not be detected. The sensor measures the distance to reflective
surfaces that must have a certain size. The system responds only
after the distance measurement has been made . If a measurement
is not possible, the system cannot respond and wil l not react to a
vehicle or something else up ahead.
O pen ro ad
When the road is clear, the Adaptive Cruise Control works like cruise
control. It main tains a constant target speed specified by the driver.
D riv in g in tr affic
If a slower vehic le driving ahead is detected, the Adaptive Cruise
Control dece lerates (within the limits of the system)::::;,
page 138,
"Driver intervention prompt" and::::;, page 140, "System limitations"
to its speed and after adjusting, tries to maintain the set distance
from the vehicle ahead . The vehicle may temporarily drive s lower
than the set speed while adjusting::::;,
& in "Description" on
page 127.
If the vehicle in front accelerates, Adaptive Cruise Control a lso acce l­
erates up to the speed that you have set.
Sit uation s re qui ring d rive r int erve ntion
In some situations you will have to use the footbrake to s low the
vehicle down in order to keep a safe distance from vehic le in front
of you or to avoid a rear -end collision. In this situation, a symbol
appears and a warning tone sounds::::;,
page 138.
P assing anoth er veh icle
If you move into the pass ing lane and no vehicle is detected ahead,
the Adaptive Cruise Control accelerates to the speed you have set
and ma intains it.
O ve rridin g ACC
You can increase your speed at any time by stepping on the acceler­
ator pedal. After you re lease the acce lerator pedal, the system
adjusts back down to the speed you previously set.
Controls and equip ­
ment R
edu cin g s topping di sta nce
If the radar sensor detects that the distance to the vehicle ahead is
less than defined minimum distance, the brakes are automatical ly
prepared for emergency braking by the driver . The brake pads are
moved very c lose to the brake discs without actual ly braking the
vehic le. This brake assistant feature reacts more quick ly to the
driver's braking, and also works when Adaptive Cruise Control is off.
The stopping distance is reduced as a result of this advance brake
preparation. This function does not perform any emergency brak ing
maneuvers by itself; the driver must always app ly the brakes.
& WARNING
• Never r ely on the d istan ce control feature of ACC alone t o
p re vent re ar- end colli sio ns. Alwa ys be prep ared t o br ake and take
eva sive ac tion to a void colli sio ns and ot her acc ident sit uation s.
• Never allo w the clo sing sp ee d b etwe en you and other vehi cle s
to be so hi gh th at th e Ada ptive Crui se Control may not b e able to
s low your vehicl e safely . If clo sing spe ed i s too h igh , you must
a pp ly the brake s yours elf to reduce the risk of a rea r-end cras h.
[ i ] Tip s
Please note that the amount of acceleration the Adaptive Cruise
Contro l uses depends on the Distance setting selected . DISTA NCE 1
gives you acceleration that is dynamic and sporty . D ISTANCE 4, on
t he o ther hand, gives more moderate acce leration. For more infor ­
mation about the time intervals::::;,
page 133, "How is the distance
(time interval) set?" .
• Please note that if the Adaptive Cruise Control has begun braking
t he vehicle and the driver chooses to brake the vehicle additional ly,
the brakes may feel "hard". This is simply due to the pressure build ­
up of the initial braking .
• 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 pu ll the control lever _.,

With the system 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) .
Pr ess the

After the I SETI button is released, the current speed is stored and
maintained .
The saved speed is now shown in the LED display in the speedom ­

ously set speed is too high for existing road, traffic or weather
conditions.

The distance at which the Adaptive Cruise Control follows 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 ­
dependen t interval. The higher the speed , the greater the safety
interval in feet (meters)
=> &..
For example, if the interval DISTANCE 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 equivalent to a
distance of
131 feet (40 meters) to the vehicle in front.
The distances given here are nominal values. The vehicle speed may exceed or fall short of these target speeds, depending on the
driving situation and the driving style of the vehicle ahead.

& WARNING
Following other veh icles too clo sely increases the risk of a crash
and serious personal injury .
• Following other vehicles too closely , parti cularly at h igher
speeds increases the risk of collisions and serious personal injury.
• 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.

Th e text message EPB activation appears if emergency braking was
manual ly initiated with the Electromechanical Parking Brake (EPB).
The Adaptive Cruise Con trol is turned off . This is accompanied by a
warning tone.
