GENERAL MAINTENANCE
UNDER THE HOOD AND VEHICLE
The maintenance items listed here should be checked periodically (e.g. each time you check the engine oil or refuel).
SeatsCheck seat position controls such as seat adjusters, seatback recliner, etc. to
make sure they operate smoothly and that all latches lock securely in every po-
sition. Check that the head restraints move up and down smoothly and that the
locks (if equipped) hold securely in all latched positions. Check that the latches
lock securely for folding-down rear seatbacks. —
Seat belts Check that all parts of the seat belt system (e.g. buckles, anchors, adjusters and
retractors) operate properly and smoothly and are installed securely. Check the
belt webbing for cuts, fraying, wear or damage. MA-43
Accelerator pedal
Check the pedal for smooth operation and make sure the pedal does not catch
or require uneven effort. Keep the floor mats away from the pedal. —
Brakes Check that the brake does not pull the vehicle to one side when applied. —
Brake pedal and
booster Check the pedal for smooth operation and make sure it has the proper distance
under it when depressed fully. Check the brake booster function. Be sure to keep
floor mats away from the pedal. BR-9
Clutch pedal
Make sure the pedal operates smoothly and check that it has the proper free play. CL-5
Parking brakeCheck that the lever or pedal has the proper travel and make sure that the vehicle
is held securely on a fairly steep hill when only the parking brake is applied. PB-4
CVT "P" (Park) posi-
tion mechanismOn a fairly steep hill check that the vehicle is held securely with the shift selector
in the "P" (PARK) position without applying any brakes.

Windshield washer
fluid Check that there is adequate fluid in the tank.
—
Engine coolant level Check the coolant level when the engine is cold. CO-8
Radiator and hosesCheck the front of the radiator and clean off any dirt, insects, leaves, etc., that
may have accumulated. Make sure the radiator hoses have no cracks, deforma-
tion, deterioration or loose connections. CO-12
Brake and clutch fluid
levelsMake sure that the brake and clutch fluid levels are between the “MAX” and “MIN”
lines on the reservoirs. BR-12
CL-7
Battery
Check the fluid level in each cell. It should be between the “MAX” and “MIN” lines.
Vehicles operated in high temperatures or under severe conditions require fre-
quent checks of the battery fluid level. PG-61
Engine drive belts
Make sure that no belt is frayed, worn, cracked or oily. MA-14
Engine oil levelCheck the level on the oil level gauge after parking the vehicle on a level spot and
turning off the engine. MA-20
Exhaust system
Make sure there are no loose supports, cracks or holes. If the sound of the ex-
haust seems unusual or there is a smell of exhaust fumes, immediately locate the
trouble and correct it. MA-26
Underbody
The underbody is frequently exposed to corrosive substances such as those
used on icy roads or to control dust. It is very important to remove these sub-
stances, otherwise rust will form on the floor pan, frame, fuel lines and around the
exhaust system. At the end of winter, the underbody should be thoroughly
flushed with plain water, being careful to clean those areas where mud and dirt
can easily accumulate. —
Fluid leaks Check under the vehicle for fuel, oil, water or other fluid leaks after the vehicle
has been parked for a while. Water dripping from the air conditioner after use is
normal. If you should notice any leaks or gasoline fumes are evident, check for
the cause and correct it immediately. —

1. Install radiator drain plug and reservoir tank, if removed.
CAUTION:
Be sure to clean drain plug and install with new O-ring.
2. If water drain plugs on cylinder block were removed, close and tighten them. Refer to EM-93, "
Exploded
View".
3. Remove air duct from between air cleaner case and electric throttle control actuator. Refer to EM-26,
"Removal and Installation".
4. Disconnect heater hose (1) at location ( ) as shown. • Position heater hose as high as possible.
: Front
5. Fill radiator until engine coolant flows out of the disconnected heater hose and then reconnect the heater
hose.
6. Finish filling the engine and reservoir tank with water and reinstall the radiator cap.
7. Install air duct in between air cleaner case and electric throttle control actuator. Refer to EM-26, "
Removal
and Installation".
8. Run the engine and warm it up to normal operating temperature.
9. Rev the engine two or three times under no-load.
10. Stop the engine and wait until it cools down.
11. Drain water from the system. Refer to MA-16, "
ENGINE COOLANT : Draining Engine Coolant".
12. Repeat steps 1 through 11 until clear water begins to drain from radiator.
FUEL LINES
FUEL LINES : InspectionINFOID:0000000012432256

Installation is in the reverse order of removal.
NOTE:
Check that the air cleaner filter is securely placed in the air cleaner body.

ENGINE OIL LEVEL
NOTE:
Before starting engine, position the vehicle so that it is level and check the engine oil level. If engine is already
started, stop it and allow 10 minutes before checking.
1. Pull out oil level gauge and wipe it clean.
2. Insert oil level gauge and check that the engine oil level is withinthe range (A) as shown.
3. If it is out of range, adjust it.
ENGINE OIL APPEARANCE
• Check engine oil for white milky appearance or excessive contamination.
• If engine oil becomes turbid and white, it is highl y probable that it is contaminated with engine coolant.
Repair or replace damaged parts.
ENGINE OIL LEAKS
Check for engine oil leaks around the following areas:
• Oil pan (upper and lower)
• Oil pan drain plug
• Oil pressure sensor
• Oil filter
• Oil cooler
• Oil level sensor
• Engine oil temperature sensor
• Intake valve timing control solenoid valve
• Exhaust valve timing control solenoid valve
• Mating surface between front cover and rocker cover
• Mating surface between cylinder block and cylinder head
• Mating surface between cylinder head and rocker cover
• Crankshaft oil seals (front and rear)
• Front cover
