64Ensuring you are correctly and safely seated
Automatic belt retainer, belt tensioner, belt tension limiter
Seat belts are part of the vehicle safety concept ⇒ page 65 and consist of
the following important functions:
Automatic belt retainer
Every seat belt is equipped with an automatic belt retainer on the shoulder
belt. If the belt is pulled slowly or during normal driving, the system allows
for total freedom of movement on the shoulder belt. However, during sud-
den braking, during travel in mountains or bends and during acceleration,
the automatic belt retainer on the seat belt is locked is pulled quickly.
Belt tensioners
The seat belts for the occupants in the front seats are equipped with belt
tensioners.
Sensors will trigger the belt tensioners during severe head-on, lateral and
rear collisions and retract and tighten the seat belts. If the seat belt is
loose, it is retracted to reduce the forwards movement of occupants or
movement in the direction of the collision. The belt tensioner works in com-
bination with the airbag system. The belt tensioner will not be triggered in
the event of the vehicle overturning if the side airbags are not deployed.
If the belt tensioner is triggered, a fine dust is produced. This is normal and
it is not an indication of fire in the vehicle.
Belt tension limiter
The belt tension limiter reduces the force of the seat belt on the body in the
event of an accident.
Note
The relevant safety requirements must be observed when the vehicle or
components of the system are scrapped. These requirements are known to
specialised workshops ⇒ page 64. Service and disposal of belt tensioners
If you work on the belt tensioners or remove and install other parts of the
vehicle when performing other repair work, the seat belt may be damaged.
The consequence may be that, in the event of an accident, the belt tension-
ers function incorrectly or not at all.
So that the effectiveness of the belt tensioner is not reduced and that re-
moved parts do not cause any injuries or environmental pollution, regula-
tions must be observed. These requirements are known to specialised work-
shops.
WARNING
Improper handling and homemade repairs of seat belts, automatic belt
retainers and tension devices increase the risk of sustaining severe or fa-
tal injuries. The belt tensioner may fail to trigger or may trigger in the
wrong circumstances.
● Never attempt to repair, adjust or remove or install parts of the belt
tensioners or seat belts. Any work must be performed by a specialised
workshop only ⇒ page 222.
● Belt tensioners and automatic belt retainers cannot be repaired and
must be replaced.
For the sake of the environment
Airbag modules and belt tensioners may contain perchlorate. Observe the
legal requirements for their disposal. 

Transporting
Driving tips Introduction
Always transport heavy loads in the luggage compartment and place the
seat backs in a vertical position. Never overload the vehicle. Both the carry-
ing capacity as well as the distribution of the load in the vehicle have ef-
fects on the driving behaviour and braking ability ⇒ 
.
Additional information and warnings:
● Rear lid ⇒ page 39
● To lower the front passenger seat back ⇒ page 54
● Light ⇒ page 82
● Luggage compartment ⇒ page 98
● Roof carrier ⇒ page 104
● Wheels and tyres ⇒ page 210
WARNING
Unsecured or incorrectly secured objects can cause serious injury in case
of a sudden manoeuvring or breaking or in case of an accident. This is es-
pecially true when objects are struck by a detonating airbag and fired
through the vehicle interior. To reduce the risks, please note the follow-
ing:
● Secure all objects in the vehicle. Always keep equipment and heavy
objects in the luggage compartment.
WARNING (Continued)
● Always secure objects with suitable rope or slings so that they cannot
enter the deployment areas around the frontal or side airbags in case of
sudden braking or an accident.
● Always ensure that objects inside the vehicle cannot move into the
deployment area of the bags while driving.
● While driving, always keep object compartments closed.
● Remove all objects from the front passenger seat when this is fol-
lowed down. When the seat backrest is folded down, it presses on small
and light objects and these are detected by the weight sensor on the
seat; this sends false information to the airbag control unit.
● While the backrest of the front passenger seat is folded, the frontal
airbag must remain disconnected and the PASSENGER AIRBAG OFF 
light on.
● Objects secured in the vehicle should never be placed in such a way
as to make passengers sit in an incorrect position.
● If secured objects occupy a seat then this should not be occupied or
used by anybody.
WARNING
The driving behaviour and braking ability change when transporting
heavy and large objects.
● Adjust your speed and driving style to visibility, road, traffic and
weather conditions.
● Accelerate gently and carefully.
● Avoid sudden braking and manoeuvres.
● Brake early.

124Starting, changing gears, parking
Changing gear
Introduction
When reverse gear is engaged and the ignition is switched on the following
takes place:
● Reverse lights light up.
● The rear wiper blade performs one movement when the windscreen wip-
er is activated.
● If necessary, connect the parking distance warning system.
Additional information and warnings:
● Detail of the centre console ⇒ page 12
● Instruments ⇒ page 17
● Braking, stopping and parking ⇒  page 134
● Parking sensor system ⇒  page 149
● Electronic power control and exhaust gases purification system
⇒ page 237
● Emergency locking and unlocking ⇒ page 244
WARNING
Rapid acceleration can cause loss of traction and skidding, especially on
slippery ground. This could cause loss of control of the vehicle resulting
in an accident and considerable damage.
● Use rapid acceleration only when visibility, weather, road conditions
and traffic permit.
WARNING
Do not allow the brakes to “rub” for a prolonged period of time, or brake
frequently or for long periods of time. Continuous braking heats up the
brakes. This could significantly reduce braking power, increase braking
distance or even result in the total failure of the brake system.
CAUTION
● Never make the brakes slip by pressing the pedal gently, if it is not really
necessary to brake. This will increase wear.
● Reduce speed or reduce the gear when faced with steep and long
slopes. This allows you to use the engine braking effect and to reduce the
strain on the brake system. Otherwise, the brakes may overheat and fail.
Only use the brakes to reduce speed or to stop. 

Driver assistance systems
Driver assistance systems
Parking sensor system*
Introduction
The parking sensor system assists the driver when parking. If the rear of the
vehicle is approaching an obstacle, an intermittent audible warning is emit-
ted. The shorter the distance, the shorter the intervals between tones. If the
vehicle is too close to the obstacle, the audible warning becomes constant.
If you continue to approach an obstacle when the sound is continuous, this
means the system can no longer measure the distance.
Sensors situated on the rear bumper transmit and receive ultrasound. Using
the ultrasound signal (transmission, reflection from the obstacles and re-
ception), this system continuously calculates the distance between the
bumper and the obstacle.
Additional information and warnings:
● Exterior detail ⇒ page 6
● Accessories, parts replacement, repairs and modifications ⇒ page 222
WARNING
The parking distance warning system cannot replace the driver's assess-
ment of the situation.
● The sensors have blind spots in which obstacles and people are not
registered.
● Always observe the area around the vehicle, as the sensors do not al-
ways detect small children, animals or objects.
WARNING (Continued)
● The surface of certain objects and some clothing do not reflect the ul-
trasound signals from the parking distance system. The system cannot
detect or incorrectly detects these objects and people wearing these
types of clothes.
● External sound sources can affect the parking distance aid signals. In
this case, under certain circumstances, people and objects will not be de-
tected.
CAUTION
● The sensors may not always be able to detect objects such as trailer
draw bars, thin rails, fences, posts, trees and open luggage compartments,
etc. This could result in damage to your car.
● Although the parking sensor system detects and warns of the presence
of an obstacle, the obstacle could disappear from the angle of measure-
ment of the sensors if it is too high or low and the system would no longer
indicate it. Therefore, it will not warn you of these objects. Ignoring the
warnings of the parking sensor system could cause considerable damage to
the vehicle.
● The bumper sensors may become damaged or misaligned, for example,
when parking.
● To ensure that the system works properly, the bumper sensors must be
kept clean, free of ice and snow and uncovered.
● When cleaning the sensors with high-pressure or steam cleaning equip-
ment, spray the sensors briefly at a distance of no less than 10 cm.
● Different sources of noise can produce errors in the parking distance
warning system, e.g. parking distance warning systems from other vehicles,
inductive loops or construction works machines.
● Retrofitting of components to the vehicle, such as a bicycle carrier, may
interfere with the function of the parking distance warning system. 
