Instrument Panel 3-5

If the vehicle has a voltmeter gage
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 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, 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 driver. If so, a Driver
Information Center (DIC) message
might be displayed, such as
BATTERY SAVER ACTIVE,
BATTERY VOLTAGE LOW, or
LOW BATTERY. If this message is
displayed, it is recommended
that the driver reduce the electrical
loads as much as possible. See
DIC Warnings and Messages
on page 3-56.Battery Run-Down
Protection
This feature helps prevent the
battery from being drained, if the
interior courtesy lamps, reading/map
lamps, visor vanity lamps or trunk
lamp are accidentally left on.
If any of these lamps are left on,
they automatically turn off after
10 minutes, if the ignition is off.
The lamps will not come back on
again until one of the following
occurs:
The ignition is turned on.
The exterior lamps control is
turned off, then on again.
The headlamps will timeout after
10 minutes, if they are manually
turned on before the ignition is off.

adjusting the temperature, fan
speed, and the air delivery mode.
The system may also supply cooler
air to the side of the vehicle
facing the sun. The recirculation
mode will also be used as needed
to maintain cool outlet temperatures.
Outlet Adjustment
Use the slider switch in the center
of the outlet, to change the direction
of the air ow. Use the thumbwheel
near the outlet to control the
amount of air ow or to shut off the
airow completely.
Keep all outlets open whenever
possible for best system
performance.
Operation Tips

Clear away any ice, snow, or
leaves from the air inlets at
the base of the windshield that
can block the ow of air into
the vehicle.
Use of non-GM approved hood
deectors can adversely affect
the performance of the system.
Keep the path under all seats
clear of objects to help circulate
the air inside the vehicle
more effectively.
If fogging reoccurs while in vent
or bi-level modes with mild
temperature throughout the
vehicle, turn on the air conditioner
to reduce windshield fogging.

Warning Lights,
Gages, and Indicators
Warning lights and gages can
signal that something is wrong
before it becomes serious enough
to cause an expensive repair or
replacement. Paying attention to the
warning lights and gages could
prevent injury.
Warning lights come on when there
may be or is a problem with one
of the vehicle’s functions. Some
warning lights come on briey when
the engine is started to indicate
they are working.Gages can indicate when there may
be or is a problem with one of the
vehicle’s functions. Often gages and
warning lights work together to
indicate a problem with the vehicle.
When one of the warning lights
comes on and stays on while
driving, or when one of the gages
shows there may be a problem,
check the section that explains what
to do. Follow this manual’s advice.
Waiting to do repairs can be
costly and even dangerous.
