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.
