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 PERFORMING 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 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 specifications.  Following these
instructions can help you avoid damage to parts and
systems.

WHEEL AND TIRE SYSTEM

General Description

480RS008

Replacement wheels or tires must be equivalent to the
originals in load capacity, specified dimension and
mounting configuration.  Improper size or type may affect
bearing life, brake performance, speedometer/odometer
calibration, vehicle ground clearance and tire clearance
to the body and chassis.  All model are equipped with
metric sized tubeless steel belted radial tires.  Correct tire
pressures and driving habits have an important influence
on tire life.  Heavy cornering, excessively rapid
acceleration and unnecessary sharp braking increase
premature and uneven wear.
