C120A02A-AATANTI-LOCK BRAKE SYSTEM
(If installed)
The 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:During ABS operation, a slight 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 is
functioning properly.
C090N01O-AATGood Driving Practices
o Never move the gear selector lever from "P"
or "N" to any other position with the accelera-
tor pedal depressed.
o Never move the gear selector lever into "P"
when the vehicle is in motion.
o Be sure the car is completely stopped before
you attempt to shift into "R".
o Never take the car out of gear and coast
down a hill. This may be extremely hazard-
ous. Always leave the car in gear when
moving.
o Do not "ride" the brakes. This can cause
them to overheat and malfunction. Instead,
when you are driving down a long hill, slow
down and shift to a lower gear. When you do
this, engine braking will help slow the car.
o Slow down before shifting to a lower gear.
Otherwise, the lower gear may not be en-
gaged.
o Always use the parking brake. Do not de-
pend on placing the transaxle in "P" to keep
the car from moving.
o Exercise extreme caution when driving on a
slippery surface. Be especially careful when
braking, accelerating or shifting gears. On a
slippery surface, an abrupt change in ve-
hicle speed can cause the drive wheels to
lose traction and the vehicle to go out of
control.
WARNING:ABS will not prevent accidents due to im-
proper 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 may be
longer than for those without it in the
following road conditions.
WARNING:o Avoid high cornering speeds.
o Do not make quick steering wheel move-
ments, such as sharp lane changes or
fast, sharp turns.
o Always wear your seat belts.
In a collision crash, un unbelted person
is significantly more likely to die than a
person wearing a seatbelt.
o The risk of rollover is greatly increased if
you lose control of your vehicle at high-
way speeds.
o Loss of control often occurs if two or
more wheels drop off the roadway and
the driver oversteers to reenter the road-
way.
o In the event your vehicle leaves the road-
way, do not steer sharply. Instead, slow
down before pulling back into the travel
lanes.
o Never exceed posted speed limits.

C130A01A-AATGOOD BRAKING PRACTICES
WARNING:
Nothing should be carried on top of the
cargo area cover 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 on
the brake pedal when the car is stopped.
o Use caution when parking on a hill. Engage
the parking brake and place the gear selec-
tor 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 ac-
cumulation 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
C300D02L-GATIndicator and Warning
The indicator should illuminate when the ignition
key is turned to "ON" or "start", but should go
out after three seconds.
If the indicator does not illuminate, have it checked
by an authorized Hyundai dealer.
Should there be any unusual conditions in the
device, TCS illuminates as a warning.
If TCS illuminates, pull your car to a safe place
and stop the engine.
Then, start the engine again to check if the TCS
indicator goes out.
If the indicator remains lit even after the engine
has been started, have your car checked by an
authorized Hyundai dealer.
NOTE:1) When TCS illuminates, traction control
is automatically deactivated for safety.
2) This warning function is not provided
when the driver selects the TCS-OFF
mode.

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.
C140A01A-AATDRIVING FOR ECONOMY
You can save fuel and get more miles from your
car if you follow these suggestions:
o Drive smoothly. Accelerate at a moderate
rate. Don't make "jack-rabbit" starts or full-
throttle shifts and maintain a steady cruising
speed. Don't race between stoplights. Try to
adjust your speed to that of the other traffic
so you don't have to change speeds unnec-
essarily. Avoid heavy traffic whenever pos-
sible. Always maintain a safe distance from
other vehicles so you can avoid unneces-
sary braking. This also reduces brake wear.
o Drive at a moderate speed. The faster you
drive, the more fuel your car uses. Driving at
a moderate speed, especially on the high-
way, is one of the most effective ways to
reduce fuel consumption.
o Don't "ride" the brake or clutch pedal. This
can increase fuel consumption and also
increase wear on these components. In
addition, driving with your foot resting on the
brake pedal may cause the brakes to over-heat, which reduces their effectiveness and
may lead to more serious consequences.
o Take care of your tires. Keep them inflated
to the recommended pressure. Incorrect
inflation, either too much or too little, results
in unnecessary tire wear. Check the tire
pressures at least once a month.
o Be sure that the wheels are aligned cor-
rectly. Improper alignment can result from
hitting curbs or driving too fast over irregular
surfaces. Poor alignment causes faster tire
wear and may also result in other problems
as well as greater fuel consumption.
o Keep your car in good condition. For better
fuel economy and reduced maintenance
costs, maintain your car in accordance with
the maintenance schedule in Section 5. If
you drive your car in severe conditions,
more frequent maintenance is required (see
Section 5 for details).
o Keep your car clean. For maximum service,
your Hyundai should be kept clean and free
of corrosive materials. It is especially impor-
tant that mud, dirt, ice, etc. not be allowed to
accumulate on the underside of the car. This
extra weight can result in increased fuel
consumption and also contribute to corro-
sion.
o Travel lightly. Don't carry unnecessary
weight in your car. Weight reduces fuel
economy.
o Don't let the engine idle longer than neces-
sary. If you are waiting (and not in traffic),
turn off your engine and restart only when
you're ready to go.o Remember, your Hyundai does not require
extended warm-up. As soon as the engine
is running smoothly, you can drive away. In
very cold weather, however, give your en-
gine a slightly longer warm-up period.
o Don't "lug" or "over-rev" the engine. Lugging
is driving too slowly in too high a gear result-
ing in the engine bucking. If this happens,
shift to a lower gear. Over-revving is racing
the engine beyond its safe limit. This can be
avoided by shifting at the recommended
speeds.
o Use your air conditioning sparingly. The air
conditioning system is operated by engine
power so your fuel economy is reduced
when you use it.
C160A01A-AATWINTER DRIVING
The 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:
C150A01A-AAT
SMOOTH CORNERING
Avoid 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.

2- 14 DRIVING YOUR HYUNDAI
C160G01A-AATTo Keep Locks from Freezing
To 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 burning the
fingers.
C160D01A-AAT
Check Battery and Cables
Winter 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.
C160F01A-AATCheck Spark Plugs and Ignition
System
Inspect 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
Necessary
In 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.
C160C01A-AATUse High Quality Ethylene Glycol
Coolant
Your 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.
C160B01A-AATSnowy or Icy Conditions
To 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.

C160J01A-AATDon't Let Ice and Snow Accumulate
Underneath
Under 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-AAT
Don't Let Your Parking Brake Freeze
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 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.
C160H01A-AATUse Approved Anti-Freeze in Window
Washer System
To keep the water in the window washer system
from freezing, add an approved anti-freeze
solution in accordance with instructions on the
container. Window washer anti-freeze is avail-
able from Hyundai dealers and most auto parts
outlets. Do not use engine coolant or other types
of anti-freeze as these may damage the finish.
C160K01A-AAT
Carry Emergency Equipment
Depending on the severity of the weather where
you drive your car, you should carry appropri-
ate emergency equipment. Some of the items
you may want to carry include tire chains, tow
straps or chains, flashlight, emergency flares,
sand, a shovel, jumper cables, a window scraper,
gloves, ground cloth, coveralls, a blanket, etc.
C170A01A-AATHIGHER SPEED MOTORING
Pre-Trip Inspections
1. Tires:
Adjust the tire inflation pressures to specifica-
tion. Low tire inflation pressures will result in
overheating and possible failure of the tires.
Avoid using worn or damaged tires which may
result in reduced traction or tire failure.
NOTE:Never exceed the maximum tire inflation
pressure shown on the tires.
2. Fuel, engine coolant and engine oil:
High speed travel consumes 1.5 times more
fuel than urban motoring. Do not forget to check
both engine coolant and engine oil.
3. Drive belt:
A loose or damaged drive belt may result in
overheating of the engine.
