DRIVING YOUR HYUNDAI 2- 15
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.

2- 16 DRIVING YOUR HYUNDAI
C160F01A-AAT Check Spark Plugs and Ignition System Inspect your spark plugs as described in Section 6 and replace them if neces-sary. Also check all ignition wiring and components to be sure they are not cracked, worn or damaged in any way.
C160C01A-AAT Use 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 ithelps prevent corrosion in the cooling system, lubricates the water pump and prevents freezing. Be sure to replaceor replenish your coolant in accor- dance with the maintenance schedule in Section 5. Before winter, have yourcoolant tested to assure that its freez- ing point is sufficient for the tempera- tures anticipated during the winter. C160D01A-AAT Check Battery and Cables Winter puts additional burdens on the battery system. Visually inspect thebattery and cables as described in Section 6. The level of charge in your battery can be checked by your Hyun-dai dealer or a service station. C160E01A-AAT Change to "Winter Weight" Oil if Necessary In some climates it is recommended that a lower viscosity "winter weight" oil be used during cold weather. SeeSection 9 for recommendations. If you aren't sure what weight oil you should use, consult your Hyundai dealer.
C160A01A-AAT WINTER DRIVING The more severe weather conditions of winter result in greater wear andother problems. To minimize the prob- lems of winter driving, you should fol- low these suggestions: C160B01A-GAT Snowy 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 necessaryto select tires equivalent in size and type of the original equipment tires. Failure to do so may adversely affectthe safety and handling of your car. Furthermore, speeding, rapid accel- eration, sudden brake applications, andsharp turns are potentially very haz- ardous practices. During deceleration, use engine brak-ing to the fullest extent. Sudden brake applications on snowy or icy roads may cause skids to occur. You need tokeep sufficient distance between the vehicle in front and your vehicle. Also, apply the brake gently. It should be noted that installing 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 prov- inces. Check province laws beforefitting tire chains.

C160G01A-GAT To Keep Locks from Freezing To keep the locks from freezing, squirt an approved de-icer fluid or glycerineinto the key opening. If a lock is cov- ered with ice, squirt it with an approved de-icing fluid to remove the ice. If thelock is frozen internally, you may be able to thaw it out by using a heated key. Handle the heated key with careto avoid injury. NOTE: The proper temperature for using the immobilizer key is from -40°C to80°C. If you heat the immobilizer key over 80°C to open the frozen lock, it may cause damage to thetransponder in its head. C160I01A-AAT Don't Let Your Parking Brake Freeze Under some conditions your parking brake can freeze in the engaged posi- tion. This is most likely to happenwhen there is an accumulation of snow or ice around or near the rear brakes or if the brakes are wet. If there is a riskthe parking brake may freeze, apply it only temporarily while you put the gear selector lever in "P" (automatic) or infirst or reverse gear (manual transaxle) and block the rear wheels so the car cannot roll. Then release the parkingbrake.
C160H01A-AAT Use Approved Anti-Freeze in WindowWasher System To keep the water in the window washer system from freezing, add an approved anti-freeze solution in accordance withinstructions on the container. Window washer anti-freeze is available from Hyundai dealers and most auto partsoutlets. Do not use engine coolant or other types of anti-freeze as these may damage the finish.
C160K01A-AAT Carry Emergency Equipment Depending on the severity of the weather where you drive your car, you should carry appropriate emergency equipment. Some of the items youmay want to carry include tire chains, tow straps or chains, flashlight, emer- gency flares, sand, a shovel, jumpercables, a window scraper, gloves, ground cloth, coveralls, a blanket, etc.
C160J01A-AAT Don't Let Ice and Snow Accumu- late Underneath Under some conditions, snow and ice can build up under the fenders and interfere with the steering. When driv-ing in severe winter conditions where this may happen, you should periodi- cally check underneath the car to besure the movement of the front wheels and the steering components is not obstructed.

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

Tongue load Total trailer weight C190E01L
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.

2- 22 DRIVING YOUR HYUNDAI
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.
