Recommended Engine Coolant
Use a high quality ethylene-glycol coolant in a
50/50 mix with water. The engine coolant should be compatible with aluminum engine parts. Ad-ditional corrosion inhibitors or additives shouldnot be used. The cooling system must be main-tained with the correct concentration and typeof engine coolant to prevent freezing and corro-sion. Never allow the concentration of antifreeze to exceed the 60% level or go below the 35% levelor damage to the coolant system may result. Forproper concentration when adding or replacingthe coolant, refer to the following table.
35% 40%50%60% G050C01A-AAT
To Check the Coolant Level
The coolant level can be seen on the side of the plastic coolant reservoir. The level of the cool-ant should be between the "LOW" and "FULL"lines on the reservoir when the engine is cold.If the level is below the "LOW" mark, addengine coolant to bring it up between "LOW"and "FULL". If the level is low, inspect forcoolant leaks and recheck the fluid level fre-quently. If the level drops again, visit yourHyundai dealer for an inspection and diagnosisof the reason. G050D02A-AAT
To Change the Engine Coolant
The engine coolant should be changed at thoseintervals specified in the vehicle maintenanceschedule in Section 5. CAUTION: Engine coolant can damage the finish of your car. If you spill engine coolant on thecar, wash it off thoroughly with clean water.
1. Park the car on level ground, set the parking brake and remove the radiator cap whencool.
2. Be sure your drain receptacle is in place. Open the drain cock on the radiator. Allowall the engine coolant to drain from thecooling system, then securely close the draincock.
3. Check Section 9 for the capacity of the cooling system in your car. Then, followingthe manufacturer's directions on the enginecoolant container, add the appropriate quan-tity of engine coolant to the radiator.

4. Turn the radiator cap counterclockwise with-out pressing down on it, until it stops. This relieves any pressure remaining in the cool-ing system. And remove the radiator cap bypushing down and turning counterclockwise. Now fill the radiator with clean demineral- ized or distilled water. Continue to add cleandemineralized or distilled water in small quan-tities until the fluid level stays up in theradiator neck.SSA6060A

REPLACING THE SPARK PLUGS
The spark plugs should be changed at the
intervals specified in the vehicle maintenance schedule in Section 5 or whenever engine per-formance indicates they should be changed.Symptoms that suggest poor spark plug perfor-mance include engine misfiring under load, lossof fuel economy, poor acceleration, etc. Whenspark plugs are replaced, always use sparkplugs recommended by Hyundai. The use ofother spark plugs can result in loss of perfor-mance, radio interference or engine damage.
NOTE: When replacing the spark plug, always use
the genuine parts recommended.

5. Start the engine, top off the radiator with water and then add engine coolant to the reservoir until the level is between "LOW"and "FULL".
6. Replace the radiator and reservoir caps and check to be sure the drain cocks are fullyclosed and not leaking.
WARNING: The cooling fan is controlled by engine cool-
ant temperature and may sometimes oper- ate even when the engine is not running.Use extreme caution when working near theblades of the cooling fan so that you are notinjured by a rotating fan blade. As the en-gine coolant temperature decreases, the fanwill automatically shut off. This is a normalcondition.

Recommended Brake Fluid
Use only hydraulic brake fluid conforming to
DOT 3 or DOT 4 specifications in your braking G120A01A-AAT
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 yourHyundai dealer. The brakes should bechecked and inspected for wear at thoseintervals specified in the vehicle mainte-nance schedule in Section 5.

Checking the Brake Fluid Level
WARNING: Use caution when handling brake fluid. It
can damage your vision if it gets into your eyes. It will also damage your vehicle's paintif spilled on it and not removed immediately.

To Check the Automatic Transaxle Fluid Level
Park the car on level ground with the parking
brake engaged. When the transaxle fluid level is checked, the transaxle fluid should be atnormal operating temperature and the engineidling. While the engine is idling, apply the brakes andmove the gear selector lever from "P" to eachof its other positions — "R", "N", "D", "2", "L" —and then return to "N" or "P" with the engine stillidling:
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, thenremove it again. Now check the fluid level onthe dipstick. It should be in the "HOT" rangeon the dipstick.
Fluid level should be within this range
3. If the transaxle fluid level is low, use a funnel to add transaxle fluid through the dipsticktube until the level reaches the "HOT" range.Do not overfill.

Checking the Air Conditioning Opera- tion
1. Start the engine and let it run at a fast idle for
several minutes with the air conditioning set at the maximum cold setting.
2. If the air coming out of the in-dash vents is not cold, have the air conditioning systeminspected by your Hyundai dealer.
CAUTION: Running the air conditioning system for ex- tended periods of time with a low refrigerantlevel may damage the compressor.
When the air conditioning is being used regu-larly, the compressor drive belt tension shouldbe checked at least once a month. To check the drive belt tension, press down on the belt halfway between the engine crankshaftand compressor pulleys. Pressing with yourfinger, you should not be able to deflect this belt
anymore than 5 - 5.5 mm. If you have theinstruments to check it with a force of 98N (22lb.), the deflection should be approx. 5 - 5.5(0.197 - 0.217 inches). If the belt is too loose,have it adjusted by your Hyundai dealer.
G120D01A-AAT
To Check the Fluid Level The fluid level in the brake fluid reservoir should
be checked periodically. The level should bebetween the "MIN" and "MAX" marks on theside of the reservoir. If the level is at or belowthe "MIN" mark, carefully add fluid to bring it upto "MAX". Do not overfill.
G120E02A-AAT
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 asealed container. Do not allow the fluid canor reservoir to remain open any longer thanrequired. This will prevent entry of dirt and moisture which can damage the brake sys-tem and cause improper operation.
To add brake fluid, first wipe away any dirt then
unscrew the fluid reservoir cap. Slowly pour therecommended fluid into the reservoir. Do notoverfill. Carefully replace the cap on the reser-voir and tighten.

POWER STEERING FLUID LEVEL
The power steering fluid level should be checked
regularly.
To check the power steering fluid level, be sure
the ignition is "OFF", then check to make cer- tain that the power steering fluid level is be-tween the "MAX" and "MIN" level markings onthe fluid reservoir.
NOTE: Grinding noise from the power steering
pump may be heard immediately after the engine is started in extremely cold condi-
tions (below -20°C). If the noise stops dur-ing warm up, there is no abnormal functionin the system. This is due to a power steer-ing fluid characteristic in extremely coldconditions.
G230A01X
The fluid in the battery contains a strong solu-
tion of sulfuric acid, which is poisonous and highly corrosive. Be careful not to spill it onyourself or the car. If you do spill battery fluid onyourself, immediately do the following:
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 get medical assistanceas soon as possible. While you are beingdriven to get medical assistance, continueto rinse your eyes by using a sponge or softcloth saturated with water.
o If you swallow battery fluid, drink a large quantity of water or milk followed by milk ofmagnesia, eat a raw egg or drink vegetableoil. Get medical assistance as soon aspossible.
While batteries are being charged (either by abattery charger or by the vehicle's alternator),they produce explosive gases. Always observethese warnings to prevent injuries from occur-ring:
o Charge batteries only in a well ventilated 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 corro-
sion around the battery posts or terminals should be removed using a solution of household bak-ing soda and warm water. After the batteryterminals are dry, cover them with a light coat-ing of grease.
