Infants and Young Children
Everyone in a vehicle needs protection! This includes
infants and all other children. Neither the distance
traveled nor the age and size of the traveler changes
the need, for everyone, to use safety restraints. In fact,
the law in every state in the United States and in
every Canadian province says children up to some
age must be restrained while in a vehicle.{CAUTION:
Children can be seriously injured or strangled
if a shoulder belt is wrapped around their
neck and the safety belt continues to tighten.
Never leave children unattended in a vehicle
and never allow children to play with the
safety belts.
Every time infants and young children ride in vehicles,
they should have the protection provided by appropriate
restraints. Children who are not restrained properly can
strike other people, or can be thrown out of the vehicle.
In addition, young children should not use the vehicle’s
adult safety belts alone; they need to use a child restraint.

Mirrors
Automatic Dimming Rearview Mirror
with OnStar
®and Compass
The vehicle may have an automatic dimming rearview
mirror with OnStar®, a compass and map lamps.
Three OnStar®buttons are at the bottom of the mirror.
SeeOnStar®System on page 2-43for more
information on the services OnStar®provides.
Mirror Operation
The mirror automatically changes to reduce glare from
headlamps behind you. A time delay feature prevents
rapid changing from the day to night positions while
driving under lights and through traffic.
P(On/Off):The automatic dimming feature is
activated when the vehicle is started. The automatic
dimming feature is turned on or off by pressing
this button located on the lower part of the mirror. Press
and hold the button for up to three seconds to turn
this feature on or off.
T(Indicator Light):This light will turn on when the
automatic dimming feature is active.
Map Lamps
The mirror has map lamps located at the bottom of the
mirror. To manually turn the lamps on or off, press
the button next to each lamp.
Compass Operation
The mirror has an eight-point compass display in the
bottom of the mirror face.
When the ignition and the compass feature are on,
the compass will show two character boxes for
approximately two seconds. After two seconds, the
mirror will display the current compass heading.
For example, NE is displayed for north-east.
Compass Calibration
If after two seconds the display does not show a
compass heading, there may be a strong magnetic eld
interfering with the compass. Such interference may
be caused by a magnetic antenna mount, note
pad holder or similar object. If the letter C appears in
the compass window, the compass needs calibration.
The mirror compass can be calibrated by driving
the vehicle in circles at 5 mph (8 km/h) or less until the
display reads a direction.
The compass can be placed in calibration mode by
pressing and holding the left map light button until
a C appears on the compass display.

Cleaning the Mirror
When cleaning the mirror, use a paper towel or similar
material dampened with glass cleaner. Do not spray
glass cleaner directly on the mirror as that may cause
the liquid cleaner to enter the mirror housing.
Automatic Dimming Rearview Mirror
with Compass
If the vehicle has this feature, an automatic dimming
mirror automatically dims to the proper level to minimize
glare at night from lights behind your vehicle.
The mirror also includes a compass display in the upper
right corner of the mirror face.
P(On/Off):This is the on/off button.
Automatic Dimming Mirror Operation
The automatic dimming mirror function is turned on each
time the ignition is started. A light near the on/off button
will come on to indicate the automatic dimming is on.
Press the on/off button for about six seconds to
manually turn the automatic dimming function on or off.
Compass Display
Press the on/off button, located to the far left, briey to
turn the compass display on or off.
If the display reads CAL, the compass needs to be
calibrated. For more information, see “Compass
Calibration” later in this section.
To adjust between Fahrenheit and Celsius:
1. Press and hold the on/off button for approximately
four seconds until either a ashing °F, or °C
appears.
2. Press the button again to change the display to the
desired unit of measurement. After approximately
four seconds of inactivity, the new unit will be locked
in and the compass/temperature display will return.
If an abnormal temperature reading is displayed
for an extended period of time, please consult your
dealer/retailer. Under certain circumstances, a delay in
updating the temperature is normal.

Turn and Lane-Change Signals
(Auto Signal)
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 multifunction lever all the
way up or down. When the turn is nished, the lever will
return automatically.
An arrow on the instrument
panel cluster will ash in
the direction of the
turn or lane change.
To signal a lane change, just raise or lower the lever
until the arrow starts to ash. Release the lever and the
turn signal will automatically ash three times. If more
ashes are desired, continue to hold the lever.
If you signal a turn or a lane change and the arrows ash
faster than normal, a signal bulb may be burned out.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 the fuses and check for burned-out
bulbs. SeeFuses and Circuit Breakers on page 5-100.
Turn Signal on Chime
A chime will remind you if you leave the turn signal on
for more than three-quarters of a mile (1.2 km) of
driving.
If you need to leave the turn signal on for more than
three-quarters of a mile (1.2 km), turn off the signal and
then turn it back on.
Headlamp High/Low-Beam Changer
To change the headlamps from low beam to high,
push the turn signal lever all the way forward. To change
from high to low beam, pull the lever rearward.
While the high beams are
on, this light on the
instrument panel cluster
will also be lit.
3-9

When it is dark enough outside, the front turn signal
lamps turn off and the normal low-beam headlamps
turn on.
When it is bright enough outside, the regular lamps
go off, and the front turn signal lamps will take over.
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 light outside. During that delay,
the instrument panel cluster may not be as bright
as usual. Make sure the instrument panel brightness
knob is in the full bright position. SeeInstrument Panel
Brightness on page 3-19for more information.
If it is dark enough outside and the exterior lamp control
is off, a HEADLAMPS SUGGESTED message will
display on the Driver’s Information Center (DIC).
SeeDIC Warnings and Messages on page 3-57.
Turning the exterior lamp control to off a second time,
or turning on the headlamps will remove the
HEADLAMPS SUGGESTED message in the DIC.
If the parking lamps or the fog lamps were turned on
instead, the HEADLAMPS SUGGESTED message
will continue to be displayed.
The regular headlamp system should be turned on
when needed.To turn off the DRL, turn the exterior lamp control to
the off position or shift into PARK (P). The DRL
will stay off until the control is toggled again or the
vehicle is shifted out of PARK (P).
This procedure applies only to vehicles rst sold in the
United States.
Fog Lamps
Use fog lamps for better vision in foggy or misty
conditions.
The fog lamps control is located on the multifunction
lever next to the exterior lamp control.
-(Fog Lamps):Turning the band to this position will
turn the fog lamps on.
When you turn the fog lamps on, the fog lamp light will
appear on the instrument panel cluster to indicate
that the fog lamps and the parking lamps are on.
If you turn the high-beam headlamps on, the fog lamps
will turn off. They will turn on again when you switch
to low-beam headlamps.
The ignition must be on for the fog lamps to operate.
Some localities have laws that require the headlamps to
be on along with the fog lamps.
3-17

Twilight Sentinel®
Twilight Sentinel®can turn your lamps on and off for you.
A light sensor on top of the instrument panel makes the
Twilight Sentinel
®work, so be sure it is not covered.
With Twilight Sentinel
®, you will see the following
happen:
When it is dark enough outside, the front turn signal
lamps (DRL) will go off, and the headlamps and
parking lamps will come on. The other lamps
that come on with headlamps will also come on.
When it is bright enough outside, the headlamps
will go off, and the front turn signal lamps (DRL)
will come on, as long as the exterior lamp switch is
in the AUTO position.
If you start your vehicle in a dark garage, the automatic
headlamp system will come on immediately. Once you
leave the garage, it will take about one minute for the
automatic headlamp system to change to DRL if it is light
outside. During that delay, your instrument panel cluster
may not be as bright as usual. Make sure your instrument
panel brightness control is in full bright position.
SeeInstrument Panel Brightness on page 3-19.You can idle the vehicle with the lamps off, even when
it is dark outside.
After starting the vehicle, turn the exterior lamp control
band on the multifunction lever to off and then
release it. The lamps will remain off until you turn the
control band to off again.
Twilight Sentinel
®also provides exterior illumination as
you leave the vehicle. If Twilight Sentinel®has turned
on the lamps when you turn off the ignition, your lamps
will remain on until:
The exterior lamp switch is moved from off to the
parking lamp position, or
A delay time that you select has elapsed.
See “Personal Options” underDIC Vehicle
Personalization on page 3-75to select the delay time
that you want. You can also select no delay time.
If you turn off the ignition with the exterior lamp switch
in the parking lamp or headlamp position, the Twilight
Sentinel
®delay will not occur. The lamps will turn off as
soon as the switch is turned off.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
