Regularly remove salt and brake abrasion, otherwise the rim material will be
corroded.
Light alloy wheel trims
After washing thoroughly and treat the wheel rims with a protective product
for light alloy wheels.
For the treatment of wheel rims do not use products which may cause damage
to the paint on the rims.
CAUTION
■ Damage to the paint layer on the wheel rims must be touched up immediate-
ly.■
Severe layers of dirt on the wheels can also result in wheel imbalance. This
may show itself in the form of a wheel vibration which is transmitted to the
steering wheel which, in certain circumstances, can cause premature wear of
the steering. This means it is necessary to remove the dirt.
Under-body protection
Read and observe
and on page 195 first.
The underside of your vehicle is already permanently protected by the factory
against chemical and mechanical influences.
It is not possible to guarantee that the protective coating will not suffer any
damage as the vehicle is driven.
We recommend having the protective coating underneath the vehicle and the
chassis checked — preferably before the beginning of winter and at the end of
winter.
WARNINGNever use additional underbody protection or anti-corrosion agents for ex-
haust pipes, catalytic converters, diesel particle filters or heat shields.
When the engine reaches its operating temperature, these substances may ignite - risk of fire!Wiper blades
Read and observe
and on page 195 first.
Clean the wiper blades regularly with a glass cleaner. The wiper blades should
be cleaned with a sponge or cloth if they are heavily soiled by insect residues,
for example.
The wiper blades can become soiled with wax residues after washing in auto-
matic vehicle wash systems for example.

the exhaust system.■
Immediately remove any fuel that has spilled onto the vehicle's paintwork –
risk of paint damage.
■
If the vehicle was not purchased in the country where it was intended to be
operated, you should check whether the fuel specified by the manufacturer is
offered in the country where the vehicle will be operated. You should also per-
haps check whether the manufacturer has recommended a different fuel for
operation of the vehicle in the corresponding country. If no prescribed fuel is
available, then you must check whether it is permitted by the manufacturer to
operate the vehicle with another fuel type.

Incorrect refuelling guard on vehicles with diesel engines
The fuel filler tube on vehicles with diesel engines has been fitted with a in-
correct refuelling guard » Fig. 225. This guard means it is only possible to re-
fuel with the diesel pump nozzle.
If the diesel pump nozzle does not sit directly in the fuel filler tube, move it to
and fro with slight pressure to insert it correctly.
WARNINGInstructions for filling the reserve canister■Never fill the reserve can inside the vehicle.■
Never place the reserve can on the vehicle.
■
Always place the reserve can on the floor.
■
We do not recommend carrying any fuel canisters in your vehicle for safe-
ty reasons. in the event of an accident, these canisters can become dam-
aged and fuel may escape – risk of fire!
CAUTION
■ The fuel tank is full just as soon as the pump nozzle switches off for the first
time, provided the nozzle has been operated properly. Not continue refuelling.■
Be careful when filling diesel fuel from the spare canister and then do this
slowly and cautiously – danger of contaminating the body.
■
The diameter of the diesel pump nozzle can be identical to that of the petrol
pump nozzle in some countries. When driving in these countries, the incorrect
fuelling protection should be removed by a specialist company.

202General Maintenance

Preheating fuel
The vehicle is fitted with a fuel filter preheating system. This secures opera-
tion of a vehicle using diesel fuel down to an environmental temperature of
-24 °C.
Diesel fuel additives
The diesel fuel in accordance with the prescribed standards meets all the con-
ditions for a smooth running engine. We therefore recommend that no diesel
fuel additives are used. This can result in considerable damage to parts of the
engine or the exhaust system.
CAUTION
■ Just filling the tank once with diesel fuel that does not comply with the
standard, can cause severe damage to parts of the engine, the fuel and ex-
haust system.■
If a different fuel other than diesel fuel, which complies to the above men-
tioned standards (e.g. petrol) is put into the tank, do not start the engine or
switch on the ignition! Extensive damage to engine parts can occur.
■
Water which has collected in the fuel filter can cause engine faults.
CAUTION
■ The vehicle cannot be operated with biofuel RME, therefore this fuel must
not be refuelled and driven. The use of biofuel RME can cause considerable
damage to parts of the engine or fuel system.■
Do not mix any fuel additives, so-called “flow improvers” (petrol and similar
agents) into the diesel. This can result in considerable damage to parts of the
engine or the exhaust system.

Coolant
Introduction
This chapter contains information on the following subjects:
Checking the coolant level
211
Replenishing
212
The coolant provides cooling for the motor.
It consists of water and coolant additive with additives that protect the cooling
system against corrosion and prevents furring. 
210General Maintenance

The proportion of coolant additive in the mixture must be at least 40%.
The coolant additive may be increased to a maximum of 60%.
The correct mixing ratio of water and coolant additive is to be checked if nec-
essary by a specialist garage or is to be restored if necessary.
The description of the coolant is shown in the coolant expansion reservoir
» Fig. 231 on page 211 .WARNINGThe engine compartment of your car is a hazardous area. The following
warning instructions must be followed at all times when working in the en- gine compartment » page 206.■
The coolant is harmful to health.
■
Avoid contact with the coolant.
■
Coolant vapours are harmful to health.
■
Never open the end cover of the coolant expansion reservoir while the
engine is still warm. The cooling system is pressurized!
■
When opening the end cover of the coolant expansion reservoir, cover it
with a cloth to protect your face, hands and arms from hot steam or hot
coolant.
■
If any coolant splashes into your eyes, immediately rinse out your eyes
with clear water and contact a doctor as soon as possible.
■
Always keep the coolant in the original container, safe from people who
are not completely independent, especially children - there is a danger of
poisoning!
■
If coolant is swallowed, consult a doctor immediately.
■
Never spill operating fluids over the hot engine - risk of fire.
CAUTION
■  Do not continue if for some reason it is not possible to fill with coolant un-
der the current circumstances! Switch off the engine and seek assistance from
a specialist garage.■
If the expansion tank is empty, do not top up with coolant. The system could
ventilate - there is a risk of engine damage, 
not continue! Switch off the en-
gine and seek assistance from a specialist garage.
■
The concentration of coolant additive in the coolant must never be under
40%.
■
Over 60% of coolant additive in the coolant reduces the antifreeze protec-
tion and cooling effect.
■
A coolant additive that does not comply with the correct specification can
significantly reduce the corrosion protection of the cooling system.
■ Any faults resulting from corrosion may cause a loss of coolant and can con-
sequently result in major engine damage.■
Do not fill the coolant above the mark
A
» Fig. 231 on page 211 .
■
If an error occurs, leading to the engine overheating, the help of a professio-
nal garage is to be sought - there is a risk of serious engine damage occurring.
■
Additional headlights and other attached components in front of the air inlet
impair the cooling efficiency of the coolant.
■
Never cover the radiator - there is a risk of the engine overheating.
Note
The coolant capacity is approximately 1 l greater on vehicles that are fitted
with an auxiliary heater (auxiliary heating and ventilation).
