headlamp GMC SIERRA 2007 Owner's Manual

Content Theft-Deterrent
Your vehicle may have a content theft-deterrent
alarm system.
To activate the theft-deterrent system, do the
following:
1. Open the door.
2. Lock the door with the Remote Keyless Entry
(RKE) transmitter. The security light should
come on and ash. The door does not need to
be open.
If the delayed locking feature is active, the
alarm will not be activated until all doors are
closed and the security light goes off.
3. Close all doors. The security light will stop
ashing and go off after approximately
30 seconds. The content theft deterrent alarm
is not armed until the security light goes off.If a door is opened without using the RKE
transmitter, a ten second pre-alarm will occur. The
horn will chirp and the lights will ash. If the key
is not placed in the ignition and turned to
START or the door is not unlocked by pressing
the unlock button on the RKE transmitter
during the ten second pre-alarm, the alarm will go
off. Your vehicle’s headlamps will ash and the
horn will sound for about two minutes, then
will turn off to save the battery power.
The theft-deterrent system will not activate if you
lock the doors with a key, the manual door lock, or
the power door lock switch. It activates only if you
use the RKE transmitter. You should also
remember that you can start your vehicle with the
correct ignition key if the alarm has been set off.
Here is how to avoid setting off the alarm
by accident:
If you do not want to activate the
theft-deterrent system, the vehicle should be
locked with the door key after the doors
are closed.
Always unlock a door with the RKE transmitter.
Unlocking a door any other way will set off the
alarm if the system has been armed.
128

If you set off the alarm by accident, turn off the
alarm by pressing unlock on the RKE transmitter or
by placing the key in the ignition and turning it
to START.
Testing the Alarm
The alarm can be tested by following these steps:
1. From inside the vehicle, lower the driver’s
window and open the driver’s door.
2. Activate the system by locking the doors with
the RKE transmitter.
3. Get out of the vehicle, close the door and wait
for the security light to go out.
4. Then reach in through the window, unlock the
door with the manual door lock and open the
door. This should set off the alarm.
If the alarm does not sound when it should, but
the vehicle’s headlamps ash, check to see if the
horn works. The horn fuse may be blown. To
replace the fuse, seeFuses and Circuit Breakers
on page 608.
If the alarm does not sound or the vehicle’s
headlamps do not ash, see your dealer for service.

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 “Resetting the Power Foldaway
Mirrors” next.
Resetting the Power Foldaway Mirrors

of the headlamps behind you. SeeAutomatic
Dimming Rearview Mirror with OnStar
®, Compass
and Temperature Display on page 169.
Curb View Assist
If your vehicle has the memory package, the
outside mirrors are able to perform the curb view
assist mirror function. This feature may be
useful in allowing the driver to view the curb when
parallel parking. 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).
The passenger’s and/or driver’s mirror will return
to its original position when the vehicle is
shifted out of REVERSE (R), or the ignition is
turned off or to LOCK.
This feature can be turned on or off through the
Driver Information Center (DIC). SeeDriver

Turn Signal On Chime
If your turn signal is left on for more than 3/4 of a
mile (1.2 km), a chime will sound at each ash
of the turn signal and the message TURN SIGNAL
ON will also appear in the Driver Information

toward you. Then release it.
When the high beams
are on, this indicator light
on the instrument panel
cluster will also be on.
Flash-to-Pass
This feature lets you use your high-beam
headlamps to signal a driver in front of you that
you want to pass. It works even if your headlamps
are in the automatic position.
To use it, pull the turn signal lever toward you,
then release it.
If your headlamps are in the automatic position or

Rainsense™ II Wipers
If your vehicle has Rainsense™ II windshield
wipers, the moisture sensor is located next to the
inside rearview mirror and is mounted on the
windshield. When active, these sensors are able
to detect moisture on the windshield and
automatically turn on the wipers.
To turn on the Rainsense™ feature, the wipers
must be set to one of the ve delay settings on the
multifunction lever. Each of the ve settings
adjusts the sensitivity of the rainsensor.
Since different drivers have different setting
preferences, it is recommended that the mid-range
setting (position 3) be used initially. For more
wipes, select the higher settings; for fewer wipes,
select the lower settings located closer to the
off position on the multifunction lever.The rainsensor will automatically control the
frequency of the wipes from the off setting to the
high speed setting according to the weather
conditions. The wipers can be left in a rainsense
mode even when it is not raining.
When Rainsense™ is active, the headlamps will
turn on automatically if the exterior lamp control is
in the AUTO position.
Notice:Going through an automatic car wash
with the wipers on can damage them. Turn
the wipers off when going through an
automatic car wash.

before automatically turning off to prevent the
battery from being drained. Turn the headlamp

the chime, turn the light off.
Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier
for others to see the front of your vehicle during
the day. DRL can be helpful in many different
driving conditions, but they can be especially
helpful in the short periods after dawn and before
sunset. Fully functional DRL are required on all
vehicles rst sold in Canada.
The DRL system will come on when the following
conditions are met:
The engine is running.
