Headlamp Washer
Your vehicle may have headlamp washers.
The headlamp washers clear debris from the
headlamp lenses.
The headlamp washers
are located beneath the
headlamps.
Press the washer button located at the end of the
windshield wiper lever, to wash the headlamps. Both the
headlamps and the windshield will be washed. After
the rst wash, the headlamps will not be washed until
the fth press of the windshield washer button.
The headlamps must be on to be washed. If the
headlamps are off, only the windshield will be washed
when the washer button is pressed. If the washer uid is
low, the headlamp washers will not work.

Reading Lamps
The reading lamps are located on the overhead console.
These lamps come on automatically when any door is
opened.
For manual operation, press the button next to each
lamp to turn it on or off.
If the reading lamps are left on, they automatically shut
off 10 minutes after the ignition has been turned 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.
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 3-56.

Climate Controls
Dual Climate Control System
The heating, cooling, and ventilation for the vehicle can
be controlled with this system.
O(Power):Press this button to turn the climate control
system on or off. When the climate control system is
turned off the air inlet defaults to outside air.
Automatic Operation
AUTO (Automatic):When this button is pressed and
the temperature is set, the system automatically
controls the inside temperature, the air delivery mode,
the air conditioning compressor, and the fan speed.When the indicator light is on, the system is in full
automatic operation. If the air delivery mode or fan
setting is manually adjusted, the auto indicator turns off
and displays will show the selected settings.
1. Press the AUTO button.
2. Adjust the temperature to a comfortable setting
between 60°F (15.5°C) and 90°F (32.2°C).
Choosing the coldest or warmest temperature setting
will not cause the system to heat or cool any faster.
If the system is set at the warmest temperature
setting, it remains in manual mode at that
temperature and it will not go into automatic mode.
In cold weather, the system starts at reduced fan
speeds to avoid blowing cold air into the vehicle
until warmer air is available. The system begins
blowing air at the oor but may change modes
automatically as the vehicle warms up to maintain
the chosen temperature setting. The length of
time the system needs to warm up depends on the
outside temperature and the length of time that
has elapsed since the vehicle was last driven.
3. Wait for the system to regulate. This may take from
10 to 30 minutes. Then adjust the temperature,
if necessary.
You can switch from English to metric units through the
Driver Information Center (DIC). SeeDIC Vehicle
Customization on page 3-69.

The air-conditioning system removes moisture from the
air, so a small amount of water might drip underneath
the vehicle while it is idling or after the engine is turned
off is normal.
Do not cover the solar sensor located in the center of
the instrument panel, near the windshield. For more
information on the solar sensor, see “Sensors” later in
this section.
PASS (Passenger Climate Control):Press this button
to set a different temperature for the passenger.
Then press the passenger temperature adjustment
buttons to select a comfortable setting.
Pressing the PASS button again automatically sets the
passenger’s temperature to the driver’s setting.
Turning the passenger’s temperature display off does
not shut the climate control system for the passenger off.
Q/R(Temperature Adjustment):The temperature
can be adjusted separately for the driver and the
passenger. Press the up or down arrow buttons to
increase or decrease the automatic temperature
settings.
Manual Operation
HG(Mode):Press theHorGbuttons to change the
current airow mode. The current mode selection
appears in the display screen. Changing the mode
cancels the automatic operation and the system goes
into manual mode. Press AUTO to return to automatic
operation.
The outboard air outlets always receive some airow in
every mode, except defrost. SeeOutlet Adjustment
on page 3-28to change this airow from the outboard
outlets.
Y(Vent):This mode directs air to the instrument panel
outlets.
\(Bi-Level):This mode splits the air between
the instrument panel outlets and the oor outlets.
In automatic operation, cooler air is directed to the
upper outlets and warmer air to the oor outlets.
[(Floor):This mode directs most of the air to the
oor outlets with some air directed to the outboard
outlets and a little air directed to the windshield.
The mode buttons can also be used to select the
defog and defrost modes. Information on defogging
and defrosting can be found later in this section.
3-25

Defogging and Defrosting
Fog on the inside of windows is a result of high humidity
(moisture) condensing on the cool window glass.
This can be minimized if the climate control system
is used properly. There are two modes to clear fog
from the windshield. Use the defog mode to clear the
windows of fog or moisture and warm the passengers.
Use the defrost mode to remove fog or frost from
the windshield more quickly.
HG(Mode):Press the mode buttons until defog
appears on the display.
-(Defog):This mode directs the air between the
windshield, oor outlets and side windows. When this
mode is selected, the system turns off recirculation and
runs the air-conditioning compressor unless the outside
temperature is at or below freezing. If recirculation mode
is selected while in defog mode, it will be cancelled after
10 minutes.
0(Defrost):Pressing defrost directs most of the air
to the windshield, with some air directed to the side
windows. In this mode, the system automatically turns off
recirculation and runs the air-conditioning compressor,
unless the outside temperature is at or below freezing.
This mode may also cause the fan speed and air
temperature to increase.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
The rear window defogger will only work when the
ignition is in ON/RUN.
=(Rear Window Defogger):Press this button to turn
the rear window defogger on or off. Be sure to clear
as much snow from the rear window as possible.
The rear window defogger turns off about 15 minutes
after the button is rst pressed if the vehicle is moving
at slower speeds. At higher speeds, the rear window
defogger may stay on continuously. With each additional
press, the defogger runs for about 10 minutes.
The defogger can also be turned off by pressing the
button again 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 button is on. SeeOutside
Heated Mirrors on page 2-51.
Notice:Do not try to clear frost or other material
from the inside of the front windshield and rear
window with a razor blade or anything else that is
sharp. This may damage the rear window defogger
grid and affect your radio’s ability to pick up
stations clearly. The repairs wouldn’t be covered by
your warranty.

Speedometer and Odometer
The speedometer lets you see your speed in either
miles per hour (mph) or 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).
If your vehicle has to have a new odometer installed,
the new one may read the correct mileage. This is
because your vehicle’s computer has stored the mileage
in memory.
While the Driver Shift Control (DSC) feature is active,
the odometer will change to show the gear range.
SeeAutomatic Transmission Operation on page 2-38
for more information.
Trip Odometers
The trip odometer can record the number of miles or
kilometers traveled for up to two trips.
The trip odometer is part of the Driver Information
Center (DIC), for more information seeDIC Operation
and Displays on page 3-48.
For vehicles that have the navigation system, see your
Navigation System manual for more information.
Tachometer
The tachometer
displays the engine
speed in revolutions per
minute (rpm).
Notice:If you operate the engine with the
tachometer in the shaded warning area, your vehicle
could be damaged, and the damages would not be
covered by your warranty. Do not operate the engine
with the tachometer in the shaded warning area.
Engine Speed Limiter
This feature prevents the engine from operating at too
many revolutions per minute (rpm). When the engine’s
rpms are too high, the throttle is closed to reduce speed.
If this is not sufficient, then the fuel supply to the engine
will be limited. When the rpms return to normal, the fuel
supply will return to normal. This helps prevent damage
to the engine.

Driver Information Center (DIC)
The Driver Information Center (DIC) gives you the
status of many of your vehicle’s systems. The DIC is
also used to display warning/status messages.
All messages appear in the DIC display located at the
bottom of the instrument panel cluster. The DIC buttons
are located on the instrument panel, next to the
steering wheel.
The DIC comes on when the ignition is on. After a short
delay, the DIC displays the information that was last
displayed before the engine was turned off.
The top line of the DIC display shows the DIC
information. The bottom line of the DIC display shows
the compass. The compass displays in the trip/fuel
menus and in some vehicle information menus.
If a problem is detected, a warning message appears
on the display. Take any message that appears on
the display seriously and remember that clearing
the message only makes the message disappear,
and does not correct the problem.
DIC Operation and Displays
The Driver Information
Center (DIC) has different
displays which can be
accessed by pressing the
DIC buttons located on
the instrument panel, next
to the steering wheel.
3Trip/Fuel:Press this button to scroll through the
trip and fuel displays. See “Trip/Fuel Display Menu
Items” following for more information on these displays.
TVehicle Information:Press this button to scroll
through the vehicle information displays. See “Vehicle

Trip/Fuel Display Menu Items
3
(Trip/Fuel):The following display menu items can
be displayed by pressing the trip/fuel button:
Odometer
This display shows the distance the vehicle has been
driven in either miles (mi) or kilometers (km).
Trip A or Trip B
These displays show the current distance traveled since
the last reset for each trip odometer in either miles (mi)
or kilometers (km). Both odometers can be used at
the same time. Each trip odometer can be reset to zero
separately by pressing and holding the set/reset button
for a few seconds while the desired trip odometer is
displayed.
Fuel Range
This display shows the approximate number of
remaining miles (mi) or kilometers (km) you can drive
without relling the fuel tank. This estimate is based
on the current driving conditions and changes if the
driving conditions change. For example, if you are
driving in traffic and making frequent stops, the display
may read one number, but if you enter the freeway,
the number may change even though you still have the
same amount of fuel in the fuel tank. This is because
different driving conditions produce different fuel
economies. Generally, freeway driving produces better
fuel economy than city driving.
Once the range drops below about 30 miles (48 km)
remaining, the display shows Low Range.
If your vehicle is low on fuel, the Fuel Level Low
message displays. See “Fuel Level Low” under
DIC Warnings and Messages on page 3-56for more
information.
