Advice
●
Never c o
ver the engine with additional in-
sulating materials such as a blanket. Risk of
fire!
● Do not unscrew the cap on the coolant ex-
pans
ion tank when the engine is hot. If the
coolant is hot, the cooling system will be
pressurised!
● Protect face, hands and arms by covering
the cap with a l
arge, thick cloth to protect
against escaping coolant and steam.
● Always make sure you have not left any ob-
jects, s
uch as cleaning cloths or tools, in the
engine compartment.
● If you have to work underneath the vehicle,
you mus
t use suitable stands additionally to
support the vehicle, there is a risk of acci-
dent!. A hydraulic jack is insufficient for se-
curing the vehicle and there is a risk of injury.
● If any work has to be performed when the
engine is
started or with the engine running,
there is an additional, potentially fatal, safety
risk from the rotating parts, such as the drive
belts, alternator, radiator fan, etc., and from
the high-voltage ignition system. You should
also observe the following:
– Never touch the electrical wiring of the
ignition system.
– Ensure that jewellery, loose clothing and
long hair do not get trapped in rotating
engine parts. Danger of death. Before
starting any work remove jewellery, tie
back and cover hair, and wear tight-fit-
ting clothes. –
Never ac c
elerate with a gear engaged
without taking the necessary precau-
tions. The vehicle could move, even if the
handbrake is applied. Danger of death.
● If work has to be carried out on the fuel
syst
em or on electrical components, you
must observe the following safety notes in
addition to the above warnings:
– Always disconnect the battery from the
on-board network. The vehicle must be
unlocked when this is done, otherwise
the alarm will be triggered.
– Do not smoke.
– Never work near naked flames.
– Always have a fire extinguisher on hand. WARNING
If the bonnet is not correctly closed, it could
sud den
ly open while driving leaving the driv-
er without visibility. This could result in a se-
rious accident.
● After closing the bonnet, always check that
it is
properly secured by the locking mecha-
nism in the lock carrier piece. The bonnet
must be flush with the surrounding body pan-
els.
● While driving, if you notice that the bonnet
is not
correctly closed then stop immediately
and close it correctly.
● Only open and close the bonnet when there
is no
body within its range. CAUTION
When topping up service fluids, make sure
not t o mi
stake them. Using the wrong fluids
could cause serious malfunctions and engine
damage! For the sake of the environment
Service fluids leaks are harmful to the envi-
ronment . F
or this reason you should make
regular checks on the ground underneath
your vehicle. If you find spots of oil or other
fluids, have your vehicle inspected in a speci-
alised workshop. Opening the bonnet

smoke or c oo
lant escaping from the engine
compartment. 264
