PRECAUTIONS
Revision: 2007 April2007 M35/M45

Wear protective clothing, including impervious gloves where practicable.

Do not put oily rags in pockets.

Avoid contaminating clothes, particularly underpants, with oil.

Heavily soiled clothing and oil-impregnated footwear should not be worn. Overalls must be cleaned regu-
larly.

First aid treatment should be obtained immediately for open cuts and wounds.

Use barrier creams, applying them before each work period, to help the removal of oil from the skin.

Wash with soap and water to ensure all oil is removed (skin cleansers and nail brushes will help). Prepa-
rations containing lanolin replace the natural skin oils which have been removed.

Do not use gasoline, kerosene, diesel fuel, gas oil, thinners or solvents for cleaning skin.

If skin disorders develop, obtain medical advice without delay.

Where practical, degrease components prior to handling.

Where there is a risk of eye contact, eye protection should be worn, for example, chemical goggles or face
shields; in addition an eye wash facility should be provided.
Precautions for the EnvironmentNAS000BG
In servicing the vehicle, it may be necessary to use, dispose of or recycle hazardous, flammable, or poisonous
materials, such as gasoline, refrigerant gas, solvents, oil, oil filter, air bag modules, seat belt pretensioners,
etc. Disposal, recycling, and transportation of any hazardous materials should be performed in compliance
with applicable federal, state and local laws and regulations.
Precautions for Air Conditioning NAS0009M
Use an approved refrigerant recovery unit any time the air conditioning system must be discharged. Refer to
ATC/MTC section “HFC-134a (R-134a) Service Procedure”, “REFRIGERANT LINES” for specific instructions.

How to Follow Trouble DiagnosesNAS0007M
DESCRIPTION
NOTICE:
Trouble diagnoses indicate work procedures required to diagnose problems effectively. Observe the following
instructions before diagnosing.
1.Before performing trouble diagnoses, read the “Preliminary Check”, the “Symptom Chart” or the
“Work Flow”.
2.After repairs, re-check that the problem has been completely eliminated.
3.Refer to Component Parts and Harness Connector Location for the Systems described in each
section for identification/location of components and harness connectors.
4.Refer to the Circuit Diagram for quick pinpoint check.
If you need to check circuit continuity between harness connectors in more detail, such as when a
sub-harness is used, refer to Wiring Diagram in each individual section and Harness Layout in PG
section for identification of harness connectors.
5.When checking circuit continuity, ignition switch should be OFF.
6.Before checking voltage at connectors, check battery voltage.
7.After accomplishing the Diagnostic Procedures and Electrical Components Inspection, make sure
that all harness connectors are reconnected as they were.
