The Vehicle Identification Number is also im­
printed on the:
• Body Code Plate
• 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.

LUBRICATION
AND
MAINTENANCE

• Commercial service
When a vehicle is continuously subjected to severe
driving conditions, lubricate:
• Body components
• All the driveline coupling joints
• Steering linkage More often than normal driving conditions

DUSTY
AREAS
With this type of severe driving condition, special
care should be given to the:
• Engine air cleaner filter
• PCV filter
• Crankcase ventilation system
• Brake booster control valve air filter. Verify that the filters and the associated compo­
nents are clean. Also verify that they are functioning
effectively. This will minimize the amount of abra­ sive particles that enter the engine.

OFF-ROAD
(4WD)
OPERATION
After off-road (4WD) operation, inspect the under­
side of the vehicle. Inspect the:
• Tires
• Body structure
• Steering components
• Suspension components • Exhaust system
• Threaded fasteners

HARSH
SURFACE ENVIRONMENTS
After extended operation in harsh environments,
the brake drums, brake linings, and rear wheel bear­ ings should be inspected and cleaned. This will pre­
vent wear and erratic brake action.

ROUTINE MAINTENANCE
The following routine maintenance is recommended
on a monthly basis: TIRES—Inspect the tires for unusual wear/damage.
Determine if the inflation pressure is adequate for
the vehicle load. BATTERY—Inspect and clean the terminals.
Tighten the terminals if necessary. FLUIDS—Determine if the component fluid levels
are acceptable. Add fluid, if necessary. LIGHTS/ELECTRICAL—Test all the electrical sys­
tems in the vehicle for proper operation. It is also recommended that the engine oil and the
washer fluid level be determined at each fuel fill-up.

VEHICLE

Vehicles with a GVWR of 4 535 kg (10,000 lbs), or
more, are required to comply with Federal Exterior Noise Regulations (Fig. 2).

UNAUTHORIZED
DEFEAT
OF
NOISE
CONTROL COMPONENTS
Federal law prohibits removal, altering or other­
wise defeating any noise control component. This in­
cludes before or after the vehicle is in use. Federal
law also prohibits the use of a vehicle after a noise
control component is defeated.

REQUIRED MAINTENANCE/SERVICE
FOR
NOISE
CONTROL

The following maintenance is required after each
6-month or 9 600 km (6,000 miles) interval. This will
ensure that the vehicle noise control components are
operating properly.

EXHAUST SYSTEM
Inspect exhaust system for exhaust leaks and dam­
aged components. The exhaust hangers, clamps and
U-bolts should be attached and in good condition.
Burned or ruptured mufflers, damaged exhaust pipes should be replaced. Refer to Group 11—Exhaust Sys­
tem/Intake Manifold for service information.

AIR
FILTER
HOUSING/CANISTER
Inspect the air filter assembly for proper fit. Verify
the cover is securely attached to the housing/canis­
ter. Inspect all the air filter housing hoses for con­ nections. The gasket between the air filter housing and throttle body must be in good condition. The air
filter element should be clean and serviced according
to the maintenance schedule.

FUEL
REQUIREMENTS
GASOLINE
ENGINES
All engines require the use of unleaded gasoline to
reduce the effects of lead to the environment. Also unleaded fuel is necessary to prevent damage to the
catalytic converter/02 sensor. The fuel must have a
minimum octane rating of 87 based on the (R + M)/2
calculation method.

CLASSIFICATION
OF
LUBRICANTS
Lubricating fluids
and
chassis lubricants
are

to

by the:
• Society
of
Automotive Engineers
(SAE)

• American Petroleum Institute
(API)

• National Lubricating Grease Institute (NLGI)
ENGINE
OIL

SAE
VISCOSITY
GRADE
An
SAE
viscosity grade
is
used
to
specify
the
vis­
cosity
of
engine
oil. SAE 30
specifies
a
single viscos­
ity engine
oil.

Engine oils also have multiple viscosities. These
are specified with
a
dual
SAE
viscosity grade which
indicates
the
cold-to-hot temperature viscosity range (Fig.
3).

API
SERVICE
GRADE
The
API
Service Grade specifies
the
type
of
perfor­
mance
the
engine
oil is
intended
to
provide.
The API
Service Grade specifications also apply
to
energy con­
serving engine oils
(Fig. 3).

For maximum gasoline engine protection,
use API

Service Grade
SG,
SG/CD
or
SG/CE engine
oil.

For maximum Diesel engine protection,
use

API Service
CE or
SG/CE engine
oil.

GEAR LUBRICANTS A dual grade
is
also used
to
specify
the
viscosity
of

multi-purpose gear lubricants.
The
API
grade designation identifies gear lubri­
cants
in
terms
of
recommended usage.

J9200-86

(1) Engage the parking brake. Shift the automatic
transmission to PARK (if a manual transmission, shift to NEUTRAL).
(2) Turn off all lights, and all other electrical

loads.

(3)
Observe the battery condition indicator (Fig. 5).
If the battery condition indicator is light/bright col­
ored (or yellow), replace the battery. Do not attempt
to jump start an engine when the condition indi­
cator is light/bright colored (or yellow). If the
condition indicator is dark in the center (but without a green dot), proceed with connecting the jumper ca­

bles.

ENGINE BREAK-IN
After first starting a new engine, allow it to idle
for 15 seconds before shifting into a drive gear. Also:
• Drive the vehicle at varying speeds less than 88
km/h (55 mph) for the first 480 km (300 miles).
• Avoid fast acceleration and sudden stops.
• Do not drive at full-throttle for extended periods of
time
• Do not drive at constant speeds
• Do not idle the engine excessively A special break-in engine oil is not required. The
original engine oil installed is a high quality lubri­
cant. New engines tend to consume more fuel and oil un­
til after the break-in period has ended.

API SERWICE
GRADE
Use an engine oil that conforms to API Service
Grade S5 SG/CD or SG/CE. MOPAR®provides engine
oils that conform to all of these service grades.

SULFATED ASH—DIESEL ENGINES
Oils that contain an excessive amount of sulfated
ash can cause deposits to develop on Diesel engine
valves. These deposits can result in valve wear.

ACCEPTABLE
OIL
LEVEL
To maintain proper lubrication of an engine, the
engine oil must be maintained at an acceptable level.
For gasoline engines, the acceptable levels are indi­ cated between the ADD and
FULL
marks on oil
dip­
stick. For Diesel engines, the acceptable levels are
indicated between the L (low) and H
(high) marks
on
oil dipstick. The oil level should be checked periodically. The
vehicle should be on a level surface. Wait for
five
minutes after stopping the engine. For gasoline en­
gines,
add oil only when the level indicated on the
dipstick is at or below the ADD mark. For Diesel en­
gines,
add oil only when the level indicated on the
dipstick is between the L and H marks.
Never oper­
ate a Diesel
engine when
the oil
level
is below
the L mark. The distance between the L and H
marks represents 1.9L (2 Qts) engine oil.

CAUTION:
Do not
overfill
