WARNING:
For vehicles equipped with Supplement Restraint (Air Bag) System:
D 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" un-
der "General Description" in air bag system section in order to confirm whether you are perform-
ing 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 perform-
ing 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. Ei-
ther 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 sys-
tem may be activated by reserve energy in the Sensing and Diagnostic Module (SDM).
NOTE:
All brake fasteners are important attaching parts in that they could affect the performance of vital parts
and systems, and/or could result in major repair expense. They must be replaced with one of same part
number or with an equivalent part if replacement becomes necessary. Do not use a replacement part of
lesser quality or substitute design. Torque values must be used as specified during reassembly to assure
proper retention of all parts. There is to be no welding as it may result in extensive damage and weakening
of the metal.
