Working in the engine compartment
Particular care is required when carrying out any work in the en-
gine compartment!
There is a risk of injuries, scalding, accidents and fire when working in the en-
gine compartment, e.g. inspecting and replenishing 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.
● If your vehicle is fitted with a manual gearbox, move the gearshift lever in-
to Neutral, or if it is fitted with automatic gearbox, move the selector lever in-
to position
P.
● Allow the engine to cool down.
● Keep children clear of the engine compartment.
● Do not touch any hot engine parts - risk of burns!
● Never spill oil and other fluids over the hot engine. Such fluids (e.g. the an-
tifreeze 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 expansion reservoir so long as the en-
gine is still warm. The cooling system is pressurized!
● Cover over the cap of the reservoir with a large cloth when opening it as
protection for your face, hands and arms from hot steam or hot coolant.
● Do not let objects, such as e.g cleaning cloth or tools lie in the engine com-
partment. WARNING (Continued)
● If you wish to work under the vehicle, you must secure the vehicle from
rolling away and support it with suitable supporting blocks: the car jack is not
sufficient for this - risk of injury!
● In cases where it be necessary to carry out inspection work when the en-
gine is running there is an additional 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.
● Please also comply with the warning instructions stated below when car-
rying out any essential work on the fuel system or on the electrical system.
–Always separate the car battery from the electrical system.
– Do not smoke.
– Never carry out any work close to naked flames.
– Always keep a working fire extinguisher at hand. CAUTION
When replenishing fluids in the engine, always ensure that the fluids are on no ac-
count mixed up. This may result in major operating problems and also vehicle
damage! 181
