Headlamps On Reminder
If you leave the exterior lamp buttons for the headlamps
or parking lamps on, remove the key from the ignition
and open the driver's door, you will hear a continuous
warning chime. The chime will turn off when the
lamps are turned off.
Daytime Running Lamps
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the
day. DRL can be helpful in many different driving
conditions, but they can be especially helpful in the short
periods after dawn and before sunset. Fully functional
daytime running lamps are required on all vehicles
®rst sold in Canada.
A light sensor on top of the instrument panel monitors
the exterior light level for the operation of DRL and
Twilight Sentinel
ž, so be sure it isn't covered.
The DRL system will make your high-beam headlamps
turn on at reduced brightness in daylight when the
following conditions are met:
·The ignition is on,
·the exterior lamp button for the headlamps is
off and
·the transaxle is not in PARK (P).When the DRL are on, only your high-beam headlamps
will be on. The parking lamps, taillamps, sidemarker
and other lamps won't be on.
When it is dark enough outside, your low-beam
headlamps will come on. The other lamps that turn on
with your headlamps will also turn on. When it is
bright enough outside, the regular lamps will go off, and
your high-beam headlamps change to the reduced
brightness of DRL.
To turn off all exterior lighting at night when you are
parked, turn off the headlamps and move the Twilight
Sentinel
žlever all the way toward OFF. The exterior
lamps will turn back on automatically when you move
the transaxle out of PARK (P).
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Cornering Lamps
If your vehicle has this feature, the cornering lamps
come on when the headlamps or parking lamps are on
and you signal a turn with the multifunction lever.
They provide more light for cornering.

Twilight Sentinelž
Twilight Sentinelžturns your headlamps on and off by
sensing how dark it is outside.
The lever for this feature is
located to the left of the
steering column.
To operate it, leave the exterior lamp button off.
If you slide the lever all the way to MAX, your
headlamps will remain on for about three minutes after
you turn off your engine. As you slide the lever
toward OFF, the headlamps will turn off more quickly.
You can change this delay time from only a few seconds
to three minutes.
The exterior lamps can be completely shut off while the
vehicle is in PARK (P) by sliding the Twilight Sentinel
ž
lever all the way to OFF. To turn the exterior lamps back
on, slide the lever toward MAX again, or shift out of
PARK (P).
Park Lamp Override Feature
If the Twilight Sentinelžlighting is active, it can be
disabled by turning on the manual parking lamps. The
lighting will be disabled until the ignition is moved
from RUN or until the outside light level becomes
daylight. The outside light level changing to daylight will
cause the Twilight Sentinel
žfeature to deactivate.
The wiper-activated headlamps will override the twilight
disable feature.
Light Sensor
Your Twilight Sentinelž
and DRL work with the
light sensor located on top
of the instrument panel.
Don't cover it up. If you do, the sensor will read ªdarkº
and the Twilight Sentinel
žlighting will turn on.

Also in this mode, the RECIRC function is activated to
create the maximum cooling effect in the vehicle. If
RECIRC was activated before selecting MAX, the light
in the RECIRC button will go off. If RECIRC is
selected after MAX, the light in the RECIRC button will
not come on.
NORM (Normal Air Conditioning):This mode cools
the outside air entering your vehicle and directs it
through the instrument panel outlets.
BI-LEV (Bi-Level Air Conditioning):This mode directs
approximately half of the air to the instrument panel
outlets, and then directs most of the remaining air to the
¯oor outlets. Some air may be directed toward the
windshield. Cooler air is directed to the upper outlets
and warmer air to the ¯oor outlets. The air conditioning
compressor is on in this mode.
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, do the following:
1. Select the vent mode.
2. Select the recirculation mode.
3. Select MAX.
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.
Sensors
The solar sensor on your vehicle monitors the solar
radiation and the air inside of your vehicle, then uses the
information to maintain the selected temperature by
initiating needed adjustments to the temperature, the fan
speed and the air delivery system. The system may
also supply cooler air to the side of the vehicle facing the
sun. The recirculation mode will also be activated, as
necessary. Do not cover the solar sensor located in the
center of the instrument panel, near the windshield,
or the system will not work properly.
Defogging and Defrosting
Fog on the inside of windows is a result of high humidity
(moisture) condensing on the cool window glass. This
can be minimized if the climate control system is
used properly. This mode allows you to clear fog or
frost from your windshield.

1FRONT:Press the FRONT button to defrost the
windshield by directing air¯ow toward the windshield and
outboard outlets (for the side windows). To turn off
FRONT, press the AUTO or AIR FLOW buttons.
If the AIR FLOW up button is pressed while in the
FRONT defrost mode, the system will direct the
air toward the instrument panel outlets. If the AIR FLOW
down button is pressed while in the FRONT defrost
mode, the system will direct the air toward the ¯oor, and
the FRONT defrost mode will cancel. 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.
=REAR:Press this button to turn the rear window
defogger on or off. Be sure to clear as much snow from
the rear window as possible.
At speeds above 35 mph (55 km/h), the defogger will
operate continuously until you press the REAR
button again. After 10 minutes of driving below 35 mph
(55 km/h), the defogger will turn off automatically. If
you need additional warming time, push the button
again. The system will then operate for ®ve minutes
before going off by itself.
If your vehicle has heated outside rearview mirrors, the
mirrors will heat to help clear fog or frost from the
surface of the mirror when the rear window defogger
button is pressed.
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 defogger 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.

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.
If the light comes on while you are driving, 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. See
Towing
Your Vehicle on page 4-31.
{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.
Anti-Lock Brake System
Warning Light
With the anti-lock brake
system, the light(s) will
come on when your engine
is started and may stay
on for several seconds.
That's normal.
If the light stays on, turn the ignition to OFF. Or, if the
light comes on 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, or 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
Brake System Warning Light on page 3-37.
The anti-lock brake system warning light will come on
brie¯y when you turn the ignition key to RUN. This
is normal. If the light doesn't come on then, have it ®xed
so it will be ready to warn you if there is a problem.

Notice:Modi®cations 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.
Modi®cations 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 FlashingÐ A mis®re condition has been
detected. A mis®re increases vehicle emissions
and may damage the emission control system on
your vehicle. Diagnosis and service may be
required.
·Light On SteadyÐ 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 possible.
If the light stops ¯ashing and remains on steady, see ªIf
the Light Is On Steadyº 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 ªIf
the Light Is On Steadyº following. If the light is still
¯ashing, follow the previous steps, and see your dealer
for service as soon as possible.

With RDS, your radio can do the following:
·Seek to stations broadcasting the selected type of
programming
·Receive announcements concerning local and
national emergencies
·Display messages from radio stations
·Seek to stations with traffic announcements
This system relies upon receiving speci®c information
from these stations and will only work when the
information is available. In rare cases, a radio station
may broadcast incorrect information that will cause
the radio features to work improperly. If this happens,
contact the radio station.
While you are tuned to an RDS station, the station
