends washing yourvehicle by hand or supplementing automaticcar washes with a hand wash.
NOTE
Volvo recommends not washing the vehi- cle in an automatic car wash during thefirst few months; the paintwork on newvehicles takes some time to fully harden.
CAUTION
Before driving the vehicle into a car wash, deactivate the Automatic Braking whenStationary and Automatic Parking BrakeApplication functions. If the functions arenot deactivated, the brake system willseize when the vehicle is stationary and thevehicle 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 deac- tivated. If it is not deactivated andinadvertently starts, the wiper armscould be damaged.
2. To help prevent damage from the auto- matic car wash machinery, make surethat the door mirrors are folded in,antennas retracted or removed, andany auxiliary lights secured.
3. Drive into the automatic car wash.
4. Turn off the "Automatic Braking when Stationary" function using the
but-
ton 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 least2 seconds.
The vehicle is now ready for the automaticcar 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 isbeing washed in a car wash.
NOTE
Keep in mind that if the vehicle is equipped with the keyless locking and unlocking function *, the doors and tailgate/trunk lid
may open when washing the vehicle if the remote key is within range.
