Deactivating/activating the 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

NOTE: The illustration is schematic - details may vary depending on car model.
To temporarily switch off Pilot Assist and set it in standby mode:
Press the steering wheel button P5-1507-Symbol 5x3,5-CC rattknapp Centrum-V (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 ◀ (3).
Pilot Assist is switched off and changes to the adaptive cruise control in active mode.

In standby mode, the driver is no longer given any driver steering recommendations and must control both speed and distance him/herself.

When Pilot Assist is in standby mode and the car drives too close to a vehicle ahead, the driver is warned about the short distance by the Distance Warning function instead (see reference to the heading "Distance Warning" at the end of this section).

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 ESC. If any of these other systems stops working, Pilot Assist is switched off automatically.

In the event of automatic deactivation a signal will sound and a message is shown in the driver display. The driver must then intervene and adapt the speed and distance to the vehicle ahead.

Automatic deactivation may occur if:
  • 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.
  • the driver's hands are not on the steering wheel
  • the driver opens the door
  • the driver takes off the seatbelt
  • engine speed is too low/high
  • 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 Pilot Assist from the standby mode
