Adaptive cruise control* - symbols and messages

Updated 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.

Sometimes the adaptive cruise control may display a symbol and/or text message. Here are some examples - follow the recommendation given if appropriate:

Symbol

Message

Specification

The symbol is GREEN

The car maintains the stored speed.

The symbol is WHITE

Adaptive cruise control is set to standby mode.

Standard cruise control is selected manually.

Set ESC to Normal to enable Cruise

The adaptive cruise control cannot be activated until the Stability system (ESC) has been set in Normal mode.

Adaptive cruise control cancelled

The adaptive cruise control has been deactivated - the driver has to regulate the speed himself.

Adaptive cruise control unavailable

The adaptive cruise control cannot be activated.

This could be due to:

  • brake temperature is high
  • the radar sensor is blocked by e.g. wet snow or rain.

Radar blocked See manual

The adaptive cruise control is temporarily disengaged.

  • The radar sensor is blocked and cannot detect other vehicles. For example, in the event of heavy rain or if slush has collected in front of the radar sensor.

The driver can then choose to switch to normal Cruise control (CC) - a text message provides information on appropriate alternatives.

Adaptive cruise control Service required

The adaptive cruise control is disengaged.

  • Contact a workshop - an authorised Volvo workshop is recommended.

Press brake to hold vehicle + acoustic alarmOnly with Queue Assist.

The car is stationary and the cruise control will release the foot brake to allow the parking brake to take over and hold the car, but a fault in the parking brake means the car will shortly begin to roll.

  • The driver must brake himself/herself. The message remains and the alarm sounds until the driver depresses the brake pedal or uses the accelerator pedal.

Below 30 km/h Lead vehicle required Only with Queue Assist.

Shown in the event of attempts to activate the adaptive cruise control at speeds below 30 km/h (20 mph) without a vehicle in front within the activation distance.
