NOTE: The illustration is schematic - details may vary depending on car model.

To temporarily switch off Adaptive Cruise Control and set it in standby mode:

Press the steering wheel button (2).

Stored speed in the centre of the speedometer changes from BEIGE to GREY and the indication for time interval as well as the symbol for the target vehicle, if on, are switched off.

Warning

  • With the adaptive cruise control is in standby mode, the driver must intervene and regulate both speed and distance to the vehicle ahead.
  • When the adaptive cruise control is in standby mode and the car comes too close to a vehicle ahead, the driver is warned of the short distance by the Distance Warning function instead.

Standby mode on driver intervention

The Adaptive cruise control is temporarily deactivated and set in standby mode if:

  • the foot brake is used.
  • the gear selector is moved to N position.
  • the driver maintains a speed higher than the stored speed for longer than 1 minute.
  • the clutch pedal is depressed for approx. 1 minute - applies to cars with manual gearbox.

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.

Automatic standby mode

The adaptive cruise control is dependent on other systems, e.g. Electronic Stability Control ESCElectronic Stability Control. If any of the other systems stops working, the adaptive cruise control is deactivated automatically.

Warning

With automatic standby mode, the driver is warned via an acoustic signal and a message on the driver display.

  • The driver must then regulate the car's speed, apply the brakes as needed and maintain a safe distance to other vehicles.

Automatic standby mode may occur if:

  • the speed is below 5 km/h (3 mph) and ACC is uncertain whether the vehicle ahead is a stationary vehicle or an object, such as a speed bump.
  • the speed is below 5 km/h (3 mph) and the vehicle ahead turns off so that ACC no longer has a vehicle to follow.
  • speed is reduced to below 30 km/h (20 mph) - only applies to cars with manual gearbox.
  • the driver opens the door.
  • the driver takes off the seatbelt.
  • engine speed is too low/high.
  • one or more wheels lose traction.
  • brake temperature is high.
  • the parking brake is applied.
  • the camera and radar unit is covered by e.g. snow or heavy rainfall (camera lens/radio waves are blocked).

Warning

A significant increase in speed may follow when the speed is resumed with the steering wheel button.
