DRIVING YOUR HYUNDAI 2- 15
o Don't "ride" the brake or clutch pedal.
This can increase fuel consumption and 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.
C140A01A-AAT DRIVING FOR ECONOMY You can save fuel and get more miles from your car if you follow these sug-gestions:
o Drive smoothly. Accelerate at a
moderate rate. Don't make "jack- rabbit" starts or full-throttle shifts and maintain a steady cruisingspeed. Don't race between stop- lights. Try to adjust your speed to that of the other traffic so you don'thave to change speeds unneces- sarily. Avoid heavy traffic whenever possible. Always maintain a safedistance from other vehicles so you can avoid unnecessary braking. This also reduces brake wear.
o Drive at a moderate speed. The faster you drive, the more fuel yourcar uses. Driving at a moderatespeed, especially on the highway, is one of the most effective ways to reduce fuel consumption.

2- 16 DRIVING YOUR HYUNDAI
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.
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.
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 "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.

DRIVING YOUR HYUNDAI 2- 17
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. 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.
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.
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.

2- 18 DRIVING YOUR HYUNDAI
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.
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.
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.

WARNING:
Improperly loading your car and trailer can seriously affect its steer- ing and braking performance caus- ing a crash which could cause seri-ous injury or death. 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.
CAUTION:
The following specifications are rec- ommended when towing a trailer. The loaded trailer weight cannotsafely exceed the values in the chart below.
!
!
7. The vehicle/trailer combination is more affected by crosswind and buffeting.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.
!
10.During your trip, check occasion-
ally to be sure that the load is secure, 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.

3- 2 WHAT TO DO IN AN EMERGENCY
D010A01A-AAT IF THE ENGINE WILL NOT START
WARNING:
If the engine will not start, do not push or pull the car to start it. Thiscould result in a collision or cause other damage. In addition, push or pull starting may cause the cata-lytic converter to be overloaded and create a fire hazard. D010B01A-AAT If Engine Doesn't Turn Over or Turns Over Slowly 1. If your car has an automatic
transaxle, be sure the gear selector lever is in "N" or "P" and the emer-gency brake is set.
2. Check the battery connections to be
sure they are clean and tight.
3. Turn on the interior light. If the light dims or goes out when you operatethe starter, the battery is discharged.
4. Check the starter connections to be sure they are securely tightened.
5. Do not push or pull the vehicle to start it. See instructions for "Jump Starting" on the following pages. D010D01A-AAT If Engine Stalls While Driving
1. Reduce your speed gradually, keep-
ing a straight line. Move cautiously off the road to a safe place.
2. Turn on your emergency flashers.
3. Try to start the engine again. If your
vehicle will not start, contact a Hyundai dealer or seek other quali- fied assistance.

WHAT TO DO IN AN EMERGENCY 3- 3
WARNING:
The gas produced by the battery during the jump-start operation is highly explosive. If these instruc- tions are not followed exactly, seri-ous personal injury and damage to the vehicle may occur! If you are not sure how to follow this proce-dure, seek qualified assistance. Automobile batteries contain sul- furic acid. This is poisonous andhighly corrosive. When jump start- ing, wear protective glasses and be careful not to get acid on yourself,your clothing or on the car.
o If you should accidentally get acid on your skin or in your eyes, imme- diately remove any contaminatedclothing and flush the area with clear water for at least 15 minutes. Then promptly obtain medical attention. Ifyou must be transported to an emer- gency facility, continue to apply water to the affected area with a spongeor cloth. o The gas produced by the battery
during the jump-start operation ishighly explosive. Do not smoke orallow a spark or open flame in the vicinity.
o The battery being used to provide the jump start must be 12-volt. If youcannot determine that it is a 12-volt battery, do not attempt to use it forthe jump start.
o To jump start a car with a discharged
battery, follow this procedure ex-actly:
1. If the booster battery is installed in another vehicle, be sure the two vehicles are not touching.
2. Turn off all unnecessary lights and
accessories in both vehicles.
3. Attach the clamps of the jumper
cable in the exact order shown in the illustration. That is, first, attach one clamp of the jumper cable to the positive (+) post or cable of thedischarged battery. Then attach the other end of the same cable to the positive (+) post or cable of thebooster battery. Next, using the other cable, attach one clamp to the negative (-) post or cable of the booster battery. Then attach the other end of that cable to a solid metal part of the engine of the ve-hicle with the discharged battery away from the battery. Do not con- nect the cable to any moving part.
4. Start the engine in the car with the booster battery and let it run for afew minutes. This will help to as-sure that the booster battery is fully charged. During the jumping opera- tion, run the engine in this vehicle atabout 2,000 rpm.
5. Start the engine in the car with the
discharged battery using the nor-mal starting procedure. After the engine starts, leave the jumper cables connected and let the enginerun at fast idle or about 2,000 rpm for several minutes.
6. Carefully remove the jumper cables
in the reverse order of attachment.
If you do not know why your battery became discharged (because the lights were left on, etc.), have the charging system checked by your Hyundaidealer.!

3- 4 WHAT TO DO IN AN EMERGENCY
check for coolant leaking from the radiator, hoses or under the car. (If the air conditioning had been in use,it is normal for cold water to be draining from it when you stop).
WARNING:
While the engine is running, keep hair, hands, and clothing away frommoving parts such as the fan and drive belts to prevent injury.
5. If the water pump drive belt is bro- ken or engine coolant is leaking out, stop the engine immediately and call the nearest Hyundai dealer for assistance.
WARNING:
Do not remove the radiator cap whenthe engine is hot. This can allowcoolant to be blown out of the open- ing and cause serious burns.
D030A01A-AAT IF THE ENGINE OVERHEATS If your temperature gauge indicates overheating, you experience a loss ofpower, or hear loud pinging or knock- ing, the engine is probably too hot. If this happens to you, you should:
1. Pull off the road and stop as soon as
it is safe to do so.
2. Place the gear selector lever in "P" (automatic), or neutral (manual transaxle) and set the parking brake.If the air conditioning is on, turn it off.
3. If engine coolant is running out un- der the car or steam is coming outfrom the hood, stop the engine. Do not open the hood until the enginecoolant has stopped running or the steaming has stopped. If there is no visible loss of coolant and no steam,leave the engine running and check to be sure the engine cooling fan is operating. If the fan is not running,turn the engine off.
4. Check to see if the water pump drive
belt is missing. If it is not missing,check to see that it is tight. If the drive belt seems to be satisfactory, 6. If you cannot find the cause of the
overheating, wait until the engine temperature has returned normal.Then, if the engine coolant has been lost, carefully add engine coolant to the reservoir (page 6-9) to bring thefluid level in the reservoir up to the halfway mark.
7. Proceed with caution, keeping alert for further signs of overheating. Ifoverheating happens again, call a Hyundai dealer for assistance.
CAUTION:
Serious loss of engine coolant indi-cates there is a leak in the cooling system and this should be checked as soon as possible by a Hyundaidealer.

3- 12 WHAT TO DO IN AN EMERGENCY
If the car is being towed with the rear wheels on the ground, be sure the parking brake is released.
o OK FOR AUTOMATIC OR MANUAL TRANSAXLE EQUIPPED VEHICLE D080C01LD080D02A-GAT EMERGENCY TOWING For emergency towing when no com- mercial tow vehicle is available, attach a tow cable, chain or strap to one of the towing hooks under the front/rear ofyour car. Do not attempt to tow your vehicle in this manner on any unpaved surface. This could result in seriousdamage to your car. Nor should towing be attempted if the wheels, drive train, axles, steering orbrakes are damaged. Before towing, be sure the transaxle is in neutral and the key is in "ACC" (with the engine off)or in the "ON" position (with the engine running). A driver must be in the towed car to steer it and operate the brakes. HXGS403J
CAUTION:
If the car is being towed with all fourwheels on the ground, it can betowed only from the front. Be sure that the transaxle is in neutral. Do not tow at speeds greater than 50km/h (30 mph) and for more than 25 km (15 miles). Be sure the steering is unlocked byplacing the key in the "ACC" posi- tion. A driver must be in the towed vehicle to operate the steering andbrakes. D120A01A-GAT IF YOU LOSE YOUR KEYS If you lose your keys, many Hyundai dealers can make you a new key if you have your key number.If you lock the keys inside your car and you cannot obtain a new key, many Hyundai dealers can use special toolsto open the door for you. Information about the key of immobi- lizer system (if installed) will be found on page 1-4.
!
NOTE: Before towing, check the level of the transaxle fluid. If it is below the"HOT" range on the dipstick, add fluid. If you cannot add fluid, a towing dolly must be used.
