Adaptive cruise control
Adaptive cruise control (ACC) is an
enhancement to traditional cruise
control with the additional feature of maintaining a certain distance behind the vehicle ahead.
Adaptive cruise control automatically
decelerates the vehicle when
approaching a slower moving vehicle.
184Driving and operatingIt 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 in front, but will
not exceed the set speed. It may
apply limited braking with activated
brake lights.
The adaptive cruise control can store
and maintain speeds over approx.
15 mph. If following a vehicle ahead
driving slower than 15 mph, the
slower speed will be set. On vehicles
with automatic transmission, the
system can also brake to a stop.
Adaptive cruise control uses a radar
sensor to detect vehicles ahead. If no
vehicle is detected in the driving path, the adaptive cruise control will
behave like a traditional cruise
control.
For safety reasons, the system
cannot be activated before the brake
pedal or clutch pedal has been
depressed once after switching on
ignition.
Adaptive cruise control is mainly
advised to be used on long straight
roads like highways or country roads
with steady traffic. Do not use the
system if it is not advisable to
maintain a constant speed.
Control indicator A 3 109, m 3 109,
C 3 109.9 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 adaptive cruise
control. The control indicator m in the
instrument cluster illuminates white.
Additionally C appears in the Driver
Information Centre.
Activation by setting the speed
Adaptive cruise control can be

timing sensitivity changes the
adaptive cruise control following
distance setting.
Alerting the driver
The vehicle ahead control indicator A illuminates green in the instrument
cluster when the system has detected
a vehicle in the driving path.
The control indicator A changes to
yellow when the distance to a
preceding moving vehicle gets too
short or when approaching another
vehicle too rapidly.Caution
The colour lighting of this control
indicator does not correspond to
local traffic laws on following
distance. The driver bears full
responsibility for maintaining safe
following distance according to
applicable traffic rules, weather
