(m)

Installation and removal of vacuum hose:
(1)

When disconnecting vacuum hoses, use tags to
identify how 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 is measured at an
ambient temperature of 20°C (68°F). Because the resis-
tance may be outside specifications if measured at high
temperatures immediately after the vehicle has been run-
ning, measurement should be made when the engine has
cooled down.

FOR ALL OF VEHICLES

PRECAUTION

1.

FOR VEHICLES EQUIPPED WITH SRS AIRBAG AND
SEAT BELT PRETENSIONER

(a)

The LEXUS RX300 is equipped with an SRS (Supple-
mental Restraint System), such as the driver airbag, front
passenger airbag assembly, side airbag assembly and
seat belt pretensioner.
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 supplemental re-
straint system are difficult to confirm, so the diag-
nostic trouble codes become the most important
source of information when troubleshooting. When
troubleshooting  the supplemental restraint system,
always inspect the diagnostic trouble codes before
disconnecting the battery (See page DI–305).

(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.
This vehicle has power seat, which are all equipped
with memory function, it is not possible to make a re-
cord of the memory contents. So when the work is
finished, therefore it will be necessary to explain this
fact to the customer, and ask the customer to adjust
the features and reset the memory.
