DRIVING YOUR HYUNDAI
2- 12 The hitch should be bolted securely to the car and installed by a qualified technician. DO NOT USE A HITCH DESIGNED FOR TEMPORARY INSTALLATION AND NEVER USE ONE THAT ATTACHES ONLY TO THE BUMPER. C190C03S-GAT Trailer Brakes If your trailer is equipped with a braking system, make sure it conforms to federal and/or local regulations and that it is properly installed and operating correctly. NOTE: If you tow a trailer or vehicle, your car will require more frequent maintenance due to the additional load. See "Maintenance Under Severe Usage Conditions" on page 5-5. CAUTION:
o Never connect a trailer brake system di-
rectly to the vehicle brake system.
o When towing a trailer on steep grades (in excess of 12%) pay close attention to theengine coolant temperature gauge to en- sure the engine does not overheat. If the needle of the coolant temperature gauge moves across the dial towards "H" (HOT), pull over and stop as soon as it is safe to do so, and allow the engine to idle until it cools down. You may proceed once the engine has cooled sufficiently.
C180A01A-AAT USE OF LIGHTS Check your lights regularly for correct operation and always keep them clean. When driving dur- ing the day in conditions of poor visibility, it is helpful to drive with headlights on low beam. This enables you to be seen as well as to see. C190A02A-GAT TRAILER OR VEHICLE TOWINGIf you are considering towing with your car, you should first check with your Province Depart- ment of Motor Vehicles to determine their legal requirements. Since laws vary from province to province, the requirements for towing trailers, cars, other types of vehicles, or apparatus 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 properly break in. Failure to heed this caution may result in serious en- gine or transaxle damage. C190B01S-AAT Trailer Hitches Select the proper hitch and ball combination, making sure that it’s location is compatible with that of the trailer or vehicle being towed. Use a quality non-equalizing hitch which distrib- utes the tongue load uniformly throughout the chassis.
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 you may want to carry include tire chains, tow straps or chains, flashlight, emergency flares, sand, a shovel, jumper cables, a window scraper, gloves, ground cloth, coveralls, a blanket, etc. C170A01A-AAT HIGHER SPEED MOTORING Pre-Trip Inspections 1. Tires: Adjust the tire inflation pressures to specifica- tion. Low tire inflation pressures will result in overheating and possible failure of the tires. Avoid using worn or damaged tires which may result in reduced traction or tire failure. NOTE: Never exceed the maximum tire inflation pres- sure shown on the tires. 2. Fuel, engine coolant and engine oil: High speed travel consumes 1.5 times more fuel than urban motoring. Do not forget to check both engine coolant and engine oil. 3. Drive belt: A loose or damaged drive belt may result in overheating of the engine.

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 tire pressure 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, keep a constant speed and steer straight ahead. If there is too 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 follow all the normal precautions. Turn your 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 moving, and then apply the trailer brake controller by hand to be sure the brakes are working. This lets you check your electrical connection at the same time.
10. During your trip, check occasionally to be
sure that the load is secure, and that the lights 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 the transaxle to a lower gear 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 in place by pressing on the accelerator. This can cause the automatic transaxle to overheat. Use the parking brake 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 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 selection in park or neutral and idle the engineat a higher speed.
C190F02A-GAT Trailer or Vehicle Towing Tips
1. Before towing, check hitch and safety chain
connections as well as proper operation of the trailer running lights, brake lights, and turn signals.
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 use fifth gear (manual transaxle) or overdrive (automatic transaxle).

WHAT TO DO IN AN EMERGENCY 3-3
WARNING: While the engine is running, keep hair, hands, and clothing away from moving 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 the engine im- mediately and call the nearest Hyundai deal- er for assistance.
WARNING: Do not remove the radiator cap when the engine is hot. This can allow coolant to be blown out of the opening and cause serious burns. WARNING (Diesel only): Never work on injection system with engine running or within 30 seconds after shutting off engine. High pressure pump, rail, injec- tors and high pressure pipes are subject to high pressure even after the engine stopped. The fuel jet produced by fuel leaks may cause serious injury, if it touch the body. People using pacemakers should not move than 30cm closer to the ECU or wiring harness within the engine room while engine is running, since the high currents in the Common Rail system produce considerable magnetic fields. 2. The spare tire should only be used temporari-
ly and should be returned to the luggage compartment as soon as the original tire can be repaired or replaced.
3. Continuous use at speeds of over 80 km/h (50 mph) is not recommended.
4. As the temporary spare tire is specifically designed for your car, it should not be used on any other vehicle.
5. The temporary spare tire should not be used
on any other wheels, nor should standard tires, snow tires, wheel covers or trim rings be used with the temporary spare wheel. If such use is attempted, damage to these items or other car components may occur.
6. The temporary spare tire pressure should be
checked once a month while the tire is stored.
CAUTION:
o Do not use snow chains with your tempo- rary spare tire.
o Do not use more than one temporary spare tire at a time.
D040A01FC-GAT TEMPORARY SPARE TIRE The following instructions for the temporary spare tire should be observed:
1. Check inflation pressure as soon as possible
after installing the spare tire, and adjust to the specified pressure. The tire pressure should be periodically checked and maintained at the specified pressure while the tire is stored.
Inflation Pressure
Tire Size
T115/70R(D)15 420 kPa (60 psi)

6. If you cannot find the cause of the overheat-
ing, wait until the engine temperature has returned to normal. Then, if the engine cool- ant has been lost, carefully remove the radia- tor cap and add engine coolant to bring the fluid level in the reservoir up to the halfway mark.
7. Proceed with caution, keeping alert for fur- ther signs of overheating. If overheating hap- pens again, call a Hyundai dealer for assis- tance.
CAUTION: Serious loss of engine coolant indicates there is a leak in the cooling system and this should be checked as soon as possible by a Hyundai dealer.

WHAT TO DO IN AN EMERGENCY
3-8 D080A02A-GAT IF YOUR CAR MUST BE TOWED CAUTION: Your car can be damaged if towed incorrect- ly! If your car has to be towed, it should be done by your Hyundai dealer or a commercial tow truck service. This will help assure that your car is not damaged in towing. Also, professionals are gen- erally aware of local laws governing towing. In any case, rather than risk damage to your car, it is suggested that you show this information to the tow truck operator. Be sure that a safety chain system is used and that all local laws are ob- served.
D080B01A-AAT Towing a Car with a Manual Transaxle
o If the car is being towed with the rear wheels
on the ground, be sure the parking brake is released.
o If the car is being towed with the front wheels on the ground, be sure that the transaxle is in neutral. Also, be sure that the ignition key is in the "ACC" position. This is necessary to prevent damage to the steering lock mecha- nism, which is not designed to hold the front wheels straight while the car is being towed.
o If any of the loaded wheels or suspension
components are damaged, a towing dolly must be used.

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 recommended, drive slowly to the nearest service station and inflate to the correct pressure. If it is too high, adjust it until it is correct. Always reinstall the valve cap after checking or adjusting tire pressure. If the cap is not replaced, air may leak from the tire. If you lose a valve cap, buy another and install it as soon as possible. After you have changed wheels, always secure the flat tire in its place in the luggage room and return the jack and tools to their proper storage locations.

F060A01A-AAT EXPLANATION OF SCHEDULED MAINTENANCE ITEMS F060M01A-AAT o Engine Oil and FilterThe engine oil and filter should be changed at
the intervals specified in the maintenance sched- ule. If the car is being driven in severe condi- tions, more frequent oil and filter changes are required. F060B01A-AAT
o Drive BeltsInspect all drive belts for evidence of cuts, cracks, excessive wear or oil saturation and replace if necessary. Drive belts should be checked periodically for proper tension andadjusted as necessary. F060C01A-AAT
o Fuel FilterA clogged filter can limit the speed at which the vehicle may be driven, damage the emission system and cause hard starting. If an exces- sive amount of foreign matter accumulates in the fuel tank, the filter may require replacement more frequently. After installing a new filter, run the engine for several minutes, and check for leaks at the connections. Fuel filters should be installed by trained technicians.
F060D02A-AAT
o Fuel Lines, Fuel Hoses and
Connections
Check the fuel lines, fuel hoses and connec- tions for leakage and damage. Have a trained technician replace any damaged or leaking parts immediately. WARNING (Diesel only): Never work on injection system with engine running or within 30 seconds after shutting off engine. High pressure pump, rail, injec- tors and high pressure pipes are subject to high pressure even after the engine stopped. The fuel jet produced by fuel leaks may cause serious injury, if it touch the body. People using pacemakers should not move than 30cm closer to the ECU or wiring har- ness within the engine room while engine is running, since the high currents in the Com- mon Rail system produce considerable mag- netic fields.
