Deactivation of the auto-hold brake
function
In certain situations, auto-hold will be deactivated
when the vehicle is at a standstill and ACC 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 ACC 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
•
ACC has kept the vehicle at a standstill for
more than approx. 5 minutes
•
the engine is turned off
•
the brakes overheat
