When it's dark enough outside, your high-beam
headlamps will change to low
-beam headlamps at full
brightness. The other lamps that turn on with your
headlamps will also turn on. When it's bright enough
outside, the regular lamps will turn off, and your
high
-beam headlamps change to the reduced brightness
of DRL.
To idle your vehicle with the DRL off, shift the
transaxle into PARK (P). The DRL will stay off until
you shift out of PARK (P).
To turn off all exterior lighting at night when you are
parked, turn off the headlamps and move the Twilight
Sentinel control all the way to the left in the slider
control. When released, the control will return to the
Twilight Sentinel minimum delay position and the lights
will turn off.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Cornering Lamps
The cornering lamps are designed to come on when you
signal a turn. This will provide more light for cornering
at night.
Twilight Sentinel

Twilight Sentinel turns
your headlamps on and off
by sensing how dark it
is outside.
To operate this feature, slide the control to any position
to vary the lamp timeout.
If you move the control all the way to MAX, your lamps
will remain on for three minutes after you turn off your
engine. If you move the control almost all the way in the
other direction, so it's just on, the lamps will go off
quickly when you turn off your engine. You can set this
delay time from only a few seconds to three minutes.
Light Sensor
Your Twilight Sentinel and Daytime Running Lamps
work with the light sensor on top of the instrument
panel. Don't cover it up. If you do, it will read ªdarkº
and the headlamps will come on.

2-45
Interior Lamps
Instrument Panel Intensity Control
Instrument panel light brightness can be adjusted by
turning the headlamp knob counterclockwise
and clockwise.
Courtesy Lamps
When any door is opened, several lamps go on. They
make it easy for you to enter and leave the car. You can
also turn these lamps on by turning the headlamp knob
clockwise all the way past the normal stop.
Illuminated Entry System
When you open either front door or press the button
with the unlock symbol on the remote keyless entry
transmitter, the lamps inside your vehicle will turn on.
These lamps will turn off after about 40 seconds. These
lamps will also turn off if you start the engine or activate
the power door locks.
Delayed Entry Lighting
When you open the door, 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. Locking the doors
with the power door lock switch will override the
delayed entry lighting feature and the lamps will turn off
right away.
Using the remote keyless entry transmitter to lock the
door will not cancel delayed lighting.
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 handle or
lock switches.

Programming the HomeLink
Transmitter
Do not use the HomeLink Transmitter with any garage
door opener that does not have the ªstop and reverseº
safety feature. This includes any garage door opener
model manufactured before April 1, 1982.
Be sure that people and objects are clear of the garage
door you are programming.
Your vehicle's engine should be turned off while
programming the transmitter. Follow these steps to
program up to three channels:
1. If you have previously programmed a transmitter
channel, proceed to Step 2. Otherwise, hold down
the two outside buttons on the HomeLink
Transmitter until the indicator light begins to flash
rapidly (after 20 seconds). Then release the buttons.
This procedure initializes the memory and erases any
previous settings for all three channels.2. Decide which one of the three channels you want to
program. Hold the end of the hand
-held transmitter
about 2 to 5 inches (5 to 13 cm) away from the
surface of the HomeLink Transmitter so that you can
still see the indicator light.
3. Using both hands, press the hand
-held transmitter
button and the desired button on the HomeLink
Transmitter. Continue to press both buttons
through Step 4.
4. Hold down both buttons until you see the indicator light
on the HomeLink Transmitter flash slowly and then
rapidly. The rapid flashing indicates that the HomeLink
Transmitter has been programmed. Release both
buttons once the indicator light starts to flash rapidly.
If you have trouble programming the HomeLink
Transmitter, make sure that you have followed the
directions exactly as described. The HomeLink
Transmitter may not work with older garage door openers
that do not meet current Federal Consumer Safety
Standards. If you cannot program the transmitter after
repeated attempts, refer to ªRolling Code Programmingº
later in this section or contact the HomeLink Transmitter
manufacturer at 1
-800-355-3515.
Be sure to keep the original hand
-held transmitter
in case you need to erase and reprogram the
HomeLink Transmitter.

2-70 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).
Your vehicle has a tamper
-resistant odometer. You may
wonder what happens if your vehicle needs a new
odometer installed. If possible, the new one has to be set
to the same reading the old one had. If it can't be, then
it's set at zero and a label must be put on the driver's
door to show the old mileage reading and when the new
odometer was installed.
Trip Odometer
A trip odometer can tell how far you've driven since
you last set it back to zero. To reset it, push the RESET
button. The trip odometer is reset through the DIC if
your vehicle is equipped with this feature.
Tachometer
The tachometer tells you
how fast the engine is
running. It displays engine
speed in thousands of
revolutions per
minute (rpm).
NOTICE:
Do not operate the engine with the tachometer in
the red area, or engine damage may occur.

2-71
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 briefly when you start the
engine just to let you know they're 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's 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're a big help.
Your vehicle may also have a driver information center
that works along with the warning lights and gages.
See ªDriver Information Centerº in the Index.
Safety Belt Reminder Light
When the key is turned to RUN, a chime will come on
for about eight 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 about 20 seconds,
then it will flash for about
55 seconds.
If the driver's belt is already buckled, neither the chime
nor the light will come on.

2-74
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've
pulled off the road and stopped carefully, have
the vehicle towed for service.
When the ignition is on, the brake system warning light
will also come on when you set your parking brake.
The light will stay on if your parking brake doesn't
release fully. If you try to drive off with the parking
brake set, a chime will also come on until you release
the parking brake. If the light stays on after your
parking brake is fully released, it means you have a
brake problem.
Anti-Lock Brake System Warning Light
With the anti-lock brake
system, the light(s) will
come on when you start
your engine and may stay
on for several seconds.
That's normal.
If the light stays on and the chime sounds, turn the
ignition to OFF. Or, if the light comes on and the chime
sounds when you're 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 and the chime
sounds, or the light comes on again while you're driving,
your vehicle needs service. If the regular brake system
warning light isn't on, you still have brakes, but you
don't have anti
-lock brakes. If the regular brake system
warning light is also on, you don't have anti
-lock brakes
and there's a problem with your regular brakes. See
ªBrake System Warning Lightº earlier in this section.
The anti
-lock brake system warning light should come
on briefly when you turn the ignition key to RUN. If the
light doesn't come on then, have it fixed so it will be
ready to warn you if there is a problem.

2-75 Traction Control System Warning
Light (Option)
This warning light should
come on briefly as you start
the engine.
If the warning light doesn't come on then, have it fixed
so it will be ready to warn you if there's a problem. If it
stays on, or comes on when you're driving, there may be
a problem with your traction control system and your
vehicle may need service. When this warning light is on,
the system will not limit wheel spin. Adjust your
driving accordingly.The traction control system warning light may come on
for the following reasons:

If you turn the system off by pressing the button
located on the end of the shift lever, the warning
light will come on and stay on. To turn the system
back on, press the button again. The warning light
should go off. (See ªTraction Control Systemº
in the Index for more information.)

If there's a brake system problem that is specifically
related to traction control, the traction control system
will turn off, the warning light will come on and the
chime will sound.

If the traction control system is affected by an
engine
-related problem, the system will turn off,
the warning light will come on and the chime
will sound.
If the traction control system warning light comes on
and stays on for an extended period of time when the
system is turned on, your vehicle needs service.

2-76 Engine Coolant Temperature Gage
This gage measures the
temperature of the vehicle's
engine. If the pointer moves
into the red area, the engine
is too hot. A temperature
indicator light will turn on
and a chime will sound.
If you have been operating your vehicle under normal
driving conditions, and the temperature indicator light
comes on, you should pull off the road, stop your
vehicle and turn off the engine as soon as possible.
The section ªProblems on the Road,º in this manual
explains what to do. See ªEngine Overheatingº in
the Index.
Malfunction Indicator Lamp
(Service Engine Soon Light)
Your vehicle is equipped
with 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 SERVICE ENGINE SOON 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.

2-77
NOTICE:
If you keep driving your vehicle with this light
on, after a while, your emission controls may not
work as well, your fuel economy may not be as
good and your engine may not run as smoothly.
This could lead to costly repairs that may not be
covered by your warranty.
NOTICE:
Modifications made to the engine, transaxle,
exhaust 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 the SERVICE ENGINE SOON
light to come on. Modifications 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.
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 doesn't come on, have it repaired.
This light will also come on during a malfunction in
one of two ways:

Light Flashing
-- A misfire condition has been
detected. A misfire increases vehicle emissions and
may damage the emission control system on your
vehicle. Dealer or qualified service center diagnosis
and service may be required.

Light On Steady
-- An emission control system
malfunction has been detected on your vehicle.
Dealer or qualified service center 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 possible.

2-78
If the light stops flashing and remains on steady,
see ªIf the Light Is On Steadyº following.
If the light continues to flash, 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 ªIf the Light
Is On Steadyº following. If the light is still flashing,
follow the previous steps, and drive the vehicle to your
dealer or qualified service center for service.
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. See ªFilling Your Tankº in the Index.
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.Did you just drive through a deep puddle of water?
If so, your electrical system may be wet. The condition
will usually be corrected when the electrical system
dries out. A few driving trips should turn the light off.
Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel
(see ªFuelº in the Index). Poor fuel quality will cause
your engine not to run as efficiently as designed.
You may notice this as stalling after start
-up, stalling
when you put the vehicle into gear, misfiring, hesitation
on acceleration or stumbling on acceleration. (These
conditions may go away once the engine is warmed up.)
This will be detected by the system and cause the light
to turn on.
If you experience one or more of these conditions,
change the fuel brand you use. It will require at least one
full tank of the proper fuel to turn the light off.
If none of the above steps have made the light turn off,
have your dealer or qualified service center check the
vehicle. Your dealer has the proper test equipment and
diagnostic tools to fix any mechanical or electrical
problems that may have developed.
