The dome lamps will come on when you open a door
and will slowly dim to off when all doors are closed.
You can also turn the dome lamps on by turning the
thumbwheel, located next to the parking/headlamps
knob, all the way up. In this position, the dome lamps
will remain on whether a door is opened or closed.

Battery Run-Down Protection
This feature shuts off the dome, reading, glove box
and underhood lamps if they are left on for more than
20 minutes when the ignition is off. This will keep your
battery from running down.
Mirrors
Electrochromic Inside Rearview Mirror
with Compass and Temperature Display
When on, an electrochromic mirror automatically dims
to the proper level to minimize glare from lights behind
you after dark.
The mirror also includes a display of both the compass
and the temperature in the upper right corner of the
mirror face. The dual display can be turned on or off by
briefly pressing either the TEMP or COMP button.

2-43
Temperature Display
Pressing the TEMP button once briefly will toggle the
compass/temperature reading on and off. To alternate
the temperature reading between Fahrenheit and Celsius,
press and hold the TEMP button for three seconds until
the display blinks F
and C
. Press and release the
TEMP button to toggle between the Fahrenheit and
Celsius readings. After five seconds of inactivity, the
display will stop flashing and stay at the last setting.
If an abnormal reading is displayed, please consult
your dealer.Electrochromic Mirror Operation
The right side of the button, labeled TEMP and located
at the bottom of the mirror, turns the electrochromic
mirror on and off. An indicator light, located to the
right of the TEMP button, will come on when the
electrochromic mirror is turned on. To turn the mirror
on, press and hold the TEMP button for 15 seconds. To
turn the mirror off, press and hold the TEMP button for
15 seconds. The indicator light will turn off.
Compass Operation
With the ignition on, the compass will show
two character boxes. 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.

2-44
Compass Calibration
The compass may need calibration if:

After five 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.

The compass does not display the correct heading
and the compass zone variance is set correctly.
In order to calibrate, the letters ªCALº must be
displayed in the mirror compass windows. If ªCALº is
not displayed, push in the ªCOMPº button for
approximately eight seconds or until the letters ªCALº
are displayed.
The compass can be calibrated in one of two ways:

Drive the vehicle in circles at 5 mph (8 km/h) or less
until the display reads a direction, or

Drive the vehicle on your everyday routine and after
several turns the compass will become calibrated and
will display 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. Press and hold the COMP button located at the
bottom of the mirror for three seconds until a zone
number appears in the display.
2. Find your current location and variance zone number
on the following zone map.

2-45
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 in, the display will
show a compass direction within a few seconds.
Power Outside Rearview Mirrors
The control is located on the driver's door armrest.
Move the upper selector switch to the left or right to
choose the mirror you want to adjust, then press the
arrows located on the lower control pad to adjust

The mirrors include ground illumination lamps (puddle
lamps) in the base of the mirror. For more information
on these lamps, see ªPuddle Lampsº in the Index.

2-46 Driver's Outside Auto-Dimming
Rearview Mirror
The driver's outside mirror will adjust for the glare of
headlamps behind you. This feature is controlled by the
on and off settings on the electrochromic mirror. See
ªElectrochromic Inside Rearview Mirror with Compass
and Temperature Displayº earlier in this section.
Convex Outside Mirror
Your passenger's side mirror is 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.
Heated Outside Rearview Mirrors
The outside rearview mirrors have a defrost mode.
To turn on the defrost feature, press the rear window
defogger button. See ªRear Window Defoggerº in the
