CLUTCH
ON±VEHICLE INSPECTION
1. SET MANIFOLD GAUGE SET (See page AC±18)
2. START ENGINE
3. INSPECT COMPRESSOR FOR METALLIC SOUND
Check if a metallic sound can be heard from the compressor
when the A/C switch is on.
If a metallic sound cannot be heard, replace the compressor as-
sembly.
4. INSPECT REFRIGERANT PRESSURE
(See page AC±3)
5. STOP ENGINE
6. INSPECT VISUALLY FOR LEAKAGE OF REFRIGER-
ANT FROM SAFETY SEAL
Using a gas leak detector, check for leakage of refrigerant.
If there is any leakage, replace the compressor assembly.
7. REMOVE MANIFOLD GAUGE SET
(See page AC±19)
8. CHECK FOR LEAKAGE OF GREASE FROM CLUTCH
BEARING
9. CHECK FOR SIGNS OF OIL ON PRESSURE PLATE
If necessary, repair or replace.
10. INSPECT MAGNETIC CLUTCH BEARING FOR NOISE
(a) Start the engine.
(b) Check if abnormal noise is heard from near the compres-
sor when the A/C switch is OFF.
If abnormal noise is being emitted, replace the magnetic clutch.
11. INSPECT MAGNETIC CLUTCH OPERATION
(a) Disconnect the connector.
(b) Connect the positive (+) lead from the battery to terminal
3 and the negative (±) lead to body ground.
(c) Check that the magnetic clutch is energized.
If operation is not as specified, replace the magnetic clutch.
12. INSPECT COMPRESSOR LOCK SENSOR RESIS-
TANCE
(a) Disconnect the connector.
(b) Measure the resistance between terminals 1 and 2.
Standard resistance:
165 to 205 W at 20°C (68°F)
If resistance is not as specified, replace the compressor.

In order to be effective, the SRS airbags must deploy with
tremendous speed. The rapid deployment of the SRS air-
bags makes the SRS airbags themselves potential sources
of serious injury if an occupant is too close to an airbag,
or if an object or some part of his or her body has been
placed between the occupant and the airbag at the time of
deployment. This is just one example of how the instruc-
tions in Section 1±3 of this Owner 's Manual will help en-
sure proper use of the occupant restraint systems, and
increase the safety they can provide to you and your fami-
ly in the event of an accident.
Toyota recommends you to read the provisions in Section
1±3 carefully and refer to them as needed during your time
of ownership of this vehicle.Event data recorder
Your vehicle has computers that monitor and control cer-
tain aspects of your vehicle. These computers assist in
driving and maintaining optimal vehicle performance. Be-
sides storing data useful for troubleshooting, there is a
system to record data in a crash or a near car crash
event. This is called an Event Data Recorder (EDR).
The SRS airbag sensor assembly contains the EDR. In a
crash or a near car crash event, this device records some
or all of the following information:

Engine speed

Whether the brake pedal was applied or not

Vehicle speed

To what extent the accelerator pedal was depressed

Position of the transmission selector lever

Whether the driver and front passenger wore the seat
belts or not

Driver 's seat position

Front passenger 's occupant classification
