Airbag system
Control lamp for airbag and seat belt tensioner 
This control lamp monitors the airbag and seat belt tension-
er system.
The control lamp monitors all airbags and seat belt tensioners in the vehi-
cle, including control units and wiring connections.
Monitoring of airbag and belt tensioner system
Both the airbag and belt tensioner systems operation is constantly moni-
tored electronically. Each time the ignition is switched on, the control lamp
 lights for several seconds and the instrument panel display* shows AIR-
BAG/TENSIONER.
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
● lights up or flashes while the vehicle is moving
In the event of a malfunction, the warning lamp remains on continuously. In
addition, depending on the malfunction, a fault message appears in the in-
strument panel display for approx. 10 seconds and a short audible warning
is given. In this event, you should have a specialised workshop check the
system immediately.
If any of the airbags are disabled by a Technical Service, the warning lamp
lights for several seconds more after the verification and will turn off if there
is no fault.WARNING
● If there is a malfunction, the airbag and belt tensioner system cannot
properly perform its protective function.
● If a malfunction occurred, have the system checked immediately by a
specialised workshop. Otherwise, in the event of an accident, the airbag
system and belt tensioners may not be triggered, or may not be triggered
correctly.

Repairs, maintenance and disposal of airbags
The parts of the airbag system are installed in various places in your vehi-
cle. If work is carried out on the airbag system or parts have to be removed
and fitted on the system when performing other repair work, parts of the air-
bag system may be damaged. In the event of an accident this could cause
the airbag to inflate incorrectly or not inflate at all.
The relevant safety requirements must be observed when the vehicle or
components of the airbag are scrapped. Specialised workshops and vehicle
disposal centres are familiar with these requirements.
WARNING
● If repairs are not carried out by a professional, or if the airbags are
used incorrectly, the risk of severe or fatal injuries is increased. The air-
bags may fail to inflate, or could inflate in the wrong circumstances.
● Do not cover or stick anything on the steering wheel hub or the sur-
face of the airbag unit on the passenger side of the dash panel, and do
not obstruct or modify them in any way.
● It is important not to attach any objects such as cup holders or tele-
phone mountings to the surfaces covering the airbag units. 

182Checking and refilling levels
● Water allowed to collect in the fuel filter can cause engine faults.
● Your vehicle is not prepared for use of biofuel (RME) and, therefore, this
fuel must not be used for refuelling or driving. The use of biofuel (RME)
could cause serious damage to the engine or the fuel system. 
Engine compartment
Introduction
Always be aware of the danger of injury and scalding as well as the risk of
accident or fire when working in the engine compartment, e.g. when check-
ing and refilling fluids. Therefore, always observe the warnings and follow
all general safety precautions. The engine compartment of any motor vehi-
cle is a potentially hazardous area .
WARNING
● Never open the bonnet if you see steam, smoke or coolant escaping
from the engine compartment. Risk of scalding! Wait until no steam or
coolant can be seen before opening the bonnet.
● Switch off the engine and remove the key from the ignition.
● Engage neutral in vehicles with manual gearbox and move the selec-
tor lever to position P in vehicles with automatic gearbox.
● Apply the handbrake firmly.
● Wait for the engine to cool down.
● For safety reasons, the bonnet must always be closed when the vehi-
cle is moving. Therefore, after closing the bonnet always check that it is
properly secured.
WARNING (Continued)
● Should you notice that the bonnet is not safely secured when the ve-
hicle is moving, stop the vehicle immediately and close the bonnet prop-
erly. Risk of accident!
● Keep children away from the engine compartment.
● Do not touch hot engine parts. Risk of burns!
● Never spill fluids on hot engine compartments. These fluids can
cause a fire (e.g. antifreeze in coolant).
● Take care not to cause short circuits in the electrical system, especial-
ly when working on the battery.
● Never touch the radiator fan when the engine is hot. The fan may start
running suddenly!
● Do not unscrew the cap on the coolant expansion tank when the en-
gine is hot. The cooling system is under pressure!
● Protect face, hands and arms from any hot steam or hot coolant re-
leased by covering the cap with a large, thick rag when opening the ex-
pansion tank.
● Do not leave any objects, such as cloths and tools, in the engine com-
partment.
● When working underneath the vehicle, secure it so that it cannot roll
away and support it safely on suitable supports. The hydraulic jack is not
sufficient for this purpose. Risk of injuries!
● If any tests have to be performed with the engine running, there is an
extra safety risk from rotating parts, such as the drive belt, alternator
and radiator fan, etc., and from the high-voltage ignition system. You
should also note the following:
–Never touch the electrical wiring of the ignition system.
– Keep away from moving engine parts when wearing jewellery,
loose clothing or long hair. Risk of fatal injuries! All jewellery must be
removed, hair tied back and close-fitting clothing worn.
● Observe the following additional warnings if work on the fuel system
or the electrical system is necessary.
–Always disconnect the battery from the on-board network.
– Do not smoke. 

Fuses and bulbs
Fuses and bulbs Fuses
Introduction
Due to the constant update of vehicles, fuse assignments depending on
equipment and the use of the same fuse for various electrical components,
at the time of printing this manual it is not possible to provide an up-to-date
summary of the electrical components fuse positions. For detailed informa-
tion about the fuse positions, please consult a Technical Service.
In general, a fuse can be assigned to various electrical components. Like-
wise, 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 specialised workshop as soon as possible.
Additional information and warnings:
● Working in the engine compartment ⇒ page 182
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 ignition system.
● Take care not to cause short circuits in the electrical system.
WARNING
Using unsuitable fuses, repairing fuses or bridging a current circuit with-
out 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 amperage (same colour and markings) and size.
● Never repair a fuse.
● Never replace a fuse by a metal strip, staple or similar.
CAUTION
● To avoid damage to the vehicles electric system, before replacing a fuse
turn off the ignition, the lights and all electrical elements and remove the
keys from the ignition.
● 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 avoid the entry of dust or humidity.
Dirt and humidity inside fuse boxes can cause damage to the electrical sys-
tem.
Note
● One single consumer could have more than one fuse.
● Several consumers could run over one single fuse. 
