fluids and consumables replaced by a Techni-
c al
Service. Please observe the relevant in-
structions ››› page 190. The engine compart-
ment of the vehicle is a hazardous area ››› .
WARNING
All work on the engine or in the engine com-
par tment, e.
g. checking and refilling fluids,
involves the danger of injury and burns, acci-
dents and even fire.
● Never open the bonnet if you see steam,
smoke or coo
lant escaping from the engine
compartment. Otherwise, there is a risk of
sustaining burns. Wait until no more steam or
coolant is emitted, then allow the engine to
cool before carefully opening the bonnet.
● Switch off the engine and remove the key
from the ignition.
● App
ly the handbrake and move the gear
lever t
o neutral or selector lever to position P.
● Keep children away from the vehicle.
● Never touch hot engine parts. There is a
risk of
burns.
● Never spill liquids on a hot engine or on a
hot exh
aust gas system. This is a fire hazard.
● Avoid causing short-circuits in the electri-
cal
system, particularly at the points where
the jump leads are attached ›››
page 52.
The battery could explode.
● Never touch the radiator fan. It is tempera-
ture c
ontrolled and could start automatically,
even when the engine has been switched off
and the key removed from the ignition! ●
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.202

Advice
Wear eye protection
Battery acid is extremely corrosive. Wear protec-
tive gloves and eye protection!
Fires, sparks, open flames and smoking are pro-
hibited!
A highly explosive mixture of gases is released
when the battery is under charge.
Keep children away from acid and batteries!
WARNING
Always be aware of the danger of injury and
chemic a
l burns as well as the risk of accident
or fire when working on the battery and the
electrical system:
● Wear eye protection. Protect your eyes,
skin and clothin
g from acid and particles con-
taining lead.
● Battery acid is extremely corrosive. Wear
protectiv
e gloves and eye protection. Do not
tilt the batteries. This could spill acid through
the vents.
● Rinse battery acid from eyes immediately
for sever
al minutes with clear water. Then
seek medical care immediately. Neutralise
any acid splashes on the skin or clothing
with a soapy solution, and rinse off with plen-
ty of water. If acid is swallowed by mistake,
consult a doctor immediately.
● Fires, sparks, open flames and smoking are
prohibit
ed. When handling cables and electri-
cal equipment, avoid causing sparks and electrostatic charge. Never short the battery
termin
a
ls. High-energy sparks can cause in-
jury.
● A highly explosive mixture of gases is re-
lea
sed when the battery is under charge. The
batteries should be charged in a well-ventila-
ted room only.
● Keep children away from acid and batteries.
● Before working on the electrical system,
you mus
t switch off the engine, the ignition
and all electrical devices. The negative cable
on the battery must be disconnected. When a
light bulb is changed, you need only switch
off the light.
● Deactivate the anti-theft alarm by unlock-
ing the v
ehicle before you disconnect the bat-
tery! The alarm will otherwise be triggered.
● When disconnecting the battery from the
vehicl
e on-board network, disconnect first
the negative cable and then the positive ca-
ble.
● Switch off all electrical devices before re-
connecting the b
attery. Reconnect first the
positive cable and then the negative cable.
Never reverse the polarity of the connections.
This could cause an electrical fire.
● Never charge a frozen battery, or one which
has
thawed. This could result in explosions
and chemical burns. Always replace a battery
which has frozen. A flat battery can also
freeze at temperatures close to 0°C (+32°F).
● Ensure that the vent hose is always connec-
ted to the b
attery. ●
Never u se a def
ective battery. This could
cause an explosion. Replace a damaged bat-
tery immediately.
● For vehicles with the battery in the luggage
compar
tment: Check that the battery gas
ventilation hose is securely attached. CAUTION
● Nev er di s
connect the battery if the ignition
is switched on or if the engine is running.
This could damage the electrical system or
electronic components.
● Do not expose the battery to direct sunlight
over a lon
g period of time, as the intense ul-
traviolet radiation can damage the battery
housing.
● If the vehicle is left standing in cold condi-
tions f
or a long period, protect the battery
from “freezing”. If it freezes it will be dam-
aged. Checking the battery electrolyte level
The electrolyte level should be checked regu-
l
arly
in high-mi
leage vehicles, in hot coun-
tries and in older batteries.
– Open the bonnet and open the battery cov-
er at the front
