BODY ELECTRICAL SYSTEM
PRECAUTION
Take care to observe the following precautions when performing inspections o\
r removal and replacement
of body electrical related parts.
1. HEADLIGHT SYSTEM
Halogen bulbs have pressurized gas inside and require special handling. They ca\
n 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 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 th\
e correct sequence could cause the
SRS to unexpectedly deploy during servicing, possibly leading to a serious accident. Before servicing (in\
-
cluding removal or installation of parts, inspection or replacement), be sure t\
o 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 af\
ter 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 in the IN section.
