Replacement Tires
The tires on your new vehicle provide a balance of many
characteristics. They should be inspected regularly for
wear and correct cold tire inflation pressure. The manu-
facturer strongly recommends that you use tires equiva-
lent to the originals in size, quality and performance
when replacement is needed (see the paragraph on tread
wear indicators). Refer to the Tire and Loading Informa-
tion placard for the size designation of your tire. The
service description and load identification will be found
on the original equipment tire. Failure to use equivalent
replacement tires may adversely affect the safety, han-
dling, and ride of your vehicle. We recommend that you
contact your original equipment or an authorized tire
dealer with any questions you may have on tire specifi-
cations or capability.WARNING!
•Do not use a tire, wheel size or rating other than that
specified for your vehicle. Some combinations of
unapproved tires and wheels may change suspen-
sion dimensions and performance characteristics,
resulting in changes to steering, handling, and brak-
ing of your vehicle. This can cause unpredictable
handling and stress to steering and suspension com-
ponents. You could lose control and have an accident
resulting in serious injury or death. Use only the tire
and wheel sizes with load ratings approved for your
vehicle.
•Never use a tire with a smaller load index or capacity,
other than what was originally equipped on your
vehicle. Using a tire with a smaller load index could
result in tire overloading and failure. You could lose
control and have an accident.
•Failure to equip your vehicle with tires having
adequate speed capability can result in sudden tire
failure and loss of vehicle control.
240 STARTING AND OPERATING

CAUTION!
Replacing original tires with tires of a different size
may result in false speedometer and odometer read-
ings.
Alignment And Balance
Poor suspension alignment may result in:
•Fast tire wear.
•Uneven tire wear, such as feathering and one-sided
wear.
•Vehicle pull to right or left.
Tires may also cause the vehicle to pull to the left or right.
Alignment will not correct this condition. See your dealer
for proper diagnosis.Improper alignment will not cause vehicle vibration.
Vibration may be a result of tire and wheel out-of-
balance. Proper balancing will reduce vibration and
avoid tire cupping and spotty wear.
SUPPLEMENTAL TIRE PRESSURE INFORMATION
A light load vehicle condition is defined as two passen-
gers {150 lbs (68 kg) each} plus 200 lbs (91kg) of cargo.
Cold tire inflation pressures for a lightly loaded vehicle
will be found on a “Supplemental Tire Pressure Inflation”
label located on the face of the driver’s door or in the Tire
Information Pressures pamphlet in the glove box.

TIRE CHAINS
Use “Class S” chains only on the rear tires on Dakota
trucks, or other traction aids that meet SAE Type “S”
specifications.
NOTE:Chains must be the proper size for the vehicle,
as recommended by the chain manufacturer.CAUTION!
To avoid damage to your vehicle, tires or chains, observe the
following precautions:
•Because of limited chain clearance between tires and other
suspension components, it is important that only chains in
good condition are used. Broken chains can cause serious
vehicle damage. Stop the vehicle immediately if noise
occurs that could suggest chain breakage. Remove the
damaged parts of the chain before further use.
•Install chains as tightly as possible and then retighten after
driving about 1/2 mile (0.8 km).
•Do not exceed 45 mph (72 km/h).
•Drive cautiously and avoid severe turns and large bumps,
especially with a loaded vehicle.
•Do not install tire chains on front wheels of 4x2 vehicles.
•Do not drive for a prolonged period on dry pavement.
•Observe the tire chain manufacturer’s instructions on
method of installation, operating speed, and conditions for
usage. Always use the lower suggested operating speed of
the chain manufacturer if different than the speed recom-
mended by the manufacturer.

Rating (GAWR) front and rear, and Vehicle Identification
Number (VIN). A Month-Day-Hour (MDH) number is
included on this label and shows the Month, Day, and
Hour of manufacture. The bar code that appears on the
bottom of the label is your Vehicle Identification Number
(VIN).
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total permissible weight of your vehicle
including driver, passengers, vehicle, options, and cargo.
The label also specifies maximum capacities of front and
rear axle systems. Total load must be limited so that
GVWR is not exceeded.
Payload
The payload of a vehicle is defined as the allowable load
weight a truck can carry including the weight of the
driver, all passengers, options, and cargo.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum permissible load on the front
and rear axles. The load must be distributed in the cargo
area so that the GAWR of each axle is not exceeded.
Each axle GAWR is determined by the component in the
system with the lowest load carrying capacity (axle,
springs, tires, or wheels).
Heavier axles or suspension components sometimes
specified by purchasers for increased durability do not
necessarily increase the vehicle’s GVWR.
Tire Size
This is the minimum allowable tire size for your vehicle.
Replacement tires must be equal to the load capacity of
this tire size.
Rim Size
This is the rim size that is appropriate for the tire size
listed.

•Donotinterconnect the hydraulic brake system of
your vehicle with that of the trailer. This could cause
inadequate braking and possible personal injury.
•Trailer brakes are recommended for trailers over 1,000
lbs (454 kg) and required for trailers in excess of 2,000
lbs. (907 kg).
•Use an approved trailer harness and connector. If a
hitch is ordered, the proper wiring will be provided.
•When hauling cargo or towing a trailer, do not over-
load your vehicle or trailer. Overloading can cause a
loss of control, poor performance or damage to brakes,
axle, engine, transmission, steering, suspension, chas-
sis structure or tires.
•Make certain that the load is secured in the trailer and
will not shift during travel. When trailering cargo that
cannot be fully secured, dynamic load shifts can occur
that may be difficult for the driver to control.
•All trailer hitches should be professionally installed on
your vehicle.
•Safety chains must always be used between your
vehicle and trailer.
•Connect trailer lighting and brakes using factory har-
nesses only. Do not cut or splice any wiring to the
brake circuits.
Trailer and Tongue Weight
Gross Trailer Weight (GTW) means the maximum allow-
able weight of the trailer plus the weight of all cargo and
equipment loaded on the trailer when in actual under-
way towing condition. The recommended way to mea-
sure GTW is to put your fully loaded trailer on a vehicle
scale. The entire weight of the trailer must be supported
by the scale.

WARNING!
Fluid level should be checked on a level surface and
with the engine off to prevent injury from moving
parts and to insure accurate fluid level reading. Do
not overfill. Use only manufacturers recommended
power steering fluid.
If necessary, add fluid to restore to the proper indicated
level. With a clean cloth, wipe any spilled fluid from all
surfaces. Refer to Recommended Fluids, Lubricants, and
Genuine Parts for correct fluid type.
Front Suspension Ball Joints
The ball joints and seals should be inspected whenever
the vehicle is serviced for other reasons. Damaged seals
should be replaced to prevent leakage or contamination
of the grease.
Drive Shaft Constant Velocity Joints
All four wheel drive models are equipped with four
constant velocity joints. Periodic lubrication of these
joints is not required. However, the joint boot should be
inspected for external leakage or damage periodically. If
external leakage or damage is evident, the joint boot and
grease should be replaced immediately. Continued op-
eration could result in failure of the joint due to water
and dirt contamination of the grease. This would require
complete replacement of the joint assembly. Refer to the
Service Manual for the detailed replacement procedure.
Body Lubrication
Locks and all body pivot points, including such items as
seat tracks, doors and hood hinges, should be lubricated
periodically to assure quiet, easy operation and to protect
against rust and wear. Prior to the application of any
lubricant, the parts concerned should be wiped clean to
remove dust and grit; after lubricating excess oil and
grease should be removed. Particular attention should
