To Keep Locks from FreezingTo keep the locks from freezing, squirt an ap-
proved de-icer fluid or glycerine into the key
opening. If a lock is covered with ice, squirt it with
an approved de-icing fluid to remove the ice. If
the lock is frozen internally, you may be able to
thaw it out by using a heated key. Handle the
heated key with care to avoid burning the fingers.

Don't Let Your Parking Brake FreezeUnder some conditions your parking brake can
freeze in the engaged position. This is most likely
to happen when there is an accumulation of snow
or ice around or near the rear brakes or if the
brakes are wet. If there is a risk the parking brake
may freeze, apply it only temporarily while you
put the gear selector lever in "P" (automatic) or in
first or reverse gear (manual transaxle) and
block the rear wheels so the car cannot roll. Then
release the parking brake.

After installing a new filter, run the engine for
several minutes, and check for leaks at the
connections. Fuel filters should be installed by
trained technicians.

Inspect the surface of hoses for evidence of

rioration. Particular attention should be paid to
examine those hose surfaces nearest to high
heat sources, such as the exhaust manifold.
Inspect the hose routing to assure that the
hoses do not come in contact with any heat
source, sharp edges or moving component
which might cause heat damage or mechani-
cal wear. Inspect all hose connections, such
as clamps and couplings, to make sure they
are secure, and that no leaks are present.
Hoses should be replaced immediately if there
is any evidence of deterioration or damage.

Replacing the Spark PlugsThe spark plugs should be changed at the
intervals specified in the vehicle maintenance
schedule in Section 5 or whenever engine per-
formance 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-

plug, guide the socket down over the spark
plug, being careful not to damage the ce-

5. To remove the spark plug, turn the wrench
handle in a counterclockwise direction.
6. To replace the new spark plug, guide the
socket down over the spark plug, being
careful not to damage the ceramic insulator.You 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 on the engine
rocker cover.
2. Using a clean cloth, remove any dirt that has
accumulated around 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
