While hill-start assist control is operating, the brakes remain automati-
l
cally applied after the driver releases the brake pedal. The stop lights and
the high mounted stoplight turn on.
Hill-start assist control operates for about 2 seconds after the brake pedal

the brake pedal is further depressed, slightly reduce the pressure on the
brake pedal (do not allow the vehicle to roll backward) and then firmly
depress it again. If the system still does not operate, check that the oper-
ating conditions explained above have been met.
