2010 GMC SIERRA DENALI lights

When the System Does Not Seem To
Work Properly
The rear vision camera system might not work properly
or display a clear image if:
.The RVC is turned off. See“Turning the Rear
Camera System On or Off” earlier in this section.
.It is dark.
.The sun or the beam of headlights is shining
directly into the camera lens.
.Ice, snow, mud, or anything else builds up on the
camera lens. Clean the lens, rinse it with water,
and wipe it with a soft cloth.
.The back of the vehicle is in an accident, the
position and mounting angle of the camera can
change or the camera can be affected. Be sure to
have the camera and its position and mounting
angle checked at your dealer/retailer. The rear vision camera system display in the rearview
mirror may turn off or not appear as expected due to
one of the following conditions. If this occurs the left
indicator light on the mirror will flash.
.A slow flash may indicate a loss of video signal,
or no video signal present during the reverse cycle.
.A fast flash may indicate that the display has been
on for the maximum allowable time during a
reverse cycle, or the display has reached an Over
Temperature limit.
The fast flash conditions are used to protect the
video device from high temperature conditions.
Once conditions return to normal the device will
reset and the green indicator will stop flashing.
During any of these fault conditions, the display will be
blank and the indicator will continue to flash as long as
the vehicle is in R (Reverse) or until the conditions
return to normal.
Pressing and holding
zwhen the left indicator light is
flashing will turn off the video display along with the left
indicator light.

Universal Home Remote System
Operation (With Three Round LED)
This vehicle may have the Universal Home Remote
System. If there are three round Light Emitting Diode
(LED) indicator lights above the Universal Home
Remote buttons, follow the instructions below. This system provides a way to replace up to three
remote control transmitters used to activate devices
such as garage door openers, security systems, and
home automation devices.
Do not use this system 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.
Read the instructions completely before attempting to
program the transmitter. Because of the steps involved,
it may be helpful to have another person assist with
programming the transmitter.
Be sure to keep the original remote control transmitter
for use in other vehicles, as well as, for future
programming. Only the original remote control
transmitter is needed for Fixed Code programming. The
programmed buttons should be erased when the
vehicle is sold or the lease ends. See
“Erasing
Universal Home Remote Buttons” later in this section.
Park the vehicle outside of the garage when
programming a garage door. Be sure that people and
objects are clear of the garage door or gate that is
being programmed.

Exterior Lamps
The exterior lamps control
is located on the
instrument panel to the
left of the steering wheel.
It controls the following systems:
.Headlamps
.Taillamps
.Parking Lamps
.License Plate Lamps
.Instrument Panel Lights
The exterior lamps control has four positions:
O(Off): Turns off the automatic headlamps and
daytime running lamps (DRL). Turn the headlamp
control to the off position again to turn the automatic
headlamps or DRL back on.
For vehicles first sold in Canada, the off position will
only work when the vehicle is shifted into P (Park). AUTO (Automatic) :
Automatically turns on the
headlamps at normal brightness, together with the
following:
.Parking Lamps
.Instrument Panel Lights
.Taillamps
.License Plate Lamps
When the vehicle is turned off and the headlamps are in
AUTO, the headlamps may automatically remain on for
a set time. The time of the delay can be changed using
the DIC. See Driver Information Center (DIC)
on
page 4‑44(If Equipped).
; (Parking Lamps) : Turns on the parking lamps
together with the following:
.Instrument Panel Lights
.Taillamps
.License Plate Lamps
4-10

2(Headlamps) : Turns on the headlamps together with
the following:
.Parking Lamps
.Instrument Panel Lights
.Taillamps
.License Plate Lamps
When the headlamps are turned on while the vehicle is
on, the headlamps turn off automatically 10 minutes
after the ignition is turned off. When the headlamps are
turned on while the vehicle is off, the headlamps will
stay on for 10 minutes before automatically turning off
to prevent the battery from being drained. Turn the
headlamp control to off and then back to the headlamp
on position to make the headlamps stay on for an
additional 10 minutes.
Push the turn signal/multifunction lever toward the
instrument panel to change the headlamps from low
beam to high beam.
Headlamps on Reminder
A reminder chime will sound when the headlamps or
parking lamps are manually turned on and the ignition is
off, in LOCK/OFF, ACC/ACCESSORY, or a door is
open. Turn the light off, then back on, to stop the chime.
Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the day.
Fully functional daytime running lamps 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 lamps control is in AUTO.
.The engine is running.
.The light sensor determines it is daytime.
When the DRL system is on, only the DRL lamps are
on. The taillamps, sidemarker, 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 lamps, turn the exterior lamps
control to the OFF position and then release. For
vehicles first sold in Canada, the transmission must be
in the P (Park) position, before the DRL lamps can be
turned off.
4-11

Automatic Headlamp System
When it is dark enough outside, the automatic
headlamp system turns on the headlamps at the normal
brightness, along with the taillamps, sidemarker, parking
lamps, and the instrument panel lights. The radio lights
will also be dim.
To turn off the automatic headlamp system, turn the
exterior lamps switch to the off position and then
release it. For vehicles first sold in Canada, the
transmission must be in the P (Park) position, before the
automatic headlamp system can be turned off.
The vehicle has a light sensor located on the top of the
instrument panel in the defroster grille that regulates
when the automatic headlamps turn on. Do not cover
the sensor or the headlamps will come on whenever the
ignition is on.
The system may also turn on the headlamps when
driving through a parking garage, heavy overcast
weather, or a tunnel. This is normal.
There is a delay in the transition between the daytime
and nighttime operation of the Daytime Running Lamps
(DRL) and the automatic headlamp systems so that
driving under bridges or bright overhead street lightsdoes not affect the system. The DRL and automatic
headlamp system is only affected when the light sensor
detects a change in lighting lasting longer than the
delay.
If the vehicle is started in a dark garage, the automatic
headlamp system will come on immediately. Once the
vehicle leaves the garage, it takes approximately
one minute for the automatic headlamp system to
change to DRL if it is bright enough outside. During that
delay, the instrument panel cluster may not be as bright
as usual. Make sure the instrument panel brightness
control is in the full bright position. See
Instrument
Panel Brightness on page 4‑13.
To idle the vehicle with the automatic headlamp system
off, turn the control to the off position.
The headlamps will also stay on after you exit the
vehicle. This feature can be programmed using the
Driver Information Center (DIC). See DIC Vehicle
Customization (With DIC Buttons) on page 4‑67.
The regular headlamp system can be turned on when
needed.
