Adaptive Cruise Control
Speed and distance control system
Applies to vehic les : with Adaptive C ruise Cont rol
Description
The Adaptive Cruise Control driver assistance pr ogram is
a combined speed and distance control system .
Fig. 123 Fro nt
bu mper: Pos it io n of
r adar senso r
Adaptive Cruise Control can help make driving more re laxed and
less t iring, particula rly during long trips on interstates or other
highways that are generally straight .
Set ACC to maintain a constant, legal travel speed between 20 and
95 mph (30 -150 km/h) that is appropriate for prevailing traffic
conditions. Select a following distance to the vehicle ahead and ACC
w ill adjust your speed to maintain that distance .
Adaptive Cruise Contro l has technical limitations that you must
know, so please read this section carefully, understand how the
system works and use it proper ly at all times .
How does it work ?
You can operate the Adaptive Cruise Control using the lever on the
steering wheel column=> page 130, "How is the speed stored?" a nd
=> page 133, "How is the distance (time interval) set? ".
Con tro ls and eq uip­
ment
Driver inf ormation
Important information is brought up in the speedometer and in the
instrument cluster display as the ve hicle is being driven
=> page 135, "Driver information" .
What is important for y ou to kn ow
The Adaptive Cruise Control is set with system -specified limits; that
is, as a driver, you will have to adj ust the speed and distance to the
vehic le ahead in some instances=> page 138 , "Driver intervention
prompt" and=> page 140, "System limita tions" .
& WARNING
Improper u se of the Adapti ve Crui se Control can c ause colli sion s,
oth er ac cident s and s eriou s per sonal injur y.
• Alway s reme mber that the Adapt ive Cruise Control ha s limit s -
it will not slow the veh icle do wn or maintain the set dis tance
w hen you drive to w ard s an obst acle or something o n or ne ar the
road th at is not moving, such as vehicle s stopped in a traffi c jam ,
a stalled or disabled vehicle .
• Alwa ys remember th at the Adaptive Cru ise Control can not
dete ct a vehicle th at is driving to ward s you in your tr affi c lane and
th at it can not dete ct n arr ow vehi cles su ch as motorcycl es and
bicycle s.
• Never dr ive at speed s th at ar e too fa st for traff ic, road and
we ather co nd ition s.
• The Adaptive Cru ise Control cannot slow or brake th e vehi cle

& WARNING (continued)
• 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.
• Never rest your foot on the accelerator pedal, especially when
the Adaptive Cruise Control is being used. Pressure on the acceler ­
ator will override the ACC braking function and prevent the brakes
from being applied when ACC detects a situation when the brakes must be applied .
• Never use 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
vision can be reduced by rain, snow and
heavy road spray. These and similar conditions can prevent vehi ­
cles 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 moving ahead of you in
traffic.
• Always turn off Adaptive Cruise Control when entering turn
lanes, exit lanes and construction zones or in similar situations
because the vehicle will automatically accelerate to the stored
speed when the road ahead is clear.
• To prevent unintended operation, always switch ACC off when
it is not being used.
[ i) Tips
• For safety reasons, the stored speed is deleted when the ignition
is turned off .
• The Electronic Stabilization Program (ESP) and the Anti-Slip
Regulation (ASR) cannot be deactivated when the Adaptive Cruise
Control is switched on. If the ESP and the Anti-Slip Regulation (ASRI has been deactivated and you then switch on the
Adaptive Cruise
Control, the ESP function will also be activated automatically.
• Damage caused by accidents and some minor collisions can
affect the radar sensor settings and cause the system to malfunc­
tion or switch off completely.
• The radar sensor cover is heated. In winter conditions, you
should still check before driving to make sure it is free of ice and
snow. If necessary, clean the area near the radar sensor carefully
=>
page 127, fig. 123.
• To ensure that the radar sensor is not blocked, foreign objects
(e.g. stickers, larger license plate mounts, add -on parts) must not
cover the area near the radar sensor=>
page 127, fig. 123. The area
near the radar sensor must not be painted, either.

How does Adaptive Cruise Control work?
Vehicles traveling ahead are detected with the aid of a
radar sensor.

ciple diagram : Radar
sensor measurement

Adaptive Cruise Control uses a radar sensor in the front of the
vehicle=> fig. 124. Th e system has limitations=>

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 _.,
