■If the Parking Support Brake
has operated
If the vehicle is stopped due to oper-
ation of the Parki ng Support Brake,
the Parking Suppor t Brake will be
disabled and the PKSB OFF indica-
tor will illuminate. If the Parking Sup-
port Brake operates unnecessarily,
brake control can be canceled by
depressing the brake pedal or wait-
ing for approximately 2 seconds for
it to automatically be canceled. Then, the vehicle can be operated
by depressing the accelerator pedal.
■Re-enabling the Parking Sup-
port Brake

■The Parking Support Brake
function (static object) will
operate when
The function will operate when the
PKSB OFF indicator is not illumi-
nated or flashing ( P.75, 76) and all
of the following conditions are met:
●Engine output restriction control
• The Parking Support Brake is
enabled.
• The vehicle speed is approxi- mately 9 mph (15 km/h) or less.
• There is a static object in the trav- eling direction o f the vehicle and
approximately 6 to 13 ft. (2 to 4 m)
away.
• The Parking Support Brake deter- mines that a stronger-than-nor-
mal brake operation is necessary
to avoid a collision.
●Brake control
• Engine output restri ction control is
operating.
• The Parking Support Brake deter- mines that an immediate brake
operation is necessary to avoid a
collision.
■The Parking Support Brake
function (static objects) will
stop operating when
The function will st op operating if
any of the following conditions are
met:
●Engine output restriction control
• The Parking Support Brake is dis- abled.
• The system determines that the collision has become avoidable
with normal brake operation.
• The static object is no longer
approximately 6 to 13 ft. (2 to 4 m)
away from the vehicle or in the
traveling direction of the vehicle.
●Brake control
• The Parking Support Brake is dis-
abled.
• Approximately 2 seconds have elapsed since the vehicle was
stopped by brake control.
• The brake pedal is depressed after the vehicle is stopped by
brake control.
• The static object is no longer approximately 6 to 13 ft. (2 to 4 m)
away from the vehicle or in the
traveling direction of the vehicle.
■Detection range of the Parking
Support Brake function (static
objects)
The detection range of the Parking
Support Brake function (static
objects) differs from the detection
range of the intuitive parking assist.
( P.280) Therefore, even if the intu-
itive parking assist detects an object
and provides a warning, the Parking
Support Brake function (static
objects) may not start operating.
