press
bon the turn signal lever
when it is dark outside and the
exterior lamp control is in AUTO
or
2.
Driving with IntelliBeam
The system only activates the high
beams when driving over 40 km/h
(25 mph).
The blue high-beam on light appears
on the instrument cluster when the
high beams are on. 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, press
bon
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:
.The other vehicle's lamps are
missing, damaged, obstructed from
view, or otherwise undetected.
.The other vehicle's lamps are
covered with dirt, snow, and/or road
spray.
.The other vehicle's lamps cannot be
detected due to dense exhaust,
smoke, fog, snow, road spray, mist,
or other airborne obstructions.
.The vehicle's windshield is dirty,
cracked, or obstructed by something
that blocks the view of the light
sensor.
.The vehicle is loaded such that the
front end points upward, causing
the light sensor to aim high and not
detect headlamps and taillamps.
.The vehicle is being driven on
winding or hilly roads.
The automatic high-beam headlamps
may need to be disabled if any of the
above conditions exist.

The Nav application requires a map
database to run. It is stored on an SD
card that is connected to the
infotainment system. If the map
database is not available, a missing SD
card error message will be displayed.
SD Card Error Messages
The SD card only works for one
unique vehicle. The SD card must pass
authentication verification to be used for that specific vehicle. Do not
remove SD card while the ignition
is on.
Potential error scenarios and
messages include:
.The SD card has initialized for the
first time:
“Once initialized, this SD
card can only be used for navigation
in this vehicle.” Make sure the SD
card switch is in an upward
position.
.The SD card is not working
properly: “SD card is not functioning
properly. (Error Code).”
.The SD card is not paired with the
existing system: “This Nav SD card
is not valid in this vehicle for
navigation. See Owner’s Manual for
more detail or visit your dealer.
(Error Code).”
.The SD card has been removed from
the slot: “SD card has been removed.

signals, various vehicle signals, and
map data.
At times, other interference such as
the satellite condition, road
configuration, condition of the vehicle,
and/or other circumstances can affect
the navigation system's ability to
determine the accurate position of the
vehicle.
The GPS shows the current position of
the vehicle using signals sent by GPS
satellites. When the vehicle is not
receiving signals from the satellites, a
symbol appears in the status bar.
This system might not be available or
interference can occur if any of the
following are true:
.Signals are obstructed by tall
buildings, trees, large trucks, or a
tunnel.
.Satellites are being repaired or
improved.

Climate Control Influence on
Fuel Economy
The climate control system depends
on other vehicle systems for heat and
power input. Certain climate control
settings can lead to higher fuel usage.
The following climate control settings
use more fuel:
.MAX air conditioning mode
.Defrost mode
.Extreme temperature settings, such
as 15° C (60° F) or 32° C (90° F)
.High fan speed settings
To help reduce fuel usage:
.Use the full automatic control as
described under “Automatic
Operation.”
.Select a temperature setting that is
higher in hot weather and lower in
cold weather.
.Turn off the air conditioning when
it is not needed.
.Only use defrost to clear the
windows.

ventilated seats will turn on if it is hot
outside. The heated and ventilated
seat indicator lights may not come on
during a remote start. If equipped, the
heated steering wheel will come on in

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 0120.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.
Afterblow Feature
If equipped, under certain conditions,
the fan may stay on or may turn on
and off several times after you turn
off and lock the vehicle. This is
normal.

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 airf low 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 Schedule0408.
See your dealer regarding replacement
of the filter.
Service
All vehicles have a label underhood
that identifies the refrigerant used in
the vehicle. The refrigerant system
should only be serviced by trained and
certified technicians. The air
conditioning evaporator should never
be repaired or replaced by one from a
salvage vehicle. It should only be
replaced by a new evaporator to
ensure proper and safe operation.
During service, all refrigerants should
be reclaimed with proper equipment.
Venting refrigerants directly to the
atmosphere is harmful to the
environment and may also create
unsafe conditions based on inhalation,
combustion, frostbite, or other
health-based concerns.
The air conditioning system requires
periodic maintenance. See
Maintenance Schedule 0408.
