Programming the HomeLink®
Transmitter
Do not use the HomeLink®Transmitter with any garage
door opener that does not have the “stop and reverse”
feature. This includes any garage door opener model
manufactured before April 1, 1982. If you have a newer
garage door opener with rolling codes, please be
sure to follow steps 6 through 8 to complete the
programming of your HomeLink
®Transmitter.
Read the instructions completely before attempting to
program the HomeLink
®Transmitter. Because of
the steps involved, it may be helpful to have another
person available to assist you in programming the
transmitter.
Keep the original transmitter for use in other vehicles as
well as for future HomeLink
®programming. It is also
recommended that upon the sale of the vehicle, the
programmed HomeLink
®buttons should be erased for
security purposes. Refer to “Erasing HomeLink®Buttons”
or, for assistance, contact HomeLink®on the internet at:
www.homelink.com or by calling 1-800-355-3515.
Be sure that people and objects are clear of the
garage door or gate operator you are programming.
When programming a garage door, it is advised to park
outside of the garage.It is recommended that a new battery be installed in
your hand-held transmitter for quicker and more
accurate transmission of the radio frequency.
Your vehicle’s engine should be turned off while
programming the transmitter. Follow these steps to
program up to three channels:
1. Press and hold down the two outside buttons,
releasing only when the indicator light begins to
ash, after 20 seconds. Do not hold down the
buttons for longer than 30 seconds and do not
repeat this step to program a second and/or third
transmitter to the remaining two HomeLink
®buttons.
2. Position the end of your hand-held transmitter about
1 to 3 inches (3 to 8 cm) away from the HomeLink
®
buttons while keeping the indicator light in view.
3. Simultaneously press and hold both the desired
button on HomeLink
®and the hand-held transmitter
button. Do not release the buttons until Step 4
has been completed.
Some entry gates and garage door openers may
require you to substitute Step 3 with the procedure
noted in “Gate Operator and Canadian
Programming” later in this section.

Tow/Haul Mode
Your vehicle may be equipped with a tow/haul feature.
Tow/haul is designed to assist while your vehicle is
pulling a large or heavy load or trailer. Tow/haul is most
useful while pulling such a load in rolling terrain at
speeds less than 55 mph (88 km/h), in stop-and-go
traffic, or when you need improved low-speed control,
such as when parking. The purpose of the tow/haul
mode is to do the following:
Reduce the frequency and improve the predictability
or transmission shifts,
provide the same solid shift feel while pulling a
heavy load as while the vehicle is unloaded, and
improve control of vehicle speed while requiring less
throttle pedal activity.
Press the button on the end of the shift lever to turn
tow/haul mode on and off. While activated, the indicator
light on the instrument panel will be on. Tow/haul
mode will turn off automatically when the ignition is
turned off. SeeTow/Haul Mode Light on page 3-35.Tow/haul mode is most effective when the vehicle and
load combined weight is at least 75 percent of the
vehicle’s Gross Vehicle Weight Rating (GVWR) and the
maximum trailer weight rating for the vehicle. See
“Weight of the Trailer” later in this section.
Driving with tow/haul activated without a heavy load will
cause reduced fuel economy and unpleasant engine
and transmission driving characteristics, but will
not cause damage.
Weight of the Trailer
How heavy can a trailer safely be?
It depends on how you plan to use your rig. For
example, speed, altitude, road grades, outside
temperature and how much your vehicle is used to pull
a trailer are all important. And, it can also depend
on any special equipment that you have on your vehicle.
The following chart shows how much your trailer can
weigh, based upon your vehicle model and options.
Maximum trailer weight is calculated assuming the driver
and one passenger are in the tow vehicle and it has
all the required trailering equipment. The weight
of additional optional equipment, passengers and cargo
in the tow vehicle must be subtracted from the
maximum trailer weight. The weight of the trailer tongue
also affects the maximum trailer weight. See “ Weight
of the Trailer Tongue ” later in this section.
