tomatic brake assist does not exempt the driver from his/her responsibility for
the accelerator, brake and clutch.
Automatic braking for preventing cancellations caused by excessive speeds
To prevent the speed from exceeding 7 km/h and to subsequently prevent can-
cellation of the parking procedure, automatic brake support is initiated. The park-
ing procedure can be resumed after automatic braking.
Automatic braking takes place only once per parking procedure.
Automatic braking for damage limitation
The system detects an imminent collision based on the driving speed and the dis-
tance from the obstacle, automatic brake support is initiated.
The system function is ended after this automatic brake assist for damage limita- tion.WARNING■ Automatic brake assist only works as an element of the assist function. The
driver must always be ready to brake the vehicle him/herself.■
Automatic brake assist is ended after around 1.5 seconds. Depress the brak-
ing pedal so that the vehicle does not start moving by itself.

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

Control deactivated (vehicle detected).
Control activated (no vehicle detected).

Control activated (vehicle detected).
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.

151Assist systems
Narrow vehicles or vehicles travelling side by side
Narrow vehicles or vehicles travelling side by side are not detected by the radar
sensor until they are within the sensor's range » Fig. 139 - . This is especially
true for narrow vehicles, such as motorcycles.
If necessary, slow down the car by applying the brake.
Other vehicles changing lanes
Vehicles that change onto the lane with a small proximity » Fig. 140 - do not
have to be detected by the radar sensor in time. The result may be a delayed ACC
response.
If necessary, slow down the car by applying the brake.
Stationary vehicles
The ACC does not detect stationary objects! When a vehicle detected by the ACC turns or sheers off and there is a stationary vehicle in front of this vehi-cle, » Fig. 140 -
the ACC does not respond to the stationary vehicle.
In such cases, take over the steering and apply the brake.
When overtaking
When your vehicle is being controlled (the speed is lower than that which is stor-
ed) and the indicator is activated, the ACC interprets that the driver intends to
overtake. The ACC automatically accelerates the vehicle, thereby reducing the
proximity to a vehicle ahead.
If the vehicle changes to the fast lane and no vehicle is detected ahead, the ACC
accelerates until the set speed is reached and then keeps it constant.
Acceleration can be cancelled at any time by touch on the brake pedal or pressing
the button
on the control lever » Fig. 138 on page 151 .
Vehicles with special load or special body parts
Other vehicles with a load or with body parts protruding from the sides, back or
top of the vehicle contour may not be detected by the ACC.
Control should therefore be disabled whenever you are driving behind or overtak-ing such a vehicle.
Towing a trailer
When towing a trailer, the ACC control will be less powerful. The manner of driv- ing should therefore be adapted to this limitation.
Information messages
First read and observe the introductory information and safety warn-
ings
on page 148.
If the symbol
appears in the instrument cluster display when ACC is enabled, it
means that the ACC is not working.
The messages and information are indicated in the instrument cluster display. ACC: no sensor view!
The sensor is dirty or has no “visibility”. Stop the car, switch off the engine and
clean the sensor or remove the obstacle causing the lack of “visibility” » Fig. 135
on page 149 . Should the ACC still be unavailable after the engine is restarted,
push the lever into position
» Fig. 138 on page 151 . Seek help from a specialist
garage.
ACC not available.
Stop the vehicle, switch off the engine and then start it again. If the ACC is still not available, push the lever into position

154Driving
The area monitoring system (From here on only referred to as Front Assist) warns
you of the danger of a collision with an obstacle in front of the vehicle and tries to
avoid a collision or mitigate its consequences by automatically applying the
brakes as appropriate.WARNING■ Front Assist only works as an aid, it does absolve the driver of the responsi-
bility to maintain full control over the vehicle's steering.■
Front Assist has physical and system related limitations. For this reason, the
driver may experience some undesired or delayed system responses in certain
situations. You should therefore always be alert and ready to intervene!
■
Always adapt your speed and safety proximity to the vehicle ahead to the
current visibility, weather, road and traffic conditions.
■
If Front Assist gives a warning, then, depending on the traffic situation, im-
mediately slow down the car by applying the brakes or avoid the obstacle.
■
The increased safety through the Front Assist system must not tempt you
to take greater risks than otherwise – risk of accident!
■
The driver must always be ready to take over steering of the vehicle himself
(brake or accelerate).
■
Front Assist does not respond to crossing or oncoming objects.
Instructions and Information
First read and observe the introductory information and safety warn-ings
on page 154.
Front Assist may become impaired in the following situations, for example.
› When visibility is poor, (e.g. fog, heavy rain, thick snowfall).
› Driving around “sharp” bends.
› When fully pressing down the accelerator pedal.
› If there is a fault with the Front Assist system.
› When one of the brake assist systems (e.g. ESC) intervenes.
WARNINGIn the following situations, Front Assist should be switched off for safety rea-
sons.■
When the vehicle is being towed away.WARNING (Continued)■ When the vehicle is on a rolling test bench.■When an undesired activation has repeatedly occurred.■
When on a truck, train or a car ferry service or the like.
CAUTION
Narrow vehicles or vehicles travelling side by side are not detected by Front As-
sist via the radar sensor until they are within the sensor's range. This is especially
true for narrow vehicles, such as motorcycles.
Note
In case of failure of more than one brake light on the vehicle or on the electrically
connected trailer, Front Assist not available.
Radar sensor
Fig. 141
Mounting location of the radar
sensor
First read and observe the introductory information and safety warn- ings on page 154.
The radar sensor » Fig. 141 (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.
155Assist systems
Advance warning
If Front Assist detects a risk of collision with a vehicle ahead, a symbol appears in
the display of the instrument cluster and an acoustic signal is heard » Fig. 142 - .
At the same time, the braking system is prepared for possible emergency braking.
The advance warning may occur when driving between 30 km/h and 210 km/h.
Apply the brakes or avoid the obstacle!
Acute alert
If the driver does not react to the advance warning, Front Assist briefly applies
the brake automatically via an active brake intervention to draw attention to the
potential danger of a collision again.
Automatic Braking
If the driver fails to respond to the acute warning, Front Assist starts to apply the
brakes automatically with increasing stopping power in several stages.
Front Assist can help to mitigate the consequences of a potential accident by
means of a speed reduction.
Brake Support
If the driver does not brake sufficiently in case of an imminent collision, Front As-
sist can increase the braking power, thereby reducing the consequences of a po-
tential accident.
The brake support only occurs as long as the brake pedal is being firmly pressed
down.
CAUTION
The automatic braking interventions by Front Assist can be terminated by press-
ing the clutch or the accelerator, or by moving the steering wheel.
Note
If an automatic brake intervention is triggered by Front Assist, the pressure in the
brake system increases and the brake pedal cannot be operated with the normal
pedal stroke.
Activating/deactivating
First read and observe the introductory information and safety warn-ings
on page 154.
Front Assist is automatically activated each time the ignition is switched on.
Front Assist should only be disabled in exceptional cases.
Activate / deactivate front assist
Front Assist can be activated or deactivated in the Infotainment » Infotainment
manual , chapter Vehicle settings (CAR button) or in the MAXI-DOTDis-
play » page 32 , Menu item wizard .
By disabling the system, the proximity warning system and the advance warning are also deactivated.
Activate/deactivate proximity warning
The proximity warning indicator can be activated/deactivated in the Infotain-
ment » Infotainment manual , chapter Vehicle settings (CAR button) .
The set proximity warning remains active even after stopping and starting the ig-
nition.
Activate/deactivate advance warning
The advance warning can be activated/deactivated in the Infotainment » Info-
tainment manual , chapter Vehicle settings (CAR button) .
The set advance warning remains active even after stopping and starting the ig- nition.
“City”Emergency braking
First read and observe the introductory information and safety warn-ings
on page 154.
The “City”Emergency braking function (From here on referred to only as the emer-
gency brake function) is a component of the Front Assist system.
The emergency brake function assists the driver when driving as follows. › Prepares the brakes for emergency braking prior to a detected danger.
› If the driver fails to respond to a detected danger, an automatic brake action oc-
curs with stopping power that increases in several stages.
The emergency brake function intervenes when driving between about 5 km/h
and 34 km / h.
