WARNING:
For vehicles equipped with a Supplemental Restraint (Air Bag) System:
• Service on and around the air bag system components or wiring must be performed only by an
authorized SUZUKI dealer. Refer to "Air Bag System Components and Wiring Location View" under
"General Description" in Section 10B 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 Section 10B before performing service on or around the air
bag system components or wiring. Failure to follow WARNINGS could result in unintentional activa-
tion 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
"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).
