21TRAILER OR VEHICLE TOWING
C190A02A-GAT 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, other types of vehicles, orapparatus may differ. Ask your Hyundai dealer for further details before towing.
CAUTION:
Do not do any towing with your car during its first 2,000 km (1,200 miles) in order to allow the engine to prop- erly break in. Failure to heed thiscaution may result in serious en- gine or transaxle damage.
! C190B01S-AAT Trailer Hitches Select the proper hitch and ball combi- nation, making sure that it's location iscompatible with that of the trailer or vehicle being towed. Use a quality non-equalizing hitch whichdistributes the tongue load uniformly throughout the chassis. The hitch should be bolted securely to the car and installed by a qualified technician. DO NOT USE A HITCHDESIGNED FOR TEMPORARY IN- STALLATION AND NEVER USE ONE THAT ATTACHES ONLY TO THEBUMPER. C190C03S-GAT Trailer Brakes If your trailer is equipped with a braking system, make sure it conforms to fed-eral and/or local regulations and that it is properly installed and operating cor- rectly. NOTE: If you tow a trailer or vehicle, your car will require more frequent main- tenance due to the additional load.See "Maintenance Under Severe Usage Conditions" on page 5-7.
CAUTION:
o Never connect a trailer brake sys- tem directly to the vehicle brakesystem.
o When towing a trailer on steep grades (in excess of 12%) pay close attention to the engine cool-ant temperature gauge to ensure the engine does not overheat. If the needle of the coolant tem-perature gauge moves across the dial towards "H" (HOT), pull over and stop as soon as it is safe todo so, and allow the engine to idle until it cools down. You may proceed once the engine hascooled sufficiently.

WARNING:
Improperly loading your car andtrailer can serious affect its steer-ing and braking performance caus- ing a crash in which could cause serious injury or death. C190F02A-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) 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 seriously 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.

CAUTION:
If overheating should occur when towing, (temperature gauge reads near red zone), taking the following action may reduce or eliminate theproblem.
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 selection in park or neu- tral and idle the engine at a higherspeed.
!
8. When parking your car and trailer,
especially on a hill, be sure to follow all the normal precautions. Turn your front wheel into the curb, set the parking brake firmly, and putthe transaxle in 1st or Reverse (manual) or Park (automatic). In addition, place wheel chocks ateach of the trailer'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 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.
NOTE: When towing check transaxle fluid more frequently.

check for coolant leaking from the radiator, hoses or under the car. (Ifthe air conditioning had been in use, it is normal for cold water to be draining from it when you stop).
WARNING (Diesel only):
Never work on injection system with engine running or within 30 sec- onds after shutting off engine. Highpressure pump, rail, injectors and high pressure pipes are subject to high pressure even after the enginestopped. The fuel jet produced by fuel leaks may cause serious in- jury, if it touch the body. Peopleusing pacemakers should not move than 30cm closer to the ECU or wiring harness within the engine 5. If the water pump drive belt is bro-
ken or coolant is leaking out, stopthe engine immediately and call the nearest Hyundai dealer for assis- tance. CAUTION:
Serious loss of engine coolant indi- cates there is a leak in the cooling system and this should be checkedas soon as possible by a Hyundai dealer.
room while engine is running, since the high currents in the CommonRail system produce considerable magnetic fields.
6. If you cannot find the cause of the
overheating, wait until the engine temperature has returned to nor- mal. Then, if the engine coolant hasbeen lost, carefully add coolant to the reservoir (page 6-14) to bring the fluid level in the reservoir up tothe halfway mark.
WARNING:
While the engine is running, keephair, hands, and clothing away from moving parts such as the fan and drive belts to prevent injury.
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. 7. Proceed with caution, keeping alert
for further signs of overheating. If overheating happens again, call a Hyundai dealer for assistance.

D060J01FC-GAT After Changing Wheels If you have a tire gauge, remove the valve cap and check the air pressure. If the pressure is lower than recom-mended, drive slowly to the nearest service station and inflate to the cor- rect pressure. If it is too high, adjust ituntil it is correct. Always reinstall the valve cap after checking or adjusting tire pressure. If the cap is not replaced, D060B01FC
IF YOUR VEHICLE MUST BE TOWED
D080A01O-GAT If your vehicle has to be towed, it should be done by your Hyundai dealeror a commercial tow truck service. This will help assure that your vehicle is not damaged in towing. Also, profes-sionals are generally aware of local laws governing towing. In any case, rather than risk damage to your car, itis suggested that you show this infor- mation to the tow truck operator. Be sure that a safety chain system is usedand that all local laws are observed. It is recommended that your vehicle be towed with a wheel lift and dollies orflatbed equipment with all the wheels off the ground.
! CAUTION:
o Your vehicle can be damaged if towed incorrectly!
o Be sure the transaxle is in neu-
tral.
o When the engine will not start, be
sure the steering is unlocked by placing the key in the "ACC" po- sition.

8EXPLANATION OF SCHEDULED MAINTENANCE ITEMS
!
F060M01A-AAT o Engine Oil and Filter The engine oil and filter should be changed at the intervals specified in the maintenance schedule. If the car is being driven in severe conditions,more frequent oil and filter changes are required. F060B01A-AAT
o Drive Belts Inspect all drive belts for evidence of cuts, cracks, excessive wear or oil saturation and replace if necessary. Drive belts should be checked periodi-cally for proper tension and adjusted as necessary. F060C01A-AAT
o Fuel Filter
A clogged filter can limit the speed at
which the vehicle may be driven, dam-age the emission system and cause hard starting. If an excessive amountof foreign matter accumulates in the fuel tank, the filter may require re- placement more frequently. After installing a new filter, run the
engine for several minutes, and checkfor leaks at the connections. Fuel fil- ters should be installed by trained technicians. WARNING (Diesel only):
Never work on injection system with engine running or within 30 sec- onds after shutting off engine. Highpressure pump, rail, injectors and high pressure pipes are subject to high pressure even after the enginestopped. The fuel jet produced by fuel leaks may cause serious injury, if it touch the body. People usingpacemakers should not move than 30cm closer to the ECU or wiring harness within the engine roomwhile engine is running, since the high currents in the Common Rail system produce considerable mag-netic fields.
