If the airow seems low when the fan speed is at the
highest setting, the passenger compartment air lter may
need to be replaced. For more information, see
Passenger Compartment Air Filter on page 3-31and
Scheduled Maintenance on page 6-4.
?(Recirculation):Press this button to turn the
recirculation mode on or off. When the climate control
system is in recirculation mode an indicator light
will come on. This mode prevents outside air from
entering your vehicle. It can be used to prevent outside
air and odors from entering your vehicle and to help
cool the air inside your vehicle more quickly.
Recirculation mode is not available in defrost or
defog mode.
^(Air Conditioning Off):Press this button to turn
the air conditioning compressor off. Press AUTO
to return to automatic operation. When in AUTO, the air
conditioning compressor will come on automatically,
as needed.
Air conditioning does not operate at temperatures below
about 35°F to 40°F (2°C to 4°C). In temperatures
above 40°F (4°C), the air conditioning cannot be turned
off in defrost and defog, as it helps to remove moisture
from the vehicle. It also helps to keep the windows clear.You may notice a slight change in engine performance
when the air-conditioning compressor shuts off and
turns on again. This is normal. The system is designed
to make adjustments to help with fuel economy while
still maintaining the selected temperature.
On hot days, open the windows to let hot inside air
escape; then close them. This helps to reduce the time
it takes for your vehicle to cool down. It also helps
the system to operate more efficiently.
For quick cool down on hot days press the AUTO
button and adjust the temperature to a cool, comfortable
setting. To achieve maximum cool down, do the
following:
1. Select the vent mode.
2. Select recirculation mode.
3. Select the A/C on.
4. Select the coolest temperature.
5. Select the highest fan speed.
Using these settings together for long periods of time
may cause the air inside of your vehicle to become too
dry. To prevent this from happening, after the air in
your vehicle has cooled, turn the recirculation mode off.
The air conditioning system removes moisture from
the air, so you may sometimes notice a small amount of
water dripping underneath your vehicle while idling or
after turning off the engine. This is normal.

1(Defrost):Pressing this button directs most of the
air to the windshield, with a small amount directed
to the side window outlets. The light on the button will
come on and the digital display will show the defrost
mode symbol and fan speed when the front defrost
mode is being used. In this mode, the system will
automatically turn off the recirculation and run the
air-conditioning compressor, unless the outside
temperature is at or below freezing. Recirculation
cannot be selected while in the defrost mode. Pressing
this button again will return the system to the last
operating mode.
For severe ice conditions, turn the driver’s temperature
knob to 90°F (32°C) while in defrost mode.
Do not drive the vehicle until all the windows are clear.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
The rear window defogger will only work when the
engine is running.
=(Rear Window Defogger):Press this button to turn
the rear window defogger on. Be sure to clear as
much snow from the rear window as possible. An
indicator light in the button will come on to let you know
that the rear window defogger is activated.
The rear window defogger will turn off about 10 minutes
after the button is pressed when traveling less than
30 mph (48 km/h). If turned on again, the defogger will
only run for about ve minutes before turning off.
The defogger can also be turned off by pressing the
button again or by turning off the engine.
Your vehicle has heated outside rearview mirrors. The
mirrors will heat to help clear fog or frost from the
surface of the mirrors when the rear window defog
button is pressed.
If your vehicle is equipped with the power convertible
top, the rear window defogger and heated mirrors
are automatically disabled when the power convertible
top is moving or down.
Notice:Do not use anything sharp on the inside of
the rear window. If you do, you could cut or
damage the warming grid, and the repairs would not
be covered by your warranty. Do not attach a
temporary vehicle license, tape, a decal or anything
similar to the defogger grid.

Warning Lights, Gages, and
Indicators
This part describes the warning lights and gages that
may be on your vehicle. The pictures will help you
locate them.Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause
an expensive repair or replacement. Paying attention to
your warning lights and gages could also save you
or others from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle’s functions. As you will
see in the details on the next few pages, some
warning lights come on briey when you start the
engine just to let you know they are working. If you are
familiar with this section, you should not be alarmed
when this happens.
Gages can indicate when there may be or is a problem
with one of your vehicle’s functions. Often gages
and warning lights work together to let you know when
there is a problem with your vehicle.
When one of the warning lights comes on and stays on
when you are driving, or when one of the gages
shows there may be a problem, check the section that
tells you what to do about it. Please follow this
manual’s advice. Waiting to do repairs can be
costly — and even dangerous. So please get to know
your warning lights and gages. They are a big help.
Your vehicle has a Driver Information Center that works
along with the warning lights and gages. SeeDriver
Information Center (DIC) on page 3-49.
3-32

Instrument Panel Cluster
Your instrument panel cluster and Driver Information Center (DIC) are designed to let you know at a glance how the
vehicle is running. You will know how fast you are going, about how much fuel you have left and many other
things you will need to know to drive safely and economically. The instrument panel cluster indicator warning lights,
gages and DIC messages are explained on the following pages.

Speedometer and Odometer
Your speedometer lets you see your speed in either
miles per hour (mph) or kilometers per hour (km/h). For
more information see “Personal Options” underDIC
Vehicle Personalization on page 3-69.
To read the odometer with the ignition off, turn on the
parking lamps.
You may wonder what happens if your vehicle needs a
new odometer installed. The mileage total of the
new odometer will be set to the original miles
(kilometers) of the old odometer. See your dealer if the
odometer must be replaced in your vehicle.
Tachometer
The tachometer displays the engine speed in thousands
of revolutions per minute (rpm).
Notice:Fuel will shut off at about 6600 rpm. If you
continue to drive your vehicle at the fuel shut off
rpm, you could damage your engine. Be sure
to operate your vehicle below the fuel shut off
rpm or reduce your rpm quickly when the fuel
shuts off.
Safety Belt Reminder Light
When the ignition is turned on, a chime will be provided
for several seconds to remind people to buckle their
safety belts. The driver safety belt light will also be
provided and stay on for several seconds, then it will ash
for several more. You should buckle your seat belt.
This chime and light will be
repeated if the driver
remains unbuckled and the
vehicle is in motion.
If the driver’s belt is buckled, neither the chime nor the
light will be provided.

Airbag Readiness Light
There is an airbag readiness light on the instrument
panel, which shows a deployed airbag symbol.
The system checks the airbag’s electrical system for
malfunctions. The light tells you if there is an electrical
problem. The system check includes the airbag
modules, the wiring and the diagnostic module. For
more information on the airbag system, seeAirbag
System on page 1-40.
This light will come on
when you start your
vehicle, and it will ash for
a few seconds. Then
the light should go out.
This means the system
is ready.
If the airbag readiness light stays on after you start the
vehicle or comes on when you are driving, your
airbag system may not work properly. Have your vehicle
serviced right away.{CAUTION:
If the airbag readiness light stays on after you
start your vehicle, it means the airbag system
may not be working properly. The airbags in
your vehicle may not inate in a crash, or they
could even inate without a crash. To help
avoid injury to yourself or others, have your
vehicle serviced right away if the airbag
readiness light stays on after you start your
vehicle.
The airbag readiness light should ash for a few
seconds when you turn the vehicle on. If the light does
not come on then, have it xed so it will be ready to
warn you if there is a problem.

Airbag Off Light
When you turn off the passenger’s frontal airbag and
side impact airbags (if equipped), an indicator on
the center console will light and stay lit to remind you
that the airbag or airbags have been turned off. This light
will go off when you turn the airbag or airbags on.
SeeAirbag Off Switch on page 1-48for more on this,
including important safety information.
A. Canadian Light
B. United States Light{CAUTION:
If the passenger’s frontal airbag and side
impact airbag (if equipped) are turned off for a
person who is not in a risk group identied by
the national government, that person will not
have the extra protection of an airbag. In a
crash, an airbag will not be able to inate and
help protect the person sitting there. Do not
turn off the passenger’s frontal airbag and side
impact airbag (if equipped) unless the person
sitting there is in a risk group. SeeAirbag Off
Switch on page 1-48for more on this,
including important safety information.
3-36

{CAUTION:
If the airbag readiness light ever comes on
when you have turned off the passenger’s
frontal airbag and side impact airbag
(if equipped), it means that something may
be wrong with the airbag system. The
passenger’s frontal airbag and side impact
airbag (if equipped) could inate even though
the switch is off. If this ever happens, do not
let anyone whom the national government has
identied as a member of a passenger airbag
risk group sit in the passenger’s position
(for example, do not secure a rear-facing child
restraint in your vehicle) until you have your
vehicle serviced. SeeAirbag Off Switch on
page 1-48.
Voltmeter Gage
The voltmeter shows the
voltage output of your
battery. When the engine
is running, it shows
the voltage output of the
charging system.
The reading will change as the rate of charge changes
(with engine speed, for example), but if the voltmeter
reads at 9 volts or below, your instrument panel cluster
and other systems may shut down. The Driver
Information Center (DIC) will read BATTERY VOLTAGE
LOW when your vehicle is at 10 volts or below. Have
it checked right away. Driving with the voltmeter reading
at 10 volts or below could drain your battery and
disable your vehicle.
3-37

One-to-Four Shift Light
(Manual Transmission)
When this light comes on,
you can only shift from
FIRST (1) to FOURTH (4)
instead of FIRST (1) to
SECOND (2).
You must complete the shift into FOURTH (4) to turn off
this feature. This helps you get the best possible fuel
economy.
After shifting to FOURTH (4), you may downshift to a
lower gear if you prefer.
Notice:Forcing the shift lever into any gear except
FOURTH (4) when the 1 TO 4 SHIFT light comes
on may damage the transmission. Shift only from
FIRST (1) to FOURTH (4) when the light comes on.
This light will come on when:
The engine coolant temperature is higher than
169°F (76°C),
you are going 15 to 19 mph (24 to 31 km/h) and
you are 21 percent throttle or less.
Brake System Warning Light
Your vehicle’s hydraulic brake system is divided into
two parts. If one part is not working, the other part can
still work and stop you. For good braking, though,
you need both parts working well.
This light should come on when you start the engine. If
it does not come on then, have it xed so it will be
ready to warn you if there is a problem.
If this warning light stays on after you start the engine,
the parking brake may still be set or there could be
a brake problem. Refer toParking Brake on page 2-30
to see if it is set. If the parking brake is not set, have
your brake system inspected right away.

If the light comes on while you are driving and you have
a CHECK BRAKE FLUID message showing on the
DIC, pull off the road and stop carefully. You may notice
that the pedal is harder to push. Or, the pedal may
go closer to the oor. It may take longer to stop. If the
light is still on, have the vehicle towed for service.
SeeTowing Your Vehicle on page 4-36.
{CAUTION:
Your brake system may not be working
properly if the brake system warning light is
on. Driving with the brake system warning light
on can lead to an accident. If the light is still
on after you have pulled off the road and
stopped carefully, have the vehicle towed for
service.
Anti-Lock Brake System Warning
Light
With the anti-lock brake
system, the light will come
on when your engine is
started and may stay on for
several seconds. That is
normal.
If the light stays on, turn the ignition off. Or, if the light
comes on when you are driving, stop as soon as
possible and turn the ignition off. Then start the engine
again to reset the system. If the light still stays on,
or comes on again while you are driving, your vehicle
needs service. If the regular brake system warning light
is not on, you still have brakes, but you do not have
anti-lock brakes. If the regular brake system warning
light is also on, you do not have anti-lock brakes
and there is a problem with your regular brakes. See
“SERVICE ANTILOCK BRAKES” underDIC Warnings
and Messages on page 3-54.
The anti-lock brake system warning light will come on
briey when you turn the ignition on. This is normal.
If the light does not come on then, have it xed so it will
be ready to warn you if there is a problem.
