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.
Airbags plus lap-shoulder belts offer protection for adults
and older children, but not for young children and infants.
Neither the vehicle’s safety belt system nor its airbag
system is designed for them. Every time infants and
young children ride in vehicles, they should have the
protection provided by appropriate child restraints.
Children who are not restrained properly can strike other
people, or can be thrown out of the vehicle.

Location information about the vehicle is only available
if the GPS satellite signals are unobstructed and
available.
The vehicle must have a working electrical system,
including adequate battery power, for the OnStar
equipment to operate. There are other problems OnStar

OnStar service at any particular time or place. Some
examples are damage to important parts of the vehicle
in a crash, hills, tall buildings, tunnels, weather or
wireless phone network congestion.

Automatic Headlamp System
When it is dark enough outside, the Automatic
Headlamp System turns on the headlamps when the
vehicle is started and after the transmission has been
shifted out of the P (Park) position. The headlamps,
taillamps, sidemarker, and parking lamps will come on.
The instrument panel lights and radio lights will also turn
on at normal brightness. Once on, the system remains on
during these conditions even if the vehicle is shifted back
into P (Park).
The vehicle has a light sensor on the top of the
instrument panel. Do not cover the sensor or the
system may come on whenever the ignition is on
and the vehicle is shifted out of the P (Park) position.
The system could also turn on the lamps 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 thatdriving under bridges or bright overhead street lights does
not affect the system. The DRL and automatic headlamp
system are only affected when the light sensor sees a
change in lighting lasting longer than the delay.
If the vehicle is started in a dark garage, the automatic
headlamp system comes on after the transmission
is shifted out of P (Park). Once the vehicle leaves the
garage, it takes about one minute for the automatic
headlamp system to change to DRL if it is light outside.
During that delay, the instrument panel cluster might
not be as bright as usual. Make sure the instrument
panel brightness control is in the full bright position.
If the vehicle is running and the automatic headlamp
system is already on, it can be turned off by turning
and releasing the headlamp control at the off position.
The automatic headlamp system stays off until you
turn and release the headlamp control at the off position
again. SeeHeadlamps on page 3-13.

#A/C (Air Conditioning):Press to turn the air
conditioning system on or off. When the system is on,
the system automatically begins to cool and dehumidify
the air inside of the vehicle. The air conditioning symbol
appears on the display when the air conditioning is on
and turns off when the air conditioning is off.
If the air conditioning is turned off while in front defrost
or defog mode, the air conditioning symbol turns off,
however, the A/C compressor remains on to help
de-humidify the air inside the vehicle. If one of the
other modes is selected, the compressor will then
turn the A/C off until it is selected again or the AUTO
button is pressed.
To avoid fogging the inside glass on rainy and humid
days at a temperature above freezing, press the air
conditioning button to run the A/C compressor. Also it is
best to avoid the use of the recirculation mode except
when maximum air conditioning performance is needed
or for short times to avoid exterior odors.
You may notice a slight change in engine performance
when the air-conditioning compressor shuts off and turns
on again. This is normal.@(Recirculation):Press to turn the recirculation
mode on or off. An indicator light comes on to show
that recirculation is on. This mode recirculates and
helps to quickly cool the air inside the vehicle. It can
be used to help prevent outside air and odors from
entering the vehicle. Recirculation mode can be used
with vent and bi-level modes, but it cannot be used
with oor, defog or defrost modes.
If recirculation mode is selected with oor, defog,
or defrost modes, the indicator ashes three times
and turns off to indicate the selection is not available.
The air conditioning compressor may also run while
in recirculation mode. This is normal and helps to
prevent window fogging.
If the weather is cold and damp, the system may cause
the windows to fog while using recirculation mode.
If the windows do start to fog, select defog or defrost
mode and increase fan speed.
Recirculation mode, if selected, will be cleared when the
engine is turned off.

Fuel Information Button
t
(Fuel Information):Press the fuel information
button to scroll through the range, fuel used, average
fuel economy, and the engine oil life system.
Fuel Range:Press the fuel information button until
RANGE appears on the display. This mode shows the
remaining distance you can drive without refueling.
It is based on fuel economy and the fuel remaining in
the fuel tank. The display will show LOW if the fuel level
is low.
The fuel economy data used to determine fuel range is
an average of recent driving conditions. As your
driving conditions change, this data is gradually updated.
Fuel range cannot be reset.
Fuel Used:Press the fuel information button until
FUEL USED appears on the display. This mode shows
the number of gallons or liters of fuel used since the
last reset of this menu item. To reset the fuel used
information, press and hold the select button for one
second while FUEL USED is displayed.Average Fuel Economy:Press the fuel information
button until AVG. ECON appears on the display.
This mode shows how many miles per gallon (MPG),
liters per 100 kilometers (L/100 km), or kilometers
per liter (km/L) your vehicle is getting based on current
and past driving conditions.
Press and hold the select button for one second while
AVG. ECON is displayed to reset the average fuel
economy. Average fuel economy will then be calculated
starting from that point. If the average fuel economy
is not reset, it will be continually updated each time you
drive.
Engine Oil Life System:Press the fuel information
button until ENGINE OIL LIFE appears on the display.
The engine oil life system shows an estimate of the
oil’s remaining useful life. It will show 100% when the
system is reset after an oil change. It will alert you
to change the oil on a schedule consistent with your
driving conditions.
Always reset the engine oil life system after an oil
change. To reset the engine oil life system, seeEngine
Oil Life System on page 5-22.
In addition to the engine oil life system monitoring the
oil life, additional maintenance is recommended in
the Maintenance Schedule in this manual. SeeEngine
Oil on page 5-18andScheduled Maintenance on
page 6-4.
