C190F01A-GAT Trailer or Vehicle Towing Tips
1. Before towing, check hitch andsafety 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) or overdrive (au- tomatic 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 se- riously affect the handling. Alsocheck the spare tire.
7. The vehicle/trailer combination is
more affected by crosswind andbuffeting. When being passed by a large vehicle, keep a constant speed and steer straight ahead. If there istoo much 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. Turn your front wheel into the curb, set the parking brake firmly, and put thetransaxle in 1st or Reverse (manual) or Park (automatic). In addition, place wheel chocks at each of thetrailer's tires.
9. If the trailer has electric brakes,
start your vehicle and trailer mov-ing, and then apply the trailer brake controller by hand to be sure the brakes are working. This lets youcheck your electrical connection at the same time.
10.During your trip, check occasion- ally to be sure that the load issecure, and that the lights and any trailer 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 couldcause the brakes to overheat, re- sulting in reduced braking efficiency. 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 lower gear and reduce speed toreduce chances of engine over- loading 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 automatictransaxle to overheat. Use the park- ing brake or foot brake.
NOTE: When towing, check transaxle fluid more frequently.

IF THE ENGINE WILL NOT START
D010A01A-AAT D010B01TG-AAT If Engine Doesn't Turn Over or Turns Over Slowly
1. 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, 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 "JumpStarting" 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 aHyundai dealer or seek other quali-fied assistance.
D010C01Y-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. Re-connect any that may be disconnected or loose.
3. Check the fuel line in the engine room.
4. If engine still refuses to start, call a Hyundai dealer or seek other quali- fied assistance.
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.

IF THE ENGINE OVERHEATS
(If the air conditioning had been in use, it is normal for cold water to bedraining from it when you stop).
D030A01TG-AAT If your temperature gauge indicates overheating, you experience a loss of power, or hear loud pinging or knock- ing, the engine is probably too hot. Ifthis 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"
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 fromthe hood, stop the engine. Do not open the hood until the engine coolant has stopped running or thesteaming has stopped. If there is no visible loss of coolant and no steam, leave the engine running and checkto 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 thedrive belt seems to be satisfactory, check for engine coolant leaking from the radiator, hoses or under the car.
6. Carefully remove the jumper cables
in the reverse order of attachment.
If you do not know why your batterybecame discharged (because the lightswere left on, etc.), have the charging system checked by your Hyundai dealer. WARNING:
While the engine is running, keephands and clothing away from mov-ing parts such as the fan and drive belts to prevent injury.
5. If the water pump drive belt is broken or coolant is leaking out, stop theengine immediately and call the near- est Hyundai dealer for assistance.
WARNING:
Do not remove the radiator cap whenthe engine is hot. This can allow coolant to be blown out of the open- ing and cause serious burns.

You need a helper to check the brake
pedal clearance. With the engine run- ning, have your helper press down on the brake pedal several times and thenhold it down with a force of about 490N (50 kg, 110 lbs). The brake pedal clearance is the distance from the topsurface of the brake pedal to the as- phalt sheeting under the floor mat. If the brake pedal clearance is not withinthe limits specified in the illustration, have it inspected by your Hyundai dealer and adjusted or repaired if nec-essary.
With the engine off, press down on the
brake pedal several times to reduce the vacuum in the brake booster.
Then, using your hand, press down
slowly on the brake pedal until you feel a change in resistance. This isthe brake pedal free-play. The free- play should be within the limits speci- fied in the illustration. If it is not, haveit inspected by your Hyundai dealer and adjusted or repaired if necessary. G160A01TG
3~8 mm (0.12~0.31 in.)To check the steering wheel free-play, stop the car with the wheels pointed straight ahead and gently move the steering wheel back and forth. Usevery light finger pressure and be sen- sitive to changes in resistance that mark the limits of the free-play. If thefreeplay is greater than specified, have it inspected by your Hyundai dealer and adjusted or repaired if necessary. HTG5020

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 "fusepuller" tool is contained in the relay and fuse box of the engine room to simplify this operation).
G200B02NF
3. Be sure to check all other fuses even if you find one that appears tohave burned out.G200B01NF-GAT Replacing Accessory Fuse
G200B01TG
The fuse box for the lights and other electrical accessories will be found in the left side of the crash pad. Insidethe box you will find a list showing the circuits protected by each fuse. If any of your car's lights or other electrical accessories stop working, a blown fuse could be the reason. If the fuse has burned out, you will see thatthe metal strip inside the fuse has burned through. If you suspect a blown fuse, follow this procedure:
CAUTION:
When replacing a fusible link, never
use anything but a new fusible link with the same or lower amper- age rating. Never use a piece ofwire or a higher-rated fusible link. This could result in serious dam- age and create a fire hazard.

G290A01NF
Before performing aiming adjustment, make sure of the following.
1. Keep all tires inflated to the correct pressure.
2. Place the vehicle on level ground and press the front bumper & rear bumper down several times. Place vehicle at a distance of 3m (118 in.) from the test wall.
3. See that the vehicle is unloaded (except for full levels of coolant,engine oil and fuel, and spare tire,jack, and tools). Have the driver or equivalent weight placed in driver's seat.
Vertical aiming
Horizontal aiming 4. Clean the headlight lenses and turn
on the headlights (Low Beam or High Beam).
5. Open the hood.
6. Draw the vertical line (through the center of each headlight beam pat- tern) and the horizontal line (throughthe center of each headlight beam pattern) on the aiming screen. And then, draw the parallel line at 30 mm (1.18 in.) under the hori- zontal line.
7. Adjust each cut-off line of the low beam to the parallel line with a phillips screwdriver - VERTICAL AIMING.
8. Adjust each cut-off line of the low beam to the each vertical line with a phillips screwdriver - HORIZON-TAL AIMING.
NOTE: Grinding noise from the power steering pump may be heard im-mediately after the engine is started in extremely cold conditions (be- low - 20°C). If the noise stops dur-ing warm up, there is no abnormal function in the system. It is due to a power steering fluid characteristicin extremely cold conditions.
Recommended Fluid Use PSF-3 type fluid. NOTE: Do not start the engine when the power steering oil reservoir is empty. G240A01A-AAT POWER STEERING HOSES It is suggested that you check the power steering hose connections forfluid leakage at regular intervals. The power steering hoses should be re- placed if there is severe surface crack-ing, pulling, scuffing or worn spots. Deterioration of the hose could cause premature failure.
