BODY ELECTRICAL SYSTEM
PRECAUTION
Take care to observe the following precautions when performing inspections or removal and replacement
of body electrical related parts.
1. LIGHTING SYSTEM
Halogen bulbs have pressurized gas inside and require special handling.
They can burst or scatter 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 TOYOTA T100 is equipped with an SRS (Supplemental Restraint System) such as the driver airbag.
Failure to carry out service operations 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 battery negative (−) terminal is disconnected, 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 battery terminal is recon-
nected.
If the battery negative (−) terminal is disconnected, the ”ANTI−THEFT SYSTEM” will operate when the
terminal is reconnected, but the radio, tape player and CD player will not operate. Be sure to input the
correct ID number so that the radio, tape player and CD player can be operated again.
4. MOBILE COMMUNICATION SYSTEM
If the vehicle is equipped with a mobile communication system, refer to precautions in the IN section.
