CHECKING THE BRAKES
CAUTION:
Because brakes are essential to
the safe operation of the car, it is suggested that they be checked and inspected by your Hyundaidealer. The brakes should be checked and inspected for wear at those intervals specified in thevehicle maintenance schedule in Section 5.
G120B01A-A AT
Checking the Brake Fluid Level
WARNING:
Use caution when handling brakefluid. It can damage your vision if it gets into your eyes. It will alsodamage your vehicle's paint if spilled on it and not removed im- mediately.
3. If the transaxle fluid level is low,
use a funnel to add transaxle fluidthrough the dipstick tube until the level reaches the "HOT" range. Do not overfill.
WARNING:
The cooling fan is controlled by
engine coolant temperature andmay sometimes operate even whenthe engine is not running. Use extreme caution when working near the blades of the cooling fan,so that you are not injured by a rotating fan blade. As the engine coolant temperature decreases, thefan will automatically shut off. This is a normal condition.
While the engine is idling, apply the
brakes and move the gear selector lever from "P" to each of its otherpositions -- "R", "N", "D" -- and then return to "N" or "P" with the engine still idling:
1. Open the hood, being careful to
keep hands, long hair and clothing clear of any moving parts.
2. Remove the transaxle dipstick, wipe it clean, reinsert the dipstick as far as it will go, then remove it again.Now check the fluid level on the dipstick. It should be in the "HOT" range on the dipstick. HXG556J

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 CONDI- TIONER FILTER (For Evapora- tor and Blower Unit)
The air conditioner 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.
G145A01L
1. Open the glove box and take out the damper strap from the hole.
G145A02L
2. Lower the glove box completely by
pushing the both sides of the glovebox inward.
B760A08LG140D01S-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

G150A01A-GAT CHECKING STEERING WHEEL FREEPLAY
G150A01L
To check the steering wheel freeplay, stop the car with the wheels pointed straight ahead and gently move thesteering wheel back and forth. Use very light finger pressure and be sen- sitive to changes in resistance thatmark the limits of the freeplay. If the freeplay is greater than specified, have it inspected by your Hyundai dealerand adjusted or repaired if neces- sary. 30 mm(1.18 in.)
4. Turn the knob of the air conditioner filter cover counterclockwise and remove the air conditioner filtercover. 5. Remove the two air conditioner fil-
ters by pulling the knob of the airconditioner filter outward.
6. Replace the two filters.
7. Installation is the reverse order of disassembly.
CAUTION:
Be sure to install it with the direc-
tion of the air conditioner filter checked.

CHECKING THE BATTERY
WARNING:
Batteries can be dangerous! When working with batteries, care-
fully observe the following pre- cautions to avoid serious injuries.
The fluid in the battery contains a
strong solution of sulfuric acid, whichis poisonous and highly corrosive. Be careful not to spill it on yourself or thecar. If you do spill battery fluid on yourself, immediately do the follow- ing:
o If battery fluid is on your skin, flush the affected areas with water for at least 15 minutes and then seek medical assistance.
o If battery fluid is in your eyes, rinse
out your eyes with water and getmedical assistance as soon as possible. While you are being driven to get medical assistance, continueto rinse your eyes by using a sponge or soft cloth saturated with water. o If you swallow battery fluid, drink a
large quantity of water or milk fol-lowed by milk of magnesia, eat araw egg or drink vegetable oil. Get medical assistance as soon as pos- sible.
While batteries are being charged(either by a battery charger or by the vehicle's generator), they produce explosive gases. Always observethese warnings to prevent injuries from occurring:
o Charge batteries only in a well ven- tilated area.
o Do not permit flames, sparks or
smoking in the area.
o Keep children away from the area. G210B01A-AAT Checking the Battery Keep the battery clean. Any evidence of corrosion around the battery posts or terminals should be removed using a solution of household baking sodaand warm water. After the battery terminals are dry, cover them with a light coating of grease.

CHECKING ELECTRIC COOL- ING FANS
WARNING:
The cooling fan is controlled by
engine coolant temperature and may sometimes operate even whenthe engine is not running. Use extreme caution when working near the blades of the cooling fan,so that you are not injured by a rotating fan blade. As the coolant temperature decreases the fan willautomatically shut off. This is a normal condition.
G220B01A-AAT
Checking Engine Cooling Fan
The engine cooling fan should come
on automatically if the engine coolanttemperature is high.
G220C01A-AAT
Checking Condenser Cooling Fan
The condenser cooling fan should
come on automatically whenever the air conditioning is in operation.
