Reading Lamps
The reading lamps are located on
the overhead console.
To turn the reading lamps on or off,
press the button located next to
each lamp.
Electric Power
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 gage or a voltage
display on the Driver InformationCenter (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. SeeDIC Warnings and
Messages on page 3-49.

For vehicles with the remote start
feature, the rear defogger will
automatically turn on when remote
start is activated.
Notice:Do not use anything
sharp on the inside of the rear
window. If you do, you could cut
or damage the warming grid, and
the repairs would not be covered
by the vehicle warranty. Do not
attach a temporary vehicle
license, tape, a decal or anything
similar to the defogger grid.
Remote Start Climate Control
Operation
For vehicles with the remote start
feature and if it is activated, the
climate control system heats and
cools the inside of the vehicle using
the modes that were set before the
vehicle was turned off.Outlet Adjustment
Use the louvers located on the air
outlets to change the direction of the
air ow.
Operation Tips
Clear away any ice, snow,
or leaves from the air inlets
at the base of the vehicle that
may block the ow of air into
the vehicle.
Do not use any non-GM
approved hood de ectors
that could adversely affect the
performance of the system.
Keep the path under the front
seats clear of objects to help
circulate the air inside of
the vehicle more effectively.
Passenger Compartment
Air Filter
The lter removes dust, pollen, and
other airborne irritants from outside
air that is pulled into the vehicle.
The lter should be replaced as part
of routine scheduled maintenance.
SeeScheduled Maintenance on
page 6-3for replacement intervals.
To nd out what type of lter to use,
seeMaintenance Replacement Parts
on page 6-15.
The passenger compartment air
lter can be accessed by removing
the entire glove box.
1. Remove the six screws from
around the glove box and
detach the three inner clips
from the glove box.
