Speed limiter
The speed limiter prevents the
vehicle exceeding a preset maximum speed.
The maximum speed can be set at
speeds above 30 km/h.
The driver can accelerate the vehicle

from the limited speed may occur
when driving downhill.
The preset speed can be exceeded

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. The
adaptive cruise control does not
actively brake the vehicle but uses
engine braking.
If the vehicle ahead accelerates or changes lane, the adaptive cruise
control progressively accelerates the
vehicle to return to the stored set
Page 183 of 287

Driving and operating181speed. If the driver operates the turn
lights to overtake a slower vehicle, the
adaptive 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.
The adaptive cruise control can store set speeds between 40 km/h and
150 km/h. 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 at a speed between
40 km/h and 150 km/h.
A precondition is that adaptive cruise
control is not deactivated in the
vehicle personalisation menu 3 124.
