8Safe driving
you and your passengers can achieve the greatest possible benefit from the
safety equipment fitted. This manual includes important warnings that you
and your passengers should note in order to reduce the risk of injury.
Safety is everyone's business! 
Before setting off
The driver is always responsible for the safety of the passen-
gers and the safe operation of the vehicle.
For your own safety and the safety of your passengers, always note
the following points before every trip:
– Make sure that the vehicle's lights and turn signals are working
properly.
– Check tyre pressure.
– Ensure that all windows provide a clear and good view of the
surroundings.
– Ensure that all luggage is correctly secured ⇒ page 16.
– Make sure that no objects can interfere with the pedals.
– Adjust front seat, head restraint and rear vision mirrors properly
according to your size.
– Ensure that the passenger in the central rear seat always has
the head restraint in the correct position for use.
– Instruct passengers to adjust the head restraints according to
their height. –
Protect children with appropriate child seats and properly ap-
plied seat belts ⇒ page 42.
– Assume the correct sitting position. Instruct your passengers al-
so to assume a proper sitting position. ⇒ page 10.
– Fasten your seat belt securely. Instruct your passengers also to
fasten their seat belts properly. ⇒ page 18. 
What affects driving safety?
Driving safety is largely determined by your driving style
and the personal behaviour of all vehicle occupants.
As a driver, you are responsible for yourself and your passengers.
When your concentration or driving safety is affected by any cir-
cumstance, you endanger yourself as well as others on the road
⇒ 
, for this reason:
– Always pay attention to traffic and do not get distracted by pas-
sengers or telephone calls.
– Never drive when your driving ability is impaired (e.g. by medi-
cation, alcohol, drugs).
– Observe traffic laws and speed limits.
– Always reduce your speed as appropriate for road, traffic and
weather conditions.
– When travelling long distances, take breaks regularly - at least
every two hours.
– If possible, avoid driving when you are tired or stressed. 

Seat belts
The control lamp  in the instrument panel lights up 1)
if the driver or pas-
senger seat belt is not fastened 1)
when the ignition is switched on. More-
over, an audible warning 1)
is heard on exceeding 25 km/h (15 mph). This
acoustic signal stops when the seat belt is fastened.
The warning lamp*  is switched off if the driver seat belt is fastened while
the ignition is switched on. 

Airbag system
Monitoring of airbag and belt tensioner system
Both the airbag and belt tensioner systems operation is constantly moni-
tored electronically. The control lamp  will light up for a few seconds every
time the ignition is switched 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
● lights up or flashes while the vehicle is moving
In the event of a malfunction, the warning lamp remains on continuously.
Have the airbag system inspected immediately by a specialised workshop.
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.
● To clean the steering wheel or dash panel, you may use only a dry or a
water-moistened cloth. Never clean the dash panel and the airbag mod-
ule surface with cleaners containing solvents. Solvents cause the surface
to become porous. If the airbag triggered, plastic parts could become de-
tached and cause injuries.
● Never attempt to repair, adjust, remove or install parts of the airbag
system.
● Any work on the airbag system or removal and installation of the air-
bag components for other repairs (such as repairs to the steering wheel)
should be performed only by a specialised workshop. Specialised work-
shops have the necessary tools, repair information and qualified person-
nel.
● We strongly recommend you to go to a specialised workshop for all
work on the airbag system.
● Never attempt to alter the front bumper or the body.
● The airbags provide protection for just one accident; replace them
once they have deployed. 

70Cockpit
There is a fault in the ABS if:
● The control lamp  does not light up when the ignition is switched on.
● The control lamp does not go out again after 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 vehicle to a specialised workshop as soon as possible. For further
information on the ABS go to ⇒ page 163.
If there is a fault in the ABS, the ESC* and the tyre pressure control lamp will
also light up.
Brake system fault
If the ABS warning lamp  lights up together with the brake warning lamp
 , this indicates not only a fault in the ABS function, but also a possible
fault in the brake system ⇒ 
.
WARNING
● Before opening the bonnet, read and observe the warnings on
⇒ page 193, Working in the engine compartment.
● If the brake 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 206, Brake fluid. If the brake fluid lev-
el has dropped below the “MIN” mark you must not drive on. Risk of acci-
dent. 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 assis-
tance.
 Differential lock fault (EDL)*
The EDL operates along with the ABS in vehicles equipped
with the Electronic Stability Control (ESC)*
A malfunction in the EDL is indicated by the ABS control lamp . Take the
vehicle to a specialised workshop as soon as possible. For further informa-
tion on the EDL see ⇒ page 165, Electronic differential lock (EDL)*. 
Traction control system (ASR)*  / 
The traction control system prevents the driven wheels from
spinning when the vehicle is accelerating
There are two warning lamps for the traction control system:  and . Both
warning lamps light up together when the ignition is switched on and
should turn off after approximately 2 seconds. This is the time taken for the
function check.
The  lamp has the following function:
● It flashes when the ASR is working if the vehicle is moving.
If the system is deactivated or if it has any fault, the warning lamp will re-
main lit. The warning lamp will also light up if a fault should occur in the
ABS because the ASR operates in conjunction with the ABS. For further in-
formation, see ⇒  page 162, Brakes
The  lamp provides information about the disconnection status of the
system:
● It stays lit when the ASR is disconnected when pressing the  switch.
By pressing it again, the ASR function is reactivated and the warning lamp
switched off. 
