11CHANGING THE OIL AND FILTER
!
G040A04FC-GAT
Gasoline Engine
G040A03EThe engine oil and filter should be
changed at those intervals specified in the maintenance schedule in Sec- tion 5. If the vehicle is being driven in severe conditions, more frequent oiland filter changes are required.
The procedure for changing the oil
and filter is as follows:
1. Park the vehicle on level ground
and set the parking brake. Start the engine and let it warm up until the needle on the coolant temperature gauge moves above the lowestmark. Turn the engine off and place the gear selector lever in "P" (auto- matic) or reverse gear (manualtransaxle).
2. Open the hood and remove the engine oil filler cap.
3. Slide underneath the car and loosen
the drain plug by turning it counter-clockwise with a wrench of the proper size. Be sure that a drain pan is in position to catch the oil asit drains out, then remove the drain plug. WARNING:
Be very careful when draining the engine oil as it may be hot enough to burn you!
4. When the oil has stopped draining, replace the drain plug using a new gasket and retighten by turning it clockwise.

5. Remove the oil filter. You should be able to unscrew the filter with your hands. (If your hands are slip- pery, try to use a cloth between your hands and the filter to giveyourself a better grip.) A certain amount of oil will come out when you remove the filter, so be sure tohave your drain pan in place un- derneath it. kgf.m

The procedure for changing the oil
and filter is as follows:
1. Park the car on level ground and
set the parking brake. Start the engine and let it warm up until the needle on the coolant temperature gauge moves above the lowestmark.
10. Shut off the engine and recheck
the oil level.
NOTE: Always dispose of used engine oil in an environmentally acceptable manner. It is suggested that it be placed in a sealed container andtaken to a service station for maybe reclaimation. Do not pour the oil on the ground or put it in with thehousehold trash.
6. Install a new oil filter in accordance
with the instructions on the cartonor on the filter itself. Do not over- tighten.
Oil filter tightening torque: 1.2~1.6kgf.m Be sure that the mounting surfaceon the engine is clean and that the old gasket is removed completely. Lubricate the new gasket on thefilter with clean engine oil before installation.
7. Remove the engine oil level dip- stick.
8. Refill the crankcase with the rec- ommended engine oil. Refer tothe specification in chapter 9 for engine oil capacity. WARNING:
Used motor oil may cause irrita-
tion or cancer of the skin if left incontact with the skin for prolonged periods of time. Wash your hands thoroughly with soap and warmwater as soon as possible after handling used oil.

! CAUTION:
Slowly pour the recommended oil into a funnel. Do not overfill not to damage the engine.
9. Start the engine and check to be sure no oil is leaking from the drain plug or oil filter.

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.
WARNING:
Used motor oil may cause irrita- tion or cancer of the skin if left in contact with the skin for prolongedperiods of time. Wash your hands thoroughly with soap and warm water as soon as possible afterhandling used oil.

Water
65% 60%50%40%

Use a high quality ethylene-glycol coolant in a 50/50 mix with water. The engine coolant should be compatiblewith 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. Never allow the concentration of antifreeze to exceed the 60% level or go below the 35% level, or damage tothe cooling system may result. For proper concentration when adding or replacing the engine coolant, refer tothe following table. G050C02E
Diesel engine
G050C01A-GAT
To Check the Coolant Level
The coolant level can be seen on the side of the plastic coolant reservoir. The level of the coolant should bebetween the "L" and "F" lines on the reservoir when the engine is cold. If the level is below the "L" mark, addengine coolant to bring it up between "L" and "F". If the level is low, inspect for coolant leaks and recheck thefluid level frequently. If the level drops again, visit your Hyundai dealer for an inspection and diagnosis of the rea-son.

4. Turn the radiator cap counterclock-
wise without pressing down on it, until it stops. This relieves any pres- sure remaining in the cooling sys- tem. And remove the radiator cap by pushing down and turning coun-terclockwise.Fill the radiator with clean deminer-alized or distilled water. Continueto add clean demineralized or dis- tilled water in small quantities until the fluid level stays up in the radia-tor neck. G050D03E

To Change the Coolant
The coolant should be changed at
those intervals specified in the ve- hicle maintenance schedule in Sec- tion 5.
! CAUTION:
Engine coolant can damage the
finish of your car. If you spill en- gine coolant on the car, wash it off thoroughly with clean water.
1. Park the car on level ground, set the parking brake and remove the radia- tor cap when cool.
2. Be sure your drain receptacle is in
place. Open the drain cock on theradiator. Allow all the engine cool- ant to drain from the cooling sys- tem, then securely close the draincock.
3. Check Section 9 for the capacity of the cooling system in your car.Then, following the manufacturer's directions on the engine coolant container, add the appropriatequantity of coolant to the radiator.
!WARNING:
Remove the radiator cap when the
radiator is cool. 5. Start the engine, top off the radiator
with water and then add engine coolant to the reservoir until thelevel is between "L" and "F".
6. Replace the radiator and reservoir
caps and check to be sure the draincocks are fully closed and not leak- ing.

SPARK PLUGS
G060A01L
G060B02S-GAT
REPLACING THE SPARK PLUGS (Gasoline Engine)
The spark plugs should be changed
at the intervals specified in the ve- hicle maintenances 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.Unleaded: 1.0 ~ 1.1 mm (0.039 ~ 0.043 in.) Leaded: 0.7 ~ 0.8 mm (0.028 ~ 0.032 in.)
NOTE: When replacing the spark plugs, genuine Hyundai replacement partsare recommended. Recommended Spark Plugs:

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 cooling fan so thatyou are 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.

CHECKING THE BRAKES
G120A01A-AAT
! CAUTION:
Because brakes are essential to
the safe operation of the car, it is suggested that they be checked and inspected by your Hyundai dealer. The brakes should bechecked and inspected for wear at those intervals specified in the vehicle maintenance schedule inSection 5.
WARNING (Diesel only):
Never work on injection system
with engine running or within 30 seconds after shutting off engine. High pressure pump, rail, injec-tors and high pressure pipes are subject to high pressure even af- ter the engine stopped. The fuel jetproduced by fuel leaks may cause serious injury, if it touch the body. People using pacemakers shouldnot move than 30cm closer to the ECU or wiring harness within the engine room while engine is run-ning, since the high currents in the Common Rail system produce considerable magnetic fields.
WARNING:
The cooling fan is controlled byengine coolant temperature and may sometimes operate even when the engine is not running. Useextreme caution when working near the blades of the cooling fan so that you are not injured by arotating fan blade. As the engine coolant temperature decreases, the fan will automatically shut off. Thisis a normal condition.

Fluid level should be within this 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.
