A buzzer will sound once to indicate the system is activated.

The slip indicator will also start flashing.

Hill-start assist control can be operated when

The parking brake is not applied.

The accelerator pedal is not depressed.

Hill-start assist control

While hill-start assist control is operating, the brakes remain automatically 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 is
released.

If the slip indicator does not flash and the buzzer does not sound when 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 if the operating conditions explained above have been met.

CAUTION:
Hill-start assist control Do not overly rely on hill-start assist control. Hill-start assist control may not operate
effectively on extremely steep inclines or roads covered in ice.

Unlike the parking brake, hill-start assist control is not intended to hold the vehicle
stationary for an extended period of time. Do not attempt to use hill-start assist control to hold the vehicle on an incline for an extended period of time, as
doing so may lead to an accident.
