rity Alarm is active.
Before You Begin Programming HomeLink 
Be sure that your vehicle is parked outside of the garage
before you begin programming. For more efficient programming and accurate transmis-
sion of the radio-frequency signal it is recommended that
a new battery be placed in the hand-held transmitter of
the device that is being programmed to the HomeLink

system.
Erase all channels before you begin programming. To
erase the channels place the ignition in the ON/RUN
position and press and hold the two outside HomeLink 
buttons (I and III) for up 20 seconds or until the red
indicator flashes.
NOTE:
•Erasing all channels should only be performed when
programming HomeLink for the first time. Do not
erase channels when programming additional buttons.
•If you have any problems, or require assistance, please
call toll-free 1–800–355–3515 or, on the Internet at

ELECTRICAL POWER OUTLETS
Your vehicle is equipped with 12 Volt (13 Amp) power
outlets that can be used to power cellular phones, small
electronics and other low powered electrical accessories.
The power outlets are marked as either a “key” or a
“battery” symbol to indicate how the outlet is powered.
Power outlets labeled with a “key” are powered when
the ignition switch is in the ON or ACC position, while the outlets marked with a “battery” are connected di-
rectly to the battery and powered at all times.
NOTE:
•All accessories connected to the “battery” powered
outlets should be removed or turned off when the
vehicle is not in use to protect the battery against
discharge.
•To ensure proper operation a MOPAR
knob and
element must be used.
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 damage
not covered by your New Vehicle Limited Warranty.

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 inter-
mittently and with greater caution.
•After the use of high power draw accessories, 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
generator to recharge the vehicle’s battery.
POWER INVERTER — IF EQUIPPED
There is a 115 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, electron-
ics and other low power devices requiring power up to
150 Watts. Certain high-end video games, such as Play-
station3 and XBox360 will exceed this power limit, as will
most power tools.

NOTE:To prevent excessive battery drain, use the rear
window defroster only when the engine is operating.
CAUTION!
Failure to follow these cautions can cause damage to
the heating elements:
•Use care when washing the inside of the rear
window. Do not use abrasive window cleaners on
the interior surface of the window. Use a soft cloth
and a mild washing solution, wiping parallel to
the heating elements. Labels can be peeled off
after soaking with warm water.
•Do not use scrapers, sharp instruments, or abra-
sive window cleaners on the interior surface of the
window.
•Keep all objects a safe distance from the window.
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 authorized
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 increase 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.
