Airbag system
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.
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 airbag on the side of the accident.
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. 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. Each time the ignition is switched on,
the control lamp
 illuminates for several
seconds (self-diagnosis) and the instrument
panel display* shows AIRBAG/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
● illuminates 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 mes-
sage appears on the instrument panel dis-
play for approximately 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 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. 19Technical specifications
Advice
Operation
Safety

Operation
●
Due care must be taken to avoid any risk of
fire or explosion.
● When parking the vehicle in a closed area
(e.g. in a garage), make sure that there is ad-
equate ventilation, either natural or mechani-
cal, to neutralise the LPG in the event of a
leak. Note
● The values shown in the average fuel con-
sumption and distance to empty indications
on the multifunction display (MFI) 1)
on the in-
strument panel display 2)
are approximate val-
ues only.
● Two different consumption values are given
on the MFI, depending on whether the vehi-
cle is running in gas or petrol mode.
● Please check the fuel level on the fuel level
gauge on the instrument panel ››› page 33.
● If frequent short journeys are made, espe-
cially when the outside temperature is low,
the vehicle will tend to run on petrol more of-
ten than on LPG. Therefore, the petrol tank
may empty before the LPG tank. Engine coolant temperature gauge

tinue driving . You should obtain technical as-
s i

stance. WARNING
When working in the engine compartment, al-
ways observe the safety warnings
››› page 163. CAUTION
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. 1)

Soot accumulation in the diesel
engine particulate filter  If the control lamp
 lights up you should
help the filter clean itself by driving in the ap-
propriate manner.
To do this, drive about 15 minutes in fourth
or fifth gear (automatic gearbox: S gear
range) at a minimum speed of 60 km/h (37 mph), with the engine running at approxi-
mately 2,000 rpm. In this way, the soot build
up in the filter is burned. When cleaning is
successful, the control lamp turns off.
If the lamp
 does not turn off, or the three
l amp

s turn on (particulate filter , fault in
the emission control system  and glow
plugs ), drive the vehicle to a specialised
workshop and have the fault repaired at the
earliest opportunity. WARNING
● Always drive according to the road weather
conditions, the terrain and traffic. Driving rec-
ommendations should never lead to illegal
manoeuvres in surrounding traffic.
● The diesel engine particulate filter may
reach extremely high temperatures; in this
case the vehicle should be parked so that it
does not enter into contact with highly flam-
mable materials underneath the vehicle. Oth-
erwise there is a risk of fire. Anti-lock brake system (ABS)* 
The warning lamp  lights up for a few sec-
onds when the ignition is switched on. It
goes out again after the system has run
through an automatic test sequence.

Operation
There is a fault in the ABS if:
● The warning lamp 
does not light up
when the ignition i
s switched on.
● The control lamp does not go out again af-
ter a few seconds.
● The control lamp lights up when the vehicle
is moving.
The vehicle can still be braked in the normal
way, without the ABS function. Take the vehi-
cle to a specialised workshop as soon as
possible. For further information on the ABS
see the ››› page 136
.
If a fault occurs in the ABS, the ESC* control
lamp will also light up.
Brake system fault
If the ABS warning lamp  lights up together
with the brake warning lamp , there is a
fault in the ABS function and in the brake
system ››› .
WARNING
● Before opening the bonnet, read and ob-
serve the warnings ››› page 163, Working in
the engine compartment.
● If the br

ake system warning lamp  should
light up together with the ABS warning lamp
, stop the vehicle immediately and check the brake fluid level in the reservoir
››› page 172, Brake fluid. If the brake fluid
l ev

el has dropped below the “MIN” mark you
must not drive on. Risk of accident. Obtain
technical assistance.
● If the brake fluid level is correct, the fault in
the brake system may have been caused by a
failure of the ABS system. This could cause
the rear wheels to lock quickly when you
brake. This could cause the rear to break
away. Risk of skidding. Stop the vehicle and
seek technical assistance. Washer fluid* 
This warning lamp lights up to indicate that
the windscreen washer level is very low.

● Before opening the bonnet, read and ob-
serve the warnings on ››› page 163.
● If the brake warning lamp does not go out,
or if it lights up when driving, the brake fluid
level in the reservoir ››› page 172, Brake fluid
is too low. Risk of accident. Stop the vehicle
and do not drive on. Obtain technical assis-
tance.
● If the brake warning lamp lights up  to-
gether with the ABS lamp  this could be
due to an ABS fault. This could cause the rear wheels to lock quickly when you brake. This
could cause the rear to break away. Risk of
skidding. Stop the vehicle and seek technical
assistance.

Cruise speed (cruise control)*  The warning lamp 
comes on when the
c
ruise control system is switched on. For fur-
ther information on the cruise control system,
see ››› page 142
.
Indicator for open doors or boot*  This warning lamp lights up if one of the
doors is open.
The warning light
 should go off when all
the doors are closed correctly.
The system also works when the ignition is
switched off. It should disappear approxi-
mately 15 seconds after the vehicle has been
locked.
Electromechanical steering*  For vehicles with power steering, the level of
steering assistance depends on the vehicle's
speed and on the steering angle.
The warning lamp should light up for a few
seconds when the ignition is switched on. It
should go out once the engine is started.
If the battery is disconnected, the indicator
remains lit, even with the engine running. The warning light only goes off after a dis-
tance of approx. 50 m.
There is a fault in the electromechanical
steering system if the lamp does not go out
or lights up while the vehicle is in motion.
The warning lamp may appear in two differ-
ent colours to indicate faults. If the light is
yellow, it indicates a minor fault. If the light is
red, seek assistance from a specialised work-
shop immediately, as the power steering is
not working; in this case you should not keep
driving. Stop the vehicle and seek technical
assistance. The power steering does not work
if the battery is flat or if the engine is off (e.g.
for towing). You should take into account that
you will need considerably more power than
normal to steer the vehicle if the power steer-
ing is not working correctly or at all.
For those vehicles fitted with ESC*, the
“Steering manoeuvre recommendation”
››› page 134 function is included.
