Disc brakes wear indicator
Your vehicle has disc brakes.
When your brake pads are worn and new
pads are required, you will hear a high-
pitched warning sound from your front
brakes or rear brakes. You may hear this
sound come and go or it may occur
whenever you depress the brake pedal.
Please remember that some driving con-
ditions 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.

WARNING
To prevent unintentional move- ment when stopped and leaving
the vehicle, do not use the
gearshift lever in place of the
parking brake. Set the parkingbrake AND make sure the
gearshift lever is securely posi-
tioned in 1st (First) gear or R
(Reverse) for manual transaxle
equipped vehicles and in P (Park)
for automatic transaxle equipped
vehicles.
Never allow anyone who is unfa- miliar with the vehicle to touch
the parking brake. If the parking
brake is released unintentionally,
serious injury may occur.
All vehicles should always have the parking brake fully engaged
when parking to avoid inadver-
tent movement of the vehicle
which can injure occupants orpedestrians.

Check the brake warning light by turning
the ignition switch ON (do not start the
engine). This light will be illuminated
when the parking brake is applied with
the ignition switch in the START or ONposition.
Before driving, be sure the parking brake
is fully released and the brake warning
light is off.
If the brake warning light remains on
after the parking brake is released whilst
engine is running, there may be a mal-
function in the brake system. Immediate
attention is necessary.
If at all possible, cease driving the vehi-
cle immediately. If that is not possible,
use extreme caution whilst operating the
vehicle and only continue to drive the
vehicle until you can reach a safe loca-
tion or repair shop. Anti-lock brake system (ABS) (if equipped)
W-75
(Continued)
On roads where the road surface
is pitted or has different surface height.
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.
WARNING
ABS (or ESP) will not prevent acci-
dents due to improper or danger-
ous driving manoeuvres. 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 cars
equipped with an anti-lock braking
system (or 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 reducedspeeds:
Rough, gravel or snow-covered roads.
With tyre chains installed. (Continued)

525
Driving your vehicle
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 sensation
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. Press your brake pedal as
hard as possible or as hard as the situa-
tion warrants and allow the ABS to con-
trol the force being delivered to the
brakes.✽✽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.
W-78
CAUTION
If the ABS warning light is on and
stays on, you may have a problemwith the ABS. In this case, howev- er, your regular brakes will worknormally.
The ABS warning light will stay on for approximately 3 seconds afterthe ignition switch is ON. During that time, the ABS will go throughself-diagnosis and the light will gooff if everything is normal. If thelight stays on, you may have aproblem with your ABS. Contactan authorised HYUNDAI dealer as soon as possible.

✽✽
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 is malfunctioning.
 Do not pump your brakes!
 Have the battery recharged before driving the vehicle.
Electronic stability program (ESP) (if equipped)
The Electronic Stability Program (ESP)
system is designed to stabilize the vehicle
during cornering manoeuvres. ESP
checks where you are steering and where
the vehicle is actually going.
ESP applies the brakes at individual
wheels and intervenes in the engine
management system to stabilize the
vehicle.
CAUTION
When you drive on a road having
poor traction, such as an icy road,
and operate 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 stop theengine.
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 anauthorised HYUNDAI dealer as
soon as possible.WARNING
Never drive too fast for the road
conditions or too quickly when cor-
nering. Electronic stability program
(ESP) will not prevent accidents.
Excessive speed in turns, abrupt
manoeuvres and hydroplaning onwet surfaces can still result in seri-
ous accidents. Only a safe and
attentive driver can prevent acci-
dents by avoiding manoeuvres that
cause the vehicle to lose traction.
Even with ESP installed, always fol-
low all the normal precautions for
driving - including driving at safe
speeds for the conditions.

Driving your 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 sensation
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.

ESP OFF usage
When driving
ESP should be turned on for daily driv-ing whenever possible.
To turn ESP off whilst driving, press the ESP OFF button whilst driving on a
flat road surface.
Never press the ESP OFF button whilst
ESP is operating (ESP indicator light
blinks).
If ESP is turned off whilst ESP is operat-
ing, the vehicle may slip out of control.
✽✽ NOTICE
 When operating the vehicle on a dynamometer, ensure that the ESP is
turned off (ESP OFF light illuminat-
ed).
 Turning the ESP off does not affect
ABS or brake system operation.
Hill-start assist control (HAC) (if equipped)
A vehicle has the tendency to slip back
on a steep hill when it starts to go after
stopping. The Hill-start Assist Control
(HAC) prevents the vehicle from slipping
back by operating the brakes automati-
cally for about 2 seconds. The brakes are
released when the accelerator pedal is
depressed or after about 2 seconds.
✽✽ NOTICE
 The HAC does not operate when the transaxle shift lever is in the P (Park)
or N (Neutral) position.
 The HAC activates even though the ESP is off but it does not activate
when the ESP has malfunctioned.
WARNING
Never press the ESP OFF button whilst ESP is operating. If the ESP is turned off whilst ESP
is operating, the vehicle may go out
of control.
To turn ESP off whilst driving,
press the ESP OFF button whilst
driving on a flat road surface.
WARNING
The HAC is activated only for about
2 seconds, so when the vehicle is
starting off always depress theaccelerator pedal.

Good braking practices
After parking the vehicle, check to be
sure the parking brake is not engaged
and that the parking brake indicator
light is out before driving away.
Driving through water may get the brakes wet. They can also get wet
when the car is washed. Wet brakes
can be dangerous! Your car will not
stop as quickly if the brakes are wet.
Wet brakes may cause the car to pull
to one side. To dry the brakes, apply the brakes
lightly until the braking action returns to
normal, taking care to keep the car
under control at all times. If the braking
action does not return to normal, stop
as soon as it is safe to do so and call
an authorised HYUNDAI dealer for
assistance.
Don't coast down hills with the car out of gear. This is extremely hazardous.
Keep the car in gear at all times, use
the brakes to slow down, then shift to a
lower gear so that engine braking will
help you maintain a safe speed.
Don't "ride" the brake pedal. Resting your foot on the brake pedal whilst driv-ing can be dangerous because it can
result in the brakes overheating and
losing their effectiveness. It also
increases the wear of the brake com-
ponents.
If a tyre goes flat whilst you are driving, apply the brakes gently and keep the
car pointed straight ahead whilst 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
place. If your car is equipped with an auto-
matic transaxle, don't let your car
creep forward. To avoid creeping for-
ward, keep your foot firmly on the
brake pedal when the car is stopped.
Use caution when parking on a hill. Firmly engage the parking brake and
place the shift lever in P. If your car is
facing downhill, turn the front wheels
into the kerb to help keep the car from
rolling. If your car is facing uphill, turn
the front wheels away from the kerb to
help keep the car from rolling. If there
is no kerb or if it is required by other
conditions to keep the car 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 whilst you put the shift lever
in P and block the rear wheels so the
car 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.
WARNING
Whenever leaving vehicle or parking, always set the parking
brake as far as possible and fully
engage the vehicle's transaxle
into the park position. Vehicles
not fully engaged in park with the
parking brake set are at risk for
moving inadvertently and injur-
ing yourself or others.
All vehicles should always have the parking brake fully engaged
when parking to avoid inadver-
tent movement of the car whichcan injure occupants or pedestri-ans.
