With th e syst em switched on the speed is stored as follows:
- Drive at the speed you want. The speed must be between
20 and 95 mph (30 and 150 km/h) .
- Press the
!SETI button => fig . 110 to store the desired
speed .
After the I SET I button is released, the current speed is stored and
maintained .
The saved speed is now shown in the LED disp lay in the speedometer
by one or two illuminated red light diodes~

Push the slider switch
again to the left Oto decrease the
distance by one step.
Th e d istance at wh ic h the Adaptive Cruise Control fo llows a vehicle in
front is determined by
time intervals. A time interval to a vehicle in
front is established and maintained. This produces a speed-depen­
dent interval. The higher the speed, the greater the safety interval in
feet (meters)
=> & .
For example, if the interval DI STA NCE 3 is set, a vehicle in front is
followed at a time interval of 1.8 seconds.
For a speed of 50 mph (80 km /h ) this would be equ ivalent to a
distance of 131 feet (40 m ete rs) to the veh icle in front .
T he distances giv en here are nominal va lues. The vehicle speed may
exceed o r fall short of these target speeds , depending on the driving
situation and the d riving style of the vehicle ahead .

& WARNING
Following other vehicles too closely increases the risk of a crash
and serious personal injury .
• Following other vehicles too closely , particularly at higher
s peeds increase s the risk of collisions and serious personal injury.
• Setting short distances 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 , weathe r and
lighting conditions.
• Never rely on the distance control feature of ACC alone to
prevent rear-end collisions . Always be prepared to brake and take
ev asive action to avoid collisions and other accident situations .
• Never allow the closing spe ed between you and other vehicles
to be so high that the Adaptive Cruise Control may not be able to more dynamically or more com
fortab ly when accelerating a nd
bra king. The set ting is se lec ted t hrough the MMI m enu Adaptive

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
tained . The ACC system is not sw itched off, and increased attent ion .,,

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
wa rning tone.

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
A pp lies to ve hicle s: with Ad apti ve Crui se Con tro l
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:

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