children in the vehicle if they are not restrain-
ed or the restraint system is not appropriate
for their age, size or weight.
●
If you are not wearing a seat belt, or if you
lean forward or to the side while travelling or
assume an incorrect sitting position, there is
a substantially increased risk of injury. This
increased risk of injury will be further in-
creased if you are struck by an inflating air-
bag.
● To reduce the risk of injury from an inflating
airbag, always wear the seat belt properly
››› page 43.
● Alw
ays adjust the front seats properly. Description of airbag system
The airbag system is not a substitute for the
seat belts. The airbag system offers addition-
al protection for the driver and passenger in
combination with the seat belts.
The airbag system comprises the following
modules (as per vehicle equipment):
●
Electronic control unit
● Front airbags for driver and passenger
● Knee airbag for the driver
● Side airbags
● Head airbag ●
Airbag control lamp  on the instrument
panel
● Key-operated switch for front passenger air-
bag
● Control lamp to disconnect/connect the
front airbag.
The airbag system operation is monitored
electronically. The airbag control lamp will il-
luminate for a few seconds every time the ig-
nition is switched on (self-diagnosis).
There is a fault in the system if 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.
The airbag system is not triggered if:
● the ignition is switched off
● there is a minor frontal collision
● there is a minor side collision
● there is a rear-end collision
● the vehicle turns over. WARNING
● The seat belts and airbags can only provide
maximum protection if the occupants are
seated correctly ››› page 38, Sitting position
for vehicle occupants .
● If a fault has occurred in the airbag system,
have the system checked immediately by a
specialised workshop. Otherwise there is a
danger that during a collision, the system
may fail to trigger, or not trigger correctly. Airbag activation
The airbags deploy extremely rapidly, within
thousandths of a second, to provide addi-
tional protection in the event of an accident.
A fine dust may develop when the airbag de-
ploys. This is normal and it is not an indica-
tion of fire in the vehicle.
The airbag system is only ready to function
when the ignition is on.
In special accidents instances, several air-
bags may activate at the same time.
In the event of minor head-on and side colli-
sions, rear-end collisions, overturning or roll-
over of the vehicle, airbags
do not activate.
Activation factors
The conditions that lead to the airbag system
activating in each situation cannot be gener-
alised. Some factors play an important role, »

such as the properties of the object the vehi-
cle hits (hard/soft), angle of impact, vehicle
speed, etc.
Deceleration trajectory is key for airbag acti-
vation.
The control unit analyses the collision trajec-
tory and activates the respective restraint
system.
If the deceleration rate is below the prede-
fined reference value in the control unit the
airbags will not be triggered, even though
the accident may cause extensive damage to
the car.
The following airbags are triggered in
serious head-on collisions
● Driver airbag.
● Front passenger front airbag
● Knee airbag for the driver.
The following airbags are triggered in
serious side-on collisions
● Front side airbag on the side of the acci-
dent.
● Rear side airbag on the side of the acci-
dent.
● Curtain (head) airbag on the side of the ac-
cident. In an accident with airbag activation:
●
the interior lights switch on (if the interior
light switch is in the courtesy light position);
● the hazard warning lights switch on;
● all doors are unlocked;
● the fuel supply to the engine is cut. Airbag overview

Safety
See your technical service to make this ad-
justment.
●
There must be no other persons, animals or
objects between the occupants of the outer
seats and the deployment space of the head-
protection airbags so that the head-protec-
tion airbag can deploy completely without re-
striction and provide the greatest possible
protection. Therefore, sun blinds which have
not been expressly approved for use in your
vehicle may not be attached to the side win-
dows
● The built-in coat hooks should be used only
for lightweight clothing. Do not leave any
heavy or sharp-edged objects in the pockets.
Please, do not hang the clothes on coat hang-
ers.
● The airbags provide protection for just one
accident; replace them once they have de-
ployed.
● Any work on the head-protection airbag
system or removal and installation of the air-
bag components for other repairs (such as re-
moval of the roof lining) should only be per-
formed by a specialised workshop. Other-
wise, faults may occur during the airbag sys-
tem operation.
● Do not attempt to modify components of
the airbag system in any way.
● The side and head airbags are managed
through sensors located in the interior of the
front doors. To ensure the correct operation of
the side and curtain airbags neither the
doors nor the door panels should be modified
in any way (e.g. fitting loudspeakers). If the front door is damaged, the airbag system
may not work correctly. All work carried out
on the front door must be done in a special-
ised workshop.

Airbag system control
The airbag system availability is controlled
electronically, regardless of whether an air-
bag is disabled.
If an airbag was disabled using a diagnostics
system:
● the airbag system warning lamp  illumi-
nates after switching on the ignition for
about 4 seconds, and then flashes for about
12 seconds. If the airbag has been disabled with the air-
bag switch on the side of the dash panel:
●
the airbag control lamp  will illuminate
for about
4 seconds after the ignition is
switched on,
● The airbag is disabled, signalled with the
warning lamp
  which lights up with the
word      placed in the cen-
tre part of the dash panel ››› Fig. 74. WARNING
In the event of a fault in the airbag system,
the airbag may not trigger correctly, may fail
to trigger or may even trigger unexpectedly,
leading to severe or fatal injuries.
● Have the airbag system checked immedi-
ately by a specialised workshop.
● Never mount a child seat in the front pas-
senger seat or remove the mounted child
seat! The front passenger front airbag may
deploy during an accident in spite of the
fault. CAUTION
Always pay attention to any lit control lamps
and to the corresponding descriptions and in-
structions to avoid damage to the vehicle. Note
● Follow the current legislation in your coun-
try regarding the disabling of airbags. ●

The essentials

Operation
Engine cold
If only the diodes in the lower part of the
scale light up, this indicates that the engine
has not yet reached operating temperature.
Avoid high revs and heavy acceleration and
do not make the engine work hard.
Normal temperature
If in normal operations, the diodes light up
until the central zone, it means that the en-
gine has reached operating temperature. At
high outside temperatures and when making
the engine work hard, the diodes may contin-
ue lighting up and reach the upper zone. This
is no cause for concern, provided the control
lamp  does not light up on the instrument
panel digital display.
Heat range
When the diodes light up in the upper area of
the display and the control lamp appears 
on the instrument panel display, the coolant
temperature is excessive ››› page 203. CAUTION
● To ensure a long useful life for the engine,
avoid high revs, driving at high speed and
making the engine work hard for approxi-
mately the first 15 minutes when the engine
is cold. The phase until the engine is warm al-
so depends on the outside temperature. If
necessary, use the engine oil temperature*
››› page 77 as a guide. ●
Additional lights and other accessories in
front of the air inlet reduce the cooling effect
of the coolant. At high outside temperatures
and high engine loads, there is a risk of the
engine overheating.
● The front spoiler also ensures proper distri-
bution of the cooling air when the vehicle is
moving. If the spoiler is damaged this can re-
duce the cooling effect, which could cause
the engine to overheat. Seek specialist assis-
tance. Fuel level - Gas

Problem:
If the vehicle is left parked for a
long time immediately after refuelling, the
natural gas level indicator may not accurately
indicate the same level shown after refuelling
when the vehicle is started up again. This is
not due to a leak in the system, but to a drop
in pressure in the gas tank for technical rea-
sons after a cooling phase just after refuel-
ling.

If the warning lamps and messages are ignor-
ed, the vehicle may stall in traffic, or may
cause accidents and severe injuries.
● Never ignore the warning lamps or text
messages.
● Stop the vehicle safely as soon as possible.
● Park the vehicle away from traffic and en-
sure that there are no highly flammable ma-
terials under the vehicle that could come into
contact with the exhaust system (e.g. dry
grass, fuel).
● A faulty vehicle represents a risk of acci-
dent for the driver and for other road users. If
necessary, switch on the hazard warning
lamps and put out the warning triangle to ad-
vise other drivers.
● Before opening the bonnet, switch off the
engine and allow it to cool. ●
