Standby mode for adaptive cruise control*1
The adaptive cruise control (ACC2) can be deactivated and set in standby mode. This can take place automatically or due to intervention by the driver.
Standby mode means that the function is selected in the centre display but not activated. The symbol in the driver display is extinguished and the adaptive cruise control does not then regulate the speed or distance to vehicles ahead.
Standby mode on driver intervention
Adaptive cruise control is deactivated and set to standby mode if any of the following occur:
- The foot brake is used.
- The gear selector is moved to the N position.
- The driver maintains a speed higher than the stored speed for more than 1 minute.
A temporary increase in speed with the accelerator pedal, e.g. during overtaking, does not affect the setting - the car returns to the last stored speed when the accelerator pedal is released.
Warning
- With the adaptive cruise control is in standby mode, the driver must intervene and regulate both speed and distance to the vehicle ahead.
- When the adaptive cruise control is in standby mode and the car comes too close to a vehicle ahead, the driver may be warned of the short distance by the Distance Warning* function instead.
Automatic standby mode
Warning
With automatic standby mode, the driver is warned via an acoustic signal and a message in the driver display.
- The driver must then regulate the car's speed, apply the brakes as needed and maintain a safe distance to other vehicles.
Automatic standby mode may be enabled if any of the following occur:
- Any of the systems on which adaptive cruise control is dependent stops working, e.g. stability control/anti-skid (ESC3).
- The driver opens the door.
- The driver takes off the seatbelt.
- The engine speed is too low/high.
- One or more wheels lose traction.
- The brake temperature is high.
- The parking brake is applied.
- The camera and/or radar units are covered by e.g. snow or heavy rainfall (camera lens/radio waves are blocked).
- The speed is below 5 km/h (3 mph) and ACC is uncertain whether the vehicle ahead is a stationary vehicle or an object, such as a speed bump.
- The speed is below 5 km/h (3 mph) and the vehicle ahead turns off so that ACC no longer has a vehicle to follow.
