SPARK PLUGSG060B01JM-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:o When replacing the spark plug, genuine
Hyundai replacement parts are recom-
mended.
o It is recommended that the spark plug
should be changed by an authorized
Hyundai dealer. (2.7 L)
o Do not clean or regap spark plugs.
G060C01JM-AATChanging the Spark PlugsYou will find it easier to change spark plugs if the
engine is cold. Always change one spark plug
at a time. This helps avoid getting the wires
mixed up.
1. Remove the center cover (2.0L) on the
engine rocker cover.
2. Using a clean cloth, remove any dirt that has
accumulated around the base of the spark
plug so it cannot fall into the cylinder when the
spark plug is removed.
3. To remove the spark plug cable, pull straight
up on the insulated connector, not the cable.
Pulling on the cable may damage the carbon
core conductor.

CHANGING THE AIR CLEANER
FILTERG070A01E-AATTo change the filter, unsnap the clips around the
cover. When this is done, the cover can be lifted
off, the old filter removed and the new filter put
in its place. Genuine Hyundai Replacement
Parts are recommended.
CAUTION:
o Operating your vehicle without a proper
air 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-
age to the air cleaner filter.
!
6. To install the new spark plug, guide the
socket down over the spark plug, being
careful not to damage the ceramic insulator.NOTE:Spark plugs should be tightened to speci-
fication. Over-tightening can damage the
threads in the aluminum cylinder head.
Also, leaving them too loose can cause the
spark plug to get very hot and possibly
result in damage to the engine.
7. Replace the cable by pushing the insulated
connector directly down onto the electrode.
Check to be sure it has snapped into place
and can't fall off.
!
WARNING:
It is recommended that the engine be cool
or cold when changing the spark plugs. If
the engine is hot, you could burn yourself
on the insulated connector, the spark plug
or the engine itself.
4. When preparing to remove the old spark
plug, guide the socket down over the spark
plug, being careful not to damage the ce-
ramic insulator.
5. To remove the old spark plug, turn the
wrench handle in a counterclockwise direc-
tion.

G210B03A-AATChecking the BatteryKeep the battery clean. Any evidence of corro-
sion around the battery posts or terminals
should be removed using a solution of house-
hold baking soda and warm water. After the
battery terminals are dry, cover them with a light
coating of grease. 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 assistance
as soon as possible. While you are being
driven to get medical assistance, continue to
rinse your eyes by using a sponge or soft
cloth saturated with water.
o If you swallow battery fluid, drink a large
quantity of water or milk followed by milk of
magnesia, eat a raw egg or drink vegetable
oil. Get medical assistance as soon as
possible.
While batteries are being charged (either by a
battery charger or by the vehicle's generator),
they produce explosive gases. Always ob-
serve these warnings to prevent injuries from
occurring:
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.
