PRECAUTIONS
• Replace oil seals, gaskets, packings, O-rings, locking washers, cotter pins, self-locking nuts, etc. with new
ones.
• Replace inner and outer races of tapered roller bearings and needle bearings as a set.
• Arrange the disassembled parts in accordance with their assembled locations and sequence.
• Do not touch the terminals of electrical com ponents which use microcomputers (such as ECM).
Static electricity may damage internal electronic components.
• After disconnecting vacuum or air hoses, atta ch a tag to indicate the proper connection.
• Use only the fluids and lubricants specified in this manual.
• Use approved bonding agent, sealants or their equivalents when required.
• Use hand tools, power tools (disassembly only) and recommended special tools where specified for safe and efficient service repairs.
• When repairing the fuel, oil, water, vacuum or exhaust systems, check all affected lines for leaks.
• Before servicing the vehicle: Protect fenders, upholstery and carpeting with appropriate covers.
Take caution that keys, buckles or buttons do not scratch paint.
WARNING:
To prevent ECM from storing the diagnostic tro uble codes, do not carelessly disconnect the harness
connectors which are related to the engine control system and TCM (transmission control module)
system. The connectors should be disconnected only when working according to the WORK FLOW of
TROUBLE DIAGNOSES in EC, CVT, and AT sections.
Precaution for Three Way CatalystINFOID:0000000005929712
If a large amount of unburned fuel flows into the catalyst , the catalyst temperature will be excessively high. To
prevent this, follow the instructions.
• Use unleaded gasoline only. Leaded gasoline will seriously damage the three way catalyst.
• When checking for ignition spark or measuring engine compression, make tests quickly and only when nec- essary.
• Do not run engine when the fuel tank level is low, otherwise the engine may misfire, causing damage to the
catalyst.
Do not place the vehicle on flammable material. Keep flammable material off the exhaust pipe and the three
way catalyst.
Precaution for Fuel (Unleade d Regular Gasoline Recommended)INFOID:0000000005929713
Use unleaded regular gasoline with an octane rating of at least 87 AKI (Anti-Knock Index) number (Research
octane number 91).
CAUTION:
Do not use leaded gasoline. Using leaded gasoline will damage the three way catalyst. Do not use E-85
fuel (85% fuel ethanol, 15% unleaded gasoline) unless the vehicle is specifically designed for E-85 fuel

• Before installing a connector, make sure the terminal is not bent or damaged, and then correctly connect it.
When installing a connector by tightening bolts, fix it by tightening
the mounting bolt until the painted projection of the connector
becomes even with the surface.
• For removal of the lever type connector, pull the lever up to the direction pointed to by the arrow A in the figure, and then remove
the connector.
• For installation of the lever type connector, pull down the lever to the direction pointed by the arrow B in the figure, and then push
the connector until a clicking noise is heard.
• Do not apply excessive shock to the control unit by dropping or hit- ting it.
• Be careful to prevent condensation in the control unit due to rapid
temperature changes and do not let water or rain get on it. If water
is found in the control unit, dry it fully and then install it in the vehi-
cle.
• Be careful not to let oil to get on the control unit connector.
• Avoid cleaning the control unit with volatile oil.
• Do not disassemble the control unit, and do not remove the upper and lower covers.

• The refill capacity depends on the engine oi l temperature and drain time. Use these specifica-
tions for reference only.
• Always use oil level gauge to determine the pr oper amount of engine oil in the engine.
3. Warm up engine and check area around drain plug and oil filter for engine oil leakage.
4. Stop engine and wait for 10 minutes.

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).
Seat beltsCheck 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-49
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. —
Clutch pedal Make sure the pedal operates smoothly and check that it has the proper free play. CL-6
BrakesCheck 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-6
and
BR-20
Parking brake Check that the lever 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-5
Automatic transaxle
“Park” mechanismCheck that the lock release button on the selector lever operates properly and
smoothly. On a fairly steep hill check that the vehicle is held securely with the se-
lector lever in the “P” position without applying any brakes. —

Exhaust system
Make sure there are no loose supports, cracks or holes. If the sound of the exhaust
seems unusual or there is a smell of exhaust fumes, immediately locate the trouble
and correct it. MA-37, "EXHAUST SYS-

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 substances, oth-
erwise rust will form on the floor pan, frame, fuel lines and around the exhaust sys-
tem. 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 accumu-
late. —
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. —
