Hill-start assist control (HAC) (if

equipped)
Hill start Assist Control is a comfort
function. The main intend is to pre -
vent the vehicle from rolling back -
wards whilst driving off uphill on an
inclined surface. HAC holds the
braking pressure builtup by driver
during stopping procedure for 2
seconds after releasing 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 intention to drive off.
WARNING
The HAC is usually activated only for
2 seconds. The driver should be
careful from the rolling backward
causing the accident with behind
objects or human, when the driver
may feel the unintended rolling
backward whilst driving off on hill
due to insufficient brake hold pres -
sure built-up by driver during stop -
ping procedure.

the transmission shift lever is in
the P (Park) or N (Neutral) posi -
tion.
The HAC activates even though
the ESC is off but it does not acti -
vate when the ESC has malfunc -
tioned.
