Adjusting the set speed for driver support
It is possible to adjust set speeds for the cruise control, Adaptive Cruise Control* and Pilot Assist* functions.

: Increases the set speed
: Reduces the set speed
Set speed
- Change a set speed by pressing the
(1) or
(2) buttons briefly or by pressing and holding them:- Short press: Each press changes the speed in +/- 5 km/h increments.
- Press and hold: Release the button when the set speed indicator (3) has moved to the desired speed.
- The most recently set speed will be stored.
Pressing the accelerator pedal
If speed is increased by depressing the accelerator pedal while pressing the
(1) button on the steering wheel, the vehicle's speed when the button is pressed will be stored as the set speed.
Temporarily increasing speed using the accelerator pedal, for example when passing another vehicle, will not affect the setting. The vehicle will return to the set speed when the accelerator pedal is released.
Possible speed
Automatic Transmission
The driver support functions can follow another vehicle at speeds from a standstill up to 200 km/h.
Pilot Assist can provide steering assistance from near-stationary speeds up to 140 km/h.
The lowest speed that can be set is 30 km/h. When following another vehicle, ACC can monitor that vehicle's speed and slow your own vehicle down to a standstill, but it is not possible to set speeds lower than 30 km/h.
