Driving and operating171Driver assistance
systems9 Warning
Driver assistance systems are
developed to support the driver
and not to replace his attention.
The driver accepts full
responsibility when driving the
vehicle.
When using driver assistance
systems, always take care
regarding the current traffic
situation.
Cruise control
The cruise control can store and
maintain speeds of approx. 30 to
200 km/h. Deviations from the stored
speeds may occur when driving uphill or downhill.
For safety reasons the cruise control cannot be activated until the foot
brake has been operated once.
Activating in first gear is not possible.
Do not use the cruise control if it is not advisable to maintain a constant
speed.
With automatic transmission, only
activate cruise control in automatic
mode.
Control indicator m 3 106.
Switching on Press button m, control indicator m in
instrument cluster illuminates white.
Activation
Accelerate to the desired speed and
turn thumb wheel to SET/-: the
current speed is stored and
maintained. Control indicator m in
instrument cluster illuminates green.
Set speed is indicated on midlevel or
uplevel display near m symbol.
Accelerator pedal can be released.
Vehicle speed can be increased by depressing the accelerator pedal.
When the accelerator pedal is
released, the previously stored speed
is resumed.
Cruise control remains activated
while gearshifting.
174Driving and operating
vehicle speed increases or decreasesto follow the vehicle in front, but willnot exceed the set speed. It may
apply limited braking with activated
brake lights.
The adaptive cruise control can store
and maintain speeds over approx.
25 km/h and brakes automatically to
follow a slower vehicle driving ahead
to a minimum speed of 15 km/h. On vehicles with automatic transmission
the system brakes to a stop.
Adaptive cruise control uses a radar
sensor to detect the vehicles ahead.
If no vehicle is detected in the driving path, the adaptive cruise control will
behave like a traditional cruise
control.
For safety reasons, the system
cannot be activated before the brake
pedal has been depressed once
since switching on ignition. Activation
in first gear is not possible.
Adaptive cruise control is mainly
advised to be used on long straight
roads like highways or country roads
with steady traffic. Do not use the
system if it is not advisable to
maintain a constant speed.
Control indicator A 3 106, m 3 106,
C 3 106.9 Warning
The complete driver attention is
always required while driving with adaptive cruise control. The driver stays fully in control of the vehicle
because the brake pedal, the
accelerator pedal and the cancel
switch have priority over any
adaptive cruise control operation.
Switching on
Press button C to switch on adaptive
cruise control. The control indicator
m or C in the instrument cluster
illuminates white.
Activation by setting the speed Adaptive cruise control can be
activated between 25 km/h and
180 km/h.
Accelerate to the desired speed and
turn thumb wheel to SET/-, the
current speed is stored and
176Driving and operating
large increments, or activate
repeatedly SET/-: speed decreases in small increments.
If the vehicle is driven with adaptive
cruise control active much slower
than the desired speed, e.g. because
of a slower vehicle ahead, then the
current speed can be stored and
maintained by turning the thumb
wheel to SET/-.
Resume stored speed
If the system is switched on but
inactive, then turn thumb wheel to
RES/+ at a speed above 25 km/h to
resume the stored speed.
Full speed range adaptivecruise control on vehicles withautomatic transmission Full speed range adaptive cruise
control will maintain a following gap
behind a detected vehicle and slow
your vehicle to a stop behind that
vehicle.When the vehicle ahead drives away
within two minutes, turn thumb wheel
to RES/+ or operate the accelerator
pedal to resume full speed range
adaptive cruise control.
If the stopped vehicle ahead begins to move forward and full speed range
adaptive cruise control has not
resumed, the green illuminated
vehicle ahead control indicator A will
flash and a warning chime will sound
as a reminder that the vehicle ahead
is pulling away.
When the vehicle ahead stops for
more than two minutes, the electric
parking brake will apply automatically and the full speed range adaptive
cruise control is deactivated. In this
event, drive the vehicle normally by
operating the accelerator pedal. Turn
thumb wheel to RES/+ at a speed
above 25 km/h to resume full speed
range adaptive cruise control.9 Warning
When full speed range adaptive
cruise control is deactivated or
cancelled, the vehicle will no
longer be held at a stop and can
start to move. Always be prepared to manually apply the brake to hold the vehicle stationary.
Do not leave the vehicle while it is being held at a stop by the full
speed range adaptive cruise
control. Always move selector
lever to park position P and switch
off the ignition before leaving the
vehicle.
Setting the following distance
When adaptive cruise control detects
a slower moving vehicle in the driving path, it will adjust the vehicle speed tomaintain the following distance
selected by the driver.
The following distance can be set to
near, medium or far.

Deactivation
Adaptive cruise control is deactivated by the driver when:
■ button y is pressed,
■ brake pedal is applied,
■ clutch pedal is depressed for more than four seconds,
■ gear selector lever of automatic transmission is moved to N.
The system is also automatically
deactivated when:
■ vehicle speed accelerates above 190 km/h or slows down below15 km/h (on vehicles with automatic transmission it slows down to a stop
without deactivating within
two minutes),
■ Traction Control system is operating for more than
20 seconds,
■ Electronic Stability Control is operating,■ there is no traffic and nothingdetected on the road sides for
several minutes. In this case there
are no radar echoes and the sensor
may report that it is blocked,
■ collision imminent braking is applying the brakes,
■ radar sensor is blocked by an ice or
water film,
■ fault is detected in the radar, engine
or brake system.
Additionally the system is
automatically deactivated on vehicles with automatic transmission (full
speed range adaptive cruise control)
when:
■ Electric parking brake is applied,
■ vehicle is being held to a stop by the
system for more than two minutes,
■ vehicle stops and a door is opened.
When adaptive cruise control is
deactivated automatically, the control indicator m or C illuminates white
and a warning symbol is displayed as a pop-up in the Driver Information
Centre.
The stored speed is maintained.
