Running the Vehicle While Parked
It is better not to park with the engine running. But if you
ever have to, here are some things to know.
{CAUTION:
Idling a vehicle in an enclosed area with poor
ventilation is dangerous. Engine exhaust may
enter the vehicle. Engine exhaust contains Carbon
Monoxide (CO) which cannot be seen or smelled.
It can cause unconsciousness and even death.
Never run the engine in an enclosed area that
has no fresh air ventilation. For more information,
seeEngine Exhaust on page 2-32.
{CAUTION:
It can be dangerous to get out of the vehicle if the
automatic transmission shift lever is not fully in
P (Park) with the parking brake rmly set. The
vehicle can roll. Do not leave the vehicle when the
engine is running unless you have to. If you have
left the engine running, the vehicle can move
suddenly. You or others could be injured. To be
sure the vehicle will not move, even when you are
on fairly level ground, always set the parking
brake and move the shift lever to P (Park).
Follow the proper steps to be sure the vehicle will not
move. SeeShifting Into Park on page 2-28.

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 3-56.
Inadvertent Power Battery Saver
This feature is designed to protect your vehicle’s battery
against drainage from the interior lamps, or garage door
opener. When the ignition is turned off, the power to
these features will automatically turn off after 10 minutes.
Power will be restored for an additional 10 minutes if any
door is opened, the trunk is opened or the courtesy lamp
switch is turned on.
3-19

6(Floor):Air is directed to the oor outlets, with
some air directed to the windshield and side window
outlets.
If recirculation is selected while in this mode, it stays on
for three minutes to reduce windshield fogging.
-(Floor/Defog):This clears the windows of fog
or moisture. Air is directed to the windshield and side
window outlets and to the oor outlets. The system
runs the air conditioning compressor unless the outside
temperature is near or below freezing.
0(Defrost):This mode clears the windshield of fog or
frost more quickly. Air is directed to the windshield and
side window outlets. The system runs the air conditioning
compressor unless the outside temperature is near or
below freezing.
#(Air Conditioning):Press to turn the air conditioning
system on or off. An indicator light below the button
comes on to show that this mode is on. Air conditioning
can be selected in any mode as long as the fan knob
is not in the off position.
On hot days during the vehicle’s initial start-up, open
the windows to let hot inside air escape; then close them.
This helps to reduce the time it takes for the vehicle to
cool down. It also helps the system to operate more
efficiently.For quicker cool down on hot days, do the following:
1. Select
H.
2. Select
h.
3. Select
#.
4. Select the coolest temperature.
5. Select the highest fan speed.
The air-conditioning system removes moisture from
the air, so a small amount of water might drip under
the vehicle while idling or after turning off the engine.
This is normal.
h(Recirculation):Press to turn the recirculation
mode on. An indicator light below the button comes on
to show that this mode 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. This mode cannot be selected while in the defog
or defrost modes. If you try to select the recirculation
mode, the indicator light ashes three times and turns off.
Operation in this mode during periods of high humidity
and cool outside temperatures may result in increased
window fogging. If window fogging is experienced, select
the defrost mode.

Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
<(Rear Window Defogger):Press to turn the rear
window defogger on or off. An indicator light below the
button comes on to show that the rear window defogger is
on. Be sure to clear as much snow from the rear window
as possible.
The rear window defogger only works when the ignition is
in ON/RUN. The rear window defogger stays on for about
20 minutes after the button is pressed if traveling at slow
speeds. At higher vehicle speeds, the rear defogger may
stay on continuously. If turned on again, the defogger
only runs for about 10 minutes before turning off. The
defogger can be turned off by pressing the button again,
by turning the ignition to ACC/ACCESSORY or ON/RUN,
or by turning off the engine.
If the vehicle has heated outside rearview mirrors, the
mirrors heat to help clear fog or frost from the surface
of the mirror when the rear window defogger is on.
SeeOutside Heated Mirrors on page 2-37for more
information.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.
Dual Automatic Climate Control
System
The heating, cooling, and ventilation for the vehicle can
be controlled with this system.
For vehicles with the remote start feature and it is
activated, the climate control system heats or cools the
inside of the vehicle, with the settings used before the
vehicle was turned off. The heated seats, if the vehicle
has them, and the rear window defogger will be turned
on by the climate control system when it is cold outside.
The cooled seat setting is not activated during a remote
start. Normal operation of the system will return after
the key is turned to the ON/RUN position. SeeRemote
Keyless Entry (RKE) System Operation on page 2-5for
more information.

panel outlets and the oor outlets. In automatic operation,
cooler air is directed to the upper outlets and warmer air
to the oor outlets.
7(Floor):Air is directed to the oor outlets, with some
air directed to the windshield and side window outlets.
If recirculation is selected while in this mode, it stays on
for three minutes to reduce windshield fogging.
W(Floor/Defog):This mode clears the windows of
fog or moisture. Air is directed to the oor outlets, with
some air directed to the windshield and side window
outlets. The system turns off recirculation and runs
the air-conditioning compressor unless the outside
temperature is at or below freezing. The recirculation
mode cannot be selected while in the oor/defog mode.
0(Defrost):This mode removes fog or frost from the
windshield more quickly. Air is directed to the windshield
and the side window outlets. The system automatically
turns off recirculation and runs the air-conditioning
compressor, unless the outside temperature is at or
below freezing. Recirculation cannot be selected while
in the defrost mode.
#(Air Conditioning):Press to turn the air conditioning
system on or off and override the automatic system.
An indicator light below the button comes on to
show that this mode is on.
The air conditioning system removes moisture from the
air, so a small amount of water might drip under the

There is also an interior temperature sensor located
next to the steering wheel that measures the
temperature of the air inside the vehicle.
There is also an exterior temperature sensor located
behind the front grille. This sensor reads the outside air
temperature and helps maintain the temperature inside
the vehicle. Any cover on the front of the vehicle could
cause a false temperature reading to display.
In order to prevent false temperature readings at
startup, the displayed temperature will not change
until the following occurs:
Vehicle speed is above 10 mph (16 km/h) for
ve minutes.
Vehicle speed is above 32 mph (51 km/h) for
two and a half minutes.
The climate control system uses the information
from these sensors to maintain your comfort setting by
adjusting the outlet 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.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
<(Rear Defogger):Press to turn the rear window
defogger on or off. An indicator light below the button
comes on to show that the rear window defogger is on.
Be sure to clear as much snow from the rear window
as possible.
The rear window defogger only works when the ignition
is in ON/RUN. The rear window defogger stays on
for about 20 minutes after the button is pressed if the
vehicle is traveling at slower vehicle speeds. At higher
vehicle speeds the rear window defogger may stay on
continuously. If turned on again, the defogger only runs
for about 10 minutes before turning off. The defogger can
be turned off by pressing the button again, by turning the
ignition to ACC/ACCESSORY or ON/RUN, or by turning
off the engine.
The heated outside rearview mirrors will heat to help
clear fog or frost from the surface of the mirror when
the rear window defogger is on. SeeOutside Heated
Mirrors on page 2-37for more information.
Notice:Do not use a razor blade or sharp object to
clear the inside rear window. Do not adhere anything
to the defogger grid lines in the rear glass. These
actions may damage the rear defogger. Repairs
would not be covered by your warranty.
