Automatic Headlamp
System
When it is dark enough outside,
the automatic headlamp system
will turn on after the transmission
has been shifted from P (Park) to
D (Drive). The headlamps, taillamps,
sidemarker, parking lamps, roof
marker lamps, and the instrument
panel lights turn on at normal
brightness. The radio lights will
become dimmer when the
headlights are off compared to
when the headlights are on.
The vehicle has a light sensor
located on the top of the instrument
panel. Do not cover the sensor,
or the system will be on whenever
the ignition is on.
The system can turn on the
headlamps when driving in a parking
garage, through a tunnel or when
there is overcast weather. 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 system so that driving
under bridges or bright overhead
street lights does not affect the
system. The DRL and automatic
headlamp system will only be
affected when the light sensor
detects a change in lighting lasting
longer than the delay.
If the vehicle is started in a dark
garage, the automatic headlamp
system will come on immediately.
Once the vehicle leaves 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, 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 3-15.
Off-Road Lamps
The off-road lamps, if the vehicle
has them, provide auxiliary lighting
when the vehicle is used off
road. These lamps are not intended
to be used in place of existing
vehicle lighting. The lamps are not
to be used on any public street
or highway and are to be covered
when not in use. Check your
state and local laws before installing
or using any auxiliary lighting. In
some states it may be necessary to
remove the roof lamps when
operating the vehicle on the
highway.

The air conditioning system removes
moisture from the air, so a small
amount of water might drip
under the vehicle while idling or
after turning off the engine. This is
normal.@(Recirculation):Press to turn
the recirculation mode on or off. An
indicator light comes on when the
recirculation is on. This mode
recirculates and helps to quickly cool
the air inside the vehicle. It can be
used to prevent outside air and odors
from entering the vehicle.
Recirculation is available in the
bi-level and vent modes. This mode
cannot be selected while in the oor,
oor/defog or defrost modes. If you
try to select the recirculation mode,
the indicator ashes three times
indicating it is not available in that
mode. When the recirculation mode
is turned on, the air conditioning
turns on automatically.
When it is hot enough outside, the
recirculation mode may turn on
automatically to help improve cooling
performance. The indicator light will
be lit to show this mode is active. If
the recirculation button is pressed
while in this mode, the light ashes
three times and stays on to indicate
that recirculation may not be shut off.

Bluetooth®
Vehicles with a Bluetooth system
can use a Bluetooth capable
cell phone with a Hands Free Prole
to make and receive phone calls.
The system can be used while
the key is in ON/RUN or
ACC/ACCESSORY position. The
range of the Bluetooth system
can be up to 30 ft. (9.1 m). Not all
phones support all functions,
and not all phones are guaranteed
to work with the in-vehicle
Bluetooth system. See
gm.com/bluetooth for more
information on compatible phones.
Voice Recognition
The Bluetooth system uses voice
recognition to interpret voice
commands to dial phone numbers
and name tags.Noise:Keep interior noise levels to
a minimum. The system may not
recognize voice commands if there
is too much background noise.
When to Speak:A short tone
sounds after the system responds
indicating when it is waiting for
a voice command. Wait until

Audio System
When using the in-vehicle Bluetooth
system, sound comes through
the vehicle’s front audio system
speakers and overrides the audio
system. Use the audio system
volume knob, during a call,
to change the volume level. The
adjusted volume level remains
in memory for later calls. To prevent
missed calls, a minimum volume
level is used if the volume is turned
down too low.

Instrument Panel 3-53

This device complies with RSS-210
of Industry Canada. Operation is
subject to the following two
conditions:
1. This device may not cause
interference.
2. This device must accept any
interference received, including
interference that may cause
undesired operation of the
device.
Changes or modications to this
system by other than an authorized
service facility could void
authorization to use this equipment.
Theft-Deterrent Feature
THEFTLOCK®is designed to
discourage theft of the vehicle’s radio
by learning a portion of the Vehicle
Identication Number (VIN). The
radio does not operate and LOCKED
displays if the radio is stolen or
moved to a different vehicle.When the when the ignition is in the
off position, a blinking red light on
the upper left side of the radio
indicates that THEFTLOCK
®
is armed.
Radio Reception
Frequency interference and static
can occur during normal radio
reception if items such as cell phone
chargers, vehicle convenience
accessories, and external electronic
devices are plugged into the
accessory power outlet. If there is
interference or static, unplug the item
from the accessory power outlet.
AM
The range for most AM stations is
greater than for FM, especially
at night. The longer range can cause
station frequencies to interfere
with each other. For better radio
reception, most AM radio stations
boost the power levels during
the day, and then reduce these
levels during the night. Static
can also occur when things likestorms and power lines interfere
with radio reception. When this
happens, try reducing the treble on
the radio.
FM Stereo
FM signals only reach about
10 to 40 miles (16 to 65 km).
Although the radio has a built-in
electronic circuit that automatically
works to reduce interference,
some static can occur, especially
around tall buildings or hills, causing
the sound to fade in and out.
XM™ Satellite Radio Service
XM Satellite Radio Service gives
digital radio reception from
coast-to-coast in the 48 contiguous
United States, and in Canada.
Just as with FM, tall buildings or hills
can interfere with satellite radio
signals, causing the sound to fade
in and out. In addition, traveling
or standing under heavy foliage,
bridges, garages, or tunnels
may cause loss of the XM signal for
a period of time.

Antilock Brake
System (ABS)
This vehicle has the Antilock Brake
System (ABS), an advanced
electronic braking system that will
help prevent a braking skid.
When the engine is started and the
vehicle begins to drive away,
ABS checks itself. A momentary
motor or clicking noise might
be heard while this test is going on.
This is normal.
If there is a problem with ABS, this
warning light stays on. See
Antilock Brake System (ABS)
Warning Light on page 3-28.Let us say the road is wet and you
are driving safely. Suddenly, an
animal jumps out in front of you. You
slam on the brakes and continue
braking. Here is what happens
with ABS:
A computer senses that the wheels
are slowing down. If one of the
wheels is about to stop rolling, the
computer will separately work
the brakes at each wheel.
ABS can change the brake pressure
to each wheel, as required, faster
than any driver could. This can help
the driver steer around the
obstacle while braking hard.
As the brakes are applied, the
computer keeps receiving updates
on wheel speed and controls braking
pressure accordingly.Remember: ABS does not change
the time needed to get a foot
up to the brake pedal or always
decrease stopping distance. If you
get too close to the vehicle in
front of you, there will not be enough
time to apply the brakes if that
vehicle suddenly slows or stops.
Always leave enough room up
ahead to stop, even with ABS.
Using ABS
Do not pump the brakes. Just hold
the brake pedal down rmly and
let antilock work. The brakes might
vibrate or some noise might be
heard, but this is normal.
