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 INFOMATION

. 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 will call out those fasteners that require  a
replacement after removal. ISUZU 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.
