Function buttons and symbols
To temporarily deactivate and put Adaptive Cruise Control in standby mode:
Press the P5-1507-Symbol 5x3,5-CC rattknapp Centrum-V button (2).
The P5-1507- Symbol(i txt) farthållare 2 symbol in the instrument panel will change colors from WHITE to GRAY and the set speed in the center of the speedometer will change from BEIGE to GRAY.

 Warning

When ACC is in standby mode, the driver has to control the vehicle's speed and distance to a vehicle ahead.

When ACC is in standby mode, the driver will be alerted if the distance to the vehicle ahead is too short by the Distance Alert function. See the article "Distance Alert" for additional information.

Standby mode due to action by the driver

ACC is temporarily deactivated and put in standby mode if:
  • the brakes are applied
  • The gear selector is moved to N
  • the vehicle is driven faster than the set speed for more than 1 minute.

In these cases, the driver will have to regulate the vehicle's speed.

A temporary increase in speed, such as when passing another vehicle, does not affect the ACC set speed. The vehicle will return to the set speed when the accelerator pedal is released.

Automatic standby mode

ACC interacts with other systems, such as Electronic Stability Control. If any of these other systems are not functioning properly, ACC will turn off automatically.

 Warning

If this happens, the driver will be alerted by an audible signal and a message in the instrument panel. The driver will have to adapt the vehicle's speed, apply the brakes when necessary and keep a safe distance to the vehicle ahead.
ACC switches automatically to standby mode if:
  • the vehicle's speed goes below approx. 3 mph (5 km/h) and ACC cannot determine if the vehicle ahead is stationary or is an object such as a speed bump, etc
  • the vehicle's speed goes below approx. 3 mph (5 km/h) and the vehicle ahead changes lanes or turns so that ACC no longer has a target vehicle to follow
  • the driver opens the door
  • the driver unbuckles the seat belt
  • the engine speed (rpm) is too high/low
  • the wheels lose traction
  • the brake temperature is too high
  • the parking brake is applied
  • the stability system's ESC Sport Mode is activated
  • the Off Road drive mode is selected
  • The radar sensor is covered by e.g., wet snow or if heavy rain interferes with radar waves
