connectors until they snap.

ELECTRICAL COMPONENTS1. When installing any of the vehicle parts, be careful not to
pinch or damage any of the wiring harnesses.
2. Sensors, relays, etc.,are sensitive to strong impacts.
Handle them with care so that they are not dropped or
mishandled.
,**3. The electronic parts used for relays, etc., are sensitive to
heat. If any service which causes a temperature of
80°C
(176°F) or more is performed, remove the part or parts in
question before carrying out the service.
FUSES AND FUSIBLE LINKS
1.If a blown-out fuse is to be replaced, be sure to use only a
fuse of the specified capacity. If a fuse of a capacity larger
than that specified is used, parts may be damaged and thecircuit may not be protected adequately.
Caution
1.If a fuse is blown-out, be sure to eliminate the causeof the problem before installing a new fuse.
;i2.Check the condition of fuse holders. If rust or dirt isfound, clean metal parts with a fine-grained sand-
paper until proper metal-to-metal contact is
made.Poor contact of any fuse holder will
often lead tovoltage drop or heating in the circuit
and colildresult in improper circuit operation.

LUBRICATION AND MAINTENANCE - Maintenance Service
MAINTENANCE SERVICE1. FUEL SYSTEM (Tank, Lines,
Connect%ms and
Fuel Filler Cap) (Check for
leaks)/2. FUEL
HOSE (Check for leaks or
damage)1 NSOSAGtib1. Check for damage or leakage in the fuet
lines and
connections and looseness of the fuel
fi!:ler cap.
2.Inspect the surface of fuel hoses for heat and mecha-
nical damage. Hard and brittle rubber, cracking, check-
ing, tears, cuts, abrasions and excessive swelling
indicate deterioration of the rubber.
3. If the fabric casing of the rubber hose is exposed by
cracks and abrasions in the fuel system, the hoses
should be changed.
3. AIR CLEANER ELEMENT (Replace)
NOOSAKBbThe air cleaner element will become dirty and loaded with
dust during use, and the filtering effect will be substantially
reduced. Replace it with a new one.
<1.8L Engine, 2.0L DOHC Engine (Non-Turbo)>
(1) Disconnect the air-flow sensor connector.
(2) Remove the air intake hose.
(3) Unclamp the air cleaner cover.
(4) Push the air intake hose backward, and remove the air
cleaner cover.
Caution
Care must be taken when removing the air cleaner
cover, because the air-flow sensor is ‘attached.
(5) Take out the air cleaner element.
<2.0L DOHC Engine (Turbo)>
(1) Disconnect the air-flow sensor connector.
(2) Disconnect the boost hose.
(3) Disconnect the solenoid valve with hoses.
(4) Disconnect the air intake hose.
(5) Remove the air cleaner retaining bolts.
(6) Remove the air cleaner assembly.
(7) Unclamp the air cleaner cover.
Caution
Care must be taken when removing the air cleaner
cover, because the air-flow sensor is attached.
(8) Take out the air cleaner element.
