The Vehicle Identification Number is also im­
printed on the:

• Equipment Identification Plate
• Vehicle Safety Certification Label
• And on a frame rail.

VEHICLE CODE PLATE
A metal vehicle code plate (Fig. 2) is attached to

top,
right side of cowl below cowl grille. There can be a maximum of seven rows of vehicle information im­
printed on the plate. The information should be read
from left to right, starting with line 1 at the bottom
of the plate up to line 7 (as applicable) at the top of
the code plate. Refer to the decoding chart to decode lines 1
through 3.
Lines 4 through 7 on the plate are imprinted in se­
quence according to the following descriptions:
• 3-character sales code • 3-digit numerical code
• 6-digit SEC code If there is not enough space left in the row for all
of the 6-digit SEC code:
• The unused space will remain blank
• The code will be listed in the next row.
The last nine positions of row 7 will contain a
2-digit code and a 6-digit serial number.
The last code on a vehicle code plate will be fol­
lowed by the imprinted word END. When two plates
are required, the last available spaces on the first
plate will be imprinted with the letters CTD (for con­ tinued).
When a second vehicle code plate is necessary, the
first four spaces on each row will not be used because of the plate overlap.
To retrieve information from a vehicle code plate:
• Illuminate the plate with a shop light
• View the plate via the cowl grille slots
• Record the needed coded information.

LIFTING RECOMMENDATIONS
Refer to the Owner's Manual for emergency vehicle
lifting procedures.
FLOOR JACK When properly positioned, a floor jack can be used
to lift a vehicle (Fig. 8). Support the vehicle in the
raised position with jack stands at the front and rear ends of the frame rails.

CAUTION:
Do not

• A ramp-type, drive-on hoist
When a frame-contact type hoist is used, verify
that the lifting pads are positioned properly (Fig. 8).

When a twin-post hoist is used, a 4 x 4 x 12-inch
wood spacer also could be required. Place the wood spacer under the front axle (opposite the differential
housing). This will maintain balance and level lift­ ing.

VEHICLE
TOWING
RECOMMENDATIONS
When it is necessary to tow a Ram Truck, the rec­
ommended method is either:
• the sling-type, rear-end raised towing method; or
• the wheel-lift towing method with a tow dolly lo­
cated under the front wheels. A vehicle with flat-bed hauling equipment can also
be used to transport a disabled vehicle.

LUBRICATION
AND
MAINTENANCE

• A vehicle equipped with SAE approved sling-type
towing equipment can be used (Fig. 10). However,
many vehicles are equipped with air dams, spoilers, and/or ground effect panels. In this case a wheel-lift
towing vehicle or a flat-bed hauling vehicle is recom­ mended (Fig. 10). If a flat bed device is used, the ap­
proach angle should not exceed 15 degrees.
GROUND CLEARANCE The lifted wheels of the disabled vehicle should be
a minimum of 10 cm (4 in.) off the ground. Make
sure there is enough clearance at the opposite end.
This is critical when towing over rough terrain. If necessary, the rear ground clearance can be in­creased by removing the wheels from the lifted end
and then towing with the lifted end closer to the
ground. If the rear wheels are removed, secure the
brake drums. A 20 cm (8 in.) ground clearance must
be maintained between brake drums or rotors and the ground.
SAFETY PRECAUTIONS The following safety precautions must be consid­
ered when preparing for and during a vehicle towing operation:
• Remove exhaust pipe tips that interfere with the
tow sling and crossbar • Padding should be placed between the tow sling/
crossbar and any painted surfaces
• If the vehicle is damaged, secure the loose and pro­
truding parts
• Always use a safety chain system that is indepen­ dent of the lifting and towing equipment
• When placing tow hooks on the rear axle, position them so they do not damage the brake tubing or
hoses
• Do not allow any of the towing equipment to con­
tact the fuel tank
• Do not tow the vehicle by connecting to the front
or rear shock absorbers
• The operator should not go under a vehicle while
it is lifted by the towing equipment. The vehicle
should first be supported by safety stands
• Do not allow passengers in a vehicle being towed
• Observe all state and local laws involving warning signals, night illumination, speed, etc.
• Do not exceed a towing speed of 48 km/h (30 mph)
• Avoid towing distances of more than 24 km (15
miles) whenever possible • Do not attach tow chains or a tow sling to a
bumper, the steering linkage, the universal joints, or a drive shaft
REAR-END RAISED TOWING It is recommended that the rear-end raised towing
method be used. Vehicles can be towed with the front
wheels on the ground for extended distances at speeds not exceeding 48 km/h (30 mph) (Fig. 11). (1) Attach the J-hooks around the axle shaft tubes
outboard of the rear springs. (2) Position and center the sling under and for­
ward of the rear bumper. (3) Attach safety chains (with pads) at each end of
the rear bumper.
(4) Turn the ignition switch to the OFF position to
unlock the steering wheel. (5) Clamp the steering wheel with the front wheels
in the straight ahead position.

CAUTION:
Do not use the steering
column
lock
to

secure
front
wheel
in the straight-ahead
position.

(6) Shift the transmission to NEUTRAL.

FRONT'END RAISED TOWING If a vehicle cannot be towed from the rear, the
front-end raised towing method normally can be
used (Fig. 12). (1) Center the sling with the bumper and position
it at the frame front crossmember.

CAUTION:

chains

(2) Route the J-hooks and tow chains over the
steering linkage outboard of the coil spring.
(3) Attach the J-hooks to the outer end of the
lower suspension arms.
(4) Raise the vehicle.
(5.) Attach the safety chains to the disabled vehicle
at the frame rails.

LUBRICATION
AND
MAINTENANCE
0 - 21 ROUTINE INSPECTION
It is recommended that the drive belt(s) be rou­
tinely inspected for cracks, fraying and excessive
wear. Replace as necessary.

EXHAUST SYSTEM
An exhaust system must be properly aligned to
prevent stress, leakage, and vehicle body contact.
MAINTENANCE SCHEDULE Inspect the exhaust system at the interval specified
in maintenance schedule.
INSPECTION Inspect for cracked or loose joints, corrosion dam­

age,
and worn or broken hangers. Replace all compo­
nents that are damaged. Do not attempt repair. Also,
inspect for the following conditions and correct as
necessary:
• Exhaust system leaks, misalignment • Contact with body panels or the frame
• Catalytic converter bulging or excessive heat dam­
age

CAUTION:
A
catalytic converter
will
become
con­

taminated
if
leaded gasoline
is
burned
in the en­

gine.
If
this
occurs,
the
complete converter must
be
replaced.

AIR-CONDITIONER COMPRESSOR LUBRICANT
AND
REFRIGERANT
The lubricant level in the compressor should be
checked if there are indications that oil was lost.
Loss of lubricating oil usually accompanies a loss of
refrigerant. The presence of bubbles in sight glass in­ dicates that loss of refrigerant has occurred. For additional information involving the A/C sys­
tem, refer to Group 24—Heater And Air Condition­ ing.
