Tesla Model S Owners & Service Manuals

Tesla Model S: Steering Angle Sensor (SAS) Precautions

Caution: Always follow the procedure for fitting and checking the SAS as instructed in the air bag and SRS repairs section. Comply with all safety and installation procedures to ensure the system functions correctly. Caution: Observe the following precautions:

  • Do not unlock and rotate the SAS when it is removed from the vehicle.
  • Always ensure the SAS is removed and installed in its centered position and with the front road wheels in the straight ahead position. Refer to the air bag and SRS repair section for the correct removal and installation procedure.
  • If a new SAS is being installed, ensure the locking tab holding the SAS rotational position is not broken; units with a broken locking tab should not be used.
Warning Labels Warning: Read and follow all warnings and cautions printed on SRS component warning labels. SRS Component Deployment If a vehicle is to be scrapped and contains an undeployed air bag module or pre-tensioner, the module must be manually deployed.

Always observe the following precautions:

Warning: Only personnel who have undergone the appropriate training should undertake deployment of air bag and seat belt pre-tensioner modules.

Warning: A recently deployed air bag or seat belt pre-tensioner is very hot. DO NOT handle a deployed module until at least 30 minutes after deployment.

Warning: Only use approved deployment equipment, and only deploy air bags and pre-tensioner components in a well-ventilated designated area. Ensure components are not damaged or ruptured before deployment.

Warning: Do not lean over air bag modules or seat belt pre-tensioner units when connecting deployment equipment.

 Warning: Contact with chemicals from deployed and damaged SRS components could present a health hazard. Wear protective clothing when handling and seal deployed units in a plastic bag. DO NOT eat, drink or smoke when handling SRS components.

Warning: Deployment of air bag modules and seat belt pre-tensioners can cause injury to personnel in the close vicinity of the deploying unit. Ensure that all personnel are at least 15 m (50 ft) away from the deployment zone. Possible sources of injury include:

  • Impact - due to inflating air bag or pre-tensioner operation causing component 'kick'.
  • Hearing - due to noise produced by deploying air bags and seat belt pre-tensioner units.
  • Burns - hot component parts and gases.
  • Irritation to eyes and lungs - from deploying gases or combustion residue.
Warning: Ensure the SRS component to be deployed is securely fastened to its mounting.


  • Only use deployment equipment approved for the intended purpose.
  • Test the deployment tool before beginning the deployment procedure.
  • Notify the relevant authorities of intention to deploy SRS components.

SRS Component Replacement Policy
