Anti-lock brake system (ABS)
(if equipped)
The ABS continuously senses the speed
of the wheels. If the wheels are going to
lock, the ABS system repeatedly modu-
lates the hydraulic brake pressure to the
wheels.
When you apply your brakes under con-
ditions which may lock the wheels, you
may hear a “tik-tik’’ sound from the
brakes, or feel a corresponding sensa-
tion in the brake pedal. This is normal
and it means your ABS is active.
In order to obtain the maximum benefit
from your ABS in an emergency situa-
tion, do not attempt to modulate your
brake pressure and do not try to pump
your brakes. Depress your brake pedal
as hard as possible or as hard as the sit-
uation allows the ABS to control the force
being delivered to the brakes.
WARNING
ABS (or ESP) will not prevent acci-
dents due to improper or danger-
ous driving maneuvers. Even
though vehicle control is improved
during emergency braking, always
maintain a safe distance between
you and objects ahead. Vehicle
speeds should always be reduced
during extreme road conditions.
The braking distance for vehicles
equipped with an anti-lock braking
system (Electronic Stability
Program System) may be longer
than for those without it in the fol-
lowing road conditions.
During these conditions the vehicle
should be driven at reduced
speeds:
• Rough, gravel or snow-covered
roads.
• With tire chains installed.
• On roads where the road surface
is pitted or has different surface
height.

(Continued)
The safety features of an ABS (or
ESP) equipped vehicle should not
be tested by high speed driving or
cornering. This could endanger the
safety of yourself or others.

Driving your vehicle
✽NOTICE
A click sound may be heard in the
engine compartment when the vehicle
begins to move after the engine is start-
ed. These conditions are normal and
indicate that the anti-lock brake system
is functioning properly.
• Even with the anti-lock brake system,
your vehicle still requires sufficient
stopping distance. Always maintain a
safe distance from the vehicle in front
of you.
• Always slow down when cornering.
The anti-lock brake system cannot pre-
vent accidents resulting from exces-
sive speeds.
• On loose or uneven road surfaces,
operation of the anti-lock brake system
may result in a longer stopping dis-
tance than for vehicles equipped with a
conventional brake system.
✽NOTICE
When you jump start your vehicle
because of a drained battery, the engine
may not run as smoothly and 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 has malfunctioned.
• Do not pump your brakes!
• Have the battery recharged before
driving the vehicle.

CAUTION
• If the ABS warning light is on and
stays on, you may have a problem
with the ABS. In this case, howev-
er, your regular brakes will work
normally.
• The ABS warning light will stay on
for approximately 3 seconds after
the ignition switch is ON. 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.
CAUTION
• When you drive on a road with
poor traction, such as an icy
road, and have operated your
brakes continuously, the ABS will
be active continuously and the
ABS warning light may illuminate.
Pull your vehicle over to a safe
place and stop the engine.
• Restart the engine. If the ABS
warning light is off, then your
ABS system is normal.
Otherwise, you may have a prob-
lem with the ABS. Contact an
authorized HYUNDAI dealer as
soon as possible.

Electronic stability program (ESP)
(If equipped)
The Electronic Stability Program (ESP)
system is designed to stabilize the
vehicle during cornering maneuvers. ESP
checks where you are steering and where
the vehicle is actually going. ESP applies
the brakes on individual wheels and
intervenes with the engine management
system to stabilize the vehicle.The Electronic Stability Program (ESP)
system is an electronic system designed
to help the driver maintain vehicle control
under adverse conditions. It is not a
substitute for safe driving practices.
Factors including speed, road conditions
and driver steering input can all affect
whether ESP will be effective in
preventing 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 con-
ditions which may lock the wheels, you
may hear a “tik-tik’’ sound from the
brakes, or feel a corresponding sensa-
tion in the brake pedal. This is normal
and it means your ESP is active.
✽NOTICE
A click sound may be heard in the
engine compartment when the vehicle
begins to move after the engine is start-
ed. These conditions are normal and
indicate that the Electronic Stability
Program System is functioning proper-
ly.
WARNING
Never drive too fast according to
the road conditions or too quickly
when cornering. Electronic stability
program (ESP) will not prevent acci-
dents. Excessive speed in turns,
abrupt maneuvers and hydroplan-
ing on wet surfaces can still result
in serious accidents. Only a safe
and attentive driver can prevent
accidents by avoiding maneuvers
that cause the vehicle to lose trac-
tion. Even with ESP installed,
always follow all the normal precau-
tions for driving - including driving
at safe speeds for the conditions.

ESP operation
ESP ON condition
• When the ignition is turned
ON, ESP and ESP OFF indi-
cator lights illuminate for
approximately 3 seconds,
then ESP is turned on.
• Press the ESP OFF button for
at least half a second after
turning the ignition ON to turn
ESP off. (ESP OFF indicator
will illuminate). To turn the
ESP on, press the ESP OFF
button (ESP OFF indicator
light will go off).
• When starting the engine,
you may hear a slight ticking
sound. This is the ESP per-
forming an automatic system
self-check and does not indi-
cate a problem.When operating
When the ESP is in operation,
ESP indicator light blinks.
• When the Electronic Stability
Program is operating properly,
you can feel a slight pulsation
in the vehicle. This is only the
effect of brake control and indi-
cates nothing unusual.
• When moving out of the mud
or slippery road, pressing the
accelerator pedal may not
cause the engine rpm (revo-
lutions per minute) to
increase.

• To cancel ESP operation,
press the ESP OFF button
(ESP OFF indicator light illu-
minates).
• If the ignition switch is turned
to the LOCK position when
ESP is off, ESP remains off.
Upon restarting the engine,
the ESP will automatically
turn on again.

• If your vehicle is equipped with an
automatic transaxle, don't let your
vehicle creep forward. To avoid creep-
ing forward, keep your foot firmly on
the brake pedal when the vehicle is
stopped.
• Be cautious when parking on a hill.
Firmly engage the parking brake and
place the shift lever in P (automatic
transaxle) or in first or reverse gear
(manual transaxle). 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 parking
brake can freeze in the engaged posi-
tion. This is most likely 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 (automatic transaxle) or in
first or reverse gear (manual transaxle)
and block the rear wheels so the vehi-
cle cannot roll. Then release the park-
ing brake.• Do not hold the vehicle on the upgrade
with the accelerator pedal. This can
cause the transaxle to overheat.
Always use the brake pedal or parking
brake.
