Spare Tire Matching Original Equipped Tire And Wheel
— If Equipped
Your vehicle may be equipped with a spare tire and wheel
equivalent in look and function to the original equipment
tire and wheel found on the front or rear axle of your vehicle.
This spare tire may be used in the tire rotation for your
vehicle. If your vehicle has this option, refer to an authorized
tire dealer for the recommended tire rotation pattern.
Compact Spare Tire — If Equipped
The compact spare is for temporary emergency use only.
You can identify if your vehicle is equipped with a compact
spare by looking at the spare tire description on the Tire and
Loading Information Placard located on the driver’s side
door opening or on the sidewall of the tire. Compact spare
tire descriptions begin with the letter “T” or “S” preceding
the size designation. Example: T145/80D18 103M.
T, S = Temporary Spare Tire
Since this tire has limited tread life, the original equipment
tire should be repaired (or replaced) and reinstalled on your
vehicle at the first opportunity.
Do not install a wheel cover or attempt to mount a conven-
tional tire on the compact spare wheel, since the wheel is designed specifically for the compact spare tire. Do not
install more than one compact spare tire and wheel on the
vehicle at any given time.
Collapsible Spare Tire — If Equipped
The collapsible spare is for temporary emergency use only.
You can identify if your vehicle is equipped with a collaps
-
ible spare by looking at the spare tire description on the Tire
and Loading Information Placard located on the driver’s side
door opening or on the sidewall of the tire.
Collapsible spare tire description example: 165/80-17 101P.
Since this tire has limited tread life, the original equipment
tire should be repaired (or replaced) and reinstalled on your
vehicle at the first opportunity.
WARNING!
Compact and collapsible spares are for temporary
emergency use only. With these spares, do not drive
more than 50 mph (80 km/h). Temporary use spares have
limited tread life. When the tread is worn to the tread
wear indicators, the temporary use spare tire needs to be
replaced. Be sure to follow the warnings, which apply to
your spare. Failure to do so could result in spare tire
failure and loss of vehicle control.

installed to the vehicle. Inflate the collapsible tire using the
electric air pump before lowering the vehicle.
Do not install a wheel cover or attempt to mount a conven-
tional tire on the collapsible spare wheel, since the wheel is
designed specifically for the collapsible spare tire.
Full Size Spare — If Equipped
The full size spare is for temporary emergency use only. This
tire may look like the originally equipped tire on the front or
rear axle of your vehicle, but it is not. This spare tire may
have limited tread life. When the tread is worn to the tread
wear indicators, the temporary use full size spare tire needs
to be replaced. Since it is not the same as your original equip -ment tire, replace (or repair) the original equipment tire and
reinstall on the vehicle at the first opportunity.
Limited Use Spare — If Equipped
The limited use spare tire is for temporary emergency use
only. This tire is identified by a label located on the limited
use spare wheel. This label contains the driving limitations
for this spare. This tire may look like the original equipped
tire on the front or rear axle of your vehicle, but it is not.
Installation of this limited use spare tire affects vehicle
handling. Since it is not the same as your original equipment
tire, replace (or repair) the original equipment tire and rein
-
stall on the vehicle at the first opportunity.
WARNING!
Compact and Collapsible spares are for temporary
emergency use only. With these spares, do not drive
more than 50 mph (80 km/h). Temporary use spares have
limited tread life. When the tread is worn to the tread
wear indicators, the temporary use spare tire needs to be

your spare. Failure to do so could result in spare tire
failure and loss of vehicle control.
WARNING!
Limited use spares are for emergency use only.
Installation of this limited use spare tire affects vehicle
handling. With this tire, do not drive more than the
speed listed on the limited use spare wheel. Keep
inflated to the cold tire inflation pressures listed on your
Tire and Loading Information Placard located on the
driver’s side B-Pillar or the rear edge of the driver’s side
door. Replace (or repair) the original equipment tire at
the first opportunity and reinstall it on your vehicle.
Failure to do so could result in loss of vehicle control.

Use of traction devices require sufficient tire-to-body clear-
ance. Follow these recommendations to guard against
damage.
• Traction device must be of proper size for the tire, as recommended by the traction device manufacturer. Please follow the table below for proper tire size, chain type,
and axle recommendations:
CAUTION!
If your vehicle is equipped with these specialty wheels,
DO NOT USE wheel cleaners, abrasives, or polishing
compounds. They will permanently damage this finish

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.
CAUTION!
To avoid damage to your vehicle or tires, observe the
following precautions:
• Because of restricted traction device clearance between tires and other suspension components, it is important
that only traction devices in good condition are used.
Broken devices can cause serious damage. Stop the
vehicle immediately if noise occurs that could indicate
device breakage. Remove the damaged parts of the
device before further use.

Tire Rotation Recommendations
Tires on the front and rear axles of vehicles operate at
different loads and perform different steering, driving, and
braking functions. For these reasons, they wear at unequal
rates.
These effects can be reduced by timely rotation of tires. The
benefits of rotation are especially worthwhile with aggres-
sive tread designs such as those on all season type tires. Rota -tion will increase tread life, help to maintain mud, snow and
wet traction levels and contribute to a smooth, quiet ride.
Refer to the “Maintenance Plan” for the proper maintenance
intervals. More frequent rotation is permissible if desired.
The reasons for any rapid or unusual wear should be
corrected prior to rotation being performed.
The suggested rotation method is the “rearward cross”
shown in the following diagram. This rotation pattern does
not apply to some directional tires that must not be reversed.
Tire Rotation (Rearward Cross)
• Install device as tightly as possible and then retighten
after driving about ½ mile (0.8 km).
• Do not exceed 30 mph (48 km/h).
• Drive cautiously and avoid severe turns and large bumps, especially with a loaded vehicle.
• Do not drive for a prolonged period on dry pavement.
• Observe the traction device manufacturer’s instruc -
tions on the method of installation, operating speed,
and conditions for use. Always use the suggested oper -
ating speed of the device manufacturer’s if it is less
than 30 mph (48 km/h).
• Do not use traction devices on a compact spare tire. CAUTION!

Cleaning Plastic Instrument Cluster Lenses
The lenses in front of the instruments in this vehicle are
molded in clear plastic. When cleaning the lenses, care must
be taken to avoid scratching the plastic.
1. Clean with a wet soft cloth. A mild soap solution may beused, but do not use high alcohol content or abrasive
cleaners. If soap is used, wipe clean with a clean damp
cloth.
2. Dry with a soft cloth.
Leather Parts
Mopar Total Clean is specifically recommended for leather
upholstery.
Your leather upholstery can be best preserved by regular
cleaning with a damp soft cloth. Small particles of dirt can act
as an abrasive and damage the leather upholstery and
should be removed promptly with a damp cloth. Stubborn
soils can be removed easily with a soft cloth and Mopar Total
Clean. Care should be taken to avoid soaking your leather
upholstery with any liquid. Please do not use polishes, oils,
cleaning fluids, solvents, detergents, or ammonia-based
cleaners to clean your leather upholstery. Application of a
leather conditioner is not required to maintain the original
condition. NOTE:
If equipped with light colored leather, it tends to show any
foreign material, dirt, and fabric dye transfer more so than
darker colors. The leather is designed for easy cleaning, and
FCA recommends Mopar Total Clean leather cleaner applied
on a cloth to clean the leather seats as needed.Glass Surfaces
All glass surfaces should be cleaned on a regular basis with
Mopar Glass Cleaner, or any commercial household-type
glass cleaner. Never use an abrasive type cleaner. Use
caution when cleaning the inside rear window equipped
with electric defrosters or windows equipped with radio
antennas. Do not use scrapers or other sharp instruments
that may scratch the elements.
When cleaning the rear view mirror, spray cleaner on the
towel or cloth that you are using. Do not spray cleaner
directly on the mirror.
CAUTION!
Do not use Alcohol and Alcohol-based and/or Ketone
based cleaning products to clean leather upholstery, as
damage to the upholstery may result. 7

IDENTIFICATION DATA
Vehicle Identification Number
The Vehicle Identification Number (VIN) is found on the left
front corner of the instrument panel, visible through the
windshield. This number also appears on the vehicle frame
etched on right hand center rail, as well as the Automobile
Information Disclosure Label affixed to a window on your
vehicle, the vehicle registration and title.Vehicle Identification Number
NOTE:
It is illegal to remove or alter the VIN.
BRAKE SYSTEM
If power assist is lost for any reason (for example, repeated
brake applications with the engine off), the brakes will still
function. However, you will experience a substantial
increase in braking effort to stop the vehicle.
If either the front or rear hydraulic system loses normal
braking capability, the remaining system will still function
with some loss of overall braking effectiveness. This will be
evident by increased pedal travel during application, greater
pedal force required to slow or stop, and activation of the
“Brake Warning Light” and the “ABS Warning Light” (if
equipped) during brake use.
WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to ensure that
the wheel is properly mounted to the vehicle. Any time a
wheel has been removed and reinstalled on the vehicle, the
lug nuts/bolts should be torqued using a properly calibrated
torque wrench using a high quality six sided (hex) deep wall
socket.
