& WARNING
• Never turn off the engine until the vehicle has come to a
complete stop.
• The brake booster and servotronic only work when the engine
is running. With the ignition turned off, you have to apply more
force when steering or braking. Since you cannot steer and stop
normally, this can lead to accidents and serious injuries.
• For safety reasons, you should always park your vehicle with
the selector lever in P. Otherwise, the vehicle could inadvertently roll away.
• After the engine has been switched off, the radiator fan can
continue to run for up to 10 minutes -even with the ignition
switched off. It can also switch on again after some time if the
coolant temperature rises as the result of a heat buildup or if the
engine is hot and the engine compartment is additionally heated
by the sun's rays.
0 Note
If the engine has been under heavy load for an extended period,
heat builds up in the engine compartment after the engine is
switched off -there is a risk of damaging the engine. Allow the
engine to run at idle for about 2 minutes before switching it off. •

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 .,_

-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 ::::>
