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 autho-
rized SUZUKI dealer. Refer to ªAir Bag System Components and Wiring Location Viewº under ªGener-
al Descriptionº 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 ªService Precau-
tionsº under ªOn-Vehicle Serviceº 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.
Technical service work must be started at least 90 seconds after the ignition switch is turned to the
ªLOCKº 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).

INSPECTION
MIRROR SWITCH
1) Remove mirror switch from instrument panel.
2) Check for continuity between terminals at each switch position
as shown below.
If check result is not as specified, replace mirror switch.
DOOR MIRROR ACTUATOR
1) Remove garnish from door.
2) Disconnect door mirror coupler.
3) Check that door mirror operates properly when battery voltage
is applied to connector terminals.
Connect battery positive and negative terminal to the door mirror
terminal shown below and check operation.
If it does not operate as specified in table below, replace door
mirror assembly.
