& WARNING
• Always pay attention to traffic even when the cruise control is
switched on . You are always responsible for your speed and the
distance between your vehicle and other vehicles.
• For safety reasons, the cruise control should not be used in the
city, in stop -and -go traffic, on twisting roads and when road condi
tions are poor (such as ice , fog , gravel , heavy rain and hydro
planing ) -risk of accident.
• Turn off the cruise control temporar ily when entering turn
lanes, highway exit lanes or in constru ction zones.
• Please note that inadvertently "rest ing " your foot on the accel
erator pedal cau ses the cruise control not to brake . This is because
the cruise control is overridden by the driver's acceleration . ..

& WARNING (continued)
• Never use the cruise control when driving off-road or on
unpaved roads. The Cruise control is intended for use only when
the vehicle is being operated on paved roads , and is not suitable
for use off -road or on unpaved roads .
[ i J Tips
The cruise control cannot maintain a constant speed when driving
downhill. The vehicle will accelerate under its own weight. Down
shift to a lower gear or use the brakes to slow down. •
Changing speed
-Press lever in the 0 or O direction ~ page 149, fig. 157
to increase or decrease your speed.
- Release the lever to save that speed.
Change speed in increments of 1 mph (1 km/h) by lightly pressing
the lever . If you keep the lever pressed down, you will alter your
speed in 5 mph (10 km/h) increments.
You can also press the accelerator pedal down to increase your
speed, e.g. if you want to pass someone. The speed you saved
earlier will resume as soon as you release the accelerator pedal.
If, however, you exceed your saved speed by 5 mph (10 km/h) for
longer than 5 minutes, the cruise control will turn off temporarily.
The symbol will go out but the saved speed will be retained. •
Presetting your speed
You can preset your desired speed while the vehicle is not
moving.
- Turn on the ignition.
- Pull lever into position
G) ~ page 149, fig. 157.
- Press the lever in the
0 or O direction to increase or
decrease your speed.
- Release the lever to save that speed.
This function makes it possible, for example, to save the speed you
want before driving on the highway. Once on the highway, activate
the cruise control by pulling the lever toward
G). •
Swit ching th e syst em off
Temporary deactivation
- Press the brake pedal, or
- Press the lever into posit ion

~ page 149, fig. 157, or
- Drive for longer than 5 minutes at more than 5 mph
(10 km/h) above the stored speed .
Switching off completely
- Press lever into position
0 (clicked into place), or
- Switch the ignition off.
The system retains the saved speed if you deactivate the cruise
control temporarily . To resume the saved speed, release the brake
pedal and pull the lever to position

Storing speed
With the system switched on the speed is stored as follows :
- Drive at the speed you want.
Press the ( SET] button
::::> fig. 162 to store the desired
speed.
After the I SET I button is released, the current speed is stored and
maintained . If you are driving at a speed below 20 mph (30 km/h) ,
the minimum speed setting of 20 mph (30 km/h) will be set.
The saved speed is now shown in the LED display in the speedom eter by one or two illuminated red light diodes~
page 161. At the
same time , the saved speed is also shown for a short time in the
Information line~

[ i J Tips
For safety reasons, the stored speed is erased when the ignition or
the ACC is turned off. •

& WARNING
Improper use of the Adaptive Cruise Control features and inatten
tion can lead to an accident causing serious personal injury.
• It is dangerous to use the "RESUME" feature when the previ
ously set speed is too high for existing road, traffic or weather
conditions.
• Always read and heed the information and WARNINGS =>

[ i] Tips
You can increase your speed at any time by stepping on the acceler

Setting distance
Increasing distance
-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 ::::>

tained. The ACC system is not switched off, and increased attention
to the traffic situation is absolutely necessary. The following may be
reasons why the message
ACC functionality limited appears:
• The ACC sensor is dirty . The ACC system is not reacting, or is not
reacting correctly, to moving vehicles up ahead in your lane of
travel.
• There may be very light traffic on and there is nothing that marks
the side of the road (for example, guard rails, traffic signs, trees). As
soon as a moving vehicle up ahead is detected again, ACC becomes
active again and the message disappears .
The ACC sensor is located behind the area to the right of the front
license pla te . If the ACC sensor is dirty or blocked, clean the area to
restore system operation.
Parking brake !
The text message Parking brake ! appears, when the parking brake
is applied. ACC is turned off. A warning tone sounds as a reminder.
Stationary object ahead
The text messag e Stationary object ahead appears, when you want
to activate the system and there is a stationary vehicle or an object
immediately in front of you.
Gradient too steep
The text message Gradient too steep appears when the maximum
gradient for proper ACC operation has been exceeded. Adaptive
Cruise Control is turned off. A warning tone also sounds as a
reminder.
ACC off: manual control!
The text message ACC off: manual control! appears after the vehicle
has been brought to a standstill by the Adaptive Cruise Control. In
this case you must depress the brake pedal to prevent the vehicle
from rolling. A warning tone sounds as a reminder .
