8Safe driving
passengers are sitting in a correct position and use this equipment proper-
ly.
Therefore, information is provided about why this equipment is so impor-
tant, how it protects you, what you have to consider when using it and how
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 starting every trip
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.
– Make sure all luggage is secured ⇒ page 17.
– 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 passengers in the rear seats always have the
head restraints in the in-use position ⇒ page 15
– Instruct passengers to adjust the head restraints according to
their height.
– Protect children with appropriate child seats and properly ap-
plied seat belts ⇒ page 48.
– 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 20. 
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. 

18Safe driving
WARNING
● Loose luggage and other objects in the luggage compartment could
cause serious injuries.
● Always stow objects in the luggage compartment and secure them on
the fastening rings.
● Use suitable straps to secure heavy objects.
● During sudden manoeuvres or accidents, loose objects can be thrown
forward, injuring vehicle occupants or passers-by. This increased risk of
injury will be further increased if a loose object is struck by an inflating
airbag. If this happens, objects can be transformed into “missiles”. Risk
of fatal injury.
● Please note that the centre of gravity may shift when transporting
heavy objects; this may affect vehicle handling and lead to an accident.
Therefore, it is essential to adjust your speed and driving style accord-
ingly, to avoid accidents.
● Never exceed the allowed axle weights or allowed maximum weight.
If the allowed axle load or the allowed total weight is exceeded, the driv-
ing characteristics of the vehicle may change, leading to accidents, inju-
ries and damage to the vehicle.
● Never leave your vehicle unattended, especially when the rear lid is
open. Children could climb into the luggage compartment, closing the
door behind them; they will be trapped and run the risk of death.
● Never allow children to play in or around the vehicle. Close and lock
all the doors and rear lid when you leave the vehicle. Before you lock the
vehicle, make sure that there are no adults or children in the vehicle.
● Never transport passengers in the luggage compartment. All vehicle
occupants must have their seat belt fastened ⇒ page 20.Note
● Air circulation in the vehicle helps reduce fogging of the windows. Used
air escapes through ventilation slits in the side trim of the luggage compart-
ment. Ensure that the ventilation slits are never covered.
● Straps for securing the load to the fastening rings are commercially
available. 
Fastening rings*
There can be four fastening rings in the luggage compart-
ment for fastening luggage and other objects.
– Always use suitable and undamaged straps to secure luggage
and other objects to the fastening rings ⇒ 
in Loading the lug-
gage compartment on page 18.
Bear in mind that in the case of a collision or accident, even small and light
objects that are not firmly fixed can be projected at the occupants causing
injury.
Example: An object weighing 4.5 kg is lying unsecured in the vehicle. Dur-
ing a frontal collision at a speed of 50 km/h (30 mph), this object generates
a force corresponding to 20 times its weight. That means that the effective
weight of the object increases to about 90 kg. You can imagine the severity
of the injuries which might be sustained if this object strikes an occupant as
it flies through the interior of the vehicle. This increased risk of injury will be
further increased if a loose object is struck by an inflating airbag. 

21
Seat belts
– Instruct your passengers to fasten their seat belts properly be-
fore driving off.
– Protect children by using a child seat according to the child's
height and weight.
After the ignition has been switched on, the warning lamp  on the instru-
ment panel lights up 1)
if the driver has not fastened his/her seat belt. An
audible warning is heard if the vehicle is driven at more than 30 km/h (18
mph).
The warning lamp*  is switched off if the driver seat belt is fastened while
the ignition is switched on.
Indication of the state of the seat belts in the rear seats.
The seat belt status display ⇒ Fig. 7 on the instrument panel informs the
driver, when the ignition is switched on, whether the passengers in the rear
seats have fastened their seat belts. The  symbol indicates that the pas-
senger in this seat has fastened “his or her” seat belt.
When a seat belt in the rear seats is fastened or unfastened, the seat belt
status is displayed for approx. 30 seconds. The indication can be hidden by
pressing the 0.0/SET
button on the dash panel.
The seat belt status flashes for a maximum of 30 seconds when a seat belt
in the rear seats is unfastened while the vehicle is in motion. An audible
warning will also be heard if the vehicle is travelling at over 25 km/h
(15 mph). 

Seat belts
– Guide the belt back by hand so that it rolls up easily and the
trim is not damaged.
WARNING
Never unbuckle a seat belt while the vehicle is in motion. If you do, you
increase the risk of sustaining severe or fatal injuries.

Incorrectly fastened seat belts
Incorrectly worn seat belts can cause severe or even mortal
injuries. Seat belts can provide optimal protection only if the belt web is
properly worn. The seat belts must be fastened exactly in the order
described in this chapter. An incorrect sitting position impairs sub-
stantially the protection a seat belt offers and can lead to severe or
fatal injuries. The risk of severe or fatal injuries is especially in-
creased when a deploying airbag strikes a vehicle occupant who
has assumed an incorrect sitting position. As the driver, you are re-
sponsible for yourself and all passengers, especially children.
Therefore:
– Never allow anyone to wear the seat belt incorrectly while the
vehicle is moving ⇒ 
.
WARNING
● An incorrectly worn seat belt increases the risk of severe injuries.
● Before every trip, instruct your passengers to adjust their seat belts
properly and to wear them for the whole journey.
● Read and always observe information and warnings concerning the
use of seat belts ⇒ page 24.

Seat belt tensioners
Function of the seat belt tensioner
During a frontal collision, the seat belts on the front seats
are retracted automatically. The seat belts for the occupants in the front seats are equipped with belt
tensioners. Sensors will only trigger the belt tensioners during severe head-
on, lateral and rear collisions, and only if the seat belt is actually being
worn. This retracts and tightens the seat belts, reducing the forward motion
of the occupants.
The seat belt tensioner can be triggered only once.
The seat belt tensioners will not be triggered in the event of a light frontal,
side or rear collision, if the vehicle overturns or in situations where no large
forces act on the front, side or rear of the vehicle. 

⇒ 
.
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 immediately by a specialised work-
shop.
● Never mount a child seat in the front passenger 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 de-
scriptions and instructions to avoid damage to the vehicle. 
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. 

40Airbag system
Side airbags*
Description of side airbags
The airbag system is not a substitute for the seat belts.
Fig. 25 Side airbag in
driver seat
The side airbags are located in the backrest cushions of the driver seat
⇒  Fig. 25 and the front passenger seat as well as in the rear seats*. The lo-
cations are identified by the text “AIRBAG” in the upper region of the backr-
ests.
Together with the seat belts, the side airbag system gives the front seat oc-
cupants additional protection for the upper body in the event of a severe
side collision ⇒ page 42, Safety notes on the operation of the side airbag
system.
In a side collision, the side airbags reduce the risk of injury to passengers
on the front seats to the areas of the body facing the impact. In addition to
their normal function of protecting the occupants in a collision, the seat
belts also hold the passengers in the front seats and the outer rear seats in
a position where the side airbags can provide maximum protection. 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. 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 20, Brief introduction.
The side airbag system will not be triggered if:
● the ignition is switched off
● there is a minor side collision
● there is a frontal collision
● there is a rear-end collision
● the vehicle turns over
The main parts of the airbag system are:
● an electronic control and monitoring system (control unit)
● the side airbags in the sides of the backrests of the front and rear seats
● a control lamp  in the dash panel
The airbag system operation is monitored electronically. The airbag control
lamp will light up for approx. 4 seconds every time the ignition is switched
on (self-diagnosis).
WARNING
● In a side-on collision the side airbags will not work if the sensors do
not correctly measure the pressure increase on the interior of the doors,
due to air escaping through the areas with holes or openings in the door
panel.
● Never drive the vehicle if the interior panels have been removed.
● Never drive if the interior door panels have been removed or if the
panels have not been correctly fitted. 

42Airbag system
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 side airbag system
If airbags are used correctly, they can considerably reduce
the risk of injury in side impact collisions.
WARNING
● If you do not wear a seat belt, if you lean forward, or are not seated
correctly while the vehicle is in motion, you are at a greater risk of injury
if the side airbag system is triggered in an accident.
● In order for the side airbags to provide their maximum protection, the
prescribed sitting position must always be maintained with seat belts
fastened while travelling.
● Occupants of the outer seats must never carry any objects or pets in
the deployment space between them and the airbags, or allow children
or other passengers to travel in this position. It is also important not to
attach any accessories (such as cup holders) to the doors. This would im-
pair the protection offered by the side airbags.
● The built-in coat hooks should be used only for lightweight clothing.
Do not leave any heavy or sharp-edged objects in the pockets.
● Great forces, such as hard blows or kicks, must not be exerted upon
the backrest bolster because the system may be damaged. In this case,
the side airbags would not be triggered.
WARNING (Continued)
● Under no circumstances should protective covers be fitted over seats
with side airbags unless the covers have been approved for use in your
vehicle. Because the airbag deploys from the side of the backrest, the
use of conventional seat covers would obstruct the side airbag, seriously
reducing the airbag's effectiveness.
● Any damage to the original seat upholstery or around the seams of
the side airbag units must be repaired immediately by a specialised
workshop.
● The airbags provide protection for just one accident; replace them
once they have deployed.
● When children assume an incorrect sitting position, they expose
themselves to an increased risk of injury in the event of an accident. This
is particularly the case if the child is travelling on the front passenger
seat and the airbag system is triggered in an accident; this could have
critical consequences including serious injury or death ⇒ page 48.
● Any work on the side airbag system or removal and installation of the
airbag components for other repairs (such as removal of the front seat)
should only be performed by a specialised workshop. Otherwise, faults
may occur during the airbag system 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 head airbags neither the doors nor the door panels should be modi-
fied 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 specialised workshop.
