Driving your vehicle
The Electronic Stability Control
(ESC) system is an electronic sys-
tem designed to help the driver main-
tain vehicle control under adverse
conditions. It is not a substitute for
safe driving practices. Factors includ-
ing speed, road conditions and driv-
er steering input can all affect
whether ESC will be effective in pre-
venting a loss of control. It is still your
responsibility to drive and corner at
reasonable speeds and to leave a
sufficient margin of safety.
When you apply your brakes under
conditions which may lock the
wheels, you may hear a “tik-tik’’
sound from the brakes, or feel a cor-
responding sensation in the brake
pedal. This is normal and it means
your ESC is active.✽NOTICE
A click sound may be heard in the
engine compartment when the vehi-
cle begins to move after the engine is
started. These conditions are normal
and indicate that the Electronic
Stability Control System is func-
tioning properly. WARNING
Never drive too fast according
to the road conditions or too
quickly when cornering.
Electronic Stability Control
(ESC) will not prevent acci-
dents. Excessive speed in
turns, abrupt maneuvers and
hydroplaning on wet surfaces
can still result in serious acci-
dents. Only a safe and attentive
driver can prevent accidents by
avoiding maneuvers that cause
the vehicle to lose traction.
Even with ESC installed, always
follow all the normal precau-
tions for driving - including driv-
ing at safe speeds for the condi-
tions.

ESC OFF usage
When driving
• ESC should be turned on for daily
driving whenever possible.
• To turn ESC off while driving, press
the ESC OFF button while driving
on a flat road surface.
✽NOTICE
• When operating the vehicle on a
dynamometer, ensure that the
ESC is turned off (ESC OFF light
illuminated and the buzzer beeps)
by pressing the button for 3 sec-
onds. If the ESC is left on, it may
prevent the vehicle speed from
increasing, and result in false diag-
nosis.
• Turning the ESC off does not
affect ABS or brake system opera-
tion. CAUTION
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 origi-
nal tires.
WARNING
The Electronic Stability Control
is only a driving aid; use pre-
cautions for safe driving by
slowing down on curved,
snowy, or icy roads. Drive slow-
ly and don’t attempt to acceler-
ate whenever the ESC indicator
light is blinking, or when the
road surface is slippery.
WARNING
Never press the ESC OFF but-
ton while ESC is operating (ESC
indicator light blinks).
If ESC is turned off while ESC is
operating, the vehicle may slip
out of control.
CAUTION
Even if you cancel the ESC
function by pressing the button,
the ESC function may be operat-
ed. It is normal condition for
safety driving.

Driving your vehicle
• Don't coast down hills with the
vehicle out of gear. This is extreme-
ly hazardous. Keep the car in gear
at all times, use the brakes to slow
down, then shift to a lower gear so
that engine braking will help you
maintain a safe speed.
• Don't "ride" the brake pedal.
Resting your foot on the brake
pedal while driving can be danger-
ous because it can result in the
brakes overheating and losing their
effectiveness. It also increases the
wear of the brake components.
• If a tire goes flat while you are driv-
ing, apply the brakes gently and
keep the car pointed straight
ahead while you slow down. When
you are moving slowly enough for it
to be safe to do so, pull off the road
and stop in a safe place.• If your vehicle is equipped with an
automatic transmission, don't let
your car creep forward. To avoid
creeping forward, keep your foot
firmly on the brake pedal when the
car is stopped.
• Be caution when parking on a hill.
Firmly engage the parking brake
and place the shift lever in P. If your
vehicle is facing downhill, turn the
front wheels into the curb to help
keep the vehicle from rolling. If
your vehicle is facing uphill, turn
the front wheels away from the
curb to help keep the vehicle from
rolling. If there is no curb or if it is
required by other conditions to
keep the vehicle from rolling, block
the wheels.• Under some conditions your park-
ing brake can freeze in the
engaged position. This is most like-
ly to happen when there is an
accumulation of snow or ice
around or near the rear brakes or if
the brakes are wet. If there is a risk
that the parking brake may freeze,
apply it only temporarily while you
put the shift lever in P and block
the rear wheels so the car cannot
roll. Then release the parking
brake.
• Do not hold the vehicle on the
upgrade with the accelerator
pedal. This can cause the trans-
mission to overheat. Always use
the brake pedal or parking brake.

SPORT mode
SPORT mode focuses on dynamic
driving by automatically controlling
the steering wheel, engine and
transaxle system.
• When the DRIVE MODE
button is pressed and
the SPORT mode is
selected, the SPORT
indicator will illuminate.
• If the SPORT mode is activated,
and the engine start/stop button is
turned off and on DRIVE MODE
would be changed to NORMAL
mode. To turn on the SPORT mode
press DRIVE MODE button again.
• If the system is activated:
- Deceleration from release of
accelerator pedal will result in less
rapid fall in RPM (revolutions per
minute) than in the NORMAL
mode.
- Up-shifting is delayed.
✽ NOTICE
In Sport drive mode, the fuel effi-
ciency may decrease.
✽ NOTICE
If you activate the Driving Mode
Theme on the User Settings Mode of
the LCD display (if equipped), the
SPORT and SNOW indicators will
not turn on the instrument cluster.
SNOW mode (if equipped)
Snow mode helps the driver to drive
more effectively on slippery roads
such as snowy or muddy roads.
• When the DRIVE MODE
button is pressed and

ECS (electronic controlled
suspension) malfunction
warning message
If ECS malfunction warning message
comes on while driving, ECS is not
working properly.
We recommend that the system be
checked by an authorized HYUNDAI
dealer.
✽ NOTICE
• Make sure there are no objects
under the vehicle before changing
the vehicle height.
• A click sound may be heard while
operating ECS, but these condi-
tions are normal and indicate that
ECS is functioning properly.
• Depending on the outside temper-
ature the vehicle height may be
different.
• When the vehicle is parked with
one side of the vehicle lifted or
vehicle speed is suddenly acceler-
ated/decelerated or the steering
wheel is suddenly turned, the
height may not temporarily be
adjusted. This is to protect the sys-
tem.
• When one side of the vehicle was
lifted with a jack, the height may
not temporarily be adjusted. The
ECS will operate normally when
the engine is turned on again or
when the vehicle is accelerated.
• When the vehicle is not driven for
a long period of time, vehicle
height may get low. The ECS will
operate normally when the engine
is turned on.
