DESCRIPTION AND OPERATION
VEHICLE IDENTIFICATION NUMBER
The Vehicle Identification Number (VIN) is located
on the upper left corner of the instrument panel,
near the left A-Pillar. The VIN consists of 17 charac-
ters in a combination of letters and numbers that
provide specific information about the vehicle (Fig.
1). Refer to VIN Code Decoding Chart.
To protect the consumer from theft and possible
fraud the manufacturer is required to include a
Check Digit at the ninth position of the Vehicle Iden-
tification Number. The check digit is used by the
manufacturer and government agencies to verify the
authenticity of the vehicle and official documenta-
tion. The formula to use the check digit is not
released to the general public.

FASTENER USAGE
WARNING: USE OF AN INCORRECT FASTENER
MAY RESULT IN COMPONENT DAMAGE OR PER-
SONAL INJURY.
Figure art, specifications and tightening torque ref-
erences in this manual are identified in metric and
SAE format.
During any maintenance or repair procedures, it is
important to salvage all fasteners (nuts, bolts, etc.)
for reassembly. If the fastener is not salvageable, a
fastener of equivalent specification must be use.
METRIC SYSTEM
The metric system is based on quantities of one,
ten, one hundred, one thousand and one million (Fig.
5).
The following chart will assist in converting metric
units to equivalent English and SAE units, or vise
versa.
