8Safe driving
Therefore, this chapter explains why these safety features are so important,
how they can protect you, what you need to remember when using them
and how you and your passengers can gain the most benefit from them.
There are also a number of important safety warnings that you and your
passengers should always observe in order to minimise the risk of injury.
Safety is everyone's responsibility! 
Before setting off
The driver is responsible for the safety of the passengers
and the safe operation of the vehicle at all times. For your own safety and the safety of your passengers, always note
the following points before setting off:
– Make sure that all lights and indicators are working properly.
– Check tyre pressure.
– Make sure that all windows are clean and give good visibility to
the outside.
– Secure all luggage and other items carefully ⇒ page 16.
– Make sure that no objects can interfere with the pedals.
– Adjust the front seat, head restraint and mirrors correctly.
– Make sure that the head restraints for all passengers are adjus-
ted to the correct position.
– Make sure that children are protected with suitable safety seats
and properly worn seat belts ⇒ page 47. –
Sit in a correct position. Inform your passengers as to how they
should sit ⇒ page 10.
– Fasten your seat belt correctly. Make sure that your passengers
do the same ⇒ page 19. 
What affects safe driving?
Safety on the road is directly related to how you drive, and
can also be affected by the passengers in the vehicle. The driver is responsible for the safety of the vehicle and all its oc-
cupants. If your ability to drive is impaired in any way, you endan-
ger yourself and other road users ⇒ 
. Therefore:
– Do not let yourself be distracted by passengers or by using a
mobile phone, etc.
– Never drive when your driving ability is impaired (by medica-
tion, alcohol, drugs, etc.).
– Obey all traffic regulations and speed limits and always main-
tain a safe distance to the vehicle in front.
– Always adjust your speed to suit the road, traffic and weather
conditions.
– Take frequent breaks on long trips. Do not drive for more than
two hours without a stop.
– If possible, avoid driving when you are tired or stressed. 

Airbag system
Warning lamp for airbag and seat belt tensioner 
This warning lamp monitors the airbag and seat belt ten-
sioner system.
The warning 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. The warning lamp  will light every time the ignition is
switched on until you attach your seatbelt.
The system must be checked when the warning lamp  :
● does not light up when 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 system inspected immediately by a specialised workshop.
If any of the airbags are de-activated by the Technical Service, the indicator
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. 

Airbag system
Front airbags
Description of front airbags
The airbag system is not a substitute for the seat belts.
Fig. 17 Driver airbag in
the steering wheel and
knee airbag in the dash
panel
Fig. 18 Front passenger
airbag located in dash
panel The front airbag for the driver is located in the steering wheel
⇒ Fig. 17 and
the airbag for the front passenger is located in the dash panel ⇒ Fig. 18. Air-
bags are identified by the word “AIRBAG”. On the driver side, the knee air-
bag* is found in the footwell lining, under the instrument panel.
In conjunction with the seat belts, the front airbag system gives the front
occupants additional protection for the head and chest in the event of a se-
vere frontal collision ⇒ page 36, Safety notes on the front airbag system.
In addition to their normal function of restraining the occupants, the seat
belts also hold the driver and front passenger in a position where the air-
bags can provide maximum protection in a frontal collision.
The airbag system is not a substitute for seat belts, but it is an integral part
of the vehicle's overall passive safety system. Please bear in mind that the
airbag system can only work effectively when the occupants are wearing
their seat belts correctly and have adjusted the head restraints properly.
Therefore, it is most important to wear the seat belts at all times, not only
because this is required by law in most countries, but also for your safety
⇒ page 19, Brief introduction.
The main parts of the front airbag system are:
● an electronic control and monitoring system (control unit)
● the two front airbags (airbag with gas generator) for the driver and front
passenger,
● a knee airbag* for the driver,
● a warning lamp  on the instrument panel ⇒ page 31
The airbag system operation is monitored electronically. The airbag warning
lamp will light up for a few seconds every time the ignition is switched on
(self-diagnosis).
There is a fault in the system if the warning lamp :
● does not light up when the ignition is switched on ⇒ page 31
● turns off and then lights up again after the ignition is switched on,
● lights up or flashes while the vehicle is moving. 

Airbag system
that the airbag system can only help to protect you if you are wearing your
seat belt and wearing it properly.
Remember too that airbags will deploy only once and only in certain kinds
of accidents - your seat belts are always there to offer protection in those
accidents in which airbags are not supposed to deploy or when they have
already deployed, for example when your vehicle strikes or is struck by an-
other after the first collision.
This is just one of the reasons why an airbag is not a substitute for the seat
belt. The airbag system works most effectively when used with the seat
belts. Therefore, always wear your seat belts correctly.
It is important to remember that while the airbag system is designed to re-
duce the possibility of serious injuries, other injuries, for example, swelling,
bruising, and minor abrasions can also be associated with airbags.
The knee airbag system basically consists of:
● The electronic control module
● One inflatable airbag (airbag and gas generator) for the driver
● An airbag indicator light on the instrument panel
The knee airbag system will not be triggered:
● if the ignition is switched off
● in frontal collisions when the deceleration measured by the control unit
is too low
● in side collisions
● in rear-end collisions
● in rollovers
● in the event of a system malfunction (hazard warning lights/turn signals
illuminated) ⇒ page 67.
WARNING
● Seat belts and the airbag system can only provide protection when
occupants are in the proper seating position.
● If the airbag indicator light comes on when the vehicle is being used,
have the system inspected immediately by your Technical Service. The
airbag may not work properly when the vehicle acceleration in a side col-
lision is high enough to deploy the airbag. See also ⇒ page 67.

How knee airbags work
The risk of injury to the leg area is reduced by fully deployed
knee airbags.
Fig. 22 Inflated airbags
protect in a frontal colli-
sion.
The knee airbag system has been designed so that the airbag for the driver
is deployed in certain but not all frontal collisions.
If the front airbag deploys, the knee airbag also deploys in severe frontal
collisions. 

Cockpit
Speedometer with odometer
The speedometer indicates the speed of the vehicle and the
distance travelled.
Fig. 42 Detailed view of
the instrument panel:
Odometer
The distance is normally stated in kilometres (km). On some models, how-
ever, the odometer will show “miles”.
Lower odometer
The lower odometer records the vehicle's total mileage.
Upper odometer (trip recorder)
The upper odometer shows the distance that has been travelled since the
trip recorder was last reset. It is used to measure short trips. The last digit of
the trip recorder indicates distances of 100 metres or tenths of a mile. The
upper odometer can be reset to zero by pressing the reset button ⇒ Fig. 42.
Fault display
If there is a fault in the instrument panel, the letters DEF will appear perma-
nently in the trip recorder display. Please have the fault repaired as soon as
possible. Electronic immobiliser
The vehicle key data is consulted when the ignition is switched on.
If an uncoded key is used, the message
SAFE will appear in the trip recorder
display. The vehicle can no longer be started if that happens. 
Fuel reserve
The display only works when the ignition is switched on.
When the needle reaches the reserve zone, the symbol  lights up in the
instrument panel display ⇒ page 83. At this point there are still about 8 to
10 litres of fuel left in the tank. This is your reminder to fill up soon.
You can consult the tank capacity of your vehicle in the ⇒ page 312, Di-
mensions and capacities section.
CAUTION
Never run the tank completely dry. If there is an irregular fuel supply, misfir-
ing can occur. This means that fuel could reach the exhaust system without
burning. This may lead to the catalytic converter reheating and being dam-
aged. 
