Instrument Panel 3-11

Headlamps on Reminder
A headlamp reminder chime will
sound if the following conditions
are met:
The driver door is open.
Parking lamps or headlamps are
manually turned on.
The key is either not in the
ignition switch, or it is in the
LOCK/OFF position of the ignition
switch.
The headlamp reminder cannot be
turned off if the conditions listed
above are met.
In the automatic mode, the
headlamps turn off once the ignition
is in ACC/ACCESSORY.
Daytime Running
Lamps (DRL)
Daytime Running Lamps (DRL) can
make it easier for others to see
the front of your vehicle during the
day. Fully functional daytime
running lamps are required on all
vehicles rst sold in Canada.
The DRL system will come on when
the following conditions are met:
The ignition is on.
The exterior lamps control is
in AUTO.
The transmission is not in
P (Park), if the vehicle has
an automatic transmission.
The light sensor determines it is
daytime.When the DRL are on, no other
lamps are on. The instrument panel
will not be lit up either. For
vehicles rst sold in Canada, if

Automatic Headlamp
System
When it is dark enough outside,
the automatic headlamp system
will turn on after the transmission
has been shifted from P (Park) to
D (Drive). The headlamps, taillamps,
sidemarker, parking lamps, roof
marker lamps, and the instrument
panel lights turn on at normal
brightness. The radio lights will
become dimmer when the
headlights are off compared to
when the headlights are on.
The vehicle has a light sensor
located on the top of the instrument
panel. Do not cover the sensor,
or the system will be on whenever
the ignition is on.
The system can turn on the
headlamps when driving in a parking
garage, through a tunnel or when
there is overcast weather. This
is normal.There is a delay in the transition
between the daytime and nighttime
operation of the Daytime Running
Lamps (DRL) and the automatic
headlamp system so that driving
under bridges or bright overhead
street lights does not affect the
system. The DRL and automatic
headlamp system will only be
affected when the light sensor
detects a change in lighting lasting
longer than the delay.
If the vehicle is started in a dark
garage, the automatic headlamp
system will come on immediately.
Once the vehicle leaves the garage,
it will take about one minute for
the automatic headlamp system to
change to DRL if it is light
outside. During that delay, the
instrument panel cluster may not be
as bright as usual. Make sure the
instrument panel brightness
control is in the full bright position.
SeeInstrument Panel Brightness on
page 3-15.
Off-Road Lamps
The off-road lamps, if the vehicle
has them, provide auxiliary lighting
when the vehicle is used off
road. These lamps are not intended
to be used in place of existing
vehicle lighting. The lamps are not
to be used on any public street
or highway and are to be covered

3-16 Instrument Panel

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
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 fastenough 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 3-37.
Battery Run-Down
Protection
This feature shuts off the dome
lamp if it is left on for more
than 20 minutes when the ignition is
in LOCK/OFF. This helps to
prevent the battery from being
drained.
Instrument Panel 3-17

Rear Window Defogger
The rear window defogger uses a
warming grid to remove fog or
frost from the rear window when the
key is in the ignition and turned
to ON/RUN.
=(Rear Defogger):Press to turn
the rear window defogger on or
off. After the button is rst pressed
the rear window defogger stays
on for about 15 minutes. If turned on
again, the defogger only runs for
about seven and one-half minutes.
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.
Outlet Adjustment
Use the air outlets located in the
center and on the side of the
instrument panel to direct the
airow.
This vehicle has air outlets that
allow you to adjust the direction and
amount of airow inside the
vehicle. Move the louvers up or
down to change the direction of the
airow. Use the thumbwheel
under the outlets to change the
direction of the airow from left
to right.Operation TipsUse the recirculation mode for
maximum air conditioning
performance.
Clear away any ice, snow or
leaves from the air inlets at
the base of the windshield that
may block the ow of air into the
vehicle.
Use of non-GM approved hood
deectors may 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.
