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.!
