Messages
A/C OFF DUE TO HIGH
ENGINE TEMP
This message displays when the
engine coolant becomes hotter than
the normal operating temperature.
To avoid added strain on a hot
engine, the air conditioning
compressor automatically turns off.

driven.
If this message continues to appear,
have the system repaired by your
dealer as soon as possible to avoid
damage to the engine.
COOLANT LEVEL LOW ADD
COOLANT
This message will display if the
coolant is low. SeeEngine Coolant
on page 10-16.
ENGINE OVERHEATED —
IDLE ENGINE
This message displays when the
engine coolant temperature is too
hot. Stop and allow the vehicle to
idle until it cools down.
ENGINE OVERHEATED —
STOP ENGINE
This message displays and a
continuous chime sounds if the
engine cooling system reaches
unsafe temperatures for operation.
Stop and turn off the vehicle as
soon as it is safe to do so to avoid
severe damage. This message
clears when the engine has cooled

8-4 Climate Controls
Air Delivery Mode Control:When
the climate information is displayed,
press the desired air delivery mode
on the touch screen to change the
direction of the airflow. The selected
air delivery mode button is lit.
Pressing any of the air delivery
buttons cancels automatic air
delivery control and the direction of
the airflow can be controlled
manually. Press AUTO to return to
automatic operation.
To change the current mode, select
one of the following:
Y(Vent): Air is directed to the
instrument panel outlets.
\(Bi-Level): Air is divided
between the instrument panel
outlets and the floor outlets.
[(Floor): Air is directed to the
floor outlets.
-(Defog): Clears the windows of
fog or moisture. Air is directed to the
windshield and floor outlets.
0(Defrost): Clears the
windshield of fog or frost more
quickly. Air is directed to the
windshield. Press the
0button to
turn on or off. Changing the air
delivery mode also turns the
defrost off.
#(Air Conditioning): Press the
AC Mode touch screen control to
turn the automatic air conditioning
on or off. If the fan is turned off or
the outside temperature falls below
freezing, the air conditioner will
not run.
Press AUTO to return to automatic
operation and the air conditioner
runs as needed.
Automatic Air Recirculation:
When the AUTO indicator light is
on, the air is automatically
recirculated as needed to help
quickly cool the inside of the
vehicle.
The climate control system may
have a sensor to detect air pollution.
When using automatic air recirculation, the air quality control
system may operate. To adjust the
sensitivity of the air quality sensor,
see
“Climate and Air Quality” under
Vehicle Personalization on
page 5-48.
@(Recirculation): Press to
alternate between recirculating air
inside the vehicle or pulling in
outside air. The indicator light on the
button is lit when recirculation mode
is active. This helps to quickly cool
the air inside the vehicle or prevent
outside air and odors from entering.
Pressing this button cancels
automatic recirculation. Press AUTO
to return to automatic operation;
recirculation runs automatically as
needed.
Manual recirculation mode is not
available when in Defrost or Defog
modes.
Auto Defog: The climate control
system may have a sensor to
automatically detect high humidity
inside the vehicle. When high
humidity is detected, the climate

.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 removes 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.
SeeMaintenance Schedule on
page 11-4.
See your dealer regarding
replacement of the filter.
Service
This vehicle may have the new
environmentally friendly refrigerant,
R1234yf. This refrigerant has a
significantly reduced global warming
impact on the environment,
compared to the traditional
automotive refrigerant, R-134a. 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.

10-20 Vehicle Care
Warning (Continued)
Wait until there is no sign of
steam or coolant before you open
the hood.
If you keep driving when the
engine is overheated, the liquids
in it can catch fire. You or others
could be badly burned. Stop the
engine if it overheats, and get out
of the vehicle until the engine
is cool.
If No Steam Is Coming from
the Engine Compartment
If an engine overheat warning is
displayed but no steam can be seen
or heard, the problem may not be
too serious. Sometimes the engine
can get a little too hot when the
vehicle:
.Climbs a long hill on a hot day.
.Stops after high-speed driving.
.Idles for long periods in traffic.
.Tows a trailer.
If the overheat warning is displayed
with no sign of steam:
1. Turn the air conditioning off.
2. Turn the heater on to the highest temperature and to the highest
fan speed. Open the windows as
necessary.
3. When it is safe to do so, pull off the road, shift to P (Park) or
N (Neutral), and let the
engine idle.
If the temperature overheat gauge is
no longer in the overheat zone or an
overheat warning no longer
displays, the vehicle can be driven.
Continue to drive the vehicle slow
for about 10 minutes. Keep a safe
vehicle distance from the car in front
of you. If the warning does not come
back on, continue to drive normally
and have the cooling system
checked for proper fill and function. If the warning continues, pull over,
stop, and park the vehicle
right away.
If there is no sign of steam, idle the
engine for three minutes while
parked. If the warning is still
displayed, turn off the engine until it
cools down. Also, see
“Overheated
Engine Protection Operating Mode”
next in this section.
Overheated Engine
Protection
Operating Mode
This emergency operating mode
allows the vehicle to be driven to a
safe place in an emergency
situation. If an overheated engine
condition exists, an overheat
protection mode, which alternates
firing groups of cylinders, helps
prevent engine damage. In this
mode, there is significant loss in
power and engine performance.
