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
resume.Cruise control is deactivated
automatically:
● 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) / 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 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
