Entry Lighting
The vehicle has entry lighting.
When any door is opened, the dome lamps come on as
long as the dome override lamp override button is not
pressed in. When all the doors are closed, the lamps
stay on for a short period of time and then turn off
automatically. If you use the Remote Keyless Entry (RKE)
transmitter to unlock the vehicle, the interior lamps come
on for a short time whether or not the dome lamp override
is on.
Exit Lighting
With exit lighting, the interior lamps come on when you
remove the key from the ignition. If the dome override
is off, these lamps stay on for a short period of time
and then go out.
Reading Lamps
The reading lamps are located in the front console.
Press the lens on the lamps to turn the reading lamps
on or off.
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 put the charge back in. 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 loads are on: 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.
3-18

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 or
Service Battery Charging System. 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 3-53.Battery Run-Down Protection
This feature shuts off the dome, courtesy, and vanity
lamps if they are left on for more than 20 minutes
when the ignition is off. This will keep the battery
from running down.
If the battery run-down protection shuts off the interior
lamps, it may be necessary to do one of the following to
return to normal operation:
Shut off all lamps and close all doors.
Turn the ignition key to RUN.
This feature will also turn off the parking lamps and
headlamps under most circumstances, if they are left on.
If you would like to turn them back on, turn the exterior
lamps knob.
3-19

Rear Window Defogger
If your vehicle has the rear window defogger a warming
grid is used to remove fog on the rear window.
<(Rear):Press this button to turn the rear window
defogger on or off. An indicator light in the button
will come on to let you know that the rear window
defogger is active. The rear window defogger will
automatically turn off approximately ten minutes
after the button is pressed.
If your vehicle has heated mirrors, this button will
activate them.
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 your warranty. Do not attach a temporary
vehicle license, tape, a decal or anything similar to
the defogger grid.
Dual Automatic Climate Control
System
With this system you can control the heating, cooling
and ventilation for your vehicle. When your vehicle
is rst started and the climate control system is on,
or if the climate control system has been turned on,
the display will show the driver’s temperature setting for
ve seconds. Then it will show the outside temperature.
3-23

9(Off):Press this button to turn off the entire climate
control system. Outside air will still enter the vehicle, and
will be directed to the oor. Press the AUTO button, the
mode button, the fan arrows, or either temperature knob
to turn the system on.
C(Mode):Press this button to manually select the air
delivery mode to the oor, instrument panel, or windshield
outlets. The system will stay in the selected mode until
the mode button is pressed again or the AUTO button is
pressed.
Driver’s Side Temperature Knob:Turn this knob
clockwise or counterclockwise to raise or lower the
temperature on the driver’s side of the vehicle. The
display will show the temperature setting decreasing
or increasing and an arrow pointing toward the driver.
This knob can also adjust the passenger’s side
temperature setting if the two are linked.Passenger’s Side Temperature Knob:Turn this
knob clockwise or counterclockwise to manually raise or
lower the temperature on the passenger’s side of the
vehicle. The display will show the temperature setting
decreasing or increasing and an arrow pointing toward
the passenger. The passenger’s temperature setting
can be set to match and link to the driver’s temperature
setting by pressing and holding the AUTO button for
three seconds. When adjusting the driver’s side
temperature setting, the passenger’s side temperature
setting will follow and both arrows will appear on the
display. The passenger’s side temperature setting also
resets and relinks to the driver’s side temperature setting
if the vehicle has been off for more than three hours.
Outside Air Temperature Display
A new outside temperature reading will be displayed
if the vehicle has been off for more than three hours.
If the vehicle has been off for less than three hours,
the old temperature reading may be displayed because
underhood heat is affecting the true outside temperature.
Underhood heat can also affect the outside temperature
while the engine is running. It may also take
several minutes of driving before the display
updates to the actual outside temperature.
3-24

Automatic Operation
AUTO (Automatic):When automatic operation is
active, the system will control the inside temperature,
the air delivery mode, and the fan speed.
Use the steps below to place the entire system in
automatic mode:
1. Press the AUTO button.
When AUTO is selected, the air conditioning
operation and air outlet mode will be automatically
controlled. The air conditioning compressor will
run continuously when the outside temperature
is over approximately 40°F (4°C). The air inlet will
normally be set to outside air. If it’s hot outside,
the air inlet will automatically switch to recirculate
inside air to help quickly cool down your vehicle.
2. Set the driver’s and passenger’s temperature.
To nd your comfort setting, start with a 72°F (22°C)
temperature setting and allow about 20 minutes for
the system to adjust. Turn the driver’s or passenger’s
side temperature knob to adjust the temperature
setting as necessary. If you choose the temperature
setting of 60°F (15°C), the system will remain at
the maximum cooling setting. If you choose the
temperature setting of 90°F (32°C), the system will
remain at the maximum heat setting. Choosing either
maximum setting may not cause the vehicle to heat
or cool any faster.
Manual Operation
To change the current setting, select one of the
following:
w9x(Fan):This button allows you to manually
adjust the fan speed. Press the up arrow to increase fan
speed and the down arrow to decrease fan speed. The
display will change to show you the selected fan speed
and the driver’s side temperature setting for ve seconds.
C(Mode):Press this button to manually change the
direction of the airow in your vehicle. Keep pressing the
button until the desired mode appears on the display.
The display will change to show you the selected
air delivery mode and the driver’s temperature setting
for ve seconds.
H(Vent):This mode directs air to the instrument
panel outlets.
)(Bi-Level):This mode directs approximately half
of the air to the instrument panel outlets, then directs the
remaining air to the oor outlets. A little air is directed
toward the windshield and the side window outlets.
Cooler air is directed to the upper outlets and warmer
air to the oor outlets.
3-25

6(Floor):This mode directs most of the air to the
oor outlets. Some air also comes out of the defroster
and side window outlets. The recirculation button
cannot be selected in oor mode.
@(Recirculation):Press this button to turn
recirculation mode on or off. When this button is pressed,
an indicator light in the button will also come on to let you
know that it is activated. Recirculation mode is used to
recirculate the air inside of your vehicle. Use this mode to
help prevent outside odors and/or dust from entering your
vehicle or to help cool the air inside of your vehicle more
quickly. Recirculation mode can be used with vent and
bi-level modes, but it cannot be used with oor, defog or
defrost modes. Defog and defrost modes are described
later in this section.
If recirculation mode is selected with oor, defog, or
defrost modes, the indicator will ash three times and
then turn off indicating the selection is not available.
You may also notice that the air conditioning compressor
will run while in recirculation mode. This is normal and will
help to prevent fogging.
If the weather is cold and damp, the system may cause
the windows to fog while using recirculation mode. If the
windows do start to fog, select defog or defrost mode and
increase fan speed.
Recirculation mode, if selected, will be cleared when the
engine is turned off.
#A/C (Air Conditioning):Press this button to
manually turn the air conditioning system on or off.
When the system is on, the system will automatically
begin to cool and dehumidify the air inside of your
vehicle. The air conditioning symbol will appear on the
display when the air conditioning is on and will turn
off when the air conditioning is off.
If you turn the air conditioning off while in front defrost
or defog mode, the air conditioning symbol will turn
off, however, the A/C compressor will remain on to help
de-humidify the air inside the vehicle. If one of the
other modes is selected the compressor will then turn
the A/C off until it is selected again or the AUTO button
is pressed.
To avoid fogging the inside glass on rainy and humid
days at a temperature above freezing, press the air
conditioning button to run the A/C compressor. Also it is
best to avoid the use of the recirculation mode except
when maximum air conditioning performance is needed
or for short times to avoid exterior odors.
You may notice a slight change in engine performance
when the air-conditioning compressor shuts off and turns
on again. This is normal.

Speedometer and Odometer
The speedometer lets you see your speed in both miles
per hour (mph) and kilometers per hour (km/h).
The odometer shows how far your vehicle has been
driven, in either miles (used in the United States)
or kilometers (used in Canada).
The odometer mileage can be checked without the
vehicle running. Press the trip stem located on
the instrument panel cluster.
If your vehicle needs a new odometer installed, the new
one will be set to the correct mileage total of the old
odometer.
Trip Odometer
The trip odometer can tell you how far your vehicle has
been driven since you last set the trip odometer to zero.
The odometer works together with the Driver Information
Center (DIC). You can set a Trip A and Trip B odometer.
See “Trip Information” underDIC Operation and Displays
on page 3-50.
The odometer mileage can be checked without the
vehicle running. Press the trip stem on the instrument
panel cluster.
Tachometer
The tachometer displays
the engine speed in
revolutions per
minute (rpm).
Safety Belt Reminders
Safety Belt Reminder Light
When the engine is started, a chime will come on for
several seconds to remind people to fasten their safety
belts, unless the driver’s safety belt is already buckled.
The safety belt light will
also come on and stay on
for several seconds, then it
will ash for several more.
3-32

Voltmeter Gage
When your engine is not
running, but the ignition is
on, this gage displays the
battery voltage in DC volts.
When the engine is running, the gage shows the
condition of the charging system. The gage may
transition from a higher to lower or a lower to higher
reading, this is normal. Readings between the low
and high warning zones indicate the normal operating
range. The voltmeter gage may also read lower when
in fuel economy mode. This is normal.Readings in the low warning zone may occur when a
large number of electrical accessories are operating
in the vehicle and the engine is left idling for an
extended period. This condition is normal since the
charging system is not able to provide full power
at engine idle. As engine speeds are increased, this
condition should correct itself as higher engine speeds
allow the charging system to create maximum power.
You can only drive for a short time with the reading
in either warning zone. If you must drive, turn off
all unnecessary accessories.
Readings in either warning zone indicate a possible
problem in the electrical system. Have the vehicle
serviced as soon as possible.
3-37

Low Fuel Warning Light
The light next to the fuel gage will come on briey when
you are starting the engine.
This light comes on when the fuel tank is low on fuel.
To turn it off, add fuel to the fuel tank. SeeFuel on
page 5-5.
Check Gas Cap Light
If your vehicle has this
light, it will come on if your
gas cap is not securely
fastened.
SeeMalfunction Indicator Lamp on page 3-41for more
information.
Driver Information Center (DIC)
Your vehicle may have this feature. The Driver
Information Center (DIC) display is located on the
instrument panel cluster, below the speedometer.
If your vehicle has DIC buttons, they are located on
the steering wheel. The DIC can display information
such as the trip odometer, fuel economy, customization
features, and warning/status messages.
If your vehicle does not have DIC steering wheel
buttons, you will not have all of the features listed.
Scroll through the odometer and trip odometer by
pressing the trip odometer reset stem located on the
instrument panel cluster. Turn off, or acknowledge, DIC
messages by pressing the trip odometer reset stem.
SeeSpeedometer and Odometer on page 3-32for
information on features for vehicles without DIC buttons.

DIC Operation and Displays
The DIC comes on when the ignition is on. After a short
delay the DIC will display the information that was
last displayed before the engine was turned off.
If a problem is detected, a warning message will appear
on the display. Pressing the trip stem will acknowledge
any warning or service messages. Pressing any of
the DIC steering wheel buttons — trip information, fuel
information, customization, or select button — will
also acknowledge any warnings or service messages.
You should take any message that appears on the
display seriously and remember that clearing the
message will only make the message disappear,
not correct the problem.
The DIC has different modes which can be accessed by
pressing the four DIC buttons located on the steering
wheel. These buttons are trip information, fuel
information, customization, and select. The button
functions are detailed in the following pages.
