The power inverter is designed with built-in
overload protection. If the power rating of
150 Watts is exceeded, the power inverter
automatically shuts down. Once the elec-
trical device has been removed from the
outlet, the inverter should automatically
reset. To avoid overloading the circuit, check
the power ratings on electrical devices prior
to using the inverter.ROOF LUGGAGE RACK — IF
EQUIPPED
The load carried on the roof, when equipped
with a luggage rack, must not exceed 150 lbs
(68 kg), and it should be uniformly distrib -
uted over the cargo area.
Crossbars should always be used whenever
cargo is placed on the roof rack. Check the
straps frequently to be sure that the load
remains securely attached.
NOTE:
Crossbars can be purchased at an authorized
dealer through Mopar parts.
External racks do not increase the total load
carrying capacity of the vehicle. Be sure that
the total occupant and luggage load inside
the vehicle, plus the load on the luggage
rack, do not exceed the maximum vehicle
load capacity.
WARNING!
To avoid serious injury or death:
Do not insert any objects into the recep -
tacles.
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.
WARNING!
Cargo must be securely tied down before
driving your vehicle. Improperly secured
loads can fly off the vehicle, particularly at
high speeds, resulting in personal injury or
property damage. Follow the roof rack
cautions when carrying cargo on your roof
rack.
CAUTION!
To avoid damage to the roof rack and
vehicle, do not exceed the maximum roof
rack load capacity. Always distribute
heavy loads as evenly as possible and
secure the load appropriately.
Long loads, which extend over the wind -
shield, should be secured to both the
front and rear of the vehicle.
Place a blanket or other protection
between the surface of the roof and the
load.

Gross Vehicle Weight Rating (GVWR)
The Gross Vehicle Weight Rating (GVWR) is
the total permissible weight of your vehicle
including driver, passengers, vehicle,
options and cargo. The label also specifies
maximum capacities of front and rear axle
systems (GAWR). Total load must be limited
so GVWR and front and rear GAWR are not
exceeded.
Payload
The payload of a vehicle is defined as the
allowable load weight a truck can carry,
including the weight of the driver, all passen-
gers, options and cargo.
Gross Axle Weight Rating (GAWR)
The Gross Axle Weight Rating (GAWR) is the
maximum permissible load on the front and
rear axles. The load must be distributed in
the cargo area so that the GAWR of each axle
is not exceeded.
Each axle GAWR is determined by the
components in the system with the lowest
load carrying capacity (axle, springs, tires or
wheels). Heavier axles or suspension compo -nents sometimes specified by purchasers for
increased durability does not necessarily
increase the vehicle's GVWR.
Curb Weight
The curb weight of a vehicle is defined as the
total weight of the vehicle with all fluids,
including vehicle fuel, at full capacity condi
-
tions, and with no occupants or cargo loaded
into the vehicle. The front and rear curb
weight values are determined by weighing
your vehicle on a commercial scale before
any occupants or cargo are added.
Loading
The actual total weight and the weight of the
front and rear of your vehicle at the ground
can best be determined by weighing it when
it is loaded and ready for operation.
The entire vehicle should first be weighed on
a commercial scale to ensure that the GVWR
has not been exceeded. The weight on the
front and rear of the vehicle should then be
determined separately to be sure that the
load is properly distributed over the front and
rear axle. Weighing the vehicle may show
that the GAWR of either the front or rear
axles has been exceeded but the total load is
within the specified GVWR. If so, weight must be shifted from front to rear or rear to
front as appropriate until the specified
weight limitations are met. Store the heavier
items down low and be sure that the weight
is distributed equally. Stow all loose items
securely before driving.
Improper weight distributions can have an
adverse effect on the way your vehicle steers
and handles and the way the brakes operate.
CAUTION!
Do not load your vehicle any heavier than
the GVWR or the maximum front and rear
GAWR. If you do, parts on your vehicle can
break, or it can change the way your
vehicle handles. This could cause you to
lose control. Also overloading can shorten
the life of your vehicle.

high-speed vehicle operation. Refer to an
authorized tire dealer or original equipment
vehicle dealer for recommended safe oper-
ating speeds, loading and cold tire inflation
pressures.
Radial Ply 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 than a ¼ of an
inch (6 mm).
Consult an authorized tire dealer for tire
repairs 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 designed 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 capabilities and needs to be
replaced immediately. A run flat tire is not
repairable. When a run flat tire is changed after
driving with underinflated 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.
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).
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.

NOTE:
Wheel Valve Stem must be replaced as well
when installing new tires due to wear and
tear in existing tires.
Keep dismounted tires in a cool, dry place
with as little exposure to light as possible.
Protect tires from contact with oil, grease,
and gasoline.
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 pressures. The manufac-
turer strongly recommends that you use tires
equivalent to the originals in size, quality
and performance when replacement is
needed. Refer to the paragraph on “Tread
Wear Indicators” in this section. Refer to the
Tire and Loading Information placard or the
Vehicle Certification Label for the size desig -
nation 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 performance
characteristics, resulting in changes to
steering, handling, and braking of your
vehicle. This can cause unpredictable
handling and stress to steering 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 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.
