Hill-Start Assist Control (Hac); Emergency Stop Signal (Ess) - Hyundai Santa Fe Owner's Manual

Trailer stability assist system contin-
uously analyzes the vehicle and trail-
er instability. When the Trailer stabili-
ty assist system detects some sway,
the brakes are applied automatically
to stabilize the vehicle on the front
wheel. However, if it is not enough to
stabilize, the brakes are applied on
all wheels automatically and engine
power is properly reduced. When the
vehicle is stable from swaying, trailer
stability assist system does not oper-
ate.

Hill-Start Assist Control (HAC)

(if equipped)
The Hill-Start Assist Control (HAC)
helps prevent the vehicle from rolling
backwards when starting a vehicle
from a stop on a hill. The system
operates the brakes automatically for
approximately 2 seconds and releas-
es the brake after 2 seconds or when
the accelerator pedal is depressed.
WARNING
Always be ready to depress the
accelerator pedal when starting
off on a incline. The HAC acti-
vates only for approximately 2
seconds.
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 operate nor-
mally.

Emergency Stop Signal (ESS)

(if equipped)
The Emergency Stop Signal system
