This chapter deals with the functions of the braking and stabilisation systems,
with the error indicator referred to in chapter » page 33, Warning lights .
The braking and stabilisation systems are automatically activated each time the ignition is switched on.
WARNING■ A lack of fuel can cause irregular engine running or cause the engine to
shut down. The brake assist systems would then fail to function – risk of
accident!■
The increased safety provided by the brake assist systems must not
tempt you to take safety risks – risk of accident!
■
Adjust the speed and driving style to the current visibility, weather, road
and traffic conditions.
Electronic Stability Control (ESC)
Read and observe
on page 115 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. oversteer), 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 115 first.
ABS prevents the wheels locking when braking. Thereby, it helps 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 pump the brakes or lift off the brake
pedal.
Traction Control System (TCS)
Fig. 113
System button: Activating/deac-
tivating TCS
Read and observe on page 115 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. Thereby,
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.
› In Infotainment
» Operating instructions for Infotainment , chapter Vehicle
settings (CAR button) .
› By briefly pressing the symbol key
» Fig. 113 .
115Assist systems
Upon deactivation, in the instrument cluster the indicator light illuminates
and the display shows the following message.
Traction control (TCS) deactivated.
ASR OFF
Upon activation, in the instrument cluster the indicator turns
and the display
shows the following message.
Traction control (TCS) activated.
ASR ON
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.
Electronic Differential Lock (EDL and XDS)
Read and observe
on page 115 first.
EDL
EDL prevents the turning of the respective wheel of the driven axle. EDL
brakes the spinning wheel, if necessary, and transmits the driving force to the
other driving wheel. Driving becomes easier on road surfaces with different
traction under each wheel of the driven axle.
EDL switches off automatically to avoid excessive heat generation on the
brake of the wheel being braked. The vehicle can continue to be driven and
has the same characteristics as a vehicle not fitted with EDL. Once the brakes
have cooled down, there is an automatic re-activation of EDL.
XDS
XDL is an extension to the electronic differential lock. XDL does not respond to
traction, but to the load relief of the inner front wheel of the driving axle dur-
ing fast cornering.
The automatic brake intervention on the brake of the wheel with reduced load
prevents the wheel from spinning. Thus, the traction is improved and the vehi-
cle can continue to follow the desired track.
Hydraulic Brake Assist (HBA)
Read and observe
on page 115 first.
HBA increases the braking effect and helps to shorten the braking distance.The HBA is activated by very rapid depression of the brake pedal. To achieve
the shortest possible braking distance, the brake pedal must be applied firmly
until the vehicle has come to a complete standstill.
HBA is automatically switched off when the brake pedal is released.
Hill Hold Control (HHC)
Read and observe
on page 115 first.
HHC allows you to move your foot from the brake pedal to the accelerator ped-al without having to use the handbrake when pulling away on a gradient.
The system holds the brake pressure produced by the activation of the brake
pedal for approx. 2 seconds after the brake pedal is released.
The brake pressure drops gradually the more you operate the accelerator ped-
al. If the vehicle does not start off within 2 seconds, it starts to roll back.
HHC is active on slopes of >5 % when the driver door is closed. HHC is always only active on slopes pulling away forwards or in reverse.
Multi-collision brake (MCB)
Read and observe
on page 115 first.
The MCB helps to decrease speed after a collision through automatic brakinginterventions and to stabilize the vehicle. This reduces the risk of a subse-
quent crash due to uncontrolled vehicle movement.
The automatic brake interventions can take place only if the following condi-
tions are met.
A head-on or side collision occurred.
The impact speed was higher than approx. 10 km/h.
The brakes, the ESL and other required electrical systems remain function-
al after impact.
The accelerator pedal is not actuated.
