Adaptive Cruise Control – deactivating

Updated 2023-06-08

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

Ikon röd cirkel 1 — Controls and display

Press (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

From standby mode, press (2) once.
From active mode, press (2) twice.

The set speed and time interval are then cleared from the system's memory and cannot be resumed by pressing (1) Ikon farthållare 5 .
