Driver assistance systems are
developed to support the driver
and not to replace the driver's
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 above 40 km/h.
Additionally at least the third gear
must be engaged on manual
transmission, on automatic
transmission position D or the second
or a higher gear in position M must be
selected.
Deviations from the stored speeds may occur when driving uphill or
downhill.
The system maintains the vehicle
speed at the preset speed by the
driver, without any action on the
accelerator pedal.
The preset speed can be exceeded
temporarily by pressing the
accelerator pedal firmly.
The status and preset speed is
displayed in the Driver Information Centre.
Do not use the cruise control if it is not advisable to maintain a constant
speed.
Control indicator m 3 100.
160Driving and operatingAdopting speed by the traffic sign
assistant
The intelligent speed adaptation
informs the driver when a speed limit
is detected by the traffic sign
assistant. The detected speed limit
can be used as new value for the
cruise control.
Using a camera at the top of the
windscreen, this system detects and
reads speed limit and end of speed
limit signs. The system also takes
account of information on speed limits from the navigation map data.
The function can be deactivated or
activated in the personalisation menu
3 106.
If the cruise control is active, the
recognised speed limit will be
displayed in the Driver Information
Centre and MEM illuminates.
The displayed information depends
on the Driver Information Centre
version.
In the Driver Information Centre,
speed limit sign is shown in the
display and MEM illuminates for a few
seconds.Press MEM on the steering wheel to
request saving of the suggested
speed.
Press MEM on the steering wheel
once more to confirm and save the
new speed setting.
This speed is the new value for the
cruise control.
Exceeding the set speed
Vehicle speed can be increased by
depressing the accelerator pedal.
When the accelerator pedal is
released, the previously stored speed is resumed.
Deactivation of the functionality Press Ñ, cruise control is in pause
mode and a message is displayed.
The vehicle is driven without cruise
control.
Cruise control is deactivated, but not
switched off. Last stored speed
remains in memory for later speed

programmed speed value.
Driving and operating163Switching off the system
Press ß, the speed limiter mode is
deselected and the speed limit
indication extinguishes in the Driver
Information Centre.
Pressing m to activate cruise control
deactivates speed limiter.
The preset speed remains in the
memory when the ignition is switched
off.
Fault
In the event of a speed limiter fault,
the speed is cleared resulting in
flashing of the dashes.
The speed limiter may not operate correctly if traffic signs do not comply with the Vienna Convention on Road
Signs and Signals.
Adaptive cruise control
The adaptive cruise control is an
enhancement to the conventional
cruise control with the additional
feature of maintaining a certain
following distance to the vehicle
ahead. It uses radar and camerasensors to detect the vehicles ahead.
If no vehicle is detected in the driving path, the adaptive cruise control will
behave like a conventional cruise
control.
The adaptive cruise control
automatically decelerates the vehicle
when approaching a slower moving
vehicle. It then adjusts the vehicle
speed to follow the vehicle ahead at
the selected following distance. The
vehicle speed increases or decreases
to follow the vehicle ahead, but will
not exceed the set speed. It may
apply limited braking with activated
brake lights.
If the vehicle ahead accelerates or changes lane, the adaptive cruise
control progressively accelerates the
vehicle to return to the stored set
speed. If the driver operates a the turn lights to overtake a slower vehicle, the
adaptive cruise control allows the
vehicle to temporarily approach the
vehicle ahead to help passing it.
However, the set speed will never be
exceeded.The adaptive cruise control can store set speeds over 30 km/h for manual
transmission. If the vehicle ahead is
moving too slowly and the selected
following distance cannot be
maintained anymore, a warning
chime is given and a message is
displayed in the Driver Information Centre. The message prompts thedriver to take back control of the
vehicle. On vehicles with automatic
transmission, the system can brake
the vehicle until a full stop.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 button
Ñ have priority over any adaptive
cruise control operation.
164Driving and operatingSwitching on the system
Press C, the symbol C is indicated in
the Driver Information Centre. The
system is still not active.
Activation of the functionality by
setting the speed
The adaptive cruise control has to be
switched on manually at a speed
between 30 km/h and 180 km/h. For
vehicles with automatic transmission, the automatic selector lever must be
in position D or M.
Accelerate to the desired speed and
move the thumb wheel to SET/-. The
current speed is stored and
maintained.
The speed value is indicated in the
Driver Information Centre.
When the adaptive cruise control is
operating, the stop-start system is
automatically deactivated.
Overriding set speed It is always possible to drive faster
than the selected set speed by
depressing the accelerator pedal.
When the accelerator pedal is
released, the vehicle returns to the
stored speed. If a slower moving
vehicle is ahead, the following
distance selected by the driver is
restored.
If the set speed is exceeded, the
indicated speed setting flashes in the Driver Information Centre and a
warning message appears.9 Warning
Accelerating by the driver
deactivates automatic braking by
the system. This is indicated as a
pop-up warning in the Driver
Information Centre.
Driving and operating165Increasing speedWith the adaptive cruise control
active, hold the thumb wheel moved
to RES/+ or briefly move to RES/+
repeatedly: The speed increases continuously or in small increments.
Reducing speed
With the adaptive cruise control
active, hold the thumb wheel moved
to SET/- or briefly move to SET/-
repeatedly: The speed decreases
continuously or in small increments.
Resuming stored speed Move the thumb wheel to RES/+ at a
speed above 30 km/h. The adaptive cruise control is activated with the
stored set speed.
Taking over the speed limit from
the traffic sign assistant
The intelligent speed adaptation
informs the driver when a speed limit
is detected by the traffic sign
assistant. The detected speed limit
can be taken over as new set speed
for the adaptive cruise control.With the camera at the top of the windscreen, this system detects and
reads speed limit and end of speed
limit signs. The system also takes
account of information on speed limits
from the navigation map data.
The function can be activated or
deactivated in the personalisation
menu 3 106.
If the adaptive cruise control is active, the recognised speed limit will be
displayed in the Driver Information
Centre and MEM illuminates.
In the Driver Information Centre,
speed limit sign is shown in the
display and MEM illuminates for a few
seconds.
Press MEM on the steering wheel to
request saving of the suggested
speed.
Press MEM on the steering wheel
once more to confirm and save the
new speed setting.
This speed limit is now the new set
speed of the adaptive cruise control.Adaptive cruise control on
vehicles with automatic
transmission
For vehicles with automatic
transmission, adaptive cruise control
allows to maintain the selected
distance behind a stopping vehicle
until a complete stop is reached.
If the system has stopped your
vehicle behind another vehicle, then
the set speed is replaced by a green
control indicator .. This symbol
notifies, that the vehicle is hold
automatically in stop position.
If the stopped vehicle ahead was
stopped for a longer time and then
begins to move forward, the green
illuminated vehicle ahead control
indicator . will flash and a warning
chime will sound as a reminder to check traffic before resuming.
When the vehicle ahead drives away,
press the accelerator pedal until
30 km/h and then move the thumb
wheel to SET- or RES+ to resume
adaptive cruise control. If the vehicle
stays stopped for more than five
minutes or if the driver's door is
Driving and operating167The adaptive cruise control is
deactivated automatically when:
● The brake pedal is depressed.
● The vehicle accelerates above 180 km/h or slows down below
30 km/h.
● The electric parking brake is applied.
● The Traction Control system or Electronic Stability Control is
deactivated or operating.
● The selector lever of automatic transmissions is neither in D nor
in M.
● A fault is detected in the Electronic Stability Control or theradar system.
Switching off the system Press C, the adaptive cruise control
mode is disabled and the adaptive
cruise control indication extinguishes
in the Driver Information Centre.
Pressing ß to activate the speed
limiter deactivates adaptive cruise
control.Switching off the ignition deletes the
stored set speed.
Driver's attention ● Use the adaptive cruise control carefully on bends or mountain
roads, as it can lose the vehicle
ahead and needs time to detect it again.
● Do not use the system on slippery roads as it can create
rapid changes in tyre traction
(wheel spinning), so that you
could lose control of the vehicle.
● Do not use the adaptive cruise control during rain, snow or
heavy dirt, as the radar sensor
can be covered by a water film,
dust, ice or snow. This reduces or suppresses completely the
visibility. In case of sensor
blockage, clean the sensor
cover.
● Do not use the system when the spare wheel is in use.System limits9Warning
The system's automatic brake
force does not permit hard braking and the braking level may not be
sufficient to avoid a collision.
● After a sudden lane change, the system needs a certain time to
detect the next preceding
vehicle. So if a new vehicle is
detected, the system may
accelerate instead of braking.
● The adaptive cruise control does ignore the oncoming traffic.
● The adaptive cruise control does not consider pedestrians and
animals for braking and driving
off.
● The adaptive cruise control considers stopped vehicles only
at low speed.
Driving and operating177behind the vehicle. It informs and
warns the driver by giving acoustic
signals and display indication.
It uses two different acoustic warning
signals for the front and rear
monitoring areas, each with a
different tone frequency.
The system operates with ultrasonic
parking sensors in the rear and front
bumper.
Activation
In addition to the rear parking assist,
the front parking assist is triggered
when an obstacle is detected in front
and the speed of the vehicle is below 10 km/h.
The system is ready to operate when
the LED in the parking assist button
¼ is not illuminated.
When the system is deactivated, the
LED in the button illuminates.
Indication
The system warns the driver with
acoustic signals against potentially
hazardous obstacles in front of the
vehicle and behind the vehicle.
Depending on which side of the
vehicle is closer to an obstacle, you
will hear acoustic warning signals in the vehicle on the respective side.
The interval between the sounds
becomes shorter as the vehicle gets
closer to that obstacle. When the
distance is less than approx. 30 cm,
the sound is continuous.
Additionally, the distance to rear and
front obstacles is displayed by
changing distance lines in the Info Display 3 103.
If the vehicle stops for more than
three seconds in a forward gear, if
automatic transmission is in P or if no
further obstacles are detected, no
acoustic warning signals are given.
