Hill-start assist control (HAC)

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

A vehicle has the tendency to slip back on a steep hill when the driver begins to accelerate after a stop. The Hill-start Assist Control (HAC) prevents the vehicle from slipping back by operating the brakes automatically for about 2 seconds. The brakes are released when the accelerator pedal is depressed or after about 2 seconds.

WARNING

The HAC is activated only for about 2 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.
