GMC SIERRA DENALI 2004 Owners Manual

Press the right or left side of the mirror control to fold or
unfold the mirrors. You may notice the mirror glass
adjust as the mirrors fold in; this is normal. The mirror
glass will reposition itself once the mirrors are unfolded.
If the mirrors are accidentally folded/unfolded manually,
they may shake or ¯utter at normal driving speeds
and may not stay in the unfolded position. If this
happens, you will need to reset the mirrors. See
ªResetting the Power Foldaway Mirrorsº next.
Resetting the Power Foldaway Mirrors
You will need to reset the power foldaway mirrors if the
following occurs:
·They are accidentally manually folded/unfolded.
·The mirrors will not stay in the unfolded position.
·The mirrors shake and ¯utter at normal driving
speeds.
To reset the power foldaway mirrors, fold and unfold
then at least three times using the mirror controls. This
will reset them to their normal detent position.
Outside Automatic Dimming Mirror
The driver's outside mirror will adjust for the glare of any
headlamps behind you. This feature is controlled by
the on and off settings on the electrochromic mirror.See ªElectrochromic Mirror Operationº under
Automatic
Dimming Rearview Mirror with OnStarž, Compass
and Temperature Display on page 2-31.
Outside Curb View Assist Mirrors
If your vehicle has the optional memory package
you may have this feature.
The vehicle's mirrors are capable of performing the curb
view assist mirror function. This feature will cause the
passenger's and/or driver's mirror to tilt to a preselected
position when the vehicle is in REVERSE (R). This
feature may be useful in allowing you to view the curb
when you are parallel parking. When the vehicle is
shifted out of REVERSE (R) and a short delay
has occurred, the passenger's and/or driver's mirror will
return to its original position.
To change the preselected tilt position, adjust the
mirrors to the desired position while the vehicle is in
REVERSE (R). When the vehicle is shifted out of
REVERSE (R), this new position is saved in memory as
the tilt position.
You may be able to enable/disable this feature through
the Driver Information Center. See
Driver Information
Center (DIC) on page 3-46.

Outside Convex Mirror
Your passenger's side mirror is convex. A convex
mirror's surface is curved so you can see more from the
driver's seat.
{CAUTION:
A convex mirror can make things (like other
vehicles) look farther away than they really are.
If you cut too sharply into the right lane, you
could hit a vehicle on your right. Check your
inside mirror or glance over your shoulder
before changing lanes.
Outside Heated Mirrors
The outside rearview mirrors with this option have a
defrost mode.
To turn on the defrost feature, press the rear window
defogger button. See ªRear Window Defoggerº

Programming the HomeLinkž
Transmitter
Do not use the HomeLinkžTransmitter with any garage
door opener that does not have the ªstop and reverseº
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
žTransmitter.
Read the instructions completely before attempting to
program the HomeLink
žTransmitter. 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
žprogramming. It is also
recommended that upon the sale of the vehicle,
the programmed HomeLink
žbuttons should be erased
for security purposes. Refer to ªErasing HomeLinkž
Buttonsº or, for assistance, contact HomeLinkžon 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
žbuttons.
2. Position the end of your hand-held transmitter about
1 to 3 inches (3 to 8 cm) away from the HomeLink
ž
buttons while keeping the indicator light in view.
3. Simultaneously press and hold both the desired
button on HomeLink
žand 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 ªGate Operator and Canadian
Programmingº later in this section.
2-39

4. The indicator light will ¯ash slowly at ®rst and then
rapidly after HomeLinkžsuccessfully receives the
frequency signal from the hand-held transmitter.
Release both buttons.
5. Press and hold the newly-trained HomeLink
žbutton
and observe the indicator light.
If the indicator light stays on constantly,
programming is complete and your device should
activate when the HomeLink
žbutton is pressed and
released.
To program the remaining two HomeLink
žbuttons,
begin with Step 2 under ªProgramming HomeLinkž.º
Do not repeat Step 1 as this will erase all of the
programmed channels.
If the indicator light blinks rapidly for two seconds
and then turns to a constant light, continue with
Steps 6 through 8 following to complete the
programming of a rolling-code equipped device
(most commonly, a garage door opener).6. Locate in the garage, the garage door opener
receiver (motor-head unit). Locate the ªLearnº
or ªSmartº button. This can usually be found where
the hanging antenna wire is attached to the
motor-head unit.
7. Firmly press and release the ªLearnº or ªSmartº
button. The name and color of the button may
vary by manufacturer.
You will have 30 seconds to start Step 8.
8. Return to the vehicle. Firmly press and hold the
programmed HomeLink
žbutton for two seconds,
then release. Repeat the press/hold/release
sequence a second time, and depending on the
brand of the garage door opener (or other rolling
code device), repeat this sequence a third time
to complete the programming.
HomeLink
žshould now activate your rolling-code
equipped device.
To program the remaining two HomeLink
žbuttons,
begin with Step 2 of ªProgramming HomeLinkž.º Do not
repeat Step 1.
2-40

Gate Operator and Canadian
Programming
Canadian radio-frequency laws require transmitter
signals to ªtime outº or quit after several seconds of
transmission. This may not be long enough for
HomeLink
žto pick up the signal during programming.
Similarly, some U.S. gate operators are manufactured to
ªtime outº in the same manner.
If you live in Canada, or you are having difficulty
programming a gate operator by using the
ªProgramming HomeLink
žº procedures (regardless of
where you live), replace Step 3 under ªProgramming
HomeLink
žº with the following:
Continue to press and hold the HomeLink
žbutton while
you press and release every two seconds (cycle)
your hand-held transmitter until the frequency signal has
been successfully accepted by HomeLink
ž. The
indicator light will ¯ash slowly at ®rst and then rapidly.
Proceed with Step 4 under ªProgramming HomeLink
žº
to complete.
Using HomeLinkž
Press and hold the appropriate HomeLinkžbutton for at
least half of a second. The indicator light will come
on while the signal is being transmitted.
Erasing HomeLinkžButtons
To erase programming from the three buttons do the
following:
1. Press and hold down the two outside buttons until
the indicator light begins to ¯ash, after 20 seconds.
2. Release both buttons. Do not hold for longer than
30 seconds.
HomeLink
žis now in the train (learning) mode and can
be programmed at any time beginning with Step 2
under ªProgramming HomeLink
ž.º
Individual buttons can not be erased, but they can be
reprogrammed. See ªReprogramming a Single
HomeLink
žButtonº next.
2-41

Reprogramming a Single HomeLinkž
Button
To program a device to HomeLinkžusing a HomeLinkž
button previously trained, follow these steps:
1. Press and hold the desired HomeLink
žbutton.
Do not release the button.
2. The indicator light will begin to ¯ash after
20 seconds. While still holding the HomeLink
ž
button, proceed with Step 2 under ªProgramming
HomeLinkž.º
Resetting Defaults
To reset HomeLinkžto default settings do the following:
1. Hold down the two outside buttons for about
20 seconds until the indicator light begins to ¯ash.
2. Continue to hold both buttons until the HomeLink
ž
indicator light turns off.
