EPB malfunction indicator (if equipped)
This warning light illuminates if the
Engine Start/Stop button is changed
to the ON position and goes off in
approximately 3 seconds if the sys-
tem is operating normally.
If the EPB malfunction indicator
remains on, comes on while driving,
or does not come on when the
Engine Start/Stop button is changed
to the ON position, this indicates that
the EPB may have malfunctioned. If this occurs, have the system
checked by an authorized HYUNDAI
dealer.
The EPB malfunction indicator may
illuminate when the ESC indicator
comes on to indicate that the ESC is
not working properly, but it does not
indicate a malfunction of the EPB.
If the EPB warning light is still
on, we recommend that the sys-
tem be checked by an author-
ized HYUNDAI dealer.
If the parking brake warning light ( , red color) does not
illuminate or blinks even though
the EPB switch was pulled up,
the EPB may not be applied.
If the parking brake warning light ( , red color) blinks when
the EPB warning light is on,
press the switch, and then pull it
up. Repeat this one more time. If
the EPB warning does not go
off, have the system checked by
an authorized HYUNDAI dealer.

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
Engine Start/Stop 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 nor-
mal. If the light stays on, you may
have a problem with your ABS.
Contact an authorized HYUNDAI
dealer as soon as possible.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 engine off.
Restart the engine. 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.
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 normally.
To reduce the risk of serious
injury or death, contact your
HYUNDAI dealer as soon as pos-
sible.
WARNING

Driving your 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 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 Engine Start/Stop button
is in the ON position, the ESC and
the ESC OFF indicator lights illumi-
nate for approximately three seconds
and goes off, then the ESC is turned
on.
OLF057448
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.

gaged when the road conditions
allow. See "Cruise Control System"
later in this chapter.
driving on a slippery road, the
engine rpm (revolutions per minute)

the accelerator pedal deeply. This is
to maintain the stability and traction
of the vehicle and does not indicate
a problem.

To cancel ESC operation :

Press the ESC OFF button briefly.
