Engine Cooling System
Messages
Engine Hot A/C (Air
Conditioning) Off
This message displays when the
engine coolant becomes hotter than
the normal operating temperature.
SeeEngine Coolant Temperature
Gauge
on page 5‑16. To avoid
added strain on a hot engine, the air
conditioning compressor
automatically turns off. When the

normal, the air conditioning
compressor turns back on. You can
continue to drive the vehicle.
If this message continues to appear,
have the system repaired by your
dealer as soon as possible to avoid
damage to the engine.
Engine Overheated Idle Engine
Notice: If you drive your vehicle
while the engine is overheating,
severe engine damage may
occur. If an overheat warning

engine coolant temperature is too
hot. Stop and allow the vehicle to
idle until it cools down. If the
message does not clear in a
few minutes or if the overheat light
stays on, shut the vehicle off and
have it serviced before driving
again. See Engine Coolant

Electronic Key Not Detected
If the vehicle has the keyless
access system, this message
displays if the vehicle does not
detect the presence of a transmitter
when you have attempted to start
the vehicle or a vehicle door has
just closed. The following conditions
may cause this message to appear:
.Driver-added equipment plugged
into the accessory power outlet
on the center console is causing
interference. Examples of these
devices are cell phones and cell
phone chargers, two-way radios, power inverters, or similar items.
Try moving the keyless access
transmitter away from these
devices when starting the
vehicle. In addition, PDA devices
and remote garage and gate
openers may also generate
Electromagnetic Interference
(EMI) that may interfere with the
keyless access transmitter. Do
not carry the keyless access
transmitter in the same pocket or
bag as these devices.
.The vehicle is experiencing
Electromagnetic Interference
(EMI). Some locations, such as
airports, automatic toll booths,
and some gas stations have EMI
fields which may interfere with
the keyless access transmitter.
If moving the transmitter to
different locations within the
vehicle does not help, place the
transmitter in the center console
transmitter pocket with the
buttons facing the front of the
vehicle and then start the
vehicle.
.The vehicle's battery voltage is
low. The battery voltage must be
above 10 volts for the keyless
access transmitter to be
detected properly.

8-2 Climate Controls
Automatic Operation
AUTO (Automatic):The system
automatically controls fan speed, air
delivery, and air conditioning in
order to heat or cool the vehicle to
the desired temperature. When the
indicator light is on, the system is in
full automatic operation. If the air
delivery mode or fan setting is
manually adjusted, the auto
indicator turns off and displays will
show the selected settings.
1. Press the AUTO button.
2. Adjust the temperature to a comfortable setting between
21°C (70°F) and 27°C (80°F).
Choosing the coldest or warmest
temperature setting will not
cause the system to heat or cool
any faster.
To avoid blowing cold air in cold
weather, the system delays
turning on the fan until warm air
is available. The system starts
out blowing air at the floor, but
can automatically change modes as the vehicle warms up to
maintain the chosen temperature
setting. The length of time
needed for warm up depends on
the outside temperature and the
length of time that has elapsed
since the vehicle was last driven.
3. Wait for the system to regulate. This may take from 10 to
30 minutes. Then adjust the
temperature, if necessary.
English can be changed to metric
units through the Driver Information
Center (DIC). See Driver
Information Center (DIC)
on
page 5‑27.
Q/R(Temperature Control):
The temperature can be adjusted
separately for the driver and the
passenger. Press to increase or
decrease the automatic temperature
settings.
PASS (Passenger Climate
Control): Press to set a different
temperature for the passenger. Then adjust the passenger
temperature buttons to a
comfortable setting.
Pressing the PASS button again
automatically sets the passenger's
temperature to the driver's setting.
Turning the passenger's
temperature display off does not
shut the passenger's climate control
system off.
Manual Operation
O(Power):
Press to turn the
climate control system on or off.
When the climate control system is
turned off the air inlet defaults to
outside air.
D C(Fan Control): Press the
buttons to increase or decrease the
fan speed. Pressing either button
cancels automatic fan control. Press
AUTO to return to automatic
operation. The blower may reduce
during an Onstar
®session to limit
background noise.
