Check the brake warning light by turn-
ing the ignition switch ON (do not start
the engine). This light will be illuminat-
ed when the parking brake is applied
with the ignition switch in the START
or ON position.
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
while engine is running, there may be
a malfunction in the brake system.
Immediate attention is necessary.
WARNING
To prevent unintentional move-
ment when stopped and leav-
ing the vehicle, do not use the
gearshift lever in place of the
parking brake. Set the parking
brake AND make sure the
gearshift lever is securely posi-
tioned in 1st (First) gear or R
(Reverse) for manual transmis-
sion equipped vehicles and in
P (Park) for automatic trans-
mission equipped vehicles.
Never allow anyone who is
unfamiliar with the vehicle to
touch the parking brake. If the
parking brake is released unin-
tentionally, serious injury may
occur.
All vehicles should always
have the parking brake fully
engaged when parking to avoid
inadvertent movement of the
car which can injure occupants
or pedestrians.
W-75
CAUTION
Do not operate the parking
brake while the vehicle is mov-
ing except in an emergency sit-
uation. It could damage the
vehicle system and endanger
driving safety.

529
Driving your vehicle
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 or repair
shop.Anti-lock brake system (ABS)
The ABS continuously senses the
speed of the wheels. If the wheels
are going to lock, the ABS system
repeatedly modulates the hydraulic
brake pressure to the wheels.
When you apply your brakes under
conditions which may lock the
wheels, you may hear a “tik-tik’’
sound from the brakes, or feel a cor-
responding sensation in the brake
pedal. This is normal and it means
your ABS is active.
In order to obtain the maximum ben-
efit from your ABS in an emergency
situation, 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 situation warrants and allow
the ABS to control the force being
delivered to the brakes.
WARNING
ABS (or ESC) will not prevent
accidents due to improper or
dangerous driving maneuvers.
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 brak-
ing system (or Electronic
Stability Control system) may be
longer than for those without it in
the following road conditions.
During these conditions the
vehicle should be driven at
reduced speeds:
Rough, gravel or snow-cov-
ered roads.
With tire chains installed.
On roads where the road sur-
face is pitted or has different
surface height.
(Continued)
(Continued)
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.

✽
✽
NOTICE
A click sound may be heard in the
engine compartment when the vehi-
cle begins to move after the engine is
started. These conditions are normal
and indicate that the anti-lock brake
system is functioning properly.
Even with the anti-lock brake sys-
tem, your vehicle still requires suf-
ficient 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
prevent accidents resulting from
excessive speeds.
On loose or uneven road surfaces,
operation of the anti-lock brake
system may result in a longer stop-
ping distance than for vehicles
equipped with a conventional
brake system.
✽ ✽
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 malfunc-
tioning.
• Do not pump your brakes!
• Have the battery recharged before
driving the vehicle.
W-78
CAUTION
If the ABS warning light is on
and stays on, you may have a
problem with the ABS. In this
case, however, your regular
brakes will work normally.
The ABS warning light will stay
on for approximately 3 seconds
after the ignition switch is ON.
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 author-
ized HYUNDAI dealer as soon
as possible.
CAUTION
When you drive on a road hav-
ing poor traction, such as an
icy road, and operate your
brakes continuously, the ABS
will be active continuously and
the ABS warning light may illu-
minate. Pull your car over to a
safe place and stop the engine.
Restart the engine. If the ABS
warning light is off, then your
ABS system is normal.
Otherwise, you may have a
problem with the ABS. Contact
an authorized HYUNDAI dealer
as soon as possible.

Driving your vehicle
Electronic stability control
(ESC)
The Electronic Stability control (ESC)
system is designed to stabilize the
vehicle during cornering maneuvers.
ESC checks where you are steering
and where the vehicle is actually
going. ESC applies the brakes at
individual wheels and intervenes in
the engine management system to
stabilize the vehicle.The Electronic Stability Control
(ESC) 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 ESC 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
conditions which may lock the
wheels, you may hear a “tik-tik’’
sound from the brakes, or feel a cor-
responding sensation in the brake
pedal. This is normal and it means
your ESC is active.
✽ ✽
NOTICE
A click sound may be heard in the
engine compartment when the vehi-
cle begins to move after the engine is
started. These conditions are normal
and indicate that the Electronic
Stability Control System is function-
ing properly.
WARNING
Never drive too fast for the road
conditions or too quickly when
cornering. Electronic stability
control (ESC) will not prevent
accidents. Excessive speed in
turns, abrupt maneuvers and
hydroplaning on wet surfaces
can still result in serious acci-
dents. Only a safe and attentive
driver can prevent accidents by
avoiding maneuvers that cause
the vehicle to lose traction.
Even with ESC installed, always
follow all the normal precau-
tions for driving - including driv-
ing at safe speeds for the condi-
tions.

ESC off state 1
To cancel ESC operation, press the
ESC OFF button (ESC OFF )
shortly (ESC OFF indicator light
(ESC OFF ) illuminates). At this
state, the engine control function
does not operate. It means the trac-
tion control function does not oper-
ate. Brake control function only
operates.ESC off state 2
To cancel ESC operation, press the
ESC OFF button (ESC OFF ) for
more than 3 seconds. ESC OFF
indicator light (ESP OFF ) illumi-
nates and ESP OFF warning chime
will sound. At this state, the engine
control function and brake control
function do not operate. It means
the vehicle stability control function
does not operate any more.
ESC indicator (Electronic
Stability Control)
The ESC indicator will illuminate
when the ignition switch is turned
ON, but should go off after approxi-
mately 3 seconds. When the ESC is
on, it monitors the driving conditions
and under normal driving conditions,
the ESC indicator will remain off.
When a slippery or low traction con-
dition is encountered, the ESC will
operate, and the ESC indicator
will blink to indicate the ESC is oper-
ating.
If ESC indicator illuminates while
ESC is operating, the ESC may have
a malfunction. Take your car to an
authorized HYUNDAI dealer and
have the system checked.

ESC OFF indicator
The ESC OFF indicator will illumi-
nate when the ignition switch is
turned ON, but should go off after
approximately 3 seconds. To switch
to ESC OFF mode, press the ESC
OFF button . The ESC OFF indica-
tor will illuminate indicating the
ESC is deactivated.
If this indicator stays on when ESC
OFF is not selected, the ESC may
have a malfunction. Take your car to
an authorized HYUNDAI dealer and
have the system checked.
With the ESC system in the stand by
position, if you use the parking brake
to stop the vehicle due to abnormal
brake operation, the ESC system
may be stopped and ESC OFF indi-
cator may illuminate for about 5
minutes.
ESC OFF usage
When driving
ESC should be turned on for daily
driving whenever possible. If ESC
is turned off, it may be difficult to
make a turn or drive up a hill.
To turn ESC off while driving, press
the ESC OFF button while driv-
ing on a flat road surface.
Never press the ESC OFF button
while ESC is operating (ESC indica-
tor light blinks).
If ESC is turned off while ESC is
operating, it may be very dangerous
because of unexpected vehicle slip.
✽ ✽
NOTICE
• When operating the vehicle on a
dynamometer, ensure that the
ESC is turned off (ESC OFF light
illuminated). If the ESC is left
on, it may prevent the vehicle
speed from increasing, and result
in false diagnosis.
• Turning the ESC off does not
affect ABS or brake system opera-
tion.
CAUTION
Driving with varying tire or
wheel sizes may cause the ESC
system to malfunction. When
replacing tires, make sure they
are the same size as your origi-
nal tires.
WARNING
The Electronic Stability Control
system is only a driving aid; use
precautions for safe driving by
slowing down on curved, snowy,
or icy roads. Drive slowly and
don’t attempt to accelerate
whenever the ESC indicator
light is blinking, or when the
road surface is slippery.
CAUTION
Do not use the parking brake to
stop the vehicle, except in an
emergency situation.

535
Driving your vehicle
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 automatically for about 2 sec-
onds. 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 acti-
vate when the ESP has malfunc-
tioned.
• The HAC applies only to vehicles
with manual transmission.
Good braking practicesWARNING
Never press the ESC OFF but-
ton while ESC is operating.
If the ESC is turned off while
ESC is operating, the vehicle
may go out of control.
To turn ESC off while driving,
press the ESC OFF button
while driving on a flat road sur-
face.WARNING
Whenever leaving vehicle or
parking, always set the park-
ing brake as far as possible
and fully engage the vehicle's
transmission into the park
position. Vehicles not fully
engaged in park with the park-
ing brake set are at risk for
moving inadvertently and
injuring yourself or others.
All vehicles should always
have the parking brake fully
engaged when parking to
avoid inadvertent movement
of the car which can injure
occupants or pedestrians.
WARNING
The HAC is activated only for
about 2 seconds, so when the
vehicle is starting off always
depress the accelerator pedal.

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
authorized HYUNDAI dealer for
assistance.
Don't coast down hills with the car
out of gear. This is extremely haz-
ardous. 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 while driving can be danger-
ous because it can result in the
brakes overheating and losing their
effectiveness. It also increases the
wear of the brake components.
If a tire goes flat while you are driv-
ing, apply the brakes gently and
keep the car 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 place.
If your car is equipped with an
automatic transmission, don't let
your car creep forward. To avoid
creeping forward, 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 curb to help keep
the car from rolling. If your car is
facing uphill, turn the front wheels
away from the curb to help keep
the car from rolling. If there is no
curb or if it is required by other con-
ditions to keep the car from rolling,
block the wheels.
Under some conditions your park-
ing brake can freeze in the
engaged position. This is most like-
ly 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 while you
put the shift lever in P (automatic
transmission) and block the rear
wheels so the car cannot roll. Then
release the parking brake.
Do not hold the vehicle on an uphill
with the accelerator pedal. This can
cause the transmission to over-
heat. Always use the brake pedal
or parking brake.

537
Driving your vehicle
The cruise control system allows you
to program the vehicle to maintain a
constant speed without pressing the
accelerator pedal.
This system is designed to function
above approximately 25 mph (40
km/h).✽ ✽
NOTICE
During normal cruise control opera-
tion, when the SET switch is activat-
ed or reactivated after applying the
brakes, the cruise control will ener-
gize after approximately 3 seconds.
This delay is normal.
✽ ✽
NOTICE
To activate cruise control, depress
the brake pedal at least once after
turning the ignition switch to the ON
position or starting the engine. This
is to check if the brake switch which
is important part to cancel cruise
control is in normal condition.
CRUISE CONTROL SYSTEM (IF EQUIPPED)
WARNING
If the cruise control is left on,
(CRUISE indicator light in the
instrument cluster illuminat-
ed) the cruise control can be
switched on accidentally.
Keep the cruise control sys-
tem off (CRUISE indicator
light OFF) when the cruise
control is not in use, to avoid
inadvertently setting a speed.
Use the cruise control system
only when traveling on open
highways in good weather.
(Continued)
(Continued)
Do not use the cruise control
when it may not be safe to
keep the car at a constant
speed, for instance, driving in
heavy or varying traffic, or on
slippery (rainy, icy or snow-
covered) or winding roads or
over 6% up-hill or down-hill
roads.
Pay particular attention to the
driving conditions whenever
using the cruise control sys-
tem.
Be careful when driving down-
hill using the cruise control
system, which may increase
the vehicle speed.
WARNING- Misuse cruise
control
Do not use cruise control if the
traffic situation does not allow
you to drive safely at a constant
speed and with sufficient dis-
tance to the vehicle in front.
