8-2 BODY ELECTRICAL SYSTEM
GENERAL DESCRIPTION
The body electrical components of this vehicle are designed to operate on 12 Volts power supplied by the battery.
The electrical system utilizes negative ground polarity.
CAUTIONS IN SERVICING
When performing works related to electric systems, observe follow-
ing cautions for the purpose of protection of electrical parts and pre-
vention of a fire from occurrence.
When removing the battery from the vehicle or disconnecting the
cable from the battery terminals for inspection or service works
on the electric systems, always confirm first that the ignition
switch and all the other switches have been turned OFF. Other-
wise, the semi-conductor part may be damaged.
When disconnecting cables from the battery, be sure to discon-
nect the one from the negative (±) terminal first and then the other
from the positive (+) terminal.
Reverse the above order when connecting the cables to the bat-
tery terminals.
When disconnecting connectors, never pull the wiring harnesses.
Unlock the connector lock first and then pull them apart by holding
connectors themselves.
When connecting connectors, also hold connectors and put them
together until they lock securely (a click is heard).

WARNING:
For vehicles equipped with Supplemental Restraint (Air Bag) System:
Service on and around the air bag system components or wiring must be performed only by an autho-
rized SUZUKI dealer. Refer to ªAir Bag System Components and Wiring Location Viewº under ªGener-
al Descriptionº in air bag system section in order to confirm whether you are performing service on
or near the air bag system components or wiring. Please observe all WARNINGS and ªService Precau-
tionsº under ªOn-Vehicle Serviceº in air bag system section before performing service on or around
the air bag system components or wiring. Failure to follow WARNINGS could result in unintentional
activation of the system or could render the system inoperative. Either of these two conditions may
result in severe injury.
Technical service work must be started at least 90 seconds after the ignition switch is turned to the
ªLOCKº position and the negative cable is disconnected from the battery. Otherwise, the system may
be activated by reserve energy in the Sensing and Diagnostic Module (SDM).
