Compass Operation
Press the COMP switch once briefly 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.
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.Compass Calibration
If, after two seconds, the display does not show a
compass heading (ªNº for North, for example), there
may be a strong magnetic field interfering with the
compass. Such interference may be caused by a
magnetic antenna mount, magnetic note pad holder or a
similar magnetic item. If the letter ªCº should ever
appear in the compass window, the mirror may need
calibration.
The mirror can be calibrated in one of two ways:

Drive the vehicle in circles at five mph (8 km/h) or
less until the display reads a direction, or

Drive the vehicle on your everyday routine.

Press and release the TEMP switch to toggle the
temperature display between Fahrenheit or Celsius.
If an abnormal reading is displayed, please consult
your dealer.
Electrochromic Mirror Operation
The right side of the switch, labeled TEMP, located at
the bottom of the mirror turns the electrochromic inside
and outside mirrors on and off. An indicator light,
located to the right of the TEMP switch, will come on
when the electrochromic mirrors are turned on. To turn
the mirrors on, press and hold the TEMP button for six
seconds. To turn the mirrors off, press and hold the
TEMP button for six seconds. The indicator light will
turn off.

2-52 Electric Outside Rearview Mirrors
(If Equipped)
If you have electric mirrors, they can be adjusted to
point where you want from inside the vehicle.
Select the mirror you want
to move by moving the
center of the switch, located
on the driver's door armrest,
to L (left) or R (right).
Then, adjust the mirror angle by pressing the outer
arrows on the switch until the mirror is adjusted where
you want it.
Electrochromic Outside Rearview Mirrors
(If Equipped)
These outside rearview mirrors feature an auto-dimming
and defrost mode.To turn on the auto
-dimming feature, press and hold the
inside rearview mirror TEMP button for six seconds.
See ªElectrochromic Inside Rearview Mirror with
Compass and Temperature Displayº earlier in this
section for further information.
To turn on the defrost feature, press the rear window
defrost button. See ªRear Window Defoggerº in the
Index for further information.
Convex Outside Mirror
Your passenger's side mirror may be convex. A convex
mirror's surface is curved so you can see more from the
driver's seat.
CAUTION:
A convex mirror can make things (like other
vehicles) look farther away than they really are.
If you cut too sharply into the right lane, you
could hit a vehicle on your right. Check your
inside mirror or glance over your shoulder before
changing lanes.

Sun Visors
To block out glare, you can swing down the visors. You
can also swing them out to help block glare at the front
and side windows.
Your visor may have a strap to hold small items, such
as maps.
Some visors have an extender on the inside edge. When
the visor is down, pull the extender out for extra glare
coverage at the front or side.
Some visors have mirrors with lights. If the mirror has
lights, they will come on when you lift the mirror cover.
Universal Transmitter (If Equipped)
This transmitter allows you to consolidate the functions
of up to three individual hand
-held transmitters. It will
operate garage doors and gates, or with the accessory
package, other devices controlled by radio frequency
such as home/office lighting and security systems.

3-7 Air Conditioning
On hot days, open the windows long enough to let hot
air inside escape. This reduces the time it takes for your
vehicle to cool down. Then keep your windows closed
for the air conditioner to work its best.
The recirculation button, between the fan and
temperature knobs, allows the air inside your vehicle to
be recirculated. This setting helps to maximize your air
conditioner's performance and your vehicle's fuel
economy. This setting also cools the air the fastest and
can be used to keep unwanted odors and/or dust from
entering the vehicle. When using the air conditioner,
turn off recirculation after the vehicle reaches a
comfortable interior temperature. When the right knob
on the control panel is between HEATER and
DEFROST, the recirculation feature will not function.
The A/C button, between the temperature and mode
knobs, allows the air coming into your vehicle to be
cooled. This setting is useful for normal cooling on hot
days. When you use A/C with the recirculation button
pushed in, turn off recirculation as soon as the vehicle
reaches a comfortable interior temperature.With the A/C on, move the temperature knob to MAX
for maximum cooling. This setting also puts the system
in the recirculation mode and helps to maximize your air
conditioner's performance and your vehicle's fuel
economy. This setting also cools the air the fastest. After
the vehicle's interior reaches a comfortable temperature,
move the temperature knob clockwise to place the air
conditioning system in the normal mode.
Heating
The heater works best if you keep your windows closed
while using it. On cold days, use the HEATER or
VENT/HEAT setting with the temperature knob in the
red area.
If you use the engine coolant heater before starting your
engine in cold weather, 20
F (
-8
C) or lower, your
heating system will produce warmer air faster, to heat
the passenger compartment in cold weather.
The use of an engine coolant heater also reduces the
time it takes for the engine to reach normal operating
temperature, and shortens the time it takes the heater to
reach full output. For more information, see ªEngine
Coolant Heaterº in the Index.

3-8 Ventilation System
For mild outside temperatures when little heating or
cooling is needed, use VENT to direct outside air
through your vehicle. Air will flow through the
instrument panel outlets.
Your vehicle's ventilation system supplies outside air to
the inside of your vehicle when it is moving. With the
side windows closed, air will flow into the front air
inlet grilles, through the vehicle, and out the air
exhaust valves.
Outside air will also enter the vehicle when the heater or
the air conditioning fan is running, unless you have the
recirculation button pushed in. For more information on
the recirculation button, see ªAir Conditioningº earlier
in this section.
Your vehicle has air outlets in the center and on the sides
of your instrument panel. You can move the outlets from
side
-to-side or up and down to direct the flow of air, or
close the outlets altogether. When you close an outlet, it
will increase the flow of air coming out of any outlets
that are open. These outlets do not completely shut off
airflow when in a closed vent position.
