Disc brakes wear indicator
When your brake pads are worn and
new pads are required, you will hear
a high pitched warning sound from
your front or rear brakes. You mayhear this sound come and go or it
may occur whenever you depress
the brake pedal.
Note that some driving conditions or
climates may cause a brake squeal
when you first apply (or lightly apply)
the brakes. This is normal and does
not indicate a problem with your
brakes.
To avoid costly brake repairs, do
not continue to drive with wornbrake pads.
Information
Always replace brake pads as com-
plete front or rear axle sets.
Parking brake
Applying the parking brake
Always set the parking brake before
leaving the vehicle.

Driving your vehicle
Do not apply the acceleratorpedal while the parking brake is
engaged. If you depress theaccelerator pedal with the park-
ing brake engaged, warning will
sound. Damage to the parking
brake may occur.
Driving with the parking brake on can overheat the braking systemand cause premature wear or
damage to brake parts. Make surethe parking brake is released and
the Brake Warning Light is off
before driving. Check the Parking
Brake Warning Light
by placing the ignition
switch to the ON posi-
tion (do not start the
vehicle).
This light will be illuminated when the
parking brake is applied with the igni-
tion switch in the START or ON posi-tion.
Before driving, be sure the parking
brake is released and the Brake
Warning Light is OFF. If the Parking Brake Warning Light
remains on after the parking brake is
released while the vehicle is on,
there may be a malfunction in the
brake system. Immediate attention is
necessary.
If at all possible, cease driving the
vehicle immediately. If that is not pos-
sible, use extreme caution while
operating the vehicle and only con-
tinue to drive the vehicle until you
can reach a safe location.
NOTICE

5-30
Driving your vehicle
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 gothrough 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. We recom-
mend that you contact an authorized
HYUNDAI dealer as soon as possi-
ble.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 ABSsystem is normal.
Otherwise, you may have a prob-
lem with your ABS system. We
recommend that you 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 normal-
ly. To reduce the risk of serious
injury or death, we recommend
that you contact your 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. After both
lights go off, the ESC is enabled.

Type A
■Type B
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 hydroplaningon wet surfaces can result in
severe accidents.
WARNING

Driving your vehicle
When operating
When the ESC is in opera- tion, the ESC indicator light
blinks:
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.
cle may not respond to the acceler-ator as it does under routine condi-
tions.
when the ESC activates, the Cruise
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)
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 stability and traction
of the vehicle and does not indicate
a problem.
ESC OFF condition
To cancel ESC operation :

Press the ESC OFF button briefly. The ESC OFF indicator light and
message "Traction Control disabled"
will illuminate. In this state, the trac-tion control function of ESC (engine
management) is disabled, but the
brake control function of ESC (brak-
ing management) still operates.
Press and hold the ESC OFF button
continuously for more than 3 sec-
onds. The ESC OFF indicator light
and message "Traction & Stability
Control disabled" illuminates and a
warning chime sounds. In this state,
both the traction control function ofESC (engine management) and the
brake control function of ESC (brak-
ing management) are disabled.
If the ignition switch is placed to the
LOCK/OFF position when ESC is off,
ESC remains off. Upon restarting the
vehicle, the ESC will automatically
turn on again.

Driving your vehicle
To prevent damage to the trans- mission:
Do not allow wheel(s) of one axleto spin excessively while the
ESC, ABS, and parking brake
warning 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, make sure theESC is turned off (ESC OFF lightilluminated).
Information
Turning the ESC off does not affect
ABS or standard brake system opera-
tion.
Vehicle Stability Management (VSM)
The Vehicle Stability Management (VSM) is a function of the Electronic
Stability Control (ESC) system. It
helps ensure the vehicle stays stable
when accelerating or braking sud-
denly on wet, slippery and rough
roads where traction over the four
tires can suddenly become uneven.
VSM operation
VSM ON condition
The VSM operates when:
The Electronic Stability Control (ESC) is on.
Vehicle speed is approximately above 15 km/h (9 mph) on curve
roads.
Vehicle speed is approximately above 20 km/h (12 mph) when the
vehicle is braking on rough roads.
When operating
When you apply your brakes under
conditions which may activate the
ESC, you may hear sounds from the
brakes, or feel a corresponding sen-
sation in the brake pedal. This is nor-
mal and it means your VSM is active.
i
NOTICE
Take the following precautions
when using the Vehicle Stability
Management (VSM):
ALWAYS check the speed and
the distance to the vehicle
ahead. The VSM is not a substi-
tute for safe driving practices.
Never drive too fast for the
road conditions. The VSM sys-
tem will not prevent acci-
dents. Excessive speed in bad
weather, slippery and uneven
roads can result in severeaccidents.
WARNING

Driving your vehicle
Hill-Start Assist Control (HAC) (if equipped)
A vehicle has the tendency to slide
backwards on a steep slope, before
depressing the accelerator after a
stop. The HAC prevents the vehicle
from sliding backwards by automati-
cally operating the brake systems for
about 2 seconds. The brake systemsare automatically released, when the
accelerator pedal is depressed.Information
 The HAC does not operate when the shift lever is in P (Park) or N (Neutral).
 The HAC activates even when the ESC (Electronic Stability Control) is
off. However, it does not activate,
when the ESC does not normally
operate.
Emergency Stop Signal (ESS) (if equipped)
The Emergency Stop Signal system
alerts the driver behind by blinking
the stop lights, while sharply and
severely braking.
The system is activated when:
The vehicle suddenly stops. (Thedeceleration power exceeds 7 m/s 2
,
and the driving speed exceeds 55 km/h (34 mph).)
The ABS is activated.
The hazard warning flasher automat-
ically turns ON after blinking the stop
lights, when the driving speeds is
decelerated under 40 km/h (25 mph),
when the ABS is deactivated, and
when the sudden braking situation is
over. The hazard warning flasher turns
OFF, when the driving speed exceeds10 km/h (6 mph) after a complete
stop. The hazard warning flasher
turns OFF, when the vehicle drives at
a low speed for a certain period of
time. The driver can manually turn
OFF the hazard warning flasher by
pressing the button.
Information
The Emergency Stop Signal (ESS) sys-
tem will not work if the hazard warn-
ing flasher already blinks.

i
The HAC is activated only for
about 2 seconds, so alwaysdepress the accelerator pedal
to begin driving upwards after astop.

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. If the braking action does
not return to normal, stop as soon as
it is safe to do so and we recommend
that you call an authorized HYUNDAI
dealer for assistance.
DO NOT drive with your foot resting
on the brake pedal. Even light, butconstant 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 LOCK/OFF posi-tion.
Vehicles parked with the park- ing brake not applied or not
fully engaged may roll inadver-
tently and may cause injury to
the driver and others. ALWAYS
apply the parking brake before
exiting the vehicle.
