Restart the vehicle and have the person remain in
this position for two to three minutes. This will allow
the system to detect that person and then enable
the right front passenger’s frontal airbag.
Safety belts help keep the passenger in position
on the seat during vehicle maneuvers and braking,
which helps the passenger sensing system maintain
the passenger airbag status. See “Safety Belts” and
“Child Restraints” in the Index for additional information
about the importance of proper restraint use.
{CAUTION:
If the airbag readiness light in the instrument
panel cluster ever comes on and stays on,
it means that something may be wrong with
the airbag system. If this ever happens, have
the vehicle serviced promptly, because an
adult-size person sitting in the right front
passenger’s seat may not have the protection
of the airbag(s). SeeAirbag Readiness Light
on page 3-27for more on this, including
important safety information.

Turn and Lane-Change Signals
The turn signal has two upward (for right) and
two downward (for left) positions. These positions
allow you to signal a turn or a lane change.
To signal a turn, move the lever all the way up or
down. When the turn is finished, the lever will return
automatically.
An arrow on the instrument
panel cluster will flash
in the direction of the
turn or lane change.
To signal a lane change, raise or lower the lever until
the arrow starts to flash. The turn signals automatically
flash three times and if the tow-haul mode is active
it flashes six times. Holding the turn signal lever for
more than one second causes the turn signals to
flash continually until the lever is released. The lever
returns by itself when you release it.An arrow on the instrument panel cluster flashes in the
direction of the turn or lane change.
If arrows flash more quickly than normal when a turn or
lane change is signaled, a signal bulb may be burned
out and other drivers may not see your turn signal.
If a bulb is burned out, replace it to help avoid an
accident. If the arrows do not go on at all when you
signal a turn, check for burned-out bulbs or a blown
fuse. SeeFuses and Circuit Breakers on page 5-104.
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 flash of the turn
signal and the message TURN SIGNAL ON also appears
in the Driver Information Center (DIC). SeeDIC Warnings
and Messages on page 3-49. To turn off the chime and
message, move the turn signal lever to the off position.
3-8 

Headlamp High/Low-Beam Changer
23(Headlamp High/Low-Beam Changer):
To change the headlamps from low to high beam,
pull the multifunction lever all the way toward you.
Then release it.
When the high beams
are on, this light on the
instrument panel cluster
also will be on.
Flash-to-Pass
This feature allows you to 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 off.
To use it, pull the turn signal lever toward you, but not so
far that you hear it click.
If your headlamps are off or on low-beam, your
high-beam headlamps will turn on and stay on as long
as you hold the lever toward you and the high-beam
indicator on the instrument panel will come on. Release
the lever to turn the high-beam headlamps off.
Windshield Wipers
The windshield wipers are controlled by turning the
band with the wiper symbol.
8(Mist):For a single wiping cycle, turn the band to
mist. Hold it there until the wipers start, then let go.
The wipers will stop after one wipe. If more wipes
are needed, hold the band on mist longer.
6Delay:The wiper speed can be set for a long or short
delay between wipes. This can be very useful in light rain
or snow. Turn the band to choose the delay time. The
closer to the top of the lever, the shorter the delay.
d(Low Speed):For steady wiping at low speed,
turn the band away from you to the first solid band past
the delay settings position.
a(High Speed):For high-speed wiping, turn
the band further, to the second solid band past the
delay settings.
9(Off):To stop the wipers, move the band to off.
When driving during the day and the wipers are
activated, the head lamps will automatically turn on
after completing eight wipe cycles.
Be sure to clear ice and snow from the wiper blades
before using them. If they are frozen to the windshield,
carefully loosen or thaw them. If your blades do become
worn or damaged, get new blades or blade inserts.

SeeStabiliTrak®System on page 4-5. When road
conditions allow you to safely use it again, you may turn
the cruise control back on.
The cruise control buttons
are located on left side of
the steering wheel.
T(On/Off):This button can both activate and turn
off the system. The indicator light on the button turns on
when cruise control is on and turns off when cruise
control is off.
+ RES (Resume/Accelerate):Press this button to
make the vehicle accelerate or resume to a previously
set speed.
SET−(Set/Coast):Press this button to set the speed
or make the vehicle decelerate.
[(Cancel):Press this button to cancel cruise control
without erasing the set speed from memory.
Setting Cruise Control
Cruise control will not work if your parking brake is set,
or if the master cylinder brake fluid level is low.
The cruise control light on the instrument panel cluster
will come on after the cruise control has been set to
the desired speed.
{CAUTION:
If you leave your cruise control on when you
are not using cruise, you might hit a button
and go into cruise when you do not want to.
You could be startled and even lose control.
Keep the cruise control switch off until you
want to use cruise control.
1. Press the cruise control On/Off button.
2. Get up to the desired speed.
3. Press the SET−button located on the steering
wheel and release it.
4. Take your foot off the accelerator.

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
30 seconds for the automatic headlamp system to
change to DRL if it is light 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. SeeInstrument Panel Brightness
on page 3-16.
Instrument Panel Brightness
The knob for this feature is located next to the exterior
lamps control.
D(Instrument Panel Lights):Turn the knob
clockwise or counterclockwise to brighten or dim the
instrument panel lights and the radio display. This only
works if the headlamps or parking lamps are on.
To turn on the dome lamps, with the vehicle doors
closed, turn the knob all the way clockwise.
Dome Lamps
The dome lamps come on when any door is opened.
They turn off after all the doors are closed.
The dome lamps can also be turned on by turning the
instrument panel brightness knob, located next to
the exterior lamps control, clockwise to the farthest
position. In this position, the dome lamps remain
on whether a door is opened or closed.
Dome Lamp Override
The dome lamp override button is located next to the
exterior lamps control.
The dome lamp override is used to set the dome lamps
to remain off or come on automatically when a door
is opened.
E(Dome Lamp Override):Press the button in and
the dome lamps remain off when a door is opened.
Press the button again to return it to the extended
position so that the dome lamps come on when a
door is opened.

Instrument Panel Cluster
The instrument panel cluster is designed to let you know at a glance how the vehicle is running. You will know how
fast you are going, how much fuel you are using, and many other things you will need to know to drive safely and
economically. If your vehicle has the DURAMAX
®Diesel engine, see the DURAMAX®Diesel manual for more
information.
