Emissions Inspection and Maintenance Programs
Some state/provincial and local governments have
or may begin programs to inspect the emission
control equipment on your vehicle. Failure to pass
this inspection could prevent you from getting a
vehicle registration.
Here are some things you need to know in order to help
your vehicle pass an inspection:
Your vehicle will not pass this inspection if the
SERVICE ENGINE SOON or CHECK ENGINE light is
on or not working properly.
Your vehicle will not pass this inspection if the OBD
(on
-board diagnostic) system determines that critical
emission control systems have not been completely
diagnosed by the system. The vehicle would be
considered not ready for inspection. This can happen if
you have recently replaced your battery or if your
battery has run down. The diagnostic system is designed
to evaluate critical emission control systems during
normal driving. This may take several days of routine
driving. If you have done this and your vehicle still does
not pass the inspection for lack of OBD system
readiness, see your dealer or qualified service center to
prepare the vehicle for inspection.
Fuel Gage
United States Canada
When the indicator nears empty, you still have a little
fuel left, but you should get more soon.
If your fuel is low, the warning message in the message
center will come on. See ªLow Fuel Warning Messageº
later in this section.
Your fuel gage tells you about how much fuel you have
left when the ignition is on.

2-112
Here are four things that some owners ask about. All
these things are normal and do not indicate that anything
is wrong with the fuel gage.

At the gas station, the gas pump shuts off before the
gage reads full.

It takes a little more (or less) fuel to fill up than the
gage reads. For example, the gage reads half full, but
it took more (or less) than half of the tank's capacity
to fill it.

The gage pointer may move while cornering, braking
or speeding up.

The gage may not indicate empty when the ignition
is turned off.
Message Center
The message center is located in the instrument
panel cluster. It gives you important safety and
maintenance facts.
Charging System Indicator Message
The charging system
battery symbol will come
on in the message center
when you turn on the
ignition as a check to
show you it is working.
It will remain on as long as the engine is not running. It
should go out once the engine is running. If it stays on,
or comes on while you are driving, you may have a
problem with the charging system. It could indicate that
you have problems with a generator drive belt, or
another electrical problem. Have it checked right away.
Driving while this indicator appears in the message
center could drain your battery.
If you must drive a short distance with the message on,
be certain to turn off all your accessories, such as the
radio and air conditioner.

2-117
Power Sliding Door Warning Message
United States Canada
This message will come on if the power sliding door is
not completely closed and the ignition is turned to RUN
or START.If you shift the transaxle out of PARK (P) while the
power sliding door is open or in the process of closing,
and the power sliding door is turned off, a buzzer will
sound. This is a warning that the power sliding door is
not completely closed.
CAUTION:
If you shift the transaxle out of PARK (P) and
accelerate before the power sliding door latches
closed, the door may reverse to the open position.
A child or others could fall out of the vehicle and
be injured. Always make sure the power sliding
door is closed and latched before you drive away.

2-118 Door Ajar Warning Message
United States Canada
This message will come on when the ignition is turned
to RUN or START and the driver's or passenger's door
is open.
It may also come on if a sliding door is not in the fully
latched position.

United States Canada
This message will come on when the ignition is turned
to RUN or START and the rear hatch is open.

2-119
PASS-Key
III Security Message
United States Canada
If you are ever driving and this message comes on and
stays on, you will be able to restart your engine if you
turn it off.
Your PASS
-Key III system, however, is not working
properly and must be serviced by your dealer. Your
vehicle is not protected by the PASS

need to reset the warning message. To reset the warning
message, turn the ignition off then back on. If the
message stays on, see your dealer right away.

2-120 AWD Disable Warning Message
(If Equipped)
United States Canada
You will receive this message when there is a spare tire
on the vehicle or when the anti
-lock brake system
warning light comes on.
The all
-wheel-drive system will be disabled until the
compact spare tire is replaced by a full
-size tire. If the
warning message is still on after putting on the full
-size
tire, you need to reset the warning message. To reset
the warning message, turn the ignition off and then back
on again. If the message stays on, see you dealer right
away. See ªAll

reading will toggle between displaying the outside
temperature and the word ªICEº for two minutes.
Compass Variance
Compass variance is the difference between magnetic
north and geographic north. In some areas of the
country, the difference is great enough to cause the
compass to give false readings. If this occurs, the
compass variance must be set.Setting the VarianceTurn the ignition on and cycle the DIC to the

Automatic Compass Calibration
The compass is self
-calibrating, which eliminates the
need to manually set the compass. When the vehicle is
new, the calibration process may not be complete. In
these cases the calibration symbol C will be displayed
where the compass reading is normally displayed.
To calibrate the compass, in an area free from large
metal objects, make three 360
turns. The calibration
symbol will turn off and the compass reading will
be displayed.
Manual Compass Calibration
If the compass appears erratic and the calibration
symbol does not appear, you must manually put the
compass into the calibration mode.
Turn the ignition on and cycle the DIC to the
Compass/Temperature mode. Press both the E/M and
MODE buttons simultaneously for at least 10 seconds
until the calibration symbol appears. Release both
buttons and complete three 360
turns in an area free
from large metal objects. The calibration symbol will
turn off and the compass reading will be displayed.Error Displays

An error of the vehicle's speed sensor or fuel sender
will cause
-E- to be displayed.

In the absence of vehicle communications, a
dash ª
--º is displayed.
If one of these error messages appear, see your dealer.
Trip Computer
There are five trip computer displays which may be
stepped through by pressing the MODE button. The
information will appear in the following order:

AVG ECON (Average Fuel Economy): This shows
the average fuel economy since the last reset.

INST ECON (Instantaneous Fuel Economy): This
shows fuel economy for the most recent second
of driving.

RANGE (Trip Range): This shows the estimated
distance that can be traveled with the remaining fuel.
The fuel economy used to calculate range is based on
the last few hours of driving.

FUEL USED (Trip Fuel Used): This shows the
accumulated fuel used since the last reset.

AVG SPEED (Average Speed): This shows the
average speed since the last reset.

Your vehicle is equipped with side window defogger
vents located on the top of the instrument panel. For
additional side window defogging, turn the mode knob
to the bi
-level setting and adjust the fan to the highest
speed. Aim the side vents on the instrument panel
toward the side windows. For increased airflow to the
side vents, close the center vents.
Operating the HVAC system in the recirculation mode
may cause fogging of the vehicle's windows when the
weather is cold and damp. To clear the fog, switch the
HVAC system to either the defog or defrost mode and
increase the fan speed. To avoid re
-fogging of the
windows, operate the HVAC system in the outside
air mode.
For additional information, refer to ªRecirculationº
earlier in this section.
Rear Window Defogger (If Equipped)
Press the REAR button
to warm the defogger grid
on the rear window and
to turn on the heated
outside rearview mirrors.
The system will turn off automatically after about
10 minutes of use. If you turn it on again, the defogger
will operate for about five minutes. You can also turn
the defogger off by turning off the ignition or by
pressing the button again.
Do not attach a temporary vehicle license across the
defogger grid on the rear window.
NOTICE:
Don't use a razor blade or something else sharp
on the inside of the rear window. If you do, you
could cut or damage the warming grid, and the
repairs wouldn't be covered by your warranty.

Ventilation Tips

Keep the hood and front air inlet free of ice, snow or
any other obstruction (such as leaves). This will
allow the heater and defroster to work much better,
reducing the chance of fogging the inside of
your windows.

When you enter a vehicle in cold weather, turn the
fan knob to 5, the highest setting, for a few moments
before driving off. This helps clear the intake ducts
of snow and moisture, and reduces the chance of
fogging the inside of your windows.

Keep the area around the base of the center
instrument panel console and the air path under the
front seats clear of objects. This helps air to circulate
throughout your vehicle.

In cold weather, operating the system in the
outside air mode will improve the time it takes to
warm the vehicle.Audio Systems
Your audio system has been designed to operate easily
and give years of listening pleasure. You will get the
most enjoyment out of it if you acquaint yourself with it
first. Find out what your audio system can do and how
to operate all of its controls to be sure you're getting the
most out of the advanced engineering that went into it.
Your vehicle may have a feature called Retained
Accessory Power (RAP). With RAP, you can play your
audio system even after the ignition is turned off. See
ªRetained Accessory Powerº in the Index.
Setting the Clock for Systems without
Radio Data System
Press and hold the HR or MIN arrow for two seconds.
Then press the HR arrow until the correct hour appears.
