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).

Engine Oil and Filter Change
WARNING:
New and used engine oil can be hazardous.
Be sure to read ªWARNINGº in General Precaution in Sec-
tion 0A and observe what in written there.
Before draining engine oil, check engine for oil leakage. If any evi-
dence of leakage is found, make sure to correct defective part be-
fore proceeding to the following work.
1) Drain engine oil by removing drain plug.
2) After draining oil, wipe drain plug clean. Reinstall drain plug, and

NOTE:
Before fitting new oil filter, be sure to oil its O-ring. Use engine
oil for this purpose.
4) Screw new filter on oil filter stand by hand until the filter O-ring
contacts the mounting surface.
CAUTION:
To tighten oil filter properly, it is important to accurately
identify the position at which at filter O-ring first contacts
