Standby mode means that the function is selected in the driver display but not activated. Adaptive cruise control does not then regulate the speed or distance to the vehicle in front.
Standby mode on driver intervention
The adaptive cruise control is deactivated and set in standby mode if any of the following occurs:
- The foot brake is used.
- The gear selector is moved to N position.
- The driver maintains a speed higher than the stored speed for longer 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.
- 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
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 engaged in the event of one of the following:
- One of the systems that Adaptive cruise control is dependent on stops working, e.g. stability control / anti-skid (ESC).
Electronic Stability Control
- 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 radar unit is 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.
