Automatic car washes The vehicle should be washed as soon as it becomes dirty. This makes the vehicle easier toclean because dirt does not attach as strongly. Italso reduces the risk of scratches and keeps thevehicle looking new.
Automatic car washesAn automatic car wash is a fast and easy way to keep your vehicle clean, but it does not reach allareas 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 fewmonths; the paintwork on new vehicles takessome 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 thevehicle is stationary and the vehicle will not beable to roll.
CAUTION
For automatic car washes in which the vehicle is pulled forward on rolling wheels:
1. Before washing the vehicle, make surethat the automatic rain sensor is deacti- vated. If it is not deactivated and inadver-tently starts, the wiper arms could bedamaged.
2. To help prevent damage from the auto- matic car wash machinery, make surethat 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 least2 seconds.
The vehicle is now ready for the automatic carwash.
