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.
D 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).
NOTE:
D Whether the immobilizer indicator lamp is used in the particular vehicle or not depends on specifica-
tions. If there is a monitor coupler in the engine room near the left strut assembly, the vehicle is not
equipped with immobilizer indicator lamp and if there isn’t, it is equipped with immobilizer indicator
lamp.
D For the descriptions (items) not found in this section, refer to the section 8G of the Service Manual men-
tioned in FOREWORD of this manual.
