systems9 Warning
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 some manual
transmissions. 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.Switching on the system

Activation of the functionalitySetting speed by the driver
Accelerate to the desired speed and
move thumb wheel once briefly to
SET/- . The current speed is stored
and maintained. Accelerator pedal
can be released.
The preset speed can then be
changed by moving thumb wheel to RES/+ to increase or SET/- to
decrease the speed. Move thumb wheel repeatedly to change speed in
small steps, move and hold to change speed in large steps.
Speed value is indicated in the Driver
Information Centre.
Adopting speed by the speed limit
recognition
The intelligent speed adaptation
informs the driver when a speed limit
is detected by the speed limit
recognition. The detected speed limit
can be used as new value for the
cruise control.
Using the camera at the top of the
windscreen, this system detects and
reads speed limit and end of speed
limit signs.
With active cruise control the
recognised speed limit will be
displayed in the Driver Information
Centre and MEM illuminates if the
difference between set speed and
speed limit is more than 9 km/h.
Press MEM on the steering wheel to
request saving of the suggested

Press MEM on the steering wheel
once more to confirm and save the
new speed setting.
This speed is the new value for the

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 i, cruise control is in pause
mode and a message is displayed.
The vehicle is driven without cruise
control.
Cruise control is deactivated, but not

Cruise control is deactivated
automatically in the following cases:
● The brake pedal is depressed.
● Vehicle speed is below 40 km/h.
● The traction control system or electronic stability control is
operating.● The selector lever is in N
(automatic transmission) or the
first or second gear (on some
manual transmissions) is
engaged.
● Immediately after the clutch pedal has been depressed or a
few seconds after the clutch
pedal has been depressed
(depending on the manual
transmission).
Resume stored speed
Move thumb wheel to RES/+ at a
speed above 40 km/h. The stored
speed will be obtained.
Switching off the system
Press v, the cruise control mode is
deselected and the cruise control
indication extinguishes in the Driver
Information Centre.
Pressing 5 to activate the speed
limiter deactivates cruise control.
Switching off the ignition cancels any
programmed speed value.Fault
In the event of a cruise control fault,
the speed is cleared resulting in
flashing of the dashes.
The speed limit recognition may not
operate correctly if traffic signs do not comply with the Vienna Convention
on Road Signs and Signals.
Speed limiter
The speed limiter prevents the
vehicle from exceeding a preset
maximum speed.
The maximum speed can be set at
speeds above 30 km/h.
The driver can accelerate the vehicle
up to the preset speed. Deviations
from the limited speed may occur
when driving downhill.
The preset speed can be exceeded
temporarily by pressing the
accelerator pedal firmly.
The status and preset speed limit are
displayed in the Driver Information

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.
Page 127 of 229

Driving and operating125
It uses radar and camera sensors 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 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 the
driver 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.

Activation of the functionalitySetting speed by the driver
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.
The preset speed can then be
changed by moving thumb wheel to
RES/+ to increase or SET/- to
decrease the speed. Move thumb
wheel repeatedly to change speed in
small steps, move and hold to change speed in large steps.
When the adaptive cruise control is
operating, the stop-start system is
automatically deactivated.
Adopting speed by the speed limit
recognition
The intelligent speed adaptation
informs the driver when a speed limit
is detected by the speed limit
recognition. The detected speed limit
can be taken over as new set speed
for the adaptive cruise control.
Using the camera at the top of the
windscreen, this system detects and
reads speed limit and end of speed
limit signs.
If the adaptive cruise control is active, the recognised speed limit will be
displayed in the Driver Information Centre and MEM illuminates if the
difference between set speed and
speed limit is more than 9 km/h.
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.
