Hot steam or engine 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 no escaping steam or coolant can be seen or
heard.
•Always allow the engine to cool down completely before carefully opening the bonnet. Hot
components can burn the skin.
•Before opening the bonnet once it has cooled down:
- Apply the handbrake fully and move the selector lever to position N or move the
manual gear lever to the neutral position.
- Remove the vehicle key from the ignition lock.
- Always keep children away from the engine compartment and never leave the
vehicle unattended.
•The engine 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 injuries.
- Turn the cap slowly and very carefully anticlockwise while exerting some 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 is refilled, the fluid in the engine cooling system should be
completely replaced immediately by a qualified workshop.
•Do not fill coolant above the top of the marked area ⇒ Fig. 123. 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
