The distance at which the adaptive cruise con­ trol follows a vehicle in front is determined by
time interva ls. A time interval to a vehicle in
front is estab lished and maintained. Th is pro­
duces a speed-dependent interval. The higher
the speed, the greater the safety interva l in

For example, if the interval DISTANCE 3 is
set, a vehicle in front is fo llowed at a
time in­
terval
of 1.8 seconds.
For a speed of
50 mph (80 km /h ) this wo uld
be equivalent to a distance of

T he distances given here are nom inal va lues .

_&. WARNING
-
Following other vehicles too closely in ­
creases the risk of a crash and serious per­
sonal injury .
- Following other vehicles too closely, par­
ticu larly at higher speeds increases the
risk of coll is ions and serious personal in­
jury.
- 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 traff ic, road, weath­
er and lighting conditions.
- Never rely on the distance control fea­
ture of ACC a lone to prevent rear-end col­
lis ions. Always be prepared to b rake and
take evasive act io n to avoid co llisions
and other ac cident situations.
- Never allow the clos ing speed between
yo u a nd other vehicles to be so h igh that
the adaptive cruise control may not be
able to slow your vehicle safe ly . If clos­
ing speed is too high, yo u m ust app ly the
brakes yourself to reduce the risk of a
rear-end crash.
- Always select a greater following dis­
tance to the veh icle ahead on wet roads
than on dry roads.
- Always read and heed the information
and WARNINGS

ACC not available
The text message ACC not available appears,
for example, if the temperature of the brakes
i s excessive. Adaptive cruise control is tempo­
rarily not available. A warning tone sounds as
a reminder .
ACC not available!
The text message ACC not available! appears
in the event of a malf uncti on. Adaptive cruise
control is tu rned off . A warning tone sounds
as a reminder. Have the system inspected by a
qua lified dealership.
ACC sensor blocked !
The text message ACC sensor blocked ! ap­
pears when the ACC System can no longer ac­
curately detect vehicles moving up ahead in
your lane of travel. Adaptive cr uise control is
turned off. A warning tone also sounds as a re­ minder.
To decide whether it is necessary to switch off
the ACC (ACC sensor blocked
!) or if it is only a
temporary condition (ACC Functionally limit­
ed), the system will a lso takes into cons idera­
tion the outside temperature and/or the wind­
shield wiper operation .
The ACC sensor is dirty or blocked (e.g. leaves,
snow).
The ACC sensor is loca ted behind the area to
the right of the front license plate . If the ACC
sensor is dirty or blocked, clean the area to re­
store system operat ion.

ACC functionality limited
T he message ACC functionality limited ap­
pears when the ACC System does not detect
any moving vehicles up ahead in your lane of
trave l for a longer period of time . During t his
time, the distance to moving vehicles in your
lane of travel up ahead is not being main­
ta ined . 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 d irty. The ACC system is
not reacting, or is not reacting co rrectly, to
moving vehicles up ahead in your lane of
travel.
- There may be very light traffic on and there
is noth ing that marks the side of the road
(for examp le, guard ra ils, traffic signs,
t rees). As soon as a moving vehicle up ahead
is detected again, ACC becomes active again
and the message disappears.
T he ACC senso r is located behind the area to
the right of the front license p late.
If the ACC
sensor is dirty or blocked, clean the area to re ­
store system operation.
Parking brake!
The text message Parking brake! appears,
whe n the parking brake is applied. ACC is
turned off. A warning tone sounds as a re­
minder.
Stationary object ahead
T he text message Stationary object ahead ap­
pears, whe n you want to activate the system

this case you must depress the brake pedal to
prevent the vehicle from rolling . A warning

The driver intervention prompt calls on the
driver to toke over the situation.

p romp t
In certain situations, the braking power of the
adapt ive cr uise control is not enough to main­
tain an adequate distance to the vehicle up
ahead . In these situat ions, the adaptive cruise
contro l calls the dr iver to take action.
The
driver intervention prompt alerts you vis­
ually and audib ly to take over.
- A red vehicle is shown in the instrument
cluster display ¢

line .
- T he indicator light- in the speedome­
ter blinks red.
- A warning tone sounds .
(D Tips
-Adaptive cruise contro l is switched off af­
ter pressing the footbrake. The speed
saved up this point can be resumed.
- To resume the saved speed, release the
brake pedal and press the control lever
¢ page 118, 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 w ill
not be accompanied by a warn ing s ign al.
- If the speed you previously set is exceed­
ed, the indicator light in the speedome ­

System limitations
General information
Applies to vehicles: with adaptive cruise control
The radar sensor has limits that the driver
must know to be able to use ACC properly.
The adaptive cruise control works within lim­
its that are also related to radar sensor range
and s ight distance . In some situations ACC
may react unusually or late from the driver's
point of v iew. Therefore, a lways be attent ive
to what is happening around you and always be ready to intervene, if necessary:
- when driving around curves ¢page 125
- when vehicles up front are not in line with
you r vehicle ¢ page 125
- when other vehicles are changing lanes
¢ page 126
- when other vehicles are difficult to detect
¢ page 126
- when vehicles up ahead are not moving or
obstacles are in your travel lane ¢page 126
A WARNING
The radar sensor's function and ra nge can
be reduced by rain , snow and heavy spray.
Moving veh icles up ahead may not be
prompt ly detected or may not be detected
at all.
- Always pay ca reful attention to the traf­
fic s ituation and be ready to intervene
and be rea dy to take comp lete cont rol
whenever necessary.
When driving around curves
Applies to vehicles: with adaptive cruise co ntrol
Fig. 1 39 Vehicle enter ing a cu rve

Fig. 140 Vehicle leaving a curve
Entering a curve
When enter ing a curve, the adaptive cruise
control may react to a vehicle in the next lane
and apply the brakes in your vehicle
¢ fig. 139. The braking action ca n be over rid­
den by depressing the ac ce lera tor pedal.
Leaving a curv e
At the end of very long curves, ACC's predic­
tive lane reading can cause ACC to react to an­
other vehicle in the next lane and apply the
brakes on your vehicle~ fig . 140. The braking
action can be overr idden by depressing the ac­
ce le rator pedal.
Vehicles offset to one side
App lies to vehicles: with adaptive cruise control
Fig. 141 Vehicle traveling ah ead outside the detect ion
r ange of the radar sensor
Vehicles moving up ahead but offset in the
lane ca nnot be detected by ACC until they are
in sensor range.

126 Adaptive cruise control
Lane changes by other vehicles
Applies to vehicles: with adaptive cruise control
Fig. 142 A vehicle changes la nes
Vehicles that cut into your lane a short dis­
tance in front of you cannot be detected by
ACC until they are in sensor range .
Vehicles that are difficult to detect
Applies to vehicles: with adaptive cruise control
Fig . 143 Two-wheeled vehicle driving ahead
Some vehicles moving up ahead in your lane
of travel are difficult to detect, for example
two-wheeled vehicles, vehicles with high
ground clearance, loads sticking out the back.
Vehicles like this are often detected late or in
some situations not at all .
Stationary vehicles
Applies to vehicles: with adaptive cruise contro l

If a vehicle that has been detected by ACC ex­
its the highway or sheers out into the neigh­
boring travel lane, and there is a stationary
vehicle ahead of that vehicle, ACC w ill not de­
tect or react to that stationary vehicle
