Windscreen washer fluid
270WARNINGNever cover the engine with additional insulation material (e.g. with a cov-
er) – risk of fire!WARNINGWhen working in the engine compartment, the following instructions must
be observed - risk of injury or fire. The engine compartment of your car is a
hazardous area!WARNINGInstructions before beginning work in the engine compartment■Stop the engine and remove the ignition key, on vehicles with the KESSY
system, open the driver's door.■
Switch on the parking brake.
■
For vehicles with manual transmission the lever into the neutral position.
On vehicles with automatic transmission , place the selector lever in the P
position.
■
Allow the engine to cool.
■
Never open the bonnet if you can see steam or coolant flowing out of the
engine compartment – risk of scalding! Wait until the steam or coolant has
stopped escaping.
WARNINGInformation for working in the engine room■Keep everyone away from the engine compartment.■
Do not touch any hot engine parts – risk of burns!
■
Never touch the radiator fan. The radiator fan suddenly switch on approx.
10 minutes after switching off the ignition!
■
Do not smoke or use open flames in the vicinity of the engine.
■
Do not leave any items (e.g. cloths or tools) in the engine compartment.
This presents a fire hazard and the risk of engine damage.
■
Read and observe the information and warning instructions on the fluid
containers.
WARNINGInformation for working in the engine compartment with the engine run-
ning■
If it is necessary to work on the engine compartment with the engine run-
ning, then observe the rotating engine parts and electrical plants - it can
be fatal!
■
Never touch the electric wiring on the ignition system.
■
Avoid short circuits in the electrical system, particularly on the vehicle's
battery. 
268General Maintenance

The coolant additive proportion in the coolant must be between 40 and 60 %.
The correct mixing ratio of water and coolant additive should be checked if
necessary by a specialist garage or corrected if necessary.WARNING■ The following warning instructions must be followed at all times when
working in the engine compartment » page 268.■
Never open the end cover of the coolant expansion reservoir while the
engine is still warm. The cooling system is pressurized - risk of scalding or
injury from being splashed with coolant!
■
To protect against coolant splashes, cover the cap with a cloth when
opening.
■
Coolant and coolant fumes are harmful - avoid contact with the coolant. If
your eyes or skin come into contact with the coolant, immediately wash the
affected area for a few minutes long with a lot of water and seek medical
advice if required.
CAUTION
Do not cover the radiator or fit any parts (e.g. auxiliary lights) in front of the air
intakes - there is a risk of the engine overheating.
Checking and refilling
Fig. 322
Coolant expansion reservoir
Read and observe and on page 272 first.
Check the coolant under the following conditions and refill.
The vehicle is on a horizontal surface.
The engine is not warm (if the engine is warm, the test results could be
inaccurate).
The engine is turned off.
Check the coolant level - The coolant level must lie between the marks A andB» Fig. 322. If the coolant level is below the mark B, refill the coolant.
Refilling
The coolant expansion tank must always contain a small amount of coolant
»
.
›
Place a cloth over the cap of the coolant expansion tank and unscrew the
cap carefully .
›
Always top up using the correct specification of fluids.
›
Turn the cap until it clicks into place.
The specification for the coolant is shown in the coolant expansion reservoir
» Fig. 322 .
If no specified coolant is available, use only distilled or demineralised water
and have the mixing ratio of water and coolant additive corrected by a special-
ist garage as soon as possible.
CAUTION
■ If the expansion tank is empty, do not top up with coolant. The system could
aerate - risk of damaging the engine!  Stop driving! Switch off the engine
and seek assistance from a specialist garage.■
Do not fill the coolant above the mark
A
» Fig. 322 . When it heats up, the
coolant could press out of the cooling system - there is a risk of damage to the
engine parts.
■
If it is not possible to add coolant, 
stop driving! Switch off the engine and
seek assistance from a specialist garage.
■
A coolant additive which does not correspond to the correct specification can
reduce the anti-corrosion effect of the cooling system - there is a risk of dam-
age to the cooling system and the engine.
■
If water other than distilled (demineralised) water is used, then have the
coolant replaced by a specialist garage - there is a risk of engine damage.
■
A loss of coolant could be due to leaks in the cooling system - there is a risk
of engine damage. Switch off the engine and seek assistance from a specialist
garage.
Note
A coolant level which is too low is indicated in the instrument cluster by the
warning light  and shown by the relevant message » page 39. We still recom-
mend inspecting the coolant level directly at the reservoir from time to time.272General Maintenance
