CHECK TRAILER WIRING
On vehicles with the Integrated
Trailer Brake Control (ITBC) system,
this message may display and a
chime may sound when one of the
following conditions exists:
.A trailer with electric brakes
becomes disconnected from the
vehicle.
‐ If the disconnect occurs while
the vehicle is stopped, this
message clears itself after a
short time.
‐ If the disconnect occurs while
the vehicle is moving, this
message stays on until the
ignition is turned off.
.There is a short in the wiring to
the electric trailer brakes.
When this message displays, power
is no longer available to the trailer
brakes.
As soon as it is safe to do so,
carefully pull the vehicle over to the
side of the road and turn the ignition
off. Check the wiring connection to
the trailer and turn the ignition back
on. This message clears if the trailer
is reconnected. This message also
clears if you acknowledge it. If this
message still displays, either the
vehicle or the trailer needs service.
See your dealer.

Make sure the hand-held transmitter
has a new battery for quick and
accurate transmission of the
radio-frequency signal.
Programming the Universal
Remote System
For questions or help programming
the Universal Remote system, call
1-800-355-3515 or see
www.homelink.com.
Programming involves
time-sensitive actions, and may time
out causing the procedure to be
repeated.
To program up to three devices:
1. Hold the end of the hand-heldtransmitter about 3 to 8 cm (1 to
3 in) away from the Universal
Remote system buttons with the
indicator light in view. The
hand-held transmitter was
supplied by the manufacturer of
the garage door opener receiver. 2. At the same time, press and
hold both the hand-held
transmitter button and one of the
three Universal Remote system
buttons to be used to operate
the garage door. Do not release
either button until the indicator
light goes from a slow to a rapid
flashing light. Then release both
buttons.
Some garage door openers may
require substitution of Step 2
with the procedure under “Radio
Signals for Canada and Some
Gate Operators” later in this
section.
3. Press and hold the newly programmed Universal Remote
system button for five seconds
while watching the indicator light
and garage door activation.
.If the indicator light stays on
continuously or the garage
door moves when the button
is pressed, then programming is complete.
There is no need to complete
Steps 4–6.
.If the indicator light does not
come on or the garage door
does not move, a second
button press may be
required. For a second time,
press and hold the newly
programmed button for
five seconds. If the light
stays on or the garage door
moves, programming is
complete.
.If the indicator light blinks
rapidly for two seconds, then
changes to a solid light and
the garage door does not
move, continue with
programming Steps 4–6.

Learn or Smart Button
4. After completing Steps 1–3, locate the Learn or Smart button
inside the garage on the garage
door opener receiver. The name
and color of the button may vary
by manufacturer.
5. Press and release the Learn or Smart button. Step 6 must be
completed within 30 seconds of
pressing this button.
6. Inside the vehicle, press and hold the newly programmed
Universal Remote system button
for two seconds and then
release it. If the garage door
does not move or the lamp on
the garage door opener receiver does not flash, press and hold
the same button a second time
for two seconds, then release it.
Again, if the door does not move
or the garage door lamp does
not flash, press and hold the
same button a third time for
two seconds, then release it.
The Universal Remote system
should now activate the
garage door.
Repeat the process for
programming the two remaining
buttons.
Radio Signals for Canada and
Some Gate Operators
For questions or programming help,
call 1-800-355-3515 or see
www.homelink.com.
Canadian radio-frequency laws and
some U.S. gate operators require
transmitter signals to time out or quit
after several seconds of
transmission. This may not be long enough for the Universal Remote
system to pick up the signal during
programming.
If the programming did not work,
replace Step 2 under
“Programming
the Universal Remote System” with
the following:
Press and hold the Universal
Remote system button while
pressing and releasing the
hand-held transmitter button every
two seconds until the signal has
been successfully accepted by the
Universal Remote system. The
Universal Remote system indicator
light will flash slowly at first and then
rapidly. Proceed with Step 3 under
“Programming the Universal Remote
System” to complete.

to pass. It works even if the
headlamps are in the automatic
position.
To use it, pull the turn signal lever
toward you, then release it.
If the headlamps are in the
automatic position or on low beam,
the high-beam headlamps will turn
on. They will stay on as long as you
hold the lever toward you. The
high-beam indicator on the
instrument cluster will come on.
Release the lever to return to
normal operation.
Daytime Running
Lamps (DRL)
DRL can make it easier for others to
see the front of the vehicle during
the day. Fully functional DRL are
required on all vehicles first sold in
Canada.
The DRL system comes on when
the following conditions are met:
.The ignition is on.
.The exterior lamp control is
in AUTO.
.The transmission is not in
P (Park).
.The light sensor determines it is
daytime.
When the DRL system is on, only
the DRL are on. The taillamps,
sidemarker lamps, instrument panel
lights, and other lamps will not
be on.
When it begins to get dark, the
automatic headlamp system
switches from DRL to the
headlamps.
To turn off the DRL, turn the exterior
lamp control to the off position and
then release. For vehicles first sold
in Canada, off will only work when
the vehicle is in P (Park).
Automatic Headlamp
System
When the exterior lamp control is
set to AUTO and it is dark enough
outside, the headlamps come on
automatically.
There is a light sensor on top of the
instrument panel. Do not cover the
sensor, otherwise the headlamps
will come on when they are not
needed.
The system may also turn on the
headlamps when driving through a
parking garage or tunnel.
