Driving and operating
■ Electronic Stability Control is
operating,
■ there is no traffic and nothing
detected on the road sides for
several minutes. In this case there
are no radar echoes and the sensor
may report that it is blocked,
■ collision imminent braking is
applying the brakes,
■ radar sensor is blocked by an ice or
water film,
■ fault is detected in the radar, engine
or brake system.
When adaptive cruise control is
deactivated automatically, the control
indicator
m
illuminates white and a
warning symbol is displayed as a pop-
up in the Driver Information Centre.
The stored speed is maintained.

Warning
When adaptive cruise control is
deactivated, the driver must take
over full brake and engine control.
Switching off
Press button
C
to switch off adaptive
cruise control. The control indicator
m
extinguishes. The stored speed is
deleted.
Switching off the ignition also
switches off adaptive cruise control
and deletes the stored speed.
Driver's attention
■ Use adaptive cruise control
carefully on bends or mountain
roads, as it can lose the vehicle
ahead and need 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.
■ Do not use 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
the visibility. In case of sensor
blockage, clean the sensor cover.
System limits
■ 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.
