•
Wash using a sponge, car washing detergent and plenty of lukewarm water.
• Clean the wiper blades with lukewarm soapsolution or car washing detergent.
• Dry the vehicle using a clean, soft chamois ora squeegee. Try not to let drops of water dryin strong sunlight. This could cause waterdrying stains that may need to be polishedout.
• In areas with heavy industrial emissions,more frequent washing of the vehicle's exte-rior is recommended.
• Tar spots from asphalt may remain even afterwashing. Use a tar remover to remove thesespots 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 condensationon the inside of the lens. This is normal. Allexterior lighting is designed to resist this.Condensation is normally vented out of thelamp housing once the light has been lit forsome period of time.
CAUTION
• Make sure that the panoramic roof and sun shade are closed before washing thevehicle.
• Never use abrasive polishing agents onthe panoramic roof.
• Never use wax on the rubber sealsaround the panoramic roof.
CAUTION
Remember to remove dirt from the drain holes in the doors and sills after washing thevehicle.

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.
