Adaptive cruise control The adaptive cruise control is an
enhancement to the conventional
cruise control with the additional
feature of maintaining a certain
following distance to the vehicle
ahead.
128Driving and operatingstart moving. Be always prepared
to manually apply the brake to hold the vehicle stationary.
Do not leave the vehicle while it is being held at a stop by adaptive
cruise control. Always move
selector lever to park position P
and switch off the ignition before leaving the vehicle.
Setting the following distance
When adaptive cruise control detects a slower moving vehicle in the driving
path, it will adjust the vehicle speed to maintain the following distance
selected by the driver.
The following distance can be set to
close (1 bar), normal (2 bars) or far (3 bars).
If the engine is running and the
adaptive cruise control is enabled
(grey) or avtive (green), you can
modify the following distance setting:
Press V, the current setting is
shown in the Driver Information
Centre.
Press V again to change the
following distance: The new setting is displayed in the Driver Information
Centre.
The selected following distance is
indicated by full bars in the adaptive
cruise control page.9 Warning
The driver accepts full
responsibility for the appropriate
following distance based on traffic, weather and visibility conditions.
Following distance must be
adjusted or the system switched
off when required by the prevailing
conditions.
Detecting the vehicle ahead
If the system detects a vehicle in the
driving path, the adaptive cruise
control symbol displayed in the Driver
Information Centre changes: - is
changed to w.
Deactivation of the functionality
Press i, the adaptive cruise control
is in pause mode and a message is
displayed. The vehicle is driven
without adaptive cruise control.
The adaptive cruise control is
deactivated, but not disabled. The
last stored set speed remains in
memory for later usage.

deactivated automatically in the
following cases:
● The brake pedal is depressed.
Driving and operating129● The vehicle accelerates above180 km/h (manual and automatic
transmission) or slows down
below 30 km/h (manual
transmission).
● The electric parking brake is applied.
● The traction control system or electronic stability control is
deactivated or operating.
● The selector lever of automatic transmissions is neither in D nor
in M.
● A fault is detected in the electronic stability control or the
radar system.
● Immediately after the clutch pedal has been depressed or a
few seconds after the clutch
pedal has been depressed
(depending on the manual
transmission).
Switching off the system
Press w, the adaptive cruise control
mode is disabled and the adaptive
cruise control indication extinguishes
in the Driver Information Centre.Pressing 5 to activate the speed
limiter deactivates adaptive cruise
control.
Switching off the ignition deletes the
stored set speed.
Driver's attention ● Use the adaptive cruise control carefully on bends or mountain
roads, as it can lose the vehicle
ahead and needs time to detect it
again.
● Do not use the system on slippery roads as it can create
rapid changes in tyre traction
(wheel spinning), so that you
could lose control of the vehicle.
● Do not use the adaptive cruise control during rain, snow or
heavy dirt, as the radar sensor
can be covered by a water film,
dust, ice or snow. This reduces or suppresses completely the
visibility. In case of sensor
blockage, clean the sensor
cover.
● Do not use the system when the spare wheel is in use.System limits9Warning
The system's automatic brake
force does not permit hard braking and the braking level may not be
sufficient to avoid a collision.
● After a sudden lane change, the system needs a certain time to
detect the next preceding
vehicle. So if a new vehicle is
detected, the system may
accelerate instead of braking.
● The adaptive cruise control does ignore the oncoming traffic.
● The adaptive cruise control does not consider pedestrians and
animals for braking and driving
off.
● The adaptive cruise control considers stopped vehicles only
at low speed.
132Driving and operatingAs a safety measure, do not use the
system if the brake lights are faulty.
Do not use the system if the front
bumper is damaged.
Active emergency braking
Active emergency braking can help to reduce the damage and injury from
crashes with vehicles and
pedestrians directly ahead, when the
driver does not actively take action
either by manual braking or by
steering. Before the active
emergency braking applies, the driver
is warned by the forward collision
alert.
Forward collision alert 3 135
Front pedestrian protection 3 137
Active emergency braking can be
deactivated in the vehicle
personalisation 3 77. If deactivated,
m illuminates in the instrument
cluster and a warning message is
displayed in the Driver Information
Centre. When ignition is switched on next time, system is activated.The feature uses various inputs (e.g.
camera sensor, radar sensor, brake
pressure, vehicle speed) to calculate
the probability of a frontal collision.9 Warning
This system is not intended to
replace the driver responsibility for driving the vehicle and looking
ahead. Its function is limited to
supplemental use only to reduce
the vehicle speed before a
collision.
The system may not react to
animals. After a sudden lane
change, the system needs a
certain time to detect the next
preceding vehicle.
The driver must always be ready
to take action and apply the brakes and steer to avoid collisions.
9 Warning
The usage of a license plate
support may have an impact on
the proper operation of the radar
unit and may limit sensor
perfomance. Vehicles or
pedestrians driving or walking
ahead may not be detected by the
system.
Do not use a a license plate
support to ensure proper system
functionality.
Functionality
Depending on the vehicle
configuration and the detected
objects, there are several operational speed ranges.
On vehicles equipped only with front
camera, the active emergency
braking operates from 5 km/h to 80 km/h when a vehicle has been
detected.
On vehicles equipped with radar
sensor and front camera, the active
emergency braking operates from
5 km/h to 140 km/h when a vehicle
has been detected.
Active emergency braking only works when the seat belts of the front
passengers are fastened.
