Driving your vehicle

Press the ESC OFF button continu-
ously for more than 3 seconds. The
ESC OFF indicator light and mes-
sage illuminates and a warning
chime sounds. In this state, both the
traction control function of ESC
(engine management) and the brake
control function of ESC (braking
management) are disabled.
If the Engine Start/Stop button is
placed to the OFF position when
ESC is off, ESC remains off. Upon
restarting the engine, the ESC will
automatically turn on again.
Indicator lights
When the Engine Start/Stop button
is pressed to the ON position, the
ESC indicator light illuminates, then
goes off if the ESC system is operat-
ing normally.
The ESC indicator light blinks when-
ever the ESC is operating.
If ESC indicator light stays on, your
vehicle may have a malfunction with
the ESC system. When this warning
light illuminates, have the vehicle
checked by an authorized HYUNDAI
dealer as soon as possible. The ESC OFF indicator light comes
on when the ESC is turned off with
the button.
Driving with wheels and tires with
different sizes may cause the ESC
system to malfunction. Before
replacing tires, make sure all four
tires and wheels are the same
size. Never drive the vehicle with
different sized tires and wheels
installed.

ESC OFF usage
When Driving
The ESC OFF mode should only be
used briefly to help free the vehicle if
stuck in snow or mud by temporarily
stopping operation of the ESC to
maintain wheel torque.
To turn ESC off while driving, press
the ESC OFF button while driving on
a flat road surface.To prevent damage to the trans-
mission:
Do not allow wheel(s) of one
axle to spin excessively while
the ESC, ABS, and parking brake
warning ( , red color) lights
are displayed. The repairs would
not be covered by the vehicle
warranty. Reduce engine power
and do not spin the wheel(s)
excessively while these lights
are displayed.
When operating the vehicle on a dynamometer, make sure the
ESC is turned off (ESC OFF light
illuminated).
Information
Turning the ESC off does not affect
ABS or standard brake system opera-
tion.
Vehicle Stability Management
(VSM)
The Vehicle Stability Management
(VSM) is a function of the Electronic
Stability Control (ESC) system. It
helps ensure the vehicle stays stable
when accelerating or braking sud-
denly on wet, slippery and rough
roads where traction over the four
tires can suddenly become uneven.
i
NOTICE
Take the following precautions
when using the Vehicle Stability
Management (VSM):
ALWAYS check the speed and
the distance to the vehicle
ahead. The VSM is not a sub-
stitute for safe driving prac-
tices.
Never drive too fast for the
road conditions. The VSM sys-
tem will not prevent acci-
dents. Excessive speed in bad
weather, slippery and uneven
roads can result in severe
accidents.

Hill-Start Assist Control (HAC)
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. The HAC does not operate when
the shift lever is in P (Park) or N
(Neutral).
The HAC activates even though the ESC (Electronic Stability
Control) is off but does not acti-
vate when the ESC has malfunc-
tioned.
Good braking practices NOTICE
Always be ready to depress the
accelerator pedal when starting
off on a incline. The HAC activates
only for approximately 2 seconds.
WARNING
Whenever leaving the vehicle or
parking, always come to a com-
plete stop and continue to
depress the brake pedal. Move
the shift lever into the P (Park)
position, then apply the parking
brake, and place the Engine
Start/Stop button in the OFF
position.
Vehicles parked with the park-
ing brake not applied or not
fully engaged may roll inadver-
tently and may cause injury to
the driver and others. ALWAYS
apply the parking brake before
exiting the vehicle.
