GAUGE
WARNING:Never remove the radiator cap when the
engine is hot. The engine coolant is under
pressure and could erupt and cause
severe burns. Wait until the engine is
cool before adding coolant to the
reservoir.The normal range is approximately in the
middle between "H" and "C". If it moves
across the dial to "H" (HOT), pull over and
stop as soon as possible and turn off the
engine. Then open the hood and, after the
engine has cooled, check the coolant level
(See "If the engine overheats" on the page
3-4.) and the water pump drive belt. If you
suspect cooling system trouble, have your
cooling system checked by a Hyundai dealer
as soon as possible.

B740C02O-AATDe-Humidified HeatingFor dehumidified heating:
o Set the air flow control to the face ( )
position.
o Turn on the air conditioning switch. The
air conditioning indicator light should
come on at the same time.
o Set the air intake control to the fresh air
( ) position.
o Adjust the fan control to the desired
speed.
o For more rapid action, set the fan at one
of the higher speeds.
o Adjust the temperature control to provide
the desired amount of warmth.
B740D02Y-AATOperation Tipso If the interior of the car is hot when you
first get in, open the windows for a few
minutes to expel the hot air.
o When you are using the air conditioning
system, keep all windows closed to
keep hot air out.
o When moving slowly, as in heavy traffic,
shift to a lower gear. This increases
engine speed, which in turn increases
the speed of the air conditioning
compressor.
o On steep grades, turn the air condition-
ing off to avoid the possibility of the
engine overheating.
o During winter months or in periods when
the air conditioning is not used regularly,
run the air conditioning once every
month for a few minutes. This will help
circulate the lubricants and keep your
system in peak operating condition.

STARTING!
C050A01A-AAT
WARNING:
Never run the engine in a closed or poorly
ventilated area any longer than is needed
to move your car in or out of the area. The
carbon monoxide gas emitted is odorless
and can cause serious injury or death.
C050A01E
4. Turn the ignition key to the "START"
position and release it when the engine
starts.
After the engine has started, allow the
engine to run for 10 to 20 seconds prior
to placing the vehicle in gear.
The starter should not be operated for
more than 15 seconds at a time. Wait
15-30 seconds between starting
attempts to protect the starter from
overheating.
C050B02A-AATNormal Conditions:The Starting Procedure:
1. Insert key, and fasten the seat belt.
2. Depress the clutch pedal fully and place
the gearshift lever (manual transaxle)
in neutral or the selector lever (automatic
transaxle) in "P" (Park) position.
3. After turning the ignition key to the "ON"
position, make certain all warning lights
and gauges are functioning properly
before starting the engine.
WARNING:
Be sure that the clutch is fully depressed
when starting a manual transaxle vehicle.
Your manual transaxle equipped vehi-
cle will not start unless the clutch pedal
is fully depressed. On a manual transaxle
equipped vehicle that can be started
without depressing the clutch, there is
the potential to cause damage to the
vehicle or injury to someone inside or
outside the vehicle as a result of the
forward or backward movement of the
vehicle that will occur if the clutch is not
depressed when the vehicle is started.
!
WARNING:
Always fully depress the brake pedal
before and while shifting out of the "P"
Park position into another position to
avoid inadvertent motion of the vehicle
which could injure persons in or around
the car.

C070B02A-AATUsing the ClutchThe clutch should be pressed all the way
to the floor before shifting, then released
slowly. The clutch pedal should always be
fully released while driving. Do not rest
your foot on the clutch pedal while driving.
This can cause unnecessary wear. Do not
partially engage the clutch to hold the car
on an incline. This causes unnecessary
wear. Use the foot brake or parking brake
to hold the car on an incline. Do not operate
the clutch pedal rapidly and repeatedly.
WARNING:
o Always buckle-up! In a collision, an
unbelted occupant is significantly
more likely to be seriously injured or
killed than a properly belted occupant.
o Avoid high speeds when cornering or
turning.
o Do not make quick steering wheel
movements, such as sharp lane
changes or fast, sharp turns.
o The risk of rollover is greatly
increased if you lose control of your
vehicle at highway speeds.
o Loss of control often occurs if two or
more wheels drop off the roadway
and the driver oversteers to reenter
the roadway.
o In the event your vehicle leaves the
roadway, do not steer sharply. Instead,
slow down before pulling back into the
travel lanes.
o Never exceed posted speed limits.
C070D03O-AATGood Driving Practiceso Never take the car out of gear and coast
down a hill. This is extremely hazardous.
Always leave the car in gear.
o Don't "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. This will help avoid over-revving
the engine, which can cause damage.
o Slow down when you encounter cross
winds. This gives you much better control
of your car.
o Be sure the car is completely stopped
before you attempt to shift into reverse.
The transaxle can be damaged if you do
not. To shift into reverse, depress the
clutch, move the shift lever to neutral,
wait three seconds, then shift to the
reverse position.
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 vehicle speed can
cause the drive wheels to lose traction
and the vehicle to go out of control.

C090N05O-AATGood Driving Practiceso Never move the gear selector lever
from "P" or "N" to any other position with
the accelerator pedal depressed.
o Never move the gear selector lever into
"P" when the vehicle is in motion.
o Be sure the vehicle is completely
stopped before you attempt to shift into
"R" or "D".
o Never take the vehicle out of gear and
coast down a hill. This may be extremely
hazardous. Always leave the vehicle 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 engaged.
o Always use the parking brake. Do not
depend 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 vehicle speed can
cause the drive wheels to lose traction
and the vehicle to go out of control.
WARNING:
o Always buckle-up! In a collision, an
unbelted occupant is significantly
more likely to be seriously injured or
killed than a properly belted occupant.

roadway, do not steer sharply. Instead,
slow down before pulling back into the
travel lanes.
o Never exceed posted speed limits.
WARNING:
If your vehicle becomes stuck in snow,
mud, sand, etc., then you may attempt to
rock the vehicle free by moving it for-
ward and backward. Do not attempt this
procedure if people or objects are any-
where near the vehicle. During the rock-
ing operation the vehicle may suddenly
move forward or backward as it be-
comes unstuck, causing injury or
damage to nearby people or objects. o Optimum vehicle performance and
economy is obtained by smoothly de-
pressing and releasing the accelerator
pedal.

!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. Vehicles 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
parking brake fully engaged when
parking to avoid inadvertent
movement of the car which can injure
occupants or pedestrians.
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 occupants.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 components.
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.
Firmly 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.

o Travel lightly. Don't carry unnecessary
weight in your car. Weight reduces fuel
economy.
o Don't let the engine idle longer than
necessary. 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 re-
quire extended warm-up. After the en-
gine has started, allow the engine to run
for 10 to 20 seconds prior to placing the
vehicle in gear. In very cold weather,
however, give your engine 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 resulting 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. 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
correctly. 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 important 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 cor-
rosion.
DRIVING FOR ECONOMYC140A02A-AATYou 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 unneces-
sarily. Avoid heavy traffic whenever pos-
sible. Always maintain a safe distance
from other vehicles so you can avoid
unnecessary 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 highway, 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 overheat, which
reduces their effectiveness and may
lead to more serious consequences.

C160K01A-AATCarry Emergency EquipmentDepending on the severity of the weather
where you drive your car, you should carry
appropriate 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.
HIGHER SPEED MOTORINGC170A02A-AATPre-Trip Inspections1. Tires:
Adjust the tire inflation pressures to speci-
fication. 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 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.
WARNING:
o Underinflated or overinflated tires
can cause poor handling, loss of
vehicle control, and sudden tire failure
leading to accidents, injuries, and
even death. Always check tires are
properly inflated before driving. Refer
to pages 2-23 and 8-3 for proper tire
pressures and further information.
o Driving on tires with no or insufficient
tread is dangerous. Worn-out tires
can result in loss of vehicle control,
collisions, injury, and even death.
Worn-out tires should be replaced as
soon as possible and should never be
used for driving. Always check tire
tread before driving your car. Refer
to 8-10 for further information and
tread limits.

C190D01S-AATSafety ChainsShould the hitch connection between your
car and the trailer or vehicle you are towing
fail, the trailer or vehicle could wander
dangerously across other lanes of traffic
and ultimately leave the roadway. To
eliminate this potentially dangerous
situation, safety chains, attached between
your car and the trailer or towed vehicle,
are required in most states.
CAUTION:
o Never connect a trailer brake system
directly to the vehicle brake system.
o When towing a trailer on steep grades
(in excess of 6%) pay close attention
to the engine coolant temperature
gauge to ensure the engine does not
overheat. If the needle of the coolant
temperature gauge moves across the
dial towards "H" (HOT), pull over and
stop as soon as it is safe to do so, and
allow the engine to idle until it cools
down. You may proceed once the
engine has cooled sufficiently.
