GETTING TO KNOW YOUR VEHICLE27
The Vehicle Security system is designed to
protect your vehicle. However, you can create
conditions where the system will give you a false
alarm. If one of the previously described arming
sequences has occurred, the Vehicle Security
system will arm regardless of whether you are in
the vehicle or not. If you remain in the vehicle
and open a door, the alarm will sound. If this
occurs, disarm the Vehicle Security system.
If the Vehicle Security system is armed and the
battery becomes disconnected, the Vehicle
Security system will remain armed when the
battery is reconnected; the exterior lights will
flash, and the horn will sound. If this occurs,
disarm the Vehicle Security system.
REARMING OF THE SYSTEM
If something triggers the alarm, and no action is
taken to disarm it, the Vehicle Security system
will turn the horn off after 29 seconds, five
seconds between cycles, and up to eight cycles
if the trigger remains active. The Vehicle
Security system will then rearm itself.
SECURITY SYSTEM MANUAL OVERRIDE
The Vehicle Security system will not arm if you
lock the doors using the manual door lock.

Non-Rolling Code Garage Door Opener Final
Steps

1. Push and hold the programmed
HomeLink® button and observe the
HomeLink® indicator light. If the
HomeLink® indicator light stays on
constantly, programming is complete.

2. Push the programmed HomeLink® button to confirm that the garage door opener
motor operates. If the garage door opener
motor does not operate, repeat the steps
from the beginning.PROGRAMMING HOMELINK® TO A
M
ISCELLANEOUS DEVICE
The procedure on how to program HomeLink®
to a miscellaneous device follows the same
procedure as programming to a garage door
opener Úpage 50. Be sure to determine if the
device has a rolling code, or non-rolling code
before beginning the programming process.
NOTE:
Canadian radio frequency laws require trans -
mitter signals to time-out (or quit) after several
seconds of transmission, which may not be long
enough for HomeLink® to pick up the signal
during programming. Similar to this Canadian
law, some U.S. gate operators are designed to
time-out in the same manner. The procedure
may need to be performed multiple times to
successfully pair the device to your HomeLink®
buttons.
REPROGRAMMING A SINGLE
H
OMELINK® BUTTON
To reprogram a single HomeLink® button that
has been previously trained, without erasing all
the channels, follow the procedure below. Be
sure to determine whether the new device you want to program the HomeLink® button to has
a Rolling Code, or Non-rolling Code.

1. Place the ignition in the ON/RUN position,
without starting the engine.

2. Push and hold the desired HomeLink® button until the HomeLink® Indicator light
begins to flash after 20 seconds. Do not
release the button.
3. Without releasing the button , proceed with
Step 2 in “Programming HomeLink® To A
Garage Door Opener” Ú page 50, and
follow all remaining steps.
CANADIAN/GATE OPERATOR
P
ROGRAMMING
For programming transmitters in Canada/
United States that require the transmitter
signals to “time-out” after several seconds of
transmission.
Canadian radio frequency laws require
transmitter signals to time-out (or quit) after
several seconds of transmission – which may
not be long enough for HomeLink to pick up the
signal during programming. Similar to this
Canadian law, some U.S. gate operators are
designed to time-out in the same manner.
WARNING!
Your motorized door or gate will open and
close while you are programming the
universal transceiver. Do not program the
transceiver if people or pets are in the path
of the door or gate.
Do not run your vehicle in a closed garage
or confined area while programming the
transceiver. Exhaust gas from your vehicle
contains Carbon Monoxide (CO) which is
odorless and colorless. Carbon Monoxide is
poisonous when inhaled and can cause you
and others to be severely injured or killed.

Power Outlet Fuse Locations

When the vehicle is turned off, be sure to
unplug any equipment as to not drain the
battery of the vehicle. All accessories connected
to the outlet(s) should be removed or turned off
when the vehicle is not in use to protect the
battery against discharge.POWER INVERTER — IF EQUIPPED
A 115 Volt (400 Watts Maximum) inverter may
be located inside the center console towards
the right hand side. 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.

Center Console Power Inverter Outlet

3 — F48 Fuse 10 A Red Port Power or Rear USB
(Charge Only)
WARNING!
To avoid serious injury or death:
Only devices designed for use in this type of
outlet should be inserted into any 12 Volt
outlet.
Do not touch with wet hands.
Close the lid when not in use and while
driving the vehicle.
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
discharge the battery even more quickly.
Only use these intermittently and with
greater caution.
After the use of high power draw accesso -
ries, 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.
CAUTION! (Continued)
