Seat belts
Seat belts
Brief introduction Before driving: remember your seat belt!
Wearing a seat belt properly can save your life!
In this chapter you will learn the importance of wearing seat belts,
how they work and how to properly fasten, adjust and wear them.
– Read and consider all the information as well as the warnings in
this chapter.
WARNING
● If seat belts are worn incorrectly or not at all, the risk of severe inju-
ries increases.
● Properly worn seat belts can reduce severe injuries in case of sudden
braking manoeuvres or accidents. For safety reasons, you and your pas-
sengers must always wear the seat belts properly while the vehicle is
moving.
● Pregnant women or people with physical disabilities must also use
seat belts. Like all other passengers, these people can also sustain se-
vere injuries if they are not wearing their seat belts properly.

Number of seats
Your vehicle has five seats, two in the front and three in the rear. Each seat
is equipped with a three-point seat belt. In some versions, your vehicle is approved
only for four seats. Two front
seats and two rear seats.
WARNING
● More people than available seats must never be transported in your
vehicle.
● Every passenger in the vehicle must properly fasten and wear the
seat belt belonging to his or her seat. Children must be protected with an
appropriate child restraint system.

Seat belt warning lamp* 
The warning lamp acts as a reminder to the driver to fasten
the seat belt.
Before starting the vehicle:
– Fasten your seat belt securely.
– 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. 

Seat belts
Why wear seat belts? Physical principles of frontal collisions
In the event of a frontal collision, a large amount of kinetic
energy must be absorbed.
Fig. 7 Vehicle about to
hit a wall: the occupants
are not wearing seat
belts
Fig. 8 The vehicle hits
the wall: the occupants
are not wearing seat
belts
It is easy to explain how the laws of physics work in the case of a head-on
collision: When a vehicle starts moving ⇒ fig. 7, a certain amount of energy
known as kinetic energy is produced in the vehicle and its occupants.
The amount of kinetic energy depends on the speed of the vehicle and the
weight of the vehicle and its passengers. The higher the speed and the
greater the weight, the more energy there is to be released in an accident.
The most significant factor, however, is the speed of the vehicle. If the
speed doubles from 25 km/h to 50 km/h, for example, the kinetic energy is
multiplied by four.
Because the passengers in our example are not restrained by seat belts, in
the case of a head-on collision all of their kinetic energy has to be absorbed
at the point of impact ⇒ fig. 8.
Even at speeds of 30 km/h to 50 km/h, the forces acting on bodies in a col-
lision can easily exceed one tonne (1000 kg). At greater speed these forces
are even higher.
Passengers not wearing seat belts are not “attached” to the vehicle. In a
head-on collision, they will move forward at the same speed their vehicle 

Coolant level* / temperature 
The warning lamp lights up if the coolant temperature is too
high or if the coolant level is too low.
There is a fault if:
● The warning symbol does not go out again after a few seconds.
● The warning lamp lights up or flashes while the vehicle is moving, and
three acoustic warning signals ⇒ 
are emitted.
This means that either the coolant level is too low or the coolant tempera-
ture is too high.
Coolant temperature too high
The instrument panel displays the following message 1)
: CHECK COOLANT IN-
STRUCTION MANUAL. ⇒  page 226.
First look at the coolant temperature gauge. The coolant temperature is too
high if the needle is over the warning area on the dial. Stop the vehicle,
switch the engine off and wait for it to cool down. Check the coolant level.
If the coolant level is correct, the overheating may be caused by a malfunc-

Soot accumulation in the diesel engine particulate filter*

If the warning lamp  lights up you should help the filter clean itself by
driving in the appropriate manner.
To do this, drive about 15 minutes in fourth or fifth gear (automatic gear-
box: S gear range) at a speed of 60 km/h, with the engine running at ap-
proximately 2000 rpm. In this way, the pollen build up in the filter is burned.
When cleaning is successful, the indicator turns off.
If the warning lamp  does not turn off, or the three lamps turn on (partic-
ulate filter  , emission control system fault  and glow plugs ), take
the vehicle to a specialised workshop to repair the fault.
WARNING
● Always drive according to the road weather conditions, the terrain
and traffic. Driving recommendations should never lead to illegal ma-
noeuvres in surrounding traffic.
● The diesel engine particulate filter may reach extremely high temper-
atures; it should not enter into contact with flammable materials under-
neath the vehicle. Otherwise there is a risk of fire.

charging the battery. You should immediately drive to the nearest special-
ised workshop.
You should avoid using electrical equipment that is not absolutely necessa-
ry because this will drain the battery. 
Worn brake pads 
If the  symbol lights up, have the front brake pads (and, for safety rea-
sons, the rear pads as well) inspected by a specialised workshop. Tyre pressure 
The tyre pressure control system controls the tyre speed and
the frequency spectrum of each tyre.

The tyre warning lamp 1)
compares wheel revolutions and with this informa-
tion, the diameter of each wheel using the ESC (ESP) sensors. If the diame-
ter of a wheel changes, the tyre warning lamp  lights up. The wheel diam-
eter changes when:
● Tyre pressure is insufficient.
● The tyre structure is damaged.
● The vehicle is unbalanced because of a load.
● The wheels of one axle are under more pressure (for example, driving
with a trailer or on extreme slopes).
● The vehicle is fitted with snow chains. 
