A vehicle safety certification label (Fig. 1) is at-
tached to every Jeep vehicle. The label certifies that
the vehicle conforms to all applicable Federal Motor
Vehicle Safety Standards. The label also lists:
²Gross vehicle weight rating (GVWR) and the gross
front and rear axle weight ratings (GAWR's) based on
a minimum tire rim size and a maximum cold tire
inflation pressure.
²Month and year of vehicle manufacture.
²Vehicle identification number (VIN).
²Type of vehicle.
²Month, day and hour (MDH) of final assembly.
The label is located on the driver-side door shut-
face.
VEHICLE IDENTIFICATION NUMBER (VIN) PLATE
The Vehicle Identification Number (VIN) plate islocated on the lower windshield fence near the left
A-pillar. The VIN contains 17 characters that provide
data concerning the vehicle. Refer to the VIN decod-
ing chart to determine the identification of a vehicle.
The Vehicle Identification Number is also imprinted

available for starting engines. Follow the manufac-
turer's instructions and observe the listed precau-
tions when involved in any engine starting
procedure.
HOISTING 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 Jeep vehicle (Fig. 2 and 3). Support the ve-
hicle in the raised position with jack stands at the
front and rear ends of the frame rails.
CAUTION: Do not attempt to lift a Jeep vehicle with
a floor jack positioned under:

lifting locations only (Fig. 2 and 3).
HOIST
A vehicle can be lifted with:
²A single-post, frame-contact hoist.
²A twin-post, chassis hoist.
²A ramp-type, drive-on hoist.
When a frame-contact type hoist is used, ver-
ify that the lifting pads are positioned properly
(Fig. 2 and 3).WARNING: THE HOISTING AND JACK LIFTING
POINTS PROVIDED ARE FOR A COMPLETE VEHI-
CLE. WHEN A CHASSIS OR DRIVETRAIN COMPO-
NENT IS REMOVED FROM A VEHICLE, THE
CENTER OF GRAVITY IS ALTERED MAKING SOME
HOISTING CONDITIONS UNSTABLE. PROPERLY
SUPPORT OR SECURE VEHICLE TO HOISTING DE-
VICE WHEN THESE CONDITIONS EXIST.
TOWING RECOMMENDATIONS
A vehicle equipped with SAE approved sling-type
towing equipment can be used to tow all Jeep vehi-
cles. When towing a 4WD vehicle using a wheel-lift
towing device, use a tow dolly under the opposite end
of the vehicle. A vehicle with flat-bed device can also
be used to transport a disabled vehicle (Fig. 4).
A wooden crossbeam may be required for proper
connection when using the sling-type, front-end tow-
ing method.
SAFETY PRECAUTIONS
²Secure loose and protruding parts.
²Always use a safety chain system that is indepen-
dent of the lifting and towing equipment.
²Do not allow towing equipment to contact the dis-
abled vehicle's fuel tank.
²Do not allow anyone under the disabled vehicle
while it is lifted by the towing device.

²Do not allow passengers to ride in a vehicle being
towed.
²Always observe state and local laws regarding tow-
ing regulations.²Do not tow a vehicle in a manner that could jeop-
ardize the safety of the operator, pedestrians or other
motorists.
²Do not attach tow chains, T-hooks, J-hooks, or a
tow sling to a bumper, steering linkage, drive shafts
or a non-reinforced frame hole.
GROUND CLEARANCE AND RAMP ANGLE
GROUND CLEARANCE
CAUTION: If vehicle is towed with wheels removed,
install lug nuts to retain brake drums.
A towed vehicle should be raised until lifted wheels
are a minimum 100 mm (4 in) from the ground. Be
sure there is adequate ground clearance at the oppo-
site end of the vehicle, especially when towing over
rough terrain or steep rises in the road. If necessary,
remove the wheels from the lifted end of the vehicle
and lower the vehicle closer to the ground, to in-
crease the ground clearance at the opposite end of
the vehicle. Install lug nuts on wheel attaching studs
to retain brake drums.
FLAT-BED TOWING RAMP ANGLE
If a vehicle with flat-bed towing equipment is used,
the approach ramp angle should not exceed 15 de-
grees.

ENGINE SUPPORTS
The general condition of the engine supports
should be inspected when engine compartment or un-
der vehicle service is performed.
INSPECTION
(1) Test the hardware that attaches the engine cyl-
inder block to the engine support brackets (Figs. 11
and 12) for the specified tightening torque.(2) Inspect the rubber in the engine support cush-
ions for softening and swelling. Slight surface deteri-
oration and wear at the ends will not affect the
functioning of an engine support.
ACCESSORY DRIVE BELT
Inspect and adjust drive belts at the interval de-
scribed in the Lubrication and Maintenance Sched-
ules. Refer to General Information section of this
group. For proper inspection and adjustment proce-
dures, see Group 7, Cooling System.
EXHAUST SYSTEM
The exhaust system should be inspected when un-
der vehicle service is performed or as specified in the
Lubrication and Maintenance Schedules.
INSPECTION
When inspecting an exhaust system, inspect for
cracked or loose joints, stripped screw/bolt threads,
corrosion damage, and worn or broken hangers
(Slight cracking in rubber isolator or hanger is ac-
ceptable). Replace all components that are corroded
or damaged. Do not attempt repair. Also, inspect for
the following obvious conditions and correct as neces-
sary:
²Exhaust system leaks, damage, misalignment.
²Contact with body panels metal or the frame.
²Catalytic 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.
For proper service procedures see Group 11, Ex-
haust System and Intake Manifold.
AIR-CONDITIONER COMPRESSOR
LUBRICANT AND REFRIGERANT
The lubricant level in the air-conditioner compres-
sor should be checked if there are indications that oil
was lost. Loss of lubricating oil usually accompanies
a loss of refrigerant.
