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.
HKSOM120
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.

27AIR CONDITIONING CARE
G140A01A-AAT
Keeping the Condenser Clean
The air conditioning condenser (and engine radiator) should be checked periodically for accumulation of dirt, dead insects, leaves, etc. These caninterfere with maximum cooling effi- ciency. When removing such accu- mulations, brush or hose them awaycarefully to avoid bending the cooling fans.
G140B01A-AAT
Checking the Air Conditioning Operation
1. Start the engine and let it run at a
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 weather when 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 maydamage the compressor.
! G140D01S-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, pressdown on the belt halfway between theengine crankshaft and compressor pulleys. Pressing with your finger, you should not be able to deflect this beltanymore than 8.0 mm. If you have the instruments to check it with a force of 98N (22 lb.), the deflectionshould be approx. 8.0 mm (0.315 in.). If the belt is too loose, have it ad- justed by your Hyundai dealer.

CHECKING ELECTRIC COOLING FANS
G220A01A-AAT
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 engine coolant temperature decreases thefan will automatically shut off. This is a normal condition.
o When lifting a plastic-cased bat-
tery, excessive pressure on the case may cause battery acid toleak, resulting in personal injury. Lift with a battery carrier or with your hands on opposite corners.
o Never attempt to charge the bat- tery when the battery cables areconnected.
o The electrical ignition system works with high voltage. Never touch these components with the engine running or the ignition switched on.
The power steering fluid level should
be checked regularly.
