CAUTION!
• Power outlets are designed for accessory
plugs only. Do not insert any other object
in the power outlets as this will damage
the outlet and blow the fuse. Improper
use of the power outlet can cause dam-
age not covered by your New Vehicle
Limited Warranty.
WARNING!
To avoid serious injury or death:
• Do not insert any objects into the
receptacles.
• Do not touch with wet hands.
• Close the lid when not in use.
• If this outlet is mishandled, it may
cause an electric shock and failure.
CAUTION!
•Many accessories that can be plugged in
draw power from the vehicle's battery, even
when not in use (i.e., cellular phones,
etc.). Eventually, if plugged in long
enough, the vehicle's battery will discharge
sufficiently to degrade battery life and/or
prevent the engine from starting.
• Accessories that draw higher power (i.e.,
coolers, vacuum cleaners, lights, etc.),
will degrade the battery even more
quickly. Only use these intermittently
and with greater caution.
• After the use of high power draw acces-
sories, or long periods of the vehicle not
being started (with accessories still
plugged in), the vehicle must be driven a
sufficient length of time to allow the
alternator to recharge the vehicle's
battery.
• Power outlets are designed for accessory
plugs only. Do not hang any type of
accessory or accessory bracket from the
plug. Improper use of the power outlet
can cause damage.
ROOF LUGGAGE RACK — IF
EQUIPPED
The crossbars and siderails are designed to
carry the weight on vehicles equipped with a
luggage rack. The load must not exceed
150 lbs (68 kg), and should be uniformly
distributed over the luggage rack crossbars.
NOTE:
If not equipped with crossbars, your autho-
rized dealer can order and install Mopar
crossbars built specifically for this roof rack
system.
Distribute cargo weight evenly on the roof
rack crossbars. The roof rack does not in-
crease the total load carrying capacity of the
vehicle. Be sure the total load of cargo inside
the vehicle plus that on the external rack
does not exceed the maximum vehicle load
capacity.
To move the crossbars, loosen the attach-
ments, located at the upper edge of each
crossbar, approximately eight turns using the
anti-theft wrench provided with the Mopar
crossbars. Then, move the crossbar to the
desired position, keeping the crossbars par-

allel to the rack frame. Once the crossbar is in
the desired position, retighten the with the
wrench to lock the crossbar into position.
NOTE:
• To help control wind noise when the cross-
bars are not in use, place the front and rear
crossbars approximately 24 inches (61 cm)
apart. Optimal noise reduction can then be
achieved by adjusting the front crossbar
forward or aft using increments of 1 inch
(2.5 cm).
• If any cargo (or any metallic object) is
placed over the satellite radio antenna (if
equipped), you may experience interrup-
tion of satellite radio reception. For im-
proved satellite radio reception, avoid plac-
ing the rear crossbar over the satellite radio
antenna.
WARNING!
Cargo must be securely tied down before
driving your vehicle. Improperly secured
loads can fly off the vehicle, particularly at
WARNING!
high speeds, resulting in personal injury or
property damage. Follow the roof rack cau-
tions when carrying cargo on your roof
rack.
CAUTION!
• To prevent damage to the roof of your
vehicle, do not carry any loads on the
roof rack without the crossbars installed.
The load should be secured and placed
on top of the crossbars, not directly on
the roof. If it is necessary to place the
load on the roof, place a blanket or some
other protection between the load and
the roof surface.
• To avoid damage to the roof rack and
vehicle, do not exceed the maximum
roof rack load capacity of 150 lb (68 kg).
Always distribute heavy loads as evenly
as possible and secure the load
appropriately.
CAUTION!
• Long loads which extend over the wind-
shield, such as wood panels or surf-
boards, or loads with large frontal area
should be secured to both the front and
rear of the vehicle.
• Place a blanket or other protection be-
tween the surface of the roof and the
load.
• Travel at reduced speeds and turn cor-
ners carefully when carrying large or
heavy loads on the roof rack. Wind
forces, due to natural causes or nearby
truck traffic, can add sudden upward lift
to a load. This is especially true on large
flat loads and may result in damage to
the cargo or your vehicle.
• The use of Sport Mode is not recom-
mended when using the Roof Luggage
Rack to carry a load.

Service FCW Warning
If the system turns off, and the instrument
cluster displays:
• ACC/FCW Unavailable Service Required
• Cruise/FCW Unavailable Service Required
This indicates there is an internal system
fault. Although the vehicle is still drivable
under normal conditions, have the system
checked by an authorized dealer.
Tire Pressure Monitor System (TPMS)
NOTE:
For vehicles equipped with run flat tires —
when the TPMS indicates a tire pressure of
14 psi (96 kPa) or lower, always check tire
pressure and replace the tire at the first
opportunity. At inflation pressure of/or below
14 psi (96 kPa) the tire is in the run-flat
mode of operation. In this condition, it is
recommended a vehicle maximum speed of
50 mph (80 km/h) for a maximum distance of
50 miles (80 km). The manufacturer does not
recommend using the run flat feature while
driving a vehicle loaded at full capacity or
towing a trailer.The Tire Pressure Monitoring System (TPMS)
will warn the driver of a low tire pressure
based on the vehicle recommended cold tire
pressure.
The tire pressure will vary with temperature
by about 1 psi (7 kPa) for every 12°F (6.5°C).
This means that when the outside tempera-
ture decreases, the tire pressure will de-
crease. Tire pressure should always be set
based on cold inflation tire pressure. This is
defined as the tire pressure after the vehicle
has not been driven for at least three hours, or
driven less than 1 mile (1.6 km) after a
three-hour period.Refer to “Tires” in “Servic-
ing And Maintenance” for information on how to
properly inflate the vehicle’s tires.The tire
pressure will also increase as the vehicle is
driven - this is normal and there should be no
adjustment for this increased pressure.
The TPMS will warn the driver of a low tire
pressure if the tire pressure falls below the
low pressure warning threshold for any rea-
son, including low temperature effects, or
natural pressure loss through the tire.The TPMS will continue to warn the driver of
low tire pressure as long as the condition
exists, and will not turn off until the tire
pressure is at or above recommended cold
tire pressure. Once the low tire pressure
warning has been illuminated, the tire pres-
sure must be increased to the recommended
cold tire pressure in order for the TPMS
Warning Light to be turned off.
NOTE:
When filling warm tires, the tire pressure may
need to be increased up to an additional 4 psi
(28 kPa) above the recommended cold plac-
ard pressure in order to turn the TPMS Warn-
ing Light off.
The system will automatically update and the
TPMS Warning Light will extinguish once the
updated tire pressures have been received.
The vehicle may need to be driven for up to
10 minutes above 15 mph (24 km/h) to
receive this information.
For example, your vehicle has a recom-
mended cold (parked for more than three
hours) tire pressure of 33 psi (227 kPa). If
the ambient temperature is 68°F (20°C) and
the measured tire pressure is 28 psi
103

CAUTION!
After inspecting or adjusting the tire pres-
sure, always reinstall the valve stem cap.
This will prevent moisture and dirt from
entering the valve stem, which could dam-
age the valve stem.
Inflation pressures specified on the placard
are always “cold tire inflation pressure”. Cold
tire inflation pressure is defined as the tire
pressure after the vehicle has not been driven
for at least three hours, or driven less than
1 mile (1.6 km) after sitting for a minimum of
three hours. The cold tire inflation pressure
must not exceed the maximum inflation pres-
sure molded into the tire sidewall.
Check tire pressures more often if subject to
a wide range of outdoor temperatures, as tire
pressures vary with temperature changes.
Tire pressures change by approximately 1 psi
(7 kPa) per 12°F (7°C) of air temperature
change. Keep this in mind when checking
tire pressure inside a garage, especially in the
Winter.Example: If garage temperature = 68°F
(20°C) and the outside temperature = 32°F
(0°C) then the cold tire inflation pressure
should be increased by 3 psi (21 kPa), which
equals 1 psi (7 kPa) for every 12°F (7°C) for
this outside temperature condition.
Tire pressure may increase from 2 to 6 psi
(13 to 40 kPa) during operation. DO NOT
reduce this normal pressure build up or your
tire pressure will be too low.
Tire Pressures For High Speed Operation
The manufacturer advocates driving at safe
speeds and within posted speed limits.
Where speed limits or conditions are such
that the vehicle can be driven at high speeds,
maintaining correct tire inflation pressure is
very important. Increased tire pressure and
reduced vehicle loading may be required for
high-speed vehicle operation. Refer to an
authorized tire dealer or original equipment
vehicle dealer for recommended safe operat-
ing speeds, loading and cold tire inflation
pressures.
WARNING!
High speed driving with your vehicle under
maximum load is dangerous. The added
strain on your tires could cause them to
fail. You could have a serious collision. Do
not drive a vehicle loaded to the maximum
capacity at continuous speeds above
75 mph (120 km/h).
Loading
The vehicle maximum load on the tire must
not exceed the load carrying capacity of the
tire on your vehicle. You will not exceed the
tire's load carrying capacity if you adhere to
the loading conditions, tire size, and cold tire
inflation pressures specified on the Tire In-
formation placard.
NOTE:
Under a maximum loaded vehicle condition,
gross axle weight ratings (GAWRs) for the
front and rear axles must not be exceeded.

WARNING!
Overloading of your tires is dangerous.
Overloading can cause tire failure, affect
vehicle handling, and increase your stop-
ping distance. Use tires of the recom-
mended load capacity for your vehicle.
Never overload them.
Radial Ply Tires
WARNING!
Combining radial ply tires with other types
of tires on your vehicle will cause your
vehicle to handle poorly. The instability
could cause a collision. Always use radial
ply tires in sets of four. Never combine
them with other types of tires.
Tire Repair
If your tire becomes damaged, it may be
repaired if it meets the following criteria:
• The tire has not been driven on when flat.
• The damage is only on the tread section of
your tire (sidewall damage is not repair-
able).• The puncture is no greater thana¼ofan
inch (6 mm).
Consult an authorized tire dealer for tire re-
pairs and additional information.
Damaged Run Flat tires, or Run Flat tires that
have experienced a loss of pressure should be
replaced immediately with another Run Flat
tire of identical size and service description
(Load Index and Speed Symbol). Replace the
tire pressure sensor as well as it is not de-
signed to be reused.Run Flat Tires — If Equipped
Run Flat tires allow you the capability to drive
50 miles (80 km) at 50 mph (80 km/h) after
a rapid loss of inflation pressure. This rapid
loss of inflation is referred to as the Run Flat
mode. A Run Flat mode occurs when the tire
inflation pressure is of/or below 14 psi
(96 kPa). Once a Run Flat tire reaches the
run flat mode it has limited driving capabili-
ties and needs to be replaced immediately. A
Run Flat tire is not repairable. When a run flat
tire is changed after driving with underin-flated tire condition, please replace the TPM
sensor as it is not designed to be reused when
driven under run flat mode (14 psi (96 kPa))
condition.
NOTE:
TPM Sensor must be replaced after driving
the vehicle on a flat tire condition.
It is not recommended driving a vehicle
loaded at full capacity or to tow a trailer while
a tire is in the run flat mode.
See the tire pressure monitoring section for
more information.Tire Spinning
When stuck in mud, sand, snow, or ice con-
ditions, do not spin your vehicle's wheels
above 30 mph (48 km/h) or for longer than
30 seconds continuously without stopping.
Refer to “Freeing A Stuck Vehicle” in “In
Case Of Emergency” for further information.
WARNING!
Fast spinning tires can be dangerous.
Forces generated by excessive wheel

cators” in this section. 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.
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 an authorized
tire dealer or original equipment dealer with
any questions you may have on tire specifica-
tions 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, load rating,
or speed rating other than that specified
for your vehicle. Some combinations of
unapproved tires and wheels may
change suspension dimensions and per-
WARNING!
formance characteristics, resulting in
changes to steering, handling, and brak-
ing of your vehicle. This can cause un-
predictable handling and stress to steer-
ing and suspension 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.
• Never use a tire with a smaller load index
or capacity, other than what was origi-
nally equipped on your vehicle. Using a
tire with a smaller load index could re-
sult 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 speedom-
eter and odometer readings.
Tire Types
All Season Tires — If Equipped
All Season tires provide traction for all sea-
sons (Spring, Summer, Fall, 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
