(k) Care must be taken when jacking up and supporting the
vehicle. Be sure to lift and support the vehicle at the prop­
er locations (See page IN-8).
•
Cancel the parking brake on the level place and
shift the transmission in Neutral (or N position).
•
When jacking up the front wheels of the vehicle at
first place stoppers behind the rear wheels.
•
When jacking up the rear wheels of the vehicle at
first place stoppers before the front wheels.
•
When either the front or rear wheels only should be
jacked up, set rigid racks and place stoppers in front
and behind the other wheels on the ground.
•
After the vehicle is jacked up, be sure to support it
on rigid racks . It is extremely dangerous to do any
work on a vehicle raised on a jack alone, even for
a small job that can be finished quickly.
(I)
Observe the following precautions to avoid damage to the
following parts:
(1)
Do not open the cover or case of the
ECU
unless
absolutely necessary. (If the IC terminals are
touched, the IC may be destroyed by static electric­
ity.)
(2)
To disconnect vacuum hoses, pull off the end, not
the middle of the hose.
(3) To pull apart electrical connectors, pull on the
con-
nectar itself, not the wires.
(4)
Be careful not to drop electrical components, such
as sensors or relays. If they are dropped on a hard
floor, they should be replaced and not reused.
(5)
When steam cleaning an engine, protect the alec-
tronic components, air filter and emission-related
components from water.
(6)
Never use an impact wrench to remove or install
temperature switches or temperature sensors.
(7)
When checking continuity at the wire connector, in-
sert the tester probe carefully to prevent terminals
from bending.
(8)
When using a vacuum gauge, never force the hose
onto a connector that is too large. Use a step-down
adapter for adjustment. Once the hose has been
stretched, it may leak air.
