129WARNINGInjuries or scolding or risks of accident or fire may occur when working in the
engine compartment. For this reason, it is essential to comply with the warn- ing instructions outlined below and with the general applicable safety rules.
The engine compartment of your car is a hazardous area!WARNINGThe following instructions must be followed before starting work in the en-
gine compartment:■
Turn off the engine and withdraw the ignition key.
■
Firmly apply the handbrake.
■
If the vehicle is fitted with a manual gearbox, move the gearshift lever into
Neutral, or if the vehicle is fitted with an automatic gearbox, move the selec-
tor lever into position N.
■
Allow the engine to cool.
■
Never open the bonnet if you can see steam or coolant escaping from the
engine compartment – risk of scalding! Wait until no more steam or coolant is
escaping.
WARNINGThe following instructions must be followed when working in the engine com-
partment.■
Keep children clear of the engine compartment.
■
Never touch the radiator fan while the engine is still warm. The fan might
suddenly start running!
WARNING (Continued)■ Do not touch any hot engine parts – risk of burns!■The coolant additive and thus all of the coolant is harmful to your health.■
Avoid contact with the coolant.
■
Coolant vapours are harmful to health.
■
Never open the end cover of the coolant expansion reservoir while the en-
gine 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 cool-
ant.
■
If any coolant splashes into your eyes, immediately rinse out your eyes with
clear water and contact a doctor as soon as possible.
■
Always store the coolant additive securely in its original container, and in
particular out of the reach of children – risk of poisoning!
■
If coolant is swallowed, consult a doctor immediately.
■
Do not leave any items (e.g. cloths or tools) in the engine compartment.
■
Never spill fluids on the hot engine. Such fluids (e.g. the antifreeze con-
tained in the coolant) may ignite!
WARNINGThe following warning instructions must be observed at all times when work-
ing in the engine compartment while the engine is running.■
Pay particular attention to rotating engine parts (e.g. V-ribbed belt, genera-
tor, radiator fan) and the high-voltage ignition system – risk to life!
■
Never touch the electric wiring on the ignition system.
■
Avoid short circuits in the electrical system – particularly on the vehicle's
battery.
■
Always make sure that no jewellery, loose clothing or long hair can get
caught in rotating engine parts – risk to life! Always remove any jewellery, tie
back long hair and wear tight fitting clothing before completing any work.
WARNINGThe following warning instructions must be observed if work has to be carried
out on the fuel or electrical systems.■
Always disconnect the vehicle battery from the electrical system.
■
Do not smoke.
■
Never work near open flames.
■
Always have a functioning fire extinguisher nearby. 

The coolant consists of water with coolant additive. This mixture guarantees anti- freeze protection, protects the cooling/heater system against corrosion and pre-
vents lime formation.
Vehicles exported to countries with a mild climate are already factory-filled with
a coolant which offers antifreeze protection down to about -25 ℃. In these coun-
tries, the concentration of coolant additive should be at least 40%.
Vehicles exported to countries with a cold climate are already factory-filled with a
coolant which offers antifreeze protection down to about -35 °C. In these coun-
tries, the concentration of coolant additive should be at least 50%.
If a higher concentration of antifreeze is required for climatic reasons, the con-centration of coolant additive can be increased up to a maximum of 60% (anti-
freeze protection down to approx. -40 °C).
When refilling, only use the antifreeze with the title given on the coolant expan-
sion tank » Fig. 108 on page 132.
WARNING■
The 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 127.■
Do not continue your journey if for some reason it is not possible  to top
up the coolant under the prevailing conditions! Switch off the engine and seek
assistance from a specialist garage.
CAUTION
■ The concentration of coolant additive in the coolant must never be under 40%.■Over 60% of coolant additive in the coolant reduces the antifreeze protection
and cooling effect.■ A coolant additive that does not comply with the correct specifications can sig-
nificantly reduce the corrosion protection.■
Any faults resulting from corrosion may cause a loss of coolant and can conse-
quently result in major engine damage!
■
Do not fill the coolant above the mark
A
» Fig. 108 on page 132.
■
If a fault causes the engine to overheat, we recommend visiting a specialist ga-
rage, as otherwise serious engine damage may occur.

132General Maintenance

›Check the level of coolant in the coolant expansion bottle
» Fig. 108. The cool-
ant level when the engine is cold must lie between the “MIN” and “MAX” mark-
ings. The level may also rise slightly above the “MAX” marking when the engine is warm.
If the coolant level in the coolant expansion tank is too low, this is indicated by
the warning light  lighting up in the instrument cluster » page 18,  Coolant .
We still recommend inspecting the coolant level directly at the reservoir from
time to time.
Loss of coolant
A loss of coolant is first and foremost an indication of a leak in the system. Do
not merely top up the coolant. Have the cooling system checked by a specialist
garage.

Replenishing
First read and observe the introductory information and safety warn-
ings
on page 132.
Only top up with new coolant.
›
Switch off the engine.
›
Allow the engine to cool.
›
Place a cloth over the cap of the coolant expansion tank and unscrew the cap carefully .
›
Replenish the coolant.
›
Turn the cap until it clicks into place.
Do not use an alternative additive if the specified coolant is not available in an emergency. In this case, use just water and have the correct mixing ratio of water
and coolant additive restored by a specialist garage as soon as possible.
