46
The status display B changes from gray to red.
Information
If speed and distance control was interrupted by
moving the control lever to position 3 ( CANCEL ), it
can only be resumed again when the vehicle is mov-
ing and no stationary objects are detected in front.
ACC warning messages
Takeover prompt in active control mode (ACC
active)
If Adaptive Cruise Control has detected that braking
assistance is required on the part of the driver, a
warning signal sounds and a warning message ap-
pears on the instrument cluster.
For information about Adaptive Cruise Control (ACC)
warning messages:
> Please see chapter "Warning and Information
Messages" on page 293.
WARNING
Inadequate braking
power during automatic
braking
In this case, the deceleration through Adaptive
Cruise Control is insufficient to prevent a collision.
e
Brake immediately.
Exceptional conditions with
Adaptive Cruise Control (ACC)
Adaptive Cruise Control is not available because
Adaptive Cruise Control (ACC) was switched off.
– If the ignition is switched off.
– When PSM is off.
– When driver's door is open and seat belt is not
fastened on the driver side.
– When the electric parking brake is activated.
– If the selector lever is in position N , R and P .
– On steep upward or downward slopes.
Traffic situations in which ve-
hicles cannot be reliably detected
The Adaptive Cruise Control (ACC) radar sensor de-
tects a narrow, conical area in front of the driver's
vehicle.
Depending on the traffic situation and the size of the
vehicle ahead, detection may be restricted or unsta-
ble. The system may brake too late or unexpectedly.
e Particular attentiveness is required while driving.
e Brake if necessary.
Fig. 6: Weaving and narrow vehicles
A – Erratic/weaving vehicles
The vehicle is only detected if it is completely in its
own driving lane.
B – Vehicles with a small cross-section/nar-
row vehicles
will not be detected or will be detected too late.
Fig. 7: Stationary vehicles on bends
C – Entering and exiting bends
Vehicles will not be detected or will be detected too
late, or Adaptive Cruise Control will react to vehicles
in adjacent lanes.
D – Stationary vehicles
A stationary vehicle or obstacle that suddenly ap-
pears in the radar sensor's range, e.g. after a vehicle
ahead changes lanes, may only be detected to a re-
stricted extent by Adaptive Cruise Control (ACC).
