■Brake control is operating
■The vehicle is stopped by system
operation
*: If the accelerator pedal is not depressed, “Press Brake Pedal” will be displayed.
■System operation
When the vehicle is stopped by system
operation, the Parking Support Brake func-
tion (for static objects) stops and the PKSB
OFF indicator illuminates.
■System recovery
When the Parking Support Brake function
(for static objects) is stopped by system
operation and you would like to resume
operation, either turn the Parking Support
Brake function (for static objects) ON again
( P.253), or turn the power switch off and
then back on. Furthermore, when the vehi-
cle moves with a static object no longer in
the traveling direction of the vehicle, or
when the traveling direction of the vehicle
changes (such as when switching from
moving forward to backing up, and vice
versa), system operation automatically
resumes.
■Clearance sonar buzzer
Regardless of whether the clearance sonar
is on or off, if the Parking Support Brake
function (for static ob jects) is not stopped
( P.253), when the front or rear sensors
detect a static object and brake control is
performed, the clearance sonar buzzer also
sounds and a notification of the approxi-
mate distance to the static object is pro-
vided.
■In the unlikely event that the Parking
Support Brake function (for static
objects) mistakenly operates at a cross-
ing or elsewhere
Even in the unlikely event that the Parking
Support Brake function (for static objects)
mistakenly operates at a crossing or else-
where, brake control is canceled after
approximately 2 seconds, allowing you to
proceed forward and leave the area. Fur-
thermore, brake control is also canceled
when the brake pedal is depressed.
Depressing the accelerator pedal again
allows you to proceed forward and leave
the area.
