Deactivating/reactivating adaptive cruise control*
The Adaptive cruise control (ACC[1]) can be temporarily deactivated so that it is set in the standby mode and can later be reactivated.
Deactivate Adaptive Cruise Control and set it in standby mode
To temporarily switch off Adaptive Cruise Control and set it in standby mode:
- Press the steering wheel button
(2).The
symbol on the driver display changes colour from WHITE to GREY and the stored speed in the centre of the speedometer changes from BEIGE to GREY.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.
Standby mode on driver intervention
The Adaptive cruise control is temporarily deactivated and set in standby mode if:
- 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.
- the clutch pedal is depressed for approx. 1 minute - applies to cars with manual gearbox.
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.
Automatic standby mode
Adaptive cruise control is dependent on other systems, e.g. stability control/anti-skid ESC[2]. If any of these other systems stops working, adaptive cruise control is switched off automatically.
Warning
With automatic standby mode, the driver is warned via an acoustic signal and a message on 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 occur if:
- 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.
- speed is reduced to below 30 km/h (20 mph) - only applies to cars with manual gearbox.
- the driver opens the door.
- the driver takes off the seatbelt.
- engine speed is too low/high.
- one or more wheels lose traction.
- 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).
Reactivating adaptive cruise control from standby mode
To reactivate ACC from standby mode:
- Press the steering wheel button
(1).The speed is then set to the most recently stored speed.
A significant increase in speed may follow when the speed is resumed with theWarning
