Safety notes on working in the en-
gine compartment
The engine compartment of a motor vehi-
cle is a hazardous area. You should only
carry out work on the engine and in the en-
gine compartment if you know exactly how
to perform the required tasks, are aware of
the general safety procedures and have ac-
cess to the correct equipment, service flu-
ids and suitable tools. Carrying out work in-
correctly can cause serious injuries. Have all
work carried out by a suitably qualified
workshop if necessary.
Always park the vehicle on a level and sta-
ble surface before carrying out any work in
the engine compartment.
DANGER
If work is performed in the engine com-
partment during the starting proc
edure or
when the engine is running, rotating parts
(e.g. poly V-belt, alternator or radiator
fan) and the high-voltage ignition system
can cause potentially fatal injuries.
·
Always take the utmost care if you per-
form work during the starting procedure
or when the engine is running.
— Always ensure that no body parts,
jewellery, ties, loose items of clothing
or long hair get caught up in rotating
engine components. Always remove
jewellery and ties before starting
work. Tie up long hair and pull
clothes in tightly to avoid them get-
ting caught in engine parts.
— Always take due care and attention
when depressing the accelerator. The
vehicle could move even if the elec-
tric parking brake is applied.
WARNING
There are rotating components in the en-
gine compartment that can cause serious
injury.
·
Never reach into the radiator fan or into
the area of the radiator fan. Touching
the rotary blades can result in serious
injuries. T
he fan is temperature-control-
led and could start automatically -
even when the ignition is switched o.
·
Always ensure you have not le any ob-
jects, such as cleaning cloths and tools,
in the engine compartment. Any forgot-
ten items can cause malfunctions, en-
gine damage and fires.
WARNING
Unintentional vehicle movements during
servic
e work can cause serious injury.
·
Never work underneath a vehicle if it is
not secured against rolling away. If you
are working underneath the vehicle
while the wheels are on the ground, the
vehicle must be on a horizontal surface,
the wheels must be blocked and the ig-
nition switched o.
·
If you intend to work underneath the
vehicle, use suitable stands to provide
support for the vehicle. The vehicle jack
is not sucient for this task and can
fail, which can lead to serious injuries.
·
Switch o Auto StartStop.
WARNING
The engine/motor compartment of any
motor vehicle is a dangerous area. Seri-
ous injuries can be sustained here.
·
Always work with extreme care and
caution and observe the general safety
precautions. Never take any personal
risks.
·
Never perform any work on the engine
and in the engine compartment unless
you know exactly how to do so. If you
are uncertain of what to do, have the
work carried out by a suitably qualified
workshop. Serious injuries can result
from work that has not been carried out
properly.
·
Never open or close the bonnet as long
as steam or coolant is escaping. Hot
steam or hot coolant can cause serious
burns. Always wait until you can no lon-
ger see or hear steam or coolant com-
ing from the engine compartment.
·
Always allow the engine to cool down
before opening the bonnet.
