Pilot Assistauto-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 auto-
matically. 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
button
•
Press the accelerator pedal
> Pilot Assist will resume following the vehi-
cle ahead if it begins to move within
approx. 6 seconds.
NOTE
•
Pilot Assist can keep the vehicle station-
ary 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 stand-
still.
This occurs if:
•
the driver unbuckles the seat belt or opens
the door
•
Pilot Assist has kept the vehicle at a stand-
still for more than approx. 5 minutes
•
the engine is turned off
•
the brakes overheat
