wear and correct cold tire inflation pressures. 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
“Tread Wear Indicator.” Refer to the Tire and Loading
Information placard or the Vehicle Certification Label for
the size designation of your tire. The Load Index and
Speed Symbol for your tire will be found on the original
equipment tire sidewall. See the Tire Sizing Chart ex-
ample found in the Tire Safety Information section of this
manual for more information relating to the Load Index
and Speed Symbol of a tire.
It is recommended to replace the two front tires or two
rear tires as a pair. Replacing just one tire can seriously
affect your vehicle’s handling. If you ever replace a
wheel, make sure that the wheel’s specifications match
those of the original wheels.
It is recommended you contact your authorized tire
dealer or original equipment dealer with any questions
you may have on tire specifications or capability. Failure
to use equivalent replacement tires may adversely affect
the safety, handling, and ride of your vehicle.
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 sus-
pension dimensions and performance characteris-
tics, resulting in changes to steering, handling, and
braking of your vehicle. This can cause unpredict-
able handling and stress to steering and suspen-
sion components. You could lose control and have
a collision resulting in serious injury or death. Use
only the tire and wheel sizes with load ratings
approved for your vehicle.

WARNING!(Continued)
•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 a collision.
•Failure to equip your vehicle with tires having
adequate speed capability can result in sudden tire
failure and loss of vehicle control.
CAUTION!
Replacing original tires with tires of a different size
may result in false speedometer and odometer read-
ings.
TIRE CHAINS (TRACTION DEVICES)
Use of traction devices require sufficient tire-to-body
clearance. Follow these recommendations to guard
against damage.
•Traction device must be of proper size for the tire, as
recommended by the traction device manufacturer.
•Install on front tires only
•Due to limited clearance, the following traction de-
vices are recommended:
Front Wheel Drive (FWD) Models
•Original equipment 215/60R17 and 225/55R18 tire
sizes are not chainable.
•The use of 7mm snow chains is permitted with the use
of 215/60R16 tires.

Four Wheel Drive (4WD) Non-Trailhawk Models with-
out a Two-Speed Power Takeoff Unit
•Original equipment 215/60R17 and 225/55R18 tire
sizes are not chainable.
•The use of 9mm snow chains is permitted with the use
of 215/60R16 tires.
Four Wheel Drive (4WD) Non-Trailhawk Models with a
Two-Speed Power Takeoff Unit
•The use of 7mm snow chains is permitted with the use
of 215/60R17 and 225/55R18 tires.
Four Wheel Drive (4WD) Trailhawk Models
•The use of 9mm snow chains is permitted with the use
of 215/60R17 tires.
CAUTION!
•Use on Front Tires Only
•Damage to Front Wheel Drive (FWD) Models may
result if tire chains or traction devices are used with
original equipment size tires.
•Damage to Four Wheel Drive (4WD) Models with-
out a Two-Speed Power Takeoff Unit may result if
tire chains or traction devices are used with origi-
nal equipment size tires.
•Damage to Four Wheel Drive (4WD) Trailhawk
Models may result if tire chains or traction devices
are used with original equipment size tires.
WARNING!
Using tires of different size and type (M+S, Snow)
between front and rear axles can cause unpredictable
handling. You could lose control and have a collision.

damage to the power transfer unit. Tire rotation
schedule should be followed to balance tire wear.
VEHICLE STORAGE
If the vehicle should remain stationary for more than a
month, observe the following precautions:
•Park your vehicle in a covered, dry and possibly airy
location the windows open slightly;
•Check that the Electric Park Brake is not engaged.
•Disconnect the negative (-) terminal from the battery
