2002 ACCESSORIES & EQUIPMENT Body Electrical/Troubleshooting - Corolla BODY ELECTRICAL SYSTEM PRECAUTION 1. 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. 2. SRS (SUPPLEMENTAL RESTRAINT SYSTEM) The COROLLA is equipped with an SRS (Supplemental Restraint System) such as the driver 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 the RS section. 3. AUDIO SYSTEM If the negative (-) terminal cable is disconnected from the battery, the preset AM, FM 1 and FM 2 stations stored in memory are erased, so be sure to note the stations and reset them after the negative (-) terminal cable is reconnected to the battery. 4. MOBILE COMMUNICATION SYSTEM If the vehicle is equipped with a mobile communication system, refer to PRECAUTIONS .
