Tundra 2WD V8-4.6L (1UR-FE) (2010)
(1) Check that no one is inside the vehicle or within a 10 m (32.8 ft.) radius of the vehicle.
(2) Press SST activation switch to deploy the airbag.
CAUTION:
*
When deploying the airbag, make sure that no one is near the vehicle.
*
The lower No. 1 instrument panel airbag 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 lower No. 1 instrument panel airbag with a deployed airbag.
*
Do not apply water to a lower No. 1 instrument panel airbag with a deployed airbag.
*
Always wash your hands with water after completing the operation.
HINT
The airbag is deployed as the LED of SST activation switch comes on.
2. DISPOSE OF LOWER NO. 1 INSTRUMENT PANEL AIRBAG ASSEMBLY (WHEN NOT INSTALLED IN VEHICLE)
NOTICE:
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 SST See: Testing and Inspection/Initial Inspection and Diagnostic Overview/Diagnosis System.
(b) Remove the lower No. 1 instrument panel airbag See: Removal and Replacement/Driver Side Knee Airbag Assembly/Removal.
CAUTION:
*
When removing the lower No. 1 instrument panel airbag, wait at least 90 seconds after the ignition switch is turned off and the
cable is disconnected from the negative (-) battery terminal before starting work.
*
When storing the lower No. 1 instrument panel airbag, keep the airbag deployment side facing upward.
(c) Using a service-purpose wire harness for the vehicle, tie down the lower No. 1 instrument panel airbag to a tire.
Cross-sectional area of stripped wire harness section:
1.25 mm2 or more (0.00192 in.2 or more)
CAUTION:
If the wire harness is too thin or an alternative object is used to tie down the lower No. 1 instrument panel airbag, it may be snapped
by the shock when the airbag is deployed. Always use a wire harness for vehicle use with a cross-sectional area of at least 1.25 mm2
(0.00192 in.2).
HINT
To calculate the cross-sectional area of the stripped wire harness section: Cross-sectional area = 3.14 x (Diameter)2 / 4
(1) Position the lower No. 1 instrument panel airbag inside a tire with the airbag deployment side facing inside.
