Body Electrical System - Precautions: Precaution

Take care to observe the following precautions when performing inspections or removal and replacement of body electrical related parts.

1. HEADLIGHT SYSTEM (Halogen bulb) 

   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. HEADLIGHT SYSTEM (HID bulb) 
   • HID 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.

   • When high voltage socket of discharge headlight is touched with the light control switch HEAD, high voltage of 20,000 V is momentarily generated. This might lead to a serious accident.
   • Never connect the tester to the high voltage socket of discharge headlight for measurement, as this can lead to a serious accident because of high voltage.
   • When performing operation related to the discharge of headlights, make sure to do it in a place with no water or moisture to prevent electric shock, with the light control switch OFF, battery terminal(s) removed, connector of light control ECU disconnected.
   • When performing operation related to the discharge of headlights, make sure to do it after assembling has been completely over and never light up without a bulb installed.
3. SUPPLEMENTAL RESTRAINT SYSTEM (SRS) 

   The LEXUS RX300 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 deployed 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 codes in the RS section.

4. COMBINATION METER SYSTEM 

   The cold cathode tube connectors (Connectors "N", "P" and "Q") in the combination meter are charged with high voltage AC current when power is supplied, so do not touch them when they are charged.

5. Power Seat Control System: 

   MICRO COMPUTER PRESET DRIVING POSITION SYSTEM 

   If the battery negative (-) terminal is disconnected, the preset driving positions stored in memory are erased, so be sure to note the positions and reset them after the battery terminal is reconnected.

6. 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 reconnected. 1

7. MOBILE COMMUNICATION SYSTEM 

   If the vehicle is equipped with a mobile communication system, refer to precautions in the IN section.
