Pilot Assist auto-hold brake function

At certain speeds, Pilot Assist provides braking effect.

Stop-and-go driving

During brief stops in slow-moving traffic or att traffic lights where the vehicle is not stopped for more than 3 seconds, driving will resume automatically. If it takes more than 3 seconds for the vehicle ahead to begin moving again, Pilot Assist will go into standby mode and the auto-hold brake function will activate.

The driver will then have to reactivate Pilot Assist as follows:
    • Press the P5-1507-Symbol 5x3,5-CC rattknapp Återuppta hastighet button
    • Press the accelerator pedal
    Pilot Assist will resume following the vehicle ahead if it begins to move within approx. 6 seconds.

Note

  • Pilot Assist can keep the vehicle stationary for max. 5 minutes, after which the parking brake will be set and Pilot Assist will go into standby mode.
  • The parking brake must be released before Pilot Assist can be reactivated.

Deactivating the auto-hold brake function

In certain situations, auto-hold will be deactivated when the vehicle is at a standstill and Pilot Assist will go into standby mode.

This means that the brakes will be released and the vehicle can begin to roll.

The driver must actively apply the brakes to keep the vehicle at a standstill.

This can occur in the following situations:
  • the driver presses the brake pedal
  • the parking brake is set
  • the gear selector is moved to the P, N or R positions
  • the driver puts Pilot Assist in standby mode

Automatically setting the parking brake

In certain situations, the parking brake is set automatically to help keep the vehicle at a standstill.

This occurs if:
  • the driver unbuckles the seat belt or opens the door
  • Pilot Assist has kept the vehicle at a standstill for more than approx. 5 minutes
  • the engine is turned off
  • the brakes overheat
