● To prevent serious burns:
Avoid contact with hot metal parts.
Do not remove the radiator cap when the engine is hot.
● Dispose of drained oil or the solvent used for cleaning parts in
an appropriate manner.
● Do not attempt to top off the fuel tank after the fuel pump nozzle
shuts off automatically.
Continued refueling may cause fuel overflow, resulting in fuel
spray and possibly a fire.
● Clean all disassembled parts in the designated liquid or solvent
prior to inspection or assembly.
● 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 components which use microcomputers (such as ECM).
Static electricity may damage internal electronic components.
● After disconnecting vacuum or air hoses, attach 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 tools 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 cov-
ers.
Take caution that keys, buckles or buttons do not scratch paint.
WARNING:
To prevent ECM from storing the diagnostic trouble 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 and AT sections.
Precautions for Three Way Catalyst
BAS0002I
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
necessary.
● 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.
Precautions for Fuel
BAS0002J
GASOLINE ENGINE (REGULAR GASOLINE)
● Three way catalyst equipped models ... use unleaded gasoline with an octane rating of at least 91 RON
(research octane number).
