Deactivating/activating Pilot Assist
Pilot Assist can be temporarily deactivated so that it is set in the standby mode and can be reactivated later.
Deactivating and setting Pilot Assist in standby mode
To temporarily switch off Pilot Assist and set it in standby mode:
Press the steering wheel button 
(2).
(2).Pilot Assist is set in standby mode - the symbol (8) in the driver display changes colour from WHITE to GREY and the stored speed in the centre of the speedometer changes from BEIGE to GREY.
...or...
Press the steering wheel button ◀ (3).
Pilot Assist is switched off and changes to the Adaptive cruise control in active mode.
Warning
- With Pilot Assist in standby mode, the driver must intervene and steer, regulating both speed and distance to the vehicle ahead.
- When Pilot Assist is in standby mode and the car comes too close to a vehicle ahead, the driver is warned of the short distance by the Distance Warning function instead.
Standby mode on driver intervention
Pilot Assist is temporarily deactivated and set in standby mode if:
- the foot brake is used.
- the gear selector is moved to N position.
- the direction indicators are used for longer than 1 minute.
- 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.
When the direction indicators are used, Pilot Assist steering assistance is temporarily disengaged. When this is no longer the case, steering assistance is automatically reactivated if the lane's side markings can still be detected.
Automatic standby mode
Pilot Assist is dependent on other systems, e.g. stability control/anti-skid ESC1. If any of these other systems stops working, Pilot Assist 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, for example:
- the driver opens the door.
- brake temperature is high.
- the driver's hands are not on the steering wheel.
- the parking brake is applied.
- engine speed is too low/high.
- the driver takes off the seatbelt.
- one or more wheels lose traction.
- 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 Pilot Assist 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 Pilot Assist no longer has a vehicle to follow.
- speed is reduced to below 30 km/h (20 mph) - only applies to cars with manual gearbox.
Reactivating Pilot Assist from the standby mode
To reactivate Pilot Assist:
Press the steering wheel button 
(1).
(1).The speed is then set to the most recently stored speed.
Warning
A significant increase in speed may follow when the speed is resumed with the steering wheel button.
