ABS is an electronic braking system
that helps prevent a braking skid.
ABS allows the driver to steer and
brake at the same time.
Using ABS
To obtain the maximum benefit from
your ABS in an emergency situation,
do not attempt to modulate your
brake pressure and do not try to
pump your brakes. Depress your
brake pedal as hard as possible.
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 ABS is
active.
ABS does not reduce the time or dis-
tance it takes to stop the vehicle.
Always maintain a safe distance from
the vehicle in front of you.
ABS will not prevent a skid that
results from sudden changes in
direction, such as trying to take a
corner too fast or making a sudden
lane change. Always drive at a safe
speed for the road and weather con-
ditions.ABS cannot prevent a loss of stabili-
ty. Always steer moderately when
braking hard. Severe or sharp steer-
ing wheel movement can still cause
your vehicle to veer into oncoming
traffic or off the road.
On loose or uneven road surfaces,
operation of the anti-lock brake sys-
tem may result in a longer stopping
distance than for vehicles equipped
with a conventional brake system.
The ABS warning light ( ) will stay
on for several seconds after the igni-
tion switch is in the ON position.
During that time, the ABS will go
through self-diagnosis and the light
will go off if everything is normal. If
the light stays on, you may have a
problem with your ABS. Contact an
authorized HYUNDAI dealer as soon
as possible(Continued)
Drive your vehicle at reduced
speeds during the following
conditions:
Rough, gravel or snow-cov-
ered roads.
On roads where the road sur-
face is pitted or has different
surface height.
Tire chains are installed on
your vehicle.
The safety features of an ABS
or ESC equipped vehicle should
not be tested by high speed
driving or cornering. This could
endanger the safety of yourself
or others.

Information
When you jump start your vehicle
because of a drained battery, the ABS
warning light ( ) may turn on at the
same time. This happens because of
the low battery voltage. It does not
mean your ABS is malfunctioning.
Have the battery recharged before
driving the vehicle.
i
If the ABS warning light ( ) is
on and stays on, you may have
a problem with the ABS. Your
power brakes will work normal-
ly. To reduce the risk of serious
injury or death, contact your
HYUNDAI dealer as soon as
possible.When you drive on a road hav-
ing poor traction, such as an icy
road, and apply your brakes
continuously, the ABS will be
active continuously and the
ABS warning light ( ) may
illuminate. Pull your car over to
a safe place and turn the engine
off.
Restart the engine. If the ABS
warning light is off, then your
ABS system is normal.
Otherwise, you may have a
problem with your ABS system.
Contact an authorized HYUNDAI
dealer as soon as possible.

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.
WARNING

Driving your vehicle
If the Cruise Control was in use when the ESC activates, the
Cruise Control automatically disen-
gages. The Cruise Control can be
reengaged when the road condi-
tions allow. See "Cruise Control
System" later in this chapter. (if
equipped)
When moving out of the mud or driving on a slippery road, the
engine rpm (revolutions per
minute) may not increase even if
you press the accelerator pedal
deeply. This is to maintain the sta-
bility and traction of the vehicle and
does not indicate a problem.
ESC OFF condition
To cancel ESC operation :
State 1
Press the ESC OFF button shortly
(ESC OFF indicator light and mes-
sage illuminates). At this state, the
engine control function does not
operate. In other words, the traction
control function does not operate but
only the brake control function oper-
ates.
Press the ESC OFF button for more
than 3 seconds. ESC OFF indicator
light and message illuminates with
an ESC OFF warning chime. At this
state, the engine control function and
brake control function does not oper-
ate. In other words, the vehicle sta-
bility control function does not oper-
ate any more.
If the ignition switch is placed to the
LOCK/OFF position when ESC is off,
ESC remains off. Upon restarting the
engine, the ESC will automatically
turn on again.

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)
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 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.
NOTICE
i
NOTICE
Always be ready to depress the
accelerator pedal when starting
off on a incline. The HAC acti-
vates only for approximately 2
seconds.

Good Braking Practices Wet brakes can be dangerous! The
brakes may get wet if the vehicle is
driven through standing water or if it
is washed. Your vehicle will not stop
as quickly if the brakes are wet. Wet
brakes may cause the vehicle to pull
to one side.
To dry the brakes, apply the brakes
lightly until the braking action returns
to normal, taking care to keep the
vehicle under control at all times. If
the braking action does not return to
normal, stop as soon as it is safe to
do so and call an authorized
HYUNDAI dealer for assistance.
DO NOT drive with your foot resting
on the brake pedal. Even light, but
constant pedal pressure can result in
the brakes overheating, brake wear,
and possibly even brake failure.
If a tire goes flat while you are driv-
ing, apply the brakes gently and
keep the vehicle 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 location.Keep your foot firmly on the brake
pedal when the vehicle is stopped to
prevent the vehicle from rolling for-
ward.
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 ignition
switch in the OFF position.
Vehicles with the parking brake
not fully engaged are at risk for
moving inadvertently and caus-
ing injury to yourself or others.

ECO mode
When the Drive Mode isset to ECO mode, the
engine and transmission
control logic are changed
to maximize fuel efficiency.
When the ECO mode is selected by pressing the DRIVE MODE but-
ton, the ECO indicator will illumi-
nate.
If the vehicle is set to ECO mode, when the engine is turned OFF
and restarted the Drive Mode set-
ting will remain in ECO mode.
Information
Fuel efficiency depends on the driver's
driving habit and road condition. When ECO mode is activated:
The acceleration response may be
slightly reduced as the accelerator
pedal is depressed moderately.
The air conditioner performance may be limited.
The shift pattern of the automatic transmission may change.
The engine noise may get louder.
The above situations are normal
conditions when ECO mode is acti-
vated to improve fuel efficiency. Limitation of ECO mode opera-
tion:
If the following conditions occur while
ECO mode is operating, the system
operation is limited even though
there is no change in ECO indicator.
When the coolant temperature is
low:
The system will be limited until
engine performance becomes nor-
mal.
When driving up a hill: The system will be limited to gain
power when driving uphill because
engine torque is restricted.
When driving the vehicle with the automatic transmission gear shift
lever in manual shift mode:
The system will be limited accord-
ing to the shift location.
When the accelerator pedal is deeply depressed for a few seconds:
The system will be limited, judging
that the driver wants to speed up.

SPORT mode
SPORT mode managesthe driving dynamics by
automatically adjusting the
steering effort, the engine
and transmission control
logic for enhanced driver
performance.
When SPORT mode is selected by pressing the DRIVE MODE button,
the SPORT indicator will illuminate.
Whenever the engine is restarted, the Drive Mode will revert back to
COMFORT mode. If SPORT mode
is desired, re-select SPORT mode
from the DRIVE MODE button.
When SPORT mode is activated: - The engine rpm will tend to remainraised over a certain length of time
even after releasing the accelerator
- Upshifts are delayed when accel- erating
Information
In SPORT mode, the fuel efficiency
may decrease.
SMART mode
SMART mode selects the
proper driving mode
among ECO, NORMAL,
and SPORT by judging the
driver's driving habits (i.e. mild or
dynamic) from the brake pedal
depression or the steering wheel
operation.
Press the DRIVE MODE button to activate SMART mode. When
SMART mode is activated, the
indicator illuminates on the instru-
ment cluster.
The indicator illuminates in green, when the driver's driving is catego-
rized to be mild. It illuminates in
white, when the driver's driving is
categorized to be normal. It illumi-
nates in yellow, when the driver's
driving is categorized to be dynam-
ic during abrupt braking or sharp
curving.
The vehicle starts in SMART mode again, when the engine was turned
OFF in SMART mode. SMART mode automatically con-
trols the vehicle driving, such as
gear shifting patterns, engine
torque, and riding quality in accor-
dance with the driver's driving
habits.
Information
• When you mildly drive the vehiclein SMART mode, the driving mode
changes to ECO mode to improve
fuel efficiency. However, the actual
fuel efficiency may differ in accor-
dance with your driving situations
(i.e. upward/downward slope, vehi-
cle deceleration/acceleration).
• When you dynamically drive the vehicle in SMART mode by abrupt-
ly decelerating or sharply turning
the driving mode changes to SPORT
mode. However, it may adversely
affect fuel economy.
