Deactivation of 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 Pilot Assist keeps the vehicle at a
standstill with the brakes and:
•
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

Pilot Assist limitations
Pilot Assist functionality may be limited in certain
situations.
Pilot Assist is designed to help the driver in a
number of situations. However, the driver always
has the primary responsibility for maintaining a
safe distance to other vehicles and for keeping
the vehicle in its proper traffic lane.
