Anti-lock Brake System (ABS)
OLF044407NOLF046409N
An Anti-Lock Braking System
(ABS) or an Electronic Stability
Control (ESC) system will not
prevent accidents due to
improper or dangerous driving
maneuvers. Even though vehi-
cle control is improved during
emergency braking, always
maintain a safe distance
between you and objects ahead
of you. Vehicle speeds should
always be reduced during
extreme road conditions. The
braking distance for cars
equipped with ABS or ESC may
be longer than for those without
these systems in the following
road conditions.(Continued)
WARNING

5-41
Driving your vehicle

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.

Driving your vehicle
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
OLF054448

5-44
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.
