Safety
Control lamp for airbag and seat belt
tensioner The control lamp monitors all airbags and
seat belt tensioners in the vehicle, including
control units and wiring connections.
Monitoring of airbag and belt tensioner
system
Both the airbag and belt tensioner systems
operation is constantly monitored electroni-
cally. The control lamp
 will light up for a
few seconds every time the ignition is switch-
ed on (self-diagnosis).
The system must be checked when the
control lamp  :
● does not light up when the ignition is
switched on,
● turns off after 4 seconds after the ignition
is switched on
● turns off and then lights up again after the
ignition is switched on
● illuminates or flashes while the vehicle is
moving.
In the event of a malfunction, the warning
lamp remains on continuously. Have the air-
bag system inspected immediately by a spe-
cialised workshop.
If any of the airbags are disabled by a Techni-
cal Service, the warning lamp flashes for sev- eral more seconds after verification and will
turn off if there is no fault. WARNING
● If there is a malfunction, the airbag and
belt tensioner system cannot properly per-
form its protective function.
● If a malfunction occurs, have the system
checked immediately by a specialised work-
shop. Otherwise, in the event of an accident,
the airbag system and belt tensioners may
not be triggered, or may not be triggered cor-
rectly. Airbag overview

Checking and refilling levels
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 accelerate 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
system 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. CAUTION
When topping up service fluids, make sure
not to mistake 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. For 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
Read the additional information carefully
›››  page 10
The bonnet is released from inside the vehi-
cle.
Before opening the bonnet ensure that the
windscreen wipers are in rest position. WARNING
Hot coolant can scald!
● Never open the bonnet if you see steam,
smoke or coolant escaping from the engine
compartment. ●
Wait until no more steam, smoke or coolant
is emitted from the bonnet, then carefully
open the bonnet.
● When working in the engine compartment,
always observe the safety warnings
››› page 166. Closing the bonnet
–
Slightly lift the bonnet.
– Release the bonnet stay and replace it in its
support.
– At a height of approximately 30 cm let it fall
so it locks.
If the bonnet does not close, do not press
downwards. Open it again and let it fall as
mentioned above. WARNING
If the bonnet is not closed properly, it could
open while you are driving and completely
obscure your view of the road. Risk of acci-
dent.
● After closing the bonnet, always check that
it is properly secured. The bonnet must be
flush with the surrounding body panels.
● If you notice that the bonnet latch is not se-
cured when the vehicle is moving, stop the
vehicle immediately and close the bonnet
properly. Risk of accident. 167Technical specifications

Fuses and bulbs
Fuses and bulbs Fuses Introduction Due to the constant updating of vehicles,
fuse assignments based on equipment and
the use of the same fuse for various electrical
components, it is not possible to provide an
up-to-date summary of the fuse positions for
the electrical components at the time this
manual was printed. For detailed information
about the fuse positions, please consult a
technical service.
In general, a fuse can be assigned to various
electrical components. Likewise, an electrical
component can be protected by several
fuses.
Only replace fuses when the cause of the
problem has been solved. If a newly inserted
fuse blows after a short time, you must have
the electrical system checked by a special-
ised workshop as soon as possible.
Additional information and warnings:
● Working in the engine compartment
››› page 166 . WARNING
The high voltages in the electrical system can
give serious electrical shocks, causing burns
and even death!
● Never touch the electrical wiring of the igni-
tion system.
● Take care not to cause short circuits in the
electrical system. WARNING
Using unsuitable fuses, repairing fuses or
bridging a current circuit without fuses can
cause a fire and serious injury.
● Never use a fuse with a higher value. Only
replace fuses with a fuse of the same amper-
age (same colour and markings) and size.
● Never repair a fuse.
● Never replace a fuse by a metal strip, staple
or similar. CAUTION
● To prevent damage to the vehicle's electric
system, before replacing a fuse always turn
off the ignition, the lights and all electrical
elements and remove the key from the igni-
tion.
● If you replace a fuse with higher-rating
fuse, you could cause damage to another part
of the electrical system.
● Protect the fuse boxes when open to pre-
vent the entry of dust or humidity as they can
damage the electrical system. Note
● One component may have more than one
fuse.
● Several components may run on a single
fuse. Vehicle fuses
