Temperature Display
The temperature can be displayed by pressing the
TEMP button. Pressing the TEMP button once
briey, will toggle the temperature reading on
and off. To alternate the temperature reading
between Fahrenheit and Celsius, press and hold
the TEMP button until the display blinks F and C.
Press and release the TEMP button to toggle
between the Fahrenheit and Celsius readings.
After approximately four seconds of inactivity,
the display will stop blinking and display the last
selection made.
If an abnormal reading is displayed, for an
extended period of time, please consult your
dealer. Under certain circumstances, a delay in
updating the temperature is normal.
Compass Operation
Press the COMP button once briey to turn the
compass on or off.
When the ignition and the compass feature are
on, the compass will show two character boxes for
approximately two seconds. After two seconds,
the mirror will display the compass heading.
Compass Calibration
The compass may need calibration if one of the
following occurs:
If CAL is displayed while driving in the vehicle.
After approximately ve seconds, the display
does not show a compass heading (N for
North, for example), there may be a strong
magnetic eld interfering with the compass.
Such interference may be caused by a
magnetic antenna mount, magnetic note pad
holder or a similar magnetic item.
The compass does not display the correct
heading and the compass zone variance
is set correctly.
141

In order to calibrate, CAL must be displayed in the
mirror compass windows. If CAL is not displayed,
press and hold the COMP button until CAL is
displayed.
The compass can be calibrated by driving the
vehicle in circles at 5 mph (8 km/h) or less until the
display reads a direction.
Compass Variance
The mirror is set in zone eight upon leaving the
factory. It will be necessary to adjust the compass
to compensate for compass variance if you live
outside zone eight. Under certain circumstances,
as during a long distance cross-country trip, it
will be necessary to adjust for compass variance.
Compass variance is the difference between
earth’s magnetic north and true geographic north.
If not adjusted to account for compass variance,
your compass could give false readings.
To adjust for compass variance, do the following:
1. Find your current location and variance
zone number on the following zone map.
2. Press and hold the COMP button until a zone
number appears in the display.3. Press the COMP button on the bottom of the
mirror until the new zone number appears in
the display. After you stop pressing the
button, the display will show a compass
direction within a few seconds.
142

Passenger Airbag Indicator
The mirror may be equipped with a passenger
airbag indicator on the mirror glass, just above the
buttons. If the vehicle has this feature the mirror
will display the word ON, or an airbag symbol
in Canada, when the passenger airbag is enabled.
For more information seePassenger Sensing
System on page 80.
Cleaning the Mirror
When cleaning the mirror, use a paper towel or
similar material dampened with glass cleaner.
Do not spray glass cleaner directly on the mirror
as that may cause the liquid cleaner to enter
the mirror housing.
Outside Manual Mirrors
If the vehicle has the manual outside mirrors,
adjust each outside mirror so that a little of
the vehicle and the area behind it can be seen
while sitting in a comfortable, driving position.
Both mirrors can be manually folded inward
by pulling them towards the vehicle. Push the
mirrors away from the vehicle, to the normal
position, before driving.
Outside Power Mirrors
Your vehicle may have this feature. The power
mirror control is located on the driver’s door.
Turn the control knob left or right to select the
desired mirror. Then move the control knob to the
left or right or up or down to position the mirror
so that you can see a little of the outside of
the vehicle. After adjusting the position of the
mirrors, turn the knob to the center off position so
that the mirrors do not move.
If the travel position in any direction of the mirror
is reached, it will enter a ratcheting mode.
This action is harmless. It is a warning that the
mirror can go no further. To stop this action, back
the mirror up by moving the knob in the opposite
direction.
The mirrors can be manually folded inward to
prevent damage when going through an automatic
car wash. To fold, push the mirror toward the
vehicle. To return the mirror to its original position,
push outward. Be sure to return both mirrors to
their original unfolded position before driving.

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 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 224.

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.
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.
190

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.
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.
191

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.
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.
192

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.
193

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 221.
The odometer mileage can be checked without
the vehicle running. Press the trip stem on
the instrument panel cluster.
