Compressor
The vehicle has an electric powered
air conditioning compressor. This
allows for continuous air
conditioning and/or high voltage
battery cooling operation, without
running the engine.
The compressor operating speed is
not tied to the engine speed, so
some noise may be heard from the
compressor, especially when air
conditioning use is high and the
engine has turned off. This is
normal.
Sensors
Solar Sensor
The solar sensor is on top of the
instrument panel, near the
windshield, where it monitors solar
intensity.The climate control system uses the
sensor information to adjust the
temperature, fan speed,
recirculation, and air delivery mode
for best comfort.
Do not cover the sensor; otherwise
the automatic climate control system
may not work properly.
Humidity Sensor
The humidity sensor is near the
base of the inside rearview mirror.
The climate control system uses the
sensor information to adjust the

{Warning
An underhood electric fan can
start up even when the engine is
not running and can cause injury.
Keep hands, clothing, and tools
away from any underhood
electric fan.
If the coolant inside the coolant
surge tank is boiling, do not do
anything else until it cools down.
The vehicle should be parked on a
level surface.
The coolant level should be up to
the cold fill line. If it is not, there
might be a leak at the radiator
hoses, heater hoses, radiator, water
pump, or somewhere else in the
cooling system.
{Warning
Do not touch heater or radiator
hoses, or other engine parts.
They can be very hot and can (Continued)
Warning (Continued)
burn you. Do not run the engine if
there is a leak; all coolant could
leak out. That could cause an
engine fire and can burn you. Fix
any leak before driving the
vehicle.
If there seems to be no leak, with
the engine on, check to see if the
cooling fans are running. If the
engine is overheating, the fans
should be running. If they are not,
the vehicle needs service. Turn off
the vehicle.
Engine Coolant
The engine cooling system in the
vehicle is filled with GM Premix
DEX-COOL engine coolant. See
Recommended Fluids and
Lubricants 0329. The coolant
requires changing at certain
intervals. See Maintenance
Schedule 0321. The following explains the cooling
system and how to check and add
coolant when it is low. If there is a
problem with engine overheating,
see
Engine Overheating 0252.
What to Use
{Warning
Plain water, or other liquids such
as alcohol, can boil before the
proper coolant mixture will. With
plain water or the wrong mixture,
the engine could get too hot but
there would not be an overheat
warning. The engine could catch
fire and you or others could be
burned.
Use GM Premix DEX-COOL engine
coolant. This mixture:
. Gives freezing protection down
to−37 °C (−34 °F), outside
temperature.
. Gives boiling protection up to
129 °C (265 °F), engine
temperature.
