!
G020D01TG-GAT Improper or incomplete service may result in problems. This section gives instructions only for the maintenanceitems that are easy to perform.Several procedures should be done byan authorized Hyundai dealer. NOTE: Improper owner maintenance dur- ing the warranty period may affectwarranty coverage. WARNING:
o Performing maintenance work on a vehicle can be dangerous. Youcan be seriously injured while performing some maintenance procedures. If you lack sufficientknowledge and experience or the proper tools and equipment to do the work, have it done by anauthorized Hyundai dealer.
o Working under the hood with the engine running is dangerous. It becomes even more dangerous when you wear jewelry or looseclothing. These can become en- tangled in moving parts and re- sult ininjury. Therefore, if youmust run the engine while work- ing under the hood, make certain that you remove all jewelry (espe-cially rings, bracelets, watches, and necklaces) and all neckties, scarves, and similar loose cloth-ing before getting near the en- gine or cooling fans.
CHECKING THE ENGINE OIL
G030A02O-GAT
Recommended Oil
Engine oil is essential to the perfor-
mance and service of the engine. It is suggested that you check the oil level at least once a week in normal use and more often if you are on a trip ordriving in severe conditions.
The engine oil quality should meet
the following classification.
API SJ, SL or ABOVE, ILSAC GF-3 or ABOVE G030B01JM

ENGINE OIL CONSUMPTION Function of Engine Oil
Engine oil has the primary function of lubricating and cooling the inside of the engine.
Engine oil consumption It is normal that an engine should consume some engine oil while nor- mal driving. The cause of oil con- sumption in a normal engine are asfollows;
o Engine oil is used to lubricate pis- tons, piston rings and cylinders. A thin film of oil is left on the cylinder wall when a piston moves downwards in the cylinder. High negative pressure generated dur-ing engine operation sucks some of the oil into the combustion cham- ber.This oil with some oil of the cylin-der wall is burned by the high tem-perature combustion gases during the combustion process. o The engine oil consumption is
strongly effected by the viscosity and quality of oil, engine rpm and driving condition etc. The engine oil is more consumed under severedriving conditions such as high speeds and frequent acceleration and deceleration than normal driv-ing condition.

CHECKING AND CHANGING THE ENGINE COOLANT
G050A01TG-AAT
WARNING:
Do not remove the radiator cap
when the engine is hot. When the engine is hot, the engine coolantis under pressure and may erupt through the opening if the cap is removed. You could be seriouslyburned if you do not observe this precaution. Do not remove the radiator cap until the radiator iscool to the touch.
NOTE: It is recommended that the engine coolant should be changed by an authorized Hyundai dealer.

The coolant level can be seen on the
side of the plastic coolant reservoir. The level of the coolant should be between the "L" and "F" lines on the reservoir when the engine is warmwith it at idle . If the level is below the "L" mark, add engine coolant to bring it up to "F". If the level is low, inspectfor coolant leaks and recheck the fluid level frequently. If the level drops again, visit your Hyundai dealer for aninspection and diagnosis of the rea- son.

CAUTION:
o Engine coolant can damage the finish of your car. If you spill engine coolant on the car, wash it off thoroughly with clean water.
o The engine in your vehicle has aluminum engine parts and mustbe protected by an ethylene-gly-col base coolant to prevent corro- sion and freezing. And, do not use the hard water. The hard water can cause engine damage from corrosion, overheat-ing or freezing.
!
G050B01A-AAT
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. Addi-tional corrosion inhibitors or additives should not be used. The cooling sys- tem must be maintained with the cor-rect concentration and type of engine coolant to prevent freezing and corro- sion.
CAUTION:
Never allow the concentration of antifreeze to exceed the 60% level or go below the 35% level, or dam-age to the cooling system may result. For proper concentration when adding or replacing the engine coolant, refer to the following table.

!WARNING:
The cooling fan is controlled by engine coolant temperature and may sometimes operate even when theengine is not running. Use extreme caution when working near the blades of the coolant fan so that youare not injured by a rotating fan blade. As the engine coolant tem- perature decreases, the fan will au-tomatically shut off. This is a nor- mal condition.
SPARK PLUGS
G060A01TG-GAT
G060A01L
Your engine was originally equipped with Iridium-tipped spark plugs (For unleaded only).Iridium-tipped spark plugs will lastlonger than conventional type sparkplugs and can be identified by blue lines on the ceramic shell. NOTE: Do not clean or regap Iridium- tipped spark plugs. G060B01TG-GAT Replacing the Spark Plugs The spark plugs should be changed at the intervals specified in the ve- hicle maintenance schedule in Sec- tion 5 or whenever engine perfor-mance indicates they should be changed. Symptoms that suggest poor spark plug performance include en-gine misfiring under load, loss of fuel economy, poor acceleration, etc. When spark plugs are replaced, al-ways use spark plugs recommended by Hyundai. The use of other spark plugs can result in loss of perfor-mance, radio interference or engine damage. NOTE:
o It is recommended that spark
plugs should be changed by an authorized Hyundai dealer.
o When replacing the spark plugs,
always use the genuine parts rec- ommended.
Unleaded : 1.0~1.1 mm Leaded : 0.7~0.8 mm

Fluid level should be within "HOT"
range 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 fanso 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.
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.
CHECKING THE BRAKES
G120A01A-AAT G120B01A-AAT
Checking the Brake Fluid Level
! 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.
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 paint ifspilled on it and not removed im- mediately.

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 weather when the air conditioning system is not otherwise in use.CHANGING THE AIR CONDITIONER FILTER
B145A01TG-GAT
(For Evaporator and Blower Unit)(If Installed)
The air conditioner filter is located in
the upper portion of the blower fan. It helps to decrease the amount of
pollutants entering the car.
1. Open the glove box.
2. Pull the glove box cylinder to unlock the glove box fixing device. HTG2167
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 yourHyundai dealer.
CAUTION:
Running the air conditioning sys-
tem for extended periods of timewith a low refrigerant level may damage the compressor.
