If the vehicle in front accelerates, Adaptive Cruise Control a lso accel­
erates up to the speed tha t you have set.
Si tu ation requiring d river interv ention
In some situa tions you will have to use the footbrake to s low the
vehic le down in order to keep a safe distance from vehicle in front
of you or to avoid a rear -end collision . In this situa tion, a symbol
appears and a warning tone sounds~
page 146.
P ass ing an ot her 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.
O ve rrid e
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.
[ i ) Tips
Please note that the amount of acceleration the Adaptive Cruise
Control uses depends on the Distance se tt ing selected. DISTANCE 1
gives you acceleration that is dynamic and sporty . DISTANCE 4 , on
t he other hand, gives more moderate acce leration . For more infor ­
mation about the time intervals~
page 140, "H ow is the distance
(time interval) set?" .
• Please note that if the Adap tive Cruise Contro l has begun braking
t he vehicle and the driver chooses to brake the vehicle additiona lly,
the brakes may feel "hard". This is s imply due to the pressure build­
up of the initial braking.
• Adaptive Cruise Contro l is switched off after pressing the foot­
b rake . The speed saved up this point can be resumed . To resume the
saved speed, release the brake pedal and press the contro l lever
:;) page 139, "Turning Adaptive Cru ise Contro l off temporarily" .•

20 and 95 mph (30 and 150 km/h).
Press the !S ETI button ~

desired speed.
Af te r the (S ET) button is released, the current speed is stored and
maintained .
The saved speed is now shown in the LED display in the speedom­
eter by one or two illuminat ed red light diod es =>
page 143. At the
same time, the saved speed is also shown for a short time in the
Information line=>

[ i ) Tips
For safety reasons , the stored speed is dele ted when the ignition is
turned off. •

Changing stored speed
The speed can be changed without touching the acceler ­
ator or brake pedal.
Fig. 133 Control lever:
Changing speed
Increasing speed
- Press the lever up briefly upwards 0 ~ fig. 133. USA
models: the speed increases by about 2.5 mph. Canada
models: speed will increase by one mark on the speed­
ometer scale.
- Press the lever upwards
0 and hold it. As long as you
hold the control switch down, the light diode display in
the speedometer LED display in the speedometer moves
forward and the speed is increased.
Reducing speed
- Press the lever downwards briefly Q. USA models: the
speed decreases by 2.5 mph. Canada models: speed will
decrease by one mark on the speedometer scale.
- Press the lever downwards
O and hold it. As long as you
hold the control switch down, the light diode display in
the speedometer LED display moves backward and the
speed is reduced .
After releasing the control switch, the system regulates the speed to
the value just set.
After each adjus tmen t, the n ewly-set speed is shown for a short
time in the Information line=>
page 145.
[ i ) Tips
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. A new desired
speed can be stored at any time by pressing the
( S ETI button
=> page 137, fig. 132. •

- To shut off the control w ith the save function, either
depress the brake pedal, or
- Press the con trol sw itch in the direction of the arrow@
~ fig. 134.
Reactivating control
- To resume the saved speed, release the b rake pedal and
press the control switch in the d irection of the arrow

& 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.

How is the distance (time interval) set?
Distance can be set in four stages.
Fig . 135 Co ntrol lev er:
Se tting d is ta nce
Increasing distance
- Pus h the slid er switch once to the r ig ht G) ::::;> fig. 135. The
dista nce currently set is shown for 3 seconds in the
inst rument cluster d isp lay.
Push the s lid er sw itch
again to the right G) to increase
the d istanc e by o ne s tep .
Reducing distance
Push th e sli de r sw itch once to the left Q. The distance
current ly set is shown for 3 seconds in the instrument
cluster disp lay.
- Pu sh the s lider swi tch
again to the left Q to dec rease t he
dista nce by one step.
The distance at which the Adap tive Cruise Control follows a vehicle
in front is determ ined by
time intervals. A time interva l to a vehicle
in front is estab lished and mai nta ined . This produces a speed ­
dependent interval. The higher the speed , the greater the safety
interval in yards (meters)~& .
For example, i f the interval
DISTANCE 3 is set, a vehicle in front is
followed at a
t i me interval of 1.8 seconds .
Fo r a speed of
55 mph (100 km /h ) this would be equiva lent to a
distance of
4 8 yard s (50 mete rs ) to the vehicle in front.
The distances given here are specified values. The vehicle speed may exceed or fa ll shor t of these target speeds, depending on the
driving situation and the driving sty le of the v ehicle ahead.

How your vehicle responds when accelerating and following other
vehicles with ACC operating can be adapted to your personal wishes
through different driving programs. Depending on which driving
program and which distance you choose, your vehicle will respond more
dynamically or more comfortably when accelerating and
braking. The setting is selected through the MMI menu Adaptive
Cruise Control =>
page 147, "MMI settings".

When setting the distance, the driver is responsible for adhering
to the respective national and country-specific regulations.

& WARNING (continued)
• 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 use good judgment and select a safe following distance
for the traffic, road and weather conditions.
[ i ] Tips
The distance setting is reset to the factory default DISTANCE 3 the
next time the ignition is turned on.•
