maximum heat setting. Choosing either
maximum setting will not cause the vehicle
to heat or cool any faster.
Be careful not to cover the sensor located
on the top of the instrument panel near
the windshield. This sensor regulates air
temperature based on sun load, and also
turns on your headlamps.
Also be careful not to cover the sensor grille
on the lower right side of the climate
control faceplate. This senses the inside
vehicle temperature needed for proper
regulation.
To avoid blowing cold air at start-up in
cold weather, the system will delay turning
on the fan until warm air is available.
The length of delay depends on the engine
coolant temperature. Turning the fan knob
will override this delay and change the fan
to a selected speed.
If your vehicle has the remote start feature,
the climate control display will initially
show “AS” in place of the temperature to
indicate the remote start has been activated.The system will automatically regulate the
temperature according to the following:
If inside air temperature is below 72°F (22°C),
the system will automatically adjust to the
following settings: highest fan speed, defrost
mode, recirculation, and the full heat position.
If inside air temperature is above 79°F (26°C)
the system will automatically adjust to the
following settings: highest fan speed, panel
mode, recirculation, and full cold position.
If inside air temperature is between 72°F (22°C)
and 79°F (26°C), the system will adjust
automatically to the following settings: medium
fan speed, panel mode, recirculation, and the
full cold position.
The climate control will change back to manual
operation by turning on the vehicle with the key.

The heater works best if you keep the
windows closed while using it.

Warning Lights, Gages,
and Indicators
This part describes the warning lights and
gages on your vehicle. The pictures help to
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 the 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 the details show 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 as 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 vehicle’s warning lights
and gages. They can be a big help.
Instrument Panel Cluster
Your instrument panel cluster is designed to let
you know at a glance how your vehicle is running.
You’ll know how fast you’re going, how much
fuel you’re using, and many other things you will
need to drive safely and economically.
198

Tachometer
The tachometer shows your engine speed in
revolutions per minute (rpm).
Safety Belt Reminder Light
When the key is turned to ON or START,
a chime will come on for several seconds to
remind people to fasten their safety belts, unless
the driver’s safety belt is already buckled.
The safety belt light
will also come on
and stay on for
several seconds,
then it will ash for
several more.
This chime and light will be repeated if the driver
remains unbuckled and the vehicle is in motion.
If the driver’s belt is already buckled, neither
the chime nor the light will come on.
201

Charging System Light
The charging system
light will come on
briey when you turn
on the ignition, but
the engine is not
running, as a check to
show you it is working.
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
light is on could drain your battery.
If you must drive a short distance with the light on,
be certain to turn off all your accessories, such
as the radio and air conditioner.
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.
If the warning light comes on, there is a brake
problem. Have your brake system inspected
right away.

Anti-Lock Brake System
Warning Light
Your vehicle may have
the Anti-Lock Brake
System (ABS).
This light will come on when your engine is
started and may stay on for several seconds.
This is normal.If the light stays on, turn the ignition to off.
If the light comes on and the chime sounds 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. SeeBrake System
Warning Light on page 206earlier in this section.
The ABS warning light will come on briey
when you turn the ignition key to 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.
208

Engine Coolant Temperature
Warning Light
This light indicates
that the engine coolant
has overheated or
the radiator cooling fan
is not working.
This light will come on briey when you turn on
the ignition as a check to show you it is working.
If the light comes on and the vehicle has been
operating under normal driving conditions,
pull off the road, stop the vehicle, and turn off
the engine as soon as possible.
SeeCooling System on page 374for more
information.
Engine Coolant Temperature Gage
This gage shows the engine coolant temperature.
If the gage pointer moves into the red area,
the light comes on and you hear a chime, your
engine is too hot! It means that your engine
coolant has overheated.
If you have been operating your vehicle under
normal driving conditions and the gage reads hot,
you should pull off the road, stop your vehicle
and turn off the engine as soon as possible.
SeeEngine Overheating on page 371.

Malfunction Indicator Lamp
Check Engine Light
Your vehicle has
a computer which
monitors operation
of the fuel, ignition,
and emission control
systems.
This system is called OBD II (On-Board
Diagnostics-Second Generation) and is intended
to assure that emissions are at acceptable
levels for the life of the vehicle, helping to produce
a cleaner environment. The check engine light
comes on to indicate that there is a problem and
service is required. Malfunctions often will be
indicated by the system before any problem is
apparent. This may prevent more serious damage
to your vehicle. This system is also designed
to assist your service technician in correctly
diagnosing any malfunction.Notice:If you keep driving your vehicle with
this light on, after awhile, the emission controls
might not work as well, your vehicle’s fuel
economy might not be as good, and the engine
might not run as smoothly. This could lead
to costly repairs that might not be covered by
your warranty.
Notice:Modications made to the engine,
transaxle, exhaust, intake, or fuel system
of your vehicle or the replacement of the
original tires with other than those of the same
Tire Performance Criteria (TPC) can affect
your vehicle’s emission controls and may
cause this light to come on. Modications to
these systems could lead to costly repairs not
covered by your warranty. This may also
result in a failure to pass a required Emission
Inspection/Maintenance test. SeeAccessories
and Modifications on page 344.

This light should come on, as a check to show
you it is working, when the ignition is on and the
engine is not running. If the light does not
come on, have it repaired. This light will also
come on during a malfunction in one of two ways:
Light Flashing— A misre condition has
been detected. A misre increases vehicle
emissions and may damage the emission
control system on your vehicle. Diagnosis
and service may be required.
Light On Steady— An emission control
system malfunction has been detected on
your vehicle. Diagnosis and service may
be required.
If the Light is Flashing
The following may prevent more serious damage
to your vehicle:
Reducing vehicle speed
Avoiding hard accelerations
Avoiding steep uphill grades
If you are towing a trailer, reduce the
amount of cargo being hauled as soon
as it is possibleIf the light stops ashing and remains on steady,
see “If the Light Is On Steady” following.
If the light continues to ash, when it is safe to do
so, stop the vehicle. Find a safe place to park
your vehicle. Turn the key off, wait at least
10 seconds and restart the engine. If the light
remains on steady, see “If the Light Is On Steady”
following. If the light is still ashing, follow the
previous steps, and see your dealer for service
as soon as possible.
If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to fully
install the cap. SeeFilling the Tank on page 349.
The diagnostic system can determine if the
fuel cap has been left off or improperly installed.
A loose or missing fuel cap will allow fuel to
evaporate into the atmosphere. A few driving
trips with the cap properly installed should turn
the light off.
