conditions, more frequent oil and filter changes
are required.

Fuel Filter Fuel FilterFuel Filter Fuel Filter
Fuel FilterA clogged filter can limit the speed at which the
vehicle may be driven, damage the emission
system and cause hard starting. If an exces-
sive amount of foreign matter accumulates in
the fuel tank, the filter may require replace-
ment more frequently.
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
heat and/or mechanical damage. Hard and
brittle rubber, cracking, tears, cuts, abra-
sions, and excessive swelling indicate dete-
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.

Adding Oil
Wait a minute, then remove the dipstick, wipe it
off, fully reinsert the dipstick and withdraw it
again. Then note the highest level the oil has
reached on the dipstick. It should be between
the upper ("FULL") and lower ("LOW") range.
If the oil level is close to or below the "LOW"
mark, add oil until it reaches the "FULL" mark.
To add oil:
1. Remove the oil filler cap by turning it counter-
clockwise.
2. Add oil, then check the level again. Do not
overfill.
3. Replace the cap by turning it clockwise.
The distance between the "FULL" and "LOW"
marks is equal to about 1 quart of oil.

CHANGING THE OIL AND FILTER
The engine oil and filter should be changed at
those intervals specified in the maintenance
schedule in Section 5. If the car is being driven
in severe conditions, more frequent oil and filter
changes are required.
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 lowest
mark. Turn the engine off and place the gear
selector lever in "P" (automatic) or reverse
gear (manual transaxle). Set the parking
brake.
2. Open the hood and remove the engine oil
filler cap.
