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
POWER button 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)
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.

5-38
Driving your vehicle
When you drive on a road having
poor traction, such as an icy road,
and apply your brakes continu-
ously, the ABS will be active con-
tinuously and the ABS warning
light ( ) may illuminate. Pull
your car over to a safe place and
turn the vehicle off.
Restart the vehicle. If the ABS
warning light is off, then your ABS
system is normal.
Otherwise, you may have a prob-
lem with your ABS system.
Contact an authorized HYUNDAI
dealer as soon as possible.
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.
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 electric vehicle
control 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.
i
NOTICE
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 operating
When the ESC is in opera-
tion, the ESC indicator light

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.

ator as it does under routine condi-
tions.

Control automatically disengages.
The Cruise Control can be reen-
gaged when the road conditions
allow.See "Cruise Control System"
later in this chapter.(if equipped) 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
