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.

1. If your car has an automatic transaxle, be sure the gear selector lever is in "N" or "P" and the emergency 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 operate the starter, thebattery 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 follow-ing pages.
D010C01A-AAT If Engine Turns Over Normally but Does Not Start
1 Check fuel level.
2 With the key in the off position, Check all connectors at ignition coils and spark plugs.Reconnect any that may be disconnected orloose.
3 Check the fuel line in the engine room.
4 If engine still refuses to start, call a Hyundai dealer or seek other qualified assistance.
D010D01A-AAT If Engine Stalls While Driving
1. Reduce your speed gradually, keeping 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 seekother qualified assistance. D020A02A-AAT JUMP STARTING

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.

CHECKING THE BATTERY
WARNING: Batteries can be dangerous! When working
with batteries, carefully observe the follow- ing precautions to avoid serious injuries.
The fluid in the battery contains a strong solu-
tion of sulfuric acid, which is poisonous andhighly corrosive. Be careful not to spill it onyourself or the car. If you do spill battery fluid onyourself, immediately do the following:
o If battery fluid is on your skin, flush the affected areas with water for at least 15 minutes and then seek medical assistance.
o If battery fluid is in your eyes, rinse out your eyes with water and get medical assistanceas soon as possible. While you are beingdriven to get medical assistance, continueto rinse your eyes by using a sponge or softcloth saturated with water.
o If you swallow battery fluid, drink a large quantity of water or milk followed by milk ofmagnesia, eat a raw egg or drink vegetableoil. Get medical assistance as soon aspossible.
While batteries are being charged (either by a
battery charger or by the vehicle's alternator),they produce explosive gases. Always observethese warnings to prevent injuries from occur-ring: G210B01A-AAT
Checking the Battery Keep the battery clean. Any evidence of corro-
sion around the battery posts or terminals shouldbe removed using a solution of household bak-ing soda and warm water. After the batteryterminals are dry, cover them with a light coat-ing of grease.
G220A01A-AAT
CHECKING ELECTRIC COOLING FANS WARNING: The cooling fan is controlled by engine cool-
ant temperature and may sometimes oper- ate even when the engine is not running.Use extreme caution when working near theblades of the coolant fan, so that you are notinjured by a rotating fan blade. As the cool-ant temperature decreases the fan will auto-matically shut off. This is a normal condi-tion.
G220B01A-AAT
Checking Engine Cooling Fan The engine coolant fan should come on auto-
matically if the engine coolant temperature ishigh.
o Charge batteries only in a well ventilated
area.

WARNING AND INDICATOR LIGHTS
SB210K1-ELOW OIL PRESSURE WARN ING LAMP
SB210G1-ETURN SIGNAL INDICA- TOR LAMPS
Operation of a turn signal is indicated by the warning lamp located in theinstrument cluster. If the lamp fails to illuminate or does not flash, a malfunc- tion within the turn signal system isindicated. 260P02Y-EAT ABS Service Reminder Indicator (Not all models)
When the key is turned to the "ON" position, the Anti-Lock Brake System SRI will come on and then go off in afew seconds. If the ABS SRI remains on, comes on while driving, or does not come on when the key is turned to the"ON" position, this indicates that there may be a problem with the ABS. If this occurs, have your vehiclechecked by your Hyundai dealer as soon as possible. The normal braking system will still be operational, butwithout the assistance of the anti-lock brake system. WARNING:
If the both ABS SRI and ParkingBrake/Brake fluid level warning lights remain "ON" or come on whiledriving, there may be a problem with E.B.D (Electronic brake force distribution).If this occurs, avoid sudden stops and have your vehicle checked by your Hyundai dealer as soon aspossible.SB210J1-E HIGH BEAM INDICATOR LAMP
The high beam indicator lamp will illu- minate whenever the headlamps areswitched to high beam of flash posi- tion.
CAUTION:
If the oil pressure warning light illuminates when the engine is run- ning, an insufficient oil pressure level for continued safe operationof the engine exists. Continued operation of the engine in this con- dition may result in serious enginedamage. Under normal circumstances, the light will illuminate when the igni- tion is turned "on" and will be extin- guished when the engine is started.
