■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-

brake control can be canceled by
depressing the brake pedal or wait- ing for approximate
ly 2 seconds for
it to automatically be canceled.
Then, the vehicle can be operated
by depressing the accelerator pedal.

To re-enable the Parking Support
Brake when it is disabled due to
operation of the Parking Support
Brake, either enable the system
again ( P.282), or turn the engine
switch to OFF and then back to ON.
Additionally, if the object becomes
no longer in the traveling direction of
the vehicle or if the traveling direc-
tion of the vehicle changes (such as
changing from moving forward to
backing up, or from backing up to
moving forward), t he system will be
re-enabled automatically.
