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 the
power that is 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,
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
driver. If so, a DIC message might
be displayed. If a battery message
is displayed, it is recommended that
the driver reduce the electrical loads
as much as possible. See
Driver
Information Center (DIC) 0129.
Battery Power Protection
The battery saver feature is
designed to protect the vehicle's
battery.
If some interior lamps are left on
and the ignition is turned off, the
battery rundown protection system
automatically turns the lamp off after
some time.
Exterior Lighting Battery
Saver
The exterior lamps turn off about
10 minutes after the ignition is
turned off, if the parking lamps or
headlamps have been manually left
on. This protects against draining the battery. To restart the 10-minute
timer, turn the exterior lamp control
to the off position and then back to
the parking lamp or headlamp
position.
To keep the lamps on for more than
10 minutes, the ignition must be in
the ACC/ACCESSORY or ON/RUN/
START position.

Rear Window Defogger
=(Rear Window Defogger) :
Press to turn the rear window
defogger on or off. An indicator light
on the button comes on to show that
the rear window defogger is on.
The rear window defogger can be
set to automatic operation. See
“Climate and Air Quality” under
Vehicle Personalization 0147.
When Auto Rear Defog is selected,
the rear window defogger turns on
automatically when the interior
temperature is about 4 °C (40 °F)
and below.
The upper gridlines on the rear
window are antenna lines and are
not intended to heat when the
defogger is activated.
The heated outside rearview mirrors
turn on when the rear window
defogger button is on and help to
clear fog or frost from the surface of
the mirrors.
Caution
Do not try to clear frost or other
material from the inside of the
front windshield and rear window
with a razor blade or anything
else that is sharp. This may
damage the rear window
defogger grid and affect the
radio's ability to pick up stations
clearly. The repairs would not be
covered by the vehicle warranty.
Driver and Passenger Heated and
Ventilated Seats (If Equipped) :
Press
Jorzto heat the driver or
passenger seat cushion and
seatback.
Press

or passenger seat.
The vehicle also has auto heated
seats that turn on when the vehicle
is on. The seats will activate at the
level required by the vehicle’s
interior temperature. To turn off,
press

Vehicle Personalization
0147 and
Heated and Ventilated Seats 014.
Remote Start Climate Control
Operation : If equipped with the
remote start feature, the climate
control system may run when the
vehicle is started remotely. The
system uses the driver ’s previous
settings to heat or cool the inside of
the vehicle. The rear defog may
come on during remote start based
on cold ambient conditions. The
rear defog indicator light does not
come on during a remote start.
If equipped with heated or ventilated
seats, they may come on during a
remote start. See Remote Vehicle
Start 033 and Heated and
Ventilated Seats 014.

174 Climate Controls
Sensor
The solar sensor, on top of the
instrument panel near the
windshield, monitors the solar heat.
The climate control system uses the
sensor information to adjust the
temperature, fan speed,
recirculation, and air delivery mode
for best comfort.
If the sensor is covered, the
automatic climate control system
may not work properly.Air Quality Sensor
If equipped with an air quality
sensor, the climate control system
adjusts to limit some exhaust fumes
from being pulled inside the vehicle.
Press the AUTO button on the
climate control to activate the air
quality sensor. Recirculation is
automatically selected when poor
quality air is detected. The air
quality sensor will not maintain
recirculation for an extended period
to prevent the air inside the vehicle
from becoming too dry or stuffy.
Under certain conditions, the air
quality sensor will not activate, such
as during cold weather or with
extreme odors. Press
@to
activate recirculation.
The air quality sensor system does
not protect against carbon monoxide
(CO), which you cannot see or
smell. See Engine Exhaust 0199.
The air quality sensor operation can
be adjusted, See “Climate and Air
Quality” underVehicle
Personalization 0147.

.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 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 Schedule 0329.
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.
