Driver Side Knee Airbag Assembly

SUPPLEMENTAL RESTRAINT SYSTEM: DRIVER SIDE KNEE AIRBAG ASSEMBLY: DISPOSAL

CAUTION:
Before performing pre-disposal deployment of any SRS component, review and closely follow all applicable environmental and hazardous material regulations. Pre-disposal deployment may be considered hazardous material treatment.

1. PRECAUTION

HINT
When scrapping a vehicle equipped with the SRS or disposing of the driver side knee airbag assembly, be sure to deploy the airbag first in accordance with the procedure described below. If any abnormality occurs with the airbag deployment, contact the SERVICE DEPT. of TOYOTA MOTOR SALES, U.S.A., INC.

CAUTION:
* An airbag or pretensioner may be activated by static electricity. To prevent this, be sure to touch a metal surface with bare hands to discharge static electricity before performing this procedure.
* Never dispose of a driver side knee airbag assembly that has an undeployed airbag.
* The airbag produces an exploding sound when it is deployed, so perform the operation outdoors and where it will not create a nuisance to nearby residents.
* When deploying the airbag, always use the specified SST (SRS Airbag Deployment Tool). Perform the operation in a place away from electrical noise.
* When deploying the airbag, perform the operation at least 10 m (33 ft.) away from the driver side knee airbag assembly.
* The driver side knee airbag assembly becomes extremely hot when the airbag is deployed, so do not touch it for at least 30 minutes after deployment.
* Use gloves and safety glasses when handling a driver side knee airbag assembly with a deployed airbag.
* Do not apply water etc. to a driver side knee airbag assembly with a deployed airbag.
* Always wash your hands with water after completing the operation.
2. DISPOSE OF DRIVER SIDE KNEE AIRBAG ASSEMBLY (WHEN INSTALLED IN VEHICLE)

HINT
Prepare a battery as the power source to deploy the airbag.

(a) Check the function of the SST Steering Pad.





(b) Precaution Service Precautions.

(c) Disconnect the cable from the negative battery terminal.

Wait for 90 seconds after disconnecting the cable to prevent the airbag working.

(d) Remove the driver side knee airbag assembly Removal.

(e) Install the SST.

(1) Connect the SST connector to the driver side knee airbag assembly.





SST : 09082-00700

SST : 09082-00770

NOTICE:
To avoid damaging the SST connector and wire harness, do not lock the secondary lock of the twin lock.

(2) Install the driver side knee airbag assembly Installation.

NOTICE:
Take care not to damage the SST wire harness.

(3) Move the SST at least 10 m (33 ft.) away from the vehicle front side window.





(4) Maintaining enough clearance for the SST wire harness in the front side window, close all doors and windows of the vehicle.

NOTICE:
Take care not to damage the SST wire harness.

(5) Connect the red clip of the SST to the battery positive (+) terminal and the black clip of the SST to the battery negative (-) terminal.

(f) Deploy the airbag.

(1) Check that no one is inside the vehicle or within a 10 m (33 ft.) radius of the vehicle.

(2) Press the SST activation switch and deploy the airbag.

CAUTION:
* When deploying the airbag, make sure that no one is near the vehicle.
* The driver side knee airbag assembly becomes extremely hot when the airbag is deployed, so do not touch it for at least 30 minutes after deployment.
* Use gloves and safety glasses when handling a driver side knee airbag assembly with a deployed airbag.
* Do not apply water etc. to a driver side knee airbag assembly with a deployed airbag.
* Always wash your hands with water after completing the operation.
HINT
The airbag is deployed as the LED of the SST activation switch comes on.

3. DISPOSE OF DRIVER SIDE KNEE AIRBAG ASSEMBLY (WHEN NOT INSTALLED IN VEHICLE)

NOTICE:
* When disposing of the driver side knee airbag assembly, never use the customer's vehicle to deploy the airbag.
* Be sure to follow the procedure detailed below when deploying the airbag.

HINT
Prepare a battery as the power source to deploy the airbag.

(a) Check the function of the SST Steering Pad.





(b) Remove the driver side knee airbag assembly Removal.

CAUTION:
* When removing the driver side knee airbag assembly, work must be started 90 seconds after the engine switch is turned off and the negative (-) terminal cable is disconnected from the battery.
* When storing the driver side knee airbag assembly, keep the airbag deployment side facing upward.
(c) Using a service-purpose wire harness for the vehicle, tie down the driver side knee airbag assembly to the tire.





Wire harness:

Stripped wire harness section

1.25 mm2 or more (0.0019 in.2 or more)

CAUTION:
If the wire harness is too thin or an alternative object is used to tie down the driver side knee airbag assembly, it may be snapped by the shock when the airbag is deployed. Always use a wire harness for vehicle use with an area of at least 1.25 mm2 (0.0019 in.2).

HINT
To calculate the area of the stripped wire harness section:

Area = 3.14 x (Diameter)2 divided by 4

(1) Position the driver side knee airbag assembly inside the tire with the airbag deployment side facing inside.

Tire size:

Must exceed the following dimensions

Width:

185 mm (7.28 in.)

Inner diameter:

360 mm (14.17 in.)





CAUTION:
* Make sure that the wire harness is tight. If there is slack in wire harness, the driver side knee airbag assembly may become loose due to the shock when the airbag is deployed.
* Always tie down the driver side knee airbag assembly with the airbag deployment side facing inside the tire.
NOTICE:
The tire will be marked by the airbag deployment, so use an extra tire.

(d) Install the SST.

(1) Connect the SST connector to the driver side knee airbag assembly.





SST : 09082-00770

(e) Place the tires.

(1) Place at least 2 tires under the tire which the driver side knee airbag assembly is tied to.





(2) Place at least 2 tires over the tire which the driver side knee airbag assembly is tied to. The top tire should have the disc wheel installed.

NOTICE:
Do not place the SST connector under the tire because it could be damaged.

(3) Tie the tires together with 2 wire harnesses.





CAUTION:
Make sure that the wire harness is tight. Looseness in the wire harness results in the tires coming free due to the shock when the airbag is deployed.

(f) Install the SST.

(1) Connect the SST connector.





SST : 09082-00700

NOTICE:
To avoid damaging the SST connector and wire harness, do not lock the secondary lock of the twin lock. Also, secure some slack for the SST wire harness inside the tire.

(g) Deploy the airbag.

(1) Connect the red clip of the SST to the battery positive (+) terminal and the black clip of the SST to the battery negative (-) terminal.

(2) Check that no one is within a 10 m (33 ft.) radius of the tire which the driver side knee airbag assembly is tied to.

(3) Press the SST activation switch and deploy the airbag.

CAUTION:
When deploying the airbag, make sure that no one is near the tire.

HINT
The airbag is deployed as the LED of the SST activation switch comes on.

(h) Dispose of the driver side knee airbag assembly.





CAUTION:
* The driver side knee airbag assembly becomes extremely hot when the airbag is deployed, so do not touch it for at least 30 minutes after deployment.
* Use gloves and safety glasses when handling a driver side knee airbag assembly with a deployed airbag.
* Do not apply water etc. to a driver side knee airbag assembly with a deployed airbag.
* Always wash your hands with water after completing the operation.
(1) Remove the driver side knee airbag assembly from the tire.

(2) Place the driver side knee airbag assembly in a plastic bag, tie it tightly and dispose of it as other general part disposal.
