Adaptive Cruise Control – deactivating

ACC is an optional system designed to assist the driver by maintaining a set speed or a set time interval to the vehicle ahead. It is primarily intended for use on long straight roads in steady traffic, such as on highways and other main roads.

Standby mode (temporary deactivation)

To temporarily deactivate ACC (put it in standby mode):

P3-1320-AL-USA-adaptive cruise control
Controls and display
  1. Ikon röd cirkel 1Resume previous settings.
  2. Ikon röd cirkel 2Off/On/Standby mode
  • Press P3-0720 Symbol farthållare 2 (2).

This symbol and the marking for the set speed with change colors from green to white.

The previously set speed and time interval are resumed by pressing Ikon farthållare 5 (1).

 Warning

The vehicle may accelerate quickly after Ikon farthållare 5 has been pressed if its current speed is considerably lower than the set speed.

Standby mode due to action by the driver

ACC is temporarily deactivated and put in standby mode:

  • if the brakes are applied
  • if the gear selector is moved to N
  • if the driver drives faster than the set speed for more than 1 minute.

In this happens, the driver will have to regulate the vehicle's speed.

 Note

If the accelerator pedal is only depressed for a short time, such as when passing another vehicle, ACC is deactivated temporarily and is reactivated when the pedal is released.

Automatic standby mode

ACC is linked to other systems such as the stability system. If this system is not functioning properly, ACC will switch off automatically.

In the event of automatic deactivation, an audible signal will sound and the message Cruise control Cancelled is shown in the instrument panel. The driver must then intervene and adapt the vehicle's speed to the surrounding traffic and regulate the distance to the vehicle ahead.

An automatic switch to standby mode may be caused if:

  • engine speed (rpm) is too high/low
  • The driver's door is opened
  • The driver unbuckles his/her seat belt
  • the vehicle's speed goes below 18 mph (30 km/h)
  • the wheels lose traction
  • brake temperature is high
  • the radar sensor is obstructed by, for example, wet snow or rain.

Resuming the set speed

If ACC is in standby mode, it can be reactivated by pressing the Ikon farthållare 5 button on the steering wheel keypad. The vehicle will return to the most recently set speed.

 Warning

The vehicle may accelerate quickly after Ikon farthållare 5 has been pressed if its current speed is considerably lower than the set speed.

Turning ACC off completely
