body electrical related parts S S S S S S S 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 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 leads to a serious accident because of high voltage When performing operation related to the discharge headlight, make sure to it in the place with no water of rain to prevent electric shock, with light control switch OFF, battery terminal removed, connector of light control ECU disconnected When performing operation related to the discharge headlight, make sure to it after assembling has been completely over and never light up without a bulb installed Do not light up the discharge headlight using another power source except vehicle’s When there is a defect on the discharge headlight or any shock has been applied to it, replace the light with a new one Even if the light operates normally, there is a possibility that the fail−safe function works SRS (SUPPLEMENTAL RESTRAINT SYSTEM) The LAND CRUISER 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 S S AUDIO SYSTEM If the negative (−) terminal cable is disconnected from the battery, the preset AM, FM and FM 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 If the negative (−) terminal cable is disconnected from the battery, the ”ANTI−THEFT SYSTEM” will operate when the cable 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 MOBILE COMMUNICATION
