Driving your vehicle

Hill-start assist control (HAC)
(if equipped)

Hill start Assist Control is a convenience
function. The main intent is to prevent the
vehicle from rolling backwards while tak-
ing off uphill from a stop. HAC holds the
braking pressure built up by the driver
during stopping for 2 seconds after
releasing the brake pedal.
During the pressure-hold period, the
driver has enough time to press the
accelerator pedal to drive off.
The braking pressure is reduced as soon
as the system detects the driver's inten-
tion to drive off.

✽

✽ 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

ESP is off but it does not activate
when the ESP has malfunctioned.

WARNING

The HAC is usually activated only
for 2 seconds: If the built-up brake
hold pressure is insufficient to hold
the vehicle, the driver must quickly
activate the brake pedal to prevent
the vehicle from rolling backward.
Unexpectedly rolling backward
could cause an accident, and seri-
ous injury.
