B740D01Y-AAT Operation Tips
o If the interior of the car is hot when
you first get in, open the windows for a few minutes to expel the hot air.
o When you are using the air condi-
tioning system, keep all windowsclosed to keep hot air out.
o When moving slowly, as in heavy
traffic, shift to a lower gear. Thisincreases engine speed, which in turn increases the speed of the air conditioning compressor.
o On steep grades, turn the air condi- tioning off to avoid the possibility ofthe engine overheating.
o During winter months or in periods when the air conditioning is not usedregularly, run the air conditioningonce every month for a few min- utes. This will help circulate the lubricants and keep your system inpeak operating condition.

C070D02O-AAT Good Driving Practices
o Never take the car out of gear and
coast down a hill. This is extremely hazardous. Always leave the car in gear.
o Don't "ride" the brakes. This can
cause them to overheat and mal-function. Instead, when you are driv- ing down a long hill, slow down andshift to a lower gear. When you do this, engine braking will help slow the car.
o Slow down before shifting to a lower gear. This will help avoid over-rev-ving the engine, which can causedamage.
o Slow down when you encounter
cross winds. This gives you muchbetter control of your car.
o Be sure the car is completely stopped
before you attempt to shift into re-verse. The transaxle can be dam- aged if you do not. To shift into reverse, depress the clutch, movethe shift lever to neutral, wait three seconds, then shift to the reverse position.
o Exercise extreme caution when driv- ing on a slippery surface. Be espe-cially careful when braking, acceler-
C070B01A-AAT Using the Clutch The clutch should be pressed all the way to the floor before shifting, then released slowly. The clutch pedal should always be used after fully re-turning to the original position. Do not rest your foot on the clutch pedal while driving. This can cause unnecessarywear. Do not partially engage the clutch to hold the car on an incline. This causes unnecessary wear. Use theparking brake to hold the car on an incline. Do not operate the clutch pedal rapidly and repeatedly. CAUTION:
When downshifting from fifth gear to fourth gear, caution should be taken not to inadvertently press thegear lever sideways in such a man- ner that second gear is engaged. Such a drastic downshift may causethe engine speed to increase to the point that the tachometer will enter the red-zone. Such over-revving ofthe engine may possibly cause en- gine damage.

C090H01L-GAT NOTE:
o For smooth and safe operation,
depress the brake pedal when shifting from "Neutral" positionor "Park" position to a forward or reverse gear.
o The ignition key must be in the "ON" position and the brake pedalfully depressed in order to move the shift lever from the "P" (Park)position to any of the other posi- tions.
o It is always possible to shift from "R", "N", "D" position to "P" po-sition. The vehicle must be fully stopped to avoid transaxle dam-age. C090I01L-GAT
CAUTION:
o Shift into "R" and "P" position only when the vehicle has com- pletely stopped.
o Do not accelerate the engine in
reverse or any of the forwardpositions with the brakes applied.
o Always apply the footbrake when shifting from "P" or "N", to "R" or"D" position.
o Do not use the "P" (Park) posi-
tion in place of the parking brake.Always set the parking brake, shift the transaxle into "P" (Park)position and turn off the ignition when you leave the vehicle, even momentarily. Never leave the ve-hicle unattended while the en- gine is running.
o Check the automatic transaxle
fluid level regularly, and add fluidas necessary.
o See the maintenance schedule
for the proper fluid reco-mendation. C090N02O-AAT Good Driving Practices
o Never move the gear selector lever
from "P" or "N" to any other position with the accelerator pedal de- pressed.
o Never move the gear selector lever
into "P" when the vehicle is in mo-tion.
o Be sure the car is completely stopped before you attempt to shift into "R".
o Never take the car out of gear and
coast down a hill. This may be ex- tremely hazardous. Always leave the car in gear when moving.
o Do not "ride" the brakes. This can
cause them to overheat and mal-function. Instead, when you are driv- ing down a long hill, slow down andshift to a lower gear. When you do this, engine braking will help slow the car.
o Slow down before shifting to a lower gear. Otherwise, the lower gear maynot be engaged.
o Always use the parking brake. Do not depend on placing the transaxlein "P" to keep the car from moving.
o Exercise extreme caution when driv- ing on a slippery surface. Be espe-cially careful when braking, acceler-

C150A01A-AAT SMOOTH CORNERING Avoid braking or gear changing in cor- ners, especially when roads are wet. Ideally, corners should always be takenunder gentle acceleration. If you follow these suggestions, tire wear will be held to a minimum.
o Don't "ride" the brake or clutch pedal.
This can increase fuel consumptionand also increase wear on thesecomponents. In addition, driving with your foot resting on the brake pedal may cause the brakes to overheat,which reduces their effectiveness and may lead to more serious con- sequences.
o Take care of your tires. Keep them inflated to the recommended pres-sure. Incorrect inflation, either toomuch or too little, results in unnec- essary tire wear. Check the tire pres- sures at least once a month.
o Be sure that the wheels are aligned correctly. Improper alignment canresult from hitting curbs or drivingtoo fast over irregular surfaces. Poor alignment causes faster tire wear and may also result in other prob-lems as well as greater fuel con- sumption.
o Keep your car in good condition. For better fuel economy and reducedmaintenance costs, maintain your car in accordance with the mainte-nance schedule in Section 5. If you drive your car in severe conditions, more frequent maintenance is re-quired (see Section 5 for details). o Keep your car clean. For maximum
service, your Hyundai should bekept clean and free of corrosivematerials. It is especially important that mud, dirt, ice, etc. not be al- lowed to accumulate on the under-side of the car. This extra weight can result in increased fuel con- sumption and also contribute to cor-rosion.
o Travel lightly. Don't carry unneces-
sary weight in your car. Weight re-duces fuel economy.
o Don't let the engine idle longer than
necessary. If you are waiting (andnot 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 soonas the engine is running smoothly,you can drive away. In very cold weather, however, give your engine a slightly longer warm-up period. o Don't "lug" or "over-rev" the engine.
Lugging is driving too slowly in toohigh a gear resulting in the enginebucking. 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 oper-ated by engine power so your fuel economy is reduced when you useit.

C190B01S-AAT Trailer Hitches Select the proper hitch and ball combi- nation, making sure that it's location is compatible with that of the trailer or vehicle being towed. Use a quality non-equalizing hitch whichdistributes the tongue load uniformly throughout the chassis. The hitch should be bolted securely to the car and installed by a qualified technician. DO NOT USE A HITCHDESIGNED FOR TEMPORARY IN- STALLATION AND NEVER USE ONE THAT ATTACHES ONLY TO THEBUMPER.
C180A01A-AAT USE OF LIGHTS Check your lights regularly for correct operation and always keep them clean.When driving during the day in condi- tions of poor visibility, it is helpful to drive with headlights on low beam.This enables you to be seen as well as to see. C190A01A-GAT TRAILER OR VEHICLE TOWING If you are considering towing with your car, you should first check with your Province Department of Motor Vehicles to determine their legal requirements.Since laws vary from province to prov- ince the requirements for towing trail- ers, cars, or other types of vehicles orapparatus may differ. Ask your Hyundai dealer for further details before towing.
CAUTION:
Do not do any towing with your carduring its first 2,000 km (1,200 miles) in order to allow the engine to prop-erly break in. Failure to heed this caution may result in serious en- gine or transaxle damage.

C170A01A-AAT HIGH SPEED MOTORING Pre-Trip Inspections 1. Tires: Adjust the tire inflation pressures to specification. Low tire inflation pres-sures will result in overheating and possible failure of the tires. Avoid using worn or damaged tireswhich may result in reduced traction or tire failure. NOTE: Never exceed the maximum tire in- flation pressure shown on the tires. 2. Fuel, engine coolant and engine oil: High speed travel consumes more fuel than urban motoring. Do not forget tocheck both engine coolant and engine oil. 3. Drive belt: A loose or damaged drive belt may result in overheating of the engine.

C190C01Y-GAT Trailer Brakes If your trailer is equipped with a braking system, make sure it conforms to fed-eral and/or local regulations and that it is properly installed and operating cor- rectly. NOTE: If you tow a trailer or vehicle, your
car will require more frequent main- tenance due to the additional load.See "Maintenance Under Severe Usage Conditions" on page 5-6.
CAUTION:
o Never connect a trailer brake sys- tem directly to the vehicle brake system.
o When towing a trailer on steep
grades (in excess of 12%) pay
close attention to the engine cool- ant temperature gauge to ensure the engine does not overheat. Ifthe needle of the coolant tem-
perature gauge moves across the dial towards "H" (HOT), pull overand stop as soon as it is safe to

C190D01A-GAT Safety Chains Should the hitch connection between your car and the trailer or vehicle youare towing fail, the trailer or vehicle could wander dangerously across other lanes of traffic and ultimately collidewith another vehicle. To eliminate this potentially dangerous situation, safety chains, attached between your car and the trailer or towed vehicle, are re- quired in most provinces.
Tongue loads can be increased ordecreased by redistributing the load inthe trailer. This can be verified by checking the total weight of the loaded trailer andthen checking the load on the tongue. NOTE:
1. Never load the trailer with more
weight in the back than in the front. About 60% of the trailer load should be in the front half on the trailer and the remaining40% in the rear.
do so, and allow the engine to idle until it cools down. You may proceed once the engine hascooled sufficiently.

C190F01Y-GAT Trailer or Vehicle Towing Tips
1. Before towing, check hitch and
safety chain connections as well as proper operation of the trailer run- ning lights, brake lights, and turn signals.
2. Always drive your vehicle at a mod- erate speed (Less than 100 km/h)
3. Trailer towing requires more fuel than normal conditions.
4. To maintain engine braking effi-
ciency and electrical charging per-formance, do not use fifth gear (manual transaxle).
5. Always secure items in the trailer to
prevent load shift while driving.
6. Check the condition and air pres-
sure of all tires on the trailer and your car. Low tire pressure can seriously affect the handling. Also check the spare tire. 10.During your trip, check occasion-
ally to be sure that the load issecure, and that the lights and anytrailer brakes are still working.
11.Avoid jerky starts, sudden accel-
eration 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, re- sulting in reduced braking efficien-cy.
14.When going down a hill, shift into a
lower gear and use the engine brak-ing effect. When ascending a long grade, downshift the transaxle to a lowergear 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 inplace by pressing on the accelera-tor. This can cause the automatic transaxle to overheat. Use the park- ing brake or footbrake.
7. The vehicle/trailer combination is
more affected by crosswind andbuffeting.When being passed by a large ve- hicle, keep a constant speed and steer straight ahead. If there is toomuch 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 followall the normal precautions. Turnyour 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 mov-ing, and then apply the trailer brakecontroller by hand to be sure the brakes are working. This lets you check your electrical connection atthe same time.

NOTE: When towing, check transaxle fluid more frequently.
CAUTION:
If overheating should occur whentowing, (temperature gauge reads near red zone), taking the followingaction 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 neu-tral and idle the engine at a higher speed.
