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.

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.

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.

lected than on dry roads.
Special driving conditionsFig. 139
Special conditions: Cornering / narrow vehicles or vehicles travel-
ling side by side
Fig. 140
Special conditions: Lane changes of other vehicles / stationary ve-
hicles
First read and observe the introductory information and safety warn-
ings
on page 148.
The following and similar situations require special attention of the driver.
When cornering
When driving around long bends the ACC may respond to a vehicle in the adjacent
lane » Fig. 139 -
. Your own vehicle is regulated with respect to this vehicle and
will no longer respond to the vehicle ahead.
In such cases, control should be disabled by accelerating, applying the brake or
pressing the button on the operating lever .
» Fig. 138 on page 151 .
153Assist 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

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.
Front Assist: no sensor view.
Stop the car, switch off the engine and clean the sensor or eliminate the obstacle
causing the lack of“visibility”. Should Front Assist still be unavailable after the en-
gine is restarted, consult a specialist garage for help.WARNING■ If you suspect that the sensor is damaged, deactivate Front Assist. 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 Front Assist 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!
WARNINGThe sensor may not be able to distinguish all objects correctly under certain
circumstances. You should therefore not use Front Assist in the following ca-
ses - risk of accidents!■
When driving through places where metal objects (such as metal buildings,
railroad tracks, etc.) can be found.
■
When driving through very divided and enclosed spaces (such as large-ca-
pacity garages, car ferries and the like.)
CAUTIONRemove the snow with a brush and the ice with a solvent-free de-icer.

Front Assist assists the driver while driving in the following ways:
› 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 brake action is
performed.
Front Assist can work only if the following basic conditions are met. Front Assist is enabled.
TCS is enabled » page 137, Brake assist systems .
The vehicle is traveling forwards at a speed of more than approx. 5 km/h.
proximity warning (dangerous proximity)
If a safe time interval to the vehicle ahead is exceeded, the display of the instru- ment cluster shows the symbol » Fig. 142 -
.
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.
