Driving your vehicle

Hill-start assist control (HAC)

(if equipped)
Hill-start Assist Control is a function for
your convenience. The main intention is
to prevent the vehicle from rolling back-
wards while driving uphill on an inclined
surface. HAC holds the braking pressure
built up by the driver while stopping for 2
seconds (manual transaxle) or 0.8 sec-
onds (automatic transaxle) after releas-
ing the brake pedal.
During the pressure-hold period, the
driver has enough time to depress the
accelerator pedal to drive off.
The braking pressure is reduced as soon
as the system detects the driver's inten-
tion to drive.
WARNING
The HAC is usually activated only
for 2 seconds (manual transaxle) or
0.8 seconds (automatic transaxle).
The driver should be careful not to
roll backward causing an accident
with an object or person behind.

✽ ✽ 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.

Vehicle stability management

(VSM) (if equipped)
This system provides further enhance-
ments to vehicle stability and steering
responses when a vehicle is driving on a
slippery road or a vehicle detected
changes in coefficient of friction between
right wheels and left wheels when brak-
ing.

VSM operation

When the VSM is in operation, ESP indi-
cator light ( ) blinks.
When the vehicle stability management
is operating properly, you can feel a slight
pulsation in the vehicle. This is only the
effect of brake control and indicates noth-
ing unusual.
The VSM does not operate when:
• Driving on bank road such as gradient
or incline
• Driving rearward
• ESP OFF indicator light (
on the instrument cluster
• EPS indicator light remains on the
instrument cluster
) remains
