Only use cleaning agents and car care prod- ucts recommended by Volvo. Clean regularlyand treat stains immediately. It is importantto vacuum before using a cleaning agent.
Volvo's leather upholstery * is treated to pro-
tect its original appearance. Over time, sun- light, grease, dirt, etc. could break down theprotective layer. This could result in scratchesand cracking. Leather upholstery * is a natural product that
changes and acquires a beautiful patina over time. Regular cleaning and treatments arerequired to preserve the qualities and color ofthe leather. Volvo offers a comprehensiveproduct, Volvo Leather Care KitWipes, forcleaning and treating leather upholstery.When used as directed, it helps preserve theleather's protective coating. For optimal results, Volvo recommends clean- ing and applying protective cream one to fourtimes a year (or more often as needed). VolvoLeather Care Kit 951 0251 and Volvo LeatherSoftener 943 7429 are available for purchaseat Volvo retailers.
Cleaning the leather upholstery1. Apply the leather cleaner to a damp sponge and squeeze it until the cleanerfoams. 2. Move the sponge in circular motions to
apply the foam to the stain.
3. Dampen the stain thoroughly with the sponge. Let the sponge absorb the stainand do not rub.
4. Dry the stain using a soft towel and let the leather dry completely.
Protecting the leather upholstery1. Apply a small amount of leather protectorto a cloth and then apply the protector tothe leather using light circular movements.
2. Let it dry for approximately 20 minutes. > Protecting the leather upholsterymakes it better able to withstand sun-light's harmful UV rays.

Wash using a sponge, car washing deter- gent and plenty of lukewarm water.
Clean the wiper blades with lukewarmsoap solution or car washing detergent.
Dry the vehicle using a clean, soft chamoisor a squeegee. Try not to let drops ofwater dry in strong sunlight. This couldcause water drying stains that may needto be polished out.
In areas with heavy industrial emissions,more frequent washing of the vehicle'sexterior is recommended.
Tar spots from asphalt may remain evenafter washing. Use a tar remover toremove these spots.
WARNING
Always entrust engine washing to a work- shop. If the engine is hot, there is a risk offire.
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 taillights may develop temporary conden-sation on the inside of the lens. This is nor-mal. All exterior lighting is designed toresist this. Condensation is normally ven-ted out of the lamp housing once the lighthas been lit for some period of time.
CAUTION
Make sure that the panoramic roof and sun shade are closed before washingthe vehicle.
Never use abrasive polishing agents onthe panoramic roof.
Never use wax on the rubber sealsaround the panoramic roof.

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.
