DRIVING YOUR HYUNDAI 2- 15
C150A01A-AAT SMOOTH CORNERING Avoid braking or gear changing in cor- ners, especially when roads are wet.Ideally, corners should always be takenunder gentle acceleration. If you followthese suggestions, tire wear will be held to a minimum. C160A01A-AAT WINTER DRIVING The more severe weather conditions of winter result in greater wear andother problems. To minimize the prob-lems of winter driving, you should fol-low these suggestions:
o Keep your car in good condition. For
better fuel economy and reducedmaintenance costs, maintain yourcar in accordance with the mainte-nance schedule in Section 5. If you drive your car in severe conditions, more frequent maintenance is re-quired (see Section 5 for details).
o Keep your car clean. For maximum service, your Hyundai should bekept clean and free of corrosive materials. It is especially important that mud, dirt, ice, etc. not be al-lowed to accumulate on the under-side of the car. This extra weightcan result in increased fuel con-sumption and also contribute to cor- rosion.
o Travel lightly. Don't carry unneces- sary weight in your car. Weight re- duces fuel economy.
o Don't let the engine idle longer than
necessary. If you are waiting (and not in traffic), turn off your engine and restart only when you're readyto go. C160B01A-GAT Snowy or Icy Conditions To drive your vehicle in deep snow, it may be necessary to use snow tires or to install tire chains on your tires. Ifsnow tires are needed, it is necessaryto select tires equivalent in size andtype of the original equipment tires. Failure to do so may adversely affect the safety and handling of your car.Furthermore, speeding, rapid accel-eration, sudden brake applications, andsharp turns are potentially very haz-ardous practices. During deceleration, use engine brak- ing to the fullest extent. Sudden brakeapplications on snowy or icy roadsmay cause skids to occur. You need tokeep sufficient distance between thevehicle in front and your vehicle. Also, apply the brake gently. It should be
o Remember, your Hyundai does not
require extended warm-up. As soon as the engine is running smoothly,you can drive away. In very coldweather, however, give your engine a slightly longer warm-up period.
o Don't "lug" or "over-rev" the engine. Lugging is driving too slowly in too high a gear resulting in the enginebucking. If this happens, shift to alower gear. Over-revving is racing the engine beyond its safe limit. This can be avoided by shifting atthe recommended speeds.
o Use your air conditioning sparingly. The air conditioning system is oper-ated by engine power so your fuel economy is reduced when you use it.

3- 4 WHAT TO DO IN AN EMERGENCY
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 bedraining from it when you stop).
WARNING:
While the engine is running, keephair, hands, and clothing away frommoving parts such as the fan anddrive belts to prevent injury.
5. If the water pump drive belt is bro- ken or engine coolant is leaking out, stop the engine immediately andcall the nearest Hyundai dealer forassistance.
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. 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" (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. Donot open the hood until the engine coolant has stopped running or the steaming has stopped. If there is novisible loss of coolant and no steam,leave the engine running and checkto be sure the engine cooling fan isoperating. 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, 6. If you cannot find the cause of the
overheating, wait until the enginetemperature has returned to nor-mal. Then, if the engine coolant hasbeen lost, carefully remove the ra- diator cap and add engine coolant to bring the fluid level in the reservoirup 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 coolingsystem and this should be checkedas soon as possible by a Hyundai dealer.

AIR CONDITIONING CARE Keeping the Condenser Clean
The air conditioner condenser (and engine radiator) should be checkedperiodically for accumulation of dirt, dead insects, leaves, etc. These can interfere with maximum cooling effi-ciency. When removing such accu- mulations, brush or hose them away carefully to avoid bending the coolingfans. G140B01A-AAT
Checking the Air Conditioning Operation
1. Start the engine and let it run at
fast idle for several minutes with the air conditioning set at the maxi-mum cold setting.
2. If the air coming out of the in-dash vents is not cold, have the air con-ditioning system inspected by your Hyundai dealer. G140C01A-AAT Lubrication To lubricate the compressor and the seals in the system, the air condition-ing should be run for at least 10 minutes each week. This is particu- larly important during cool weatherwhen the air conditioning system is not otherwise in use.CAUTION:
Running the air conditioning sys- tem for extended periods of time with a low refrigerant level may damage the compressor.
G130B02A-AAT To Replace the Fluid Recommended brake fluid conform- ing to DOT 3 or DOT 4 specification should be used. The reservoir cap must be fully tightened to avoid con-tamination from foreign matter or moisture. NOTE: Do not allow any other liquids to contaminate the brake fluid. Sealdamage will result.
WARNING:
Use caution when handling brakefluid. It can damage your vision ifyou get it in your eyes. It will also damage your vehicle's paint if spilled on it and not removed im-mediately.

CHANGING THE AIR FILTER (For Evaporator and Blower Unit)
The air filter is located in front of the
evaporator unit behind the glove box. It helps to decrease pollutants from
entering the car and to filter the air.
B760A01L
Stopper
1. Open the glove box. Remove the stoppers on the both sides of the glove box. 2. Lower the glove box down com-
pletely after taking out the damperstrap from the hole.

3. Remove the glove box mounting bolts (1) and screws (2) from theglove box assembly, and then de-tach the glove box assembly.

G140D01S-GAT Checking the Compressor Drive Belt When the air conditioning is being used regularly, the compressor drive belt tension should be checked at least once a month. To check the drive belt tension, press down on the belt halfway between the engine crankshaft and compressorpulleys. Pressing with your finger, you should not be able to deflect this belt anymore than 8.0 mm. If you have
the instruments to check it with a force of 98N (22 lb.), the deflection should be approx. 8.0 mm (0.315inches). If the belt is too loose, have it adjusted by your Hyundai dealer. G140D01L
