Working in the engine compartment
Particular care is required when carrying out any work in the engine 
compartment!There is a risk of injuries, scalding, acci dents and fire when working in the engine 
compartment, e.g. inspecting and replen ishing oil and other fluids. For this 
reason, it is essential to comply with  the warning instructions stated below and 
with the general applicable rules of safety . The engine compartment of your car is 
a hazardous area   .
WARNING
•
Never open the bonnet if you see that steam or coolant is flowing out of the 
engine compartment - risk of scalding!  Wait long enough until the steam or 
coolant has stopped escaping.
•
Switch off the engine and pull out the ignition key.
•
Apply the handbrake firmly.
•
Move the gear lever into the Neutral position.
•
Allow the engine to cool down.
•
Keep children clear of the engine compartment.
•
Never spill oil and other fluids over the hot engine. Such fluids (e.g. the anti-
freeze contained in the coolant) may ignite!
•
Avoid short circuits in the electrical  system - particularly on the battery.
•
Never place your hand into the radiator  fan as long as the engine is still 
warm. The fan might suddenly start running!
•
Never open the cap of the coolant expans ion bottle as long as the engine is 
still warm. The cooling system is pressurized!

In cases where it be necessary to carry  out inspection work when the engine 
is running there is an additi onal risk from rotating parts (e.g. the V-ribbed belt, 
alternator, radiator fan) and from the  high-voltage ignition system. Please 
observe in addition the following: −
Never touch the electrical cables of the ignition system.
− Absolutely avoid any jewellery, loose  items of clothing or long hair from 
getting into the rotating parts of the engine - Hazard! Therefore remove any 
jewellery beforehand, tie up your hair and wear tight fitting clothing.
