Checking and refilling levels
WARNING
● Sw it
ch the engine off, remove the key from
the ignition and apply the hand brake. If the
vehicle has a manual gearbox, place the lever
in neutral; if it has an automatic gearbox,
place the selector lever in position P. Wait for
the engine to cool down.
● Keep children away from the engine com-
par
tment.
● Never spill liquids used for vehicle opera-
tion on the engine c
ompartment, as these
may catch fire (e.g. the antifreeze in coolant).
● Take care not to cause short circuits in the
electric
al system, especially when working
on the battery.
● If working inside the engine compartment,
remember th
at, even when the ignition is
switched off, the radiator fan may start up au-
tomatically, and therefore there is a risk of in-
jury.
● Never cover the engine with additional in-
su
lating materials such as a blanket. Risk of
fire!
● Do not unscrew the cap on the coolant ex-
pan
sion tank when the engine is hot. The
cooling system is under pressure.
● Protect face, hands and arms by covering
the cap w
ith a large, thick rag to protect
against escaping coolant and steam.
● If it is necessary to work in the engine com-
par
tment while the engine is running, the ro-
tating components (for example, poly-V belt, alternator, radiator fan) and the high voltage
ignition sy
s
tem are an additional hazard.
● Observe the following additional warnings
if w
ork on the fuel system or the electrical
system is necessary:
– Always disconnect the battery from the
on-board network.
– Do not smoke.
– Never work near naked flames.
– Always keep an approved fire extinguish-
er immediately available. CAUTION
When topping up fluids make sure the correct
fluid i s
put into the correct filler opening, oth-
erwise this can cause serious malfunctions or
engine damage. For the sake of the environment
Inspect the ground underneath your vehicle
r e
gularly so that any leaks are detected at an
early stage. If you find spots of oil or other
fluids in the area where it was parked, have
your vehicle inspected at the workshop. Note
In right-hand drive vehicles* some brake flu-
id r e
servoirs are on the other side of the en-
gine compartment ››› Fig. 221. Opening the bonnet
