PRECAUTIONS
GI-5
lUse only the fluids and lubricants specified in this manual.
lUse approved bonding agent, sealants or their equivalents when required.
lUse tools and recommended special tools where specified for safe and efficient service repairs.
lWhen repairing the fuel, oil, water, vacuum or exhaust systems, check all affected lines for leaks.
lBefore servicing the vehicle:
Protect fenders, upholstery and carpeting with appropriate cov-
ers.
Take caution that keys, buckles or buttons do not scratch paint.
WA RN ING:
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 All Mode 4´4 SystemEAS000GQ
Even if the 2WD mode is selected, the All mode 4´4 system occasionally changes from 2WD to 4WD auto-
matically depending on the driving conditions.
When spinning the front wheels by running the engine with the front wheels jacked up or mounted on the free
rollers / or a chassis dynamometer, be careful because the vehicle may suddenly move due to the driving
force from the rear wheels.
To avoid personal injury and vehicle damage, use one of the following methods when working with the front
wheels drive force and spinning freely.
lRemove the propeller shaft.
lUse free rollers / chassis dynamometer designed for 4WD vehicles.
Precautions for Three Way CatalystEAS000FR
If a large amount of unburned fuel flows into the catalyst, the catalyst temperature will be excessively high. To
prevent this, follow the instructions.
lUse unleaded gasoline only. Leaded gasoline will seriously damage the three way catalyst.
lWhen checking for ignition spark or measuring engine compression, make tests quickly and only when
necessary.
lDo 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 FuelEAS000FS
Use unleaded gasoline with an octane rating of at least 95 (RON).
CAUTION:
Do not use leaded gasoline. Using leaded gasoline will damage the three way catalyst. Using a fuel
other than that specified could adversely affect the emission control devices and systems, and could
also affect the warranty coverage validity.
