ANTI-LOCK BRAKE SYSTEM (ABS)C120A01FC-AATThe Anti-Lock Brake System (ABS) is designed
to prevent wheel lock-up during sudden braking
or on hazardous road surfaces. The ABS con-
trol module monitors the wheel speed and con-
trols the pressure applied to each brake. Thus,
in emergency situations or on slick roads, ABS
will increase vehicle control during braking.NOTE:o A click sound may be heard in the engine
compartment when the vehicle begins
to move after the engine is started. These
conditions are normal and indicate that
the anti-lock brake system (Electronic
Stability Control) is functioning prop-
erly.
o During ABS (ESC) operation, a pulsation
may be felt in the brake pedal when the
brakes are applied. Also, a noise may be
heard in the engine compartment while
braking. These conditions are normal
and indicate that the anti-lock brake
system (Electronic Stability Control Sys-
tem) is functioning properly.
Setting the driver's position1) Be sure the parking brake is engaged.
2) Move the accelerator and brake pedals to
the front most position by pushing the " "
portion of the switch.
3) Adjust the seat position and the steering
wheel angle properly.
4) Move the pedals toward you until you can
fully depress the brake pedal by pushing the
" " portion of the switch.
5) Depress the pedals a few times to get used
to the feel after adjusting.
WARNING:
o Adjust the pedals after parking the ve-
hicle on level ground. Never attempt to
adjust the pedals while the vehicle is
moving.
o Never adjust the pedals with your foot
on the accelerator pedal as this may
result in increasing the engine speed
and acceleration.
o Make sure that you can fully depress the
brake pedal before driving. Otherwise,
you may not be able to hold down the
brake pedal firmly in an emergency stop.
POWER ADJUSTABLE PEDALSC100A01NF-AAT(With Automatic Transaxle) (If Installed)To adjust the position of the accelerator and
brake pedals, turn the ignition key to the "ON"
position with the selector lever in the "P" position
and push the switch.
If you push the " " portion of the switch, the
pedals move rearward.
If you push the " " portion of the switch, the
pedals move forward.

WARNING:
ABS (ESC) will not prevent accidents due to
improper or dangerous driving maneuvers.
Even though vehicle control is improved
during emergency braking, always main-
tain a safe distance between you and ob-
jects ahead. Vehicle speeds should always
be reduced during extreme road condi-
tions.
The braking distance for cars equipped
with an anti-lock braking system (Elec-
tronic 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:
o Rough, gravel or snow-covered roads.
o With tire chains installed.
o On roads where the road surface is pit-
ted or has different surface height.
The safety features of an ABS (ESC)
equipped vehicle should not be tested by
high speed driving or cornering. This could
endanger the safety of yourself or others.
ELECTRONIC STABILITY CONTROL
(ESC) SYSTEMC310A02NF-AAT
The Electronic Stability Control (ESC) system
is designed to stabilize the vehicle during cor-
nering manuevers. 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 con-
ditions 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.
B310A01NF-A
WARNING:
Never drive too fast for the road conditions
or too quickly when cornering. Electronic
stability control (ESC) will not prevent ac-
cidents. Excessive speed in turns, abrupt
maneuvers and hydroplaning on wet sur-
faces can still result in serious accidents.
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
precautions for driving - including driving
at safe speeds for the conditions.

C310D01NF-AATIndicators and WarningThe indicators should illuminate when the igni-
tion key is turned to ON or START but should
go out after three seconds.
If the indicators do not illuminate, or the ESC or
ESC-OFF indicator does not go out after 3
seconds, have the vehicle checked by an
authorized dealer.
Should there be any unusual operation of the
device while driving, the ESC-OFF indicator
illuminates as a warning.
If the ESC-OFF indicator illuminates, drive your
car to a safe place and stop the engine.
Then, start the engine again to check if the ESC-
OFF indicator goes out.
If the indicator remains lit even after the engine
has been started, have your car checked by an
authorized Hyundai dealer.
C310B01NF-AATESC ON/OFF ModeWhen the ESC is operating, the ESC indicator
in the instrument cluster will blink.
If you turn the system off by pressing the ESC
switch, the ESC-OFF indicator will come on and
stay on. In the ESC-OFF mode, the stability
control will be deactivated. Adjust your driving
accordingly. To turn the system back on, press
the switch again. The ESC-OFF indicator should
go off.NOTE:The ESC mode will automatically be turned
ON after the engine is turned off and re-
started.
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 original tires.

!GOOD BRAKING PRACTICESC130A02A-AAT
WARNING:
o 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. Ve-
hicles not fully engaged in park with the
parking brake set are at risk for moving
inadvertently and injuring yourself or
others.
o All vehicles should always have the park-
ing brake fully engaged when parking to
avoid inadvertent movement of the car
which can injure occupants or pedestri-
ans.
o Nothing should be carried on top of the
shelf panel behind the rear seat. If there
were an accident or a sudden stop, such
objects could move forward and cause
damage to the vehicle or injure the occu-
pants.o After being parked, check to be sure the
parking brake is not engaged and that the
parking brake indicator light is out before
driving away.
o 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 your Hyundai dealer for
assistance.
o 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.
o Don't "ride" the brake pedal. Resting your
foot on the brake pedal while driving 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.
o If a tire goes flat while you are driving, 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.o If your car is equipped with an automatic
transaxle, don't let your car creep forward.
To avoid creeping forward, keep your foot
firmly on the brake pedal when the car is
stopped.
o Use caution when parking on a hill. Farmly
engage the parking brake and place the gear
selector lever in "P" (automatic transaxle) or
in first or reverse gear (manual transaxle).
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 conditions to keep the car
from rolling, block the wheels.
o Under some conditions your parking brake
can freeze in the engaged position. 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 while you put
the gear selector lever in "P" (automatic) or
in first or reverse gear (manual transaxle)
and block the rear wheels so the car cannot
roll. Then release the parking brake.
o 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.

SMOOTH CORNERINGC150A01A-AATAvoid braking or gear changing in corners,
especially when roads are wet. Ideally, corners
should always be taken under gentle accelera-
tion. If you follow these suggestions, tire wear
will be held to a minimum.
C160A01A-AATThe more severe weather conditions of winter
result in greater wear and other problems. To
minimize the problems of winter driving, you
should follow these suggestions:C160B01A-AATSnowy or Icy ConditionsTo drive your vehicle in deep snow, it may be
necessary to use snow tires or to install tire
chains on your tires. If snow tires are needed,
it is necessary to select tires equivalent in size
and type of the original equipment tires. Failure
to do so may adversely affect the safety and
handling of your car. Furthermore, speeding,
rapid acceleration, sudden brake applications,
and sharp turns are potentially very hazardous
practices.
During deceleration, use engine braking to the
fullest extent. Sudden brake applications on
snowy or icy roads may cause skids to occur.
You need to keep sufficient distance between
the vehicle in operation in front and your vehicle.
Also, apply the brake gently. It should be noted
that installing tire chains on the tire will provide
a greater driving force, but will not prevent side
skids.NOTE:Tire chains are not legal in all states. Check
state laws before fitting tire chains.WINTER DRIVING
C160D01A-AATCheck Battery and CablesWinter puts additional burdens on the battery
system. Visually inspect the battery and cables
as described in Section 6. The level of charge
in your battery can be checked by your Hyundai
dealer or a service station.C160C01A-AATUse High Quality Ethylene Glycol
CoolantYour Hyundai is delivered with high quality
ethylene glycol coolant in the cooling system. It
is the only type of coolant that should be used
because it helps prevent corrosion in the cool-
ing system, lubricates the water pump and
prevents freezing. Be sure to replace or replen-
ish your coolant in accordance with the main-
tenance schedule in Section 5. Before winter,
have your coolant tested to assure that its
freezing point is sufficient for the temperatures
anticipated during the winter.

C160J01A-AATDon't Let Ice and Snow Accumulate
UnderneathUnder some conditions, snow and ice can build
up under the fenders and interfere with the
steering. When driving in severe winter condi-
tions where this may happen, you should peri-
odically check underneath the car to be sure the
movement of the front wheels and the steering
components is not obstructed.C160I01A-AATDon't Let Your Parking Brake FreezeUnder some conditions your parking brake can
freeze in the engaged position. 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 the
parking brake may freeze, apply it only tempo-
rarily while you put the gear selector lever in "P"
(automatic) or in first or reverse gear (manual
transaxle) and block the rear wheels so the car
cannot roll. Then release the parking brake.
C160H02A-AATUse Approved Window Washer Anti-
Freeze in SystemTo keep the water in the window washer system
from freezing, add an approved window washer
anti-freeze solution in accordance with instruc-
tions on the container. Window washer anti-
freeze is available from Hyundai dealers and
most auto parts outlets. Do not use engine
coolant or other types of anti-freeze as these
may damage the paint finish.C160G01A-AATTo Keep Locks from FreezingTo keep the locks from freezing, squirt an
approved de-icer fluid or glycerine into the key
opening. If a lock is covered with ice, squirt it with
an approved de-icing fluid to remove the ice. If
the lock is frozen internally, you may be able to
thaw it out by using a heated key. Handle the
heated key with care to avoid injury.
C160F01A-AATCheck Spark Plugs and Ignition
SystemInspect your spark plugs as described in Sec-
tion 6 and replace them if necessary. Also
check all ignition wiring and components to be
sure they are not cracked, worn or damaged in
any way.C160E01A-AATChange to "Winter Weight" Oil if
NecessaryIn some climates it is recommended that a lower
viscosity "winter weight" oil be used during cold
weather. See Section 9 for recommendations.
If you aren't sure what weight oil you should use,
consult your Hyundai dealer.

WHAT TO DO IN AN EMERGENCY
CHANGING A FLAT TIRE
IF YOU HAVE A FLAT TIRE
D060A01A-AATThe procedure described on the follow-
ing pages can be used to rotate tires as
well as to change a flat tire. When
preparing to change a flat tire, check to
be sure the gear selector lever is in "P"
(automatic transaxle) or reverse gear
(manual transaxle) and that the parking
brake is set, then:
D050A01A-AATIf a tire goes flat while you are driving:
1. Take your foot off the accelerator pedal
and let the car slow down while driving
straight ahead. Do not apply the brakes
immediately or attempt to pull off the
road as this may cause a loss of
control. When the car has slowed to
such a speed that it is safe to do so,
brake carefully and pull off the road.
Drive off the road as far as possible
and park on firm, level ground. If you
are on a divided highway, do not park
in the median area between the two
traffic lanes.
2. When the car is stopped, turn on your
emergency hazard flashers, set the
parking brake and put the transaxle in
"P" (automatic) or reverse (manual
transaxle).
3. Have all passengers get out of the car.
Be sure they all get out on the side of
the car that is away from traffic.
4. Change the tire according to the in-
structions provided as follows.
D060A01NF-A
D040B01NF-GATHandling the Spare Tire
To remove the spare tire, take out the
tool receptacle and remove the installa-
tion bolt by turning it counterclockwise.
To replace the spare tire in its storage
compartment, tighten the bolt firmly
with your fingers until there is no more
play in the spare tire.

CORROSION PREVENTION AND APPEARANCE CARE
3
WASHING AND WAXING
E020E01A-AATDon't Neglect the InteriorMoisture can collect under the floor mats and
carpeting to cause corrosion. Check under the
mats periodically to be sure the carpeting is dry.
Use particular care if you carry fertilizers, clean-
ing materials or chemicals in the car.
These should be carried only in proper contain-
ers and any spills or leaks should be cleaned up,
flushed with clean water and thoroughly dried.
E020C01A-AATKeep Your Garage DryDon't park your car in a damp, poorly ventilated
garage. This creates a favorable environment
for corrosion. This is particularly true if you
wash your car in the garage or drive it into the
garage when it is still wet or covered with snow,
ice or mud. Even a heated garage can contrib-
ute to corrosion unless it is well ventilated so
moisture is dispersed.
E030A02A-AATWashing Your HyundaiNever wash your car when the surface is hot
from being in the sun. Always wash your car in
the shade.
Wash your car frequently. Dirt is abrasive and
can scratch the paint if it is not removed. Air
pollution or acid rain may damage the paint and
trim through chemical action if pollutants are
allowed to remain in contact with the surface. If
you live near the ocean or in an area where road
salts or dust control chemicals are used, you
should pay particular attention to the underside
of the car. Start by rinsing the car to remove dust
and loose dirt. In winter, or if you have driven
through mud or muddy water, be sure to thor-
oughly clean the underside as well. Use a hard
direct stream of water to remove accumulations
of mud or corrosive materials. Use a good
quality car-washing solution and follow the
manufacturer's directions on the package.
These are available at your Hyundai dealer or
auto parts outlet. Don't use strong household
detergents, gasoline, strong solvents or abra-
sive cleaning powders as these may damage
the finish.
Use a clean sponge or cloth, rinse it frequently
and don't damage the finish by rubbing too hard.
For stubborn spots, dampen them frequently
and remove them a little at a time. o When cleaning lower door panels, rocker
panels and frame members, be sure that
drain holes are kept open so that moisture
can escape and not be trapped inside to ac-
celerate corrosion.
E020D02A-AATKeep Paint and Trim in Good ConditionScratches or chips in the finish should be
covered with "touch-up" paint as soon as pos-
sible to reduce the possibility of corrosion. If
bare metal is showing through, the attention of
a qualified body and paint shop is recommended.
Bird droppings : Bird droppings are highly cor-
rosive and may damage painted surfaces in just
a few hours. Always remove bird droppings as
soon as possible.
