Lexus IS250 IS220d GSE20 ALE20 - SUPPLEMENTAL RESTRAINT SYSTEM

STEERING PAD - DISPOSAL

  • HINT:
  • When scrapping a vehicle equipped with the SRS or disposing of the steering pad, 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 the DISTRIBUTOR.
  • CAUTION:
Never dispose of a steering pad 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 steering pad.
The steering pad 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 steering pad with a deployed airbag.
Do not apply water, etc. to a steering pad with a deployed airbag.
Always wash your hands with water after completing the operation.
1. DISPOSE OF STEERING PAD (WHEN INSTALLED IN VEHICLE)

Using a service-purpose wire harness for the vehicle, tie down the steering pad to the disc wheel.

  • 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 steering pad, 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

Face the airbag deployment side of the steering pad upward on top of a tire and wheel set. Separately tie the left and right sides of the steering pad to the disc wheel through the hub nut holes. Position the SST connector so that it hangs downward through the hub hole of the disc wheel.

  • CAUTION:
Make sure that the wire harness is tight. If there is slack in the wire harness, the steering pad may become loose due to the shock when the airbag is deployed.
Always tie down the steering pad with the airbag deployment side facing upward.
  • NOTICE:
  • The disc wheel will be damaged by the airbag deployment, so use an extra disc wheel.
