TIRE TYPES
All Season Tires — If Equipped
All Season tires provide traction for all seasons
(Spring, Summer, Autumn, and Winter). Traction
levels may vary between different all season
tires. All season tires can be identified by the
M+S, M&S, M/S or MS designation on the tire sidewall. Use all season tires only in sets of four;
failure to do so may adversely affect the safety
and handling of your vehicle.
Summer Or Three Season Tires — If
Equipped

Summer tires provide traction in both wet and dry
conditions, and are not intended to be driven in
snow or on ice. If your vehicle is equipped with
Summer tires, be aware these tires are not
designed for Winter or cold driving conditions.
Install Winter tires on your vehicle when ambient
temperatures are less than 40°F (5°C) or if
roads are covered with ice or snow. For more
information, contact an authorized dealer.

Summer tires do not contain the all season
designation or mountain/snowflake symbol on
the tire sidewall. Use Summer tires only in sets
of four; failure to do so may adversely affect the
safety and handling of your vehicle.
Snow Tires
Some areas of the country require the use of
snow tires during the Winter. Snow tires can be
identified by a “mountain/snowflake” symbol
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 four; 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). For
speeds above 75 mph (120 km/h) refer to
original equipment or an authorized tire dealer
for recommended safe operating speeds,
loading and cold tire inflation pressures.
While studded tires improve performance on
ice, skid and traction capability on wet or dry
surfaces may be poorer than that of
non-studded tires. Some states prohibit
studded tires; therefore, local laws should be
checked before using these tire types.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 readings.
WARNING! (Continued)
WARNING!
Do not use Summer tires in snow/ice
conditions. You could lose vehicle control,
resulting in severe injury or death. Driving too
fast for conditions also creates the possibility
of loss of vehicle control.

Install on front/rear tires.
For a LT235/80R17E tire, use of a U-class
snow chain is recommended.
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 aggressive tread designs such
as those on all season type tires. Rotation will
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 clear -
ance between tires and other suspension
components, it is important that only trac-
tion 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.
Install device as tightly as possible and
then retighten after driving about ½ mile
(0.8 km). Autosock traction devices do not
require retightening.
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
instructions on the method of installation,
operating speed, and conditions for use.
Always use the suggested operating speed
of the device manufacturer if it is less than
30 mph (48 km/h).
Do not use traction devices on a compact
spare tire.
CAUTION! (Continued)

If you detect any stone chips or scratches in
the paint, touch them up immediately. The
cost of such repairs is considered the respon -
sibility of the owner.
If your vehicle is damaged due to a collision
or similar cause that destroys the paint and
protective coating, have your vehicle repaired
as soon as possible. The cost of such repairs
is considered the responsibility of the owner.
If you carry special cargo such as chemicals,
fertilizers, de-icer salt, etc., be sure that such
materials are well packaged and sealed.
If a lot of driving is done on gravel roads,
consider mud or stone shields behind each
wheel.
Use Mopar Touch Up Paint on scratches as
soon as possible. An authorized dealer has
touch up paint to match the color of your
vehicle.
Spray-On Bedliner – If Equipped
During ownership, the shine and luster of the
Spray-On Bedliner can fade from oxidation, road
dirt, heavy-duty hauling and hard water stains. Weathering and UV exposure will lead to fading,
dulling, and loss of gloss over time.
To help maintain the appearance of your
Spray-On Bedliner, the manufacturer
recommends you periodically rinse all loose dirt
from your truck bed and clean your truck at
least twice per year using the Mopar Spray-On
Bedliner Conditioner available at a local
authorized dealer.
To Help Maintain The Appearance Of Your
Spray-On Bedliner, Follow The Steps Below:


1. Rinse your truck bed out with water to remove any loose dirt and debris.

2. Mix a mild soap or detergent with water with a soft cloth or brush.
3. Rinse bedliner with water.
4. Once dry, apply a small amount of Mopar Spray-On Bedliner Conditioner to a moist
towel or sponge and wipe over the entire
surface of the truck bedliner. Spray-On Bedliners are chemically-resistant to
many different types of chemicals (including
gasoline, oil, hydraulic fluids) for short periods
of time. If a spill occurs on your Spray-On
Bedliner, rinse the truck out as soon as possible
to avoid permanent damage.
Repairing The Spray-On Bedliner
While extremely tough, it is possible to damage
a Spray-On Bedliner. One common condition is
when loading a heavy pallet and dragging that
pallet across the floor of the bed. If a nail or
sharp point is exposed under the weight of the
pallet a scratch or tear is possible. While not
covered by your new vehicle warranty, a
cosmetic fix to cover the metal exposed by the
scratch is required. To repair a tear or gouge,
follow the directions provided in the Mopar
Quick Repair Kit.
WARNING!
Do not use silicon-based protection products
to clean your bedliner. Silicon-based products
can become slippery and may result in
personal injury.

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.
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/or the “ABS Warning Light” during
brake use.
HYDRAULIC BRAKE ASSIST — IF
E
QUIPPED
The brake system power assist is provided by a
hydro-boost unit which shares fluid with the
power steering system. You may experience
some clicking or hissing noises from the
hydro-boost system during hard braking
conditions.
NOTE:
Under cold temperatures, pedal effort will be
higher than normal until the power steering fluid
reaches operating temperature.
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.
TORQUE SPECIFICATIONS
**Use only authorized dealer recommended
lug nuts/bolts and clean or remove any dirt or
oil before tightening.
