Setting the stored speed for cruise control functions

It is possible to set stored speed for the speed limiter, cruise control, adaptive cruise control* and Pilot Assist* functions.

P5+6-1746 - Adaptive Cruise Control, managing speed
: Increases the stored speed
: Reduces stored speed
Stored speed

Change a set speed with short presses on the steering wheel buttons (1) or (2) or by pressing and holding them.

  • Short presses: Each press changes the speed in increments of +/- 5 km/h (+/- 5 mph).
  • Press and hold: Release the button when the speed indicator (3) has moved to the desired speed.

The speed set after the last button press is stored in the memory.

Effect of the accelerator pedal

If the driver increases the car's speed using the accelerator pedal before pressing the steering wheel button (1), the speed stored will be the car's speed when the button is depressed, provided the driver's foot is on the accelerator pedal at the moment when the button is depressed.

A temporary increase in speed with the accelerator pedal, e.g. during overtaking, does not affect the setting - the car returns to the last stored speed when the accelerator pedal is released.

Possible speed

Automatic gearbox

The driver support functions can follow another vehicle at speeds from 0 km/h up to 180 km/h (112 mph).

Pilot Assist can give steering assistance from almost stationary up to 140 km/h (87 mph).

Note that the lowest programmable speed is 30 km/h (20 mph) – even though it is capable of following another vehicle down to 0 km/h, a speed lower than 30 km/h (20 mph) cannot be selected/stored.
