Te c h n i c a l D a t a
The front airbag system will not be triggered if:
•
if the ignition is switched off,
•
during a minor frontal collision,
•
during a side collision,
•
during a rear-end collision,
•
or if the vehicle rolls.
WARNING
•
The seat belts and airbags can only provide maximum protection if the
occupants are seated correctly ⇒page 10, “Proper sitting position for
occupants”.
•
If a fault should occur in the airbag system, have the system checked
immediately by a qualified workshop. Otherwise there is a danger that
during a frontal collision, the system may fail to trigger, or not trigger
correctly.
Function of front airbags
Inflated airbags reduce the risk of head or chest injury.The airbag system is designed so that the airbags for the driver and front
passenger are triggered in a severe frontal collision.
In certain types of accident the front, curtain and side airbags may be trig-
gered together.
When the system is triggered, the airbags fill with a propellant gas and
deploy in front of the driver and front passenger ⇒fig. 19 . The fully deployed
airbags cushion the forward movement of the front occupants and help to
reduce the risk of injury to the head and the upper part of the body.
The special design of the airbag allows the controlled escape of the propel-
lant gas when an occupant puts pressure on the bag. Thus, the head and
chest are surrounded and protected by the airbag. Once the impact has been
absorbed, the airbag deflates sufficiently for the front occupants to see
forward.

Function of side airbags
Inflated airbags can reduce the risk of head or chest injury in
many side impact collisions.In some side collisions the side airbag is triggered on the impact side of the
vehicle ⇒fig. 22.
In certain types of accident the front, curtain and side airbags may be trig-
gered together.
When the system is triggered, the airbag is filled with propellant gas.
In order to provide the desired extra protection in an accident, the airbags
have to deploy extremely rapidly (within fractions of a second). A fine dust
may develop when the airbag deploys. This is normal and is no indication
that there was a fire in the vehicle.
The fully deployed airbags cushion the movement of the occupants of the
front seats and the outer rear seats and help to reduce the risk of injury to the
upper body. The special design of the airbag allows the controlled escape of the propel-
lant gas when an occupant puts pressure on the bag. Thus, the head and
chest are surrounded and protected by the airbag.

WARNING
If a fault should occur in the airbag system, have the system checked imme-
diately by a qualified workshop. Otherwise there is a danger that during a
collision, the system may fail to trigger, or not trigger correctly.Function of curtain airbags
Fully inflated airbags reduce the ri sk of head or chest injury in
a side collision.
During some side collisions the curtain airbag is triggered on the impact side
of the vehicle ⇒ fig. 24.
In certain types of accident the front, side and curtain airbags may be trig-
gered together.
When the system is triggered, the airbag is filled with propellant gas. In the
process, the curtain bag covers the side windows and door pillars.
In order to provide the desired extra protection in an accident, the airbags
have to deploy extremely rapidly (within fractions of a second). A fine dust
may develop when the airbag deploys. This is normal and is no indication
that there was a fire in the vehicle.
The fully deployed airbags cushion the movement of the front occupants and
help to reduce the risk of injury to the upper body.
The special design of the airbag allows the controlled escape of the propel-
lant gas when an occupant puts pressure on the bag. Thus, the head and
chest are surrounded and protected by the airbag.Safety notes on the operation of the curtain airbag system
If you use airbags correctly, they can considerably reduce the
risk of injury in many kinds of accident.
WARNING
•
In order for the side airbags to provide their maximum protection, the
prescribed sitting position must alwa ys be maintained with seat belts
fastened while travelling.
•
For safety reasons, the head air bag must be disconnected in those
vehicles fitted with a passenger compartment separation screen. See an
Authorised Service Centre to make this adjustment.

Checking and refilling levels
204•
If you decide to use biodiesel in your vehicle, please use only RME fuel
which is DIN E 14,214 compliant.
•
If you use biodiesel that does not m eet the required standard, the fuel
filter could become clogged.Note
•
In case of low exterior temperatures and a fuel biodiesel percentage of
higher than 50%, an increase in gas em ission may occur during operation of
the independent heating.
•
The fuel filter may become clogged when fuel is changed to biodiesel. For
this reason, we recommend that, about every 300 or 400 km, following a fuel
change, also change the fuel filter. Also note the instructions in the Inspec-
tion and Maintenance plan.
•
If the vehicle is to remain parked for more than about two weeks, we
recommend filling the fuel tank with biodiesel and driving about 50 km in
order to avoid damage to the injection system.
Winter driving
Diesel can thicken in winter.Winter-grade diesel
When using “summer-grade diesel fuel”, difficulties may be experienced at
sub-zero temperatures because the fuel thickens due to wax separation. For
this reason, “winter-grade diesel fuel” is available in some countries during
the cold months. It can be used at temperatures as low as -22°C.
In countries with different climatic conditions the diesel fuel sold generally
has different temperature characteristics. Check with an Authorised Service
Centre or filling stations in the country concerned regarding the type of diesel
fuels available. Filter pre-heater
Your vehicle is fitted with a fuel filter pre-heater, making it well equipped for
operation in winter. This ensures that the fuel system remains operational to
approx. -24°C, provided you use winter-grade diesel which is safe to -15°C.
However, if the fuel has waxed to such an extent that the engine will not start
at temperatures of under -24°C, simply place the vehicle in a warm place for
a while.
Caution
Do not mix fuel additives (“thinners”, or similar additives) with diesel fuel.Working in the engine compartmentSafety instructions on working in the engine compartment
Any work carried out in the engine compartment or on the
engine must be carried out cautiously.Before starting any work on the engine or in the engine compart-
ment:
1. Switch off the engine and remove the key from the ignition.
2. Apply the handbrake.
3. Move the gear stick to neutral or the selector lever to position P.
4. Wait for the engine to cool down.
5. Keep children away from the vehicle.
