Head-Up Display (HUD)
{Warning
If the HUD image is too bright or
too high in your field of view, it
may take you more time to see
things you need to see when it is
dark outside. Be sure to keep the
HUD image dim and placed low in
your field of view.
If equipped with HUD, some
information concerning the operation
of the vehicle is projected onto the windshield. The information is
projected through the HUD lens on
the driver side of the instrument
panel and focused out toward the
front of the vehicle.
Caution
If you try to use the HUD image as
a parking aid, you may misjudge
the distance and damage your
vehicle. Do not use the HUD image
as a parking aid.
The HUD information can be
displayed in various languages. The
speedometer reading and other
numerical values can be displayed in
either English or metric units.
The language selection is changed
through the radio and the units of
measurement is changed through the
instrument cluster. See “Settings”in
the Infotainment Manual and
"Options" under Instrument Cluster
0 93.

IntelliBeam System
If equipped, this system turns the
vehicle's high-beam headlamps on and
off according to surrounding traffic
conditions.
The system turns the high-beam
headlamps on when it is dark enough
and there is no other traffic present.
This light
bcomes on in the

The blue high-beam on light appears
on the instrument cluster when the
high beams are on.
Driving with IntelliBeam
The system only activates the high
beams when driving over 40 km/h
(25 mph).
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, pressb
on the turn signal lever when the
exterior lamp control is in the
AUTO or
2position 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:

Automatic Headlamp
System
When the exterior lamp control is set
to AUTO and it is dark enough
outside, the headlamps come on
automatically.
The light sensor is on top of the
instrument panel or on the windshield
near the rearview mirror. Do not cover
the sensor, otherwise the headlamps
will come on when they are not
needed.
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 turns off the headlamps.
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 Control 0129.
When it is bright enough outside, the
headlamps will turn off.
The automatic headlamp system turns

change is completed. If the lever is
briefly pressed and released, the turn
signal flashes three times.
The turn and lane-change signal can
be turned off manually by moving the
lever back to its original position.If after signaling a turn or lane
change, the arrow flashes rapidly or
does not come on, a signal function
may be inoperative. This vehicle may

The system automatically controls the
following four functions to heat or
cool the vehicle to the desired
temperature:
.Fan Speed
. Air Delivery Mode
. Air Conditioning
. Recirculation
When the AUTO indicator light is lit,
all four functions are operating
automatically. Each function can be
manually set and the selected setting
will be shown. This cancels full

heated steering wheel indicator light
may not come on.
Ionizer :If equipped with an ionizer,
this feature helps to clean the air
inside the vehicle and remove
contaminants such as pollen, odors,
and dust. If the climate control
system is on and the ionizer is
enabled, the ionizer status indicator
will be lit on the climate control
display. To turn the ionizer on or off,
see Climate and Air Quality under
Vehicle Personalization 0116.Sensors
The solar sensor, located in the
defrost grille in the middle of the
instrument panel, monitors the solar
heat. Do not cover the solar sensor or
the system will not work properly.
There is also an exterior temperature
sensor behind the front grille. This
sensor reads the outside air
temperature and helps maintain the
temperature inside the vehicle. Any
cover on the front of the vehicle,
could cause a false reading in the
displayed temperature. The climate control system uses the
information from these sensors to
maintain comfort settings by
adjusting the outlet temperature, fan
speed, and air delivery mode. The
system may also supply cooler air to
the side of the vehicle facing the sun.
The recirculation mode will also be
used as needed to maintain cool
outlet temperatures.

Air Vents
Adjustable air vents are in the center
and on the sides of the instrument
panel, and on the rear of the center
console storage.
Move the slider knobs to change the
direction of or to close off the airf low.Operation Tips
.
Clear away any ice, snow, or leaves
from air inlets at the base of the
windshield that could block the
flow of air into the vehicle.
. Clear snow off the hood to
improve visibility and help
decrease moisture drawn into the
vehicle.
. Keep the path under the front
seats clear of objects to help
circulate the air inside of the
vehicle more effectively.
. Use of non-GM approved hood
deflectors can adversely affect the
performance of the system. Check
with your dealer before adding
equipment to the outside of the
vehicle.
. Do not attach any devices to the
air vent slats. This restricts airflow
and may cause damage to the air
vents.
Maintenance
Passenger Compartment
Air Filter
The filter reduces dust, pollen, and
other airborne irritants from outside
air that is pulled into the vehicle. The
filter should be replaced as part of
routine scheduled maintenance. See
Maintenance Schedule 0303.
See your dealer regarding replacement
of the filter.

DRIVING AND OPERATING 153
{Warning
Snow can trap engine exhaust
under the vehicle. This may cause
exhaust gases to get inside. Engine
exhaust contains carbon monoxide
(CO), which cannot be seen or
smelled. It can cause
unconsciousness and even death.
If the vehicle is stuck in snow:. Clear snow from the base of
the vehicle, especially any
blocking the exhaust pipe.
. Open a window about 5 cm
(2 in) on the vehicle side that
is away from the wind, to
bring in fresh air.
. Fully open the air outlets on
or under the instrument
panel.
. Adjust the climate control
system to circulate the air
inside the vehicle and set the

Warning (Continued)
fan speed to the highest
setting. See“Climate Control
Systems.”
For more information about CO, see
Engine Exhaust 0168.
To save fuel, run the engine for short
periods to warm the vehicle and then
shut the engine off and partially close
the window. Moving about to keep
warm also helps.
If it takes time for help to arrive,
when running the engine, push the
accelerator pedal slightly so the
engine runs faster than the idle speed.
This keeps the battery charged to
restart the vehicle and to signal for
help with the headlamps. Do this as
little as possible, to save fuel.
If the Vehicle Is Stuck
Slowly and cautiously spin the wheels
to free the vehicle when stuck in sand,
mud, ice, or snow. If stuck too severely for the traction
system to free the vehicle, turn the
traction system off and use the
rocking method. See
Traction Control/
Electronic Stability Control 0182.
{Warning
If the vehicle's tires spin at high
speed, they can explode, and you or
others could be injured. The vehicle
can overheat, causing an engine
compartment fire or other damage.
Spin the wheels as little as possible
and avoid going above 56 km/h
(35 mph).
Rocking the Vehicle to Get it Out
Turn the steering wheel left and right
to clear the area around the front
wheels. Turn off any traction system.
Shift back and forth between
R (Reverse) and a low forward gear,
spinning the wheels as little as
possible. To prevent transmission
wear, wait until the wheels stop
spinning before shifting gears. Release
the accelerator pedal while shifting,
and press lightly on the accelerator
