Electronic Stability Control
(ESC)
The Electronic Stability Control
(ESC) system helps to stabilize the
vehicle during cornering maneuvers.
ESC checks where you are steering
and where the vehicle is actually
going. ESC applies braking pressure
to any one of the vehicle's brakes
and intervenes in the engine man-
agement system to assist the driver
with keeping the vehicle on the
intended path. It is not a substitute
for safe driving practices. Always
adjust your speed and driving to the
road conditions.
ESC operation
ESC ON condition
When the ignition switch is in the ON
position, the ESC and the ESC OFF
indicator lights illuminate for approxi-
mately three seconds and goes off,
then the ESC is turned on.
When operating
When the ESC is in opera-
tion, the ESC indicator light
blinks:
When you apply your brakes under conditions which may lock the
wheels, you may hear sounds from
the brakes, or feel a corresponding
sensation in the brake pedal. This
is normal and it means your ESC is
active.
When the ESC activates, the engine may not respond to the
accelerator as it does under rou-
tine conditions.
Never drive too fast for the road
conditions or too quickly when
cornering. The ESC system will
not prevent accidents.
Excessive speed in turns, abrupt
maneuvers, and hydroplaning
on wet surfaces can result in
severe accidents.

Indicator lights
When the ignition switch is placed to
the ON position, the ESC indicator
light illuminates, then goes off if the
ESC system is operating 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 your vehicle
checked by an authorized HYUNDAI
dealer as soon as possible.The ESC OFF indicator light comes
on when the ESC is turned off.
Driving with varying tire or wheel
sizes may cause the ESC system
to malfunction. When replacing
tires, make sure they are the same
size as your original tires for this
vehicle.
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.
NOTICE
When the ESC is blinking, this
indicates the ESC is active:
Drive slowly and NEVER
attempt to accelerate. NEVER
turn the ESC off while the ESC
indicator light is blinking or you
may lose control of the vehicle
resulting in an accident.

Driving your vehicle
To prevent damage to the trans-
mission:
Do not allow wheel(s) of one axle to spin excessively while
the ESC, ABS, and brake warn-
ing 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, ensure the ESC is
turned off (ESC OFF light illumi-
nated).
Information
Turning the ESC off does not affect
ABS or standard brake system opera-
tion.
Hill-Start Assist Control (HAC)
The Hill-Start Assist Control (HAC)
prevents 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 when the accelerator
pedal is depressed or after 2 sec-
onds. 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.

Maintenance
Owner Maintenance Schedule
When you stop for fuel:
Check the engine oil level.
Check coolant level in the enginecoolant reservoir.
Check the windshield washer fluid level.
Check for low or under-inflated tires.
While operating your vehicle:
Note any changes in the sound ofthe exhaust or any smell of
exhaust fumes in the vehicle.
Check for vibrations in the steering wheel. Notice if there is any
increased steering effort or loose-
ness in the steering wheel, or
change in its straight-ahead posi-
tion.
Notice if your vehicle constantly turns slightly or "pulls" to one side
when traveling on smooth, level
road.
When stopping, listen and check for unusual sounds, pulling to one
side, increased brake pedal travel
or "hard-to-push" brake pedal.
If any slipping or changes in the operation of your transmission
occurs, check the transmission
fluid level.
Check the automatic transmission /ecoshift dual clutch transmission
P (Park) function.
Check the parking brake.
Check for fluid leaks under your vehicle (water dripping from the air
conditioning system during or after
use is normal).
At least monthly:
Check coolant level in the enginecoolant reservoir.
Check the operation of all exterior lights, including the stoplights, turn
signals and hazard warning flashers.
Check the inflation pressures of all tires including the spare for tires
that are worn, show uneven wear,
or are damaged.
Check for loose wheel lug nuts.
Be careful when checking your
engine coolant level when the
engine is hot. This may result in
coolant being blown out of the
opening and cause serious
burns and other injuries.
