NOTE:
Only use this transceiver with a garage door opener that has
a “stop and reverse” feature as required by federal safety
standards. This includes most garage door opener models
manufactured after 1982. Do not use a garage door opener
without these safety features. Call toll-free 1-800-355-3515 or,on the Internet at HomeLink.com for safety information or
assistance.
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 transmission
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.
To erase the channels, place the ignition in the ON/RUN
position, and push and hold the two outside HomeLink
buttons (I and III) for up to 20 seconds or until the orange
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 Home-
Link.com for information or assistance.
WARNING!
• Your motorized door or gate will open and close while you are programming the universal transceiver. Do not
program the transceiver if people, pets or other objects
are in the path of the door or gate. Only use this trans -
ceiver with a garage door opener that has a “stop and
reverse” feature as required by Federal safety stan -
dards. This includes most garage door opener models
manufactured after 1982. Do not use a garage door
opener without these safety features.
• Vehicle exhaust contains carbon monoxide, a dangerous gas. Do not run your vehicle in the garage
while programming the transceiver. Exhaust gas can
cause serious injury or death.

consists of two cup wells for rear passenger convenience.Rear Cup WellsElectrical Power Outlets
The auxiliary 12 Volt (13 Amp) power outlet can provide
power for in-cab accessories designed for use with the stan -
dard “cigar lighter” plug. The 12 Volt power outlets and 5
Volt (2.5 Amp) USB Port (Charge Only) have a cap attached
to the outlet indicating “12V DC,” together with either a key
symbol, battery symbol, or USB symbol.
A key symbol indicates that the key must be in the ON/RUN
or ACC positions for the outlet to provide power. The battery
symbol indicates that the outlet is connected to the battery,
and can provide power at all times.
CAUTION!

• Do not exceed the maximum power of 160 Watts (13 Amps) at 12 Volts. If the 160 Watts (13 Amps) 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.

Power Inverter — If Equipped
If equipped, a 115 Volt (400 Watts Maximum) inverter may
be located inside the center console towards the right hand
side, just under the Wireless Charging Pad (if equipped).
This inverter can power cellular phones, electronics andother low power devices requiring power up to 400 Watts.
Certain high-end video game consoles exceed this power
limit, as will most power tools.
Center Console Power Inverter Outlet
There is also a second 115 Volt (400 Watts Maximum) power
inverter located on the rear of the center console. This
inverter can power cellular phones, electronics and other low
power devices requiring power up to 400 Watts. Certain
high-end video game consoles exceed this power limit, as
will most power tools.
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 discharge the battery
even more quickly. Only use these intermittently and
with greater caution.
• After the use of high power draw accessories, or long periods of the vehicle not being started (with accesso -
ries still plugged in), the vehicle must be driven a suffi -
cient length of time to allow the generator to recharge
the vehicle's battery.
