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

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. It uses a camera at the top of
the windscreen and a radar sensor in
the front bumper 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.
The 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
vehicle speed increases or decreases
to follow the vehicle ahead, but will
not exceed the set speed. It may
apply limited braking with activated
brake lights.
If the vehicle ahead accelerates or changes lane, the adaptive cruise
control progressively accelerates the
vehicle to return to the stored set
speed. If the driver operates the turn
Page 182 of 289

180Driving and operatinglights to overtake a slower vehicle, theadaptive cruise control allows the
vehicle to temporarily approach the
vehicle ahead to help passing it.
However, the set speed will never be
exceeded.
If the vehicle ahead is moving too
slowly and the selected following
distance cannot be maintained
anymore, a warning chime is given
and a message is displayed in the
Driver Information Centre. The
message prompts the driver to take
back control of the vehicle. On
vehicles with automatic transmission,
the system can brake the vehicle until a full stop.
The adaptive cruise control can store
set speeds over 25 mph and 93 mph.
Additionally at least the third gear
must be engaged on manual
transmission, on automatic
transmission position D / A or the
second or a higher gear in position M must be selected.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 and the accelerator pedal have priority
over any adaptive cruise control operation.
Switching on the system
The adaptive cruise control can be
switched on manually at a speed
between 25 mph and 93 mph.
A precondition is that adaptive cruise
control is not deactivated in the
vehicle personalisation menu 3 123.Turn to Cruise, the symbol Q and a
message are displayed in the Driver Information Centre. The system is still not active.

Adaptive cruise control on
vehicles with automatic
transmission
For vehicles with automatic
transmission, adaptive cruise control
allows to maintain the selected
distance behind a stopping vehicle
until a complete stop is reached.
If the system has stopped your
vehicle behind another vehicle, then
the set speed is replaced by a green
control indicator .. This symbol
notifies, that the vehicle is hold
automatically in stop position.
If the stopped vehicle ahead was
stopped for a longer time and then
begins to move forward, the green
illuminated vehicle ahead control
indicator . will flash and a warning
chime will sound as a reminder to
check traffic before resuming.
When the vehicle ahead drives away,
press the accelerator pedal until
19 mph and then press SET/+ or
SET/- to resume adaptive cruise
control. If the vehicle stays stopped
for more than 5 minutes or if the
driver's door is opened and the
driver's seat belt is unfastened, then
the electric parking brake is applied
automatically to hold the vehicle.
