& WARNING (continued)
the veh icle s afely when you follow another vehicle too closely.
Alway s rem ember that the Adaptive Cruise Control has a braking
powe r that is only about 30 % of the vehicle's maximum braking
ability. The automatic braking function cannot bring th e ve hicle to
a sudden or emergency stop . Always 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
slow your vehicle safely. If closing speed is too h igh, you must
apply the brake s your self to reduce the ri sk of a rear-end cra sh .
• Never rest your foot on the accelerator pedal , especially when
the Adaptive Crui se Control is being used. Pressure on the acceler­
ator will overr ide the ACC braking function and prevent the brakes
from being applied when ACC detects a situation when the brake s
must be applied .
• Never u se Adaptive Cruise Control when you cannot drive safely
at a steady speed, including on city streets , on winding roads or
when road conditions are poor (for example , on ice, gravel, in fog ,
heavy rain or on wet roads that increase the risk of hydroplaning ).
• The radar sensor's
vi sion can be redu ced by rain, snow and
heavy road spray. These and similar conditions can prevent vehi­
cle s up ahead from being accurately detected and in some cases
they may not be detected at all. Do not use ACC when the radar
sensors cannot accurately detect vehicles mo ving ahead of you in
traffic .
• Always turn off Adaptive Crui se Control when entering turn
lanes, exit lanes and con struction zones or in similar situat ions
because the vehicle will automatically accelerate to the stored
speed when the road ahead i s clear .
• To prevent unintended operation , always switch ACC off when
it is not being used .

(I] Tips
•
For safety reaso ns, t he stored speed is deleted when the igni tion
is turned off .
• T he Elect ronic Stabilization Program (ESP) and the Ant i- Slip Regu ­
lat ion (ASR) cannot be deactivated when the Adaptive Cruise Contro l
is sw itched on . If the ES P and t he Anti -S li p Reg ula tio n (ASR) has been
deactivated and you then switch on the Adaptive Cruise Control, the
E S P fu nction will also be a ctivated au toma tically.
• Damage cause d by accidents and some minor coll is ions can affect
t he radar se nsor se ttings and cause the syste m to malfunction o r
switch off completely .
• Th e radar sensor cover is heated. In win ter conditions, you should
st ill chec k befo re dr iv ing to make sure it is free of ice and snow. If
ne cessa ry, clean the area nea r the rada r sensor carefully ::}

How does Adaptive Cruise Control work?
Vehicles traveling ahead ore detected with the aid of a
radar sensor.
Fig. 132 Basic prin­
ciple diagram: Radar
sensor measurement
range
Adaptive Cruise Control uses a radar sensor in the front of the vehicle
=>
page 138, fig. 132 . The system has limitations=> page 149.
Things that are not moving in your lane and in your direction of travel
w ill 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 will not react to a
vehicle or someth ing else up ahead.
Open road
When the road is clear, the Adaptive Cru ise Control works like cruise
control. It maintains a constant target speed specified by the driver .
Driving in traffic
If a slower veh icle driv ing ahead is detected, the Adaptive Cruise
Control decelerates (within the limits of the system)=>
page 148,
"Driver intervention prompt" and => page 149, "System limitations"
to its speed and after adjusting, tries to ma inta in the set distance
from the vehicle ahead. The vehicle may temporarily drive slower
than the set speed whi le adjusting=>
& in "Descr iption" on
page 136.
If the vehicle in front accelerates, Adaptive Cruise Control also accel­
erates up to the speed that you have set.
If the vehicle ahead slows to a stop, ACC w ill slow your vehicle down
and to a complete stop if this is possible within the system's limits
and capabilities . ACC will not make an emergency stop. The text
message
ACC off: manual control! appears in the instrument cluster
display. Once the vehicle stops, you must depress the brake pedal to
prevent the veh icle from moving forward or "creeping". Depressing
the brake pedal turns off ACC. When the vehicle ahead accelerates
you can reactivate ACC =>
page 141, as soon as your vehicle has
reached a speed of 1 mph (2 km/h) .
Situations requiring driver intervention
In some situations you will have to use the footbrake to slow the
vehicle down in order to keep a safe distance from vehicle in front of
you or to avoid a rear-end collision. In this situation, a symbol
appears and a warning tone sounds=>
page 148.
Passing another vehicle
If you move into the passing lane and no vehicle is detected ahead,
the Adaptive Cruise Control accelerates to the speed you have set and
maintains it.
Overriding ACC
You can increase your speed at any time by stepping on the acceler ­
ator pedal. After you release the accelerator pedal, the system
adjusts back down to the speed you previously set.
Reduc ing stopping distance
If the radar sensor detects that the distance to the vehicle ahead is
less than defined minimum distance, the brakes are automatically
prepared for emergency braking by the driver. The brake pads are
moved very close to the brake discs withou t actually bra king the
vehicle. This brake assistant feature reacts more quickly to the driver's braking, and also works when Adaptive Cruise Control is off.
The stopping d istance is reduced as a result of this advance brake .,_

preparation. Th is function does not p erfo rm any e mergency braki ng
man eu ver s by its elf; th e dr iver m ust alway s app ly the b ra kes .
& WARNING
If ACC initiates a braking maneuver, the brake pedal will be
retracted . Interference with the brake pedal can prevent ACC from
slowing the vehicle down and cause a crash and serious personal
injury .
• Never put anything in the driver's footwell or let anything fall
into it. An object in the driver 's footwell can interfere with the
pedals and prevent the accelerator from being used to override
ACC or prevent ACC from being switched off when the brake pedal
is depressed and also prevent the vehicle from being slowed down
or stopped.
• Only use floor mats that keep the area around the pedals free
and that can be securely fastened to the footwell.
• Never drive with your foot underneath the brake pedal.
• Always read and heed the information and WARNINGS~
& in
" Description " on
page 136.
& WARNING
• Never rely on the distance control feature of ACC alone to
prevent rear-end collisions. Always 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 slow your vehicle safely. If closing speed is too high , you must
apply the brakes yourself to reduce the risk of a rear-end crash.

& WARNING
Following other v ehicles too clo sely increases the risk of a crash
and serious per sonal injury.
• Following other vehicles too closely, particularly at higher
speeds in crea ses the ri sk of collisions and seriou s personal injury.
• Setting short distances to the traffic ahe ad reduces the time
and distance avail able to bring your vehicl e to a safe stop and
makes it even more necessary to pay close attent io n to t raffic.
• Always select a speed and distance to traffic ahead that is safe
and appropriate under the pre vailing traffic, road , weathe r and
lighting conditions.
• Never rely on the distance control feature of ACC alone to
prevent rear-end collisions . Always be pr epared to brake and take
evasive action to a void collisions and other accident situations.
• Never allow the closing sp eed b etween you and other vehicles
to be so high that the Adapti ve Cruise Control may not be able to
s low your vehicle safely . If closing speed is too high, you must
