GETTING TO KNOW YOUR VEHICLE 39
NOTE:
Canadian radio frequency laws require transmitter
s i
gnals 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,
w
ithout starting the engine.

2. Push and hold the desired HomeLink® button u
ntil the HomeLink® Indicator light begins to
flash after 20 seconds. Do not release the
button.

rage Door Opener” 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 (RF) laws require
t r

ansmitter 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 US gate operators are
designed to time-out in the same manner.
It may be helpful to unplug the device during the
c y

cling process to prevent possible overheating of
the garage door or gate motor.

1. P lace the ignition in the ON/RUN position.

2
. P lace the hand-held transmitter 1 to 3
inches
(3
to 8 cm) away from the HomeLink® button
you wish to program while keeping the
HomeLink® indicator light in view.

3. Continue to press and hold the HomeLink® bu
tton, while you press and release (cycle) your
hand-held transmitter every two seconds until
HomeLink® has successfully accepted the
frequency signal. The indicator light will flash
slowly and then rapidly when fully trained.

4. Watch for the HomeLink® indicator to change f
lash rates. When it changes, it is programmed. It may take up to 30 seconds or
longer in rare cases. The garage door may
open and close while you are programming.
5. P ress and hold the programmed HomeLink®
b
utton and observe the indicator light.
NOTE:
If the indicator light stays on constantly,
programming is complete and the garage
door/device should activate when the
HomeLink® button is pressed.

To program the two remaining HomeLink®
buttons, repeat each step for each remaining
button. DO NOT erase the channels.

If you unplugged the garage door opener/device
f or

programming, plug it back in at this time.
Reprogramming A Single HomeLink® Button
(C
anadian/Gate Operator)
To reprogram a channel that has been previously
tr
ained, follow these steps:

1. Place the ignition in the ON/RUN position.

2
. P ress and hold the desired HomeLink® button
u
ntil the indicator light begins to flash after 20
seconds. Do not release the button.
3. W ithout releasing the button, proceed with
“
Canadian/Gate Operator Programming”
step 2 and follow all remaining steps

OPERATING TIPS
NOTE:
Refer to the chart at the end of this section for
s u
ggested control settings for various weather
conditions.
Summer Operation
The engine cooling system must be protected with
a high-quality antifreeze coolant to provide proper
corrosion protection and to protect against engine
overheating. OAT coolant (conforming to
MS.90032) is recommended.
Winter Operation
To ensure the best possible heater and defroster
performance, make sure the engine cooling
system is functioning properly and the proper
amount, type, and concentration of coolant is
used. Use of the Air Recirculation mode during
Winter months is not recommended, because it
may cause window fogging.
Vacation/Storage
For information on maintaining the Climate Control
system when the vehicle is being stored for an
extended period of time, see
Ú page 242.
Window Fogging
Vehicle windows tend to fog on the inside in mild,
rainy, and/or humid weather. To clear the
windows, select Defrost or Mix mode and increase
the front blower speed. Do not use the
Recirculation mode without A/C for long periods,
as fogging may occur.
Outside Air Intake
Make sure the air intake, located directly in front of
the windshield, is free of obstructions, such as
leaves. Leaves collected in the air intake may
reduce airflow, and if they enter the air distribution
box, they could plug the water drains. In Winter
months, make sure the air intake is clear of ice,
slush, and snow.
Cabin Air Filter
The Climate Control system filters out dust and
pollen from the air. Contact an authorized dealer to
service your cabin air filter, and to have it replaced
when needed.
