the veh icle safely when you follow another vehicle too closely .
Always remember that the Adaptive Crui se Control has a braking
power th at is only about 30 % of the vehicle 's maximum braking
ability . The automatic braking function cannot bring the vehicle to
a sudden or emergen cy stop . Always be prepared to bra ke and
take evasive action to avoid collisions and other accident situa ­
tions .
• 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 ri sk of a rear -end crash .
• Never rest your foot on the accelerator pedal , especially when
the Adapt ive Cruise Control is being used . Pressure on the a cceler ­
ator will override the ACC braking function and prevent the brakes
from being appl ied when ACC detects a situation when the brakes
must be applied.
• Never use Adapt ive 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 r ain or on wet roads that increase the risk of
hydroplaning
I.
• 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 veh icles 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 automati cally accelerate to the stored
speed when the road ahead is clear.
• To prevent unintended operation , always switch ACC off when
it is not be ing used .
Controls and equip ­
ment
[ i ] Tips
• For sa fety reasons , the sto red speed is de leted w he n th e ig nit ion
is turned off.
• The E lectronic Stabilization Program (ESP) and the Anti -Slip
R egu lation (ASR) cannot be deacti vated when the Adaptive Cruise
Co ntrol is sw itc hed on . If the ESP and the Anti-Slip Regula tion (AS R)
has been deactivated and you then switch on the Adaptive C rui se
Contro l, t he ESP func tion w ill also be act iva ted automat ica lly .
• Damage caused by accidents an d so me mino r co llisions can
affect t he radar sensor sett ings and cause the sys tem to ma lfun c­
tion or switch off completely.
• The radar sensor cover is heated. In winter conditions, you
should stil l check before driving to make sure it is free of ice and
s n ow. If necessary, clean the area near t he radar sensor carefully
~ page 15 2, fig. 159 .
• To ensure that the radar sensor is not blocked, foreign objects
(e .g. stickers, la rger l icense plate mount s, add -on pa rts) must not
cove r th e area near t he radar sensor~ page 152, fig. 159. The area
nea r the rada r sensor must not be painted, either .

How does Adaptive Cruise Control work?
Vehicles traveling ahead are detected with the aid of a
radar sens or.
Fig. 160 Bas ic p rin­
ci pl e diagra m: R adar
s en sor measur eme nt
ra nge
Adaptive Cruise Contro l uses a radar sensor in the fron t of the
vehic le=> fig. 160. The system has limitations=>
page 165. Things
t hat are not moving in your lane and in your direction of travel will
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
vehic le or something else up ahead.
Op en ro ad
When the road is clear, the Adaptive Cruise Contro l works like cruise
control. It maintains a constant target speed specified by the driver.
D rivi ng in t raffi c
If a slower vehicle driving ahead is detected, the Adaptive Cruise
Control dece lerates (within the limits of the system)=>
page 164,
"Driver intervention prompt" and=> page 165, "System l imitations"
to its speed and after adjusting, tries to maintain the set distance
from the vehicle ahead. The vehicle may temporarily drive slower
than the set speed wh ile adjusting=>
& in "Description" on
page 752 .
If the vehicle in front acce lerates, Adaptive Cruise Control a lso accel­
era tes up to the speed that you have set .
If the vehicle ahead s lows to a stop, ACC wi ll slow your vehicle down
and to a complete stop if this is possible within the system's limits
and capabil ities . ACC will not make an emergency stop. The text
message
ACC off : manu al c ontro l! appears in the instrument c luster
display . Once the veh ic le stops, you must depress the brake peda l
to prevent the vehicle from moving forward or "creeping" .
Depressing the brake pedal turns off ACC. When the veh ic le ahead
acce lerates you can reactivate ACC =>
page 157, as soon as your
vehic le has reached a speed of 1 mph (2 km/h).
S ituati ons re quir in g dri ver int erve ntion
In some situations you will have to use the footbrake to slow the
vehic le 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 164.
Passing anoth er v ehicl e
If you move into the passing lane and no vehicle is detected ahead,
the Adap tive Cruise Contro l accelerates to the speed you have set
and maintains it.
Ov erriding A CC
You can increase your speed at any time by stepping on the acceler ­
ator pedal. After you re lease the accelerator peda l, the system
adjusts back down to the speed you previously set.
Redu cin g stopping di stan ce
If the radar sensor detects that the distance to the vehicle ahead is
less than defined minimum d istance, the brakes are automat ically
prepared for emergency braking by the driver. The brake pads are
moved very c lose to the brake discs without actually braking the
vehic le. This brake assis tant feature reacts more quickly to the
driver's braking, and also works when Adap tive Cruise Contro l is off.
The stopping distance is reduced as a result of this advance brake .,_

preparation. This function does not perform any emergency braking
m aneuv ers by i tse lf ; t he driver m ust alw ays app ly the b rake s.
& 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 swit ched off when the brake pedal
is depressed and also prevent the vehicle from being slowed down
or stopped .
• Only u se 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 152.
& 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 Adapt ive 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 cra sh.

• Please not e th at if th e Ada ptive Cru ise Control has begun bra king
the vehicle and the driver chooses to brake th e vehicle additionally,
t he brakes may fe e l "har d". Th is is simply due t o th e pr essu re build ­
up of the initial braking .

-Push the slider switch once to the right 0 ~ fig. 166. The
distance currently set is shown for 3 seconds in the instrument cluster display.
Cruise Control accelerates to reach the desired speed if no slower
vehicle ahead is detected.
& WARNING
Improper use of the Adaptive Cruise Control can cause collisions,
other accidents and serious personal injuries.
• Never resume the stored speed if the speed is too high for
prevailing road, traffic or weather conditions.
[ i ] Tips
When the system is turned off temporarily, the speed set at that
time is stored. •
- Push the slider switch again to the right 0 to increase
the distance by one step.
Reducing distance
Push the slider switch once to the left Q. The distance
currently set is shown for 3 seconds in the instrument
cluster display.
- Push the slider switch
again to the left Oto decrease the
distance by one step .
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
dependent interval. The higher the speed, the greater the safety
interval in feet (meters)

& WARNING
Following other vehicles too closely increases the risk of a crash
and serious personal injury .
• Following other vehi cles too closely , particularly at h igher
speeds increases the risk of colli sions 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 , weather and
lighting conditions .
• Never rely on the distan ce control feature of ACC alone to
prevent rear-end collisions. Always be prepared to brake and take
evasive action to avoid collisions and other acc ident situations .
• Never allow the closing speed between you and other vehicles
to be so h igh 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 .
• Always select a greater following distance to the vehicle ahead
on wet roads than on dry roads .
• Always re ad and heed the informat ion and WARNINGS ::::>
