In the unlikely event that the Parking Support Brake function mistakenly
operates at a crossing or elsewhere
Even in the unlikely event that the Parking Support Brake function mistakenly
operates at a crossing or elsewhere, brake control is canceled after approxi-
mately 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.
