After 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 thenearest service station and inflate to the correctpressure. If it is too high, adjust it until it iscorrect. Always reinstall the valve cap afterchecking or adjusting tire pressure. If the cap isnot replaced, air may leak from the tire. If youlose a valve cap, buy another and install it assoon as possible.
After you have changed wheels, always secure
the flat tire in its place in the luggage room andreturn the jack and tools to their proper storagelocations. D080A01A-GAT
IF YOUR CAR MUST BE TOWED D080B01A-AAT
Towing a Car With a Manual Transaxle
o OK FOR AUTOMATIC OR MANUAL TRANSAXLE EQUIPPED VEHICLE WITH NO DAMAGE
o OK FOR AUTOMATIC OR MANUAL
TRANSAXLE EQUIPPED VEHICLE
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 truckservice. This will help assure that your car isnot damaged in towing. Also, professionals aregenerally aware of state and local laws govern-ing towing. In any case, rather than risk dam-age to your car, it is suggested that you showthis information to the tow truck operator. Besure that a safety chain system is used and thatlocal laws are observed. o If the car is being towed with the rear wheels
on the ground, be sure the parking brake isreleased.
o If the car is being towed with the front wheels on the ground, be sure that thetransaxle is in neutral. Also, be sure that theignition key is in the "ACC" position. This isnecessary to prevent damage to the steer-ing lock mechanism, which is not designedto hold the front wheels straight while the caris being towed.
o If any of the loaded wheels or suspension components are damaged, a towing dollymust be used.

VEHICLE MAINTENANCE REQUIREMENTS 5-5
F060A01A-AAT
EXPLANATION OF SCHEDULED MAIN- TENANCE ITEMS
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 arerequired.
F060B01A-AAT
o Drive belts
Inspect all drive belts for evidence of cuts,
cracks, excessive wear or oil and replace ifnecessary. Drive belts should be checked pe-
riodically for proper tension and adjusted asnecessary.
F060C01A-GAT
o Fuel filter
A clogged filter can limit the speed at which the
vehicle may be driven, damage the emissionsystem and cause hard starting. If an exces-sive amount of foreign matter accumulates inthe fuel tank, the filter may require replacementmore frequently.
After installing a new filter, run the engine for
several minutes, and check for leaks at theconnections. F060D01A-GAT
o Fuel lines, fuel hoses and connec-
tions
Check the fuel lines, fuel hoses and connec-
tions for leakage and damage. Replace anydamaged or leaking parts immediately. Inspect the hose routing to assure that the
hoses do not come in contact with any heatsource, sharp edges or moving component
which might cause heat damage or mechanicalwear. Inspect all hose connections, such as
clamps and couplings, to make sure they aresecure, and that no leaks are present. Hoses
should be replaced immediately if there is any
evidence of deterioration or damage.
F060H01A-AAT
o Air cleaner filter
A Genuine Hyundai air cleaner filter is recom-
mended when filter is replaced.
F060J01A-AAT
o Spark plugs
Make sure to install new spark plugs of the
correct heat range.
F060E01A-AAT
o Timing belt Inspect all parts related to the timing belt for
damage and deformation. Replace any dam-aged parts immediately.
F060G01A-AAT
o Vapor hose and fuel filler cap The vapor hose and fuel filler cap should be
inspected at those intervals specified in themaintenance schedule. Make sure that a newvapor hose or fuel filler cap is correctly re-placed.
F060F01A-AAT
o Vacuum, crankcase ventilation hos-
es
Inspect the surface of hoses for evidence of
heat and/or mechanical damage. Hard and brit-tle rubber, cracking, tears, cuts, abrasions, and
excessive swelling indicate deterioration. Par-ticular attention should be paid to examinethose hose surfaces nearest to high heat sourc-es, such as the exhaust manifold. F060N01X-GAT
o Valve clearances Incorrect valve clearance will not only result in
unsteady engine operation, but will also causeexcessive noise and reduced engine perfor-
mance. Inspect valve clearance and adjust asrequired while the engine is hot.
Valve-to-rocker arm clearance Intake valves ..... 0.2 mm (0.008 in.)Exhaust valves .... 0.25 mm (0.010 in.)

Recommended 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. Ad-ditional corrosion inhibitors or additives shouldnot be used. The cooling system must be main-tained with the correct concentration and typeof engine coolant to prevent freezing and corro-sion. Never allow the concentration of antifreeze to exceed the 60% level or go below the 35% levelor damage to the coolant system may result. Forproper concentration when adding or replacingthe coolant, refer to the following table.
35% 40%50%60% G050C01A-AAT
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, addengine coolant to bring it up between "LOW"and "FULL". If the level is low, inspect forcoolant leaks and recheck the fluid level fre-quently. If the level drops again, visit yourHyundai dealer for an inspection and diagnosisof the reason. G050D02A-AAT
To Change the Engine Coolant
The engine coolant should be changed at thoseintervals specified in the vehicle maintenanceschedule in Section 5. CAUTION: Engine coolant can damage the finish of your car. If you spill engine coolant on thecar, wash it off thoroughly with clean water.
1. Park the car on level ground, set the parking brake and remove the radiator cap whencool.
2. Be sure your drain receptacle is in place. Open the drain cock on the radiator. Allowall the engine coolant to drain from thecooling system, then securely close the draincock.
3. Check Section 9 for the capacity of the cooling system in your car. Then, followingthe manufacturer's directions on the enginecoolant container, add the appropriate quan-tity of engine coolant to the radiator.

CHECKING THE TRANSAXLE FLUID (AUTOMATIC)
Transaxle fluid in the automatic transaxle should be checked at those intervals specified in thevehicle maintenance schedule in Section 5. G110B01X-AAT Recommended Fluid Your Hyundai automatic transaxle is specially designed to operate with ESSO JWS3314. Dam-age caused by a nonspecified fluid is not cov-ered by your new vehicle limited warranty. G110C01X-GAT
Transaxle Fluid Capacity The fluid capacity of the automatic transaxle is
5.2 liters (5.48 U.S. quarts). 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 duringthis procedure.
G100A04X-GAT CHECKING THE TRANSAXLE OIL (MANUAL) Transaxle lubricant in the manual and transaxle should be checked at those intervals specified in the vehicle maintenance schedule in Section5. Recommended Oil Use only HYUNDAI GENUINE PARTS MTF 75W/90 (API GL-4) in the manual transaxle. Manual Transaxle Oil Capacity The oil capacity of the manual transaxle is 2.45 liters (2.58 U.S. quarts). WARNING: It is always better to check the transaxle oil level when the engine is cool or cold. If theengine is hot, you should exercise greatcaution to avoid burning yourself on hotengine or exhaust parts. G100B01A-AAT
To check the Manual Transaxle Fluid Level
SSA6100B
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.
2. Use your finger or suitable tool to feel inside the hole. The oil level should be at its bottomedge. If it is not, check for leaks beforeadding oil. To refill the transaxle or bring theoil level up, add oil slowly until it reaches theproper level. Do not overfill.
3. Replace the plug and washer, screw it in with your fingers and then tighten securelywith the wrench.
