LOCK (B): This is the only position in which you can
remove the key. This position locks your ignition, steering
wheel and transaxle. It's a theft
-deterrent feature.
OFF (C): This position lets you turn off the engine but
still turn the steering wheel. It doesn't lock the steering
wheel like LOCK and it doesn't send any electrical
power to the accessories. Use OFF if you must have
your vehicle in motion while the engine is not running.
RUN (D): This is the position the switch returns to after
you start the engine and release the switch. This is the
position for driving. Even when the engine is not
running, you can use RUN to operate your electrical
power accessories and to display some instrument panel
warning lights.
START (E): This position starts your engine. When the
engine starts, release the key. The ignition switch will
return to RUN for normal driving.NOTICE:
If your key seems stuck in LOCK and you can't
turn it, be sure you are using the correct key; if
so, is it all the way in? If it is, then turn the
steering wheel left and right while you turn the
key hard. But turn the key only with your hand.
Using a tool to force it could break the key or the
ignition switch. If none of this works, then your
vehicle needs service.

Interior Lamps
Instrument Panel Brightness
By turning the headlamp knob you can make the
instrument panel lights brighten or dim. See
ªHeadlampsº in the Index.
Courtesy Lamps
When any door is opened, several lamps go on. They
make it easy for you to enter and leave the car. To turn
on these lamps without opening the door, turn the
headlamp knob to the right.
Illuminated Entry
Press the UNLOCK button on the remote keyless entry
transmitter and the interior courtesy lamps will come on
and stay on for up to one minute. The lamps will turn off
immediately when pressing the LOCK button on the
transmitter, starting the ignition or activating the power
door locks.
Delayed Entry Lighting
When you open the door to enter your vehicle, the
interior lamps will come on. When you close the door
with the ignition off, the interior lamps will stay on for
25 seconds or until the ignition is turned to an on
position. Note that locking the doors will override the
delayed entry lighting feature and the lamps will turn off
right away.
Theater Dimming
This feature allows for a three to five-second fade out of
the courtesy lamps instead of immediate turn off.
Delayed Exit Lighting
With this feature, the interior lamps will come on for
25 seconds after you remove the key from the ignition.
This will give you time to find the door pull handle or
lock switches when you exit the vehicle.
Parade Dimming
This feature prohibits the dimming of your instrument
panel displays during daylight while your headlamps are
on. This feature operates with the light sensor for the
twilight sentinel and is fully automatic. When the light
sensor reads darkness outside, you will be able to dim
your instrument panel displays once again.

Mirror Operation
To turn on the automatic dimming feature, press
AUTO. To turn off automatic dimming, press OFF.
The green indicator light will be illuminated when this
feature is active.
Time Delay
The automatic mirror has a time delay feature which
prevents unnecessary switching from the night back to
the day position. This delay prevents rapid changing of
the mirror as you drive under lights and through traffic.
Cleaning the Photocells
Use a cotton swab and glass cleaner to clean the
photocells when necessary.
Electrochromic Day/Night Rearview Mirror
with Compass (Option)
Your vehicle may have an electrochromic inside
rearview mirror with a compass.
When set in the MIRROR position, this mirror
automatically changes to reduce glare from headlamps
behind you. A time delay feature prevents rapid
changing from the day to night positions while driving
under lights and through traffic.
The mirror also includes an eight
-point compass display
in the upper right corner of the mirror face. When on,
the compass automatically calibrates as the vehicle
is driven.
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. Use a cotton swab and
glass cleaner to clean the photocells when necessary.

Mirror Operation
The right side of the button located at the bottom of the
mirror turns the electrochromic mirror on and off. To
turn on the automatic dimming feature, press MIRROR.
To turn off automatic dimming, press MIRROR again.
The green indicator light will be illuminated when this
feature is active.
Compass Operation
Press the COMPASS button once 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.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.
Compass Calibration
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 5 mph (8 km/h) or less
until the display reads a direction, or

Drive the vehicle on your everyday routine.
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:
1. Press and hold the COMPASS button located at the
bottom of the mirror until a zone number appears in
the display.
2. Find your current location and variance zone number
on the following zone map.3. Press the COMPASS 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. (This is the automatic calibration mode.
Drive in a circle to calibrate the mirror. See
ªCompass Calibrationº explained previously.)

2-67 Speedometer and Odometer
Your speedometer lets you see your speed in both miles
per hour (mph) and kilometers per hour (km/h). Your
odometer shows how far your vehicle has been driven,
in either miles (used in the United States) or kilometers
(used in Canada).
Trip Odometer
A trip odometer can tell you how many miles you have
driven since you last reset it back to zero.
To reset the trip
odometer, push the
TRIP RESET button.
Tachometer
The tachometer tells you
how fast the engine is
running. It displays engine
speed in revolutions per
minute (rpm).
NOTICE:
Do not operate the engine with the tachometer in
the red area, or engine damage may occur.

Comfort Controls
This section describes how to operate your climate
control system. Your climate control system uses
ozone
-friendly R-134a refrigerant.
Dual Automatic ComforTemp
Climate Control
Your vehicle has the Dual Automatic ComforTemp
Climate Control system. The following information tells
you how it works.
You will hear a beep each time a button is pushed and a
small light on the button will indicate which buttons are
active. The lights are on all buttons except TEMP, FAN
and AIR FLOW. The display will show fan speed,
comfort level setting and airflow direction for a few
seconds whenever AUTO is selected, and then it will
display the outside temperature. The outside temperature
reading is most accurate when the vehicle is moving.
During stops, the display shows the previous
temperature for best accuracy and system control.
If the display is flashing after the climate control system
is started, there is a problem with the system and you
should see your dealer for service.
Sun and temperature sensors automatically adjust the air
temperature, the airflow direction and the fan speed to
maintain your comfort setting. The system may supply
cooler air to the side toward the sun. Be careful not to
put anything over the sensors on top of the dash.

Temperature Button
To adjust the comfort level you want maintained inside
the vehicle, push the TEMP button. If you want a
warmer comfort level, push the red arrow. If you want a
cooler comfort level, push the blue arrow. Your comfort
setting is shown in the display.
Fan Button
The speed of the blower fan is controlled automatically
if you have the system set for AUTO. Pressing the
FAN button will display and hold the current blower
fan setting.
If you want the blower fan to run at a lower speed, push
the bottom of the FAN button. The fan speed will
decrease with every push of the button until the lowest
speed is reached. If you want to increase the fan speed,
push the top of the FAN button. Notice the fan
indicators in the display.
Mode Controls
Press the AIR FLOW button to deliver air through the
floor, middle or windshield outlets. The system will stay
in the selected mode until the AUTO button is pushed.
Press the up arrow on the AIR FLOW button to cycle
through the available modes.Automatic Operation
Press the AUTO button when you want the system to
automatically adjust the interior temperature to your
preference. When the system is set for automatic
operation, air will come from the floor, middle or
windshield outlets depending on the temperature inside
the vehicle, the outside temperature and sun load. Fan
speed will vary as the system gets to and maintains the
comfort setting you have selected through the use of the
TEMP button.
To find your comfort setting, start with the system
in AUTO mode and the TEMP button adjusted to a
display of 75
F (24
C), give the vehicle about
20 minutes to stabilize, then readjust your comfort
setting if necessary. The display will show the comfort
setting for a few seconds and then it will display the
outside temperature. If you want to see your current
automatic fan speed, airflow direction and comfort
setting, press the AUTO button.
In cold weather, the system will delay turning on the
fan, to avoid blowing cold air. The length of the delay
depends on the engine coolant temperature and the
outside temperature. Pushing the FAN, AIR FLOW or
FRONT buttons will override this delay, turn off the
AUTO setting and change the fan speed.
