The brake and stabilization systems are automatically activated each time the
ignition is switched on, unless otherwise indicated.WARNINGThe general information relating to the use of assistance systems must be
observed » page 105, in section Introduction .
Stability Control (ESC)
Read and observe
on page 106 first.
The ESC improves vehicle stability in dynamic driving situations, such as whenthe vehicle starts to skid.
The ESC monitors whether the desired direction of the current vehicle motion
is occurring. In case of any deviation (e.g. over-steer), the ESC automatically
brakes individual wheels to maintain the desired direction.
During an intervention of the system, the warning light flashes in the instru-
ment cluster.
Anti-lock braking system (ABS)
Read and observe
on page 106 first.
ABS prevents the wheels locking when braking. Thus helping the driver to
maintain control of the vehicle.
The intervention of the ABS is noticeable from the pulsating movements of
the brake pedal which is accompanied by noises.
When the ABS system is active, do not brake periodically or reduce the pres-
sure on the brake pedal.
Traction control (TCS)Fig. 114
System button: Activating/deac-
tivating TCS
Read and observe on page 106 first.
TCS prevents the spinning of the wheels of the driven axle. TCS reduces the drive power transmitted to the wheels in the case of slipping wheels. Thus, for
example, driving on road surfaces with low grip is made easier.
During a TCS intervention, the indicator light flashes in the instrument clus-
ter.
Activating/deactivating TCS
The activation or deactivation of TCS can be done, depending on equipment, in
one of the following ways. ▶ Infotainment » Owner´s Manual Infotainment , chapter CAR - vehicle set-
tings .
▶ By briefly pressing the symbol key
» Fig. 114 .
The warning light illuminates in the instrument cluster when the TCS is deacti-
vated .
The TCS should normally always be enabled. The system should be deactivated
only in the following situations, for example. ▶ When driving with snow chains.
▶ When driving in deep snow or on a very loose surface.
▶ When “rocking a car free” when it has become stuck.

the vicinity of the vehicle.
WARNING■ The general information relating to the use of assistance systems must
be observed » page 105, in section Introduction .■
Moving persons or objects may not be recognized by the system sensors.
■
Under certain circumstances, surfaces of certain objects and types of
clothing cannot reflect the system signals. For this reason, such people or
objects may not be recognised by the system sensors.
■
External noise sources may affect the signals of the system sensors. Un-
der adverse conditions, this may cause objects or people not to be recog-
nised by the system.
■
Before reversing, you should make sure that there are no small obstacles,
such as rocks, thin posts, trailer draw-bars etc. in front or behind your vehi-
cle. Such obstacles may not be recognised by the system sensors.
CAUTION
■ Keep the system sensors » Fig. 115 on page 108 clean, snow-and ice-free
and do not cover with any objects of any kind, otherwise the system function-
ing may be impaired.■
Under adverse weather conditions (heavy rain, water vapour, very low or
high temperatures, etc.), the system function may be limited - “incorrect recog-
nition of obstacle”.

cally connected trailer, the system becomes unavailable.Radar sensorFig. 123
Mounting location of the radar
sensor
Read and observe and on page 112 first.
The radar sensor » Fig. 123(hereinafter referred to as the sensor) may detect
objects by radiating and receiving electromagnetic waves.
The sensor function may be impaired in the events of one of the following. ▶ The sensor is soiled by mud, snow and the like.
▶ The area in front and around the sensor is obscured by labels, auxiliary lights
and similar.
▶ When visibility is poor, (e.g. fog, heavy rain, thick snowfall).
If the sensor is dirty or covered, the corresponding message appears on the
display of the instrument cluster » page 114, Information messages .
WARNING■
If you suspect that the sensor is damaged, deactivate the system. Have
the sensor checked by a specialist garage.■
The sensor can become misaligned by collisions or by damage to the front
of the vehicle, the wheel arch or the underside of the vehicle. This can lead
to impaired function of the sensor - risk of accidents! Have the sensor
checked by a specialist garage.
■
The area in front and around the sensor should not be obscured by labels,
auxiliary lights and similar. This can lead to impaired function of the sensor
- risk of accidents!

OperationRead and observe
and on page 112 first.
The system support is provided in the following manner.▶ Alerts you about a dangerous proximity to the vehicle ahead.
▶ Warns you of an impending collision.
▶ Prepares the brakes for emergency braking prior to a detected danger.
▶ Assists with a brake action triggered by the driver.
▶ If the driver fails to respond to a detected danger, an automatic braking ac-
tion is performed.
The system can work only if the following basic conditions are met. The system is activated.
The TCS is activated » page 106, Traction control (TCS) .
The vehicle is moving forwards at a speed of more than approx. 5 km/h.
Note
The system can be impaired or may not be available, for example when driving
in “sharp ”curves or with an ESC engagement » page 106.
Distance warning (dangerous distance)
Fig. 124
Symbols in the instrument cluster: Note (dangerous
proximity)
Read and observe and on page 112 first.
The display of the distance warning is for vehicles with MAXI DOT display.
If a safe interval to the vehicle ahead falls below a minimum the display of the
instrument cluster shows the symbol
» Fig. 124 .
Immediately increase the proximity if the current traffic situation allows you to do so!
The proximity at which the warning is displayed depends on the current speed.
The warning may occur when driving between about 60 km/h and 210 km/h.
Warning and automatic braking
Fig. 125
Symbols in the instrument cluster: Warning or emer-
gency braking at low speed
Read and observe and on page 112 first.
Emergency braking at low speed
In a driving speed range of about 5 km/h to about 30 km/h the automatic brak- ing action is not preceded by a warning. With an immediate impact hazard au-
tomatic braking is done with the breaking force increasing in stages.
With automatic braking the symbol appears » Fig. 125
in the display.
Advance warning
If the system detects a risk of collision, the symbol » Fig. 125
appears in the
display and you will hear an acoustic signal.
At the same time, the braking system is prepared for possible emergency brak- ing.
The pre-warning display can occur in the following situations. ▶ If there is a risk of collision with a moving obstacle in a driving speed range of
about 30 km/h to about 210 km/h.
▶ There is a risk of a collision with a stationary moving obstacle in a vehicle
speed range of approximately 30 km/h to about 85 km/h.
With a warning the brake pedal must be pressed or the moving obstacle is to
be avoided!
Acute alert
If the driver does not react to the advance warning, the system briefly applies
the brake automatically via an active brake intervention to draw attention to
the potential danger of a collision again.
113Assist systems

Automatic Braking
If the driver fails to respond to the acute warning, the system starts to apply
the brakes automatically with increasing stopping power in several stages.
Brake assist
If the driver brakes inadequate with an impending collision, the system auto-
matically increases braking force.
The braking assistance only occurs as long as the brake pedal is being firmly
pressed down.
Note
■ If an automatic brake intervention is triggered by the system, the pressure in
the brake system increases and the brake pedal cannot be operated with the
normal pedal stroke.■
The automatic braking interventions can be cancelled by pressing the accel-
erator pedal or by steering intervention.
