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 authorized SUZUKI dealer. Refer to “Air Bag System Components and Wiring Loca-
tion View” under “General 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 Precautions” under “On-Vehicle Service” in
air bag system section before performing service on or around the air bag system compo-
nents 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 “LOCK” position and the negative cable is disconnected from the battery.
