Engine oil
level low Refill 1 liter, fill only
with the indicated volume, e.g. 1 liter (1 quart).
WARNING
Do not spill oil on the hot exhaust pipes as this could cause a fire.
Viewing oil level in the center displayThe oil level can be viewed using the elec- tronic oil level gauge in the center display oncethe vehicle has been started. The oil levelshould be checked regularly.

Polishing and waxing
Polish and wax the vehicle when the paint is matte or to provide extra protection. Thevehicle does not need to be polished until it isat least a year old. However, it can be waxedduring the first year. Do not polish or wax thevehicle in direct sunlight. The surface of thevehicle should not be warmer than 45 °C(113 °F).
Wash and dry the vehicle very carefully before polishing or waxing. Removeasphalt and tar stains with asphaltremover or paint thinner. More stubbornstains can be removed with a grindingpaste designed for vehicle paint.
Use polish first and then liquid or pastewax. Follow the instructions on the pack-age carefully. Many products contain bothpolish and wax.
A wide range of polymer-based waxes canbe purchased today. These waxes are easyto use and produce a long-lasting, high-gloss finish that protects the bodyworkagainst oxidation, road dirt and fading.

CAUTION
Avoid waxing and polishing plastic and rubber. If using degreaser on plastic and rubber, only rub (if necessary) with slight pressure.Use a soft sponge. Polishing glossy trim moldings can wear away or damage the glossy surface layer. Polish containing abrasives must not be used.
CAUTION
Only use paintwork treatments recom- mended by Volvo. Other treatments, suchas preservation, sealing, protection, lustersealing or similar, could damage the paint-work. Paintwork damage caused by suchtreatments are not covered by Volvo's war-ranty.

Important to keep in mind when handwashing your vehicle
Avoid washing the vehicle in direct sun- light. This could cause the detergent orwax to dry out and become abrasive.
Remove bird droppings from paintwork assoon as possible. It contains chemicalsthat affect and discolor paintwork veryquickly. Use e.g. soft paper or a spongesoaked in lots of water. Consult an author-ized Volvo workshop for assistanceremoving discoloration.
Hose down the underbody, including thewheel housings and bumper.
Hose down the entire vehicle and removeany loose dirt, droppings etc. to reducethe risk of scratches from washing. Do notspray directly onto locks.
If necessary, use cold degreaser on heavilysoiled surfaces. Note that in such casesthe surfaces must not be hot from the sun.

A special cleaning agent available from Volvo retailers is recommended for the cleaning andcare of colored plastic parts, rubber and trimcomponents, e.g. glossy trim. Follow theusage instructions for the cleaning agent care-fully. Avoid using car washing detergents with a pH value lower than 3.5 or higher than 11.5. Doingso could result in the discoloring of anodized aluminum surfaces
* (as shown in the illustra-
tions below). Abrasive polishing agents are not recommended for these areas (as shown in the illustrations below).
Components that should be washed with a cleaning product 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, only rub (if necessary) with slight pressure.Use a soft sponge. Polishing glossy trim moldings can wear away or damage the glossy surface layer. Polish containing abrasives must not be used.

Corrosion protection Your vehicle is constructed with protection against corrosion.
Corrosion protection for the body consists of modern metallic protective coatings on thesheet metal, a high-quality painting process,corrosion-protected and minimized metaloverlap, and shielding plastic components,abrasion protection and supplemental rustinhibitor in exposed areas. In the chassis,exposed components of the wheel suspensionare made of corrosion-resistant cast alumi-num.
Inspection and maintenanceThe corrosion protection does not normallyrequire maintenance, but keeping the vehicleclean helps reduce the risk of corrosion. Theuse of strong alkaline or acidic cleaning fluidsshould be avoided on shiny body components.Any stone chips in the paint should betouched up as soon as they are discovered.
