Polishing and waxing
Polish and wax the vehicle when the paint ismatte or to provide extra protection. The vehicledoes not need to be polished until it is at least ayear old. However, it can be waxed during thefirst year. Do not polish or wax the vehicle indirect sunlight. The surface of the vehicle shouldnot be warmer than 45 °C (113 °F).
Wash and dry the vehicle very carefullybefore polishing or waxing. Remove asphaltand tar stains with asphalt remover or paintthinner. More stubborn stains can beremoved with a grinding paste designed forvehicle paint.
Use polish first and then liquid or paste wax.Follow the instructions on the package care-fully. Many products contain both polish andwax.
A wide range of polymer-based waxes canbe purchased today. These waxes are easy touse and produce a long-lasting, high-glossfinish that protects the bodywork against oxi-dation, road dirt and fading.

CAUTION
Avoid waxing and polishing plastic and rubber.
If using degreaser on plastic and rubber, onlyrub (if necessary) with slight pressure. Use asoft sponge.
Polishing glossy trim moldings can wear awayor damage the glossy surface layer.
Polish containing abrasives must not be used.

CAUTION
Only use paintwork treatments recommendedby Volvo. Other treatments, such as preserva-tion, sealing, protection, luster sealing or simi-lar, could damage the paintwork. Paintworkdamage caused by such treatments are notcovered by Volvo's warranty.

Hand washing
Keep the following points in mind when washingthe vehicle:
Avoid washing the vehicle in direct sunlight.This could cause the detergent or wax to dryout and become abrasive.
Remove bird droppings from paintwork assoon as possible. It contains chemicals thataffect and discolor paintwork very quickly.Use e.g. soft paper or a sponge soaked inlots of water. Consult an authorized Volvoworkshop for assistance removing discolora-tion.
Hose down the underbody, including thewheel housings and bumper.
Hose down the entire vehicle and removeany loose dirt, droppings etc. to reduce therisk of scratches from washing. Do not spraydirectly onto locks.
If necessary, use cold degreaser on heavilysoiled surfaces. Note that in such cases thesurfaces must not be hot from the sun.

CAUTION
For automatic car washes in which the vehicleis 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 buttonin the tunnel console.
5. Turn off the "Automatic Parking BrakeApplication" function in the center dis-play's Top view.
6.Turn off the engine by turning the startknob in the tunnel console clockwise.Hold the knob in position for at least2 seconds.
The vehicle is now ready for the automatic carwash.

Cleaning exterior plastic, rubber andtrim components
The vehicle should be washed as soon as itbecomes 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. Wash the vehicle in a carwash or garage with an oil separator and use carwashing detergent.

Exterior plastic, rubber and trim
components
A special cleaning agent available from Volvoretailers is recommended for the cleaning andcare of colored plastic parts, rubber and trimcomponents, e.g. glossy trim. Follow the usageinstructions for the cleaning agent carefully.
Avoid using car washing detergents with a pHvalue lower than 3.5 or higher than 11.5. Doingso could result in the discoloring of anodized alu-minum surfaces* (as shown in the illustrationsbelow). Abrasive polishing agents are not recom-mended for these areas (as shown in the illustra-tions below).
Components that should be washed with a cleaningproduct with a pH value between 3.5 and 11.5.

CAUTION
Avoid waxing and polishing plastic and rubber.
If using degreaser on plastic and rubber, onlyrub (if necessary) with slight pressure. Use asoft sponge.
Polishing glossy trim moldings can wear awayor damage the glossy surface layer.
Polish containing abrasives must not be used.
CAUTION
Avoid washing the vehicle with cleaner with apH value below 3.5 or above 11.5. This couldcause discoloration of anodized aluminumcomponents like the roof rail and around theside windows.
Never use metal polishing agent on anodizedaluminum components. This could cause dis-coloration and destroy the surface treatment.

Corrosion protection (p. 630)
Corrosion protection
Your vehicle is constructed with effective protec-tion against corrosion.
Corrosion protection for the body consists ofmodern metallic protective coatings on the sheetmetal, a high-quality painting process, corrosion-protected and minimized metal overlap, andshielding plastic components, abrasion protectionand supplemental rust inhibitor in exposed areas.In the chassis, exposed components of the wheelsuspension are made of corrosion-resistant castaluminum.
Inspection and maintenance
The corrosion protection does not normallyrequire maintenance but keeping the vehicleclean is always a good way to further reduce therisk of corrosion. The use of strong alkaline oracidic cleaning fluids should always be avoidedon shiny body components. Any stone chips inthe paint should be touched up as soon as theyare discovered.

Paintwork
The paintwork consists of multiple layers. It is animportant part of the vehicle's corrosion protec-tion and therefore needs to be checked regu-larly.
The most common types of paint damage areminor stone chips, scratches and damage to e.g.the edges of fenders, doors and bumpers. Tohelp prevent corrosion, paint damage should berectified immediately.

Touching up minor paint damage
The paintwork is an important part of the vehi-cle's corrosion protection and therefore needsto be checked regularly. The most commontypes of paint damage are minor stone chips,scratches and damage to e.g. the edges offenders, doors and bumpers.
Touching up paint damage
To help prevent corrosion, paint damage shouldbe rectified immediately.

NOTE
Make sure the surface is clean and dry beforeperforming any touch-ups to the paint. Thesurface temperature should be at least 15°C (59 °F).

Materials that might be needed
Primer19 ‒ special adhesive primer is availa-ble in a spray can for e.g. plastic-coveredbumpers.
Base coat and clear coat ‒ available in spray
cans or as a touch-up pen/stick20.
Masking tape.
Fine-grain sandpaper19.
If the damage has not reached all the way downto the metal, then touch-up paint can be appliedimmediately after the surface has been cleaned.
1. Place a strip of masking tape over the dam-aged surface. Pull the tape off so that anyloose flakes of paint adhere to it.
If the damage goes down to the bare metal,you may need to use primer first. If the paintdamage is on a plastic surface, an adhesiveprimer should be used for better results.Spray the primer into the lid of the spray canand brush on thinly.
2. Light sanding with a very fine-grained sand-paper or similar may be required beforepainting (e.g. if there are uneven edges).Clean the area carefully and let it dry.
19If required.20Follow the instructions on the packaging for the touch-up pen/stick carefully.
