• Only top up coolant if there is coolant residue in the expansion tank. If this is not observed, the
engine could be damaged. If you cannot see any coolant in the expansion tank
do not drive
on
. Seek professional assistance.
• If you can see coolant residue in the coolant expansion tank, refill coolant until the level remains
stable.
• The coolant level must be between the marks on the coolant expansion tank

Brake fluid
Hot steam or coolant can cause serious burns.
• Never open the bonnet if you can see or hear steam or engine coolant coming out of
the engine compartment. Always wait until you can no longer see or hear escaping
steam or coolant.
• Always allow the engine to cool down completely before carefully opening the bonnet.
Hot components can burn the skin.
• The following points should be noted before opening the bonnet once the engine has
cooled down:
- Switch on the electronic parking brake and move the selector lever to position P
or move the gear lever to the neutral position.
- Switch off the ignition and remove the vehicle key from the ignition lock.
- Always keep children away from the engine compartment and never leave the
vehicle unattended.
• The cooling system is under pressure when the engine is hot. Never open the cap of
the coolant expansion tank when the engine is hot. Coolant may spray out and cause
serious burns and other injuries.
- Turn the cap slowly and very carefully anti-clockwise while exerting gentle
downward pressure on the cap.
- Always protect the face, hands and arms from hot coolant or steam with a large,
thick cloth.
• When refilling, do not spill any service fluids on engine components or on the exhaust
system. The spilt service fluids can start a fire. In certain circumstances, the ethylene
glycol in the engine can catch fire.
WARNING
• Refill only with distilled water. All other types of water can cause corrosion in the
engine due to the chemical components contained therein. This can also lead to engine
failure. If any other type of water than distilled water is refilled, the fluid in the cooling
system should be completely replaced immediately by a qualified workshop.
• Do not fill coolant above the top of the marked area
⇒
Fig. 229
. Otherwise the excess
coolant will be pressed out of the cooling system when the engine is hot and could
cause damage.
• If a large amount of coolant has been lost, do not refill the coolant until the engine has
cooled completely
. Heavy coolant loss is an indication of leaks in the engine cooling
system. The engine cooling system should be checked by a qualified workshop as
soon as possible. Failure to do so can result in engine damage.
• Do not top up with coolant if there is no more coolant in the coolant expansion tank. Air
could have entered the cooling system. Do not drive on! Seek expert assistance. Failure
to do so can result in engine damage.
• When topping up service fluids, please ensure that you pour the correct service fluids
into the correct openings. The use of incorrect service fluids could result in serious
malfunctions and engine damage.
