128Driving and operatingThe adaptive cruise control is
deactivated automatically in the
following cases:
● The brake pedal is depressed.
● The vehicle accelerates above 112 mph (manual and automatic
transmission) or slows down
below 19 mph (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 afew 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 mountainroads, 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 thevisibility. In case of sensor
blockage, clean the sensor
cover.
● Do not use the system when the spare wheel is in use.
System limits9 Warning
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.
