Reverse Tilt Mirrors
If the vehicle is equipped with
memory mirrors, there is an option
to have the mirrors tilt down, when
in R (Reverse), to more easily see
the ground near the vehicle.
When the vehicle is shifted to
R (Reverse), both the driver and
passenger mirrors will tilt downward.
They will return to their previous
position when the vehicle is shifted
out of R (Reverse), the ignition is
turned to OFF, or the vehicle is left
in R (Reverse) for an extended
period of time.
This feature can be turned on or off.
See Vehicle Personalization on
page 5-43.

See OnStar Overview on page 14-1.
Do not spray glass cleaner directly
on the mirror. Use a soft towel
dampened with water.

Battery Load
Management
The vehicle has Electric Power
Management (EPM) that estimates
the battery's temperature and state
of charge. It then adjusts the voltage
for best performance and extended
life of the battery.
When the battery's state of charge
is low, the voltage is raised slightly
to quickly bring the charge back up.
When the state of charge is high,
the voltage is lowered slightly to
prevent overcharging. If the vehicle
has a voltmeter gauge or a voltage
display on the Driver Information
Center (DIC), you may see the
voltage move up or down. This is
normal. If there is a problem, an
alert will be displayed.
The battery can be discharged at
idle if the electrical loads are very
high. This is true for all vehicles. This is because the generator
(alternator) may not be spinning fast
enough at idle to produce all of the
power needed for very high
electrical loads.
A high electrical load occurs when
several of the following are on, such
as: headlamps, high beams, fog
lamps, rear window defogger,
climate control fan at high speed,
heated seats, engine cooling fans,
trailer loads, and loads plugged into
accessory power outlets.
EPM works to prevent excessive
discharge of the battery. It does this
by balancing the generator's output
and the vehicle's electrical needs.
It can increase engine idle speed to
generate more power whenever
needed. It can temporarily reduce
the power demands of some
accessories.
Normally, these actions occur in
steps or levels, without being
noticeable. In rare cases at the
highest levels of corrective action,
this action may be noticeable to the

Climate Control Influence on
eAssist Operation and Fuel
Economy (If Equipped)
The climate control system depends
on other vehicle systems for heat
and power input. Certain climate
control settings can lead to higher
fuel usage and/or fewer auto stops.
The following are climate control
settings that use more fuel:
.Comfort air conditioning mode.
.The 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.
Automatic Operation
The system automatically controls
the fan speed, air delivery, air
conditioning, and recirculation in
order to heat or cool the vehicle to
the desired temperature.
When the AUTO indicator light is
on, the system is in full automatic
operation. If the air delivery mode,
fan speed, recirculation, or air conditioning setting is adjusted, the
AUTO indicator turns off and the
selected settings will appear on the
display.
To place the system in automatic
mode do the following:
1. Press AUTO.
2. Set the temperature. Allow the
system time to stabilize. Adjust
the temperature as needed for
best comfort.
To improve fuel efficiency and to
cool the vehicle faster, recirculation
may be automatically selected in
warm weather. The recirculation
light will not come on. Press
@to
select recirculation; press it again to
select outside air.
Q/R(Driver and Passenger
Temperature Controls): The
temperature can be adjusted
separately for the driver and the
passenger. Press to increase or
decrease the temperature.

O(Power): Press to turn the fan off
or on.
Q 9 R(Fan Control): Press to
increase or decrease the fan speed.
The fan speed setting appears on
the main display. Pressing either
button cancels automatic fan control
and the fan is controlled manually.
Press AUTO to return to automatic
operation.
Air Delivery Mode Controls:
Press
-,Y, or[to change the
direction of the airflow. The current
mode appears in the display screen.
Pressing either button cancels
automatic air delivery control and the direction of the airflow is
controlled manually. Press AUTO to
return to automatic operation.
To change the current mode, select
one of the following:
-(Defog):
Clears the windows of
fog or moisture. Air is directed to the
windshield and floor outlets.
Y(Vent): Air is directed to the
instrument panel outlets.
[(Floor): Air is directed to the
floor outlets.
0MAX (Defrost): Clears the
windshield of fog or frost more
quickly. Air is directed to the
windshield.
For best results, clear all snow and
ice from the windshield before
defrosting.
For eAssist vehicles that have the
auto defog feature, auto stops can
occur in defrost mode. In this mode,
the auto stops are shorter and less
frequent than other air delivery
modes to prevent window fogging. A/C (Comfort Air Conditioning):
Press to turn the air conditioning
system on or off. If the climate
control system is turned off or the
outside temperature falls below
freezing, the air conditioner will
not run.
Pressing this button cancels
automatic air conditioning and turns
off the air conditioner. Press AUTO
to return to automatic operation and
the air conditioner runs
automatically as needed. When the
indicator light is on, the air
conditioner runs automatically to
cool the air inside the vehicle or to
dry the air needed to defog the
windshield faster.
For eAssist vehicles, an auto stop
may occur if the climate control
system determines the a/c
compressor can be shut off and still
maintain comfort levels with minimal
windshield fogging.
Eco A/C (For eAssist Vehicles):
Press to cycle between the off, eco
and comfort air conditioning modes.
