coolant temperature and may sometimes
operate even when the engine is not run-
ning. Use extreme caution when working
near the blades of the coolant fan so that
you are not injured by a rotating fan blade.
As the engine coolant temperature de-
creases, the fan will automatically shut off.

SPARK PLUGSG060A01NF-AAT
G060A01LYour engine was originally equipped with Iri-
dium-tipped spark plugs.
Iridium-tipped spark plugs will last longer than
conventional type spark plugs and can be
identified by blue lines on the ceramic shell.NOTE:Do not clean or regap Iridium-tipped spark
plugs.
G060B01NF-AATReplacing the Spark PlugsThe spark plugs should be changed at the
intervals specified in the vehicle maintenance
schedule in Section 5 or whenever engine
performance indicates they should be changed.
Symptoms that suggest poor spark plug perfor-
mance include engine misfiring under load, loss
of fuel economy, poor acceleration, etc. When
spark plugs are replaced, always 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:When replacing the spark plugs, always use
the genuine parts recommended.Recommended Spark Plugs:
0.039 ~ 0.043 in.

get very hot and possibly result in damage
to the engine.

o Operating your vehicle without using a
proper air cleaner filter in place can result
in excessive engine wear.
o When removing the air cleaner filter, be
careful that dust or dirt does not enter
the air intake. These may result in dam-

Park the car on level ground with the engine off.
1. Using a wrench of the correct size, loosen
the oil filler plug by turning it counterclock-
wise and remove it with your fingers.
2. Use your finger to feel inside the hole. The oil
level should be at its bottom edge. If it is not,
check for leaks before adding oil. To refill the
transaxle or bring the oil level up, add oil
slowly until it reaches the proper level. Do not
overfill.
3. Replace the plug and washer, screw it in with
your fingers and then tighten securely with
the wrench.
