Descent control system
The descent control system allows
the vehicle to travel at a low speed
without depressing the brake pedal.
The vehicle will automatically
decelerate to a low speed and remain at that speed when the system is
activated. Some noise or vibration
from the brake system may be
apparent when the system is active.
Driving and operating167Caution

Selective ride controlCaution
The vehicle is designed to drive
principally on-road, but it also
enables driving off-road
occasionally.
However, do not drive on terrain
where the vehicle could be
damaged due to obstacles, such
as rocks among others and on
terrain with steep inclines and
poor grip.
Do not cross waters.Caution
When driving off-road, sudden
motion and manoeuvres can
cause a collision or losing control.
Selective ride control is designed to
optimise traction in low-grip
conditions (snow, mud and sand).
It adapts to the terrain by acting on the
front wheels, in doing so this saves
the weight normally associated with a more conventional four wheel drive
system.Selective ride control allows to
choose between five driving modes:
● ESC off mode 9
● standard mode 2
● snow mode 3
● mud mode 4
● sand mode 1
The several modes can be activated
by turning the control.
A LED illuminates and a status
message appears in the Driver
Information Centre to confirm the
chosen mode.
172Driving and operatingPress 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

automatically:
● The brake pedal is depressed.
● The clutch 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) / the
first or second gear (manual
transmission).
Resume stored speed
Press thumb wheel to RES/+ at a
speed above 40 km/h. The stored
speed will be obtained.
Switching off the system
Press m, the cruise control mode is
deselected and the cruise control
indication extinguishes in the Driver
Information Centre.
Pressing ß 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 cruise control 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 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
Centre.
Driving and operating175the windscreen 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 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.
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.
Switching on the system
Press C, the symbol C is indicated in
the Driver Information Centre. The
system is still not active.
Driving and operating177Resuming stored speedMove 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 3 118.
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
opened and the driver's seat belt is
unfastened, then the electric parking
brake is applied automatically to hold the vehicle. Control indicator m will
illuminate. To release electric parking
brake, press the accelerator pedal.
Electric parking brake 3 162.9 Warning
When the system is deactivated or
cancelled, the vehicle will no
longer be held at a stop and can
178Driving and operatingstart moving. Be always 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 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 to maintain the following distance
selected by the driver.
The following distance can be set to
close (1 bar), normal (2 bars) or far
(3 bars).
If the engine is running and the
adaptive cruise control is enabled
(grey), you can modify the following
distance setting:
Press Ö, the current setting is shown
in the Driver Information Centre.
Press Ö again to change the following
distance: The new setting is
displayed in the Driver Information
Centre.
The selected following distance is
indicated by full bars in the adaptive
cruise control page.9 Warning
The driver accepts full
responsibility for the appropriate
following distance based on traffic, weather and visibility conditions.
Following distance must be
adjusted or the system switched
off when required by the prevailing
conditions.
Detecting the vehicle ahead
If the system detects a vehicle in the
driving path, the adaptive cruise
control symbol displayed in the Driver
Information Centre changes: - is
changed to w.
Deactivation of the functionality
Press Ñ, the adaptive cruise control
is in pause mode and a message is
displayed. The vehicle is driven
without adaptive cruise control.
The adaptive cruise control is
deactivated, but not disabled. The
last stored set speed remains in
memory for later usage.
The 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.
Driving and operating179● The electric parking brake isapplied.
● 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.
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 system when the spare wheel is in use.
System limits9 Warning
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.
● Do not use the adaptive cruise control when towing a trailer.
● Do not use the adaptive cruise control on roads with an incline ofmore than 10%.
Bends
The adaptive cruise control calculates
a predicted path based on the
centrifugal force. This predicted path
considers the current bend
characteristic, but cannot consider a
future bend change. The system may lose the current vehicle ahead or
consider a vehicle which is not in the
actual lane. This can happen when
entering or exiting a bend or if the
bend gets stronger or weaker. If it no
