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.

DRIVING YOUR HYUNDAI 2- 15
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.

2- 18 DRIVING YOUR HYUNDAI
CAUTION:If overheating should occur when towing,
(the temperature gauge reads near red zone),
taking the following action may reduce or
eliminate the problem.
1. Turn off the air conditioner.
2. Reduce highway speed.
3. Select a lower gear when going uphill.
4. While in stop and go traffic, place the gear
selector in park or neutral and idle the engine
at a higher speed.

C190F01S-AATTrailer or Vehicle Towing Tips
1. Before towing, check hitch and safety chain
connections as well as proper operation of
the trailer running lights, brake lights, and
turn signals.
2. Always drive your vehicle at a moderate
speed (Less than 60 mph)
3. Trailer towing requires more fuel than normal
conditions.
4. To maintain engine braking efficiency and
electrical charging performance, do not use
fifth gear (manual transaxle) or overdrive
(automatic transaxle).
5. Always secure items in the trailer to prevent
load shift while driving.
6. Check the condition and air pressure of all
tires on the trailer and your car. Low tire
pressure can seriously affect the handling.
Also check the spare tire.
7. The vehicle/trailer combination is more af-
fected by crosswind and buffeting.
When being passed by a large vehicle, keep
a constant speed and steer straight ahead.
If there is too much wind buffeting slow down
to get out of the other vehicle's air turbulence.
8. When parking your car and trailer, especially
on a hill, be sure to follow all the normal
precautions. Turn your front wheel into the
curb, set the parking brake firmly, and put the
transaxle in 1st or Reverse (manual) or Park
(automatic). In addition, place wheel chocks
at each of the trailer's tires.9. If the trailer has electric brakes, start your
vehicle and trailer moving, and then apply the
trailer brake controller by hand to be sure the
brakes are working. This lets you check
your electrical connection at the same time.
10.During your trip, check occasionally to be
sure that the load is secure, and that the
lights and any trailer brakes are still working.
11.Avoid jerky starts, sudden acceleration or
sudden stops.
12.Avoid sharp turns and rapid lane changes.
13.Avoid holding the brake pedal down too long
or too frequently. This could cause the brakes
to overheat, resulting in reduced braking
efficiency.
14.When going down a hill, shift into a lower gear
and use the engine braking effect.
When ascending a long grade, downshift the
transaxle to a lower gear and reduce speed
to reduce chances of engine overloading
and/or overheating.
15.If you have to stop while going uphill, do not
hold the vehicle in place by pressing on the
accelerator. This can cause the automatic
transaxle to overheat. Use the parking brake
or footbrake.
NOTE:When towing check transaxle fluid more
frequently.

D040A01Y-AATSPARE TIRE
The following instructions for the temporary
spare tire should be observed:
1. Check inflation pressure as soon as practi-
cal after installing the spare tire, and adjust
to the specified pressure. The tire pressure
should be periodically checked and main-
tained at the specified pressure while the tire
is stored.
Tire Size
Inflation Pressure
T125/80R15
60 psi (420 kPa) 5. If the water pump drive belt is broken or
engine coolant is leaking out, stop the engine
immediately and call the nearest Hyundai
dealer for assistance.
WARNING:Do not remove the radiator cap when the
engine is hot. This can allow coolant to be
blown out of the opening and cause seri-
ous burns.
6. If you cannot find the cause of the overheat-
ing, wait until the engine temperature has
returned to normal. Then, if coolant has been
lost, carefully remove the radiator cap and
add coolant to bring the fluid level in the
reservoir up to the halfway mark.
7. Proceed with caution, keeping alert for fur-
ther signs of overheating. If overheating
happens again, call a Hyundai dealer for
assistance.
CAUTION:Serious loss of coolant indicates there is a
leak in the cooling system and this should
be checked as soon as possible by a Hyundai
dealer.
!
4. As the temporary spare tire is specifically
designed for your car, it should not be used
on any other vehicle.
5. The temporary spare tire should not be used
on any other wheels, nor should standard
tires, snow tires, wheel covers or trim rings
be used with the temporary spare wheel. If
such use is attempted, damage to these
items or other car components may occur.
6. The temporary spare tire pressure should
be checked once a month while the tire is
stored.
Spare Tire Pressure
2. The spare tire should only be used tempo-
rarily and should be returned to the luggage
compartment as soon as the original tire can
be repaired or replaced.
3. Continuous use at speeds of over 50 mph
(80 km/h) is not recommended.
CAUTION:o Do not use snow chains with your tem-
porary spare tire.
o Do not use more than one temporary
spare tire at a time.

D060D02A-AAT3. Loosen Wheel NutsD060E01A-AAT4. Put the Jack in Place
The wheel nuts should be loosened slightly
before raising the car. To loosen the nuts, turn
the wrench handle counterclockwise. When
doing this, be sure that the socket is seated
completely over the nut so it cannot slip off. For
maximum leverage, position the wrench so the
handle is to the left as shown in the drawing.
Then, while holding the wrench near the end of
the handle, push down on it with steady pres-
sure. Do not remove the nuts at this time. Just
loosen them about one-half turn.The base of the jack should be placed on firm,
level ground. The jack should be positioned as
shown in the drawing.
D060F02E-AAT5. Raising the Car
After inserting a bar into the wheel nut wrench,
install the bar into the jack as shown in the
drawing. To raise the vehicle, turn the wheel nut
wrench clockwise. As the jack begins to raise
the vehicle, double check that it is properly
positioned and will not slip. If the jack is on soft
ground or sand, place a board, brick, flat stone
or other object under the base of the jack to keep
it from sinking.
Raise the car high enough so that the fully
inflated spare tire can be installed. To do this,
you will need more ground clearance than is
required to remove the flat tire.

WARNING:Do not get under the car when it is sup-
ported by the jack! This is very dangerous
as the vehicle could fall and cause serious
injury or death. No one should stay in the
car while the jack is being used.
D060G02Y-AAT6. Changing Wheels
D060H02A-AAT7. Reinstall Wheel Nuts
Loosen the wheel nuts and remove them with
your fingers. Slide the wheel off the studs and
lay it flat so it cannot roll away. To put the wheel
on the hub, pick up the spare tire, line up the
holes with the studs and slide the wheel onto
them. If this is difficult, tip the wheel slightly and
get the top hole in the wheel lined up with the top
stud. Then jiggle the wheel back and forth until
the wheel can be slid over the other studs.
WARNING:Wheels and wheel covers may have sharp
edges. Handle them carefully to avoid pos-
sible severe injury. Before putting the wheel
into place, be sure that there is nothing on
the hub or wheel (such as mud, tar, gravel,
etc.) that interferes with the wheel from
fitting solidly against the hub. If there is,
remove it. If there is not good contact on the
mounting surface between the wheel and
hub, the wheel nuts could come loose and
cause the loss of a wheel. Loss of a wheel
may result in loss of control of the vehicle.
This may cause serious injury or death.To reinstall the wheel, hold it on the studs, put
the wheel nuts on the studs and tighten them
finger tight. The nuts should be installed with
their small diameter ends directed inward. Jiggle
the tire to be sure it is completely seated, then
tighten the nuts as much as possible with your
fingers again.

D080A01A-AATIF YOUR CAR MUST BE TOWEDD060I01Y-AAT8. Lower Vehicle and Tighten NutsD060J01A-AATAfter Changing Wheels
Lower the car to the ground by turning the jack
handle counterclockwise. Then position the
wrench as shown in the drawing and tighten the
wheel nuts. Be sure the socket is seated com-
pletely over the nut. Do not stand on the wrench
handle or use an extension pipe over the wrench
handle.
Go around the wheel tightening every other nut
until they are all tight. Then double-check each
nut for tightness and reinstall the wheel cover.
After changing wheels, have a technician tighten
the wheel nuts to their proper torque as soon as
possible.
Wheel nut tightening torque:Steel wheel & aluminium alloy wheel:
65-80 lb.ft (900-1,100 kg.cm)If you have a tire gauge, remove the valve cap
and check the air pressure. If the pressure is
lower than recommended, drive slowly to the
nearest service station and inflate to the correct
pressure. If it is too high, adjust it until it is correct.
Always reinstall the valve cap after checking or
adjusting tire pressure. If the cap is not re-
placed, air may leak from the tire. If you lose a
valve cap, buy another and install it as soon as
possible.
After you have changed wheels, always secure
the flat tire in its place in the trunk and return the
jack, jack handle, and tools to their proper
storage locations.
CAUTION:Your car can be damaged if towed incor-
rectly!
If your car has to be towed, it should be done by
your Hyundai dealer or a commercial tow truck
service. This will help assure that your car is not
damaged in towing. Also, professionals are
generally aware of state and local laws govern-
ing towing. In any case, rather than risk damage
to your car, it is suggested that you show this
information to the tow truck operator. Be sure
that a safety chain system is used and that all
state and local laws are observed.
