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

Whether the immobilizer indicator lamp is used in the particular vehicle or not depends on vehicle specifi-
cations. If there is a exhaust No.1 pipe with manifold catalytic converter, the vehicle is equipped with immo-
bilizer indicator lamp and if there isn't , it is not equipped with immobilizer indicator lamp. For details of
exhaust No.1 pipe, refer to Section 6K in this manual.
