Radio Signals for Some Gate Operators
For questions or programming help, see
www.homelink.com/gm or call
1-800-355-3515. For calls placed outside the
U.S., Canada, or Puerto Rico, international
rates will apply and may differ based on
landline or mobile phone.
Some radio-frequency laws and gate
operators require transmitter signals to time
out or quit after several seconds of

5.
Driving with IntelliBeam
The system only activates the high beams
when driving over 40 km/h (25 mph).
The blue high-beam on light appears on the
instrument cluster when the high beams
are on.
There is a sensor near the top center of the
windshield that automatically controls the
system. Keep this area of the windshield
clear of debris to allow for best system
performance. The high-beam headlamps remain on, under
the automatic control, until one of the
following situations occurs:
.The system detects an approaching
vehicle's headlamps.
.The system detects a preceding vehicle's
taillamps.
.The outside light is bright enough that
high-beam headlamps are not required.
.The vehicle's speed drops below 20 km/h
(12 mph).
.The IntelliBeam system is disabled by the
button on the turn signal lever. If this
happens, press
bon the turn signal
lever when the exterior lamp control is in
the AUTO or
5position to reactivate the
IntelliBeam system. The instrument
cluster light will come on to indicate the
IntelliBeam system is reactivated.
The high beams may not turn off
automatically if the system cannot detect
another vehicle's lamps because of any of
the following:
.The other vehicle's lamps are missing,
damaged, obstructed from view,
or otherwise undetected.
.The other vehicle's lamps are covered
with dirt, snow, and/or road spray.
.The other vehicle's lamps cannot be
detected due to dense exhaust, smoke,
fog, snow, road spray, mist, or other
airborne obstructions.
.The vehicle's windshield is dirty, cracked,
or obstructed by something that blocks
the view of the light sensor.
.The vehicle is loaded such that the front
end points upward, causing the light
sensor to aim high and not detect
headlamps and taillamps.
.The vehicle is being driven on winding or
hilly roads.
The IntelliBeam system may need to be
disabled if any of the above conditions exist.

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.
The system may also turn on the headlamps
when driving through a parking garage or
tunnel. If the vehicle is started in a dark garage, the
automatic headlamp system comes on
immediately. If it is light outside when the
vehicle leaves the garage, there is a slight
delay before the automatic headlamp
system changes to the Daytime Running
Lamps (DRL). During that delay, the
instrument cluster may not be as bright as
usual. Make sure the instrument panel
brightness control is in the full bright
position. See
Instrument Panel Illumination

When it is bright enough outside, the
headlamps will turn off or may change
to DRL.

If the lever is moved momentarily to the
lane change position, the arrow will flash
three times. It will flash six times if Tow/
Haul Mode is active.
The lever returns to its starting position
when it is released.
If after signaling a turn or lane change, the
arrow flashes rapidly or does not come on, a
