H020A01A-GAT
(If Installed) ; For a gasoline engine
HFC505
The catalytic converter is part of the
exhaust emission control system. Its purpose is to remove certain engine emission products from the engine'sexhaust. It looks something like a muffler and is located underneath the car in the exhaust system.
Catalytic Converter H020B01A-GAT
About the Catalytic Converter
Exhaust gases passing through the
catalytic converter cause it to operate at very high temperatures. As a re- sult, the introduction of large amounts of unburned gasoline may cause it tooverheat and create a fire hazard. This can be avoided by observing the following:
o Use unleaded fuel only.
o Maintain your engine in good con- dition. Extremely high converter temperatures can result from im-proper operation of the electrical, ignition or fuel injection systems. o If your engine stalls, pings, knocks,
or is hard to start, take your car to your Hyundai dealer as soon as possible and have the difficulty corrected.
o Avoid driving with a very low fuel level. If your run out of gasoline, itcould cause the engine to misfireand result in excessive loading of the catalytic converter.
o Avoid idling the engine for periods longer than 10 minutes.
o Your Hyundai should not be either pushed or pulled to get it started.This can cause the catalytic con- verter to overload.
o Take care not to stop your Hyundai
over any combustible material suchas grass, paper, leaves or rags. As these materials could come in con- tact with the catalytic converter andcould cause a fire.
o Do not touch the catalytic con-
verter or any other part of the ex-haust system while the engine is running as it is very hot and could result in burns.
o Remember that your Hyundai
dealer is your best source of assis-tance.
H020D01S-GAT
; For a diesel engine
All Hyundai vehicles are equipped
with oxidation type catalytic converter to reduce the carbon monoxide, hy- drocarbons and particulate containedin the exhaust gas.

I020A01A-AAT TIRE INFORMATION The tires supplied on your new Hyundai are chosen to provide the best performance for normal driving. I030A01FC-GAT RECOMMENDED INFLATION PRESSURES
The tire label located on the driver's
side "C" pillar outer panel gives the tire pressures recommended for your vehicle. These pressures were chosen to pro-
vide the most satisfactory combina-tion of ride comfort, tire wear andstability under normal conditions. Tire pressures should be checked at least monthly. Proper tire inflation pres-sures should be maintained for these reasons:
o Lower-than-recommended tire
pressures cause uneven tread wear and poor handling.
o Higher-than-recommended tire pressures increase the chance of damage from impacts and cause uneven tread wear.

I050A01E-GAT TIRE CHAINS Tire chains, if necessary should be installed on the front wheels. Be sure that the chains are installed in accor- dance with the manufacturer's instruc-tions.To minimize tire and chain wear, donot continue to use tire chains when they are no longer needed.
WARNING:
o When driving on roads covered with snow or ice, drive at less than 30 km/h (20 mph).
o Use the SAE "S" class or wire &
plastic chains.
o If you have noise caused by chains contacting the body, re-tighten the chain to avoid con- tact with the vehicle body.
o To prevent body damage, re- tighten the chains after driving0.5 ~ 1 km.
I040A01S-GAT SNOW TIRES If you equip your car with snow tires, they should be the same size and have the same load capacity as the original tires. Snow tires should beinstalled on all four wheels; other- wise, poor handling may result. Snow tires should carry 28 kPa (4 psi) more air pressure than the pres- sure recommended for the standardtires on the tire label on, or up to the maximum pressure shown on the tire sidewall whichever is less. Do not drive faster than 120 km/h (75 mph) when your car is equipped with snow tires.
CAUTION:
Always observe the following:
o Check pressures when the tires are cold. That is, after the car has been parked for at least three hours and hasn't been drivenmore than 1.6 km or one mile since starting up.
o Check the pressure of your spare tire each time you check the pressure of other tires.
o Never overload your car. Be es- pecially careful about overload-ing if you equip your car with a luggage rack or car top carrier.

TIRE ROTATION
Tires should be rotated every 10,000 km (6,000 miles). If you notice that tires are wearing unevenly between rotations, have the car checked by aHyundai dealer so the cause may be corrected. After rotating, adjust the tire pres- sures and be sure to check wheel nut torque. HA1409
Spare tireWARNING:
o Do not use the temporary spare tire for tire rotation.
o Do not mix bias-ply and radial- ply tires under any circum- stances. This may cause dan- gerous handling characteristics. I070A01A-AAT TIRE BALANCING A tire that is out of balance may affect handling and tire wear. The tires on your Hyundai were balanced before the car was delivered but may needbalancing again during the years you own the car. Whenever a tire is dismounted for repair, it should be rebalanced before being reinstalled on the car. I080A01A-AAT
TIRE TRACTION
Tire traction can be reduced if you
drive on worn tires, tires that are improperly inflated or on slippery road surfaces. Tires should be replaced when tread wear indicators appear.To reduce the possibility of losing control, slow down whenever there is rain, snow or ice on the road.

!WARNING:
o Driving on worn-out tires is dan- gerous! Worn-out tires can cause loss of braking effectiveness,steering control and traction. When replacing tires, never mix radial and bias-ply tires on thesame car. If you replace radial tires with bias-ply tires, they must be installed in sets of four.
o Your vehicle is equipped with tires designed to provide for saferide and handling capability.Do not use a size and type of tireand wheel that is different from the one that is originally installed on your vehicle. It can affect thesafety and performance of your vehicle, which could lead to han- dling failure or rollover and seri-ous injury.When replacing the tires, be sureto equip all four tires with the tireand wheel of the same size, type, tread, brand and load-carrying ca- pacity.
I090A01HP-GAT WHEN TO REPLACE TIRES
1.6 mm (0.06 in.)
The original tires on your car have tread wear indicators. The tread wear indicators appear when the tread depth is 1.6 mm (0.06 in.). The tireshould be replaced when these ap- pear as a solid bar across two or more grooves of the tread. Alwaysreplace your tires with those of the recommended size. If you change wheels, the new wheel's rim widthand offset must meet Hyundai speci- fication. Wear indicator
I090A02FC
If you nevertheless decide to equip your vehicle with any tire/wheel combination not recom- mended by Hyundai for off-road driving, you should not use thesetires for highway driving.
