Service Precaution 

WARNING: 
THIS VEHICLE HAS A SUPPLEMENTAL
RESTRAINT SYSTEM (SRS).  REFER TO THE SRS
COMPONENT AND WIRING LOCATION VIEW IN
ORDER TO DETERMINE WHETHER YOU ARE
PERFORMING SERVICE ON OR NEAR THE SRS
COMPONENTS OR THE SRS WIRING. WHEN YOU
ARE REFORMING SERVICE ON OR NEAR THE
SRS COMPONENTS OR THE SRS WIRING, REFER
TO THE SRS SERVICE INFORMATION. FAILURE
TO FOLLOW WARNINGS COULD RESULT IN
POSSIBLE AIR BAG DEPLOYMENT, PERSONAL
INJURY, OR OTHERWISE UNNEEDED SRS
SYSTEM REPAIRS.  

CAUTION: 
Always use the correct fastener in the proper
location. When you replace a fastener, use ONLY
the exact part number for that application.
ISUZU/GM will call out those fasteners that require
a replacement after removal. ISUZU/GM will also 
call out the fasteners that require thread lockers or
thread sealant. UNLESS OTHERWISE SPECIFIED,
do not use supplemental coatings (Paints,
greases, or other corrosion inhibitors) on threaded
fasteners or fastener joint interfaces. Generally,
such coatings adversely affect the fastener torque
and the joint clamping force, and may damage the
fastener.  When you install fasteners, use the
correct tightening sequence and specification.
Following these instructions can help you avoid
damage to parts and systems.
