WARNING:
For vehicles equipped with Supplemental Restraint (Air Bag) System:
D Service on and around the air bag system components or wiring must be performed only by an autho-
rized SUZUKI dealer. Refer to "Air Bag System Components and Wiring Location View" under "Gener-
al Description" 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 "Service Precau-
tions" under "On-Vehicle Service" 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.

"LOCK" 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).
