Vehicle maintenance and cleaning
Polishing the paintwork
Polishing brings back gloss to the paintwork. Polishing is only necessary if the paint has lost its shine, and the gloss can-
not be brought back by applying wax. Polishing products can be purchased
in your Technical Service.
The vehicle must be waxed after polishing if the polish used does not con-
tain wax compounds to seal the paint ⇒ page 218, Vehicle paint mainte-
nance.
CAUTION
To prevent damage to the paintwork:
● Do not use polishes and hard wax on painted parts with a matte finish
or on plastic parts.
● Do not polish your vehicle in a sandy or dusty environment.
Caring for plastic parts
Solvents damage plastic parts.
If normal washing fails to clean plastic parts, clean them with approved sol-
vent-free plastic cleaning and care products.
CAUTION
● The use of liquid air freshener directly over the air vents of the vehicle
may damage the plastic parts if the liquid is accidentally spilled.
● Cleaning products which contain solvents will damage the material. Cleaning windows and exterior mirrors
Cleaning windows
–
Moisten the windows with commercially available, alcohol
based glass cleaner.
– Dry the windows with a clean chamois leather or a lint-free
cloth.
Removing snow
– Use a small brush to remove snow from the windows and mir-
rors.
Removing ice
– Use a de-icer spray.
Use a clean cloth or chamois leather to dry the windows. The chamois leath-
ers used on painted surfaces are not suitable to clean windows because
they are soiled with wax deposits which could smear the windows.
If possible, use a de-icing spray to remove ice. If you use an ice scraper,
push it in one direction only without swinging it.
Use window cleaner or a silicone remover to clean rubber, oil, grease and
silicone deposits off.
Wax deposits can be removed with a special cleaner available in your Tech-
nical Services. Wax deposits on the windscreen could cause the wiper
blades to judder. Adding a window cleaner that dissolves wax to the wind-
screen washer fluid prevents wiper blades from juddering, but wax deposits
are not removed.

filler cap
– Unscrew cap from oil filler opening ⇒ Fig. 248.
– Carefully put in the specified grade of oil ⇒ page 236, adding
0.5 litres at a time.
– After two minutes, check the oil level once again ⇒ page 237.
– Where necessary, add more engine oil.
– Replace the oil filler cap carefully and push the dipstick all the
way in.
WARNING
● When refilling with oil, make sure no oil falls onto hot engine parts.
Failure to comply could result in fire.
● Wash your skin thoroughly if it comes into contact with engine oil.
CAUTION
● The oil level must never be above area a. This could damage the cata-
lytic converter or the engine. Contact a specialised workshop to drain the
engine oil if necessary.
● No additives should be used with engine oil. Any damage caused by the
use of such additives would not be covered by the factory warranty.
For the sake of the environment
● Oil must not be disposed of in the drain or on the ground.
● Always observe legal requirements when disposing of empty oil canis-
ters.
Cooling system Engine coolant specifications
The engine cooling system is supplied from the factory with a specially trea-
ted mixture of water and, at least, 40 % of the additive G 13 (TLVW 774 J).
The engine coolant additive is recognisable by its purple colour. This mix-
ture of water and additive gives the necessary frost protection down to
-25°C (-13°F) and protects the light alloy parts of the cooling system against
corrosion. It also prevents scaling and considerably raises the boiling point
of the coolant.
To protect the engine cooling system, the percentage of additive must al-
ways be at least 40 %, even in warm climates where anti-freeze protection is
not required.
If greater frost protection is required in very cold climates, the proportion of
additive can be increased. However, the percentage of additive should not
exceed 60 %, as this would reduce the frost protection and, in turn, de-
crease the cooling capacity.
