Adaptive cruise control

Adaptive cruise control* - temporary deactivation, and standby mode

업데이트됨 7/23/2018

The adaptive cruise control(ACC – Adaptive Cruise Control) helps the driver to maintain an even speed combined with a pre-selected time interval to the vehicle ahead.

The adaptive cruise control can be temporarily deactivated and set in standby mode.

Temporary deactivation/standby mode - with speed limiter

To temporarily disengage adaptive cruise control and set it in standby mode:

  • Press the steering wheel button
This symbol and stored speed marking then changes colour from GREEN to WHITE.

Temporary deactivation/standby mode - without speed limiter

To temporarily disengage adaptive cruise control and set it in standby mode:

  • Press the steering wheel button

Standby mode due to driver intervention

The adaptive cruise control is temporarily disengaged and set automatically in standby mode if:

  • the foot brake is used
  • the clutch pedal is depressed for longer than 1 minute

    Disengaging and selecting a higher or lower gear does not involve standby mode.

  • the gear selector is moved to N position (automatic gearbox)
  • the driver maintains speed higher than the stored speed for longer than 1 minute.

The driver must then regulate the speed.

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.

For more information, see the sections Managing speed and Overtaking another vehicle.

Automatic standby mode

The adaptive cruise control is dependent on other systems, e.g. Stability system ESC. If any of these systems stops working, the adaptive cruise control is deactivated automatically.

In the event of automatic deactivation a signal will sound and the message Adaptive cruise control cancelled is shown in the combined instrument panel. The driver must then intervene and adapt the speed and distance to the vehicle ahead.

An automatic deactivation can be due to:

  • the driver opens the door
  • the driver takes off his seatbelt
  • engine speed is too low/high
  • speed has fallen below 30 km/h

    Does not apply to a car with Queue Assist - it can go all the way down to 0 km/h.

    (20 mph)
  • wheels lose traction
  • brake temperature is high
  • the radar sensor is covered e.g. by wet snow or heavy rain (radar waves blocked).

For more information on symbols, messages and their meaning, see section Symbols and messages in the display.

Resume set speed

Adaptive cruise control in standby mode is reactivated with one press on the steering wheel button - the speed is then set to the last stored speed.

참고

A marked speed increase may occur once the speed has been resumed by selecting .
