• Setting short distan ces to the traffic ahead reduces the time
and distance available to bring your vehicle to a safe stop and
makes it even more necessary to pay close attention to traffic .
• Always select a speed and distance to traffic ahead that is safe
and appropriate under the prevailing traffic , road , weather and
lighting conditions .
• Never rely on the distan ce control feature of ACC alone to
p revent rear-end collisions . Alw ays be prepared to brake and take
evasive action to avoid collisions and other accident situations.
• Never allow the closing speed between you and other vehicles
to be so high that the Adaptive Cruise Control may not be able to traf

tained. The ACC system is not switched off, and increased attention
to the traffic situation is absolutely necessary. The following may be
reasons why the message
ACC functionality limited appears:
• The ACC sensor is dirty . The ACC system is not reacting, or is not
reacting correctly, to moving vehicles up ahead in your lane of
travel.
• There may be very light traffic on and there is nothing that marks
the side of the road (for example, guard rails, traffic signs, trees). As
soon as a moving vehicle up ahead is detected again, ACC becomes
active again and the message disappears .
The ACC sensor is located in the area under the front license plate.
If the ACC sensor is dirty or blocked, clean the area to restore system
operation.
ACC not available
The text message ACC not available appears, for example, if the
temperature of the brakes is excessive . Adaptive Cruise Control is
temporarily not available. A warning tone sounds as a reminder.
ACC not available!
The text message ACC not available! appears in the event of a
malfunction. Adaptive Cruise Control is turned off. A warning tone
sounds as a reminder. Have the system inspected by a qualified
dealership .
ACC sensor blocked !
The text message ACC sensor blocked ! appears when the ACC
System can no longer accurately detect vehicles moving up ahead
in your lane of travel. Adaptive Cruise Control is turned off. A
warning tone a lso sounds as a reminder.
To decide whether it is necessary to switch off the ACC (ACC sensor blocked
!) or if it is only a temporary condition (ACC Functionally
limited), the system will also takes into consideration the outside
temperature and/or the windshield wiper operation.
The ACC sensor is dirty or blocked (e.g. leaves, snow) . The
ACC sensor is located in the area under the front license plate .
If the ACC sensor is dirty or blocked, clean the area to restore system
operation.

In certain situations, the braking power of the Adaptive Cruise
Control is no t enough to maintain an adequate distance to the
vehicle up ahead . In these situations, the Adaptive Cruise Contro l
calls the driver to take action.
The
driv er in tervention pr omp t alerts you visually and audibly to
take over.
• A red vehicle is shown in the instrument c luster display
=>
page 138, fig. 134 .
• The text
DISTANCE! appears in the status line .
• The indicator light~'" '~ in the speedometer b links red.
• A warning tone sounds .
[ i J Tip s
• If the Adaptive cruise control initiates braking, the hydraulic
brake system is under pressure . Therefore, the brake peda l distance
is shorter and the pedal "fee ls" harder .
• Adaptive Cruise Contro l is switched off after pressing the foot
brake. The speed saved up this point can be resumed .
• To resume the saved speed, release the brake pedal and press
the control lever=>
page 132, "Turning Adaptive Cruise Cont ro l off
temporarily" .
• I f you use the accelerator to go faster than the speed of the
vehicle ahead of you, the
drive r inte rv e ntion prompt will not be
accompanied by a warning signal.
• If the speed you previously set is exceeded, the indicator light in
