PRECAUTION
FOR VEHICLES EQUIPPED WITH SRS
AIRBAG
The 1995 SUPRA is equipped with an SRS (Supplemental
Restraint System), such as the driver airbag, front passenger
airbag and seat belt pretensioners.
Failure to carry out service operations in the correct se-
quence could cause the supplemental restraint system to un-
expectedly deploy during servicing, possibly leading to a seri-
ous accident.
Further, if a mistake is made in servicing the supplemental re-
straint 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 fol-
lowing items carefully, then follow the correct procedure de-
scribed in this manual.
1. Malfunction symptoms of the supplemental restraint system
are difficult to confirm, so the diagnostic 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 RS±41).
2. Work must be started after 90 seconds from the time the
ignition switch is turned to the LOCK position and the
negative (±) terminal cable is disconnected 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 negative (±) terminal cable
from the battery, the SRS may deploy.) IN±10
± INTRODUCTIONPRECAUTION

5. When using electric welding, first disconnect the airbag
connector (yellow color and 2 pins) installed on the glove
compartment finish plate at the left side of the glove
compartment before starting work.
6. When disposing of a vehicle or the airbag assembly
alone, the airbag should be deployed using an SST
before disposal (See page RS±25).
Perform the operation in a safe place away from electri-
cal noise.
Center Airbag Sensor Assembly
1. Never reuse the center airbag sensor assembly involved in
a collision when the SRS has deployed.
2. The connectors to the center airbag sensor assembly should
be connected or disconnected with the sensor mounted on
the floor. If the connectors are connected or disconnected
while the center airbag sensor assembly is not mounted to
the floor, it could cause undesired ignition of the
supplemental restraint system.
3. Work must be started after 90 seconds from the time the
ignition switch is turned to the LOCK position and the
negative (±) terminal cable is disconnected from the battery,
even if only loosening the set bolts of the center airbag
sensor assembly. IN±14
± INTRODUCTIONPRECAUTION

Wire Harness and Connector
The SRS wire harness is integrated with the cowl wire har-
ness assembly and floor wire harness assembly. The wires
for the SRS wire harness are encased in a yellow corrugated
tube. All the connectors for the system are also a standard
yellow color. If the SRS wire harness becomes disconnected
or the connector becomes broken due to an accident, etc.,
repair or replace it as shown on page RS±36.
FOR VEHICLES EQUIPPED WITH A CATALYTIC CONVERTER
CAUTION: If large amounts of unburned gasoline flow into the converter, it may overheat and create a fire
hazard. To prevent this, observe the following precautions and explain them to your customer.
1. Use only unleaded gasoline.
2. Avoid prolonged idling.
Avoid running the engine at idle speed for more than 20 minutes.
3. Avoid spark jump test.
(a) Perform spark jump test only when absolutely necessary. Perform this test as rapidly as possible.
(b) While testing, never race the engine.
4. Avoid prolonged engine compression measurement.
Engine compression tests must be done as rapidly as possible.
5. Do not run engine when fuel tank is nearly empty.
This may cause the engine to misfire and create an extra load on the converter.
6. Avoid coasting with ignition turned off and prolonged braking.
7. Do not dispose of used catalyst along with parts contaminated with gasoline or oil.
