VEHICLE IDENTIFICATION
NUMBER
DESCRIPTION
VIN CODING/LOCATIONS
The Vehicle Identification Number (VIN) plate is
located on the lower windshield fence near the left
a-pillar (Fig. 1). The VIN contains 17 characters that
provide data concerning the vehicle. Refer to the VIN
decoding chart to determine the identification of a
vehicle.
The VIN is also imprinted on the:
²Body Code Plate.
²Equipment Identification Plate.
²Vehicle Safety Certification Label.
²Frame rail.
To protect the consumer from theft and possible
fraud the manufacturer is required to include a
Check Digit at the ninth position of the VIN. The
check digit is used by the manufacturer and govern-
ment agencies to verify the authenticity of the vehi-cle and official documentation. The formula to use
the check digit is not released to the general public.

VEHICLE EMISSION CONTROL
INFORMATION (VECI)
DESCRIPTION
All models have a Vehicle Emission Control Infor-
mation (VECI) Label. DaimlerChrysler permanently
attaches the label in the engine compartment (Fig.
2). The label cannot be removed without defacing
label information and destroying label.
The label contains the vehicle's emission specifica-
tions and vacuum hose routings. All hoses must be
connected and routed according to the label.
The label also contains an engine vacuum sche-
matic. There are unique labels for vehicles built for
sale in the state of California and the country of
Canada. Canadian labels are written in both the
English and French languages.
The VECI label contains the following:
²Engine family and displacement
²Evaporative family
²Emission control system schematic
²Certification application
²Engine timing specifications (if adjustable)²Idle speeds (if adjustable)
²Spark plug and gap

BODY CODE PLATE
DESCRIPTION
The Body Code Plate (Fig. 4) is located on the right
front hydroform fender rail just behind the headlight
assembly (Fig. 3). There are seven lines of informa-
tion on the body code plate. Lines 5, 6, and 7 are not
used to define service information. Information reads
from left to right, starting with line 4 in the center of
the plate to line 1 at the bottom of the plate.
The last code imprinted on a vehicle code plate will
be followed by the imprinted word END. When two
vehicle code plates are required, the last available
spaces on the first plate will be imprinted with the
letters CTD (for continued).
When a second vehicle code plate is necessary, the
first four spaces on each row will not be used because
of the plate overlap.

INTERNATIONAL VEHICLE
CONTROL & DISPLAY
SYMBOLS
DESCRIPTION - INTERNATIONAL SYMBOLS
The graphic symbols illustrated in the following
International Control and Display Symbols Chart are
used to identify various instrument controls. The
symbols correspond to the controls and displays that
are located on the instrument panel.
FASTENER IDENTIFICATION
DESCRIPTION
The SAE bolt strength grades range from grade 2
to grade 8. The higher the grade number, the greater
the bolt strength. Identification is determined by the
line marks on the top of each bolt head. The actual
bolt strength grade corresponds to the number of line
marks plus 2. The most commonly used metric bolt
strength classes are 9.8 and 10.9. The metric
strength class identification number is imprinted on
the head of the bolt. The higher the class number,
the greater the bolt strength. Some metric nuts are
imprinted with a single-digit strength class on the
nut face. Refer to the Fastener Identification and
Fastener Strength Charts (Fig. 5) and (Fig. 6).

FASTENER USAGE
DESCRIPTION - FASTENER USAGE
WARNING: USE OF AN INCORRECT FASTENER
MAY RESULT IN COMPONENT DAMAGE OR PER-
SONAL INJURY.
Fasteners and torque specifications references in
this Service 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 used.
THREADED HOLE REPAIR
DESCRIPTION - THREADED HOLE REPAIR
Most stripped threaded holes can be repaired using
a Helicoilt. Follow the vehicle or Helicoiltrecommen-
dations for application and repair procedures.
METRIC SYSTEM
DESCRIPTION
The metric system is based on quantities of one,
ten, one hundred, one thousand and one million.
The following chart will assist in converting metric
units to equivalent English and SAE units, or vise
versa.
