FOR ALL OF VEHICLES
PRECAUTION
1. FOR VEHICLES EQUIPPED WITH SRS AIRBAG AND
SEAT BELT PRETENSIONER
(a) The LAND CRUISER is equipped with an SRS (Supple-
mental Restraint System), such as the driver airbag and
front passenger airbag assembly.
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−240).
(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.

DRIVE BELT
ON−VEHICLE INSPECTION
1. INSPECT DRIVE BELT’S INSTALLATION CONDITION
Check that drive belt fits properly in the ribbed groves.
2. INSPECT DRIVE BELT TENSION
Using a belt tension gauge, check the drive belt tension.
Belt tension gauge:
DENSO BTG −20 (95506−00020) or
Borroughs No. BT −33−73F
Drive belt tension:
New belt 100−150 lbf
Used belt 60−100 lbf
HINT:
”New belt” refers to a belt which has been used less than
5 minutes on a running engine.
”Used belt” refers to a belt which has been on a running
engine for 5 minutes or more.
After installing the drive belt, check that it fits properly in
the ribbed grooves.
