(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 ).
Release the parking brake on a level surface and
shift to in Neutral or N range.
When jacking up the front wheels of the vehicle, at
first place chocks behind the rear wheels.
When jacking up the rear wheels of the vehicle,
place chocks in front of the front wheels.
When jacking up only the front or rear wheels, set
rigid racks and place chocks on front and behind the
wheels in contact with 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.
(l) 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. (Static electricity transmitted
through human touch may destroy the IC.)
(2) To disconnect vacuum hoses, pull off the end of the
hose, not the middle.
(3) To pull apart electrical connectors, pull on the con-
nector 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 elec-
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.

(m) Installation and removal of vacuum hose:
(1) When disconnecting vacuum hoses, use tags to
identify where they should be reconnected to.
(2) After completing a job, double check that the vacu-
um hoses are properly connected. A label under the
hood shows the proper layout.
(n) Unless otherwise stated, all resistance should be mea-
sured at an ambient temperature of 20°C (68°F). Mea-
surement should be made after the engine has cooled

PRECAUTION
1. FOR VEHICLES EQUIPPED WITH SRS AIRBAG AND
SEAT BELT PRETENSIONER
(a) The LEXUS IS300 is equipped with an Supplemental Re-
straint System (SRS), such as the driver airbag, front pas-
senger airbag assembly, side airbag assembly, curtain
shield airbag assembly and seat belt pretensioners.
Failure to carry out service operations in the correct se-
quence could cause the supplemental restraint system to
unexpectedly deploy during servicing, possibly leading to
a serious accident.
Further, if a mistake is made in servicing the supplemental
restraint system, it is possible the SRS may fail to operate
when required. Before servicing (including removal or
installation of parts, inspection or replacement), be sure
to read the following items carefully, then follow the cor-
rect procedure described in this manual.
(b) GENERAL NOTICE
(1) Malfunction symptoms of the SRS are difficult to
confirm, so the diagnostic trouble codes become
the most important source of information when trou-
bleshooting. When troubleshooting the supplemen-
tal restraint system, always check the diagnostic
trouble codes before disconnecting the battery (see
page DI-607 ).
(2) Work must be started after 90 seconds from the
time the ignition switch is turned to the LOCK posi-
tion and the negative (-) terminal cable is discon-
nected from the battery.
(The supplemental restraint system is equipped
with a back-up power source so that if work is
started within 90 seconds of disconnecting the neg-
ative (-) terminal cable from the battery, the SRS
may deploy.)
When the negative (-) terminal cable is discon-
nected from the battery, memory of the clock and
audio systems will be cancelled. So before starting
work, make a record of the contents memorized by
the each memory system. Then when work is fin-
ished, reset the clock and audio systems as before.
To avoid erasing the memory of each memory sys-
tem, never use a back-up power supply from anoth-
er battery.

front passenger airbag assembly, side airbag as-
sembly, curtain shield airbag assembly, front airbag
sensor assembly or seat belt pretensioner if it has
been dropped, or if there are cracks, dents or other
defects in its case, bracket or connector.
(8) Do not directly expose the steering wheel pad, front
passenger airbag assembly, side airbag assembly,
curtain shield airbag assembly, front airbag sensor,
side and curtain shied airbag sensor assembly or
seat belt pretensioner to hot air or flames.
(9) Use a voltmeter/ohmmeter with high impedance (10
kΩ/V minimum) for troubleshooting of the electrical
circuit.
(10) Information labels are attached to the periphery of
the SRS components. Follow the instructions on the
labels.
(11) After work on the SRS is completed, check the SRS
warning light (see page DI-607 ).
(c) SPIRAL CABLE (in Combination Switch)
The steering wheel must be fitted correctly to the steering
column with the spiral cable at the neutral position, other-
wise cable disconnection and other troubles may result.

(a) Never apply driving force when RH or LH rear wheel only
is touching the ground.
(b) During service/rectification work never spin (race) the RH
or LH rear wheel only such as with ON-The-Car type
wheel balancer, both rear wheels must be off the ground.
HINT:
In case of the above, due to the construction of the LSD
the driving force is transmitted to the opposite wheel and
therefore it is possible for the vehicle to start suddenly if
only one rear wheel is off the ground. Furthermore it could
result in component damage to the LSD due to the loads
acting on it.
Always raise both rear wheels off the ground and support
the vehicle on suitable safety stand.
