FEATURES OF YOUR HYUNDAI 1- 53
The fuel-filler lid may be opened from inside the
vehicle by pulling up on the fuel-filler lid opener
located on the front floor area on the left side of
the car.
NOTE:If the fuel-filler lid will not open because ice
has formed around it, tap lightly or push on
the lid to break the ice and release the lid. Do
not pry on the lid. If necessary, spray around
the lid with an approved de-icer fluid (do not
use radiator anti-freeze) or move the vehicle
to a warm place and allow the ice to melt.
WARNING:o The fuel cap must be tightened at least 3
clicks, otherwise " " light will illumi-
nate.
o Gasoline vapors are dangerous. Before
refueling, always stop the engine and
never allow sparks or open flames near
the filler area. If you need to replace the
filler cap, use a genuine Hyundai replace-
ment part.
o If you open the fuel filler cap during high
ambient temperatures, a slight "pressure
sound" may be heard. This is normal and
not a cause for concern.
Whenever you open the fuel filler cap,
turn it slowly.
o Make sure the fuel filler cap is replaced
and securely seated after fueling. Failure
to replace or fully seat the fuel filler cap
will result in fuel vapors escaping into the
atmosphere and the check engine (MIL)
indicator " " illuminating.
o Do not "TOP-OFF" after the first nozzle
shut off when refueling.

3- 10 WHAT TO DO IN AN EMERGENCY
D060I01E-GAT8. Lower Vehicle and Tighten Nuts
Lower the car to the ground by turning the wheel
nut wrench 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
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. 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)
D060J01E-AATAfter Changing Wheels
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 replaced, 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 and tools to their proper storage locations.
D080A01A-AATIF YOUR CAR MUST BE TOWED
CAUTION:
Your car can be damaged if towed incor-
rectly!
HLC4008HLC4012
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 gen-
erally aware of state and local laws governing
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.

VEHICLE MAINTENANCE REQUIREMENTS 5- 7
F060D01A-AATo Fuel lines, fuel hoses and
connections
Check the fuel lines, fuel hoses and connec-
tions for leakage and damage. Have a trained
techincian, replace any damaged or leaking
parts immediately.
F060C01A-AAT
o Fuel filter
A clogged filter can limit the speed at which the
vehicle may be driven, damage the emission
system and cause hard starting. If an excessive
amount of foreign matter accumulates in the fuel
tank, the filter may require replacement more
frequently.
After installing a new filter, run the engine for
several minutes, and check for leaks at the
connections.
Fuel filters should be installed by trained techni-
cians.
F060M01A-AAT
o Engine oil and filter
The engine oil and filter should be changed at
the intervals specified in the maintenance sched-
ule. If the car is being driven in severe condi-
tions, more frequent oil and filter changes are
required.
F060A01A-AATEXPLANATION OF SCHEDULED MAIN-
TENANCE ITEMS
F060H01A-AATo Air cleaner filter
A Genuine Hyundai air cleaner filter is recom-
mended when the filter is replaced.
F060G01A-AATo Vapor hose and fuel filler cap
The vapor hose and fuel filler cap should be
inspected at those intervals specified in the
maintenance schedule. Make sure that a new
vapor hose or fuel filler cap is correctly re-
placed.
F060F01A-AAT
o Vacuum, crankcase ventilation
hoses
Inspect the surface of hoses for evidence of
heat and/or mechanical damage. Hard and brittle
rubber, cracking, tears, cuts, abrasions, and
excessive swelling indicate deterioration. Par-
ticular attention should be paid to examine those
hose surfaces nearest to high heat sources,
such as the exhaust manifold.
Inspect the hose routing to assure that the
hoses do not come in contact with any heat
source, sharp edges or moving component which
might cause heat damage or mechanical wear.
Inspect all hose connections, such as clamps
and couplings, to make sure they are secure,
and that no leaks are present. Hoses
should be replaced immediately if there is any
evidence of deterioration or damage.
F060B01A-AAT
o Drive belts
Inspect all drive belts for evidence of cuts,
cracks, excessive wear or oil saturation and
replace if necessary. Drive belts should be
checked periodically for proper tension and ad-
justed as necessary.
F060J01A-AAT
o Spark plugs
Make sure to install new spark plugs of the
correct heat range.

DO-IT-YOURSELF MAINTENANCE 6- 7
G050D02A-AATTo Change the Coolant
The coolant should be changed at those inter-
vals specified in the vehicle maintenance sched-
ule 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 parking
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 demineralized
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.
G050D01A
G050D02A
5. Start the engine, top off the radiator with
water and then add engine coolant to the
reservoir until the level is between "LOW"
and "FULL".
6. 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 operate
even when the engine is not running. Use
extreme caution when working near the
blades of the cooling fan so that you are not
injured by a rotating fan blade. As the engine
coolant temperature decreases, the fan will
automatically shut off. This is a normal con-
dition.

DO-IT-YOURSELF MAINTENANCE 6- 11
G100B02A-AATTo check the Manual Transaxle Fluid
Level
Park the car on level ground with the engine off.
1. Using a wrench of the correct size, loosen
the oil filler plug by turning it counterclock-
wise and remove it with your fingers.
WARNING:It is always better to check the transaxle oil
level when the engine is cool or cold. If the
engine is hot, you should exercise great
caution to avoid burning yourself on hot
engine or exhaust parts.

G100B01L
G110A01A-AAT
CHECKING THE TRANSAXLE FLUID
(AUTOMATIC)
Transaxle fluid in the automatic transaxle should
be checked at those intervals specified in the
vehicle maintenance schedule in Section 5.
G110B03A-AAT
Recommended Fluid
Your Hyundai automatic transaxle is specially
designed to operate with HYUNDAI GENUINE
ATF, DIAMOND ATF SP-III or SK ATF SP-III.
Damage caused by a nonspecified fluid is not
covered by your new vehicle limited warranty.
G110C02A-AATTransaxle Fluid Capacity
The fluid capacity of the automatic transaxle is
6.45 U.S. quarts (6.1 liters). 2. Use your finger or suitable tool to feel inside
the hole. The oil level should be at its bottom
edge. If it is not, check for leaks before
adding oil. To refill the transaxle or bring the
oil level up, add oil slowly until it reaches the
proper level. Do not overfill.
3. Replace the plug and washer, screw it in with
your fingers and then tighten securely with
the wrench.
WARNING:The transaxle fluid level should be checked
when the engine is at normal operating tem-
perature. This means that the engine, radia-
tor, exhaust system etc., are very hot. Exer-
cise great care not to burn yourself during
this procedure.
