DRIVING YOUR HYUNDAI 2- 21
C190F01Y-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).
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. Also check the spare tire. 10.During your trip, check occasion-
ally to be sure that the load issecure, and that the lights and anytrailer 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 could cause the brakes to overheat, re- sulting in reduced braking efficien-cy.
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.
7. The vehicle/trailer combination is
more affected by crosswind andbuffeting.When being passed by a large ve- hicle, keep a constant speed and steer straight ahead. If there is toomuch 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. Turnyour 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 mov-ing, and then apply the trailer brakecontroller by hand to be sure the brakes are working. This lets you check your electrical connection atthe same time.

2- 22 DRIVING YOUR HYUNDAI
NOTE: When towing, check transaxle fluid more frequently.
CAUTION:
If overheating should occur whentowing, (temperature gauge reads near red zone), taking the followingaction 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 selector in park or neu-tral and idle the engine at a higher speed.

3- 4 WHAT TO DO IN AN EMERGENCY
check for coolant leaking from the radiator, hoses or under the car. (If the air conditioning had been in use,it is normal for cold water to be draining from it when you stop).
WARNING:
While the engine is running, keep hair, hands, and clothing away frommoving parts such as the fan and drive belts to prevent injury.
5. If the water pump drive belt is bro- ken or engine coolant is leaking out, stop the engine immediately and call the nearest Hyundai dealer for assistance.
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.
D030A01A-AAT IF THE ENGINE OVERHEATS If your temperature gauge indicates overheating, you experience a loss ofpower, or hear loud pinging or knock- ing, the engine is probably too hot. 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" (automatic), 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 un-
der the car or steam is coming outfrom the hood, stop the engine. Do not open the hood until the enginecoolant has stopped running or the steaming has stopped. If there is no visible loss of coolant and no steam,leave the engine running and check to 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 the drive belt seems to be satisfactory, 6. If you cannot find the cause of the
overheating, wait until the engine temperature has returned normal.Then, if the engine coolant has been lost, carefully add engine coolant to the reservoir (page 6-9) to bring thefluid level in the reservoir up to the halfway mark.
7. Proceed with caution, keeping alert for further signs of overheating. Ifoverheating happens again, call a Hyundai dealer for assistance.
CAUTION:
Serious loss of engine coolant indi-cates there is a leak in the cooling system and this should be checked as soon as possible by a Hyundaidealer.
