20Seat 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. 6 Vehicle about to
hit a wall: the occupants
are not wearing seat
belts
Fig. 7 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. 6, 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 (15 mph) to 50 km/h (30 mph), for example,
the kinetic energy is multiplied by four.
Because the vehicle occupants in our example are not restrained by seat
belts, all of the occupants' kinetic energy has to be absorbed at the point of
impact ⇒ Fig. 7.
Even at speeds of 30 km/h (20 mph) to 50 km/h (30 mph), the forces acting
on bodies in a collision can easily exceed one tonne (1000 kg). At greater
speed these forces are even higher.

22Seat belts
Seat belt protection
Passengers not wearing seat belts risk severe injuries in the
event of an accident.
Fig. 10 A driver wearing
the seat belt properly is
secured by the belt in
sharp braking
Properly worn seat belts hold the vehicle occupants in the correct sitting po-
sitions and substantially reduce the kinetic energy in the event of an acci-
dent. Seat belts also help to prevent uncontrolled movements that could
lead to severe injuries. In addition, properly worn seat belts reduce the dan-
ger of being thrown from the vehicle.
Vehicle occupants wearing their seat belts correctly benefit greatly from the
ability of the belts to absorb kinetic energy. The front part of your vehicle
and other passive safety features (such as the airbag system) are also de-
signed to absorb the kinetic energy released in a collision. Taken together,
all these features reduce the releasing kinetic energy and consequently, the
risk of injury.
Our examples describe frontal collisions. Of course, properly worn seat belts
substantially reduce the risk of injury in all other types of accidents. This is
why it is so important to fasten seat belts before every trip, even when "just
driving around the corner". Ensure that your passengers wear their seat belts as well. Accident statistics
have shown that wearing seat belts is an effective means of substantially
reducing the risk of injury and improving the chances of survival in a seri-
ous accident. Furthermore, properly worn seat belts improve the protection
provided by airbags in the event of an accident. For this reason, wearing a
seat belt is required by law in most countries.
Although your vehicle is equipped with airbags, the seat belts must be fas-
tened and worn. The front airbags, for example, are only triggered in some
frontal accidents. The front airbags will not be triggered during minor frontal
collisions, minor side collisions, rear collisions, overturns or accidents in
which the airbag trigger threshold value in the control unit is not exceeded.
Therefore, you should always wear your seat belt and ensure that all vehicle
occupants have fastened their seat belts properly before you drive off!
Safety instructions on using seat belts
If seat belts are used correctly, they can considerably reduce
the risk of injury in an accident.
– Always wear the seat belt as described in this section.
– Ensure that the seat belts can be fastened at all times and are
not damaged.

30Airbag system
The danger of fitting a child seat on the front passenger
seat
Rear-facing child seats must never be used on the front pas-
senger seat when the front passenger airbag is enabled.
The front passenger front airbag is a serious risk for a child if it is activated.
The front passenger seat is life threatening to a child if he/she is transpor-
ted in a rear-facing child seat. Children up to 12 years old should always
travel on the rear seat.
If a rear-facing child seat is secured to the front passenger seat, an inflating
airbag can strike it with such force that it can cause critical or fatal injuries.
Therefore we strongly recommend you to transport children on the rear
seats. That is the safest place for children in the vehicle. Alternatively, the
front passenger airbag can be disabled with a key-operated switch
⇒ page 40. When transporting children, use a child seat appropriate to
the age and size of each child.
For those vehicles that do not include a key lock switch to deactivate the air-
bag, the vehicle must be taken to a Technical Service.
WARNING
● If a child seat is secured to the front passenger seat, the risk to the
child of sustaining critical or fatal injuries in the event of an accident in-
creases.
● Never secure a rear-facing child seat to the front passenger seat if the
front passenger airbag is enabled. The child can suffer critical or fatal in-
juries if the front passenger airbag is triggered.
WARNING (Continued)
● An inflating front passenger airbag can strike the rear-facing child
seat and project it with great force against the door, the roof or the back-
rest.
● If, under special circumstances, it is necessary to transport a child in
a rear-facing child seat on the front passenger seat, it is absolutely es-
sential that you observe the following safety measures:
–Deactivate the front passenger airbag ⇒ page 40, Deactivating
airbags*.
– Child seats must be approved by the child seat manufacturer for
use on a front passenger seat with front or side airbag.
– Follow the installation instructions of the child seat manufacturer
and absolutely observe all warnings
– Before properly installing the child seat, push the front passenger
seat completely backwards so that the greatest possible distance to
the front passenger airbag is ensured.
– Ensure that no objects prevent the front passenger seat from being
pushed completely back.
– The backrest of the front passenger seat must be in an upright po-
sition.
Control lamp for airbag and seat belt tensioner
This control lamp monitors the airbag and seat belt tension-
er system.
The control lamp monitors all airbags and seat belt tensioners in the vehi-
cle, including control units and wiring connections.

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.
Engine oil pressure
If this warning lamp is red it indicates that the engine oil
pressure is too low.
If this warning symbol starts to flash, and is accompanied by three audible
warnings, switch off the engine and check the oil level. If necessary, add
more oil ⇒ page 199.
If the symbol flashes although the oil level is correct, do not drive on. Do
not even run the engine at idle speed! Obtain technical assistance.
Checking the oil level
If the warning lamp is yellow the engine oil level should be checked as
soon as possible. Top up the oil ⇒ page 199 at the next opportunity.
Oil level sensor faulty*
If the yellow warning lamp flashes, take the vehicle to a specialised
workshop to have the oil level sensor checked. Until then it is advisable to
check the oil level every time you refuel. Bulb defect*
The indicator lights up when a bulb is not functioning.
The warning lamp lights up when there is a fault on the turn signals,
headlights, side lights and fog lights.
Washer fluid
This warning lamp lights up to indicate that the windscreen
washer level is too low. This serves as a reminder to fill up the reservoir at the earliest opportunity
⇒ page 202.
Rear fog light*
This warning lamp lights up when the rear fog light is switched on . For
further information see ⇒ page 97.
Anti-lock brake system (ABS)*
A control lamp monitors the ABS.
The control lamp should light up for a few seconds when the ignition is
switched on. It goes out again after the system has run through an automat-
ic test sequence.
Safety FirstOperating InstructionsPractical TipsTechnical Specifications

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.

71
Cockpit
Electronic Stability Control (ESC)* /
There are two warning lamps for the Electronic stability con-
trol. The lamp provides information concerning the func-
tion and the provides information on the disconnection
status
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.
This programme includes the ABS, EDL and ASR. It also includes emergency
braking assistance (BAS).
The warning lamp has the following functions:
● It flashes whilst driving when the ASR/ESC is activated.
● It will light up continuously if there is a fault in the ESC.
● As the ESC operates in conjunction with the ABS, it will also light up if a
fault should occur in the ABS.
If the ESC control lamp lights up and stays on after the engine is started,
this may mean that the control system has temporarily switched off the ESC.
In this case the ESC can be reactivated by switching the ignition off and
then on again. If the control lamp goes out, this means the system is fully
functional.
The lamp provides information about the disconnection status of the
system:
● It stays lit when the ASR is disconnected when pressing the switch.Brake system* This warning lamp lights up if the brake fluid level is too low
or if there is a fault in the system.
This warning lamp
lights up if
● the brake fluid level is too low ⇒ page 206.
● there is a fault in the brake system.
This warning lamp can light up together with the ABS system warning lamp.
WARNING
● If the brake warning lamp does not go out, or if it lights up when driv-
ing, the brake fluid level ⇒ page 206, Brake fluid in the reservoir is too
low. Risk of accident. Stop the vehicle and do not drive on. Obtain techni-
cal assistance.
● If the brake warning lamp lights up together with the ABS warning
lamp , the control function of the ABS could be out of action. 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 tech-
nical assistance.
Cruise speed (Cruise control)*
The warning lamp comes on when the cruise control system
is switched on.
The warning lamp lights up when the cruise control system is switched
on. For further information on the cruise control system, see ⇒ page 158.
