on the scale. The green area represents the distance set. When
approaching slowly, the arrow moves from the
gray zone to the green
zone on the scale.
• Driver intervention prompt: When approach ing rapidly, the
arrow serves as an early warning signal. If the distance se lected is
exceeded or possibly not reached, the arrow moves into the
red zone
on the scale. In certain driving situations, you as the driver will have
to take action=>

ACC functionality Limited
The message ACC functional ity limited appears when the ACC
System does not detect any moving vehicles up ahead in your lane of
travel for a longer period of time. During this time, the distance to
moving veh icles in your lane of travel up ahead is not being main

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 aga in, ACC becomes
active again and the message disappears.
Th e 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
operat ion.
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 warn ing tone
so unds as a reminder. Have the system inspected by a qualified deal
ership.
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 also
so unds 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 Functiona lly
limited), the system w ill also takes into consideration the outside
temperature and/or the windshield wiper operation .
Th e 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 bloc ked, clean the area to restore system
operation .
EPB activation
The text message EPB activation appears if emergency braking was
man ua lly initiated with the Electromechanical Parking Brake (EPB).
The Adaptive Cruise Control is turned off . Th is is accompanied by a

The driver intervention prompt calls on the driver to take

Adaptive Cruise Control -
----------------
In certain situations, the braking power of the Adaptive Cruise
Control is not enough to maintain an adequate distance to the vehicle
up ahead. In these situations, the Adaptive Cruise Control calls the
driver to take action.
The
driver intervention prompt alerts you visually and audibly to take
over.
• A red vehicle is shown in the instru ment cluster display
=>
page 130, fig. 118.
• Th e text
DISTANCE! appears in the status line.
• The indicator light
c:::>uuc:::> in the speedometer blinks red.
• A warning tone sounds .
[I) Tips
• If the Adaptive cruise control initiates braking, the hydraulic brake
system is under pressure . Therefore, the brake pedal distance is
shorter and the pedal "feels" harder .
• Adaptive Cruise Control 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 124, "Turning Adaptive Cruise Control off
temporarily".
• If you use the accelerator to go faster than the speed of the
vehicle ahead of you, the
driver intervention prompt will not be
accompanied by a warn ing s ignal.
• If the speed you previously set is exceeded, the indicator light in
the speedometer will switch
off .•

System limitations

General information
The radar sensor has limits that the driver must know to
be able to use ACC properly.
The Adaptive Cruise Control works within limits that are also related
to radar sensor range and sight distance. In some situations ACC may
reac t unusually or late from the driver's poin t of view . Therefore,
always be attentive to what is happen ing around you and a lways be
ready to intervene, if necessary:
• when driving around curves=>

& WARNING
The radar sensor's function and range can be reduced by rain, snow

detected or may not be detected at all.
• Always pay careful attention to the traffic situation and be

makes use of the braking effect of the engine w ithout the need to
shift down manually .
If you are driving in hills and mounta ins, the transmission will contin
uously adjust the gear ratio to the road grade. If you press the brake
pedal when driving downhill, the transmission will downshift auto
matically. This increases the brak ing effect of the engine.
If the cruise control is on when you are traveling downhill, the trans
mission will automatica lly select a lower gear ratio in order to main
