Hill-start assist control (HAC)

Driving your vehicle / Brake system / Hill-start assist control (HAC)

A vehicle has the tendency to roll back on a steep hill when the driver begins to accelerate after a stop. The Hill-start Assist Control (HAC) prevents the vehicle from rolling back by operating the brakes automatically for about 1.5 seconds. The brakes are released when the accelerator pedal is depressed or after about 1.5 seconds.

WARNING

The HAC is activated only for about 1.5 seconds, so always depress the accelerator pedal to begin accelerating after a stop.

✽ NOTICE

• The HAC does not operate when the transaxle shift lever is in the P (Park) or N (Neutral) position.
• The HAC activates even though the ESC is off but it does not activate when the ESC has malfunctioned.
