Section 3 Instrument Panel
3-1
Automatic Headlamp System
When it is dark enough outside, the automatic headlamp
system turns on the headlamps at the normal brightness
along with other lamps such as the taillamps, sidemarker,
parking lamps, and the instrument panel lights. The radio
lights will also be dim.
The vehicle has a light sensor on top of the instrument
panel that controls the automatic headlamp system.
Do not cover the sensor or the automatic headlamp
system will turn on when it is not needed.
There is a delay in the transition between the daytime
and nighttime operation of the DRL and the automatic
headlamp systems so that driving under bridges or
bright overhead street lights does not affect the system.
The DRL and automatic headlamp systems will only be
affected when the light sensor sees a change in lighting
lasting longer than this delay.
If vehicle is started in a dark garage, the automatic
headlamp system comes on immediately. Once the
vehicle leaves the garage, it takes 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 3-16.To idle the vehicle with the automatic headlamp system
off, turn the ignition on and set the exterior light switch to
the off/on position. For vehicles rst sold in Canada, the
transmission must stay in P (Park) for this function.
The regular headlamps should be used when needed.
Fog Lamps
For vehicles with fog lamps, the button for this feature is
located on the instrument panel, to the left of the
steering wheel.
The ignition must be on for the fog lamps to work.
#:Press to turn the fog lamps on or off. An indicator
light comes on when the fog lamps are on.
The parking lamps automatically turn on and off when
the fog lamps are turned on and off.
The fog lamps turn off while the high-beam headlamps
are turned on.
Some localities have laws that require the headlamps to
be on along with the fog lamps.
3-15
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
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 3-46.
3-17
If you try to connect equipment using more than
150 watts or a system fault is detected, a protection
circuit shuts off the power supply and the indicator light
turns off. To reset the circuit, unplug the item and plug it
back in or turn the Remote Accessory Power (RAP) off
and then back on. SeeRetained Accessory Power (RAP)
on page 2-23. The power restarts when equipment that
operates within the limit is plugged into the outlet and a
system fault is not detected.
The power outlet is not designed for the following
electrical equipment and may not work properly if these
items are plugged into the power outlet:
Equipment with high initial peak wattage such as:
compressor-driven refrigerators and electric
power tools.
Other equipment requiring an extremely stable
power supply such as: microcomputer-controlled
electric blankets, touch sensor lamps, etc.

Operation
Temperature Control:Turn clockwise or
counterclockwise to increase or decrease the
temperature inside the vehicle.
When it is cold outside 0°F (−18°C) or lower, use the
engine coolant heater, if vehicle has one, to provide
warmer air faster to the vehicle. An engine coolant
heater warms the coolant the engine uses that provides
heat to warm the inside of the vehicle. For more
information, seeEngine Coolant Heater on page 2-25.
9(Fan Control):Turn clockwise or counterclockwise
to increase or decrease the fan speed. The fan must
be on to run the air-conditioning compressor.
Air Delivery Mode Control:Turn clockwise or
counterclockwise to change the current air ow mode.
Select from the following:
H(Vent):Air is directed to the instrument panel
outlets.
)(Bi-Level):Air is divided between the instrument
panel and oor outlets. Some air will be directed toward
the side windows.
6(Floor):Air is directed to the oor outlets with some
air directed to the windshield and side window outlets.
-(Defog):This mode clears the windows of fog or
moisture. Air is directed to the windshield and oor
outlets, with some air directed to the side windows. When
this mode is selected, the system automatically turns off
recirculation and runs the air-conditioning compressor
unless the outside temperature is at or below freezing.
The air-conditioning compressor operates although the
indicator light is not on. The air-conditioning indicator light
turns off when defog is selected. If the air-conditioning
button is pressed while in defog mode, the indicator light
will turn on. If the button is pressed again, the light will
turn off. The recirculation mode cannot be selected while
in the defog mode. Do not drive the vehicle until all the
windows are clear.
1(Defrost):This mode quickly clears the windshield
of fog or frost. Air is directed to the windshield with some
air directed to the oor vents. In this mode, outside air is
pulled into the vehicle. The air-conditioning compressor
will not run unless the outside temperature is at or below
freezing. The air-conditioning compressor operates
although the indicator light is not on. The air-conditioning
indicator light turns off when defrost is selected. If the
air-conditioning button is pressed while in defrost mode,
the indicator light turns on. If the button is pressed again,
the light turns off. Recirculation cannot be selected while
in the defrost mode.

To help clear the windshield quickly, do the following:
1. Select
0.
2. Select the highest temperature.
3. Select the highest fan speed.
#(Air Conditioning):Press to turn the air conditioning
system on or off. An indicator light comes on to show
it is on.
The air-conditioning system removes moisture from the
air, so a small amount of water might drip under the
vehicle while it is idling or after the engine is turned off
is normal.
Maximum Air Conditioning
On hot days, open the windows to let hot inside air
escape; then close them. This helps reduce the time it
takes for the vehicle to cool down. It also helps the
air conditioning system operate more efficiently.
For quick cool down on hot days, do the following:
1. Select the
Cvent mode.
2. Select the highest fan speed.
3. Select
#air conditioning.
4. Select the
?recirculation mode.
5. Select the coolest temperature.Using these settings together for long periods of time can
cause the air inside of the vehicle to become too dry.
To prevent this from happening, after the air in the vehicle
has cooled, turn the recirculation mode off.
:(Outside Air):Press to turn the outside air mode
on. An indicator light comes on to show that it is on.
Air from outside the vehicle will circulate throughout
the vehicle. The outside air mode can be used with all
modes, but it cannot be used with the recirculation
mode. Press
:to cancel the recirculation mode.
?(Recirculation):Press to turn the recirculation
mode on. An indicator light comes on to show that it is
on. This mode recirculates and helps to quickly cool
the air inside the vehicle. It can be used to prevent
outside air and odors from entering the vehicle. The
recirculation indicator light blinks three times if you try to
use recirculation in a mode in which it cannot function.
Pressing this button cancels the outside air mode. When
switching to the defog or defrost modes the system
automatically moves from recirculation to outside air.
When the vehicle or fan is turned off and back on, the
system defaults to outside air automatically. Only use
recirculation mode when it is needed for comfort, since
window fogging can occur.
3-22
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
rear window defogger is on. Be sure to clear as much
snow from the rear window as possible.
If driving below 50 mph (80 km/h), the rear window
defogger turns off about 15 minutes after the button is
pressed. If turned on again, the defogger only runs for
about seven minutes before turning off. The defogger
can also be turned off by turning off the engine.
If the vehicle’s speed is maintained above 50 mph
(80 km/h), the rear window defogger remains on once
the button is pressed.
If the vehicle has heated outside mirrors, the surface of
the outside mirrors heat when the rear window defogger
is activated. SeeOutside Power Mirrors on page 2-39.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, when it is
activated the climate control system heats or cools the
inside of the vehicle using the modes that were set before
the vehicle was turned off. The climate control knobs will
remain active during a remote start. However, the climate
control buttons will be inactive until the ignition is turned
on by the key. If the fan is off, the climate control system
will not operate during remote start. SeeRemote Keyless
Entry (RKE) System Operation on page 2-5.
