a new one.

When installing the seat position sensor assembly
center, be careful that the SRS wiring does not inter-
fere with other parts and that it is not pinched be-
tween other parts.

Back Door Power Window Control SystemBE±77
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 may burst or shatter if scratched or the bulb is 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 SEQUOIA 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 and installation of parts,
inspection or replacement), be sure to read the precautions in the RS section (See page xx±xxx).
3. AUDIO SYSTEM
If the battery negative (±) terminal is disconnected, the preset AM, FM 1 and FM 2 stations stored in the
memory are erased, so be sure to make a memo of the stations and reset them after the battery terminal
is reconnected.
4. MOBILE COMMUNICATION SYSTEM
If the vehicle is equipped with a mobile communication system, refer to precautions in the IN section.
