GETTING TO KNOW YOUR VEHICLE

CAUTION!

• Do not exceed the maximum power of 160 Watts (13

Amps) at 12 Volts. If the 160 Watt (13 Amp) power
rating is exceeded the fuse protecting the system will
need to be replaced.

• 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 damage
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 suffi-
ciently 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 bat-
tery even more quickly. Only use these intermit-
tently and with greater caution.

• After the use of high power draw accessories, or long

periods of the vehicle not being started (with acces-
sories 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.

Power Inverter — If Equipped

There is a 115 or 230 Volt, 150 Watt inverter outlet located

on the back of the center console to convert DC current to

AC current. This outlet can power cellular phones, elec-

tronics and other low power devices requiring power up to

150 Watts. Certain high-end video game consoles will

exceed this power limit, as will most power tools.

The power inverter is designed with built-in overload

protection. If the power rating of 150 Watts is exceeded, the

power inverter will automatically shut down. Once the

electrical device has been removed from the outlet, the

inverter should automatically reset. If the power rating

exceeds approximately 170 Watts, the power inverter may

have to be reset manually.

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.

Auxiliary Switches — If Equipped

Four auxiliary switches located in the lower switch bank of

the instrument panel can be used to power various electri-

cal devices. You have the ability to configure the function-

ality of the auxiliary switches via the Uconnect settings. All

switches can be configured for setting the switch type

operation to latching or momentary, power source of either

battery or ignition, and ability to hold last state across key

cycles.

NOTE:

Holding last state conditions are met when switch

type is set to latching and power source is set to ignition.
For more information, refer to “Uconnect Settings” in

“Multimedia.”
The auxiliary switches control relays that power four blunt

cut wires located in the interior passenger outboard foot

well area and on the right side of the engine compartment

near the battery.

In addition to the four auxiliary switch wires, a fused

battery wire and ignition wire are also located in the

interior, in the passenger outboard foot well area.
A kit of splices and heat shrink tubing are provided with

the auxiliary switches to aid in the connection/installation

of your electrical devices.

ROOF LUGGAGE RACK — IF EQUIPPED

NOTE:

Roof rack applications are for Hard Top models

ONLY

The load carried on the roof, when equipped with a

luggage rack, must not exceed 100 lbs (45 kg), this includes

the weight of the crossbars, and it should be uniformly

distributed 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!

Cargo must be securely tied down before driving your
vehicle. Improperly secured loads can fly off the ve-
hicle, particularly at high speeds, resulting in personal
injury or property damage. Follow the roof rack cau-
tions 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 windshield, such

as wood panels or surfboards, 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.

(Continued)

CAUTION! (Continued)

• Travel at reduced speeds and turn corners 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 loads. This is espe-
cially true on large flat loads and may result in
damage to the cargo or your vehicle.

• Load should always be secured to cross bars first,

with tie down loops used as additional securing
points if needed. Tie loops are intended as supple-
mentary tie down points only. Do not use ratcheting
mechanisms with the tie loops. Check the straps
frequently to be sure that the load remains securely
attached.
