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 (refer to the paragraph on
ªTread Wear Indicatorsº). Refer to the ªTire and Loading
Informationº 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, handling, and ride of your vehicle. We recommend
that you contact your original equipment or an autho-
rized tire dealer with any questions you may have on tire
specifications or capability.WARNING!
²Do not use a tire, wheel size or rating other than
that specified for your vehicle. Some combina-
tions of unapproved tires and wheels may change
suspension dimensions and performance charac-
teristics, resulting in changes to steering, han-
dling, and braking of your vehicle. This can cause
unpredictable handling and stress to steering and
suspension components. 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.
²Never 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.
²Failure to equip your vehicle with tires having
adequate speed capability can result in sudden
tire failure and loss of vehicle control.
226 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:
²Fast tire wear.
²Uneven tire wear, such as feathering and one-sided
wear.
²Vehicle 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.
TIRE CHAINS
If driving conditions require tire chains for your vehicle,
use only chains that meet SAE type ªClass Sº specifica-
tions. In addition, only install tire chains on 245/45ZR20
size tires. Contact you local dealership or tire dealer for
these size tires.

CAUTION!
To avoid damage to your vehicle or tires, observe the
following precautions:
²Because of restricted chain clearance between
tires and other suspension components, it is im-
portant that only chains in good condition are
used. Broken chains can cause serious damage.
Stop the vehicle immediately if noise occurs that
could indicate chain breakage. Remove the dam-
aged parts of the chain before further use.
²Install chains on the rear wheels as tightly as
possible and then retighten after driving about1¤2mile (0.8 km).
²Do not exceed 30 mph (48 km/h).
²Drive cautiously and avoid severe turns and large
bumps, especially with a loaded vehicle.
²Use on Rear Wheels only.
²Do not drive for prolonged period on dry pavement.
²Observe the tire chain manufacturer's instructions
on the method of installation, operating speed,
and conditions for use. Always use the lower
suggested operating speed of the chain manufac-
turer if different from the speed recommended by
the manufacture.
NOTE:In order to avoid damage to tires, chains, and
your vehicle do not drive for a prolonged period of time
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 if both
the chain manufacturer and vehicle manufacture suggest
a maximum speed. This notice applies to all chain
traction devices, including link and cable (radial) chains.
SNOW TIRES
Some areas of the country require the use of snow tires
during winter. Standard tires are of the all season type
and satisfy this requirement as indicated by the M+S
designation on the tire sidewall.
If you need snow tires, select tires equivalent in size and
type to the original equipment tires. Use snow tires only
in sets of 4, failure to do so may adversely affect the
safety and handling of your vehicle.
Snow tires generally have lower speed ratings than what
was originally equipped with your vehicle and should not
be operated at sustained speeds over 75 mph (120 km/h).
228 STARTING AND OPERATING

²Month Day and Hour of Manufacture (MDH)
The bar code allows a computer scanner to read the
Vehicle Identification Number (VIN).
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your vehicle.
This includes driver, passengers, and cargo. The total
load must be limited so that you do not exceed the
GVWR.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum capacity of the front and rear
axles. Distribute the load over the front and rear axles
evenly. Make sure that you do not exceed either front or
rear GAWR.
WARNING!
Because the front wheels steer the vehicle, it is
important that you do not exceed the maximum front
or rear GAWR. A dangerous driving condition can
result if either rating is exceeded. You could lose
control of the vehicle and have an accident.
Overloading
The load carrying components (axle, springs, tires,
wheels, etc.) of your vehicle will provide satisfactory
service as long as you do not exceed the GVWR and front
and rear GAWR.
The best way to figure out the total weight of your
vehicle is to weigh it when it is fully loaded and ready for
operation. Weigh it on a commercial scale to insure that it
is not over the GVWR.
Figure out the weight on the front and rear of the vehicle
separately. It is important that you distribute the load
evenly over the front and rear axles.
Overloading can cause potential safety hazards and
shorten useful service life. Heavier axles or suspension
components do not necessarily increase the vehicle's
GVWR.
Loading
To load your vehicle properly, first figure out its empty
weight, axle by axle and side by side. Store heavier items
down low and be sure you distribute their weight as
evenly as possible. Stow all loose items securely before

Refer to the ªMaintenance Scheduleº in this manual for
the recommended air conditioning filter replacement
intervals.
Power Steering Ð Fluid Check
Checking the power steering fluid level at a defined
service interval is not required. The fluid should only be
checked if a leak is suspected, abnormal noises are
apparent, and/or the system is not functioning as antici-
pated. Coordinate inspection efforts through a certified
DaimlerChrysler Dealership.
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 manufacturer's recommended
power steering fluid.
If necessary, add fluid to restore to the proper indicated
level. With a clean cloth, wipe any spilled fluid from allsurfaces. Refer to ªFluids, Lubricants, and Genuine
Partsº in this section for the correct fluid type.
Front & Rear Suspension Ball Joints
The suspension ball joints should be inspected for exter-
nal leakage or damage when other maintenance is per-
formed.
Steering Linkage
The tie rod end ball joints should be inspected for
external leakage or damage when other maintenance is
performed.
Body Lubrication
Locks and all body pivot points, including seat tracks,
door hinges, trunk hinges, and hood hinges, should be
lubricated periodically to assure quiet, easy operation
and to protect against rust and wear. Prior to the appli-
cation 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 also be given to hood latching compo-
nents to insure proper function. When performing other
underhood services, the hood latch, release mechanism,
and safety catch should be cleaned and lubricated.
276 MAINTAINING YOUR VEHICLE

²Inspect the battery, and clean, and tighten the termi-
nals as required.
²Check the fluid levels of coolant reservoir and brake
master cylinder, and add as needed.
²Check all lights and all other electrical items for correct
operation.
²Check rubber seals on each side of the radiator for
proper fit.
At Each Oil Change
²
Change the engine oil filter.
²Inspect the exhaust system.
