Hill-Start Assist Control (HAC)

(if equipped)
A vehicle has the tendency to slide
backwards on a steep slope, before
depressing the accelerator after a
stop. The HAC prevents the vehicle
from sliding backwards by automati-
cally operating the brake systems for
about 2 seconds. The brake systems
are automatically released, when the
accelerator pedal is depressed.
WARNING
The HAC is activated only for
about 2 seconds, so always
depress the accelerator pedal
to begin driving upwards after a
stop.
i
Information
• The HAC does not operate when the
shift lever is in P (Park) or N (Neutral).
• The HAC activates even when the
ESC (Electronic Stability Control) is
off. However, it does not activate,
when the ESC does not normally
operate.

Emergency Stop Signal (ESS)

(if equipped)
The Emergency Stop Signal system
alerts the driver behind by blinking
the stop lights, while sharply and
severely braking.
The system is activated when:
• The vehicle suddenly stops. (The
deceleration power exceeds 7 m/s
and the driving speed exceeds 55
km/h (34 mph).)
• The ABS is activated.
The hazard warning flasher automat-
ically turns ON after blinking the stop
lights, when the driving speeds is
decelerated under 40 km/h (25 mph),
when the ABS is deactivated, and
when the sudden braking situation is
over.
The hazard warning flasher turns
OFF, when the driving speed exceeds
10 km/h (6 mph) after a complete
stop. The hazard warning flasher
turns OFF, when the vehicle drives at
a low speed for a certain period of
time. The driver can manually turn
OFF the hazard warning flasher by
pressing the button.
