The sensor is part of the ACC» page 110 and Front Assist » page 114systems.
The sensor function may be impaired in the events of one of the following. ▶ The sensor cover is soiled (e.g. with mud, snow etc.).
▶ The area in front of and around the sensor cover is obscured (e.g. by labels,
auxiliary headlights etc.).
▶ When visibility is poor, (e.g. fog, heavy rain, thick snowfall).
If the sensor is covered or dirty, the corresponding message appears in the in-
strument cluster display for the ACC system » page 114, Malfunctions or Front
Assist system » page 116, Malfunctions .WARNING■
If you suspect that the sensor is damaged, deactivate the ACC system and
Front Assist system » page 111, » page 116 . Have the sensor checked by a
specialist garage.■
A collision or damage in the front or lower area of the vehicle could affect
the sensor function - there is risk of accident! Have the sensor checked by
a specialist garage.
■
Do not cover the area in front of and around the sensor cover. This can
lead to impaired function of the sensor - risk of accidents!
CAUTION
Remove the snow with a brush and the ice with a solvent-free de-icer.

Electronic differential lock (EDL and XDS)

The brake and stabilization systems are automatically activated each time the
ignition is switched on, unless otherwise indicated.
The error display is in Chapter » page 28, Warning lights .WARNINGThe general information relating to the use of assistance systems must be
observed » page 100, in section Introduction .
Stability Control (ESC)
Read and observe
on page 101 first.
The ESC improves vehicle stability when driving at the limit (e.g. if the vehiclestarts to skid) by braking individual wheels to maintain the desired direction.
If there is a TCS intervention, the indicator light flashes in the instrument
cluster.
Anti-lock braking system (ABS)
Read and observe
on page 101 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.
Engine drag torque control (MSR)
Read and observe
on page 101 first.
MSR counteracts the tendency of the drive wheels to lock during downshifts
or sudden deceleration (e.g. on icy or an otherwise slippery road surface).
If the drive wheels should lock, then the engine speed is automatically in-
creased. This reduces the braking effect of the engine and the wheels can ro-
tate freely again.
101Assist systems
Traction control (TCS)Fig. 126
Key for the TCS system
Read and observe on page 101 first.
TCS prevents the spinning of the wheels of the driven axle. TCS reduces thedrive 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.
The deactivation/activation of TCS can be carried out, depending on equip-
ment, in one of the following ways. ▶ Infotainment » Owner's Manual Infotainment .
▶ By pressing the
» Fig. 126 button.
During deactivation the warning light lights up in the instrument cluster
and
an appropriate message is displayed in the instrument cluster.
During activation extinguished the warning light
is and an appropriate mes-
sage is displayed in the instrument cluster.
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 101 first.
EDL prevents the turning of the respective wheel of the driven axle. EDL
brakes a spinning wheel if required and transfers the drive power force to the
other drive wheel. Driving becomes easier on road surfaces with different trac-
tion under each wheel of the driven axle.
EDL switches off automatically to avoid excessive heat generation on the
brake of the wheel being braked. Once the brakes have cooled down, there is
an automatic re-activation of EDL.
XDS is an extension to the electronic differential lock (EDL). XDS does not re-
spond to the relieved inner curve wheel of the driven axle in the case of fast
cornering.
By applying braking force to the relieved wheel, spinning is prevented by the
XDS. This has a positive effect on the driving stability and steerability of the
vehicle.
Brake Assist (HBA)
Read and observe
on page 101 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 Start Assist (HHC)
Read and observe
on page 101 first.
When moving off on a gradient, HHC allows you to move your foot from thebrake pedal to the accelerator pedal without the vehicle rolling downhill.
The vehicle is braked by the system for about 2 seconds after releasing the
brake pedal.
The HHC is active on gradients upwards of 5 % if the driver door is closed. HHC
is always only active on slopes pulling away forwards or in reverse.
102Driving
Multi collision brake (MCB)Read and observe
on page 101 first.
MCB helps to decrease speed after a collision by means of automatic braking
interventions and to stabilise 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.
There was a front, side and rear-end collision of a certain severity.
The impact speed was greater 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.

The parking aid (hereinafter referred to as "system") draws attention to obsta-
cles in the vicinity of the vehicle via acoustic signals or on the Infotainment
display when manoeuvring.
WARNING■ The general information relating to the use of assistance systems must
be observed » page 100, in section Introduction .■
Moving persons or objects may not be recognised by the system sensors.
■
Under certain circumstances, surfaces of certain objects and types of
clothing cannot reflect the system signals. There is a danger that such ob-
jects or people may not be recognised by the system sensors.
WARNING (Continued)■ External noise sources may affect the signals of the system sensors.
There is a danger that obstacles may not be recognised by the system sen-
sors.■
Before reversing, you should satisfy yourself that there are no small ob-
stacle, such as a rock, thin post etc., in front or behind your vehicle. Such
obstacles may not be recognised by the system sensors.
CAUTION
■ Keep the system sensors » Fig. 127 on page 103 clean, snow-and ice-free
and do not cover with any objects of any kind, otherwise the system function-
ing may be impaired.■
In adverse weather conditions (heavy rain, water vapour, very low or high
temperatures, etc.), the functioning of the system may be impaired - “incorrect
recognition of obstacles”.
■
Accessories additionally installed on the vehicle rear, such as bicycle carriers,
can impair the system function.

warning light lights up in the instrument cluster.
Exceeding the speed limit during the regulation
If, during the setting, it is necessary to exceed the speed limit (e.g. to over-
take), the accelerator pedal must be pressed fully.
When exceeding the speed limit (e.g. driving down a hill), an acoustic signal
sounds and the warning light flashes in the instrument cluster.
The regulation is resumed once the speed has fallen below the set limit.
