Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Section 440 (Turn Signal And Hazard Warning System): Precautions
- Headlight system
:
Halogen bulbs have pressurized gas inside and require special handling. They can burst if scratched or dropped. Hold a bulb only by its plastic or metal case.
Don't touch the glass part of a bulb with bare hands.
- SRS (Supplemental Restraint System)
The PRIUS is equipped with an SRS (Supplemental Restraint System) such as the driver AIRBAG, side AIRBAG and front passenger AIRBAG. Failure to carry out service operation in the correct sequence could cause the SRS to unexpectedly deploy during servicing, possibly leading to a serious accident. Before servicing (including removal or installation of parts, inspection or replacement), be sure to read the precautionary notices in AIR BAG SAFETY PRECAUTIONS .
