Adaptive Cruise Control ACC (cruise control)* - Temporary deactivation and standby mode

The temporary deactivation of ACC in the Volvo S80 (2nd generation, 2013–2016) is carried out through simple operation or automatically under certain conditions. This section describes how the driver can place the system in standby mode and reactivate it. Special notes concern the causes of automatic deactivation, such as loss of radar contact or high brake temperatures. Tips for safe reactivation help the driver maintain control.

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

Temporary deactivation/standby mode

To temporarily switch off the adaptive cruise control ACC (cruise control) and place it in standby mode:

• Using the steering wheel buttonpress

This symbol and the stored speed marker then change color from GREEN to WHITE.

Standby mode due to driver intervention

The adaptive cruise control is temporarily switched off and automatically placed in standby mode when:

• the service brake is applied
• the clutch pedal is depressed for longer than 1 minute7
• the selector lever is moved to the N position (automatic transmission)
• the driver maintains a speed higher than the stored speed for longer than 1 minute.

The driver must then control the speed manually.

Temporary acceleration with the accelerator pedal, e.g. when overtaking, does not affect the setting. The vehicle resumes the last stored speed as soon as the accelerator pedal is released.

7 Standby mode is not activated when disengaging the clutch or shifting to a higher or lower gear.

Automatic standby mode

The adaptive cruise control (ACC) depends on other systems, such as the electronic stability control ESC.

If one of these systems is unavailable, ACC is automatically switched off.

During automatic deactivation, a signal sounds and the message Cruise control deactivated appears in the instrument cluster.

In this case, the driver must intervene and adjust the speed and distance to the vehicle ahead manually.

Automatic deactivation may be caused by the following:

• The driver opens the door
• The driver unfastens the seat belt
• the engine speed is too low/high
• the speed has dropped below 30 km/h8
• the wheels lose contact with the road surface
• the brake temperature is high
• the radar sensor is covered, for example by wet snow or heavy rain (the radar signals are blocked).

Resuming the set speed

The adaptive cruise control ACC (cruise control) in standby mode is reactivated by pressing the steering wheel button- the speed is then set to the last stored speed.

When reactivating cruise control with the RES button, the speed may increase significantly.

The adaptive cruise control (ACC) in the Volvo S80 (2nd gen) can be temporarily deactivated and placed in standby mode at any time. This happens either automatically through driver inputs or due to certain driving situations, such as engine speed that is too high or too low.

Thanks to clear displays and audible signals, the driver is always informed about the status of the system. This allows the driver to take back control at any time when the situation requires it.

Volvo focuses here on the highest safety and ease of use for relaxed driving.
