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 “System Components and Wiring Location View” under “Gen-
eral 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 Precautions”
under “On-Vehicle Service” in Section 10B before performing service on or around the air bag sys-
tem components or wiring. Failure to follow WARNINGS could result in unintentional activation of
