of the other vehicle system functions may be limited.
Antilock Braking System (ABS)
First read and observe the introductory information and safety warn-
ings
on page 137.
ABS prevents the wheels locking when braking. Thus helping the driver to main-
tain 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 pressure
on the brake pedal.
Traction Control System (TCS)
Fig. 128
TCS button
First read and observe the introductory information and safety warn- ings on page 137.
If the wheels are slipping, the TCS system adapts the engine speed to the condi-
tions of the road surface. The TCS makes it much easier to start off, accelerate
and climb steep hills even if the conditions of the road surface are unfavourable.
The TCS function is automatically activated each time the ignition is switched on.
If your vehicle is fitted with the ESC system, the ASR is integrated into the ESC
system » page 137 .
138Driving
During an intervention of the system, the TCS warning light flashes in the in-
strument 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 it is necessary to “rock” a car free when it has become stuck.
The TCS can be deactivated in the Infotainment or with the symbol button
» Fig. 128 » Infotainment manual , chapter Vehicle settings (CAR button) .
The warning light lights up in the instrument cluster when the TCR is deactiva-
ted.
Ensure the TCS is activated again afterwards.
Electronic Differential Lock (EDL and XDS)
First read and observe the introductory information and safety warn-
ings
on page 137.
EDL
If one of the wheels starts to spin, the EDL system brakes the spinning wheel and
transfers the driving force to the other wheels. This ensures the stability of the
vehicle and a quick journey.
The EDL switches itself off automatically, in order to avoid excessive heat genera-
tion in the disc 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. The EDL
switches on again automatically as soon as the brake has cooled down.
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 during
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 vehicle can continue to follow the desired track.
Driver Steering Recommendation (DSR)
First read and observe the introductory information and safety warn-ings
on page 137.
The DSR indicates to the driver in critical situations a steering recommendation in
order to stabilise the vehicle. The DSR is activated, for example, on the right and
left vehicle side when braking sharply on different road surfaces.
Hydraulic Brake Assist (HBA)
First read and observe the introductory information and safety warn-ings
on page 137.
HBA increases the braking effect and helps to shorten the braking distance.
The HBA is activated by the very quick operation of the brake pedal. To achieve
the shortest possible braking distance, the brake pedal must be applied firmly un-
til the vehicle has come to a complete standstill.
The HBA is automatically switched off when the brake pedal is released.The ABS is activated faster and more effectively with the intervention of the HBA.
Hill Hold Control (HHC)
First read and observe the introductory information and safety warn-ings
on page 137.
HHC allows you, when driving on slopes, to move your foot from the brake pedal
to the accelerator pedal without having to use the handbrake.
The system holds the brake pressure produced by the activation of the brakepedal for approx. 2 seconds after the brake pedal is released.
The brake pressure drops gradually the more you operate the accelerator pedal. Ifthe vehicle does not start off within 2 seconds, it starts to roll back.
The HHC is active from a 5% slope if the driver's door is closed. HHC is always ac-tive on slopes when in forward or reverse start off. When driving downhill, it is in- active.

The Cruise Control System (CCS) maintains a set speed, more than 25 km/h, with-
out you having to actuate the accelerator pedal.
This is only possible within the range which is permitted by the power output and
braking power of the engine.
The warning light
illuminates in the instrument cluster when the cruise control
system is switched on.
WARNING■ For safety reasons, the cruise control system must not be used in dense
traffic or on unfavourable road surfaces (such as icy roads, slippery roads,
loose gravel) – risk of accident!■
The saved speed may only be resumed if it is not too high for the current
traffic conditions.
■
Always deactivate the cruise control system after use to prevent uninten-
tional switching on of the system.
CAUTION
■ The cruise control system is not able to maintain a constant speed when driving
in areas with very steep gradients. The weight of the vehicle increases the speed
at which it travels. In such cases, a lower gear should be engaged or the foot-
brake applied.■
It is not possible to switch on the cruise control system if the first gear or re-
verse gear is engaged (Vehicles fitted with a manual transmission)
■
The cruise control system cannot be activated when the selector lever is in po-
sitions P, N or R (vehicles with automatic transmission).
146Driving
Briefly push the rocker button B into the RES/+ position in order to resume the
stored speed after the clutch or brake pedal is released.

Adaptive cruise control (From here on referred to only as ACC) can maintain the
set speed or the proximity to the vehicle ahead consistently, without the need to
operate the gas or brake pedals.
The state in which the ACC maintains the speed or the proximity is described as
control from here on.
WARNING■
The ACC only works as an aid - it does not absolve the driver of the respon-
sibility to maintain full control over the vehicle's steering.■
Always adapt your speed and safety proximity to the vehicle ahead to the
current visibility, weather, road and traffic conditions.
■
The driver must always be ready to take over steering of the vehicle himself
(accelerate or brake).
Note
■ The ACC is designed primarily for use on motorways.■Some ACC notifications in the display of the instrument cluster may be hidden
by notifications for other functions. An ACC notification automatically appears for
a brief moment when there is a change in status of the ACC.
Instructions and Information
First read and observe the introductory information and safety warn-ings
on page 148.
WARNING■ The ACC does not react when approaching a stationary obstacle, such as
traffic jams, vehicle breakdowns or vehicles waiting at a traffic light.■
The ACC does not respond to crossing or oncoming objects. 148Driving
WARNING (Continued)■If the ACC does not decelerate fast enough, immediately apply the vehicle's
footbrake.■
Control may only be resumed if the stored speed is not too high for the cur-
rent traffic conditions.
WARNINGFor safety reasons, do not use the ACC under the following conditions.■When driving in turning lanes, motorway exits or construction sites, to avoid
an unwanted acceleration to the stored speed.■
When visibility is poor, (e.g. fog, heavy rain, thick snowfall).
■
When road conditions are poor (e.g. ice, slippery road, gravel, dirt road).
■
When driving around “sharp” bends.
■
When riding on a steep gradient / high slope.
CAUTION
■ It is not possible to switch on the control on vehicles fitted with a manual
transmission if the first gear or reverse gear is engaged.■
It is not possible to switch on the control on vehicles fitted with an automatic
transmission , if the selector lever is in the position P, N or R .
■
The control may automatically switch off when some brake assist systems (e.g.
ESC) intervene, when the maximum permissible engine speed is exceeded, etc.
Note
■ The speed can only be set and stored when ACC is activated. The stored speed
may differ from the actual speed if a proximity control procedure is in progress at the time.■
Vehicles with an automatic transmission can decelerate to a standstill and start
again using the ACC.
■
The ACC reduces the speed by automatically releasing the accelerator or by
means of a braking procedure as appropriate. If the brakes are used for an auto-
matic speed reduction at any moments, then the brake light illuminates.
■
In case of failure of more than one brake light on the vehicle or on the electri-
cally connected trailer, the ACC becomes unavailable.
Radar sensorFig. 135
Mounting location of the radar
sensor
First read and observe the introductory information and safety warn-
ings on page 148.
The radar sensor » Fig. 135 (From here on referred to as sensor) is used to assess
the traffic situation in front of the vehicle.
The sensor can distinguish objects by radiating and receiving electromagneticwaves.
The sensor function may be impaired in the events of one of the following.
› The sensor is covered by mud, snow or debris, for example.
› The sensor or its immediate surroundings are covered by other objects, for ex-
ample, a sticker is attached.
› When visibility is poor, (e.g. fog, heavy rain, thick snowfall).
If the sensor is dirty or does not have “visibility” for any other reason, the follow- ing message appears in the instrument cluster display.
ACC: no sensor view!
Stop the car, switch off the engine and clean the sensor or eliminate the obstacle
causing the lack of“visibility”. Should the ACC still be unavailable after the engine is restarted,
» Fig. 138 on page 151 push the lever into position. Seek help
from a specialist garage.
149Assist systems
WARNING■If you suspect that the sensor is damaged, deactivate the ACC. 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 an
impairment of the ACC function - risk of accidents! If this is the case, have the
sensor checked by a specialist garage.
■
Any improperly carried out work to the front of the vehicle may cause the
sensor to become misaligned. We therefore recommend only having these
modifications and technical alterations carried out by a specialist garage.
Please also observed the instructions in » page 200, Service work, adjust-
ments and technical alterations .
■
The area in front of and around the sensor must not be covered with stick-
ers, additional lights or similar items. This can lead to impaired function of the sensor - risk of accidents!
CAUTION
The sensor may not be able to distinguish all objects correctly under certain cir-cumstances. We therefore recommend that you avoid using the ACC in the follow-
ing cases.■
When driving through places where metal objects (such as metal buildings, rail-
road tracks, etc.) can be found.
■
When driving through very divided and enclosed spaces (such as large-capacity
garages, car ferries, tunnels and the like.).
CAUTION
Remove the snow with a brush and the ice with a solvent-free de-icer.

The ACC can consistently maintain the set speed of 30-160 km/h, as well as the
proximity to the vehicle ahead ranging from a very small to a very large time inter-
val.
The ACC adjusts the set speed with respect to the detected vehicle ahead, thus
maintaining the selected proximity.
If the ACC does not decelerate fast enough with respect to the vehicle ahead, the symbol
and the following message both appear in the instrument cluster dis-
play.
Apply the brake!
Take over the steering and apply the brake! The ACC can detect a vehicle that is up to approx.120m ahead using the radar
sensor .
Automatic stop-start
First read and observe the introductory information and safety warn-
ings
on page 148.
Vehicles with an automatic transmission can decelerate to a standstill and start
moving again using the ACC.
Decelerate to a standstill
If a vehicle ahead decelerates to a standstill, the ACC will also decelerate your ve-
hicle to a standstill.
Starting to drive again after a holding period As soon as the vehicle ahead starts moving again after a holding period, your ve-hicle will also move and the speed will continue to be regulated. Control is auto-
matically disconnected in case of longer holding periods.
Take over the steering and apply the brake.
