C190F01A-GAT Trailer or Vehicle Towing Tips
1. Before towing, check hitch and safety chainconnections as well as proper operation of the trailer running lights, brake lights, and turnsignals.
2. Always drive your vehicle at a moderate speed (Less than 100 km/H).
3. Trailer towing requires more fuel than normal conditions.
4. To maintain engine braking efficiency and electrical charging performance, do not usefifth gear (manual transaxle) or overdrive(automatic transaxle).
5. Always secure items in the trailer to prevent load shift while driving.
6. Check the condition and air pressure of all tires on the trailer and your car. Low tirepressure can seriously affect the handling.Also check the spare tire.
7. The vehicle/trailer combination is more af- fected by crosswind and buffeting.When being passed by a large vehicle, keepa constant speed and steer straight ahead. Ifthere is too much wind buffeting, slow down toget out of the other vehicle's air turbulence.
8. When parking your car and trailer, especially on a hill, be sure to follow all the normalprecautions. Turn your front wheel into thecurb, set the parking brake firmly, and put thetransmission in 1st or Reverse (manual) orPark (automatic). In addition, place wheelchocks at each of the trailer's tires.

9. If the trailer has electric brakes, start your
vehicle and trailer moving, and then apply the trailer brake controller by hand to be sure thebrakes are working. This lets you check yourelectrical connection at the same time.
10. During your trip, check occasionally to be sure that the load is secure, and that thelights and any trailer brakes are still working.
11. Avoid jerky starts, sudden acceleration 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 brakesto overheat, resulting in reduced braking effi-ciency.
14. When going down a hill, shift into a lower gear and use the engine braking effect.When ascending a long grade, downshift thetransmission to a lower gear and reducespeed to reduce chances of engine overload-ing and/or overheating.
15. If you have to stop while going uphill, do not hold the vehicle in place by pressing on theaccelerator. This can cause the automatictransmission to overheat. Use the parkingbrake or footbrake. NOTE:When towing check transaxle fluid more fre-quently. CAUTION: If overheating should occur when towing,(temperature gauge reads near red zone),taking the following action may reduce oreliminate 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 neutral and idle theengine at a higher speed.

tance. Automobile batteries contain sulfuric acid. This is poisonous and highly corrosive.When jump starting, wear protective glassesand 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, immediately remove any contaminated clothing and flush the area withclear water for at least 15 minutes. Thenpromptly obtain medical attention. If you mustbe transported to an emergency facility, con-tinue to apply water to the affected area witha sponge or cloth.
o The gas produced by the battery during the jump-start operation is highly explosive. Donot smoke or allow a spark or open flame inthe vicinity.
o The battery being used to provide the jump start must be 12-volt. If you cannot determinethat it is a 12-volt battery, do not attempt touse it for the jump start.
o To jump start a car with a discharged battery, follow this procedure exactly:
1. If the booster battery is installed in another vehicle, be sure the two vehicles are nottouching.
2. Turn off all unnecessary lights and acces- sories in both vehicles. 3. Attach the clamps of the jumper cable in the
exact location shown on the previous page.First, attach one clamp of the jumper cable tothe positive (+) post or cable of the dis-charged battery. Then attach the other end ofthe same cable to the positive (+) post orcable of the booster battery. Next, using theother cable, attach one clamp to the negative(-) post or cable of the booster battery. Thenattach the other end of that cable to a solidmetal part of the engine away from thebattery. Do not connect the cable to anymoving part.
4. Start the engine in the car with the booster battery and let it run for a few minutes. Thiswill help to assure that the booster battery isfully charged. During the jumping operation,run the engine in this vehicle at about 2000rpm.
5. Start the engine in the car with the discharged battery using the normal starting procedure.After the engine starts, leave the jumpercables connected and let the engine run atfast idle or about 2000 rpm for several min-utes.
6. Carefully remove the jumper cables in the reverse order of attachment.
If you do not know why your battery becamedischarged (because the lights were left on,etc.), have the charging system checked by yourHyundai dealer. D030A02A-AAT IF THE ENGINE OVERHEATSIf your temperature gauge indicates overheating, you experience a loss of power, or hear loudpinging or knocking, the engine is probably toohot. 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" (auto- matic), 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 under the car or steam is coming out from the hood, stopthe engine. Do not open the hood until theengine coolant has stopped running or thesteaming has stopped. If there is no visibleloss of engine coolant and no steam, leavethe engine running and check to be sure theengine cooling fan is operating. If the fan isnot 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 thatit is tight. If the drive belt seems to be satis-factory, check for engine coolant leaking fromthe radiator, hoses or under the car. (If the airconditioning had been in use, it is normal forcold water to be draining from it when youstop).
WARNING:While the engine is running, keep hair, hands,and clothing away from moving parts such asthe fan and drive belts to prevent injury.

Replacing Accessory Fuse The fuse box for the lights and other electrical accessories will be found low on the dashboardon the driver's side. Inside the box you will find alist showing the circuits protected by each fuse. If any of your car's lights or other electrical
accessories stop working, a blown fuse couldbe the reason. If the fuse has burned out, youwill see that the metal strip inside the fuse hasburned through. If you suspect a blown fuse,follow this procedure:
1. Turn off the ignition and all other switches.
2. Open the fuse box and examine each fuse. Remove each fuse by pulling it toward you (a small "fuse puller" tool is contained in thefuse box to simplify this operation).
3. Be sure to check all other fuses even if you find one that appears to have burned out.

CHECKING AND REPLACING FUSES Replacing a Fusible Link
A fusible link will melt if the electrical circuits
from the battery are ever overloaded, thus pre- venting damage to the entire wiring harness.(This could be caused by a short in the systemdrawing too much current.) If this ever happens,have a Hyundai dealer determine the cause,repair the system and replace the fusible link.The fusible links are located in a relay box foreasy inspection.
CAUTION: When replacing a fusible link, never use
anything but a new fusible link with the same or lower amperage rating. Never use apiece of wire or a higher-rated fusible link.This could result in serious damage andcreate a fire hazard.
