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.

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.
G110D03Y
Fluid level should be within "HOT" range
3. If the transaxle fluid level is low, use a funnel to add transaxle fluid through 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 other positions -- "R", "N", "D" -- and then return to "N". 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 faras 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

Adding Brake Fluid
WARNING:
Handle brake fluid carefully. It can
damage your vision if it gets into your eyes. Use only DOT 3 or DOT 4 specification fluid from a sealedcontainer. Do not allow the fluid can or reservoir to remain open any longer than required. This willprevent entry of dirt and moisture which can damage the brake sys- tem and cause improper opera- tion.G130A01A-AAT
CHECKING THE CLUTCH FLUID To Check the Clutch Fluid
The clutch fluid level in the master
cylinder should be checked when performing other under hood services.The system should be checked for leakage at the same time.
Check to make certain that the clutch
fluid level is between the "MAX" and"MIN" level markings on the fluid res- ervoir. Fill as required. Fluid loss indi-cates a leak in the clutch system which should be inspected and re- paired immediately. Consult yourHyundai dealer. G130A01L
!
To add brake fluid, first wipe away any dirt then unscrew the fluid reser-voir cap. Slowly pour the recom- mended fluid into the reservoir. Do not overfill. Carefully replace the capon the reservoir and tighten.
G120C02A-AAT Recommended Brake Fluid Use only hydraulic brake fluid con- forming to DOT 3 or DOT 4 specifica- tions in your braking system. Follow the instructions printed on the con-tainer. G120D01A-AAT To Check the Fluid Level
HXG095
The fluid level in the brake fluid reser- voir should be checked periodically. The level should be between the "MIN" and "MAX" marks on the side of thereservoir. If the level is at or below the "MIN" mark, carefully add fluid to bring it up to "MAX". Do not overfill.

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.

CHECKING AND REPLACING FUSES Replacing a Fusible Link
A fusible link will melt if the electrical circuits from the battery are ever over- loaded, thus preventing damage tothe entire wiring harness. (This could be caused by a short in the system drawing too much current.) If thisever happens, have a Hyundai dealer determine the cause, repair the sys- tem and replace the fusible link. Thefusible links are located in a under hood junction box for easy inspec- tion. G200A01L

strument panel junction box you will find a list showing the circuits pro- tected by each fuse.
If any of your car's lights or other
electrical accessories stop working, ablown fuse could be the reason. If the fuse has burned out, you will see that the metal strip inside the fuse hasburned through. If you suspect a blown fuse, follow this procedure:
1. Turn off the ignition and all other switches.
2. Open the instrument panel junction box and examine each fuse. Re- move each fuse by pulling it toward you (a small "fuse puller" tool iscontained in the fuse box to sim- plify this operation).
3. Be sure to check all other fuses even if you find one that appears to have burned out.
HXGS416
4. Replace the blown fuse by press- ing a new fuse of the same rating into place. The fuse should be a snug fit. If it is not, have the fuseclip repaired or replaced by a Hyundai dealer. If you do not have a spare fuse, you may be able toborrow a fuse of the same or lower rating from an accessory you can temporarily get along without (theradio or cigarette lighter, for ex- ample). Always remember to re- place the borrowed fuse.
G200B01Y-GAT Replacing Accessory Fuse
G200B01L
The instrument panel junction box for the lights and other electrical acces-sories will be found low on the dash- board on the driver's side. Inside in- CAUTION:
When replacing a fusible link, never
use anything but a new fusible link with the same or lower amper- age rating. Never use a piece of wire or a higher-rated fusible link.This could result in serious dam- age and create a fire hazard.
