DRIVING YOUR HYUNDAI
2- 11 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
resulting in the engine bucking. If this hap-
pens, shift to a lower gear. Over-revving is
racing the engine beyond its safe limit. This
can be avoided by shifting at the recom-
mended 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.
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.
C160A01A-AAT
WINTER 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: o Take care of your tires. Keep them inflated
to the recommended pressure. Incorrect in-
flation, either too much or too little, results in
unnecessary tire wear. Check the tire pres-
sures at least once a month.
o Be sure that the wheels are aligned correct-
ly. Improper alignment can result from hitting
curbs or driving too fast over irregular sur-
faces. 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.
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-
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 to the original equipment tires. Failure
to do so may adversely affect the safety and
handling of your car. Speeding, rapid accelera-
tion, 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 front and your vehicle. Also, apply
the brake gently. It should be noted that install-
ing 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.

WHAT TO DO IN AN EMERGENCY
3-2 to follow this procedure, seek qualified as-
sistance. Automobile batteries contain sul-
furic acid. This is poisonous and highly
corrosive. When jump starting, wear protec-
tive glasses and be careful not to get acid on
yourself, your clothing or on the car.
o If you should accidentally get acid on your
skin or in your eyes, immediately remove
any contaminated clothing and flush the
area with clear water for at least 15 minutes.
Then promptly obtain medical attention. If
you must be transported to an emergency
facility, continue to apply water to the affect-
ed area with a sponge or cloth.
o The gas produced by the battery during the
jump-start operation is highly explosive. Do
not smoke or allow a spark or an open flame
in the vicinity.
o The battery being used to provide the jump
start must be 12-volt. If you cannot deter-
mine that it is a 12-volt battery, do not
attempt to use it for the jump start.
o To jump start a car with a discharged bat-
tery, follow this procedure exactly:
1. If the booster battery is installed in another
vehicle, be sure the two vehicles are not
touching.
2. Turn off all unnecessary lights and acces-
sories in both vehicles.
3. Attach the clamps of the jumper cable in the
exact location shown on the previous page.
First, attach one clamp of the jumper cableto the positive (+) post or cable of the dis-
charged battery. Then attach the other end
of the same cable to the positive (+) post or
cable of the booster battery. Next, using the
other cable, attach one clamp to the nega-
tive (-) post or cable of the booster battery.
Then attach the other end of that cable to a
solid metal part of the engine away from the
battery. Do not connect the cable to any
moving part.
4. Start the engine in the car with the booster
battery and let it run for a few minutes. This
will help to assure that the booster battery is
fully charged. During the jumping operation,
run the engine in this vehicle at about 2,000
rpm.
5. Start your engine using the normal starting
procedure. After the engine starts, leave the
jumper cables connected and let the engine
run at fast idle or about 2,000 rpm for sev-
eral minutes.
6. Carefully remove the jumper cables in the
reverse order of attachment.
If you do not know why your battery became
discharged (because the lights were left on,
etc.), have the charging system checked by your
Hyundai dealer.
D030A01A-AATIF THE ENGINE OVERHEATS
If your temperature gauge indicates overheating,
you experience a loss of power, or hear loud
pinging or knocking and the engine is probably
too hot. If this happens and, you should:
1. Pull off the road and stop as soon as it is
safe to do so.
2. Place the gear selector lever in "P" (auto-
matic), or neutral (manual transaxle) and set
the parking brake. If the air conditioning is
on, turn it off.
3. If engine coolant is running out under the car
or steam is coming out from the hood, stop
the engine. Do not open the hood until the
engine coolant has stopped running or the
steaming has stopped. If there is no visible
loss of engine coolant and no steam, leave
the engine running and check to be sure the
engine cooling fan is operating. If the fan is
not running, turn the engine off.
4. Check to see if the water pump drive belt is
missing. If it is not missing, check to see that
it is tight. If the drive belt seems to be
satisfactory, check for engine coolant leak-
ing from the radiator, hoses or under the car.
(If the air conditioning had been in use, it is
normal for cold water to be draining from it
when you stop).

WHAT TO DO IN AN EMERGENCY
3-3
WARNING:While the engine is running, keep hair, hands,
and clothing away from moving parts such
as the fan and drive belts to prevent injury.
5. If the water pump drive belt is broken or
engine coolant is leaking out, stop the en-
gine 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 serious
burns.
6. If you cannot find the cause of the overheat-
ing, wait until the engine temperature has
returned to normal. Then, if the engine cool-
ant has been lost, carefully remove the ra-
diator cap and add engine 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 hap-
pens again, call a Hyundai dealer for assis-
tance.
CAUTION:Serious loss of engine coolant indicates
there is a leak in the cooling system and this
should be checked as soon as possible by a
Hyundai dealer.

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 80 km/h
(50 mph) is not recommended.
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

with a wrench of the proper size. Be sure
that a drain pan is in position to catch the oil
as it drains out, then remove the drain plug.
WARNING:Be very careful when draining the engine oil
as it may be hot enough to burn you!
4. When the oil has stopped draining, replace
the drain plug using a new washer and
retighten by turning it clockwise.
Tightening torque is:
4.5 ~ 4.0 kgf.m (2.0L)
4.5 ~ 3.5 kgf.m (2.7L)
5. Remove the oil filter by turning it counter-
clockwise with a oil filter wrench of the
proper size. A certain amount of oil will
come out when you remove the filter. So be
sure to have your drain pan in place under-
neath it.
6. Install a new oil filter in accordance with the
instructions on the carton or on the filter
itself. Do not over-tighten. (Tightening
torque : 1.2 ~ 1.6 kgf.m)
Be sure that the mounting surface on the
engine is clean and that the old gasket is
removed completely. Lubricate the new gas-
ket on the filter with clean engine oil before
installation.
7. Refill the crankcase with the recommended
engine oil. Refer to the specification in chap-
ter 9 for engine oil capacity.8. Start the engine and check to be sure no oil
is leaking from the drain plug or oil filter.
9. Shut off the engine and recheck the oil level.
NOTE:Always dispose of used engine oil in an
environmentally acceptable manner. It is sug-
gested that it be placed in a sealed container
and taken to a service station for reclama-
tion. Do not pour the oil on the ground or
put it into the household trash.
WARNING:Used motor oil may cause irritation or can-
cer of the skin if left in contact with the skin
for prolonged periods of time. Wash your
hands thoroughly with soap and warm wa-
ter as soon as possible after handling used
oil.
G050A01A-AATCHECKING AND CHANGING THE EN-
GINE COOLANT
WARNING:
Do not remove the radiator cap when the
engine is hot. When the engine is hot, the
engine coolant is under pressure and may
erupt through the opening if the cap is
removed. You could be seriously burned if
you do not observe this precaution. Do not
remove the radiator cap until the radiator is
cool to the touch.
G050B01A-AATRecommended Engine Coolant
Use a high quality ethylene-glycol coolant in a
50/50 mix with water. The engine coolant should
be compatible with aluminum engine parts.
Additional corrosion inhibitors or additives should
not be used. The cooling system must be main-
tained with the correct concentration and type
of engine coolant to prevent freezing and corro-
sion. Never allow the concentration of anti-
freeze to exceed the 60% level or go below the
35% level, or damage to the cooling system
may result. For proper concentration when add-
ing or replacing the engine coolant, refer to the
following table.

To Check the Coolant Level
The coolant level can be seen on the side of the
plastic coolant reservoir. The level of the cool-
ant should be between the "LOW" and "FULL"
lines on the reservoir when the engine is cold.
If the level is below the "LOW" mark, add
engine coolant to bring it up between "LOW"
and "FULL". If the level is low, inspect for
coolant leaks and recheck the fluid level fre-
quently. If the level drops again, visit your
Hyundai dealer for an inspection and diagnosis
of the reason.
G050D02A-AATTo Change the Engine Coolant
The engine coolant should be changed at those
intervals specified in the vehicle maintenance
schedule in Section 5.
CAUTION:Engine coolant can damage the finish of
your car. If you spill engine coolant on the
car, wash it off thoroughly with clean water.
1. Park the car on level ground, set the park-
ing brake and remove the radiator cap when
cool.
2. Be sure your drain receptacle is in place.
Open the drain cock on the radiator. Allow
all the engine coolant to drain from the
cooling system, then securely close the drain
cock.
3. Check Section 9 for the capacity of the
cooling system in your car. Then, following
the manufacturer’s directions on the engine
coolant container, add the appropriate quan-
tity of coolant to the radiator.
4. Turn the radiator cap counterclockwise with-
out pressing down on it, until it stops. This
relieves any pressure remaining in the cool-
ing system. And remove the radiator cap by
pushing down and turning counterclockwise.
Now fill the radiator with clean demineral-
ized or distilled water. Continue to add clean
demineralized or distilled water in small quan-
tities until the fluid level stays up in the
radiator neck.5. Replace the radiator and reservoir caps and
check to be sure the drain cocks are fully
closed and not leaking.
WARNING:The cooling fan is controlled by engine cool-
ant temperature and may sometimes oper-
ate even when the engine is not running.
Use extreme caution when working near the
blades of the coolant fan so that you are not
injured by a rotating fan blade. As the en-
gine coolant temperature decreases, the fan
will automatically shut off. This is a normal
condition.

DOT 3 or DOT 4 specifications in your braking
system. Follow the instructions printed on the
container.
G120D01A-AAT
To Check the Fluid LevelThe fluid level in the brake fluid reservoir should
be checked periodically. The level should be
between the "MIN" and "MAX" marks on the
side of the reservoir. If the level is at or below
the "MIN" mark, carefully add fluid to bring it up
to "MAX". Do not overfill.

Adding Brake FluidWARNING:
Handle brake fluid carefully. It can damage
your vision if it gets into your eyes. Use only
DOT 3 or DOT 4 specification fluid from a
sealed container. Do not allow the fluid can
or reservoir to remain open any longer than
required. This will prevent entry of dirt and
moisture which can damage the brake sys-
tem and cause improper operation.
To add brake fluid, first wipe away any dirt then
unscrew the fluid reservoir cap. Slowly pour the
recommended fluid into the reservoir. Do not
overfill. Carefully replace the cap on the reser-
voir and tighten.

1. Start the engine and let it run at a fast idle for
several minutes with the air conditioning set
at the maximum cold setting.
2. If the air coming out of the in-dash vents is
not cold, have the air conditioning system
inspected by your Hyundai dealer.
CAUTION:Running the air conditioning system for
extended periods of time with a low refriger-
ant level may damage the compressor.
G140C01A-AAT
LubricationTo lubricate the compressor and the seals in
the system, the air conditioning should be run
