PRECAUTION

Take care to observe the following precautions when performing inspections or removal and replacement
of body electrical related parts.

1.

SUPPLEMENTAL RESTRAINT SYSTEM (SRS)

The Lexus LS400 is equipped with an SRS (Supplemental Restraint System) such as the driver airbag and
front passenger airbag. failure to carry out service operation in the correct sequence could cause the SRS
to unexpectedly deployed during servicing, possibly leading to a serious accident. Before servicing (includ-
ing removal or installation of parts, inspection or replacement), be sure to read the precautionary codices
in the RS section.

2.

COMBINATION METER SYSTEM

The cold cathode tube connectors (Connectors ”N”, ”P” and ”Q”) in the combination meter are charged with
high voltage AC current when power is supplied, so do not touch them when they are charged.

3.

MICRO COMPUTER PRESET DRIVING POSITION SYSTEM
Power Seat Control System
Power Mirror Control System
Power Tilt and Telescopic Steering System

If the battery negative (–) terminal is disconnected, the preset driving positions stored in memory are erased,
so be sure to note the positions and reset them after the battery terminal is reconnected.

4.

AUDIO SYSTEM

If the battery negative (–) terminal is disconnected, the preset AM, FM 1 and FM 2 stations stored in
memory are erased, so be sure to not the stations and reset them after the battery terminal is recon-
nected.

If the battery negative (–) terminal is disconnected, the ”ANTI–THEFT SYSTEM” will operate when the
terminal is reconnected, but the radio, tape player and CD player will not operate. Be sure to input the
correct ID number so that the radio, tape player and CD player can be operated again.
