PRECAUTIONS

General PrecautionsEAS000FQ

Do not operate the engine for an extended period of time without
proper exhaust ventilation.
Keep the work area well ventilated and free of any inflammable
materials. Special care should be taken when handling any
inflammable or poisonous materials, such as gasoline, refriger-
ant gas, etc. When working in a pit or other enclosed area, be
sure to properly ventilate the area before working with hazard-
ous materials.
Do not smoke while working on the vehicle.

Before jacking up the vehicle, apply wheel chocks or other tire
blocks to the wheels to prevent the vehicle from moving. After
jacking up the vehicle, support the vehicle weight with safety
stands at the points designated for proper lifting before working
on the vehicle.
These operations should be done on a level surface.

When removing a heavy component such as the engine or tran-
saxle/transmission, be careful not to lose your balance and drop
them. Also, do not allow them to strike adjacent parts, especially
the brake tubes and master cylinder.

Before starting repairs which do not require battery power:
Turn off ignition switch.
Disconnect the negative battery terminal.

If the battery terminals are disconnected, recorded memory of
radio and each control unit is erased.

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.

LIFTING POINT

LIFTING POINTPFP:00000
Special Service Tools EAS000FH
CAUTION:

Every time the vehicle is lifted up, maintain the complete vehicle curb condition.

Since the vehicle's center of gravity changes when removing main parts on the front side (engine,
transmission, suspension etc.), support a jack up point on the rear side garage jack with a mission
jack or equivalent.

Since the vehicle's center of gravity changes when removing main parts on the rear side (rear axle,
suspension, etc.), support a jack up point on the front side garage jack with a mission jack or
equivalent.

Be careful not to smash or do not do anything that would affect piping parts.
Garage Jack and Safety Stand EAS000FI
WARNING:

Park the vehicle on a level surface when using the jack. Make sure to avoid damaging pipes,
tubes, etc. under the vehicle.

Never get under the vehicle while it is supported only by the jack. Always use safety stands when
you have to get under the vehicle.

2-Pole Lift EAS000FJ
WARNING:
When lifting the vehicle, open the lift arms as wide as possible and ensure that the front and rear of
the vehicle are well balanced.
When setting the lift arm, do not allow the arm to contact the brake tubes, brake cable, fuel lines and
sill spoiler.

CAUTION:
Make sure vehicle is empty when lifting.

The board-on lift attachment (LM4086-0200) set at front end
of vehicle should be set on the front of the sill under the
front door opening.

Position attachments at front and rear ends of board-on lift.
