Speed limiter
The speed limiter prevents the
vehicle exceeding a preset maximum
speed.
The maximum speed can be set at
speeds above 18 mph.
The driver can accelerate the vehicle
up to the preset speed. Deviations
from the limited speed may occur
when driving downhill.
The preset speed can be exceeded
temporarily by pressing the
accelerator pedal firmly.

Adaptive cruise control
Adaptive cruise control is an
enhancement to conventional cruise
control with the additional feature of
maintaining a certain distance behind the vehicle ahead. It uses radar and
camera sensors to detect the vehicles
ahead. If no vehicle is detected in the driving path, the adaptive cruise
control will behave like a conventional
cruise control.
Adaptive cruise control automatically
decelerates the vehicle when
approaching a slower moving vehicle.
It then adjusts the vehicle speed to
follow the vehicle ahead at the
selected following distance. The
Driving and operating163vehicle speed increases or decreases
to follow the vehicle in front, but will not exceed the set speed. It may
apply limited braking with activated
brake lights.
If the vehicle in front accelerates or changes lane, the adaptive cruise
control progressively accelerates
your vehicle to return to the
programmed speed. If the driver
operates a direction indicator to
overtake a slower vehicle, the
adaptive cruise control allows your
vehicle to temporarily approach the
vehicle in front to assist the
overtaking manoeuvre, though never
exceeding the programmed speed.9 Warning
The complete driver attention is
always required while driving with adaptive cruise control. The driver stays fully in control of the vehicle
because the brake pedal, the
accelerator pedal and the cancel
switch have priority over any
adaptive cruise control operation.
Switching on
Press C to switch on the steering
wheel: symbol C is indicated in the
Driver Information Centre. The
system is still not active.
Activation
Adaptive cruise control is switched onmanually at a speed between 25 and
112 mph . For vehicles with automatic
transmission, the automatic selector
lever must be in position D or M.
Setting the speed by the driver
Accelerate to the desired speed and
press toggle switch once briefly to
RES/+ or SET/- . The current speed is
stored and maintained. Accelerator
pedal can be released.
The preset speed can then be
changed by pressing toggle switch to
RES/+ to increase or SET/- to
164Driving and operatingdecrease the speed. Short press
changes speed in small steps, long
press in large steps.
The speed value is indicated in the
Driver Information Centre.
When the cruise control is operating,
Stop & Start is automatically
deactivated.
Adopting speed by the traffic sign assistant
The intelligent speed adaptation
informs the driver when a speed limit
is detected by the traffic sign
assistant. The detected speed limit
can be used as new value for the
cruise control.
Using a camera at the top of the
windscreen, this system detects and
reads speed limit and end of speed
limit signs. The system also takes
account of information on speed limits from of the map data of the navigationsystem.
The function can be deactivated or
activated in the personalisation
menu, 3 104.
If the cruise control is active, the
recognised speed limit will be
displayed in the Driver Information
Centre and MEM illuminates.
The information displayed in the
Driver Information Centre depends on
the display used.
In the Driver Information Centre,
speed limit sign is shown in the
display and MEM illuminates for a few
seconds.
Press MEM on the steering wheel to
request saving of the suggested
speed.
Press MEM on the steering wheel
once more to confirm and save the
new speed setting.This speed is the new value for the
cruise control.
Exceeding the set speed
It is always possible to drive faster
than the selected set speed by
depressing the accelerator pedal.
When the accelerator pedal is
released, the vehicle returns to the
desired distance if a slower vehicle is
ahead. Otherwise it returns to the
stored speed.
Once the system is activated,
adaptive cruise control decelerates or
brakes if it detects a vehicle ahead,
which is slower or closer than the
desired following distance.
If the programmed speed setting is
exceeded, the display of the speed
setting disappears and a message
"Cruise control suspended" is
displayed until the accelerator pedal
is released.
170Driving and operating8'' Colour-Info-Display: Adjust the
alert sensitivity in the settings of the
active emergency braking in the
vehicle personanlisation, 3 104.
The chosen setting will remain until it
is changed. The alert timing will vary
based on vehicle speed. The faster the vehicle speed, the farther awaythe alert will occur. Consider traffic
and weather conditions when
selecting the alert timing.
Deactivation The system can only be deactivated
by deactivating the active emergency
braking in the vehicle personalisation, 3 104.
General information9 Warning
Forward collision alert is just a
warning system and does not
apply the brakes. When
approaching a vehicle ahead too
rapidly, it may not provide you
enough time to avoid a collision.
The driver accepts full
responsibility for the appropriate
following distance based on traffic, weather and visibility conditions.
The complete attention of the
driver is always required while
driving. The driver must always be
ready to take action and apply the
brakes.
System limitations
Forward collision alert is designed to warn on vehicles only, but may reactalso to other objects.
In the following cases, Forward
collision alert may not detect a vehicle ahead or sensor performance is
limited:
● Driving on winding or hilly roads.● During nighttime driving.
● Weather limits visibility, such as fog, rain, or snow
● The sensor in the windscreen orthe radar unit behind the front
bumper are blocked by snow, ice,
slush, mud, dirt etc.
● The windscreen is damaged or affected by foreign items, e.g.
stickers.
Active emergency braking
Active emergency braking can help to reduce the damage and injury from
crashes with vehicles, pedestrians
and obstacles directly ahead, when a
collision can no longer be avoided
either by manual braking or by
steering. Before the active
emergency braking applies, the driver
is warned by the Forward collision
alert 3 169 or the Front pedestrian
protection alert 3 173.
The feature uses various inputs (e.g.
camera sensor, radar sensor, brake
pressure, vehicle speed) to calculate
the probability of a frontal collision.
178Driving and operatingThe driver must control acceleration,
braking and gear shifting, while
steering is done automatically. The driver can take control at any time by
gripping the steering wheel.
It may be necessary to move forwards and backwards more than once.
Instructions are given in the Info-
Display 3 101.
Advanced parking assist can only be activated when driving forwards.
Advanced parking assist is always
combined with front-rear parking assist.
The system has six ultrasonic parking
sensors each in both the rear and
front bumper.
