Exterior Lighting Battery Saver
If the headlamp or manual parking lamp control
has been left on, the exterior lamps will turn off
approximately 10 minutes after the ignition is turned to
OFF. This protects draining the battery in case you have
accidentally left the headlamps or parking lamps on. If
you need to purposely leave the lamps on for more than
10 minutes with the ignition in OFF or ACCESSORY,
turn the manual control knob off and then back on.
To delay the lamps from turning off, see ªTwilight
Sentinelº in the Index.
If the headlamp switch is turned on after the ignition key
is moved to either OFF or ACCESSORY, the lamps will
not time out.
Interior Lamps
Instrument Panel
Intensity/Brightness Control
The displays automatically dim when it becomes dark
outside and your lights are on. The displays
automatically brighten when it becomes light outside.
Backlighting will only remain active as long as the
parking lamps are on and it is dark outside.
Courtesy Lamps
The courtesy lamps are located on the ceiling above the
rear seat. These lamps come on with the control lamp
knob or when any door is opened and it is dark outside.
Puddle lamps are located on the bottom of the front and
rear door trim.
Illuminated Entry
The illuminated entry system turns on the courtesy
lamps and the backlighting to the door switches and to
the lamp control knob when a door is opened or if you
press a remote keyless entry transmitter unlock button.
If activated due to the transmitter, the lighting will
remain active for about 40 seconds. Since the
illuminated entry system uses the light sensor, it must be
dark outside in order for the courtesy lamps to turn on.
The courtesy lamps turn off approximately 25 seconds
after the last door is closed. They will dim to off if the
ignition key is placed in ON, or immediately deactivate
if the power locks are activated.

2-52
Parade Dimming
This feature prohibits dimming of the digital displays
and backlighting during daylight hours when the key is
in the ignition and the headlamps are on. This feature
operates with the light sensor for the Twilight Sentinel
and is fully automatic. When the light sensor reads
darkness outside and the park lamps are active, the
digital displays can be adjusted by turning the lamp
control knob counterclockwise to dim and clockwise to
brighten lighting.
Reading Lamps
The reading lamps are located on the overhead console
on the ceiling and in the rear door opening. These lamps
come on automatically when any door is opened and it is
dark outside. For manual operation, press the button to
turn them on. Press it again to turn them off.
If the reading lamps are left on, they automatically shut
off 10 minutes after the ignition has been turned off.
Map Lamps
These lamps are located in the front overhead console.
Press the button to turn them on. Press it again to turn
them off.

2-57
Convex Outside Mirror
Your passenger's side mirror is convex. A convex
mirror's surface is curved so you can see more from the
driver's seat.
CAUTION:
A convex mirror can make things (like other
vehicles) look farther away than they really are.
If you cut too sharply into the right lane, you
could hit a vehicle on your right. Check your
inside mirror or glance over your shoulder before
changing lanes.

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 also has a Driver Information Center (DIC)
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 ON, 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
70 seconds.
If the driver's belt is already buckled, neither the nor
the light will come on.
If the driver's belt is already buckled, the light will
come on briefly, but the chime will not sound.

2-75
Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows AIR BAG or the symbol of an air
bag. The system checks the air bag's electrical system for
malfunctions. The light tells you if there is an electrical
problem. The system check includes the air bag sensors,
the air bag modules, the wiring and the crash sensing and
diagnostic module. For more information on the air bag
system, see ªAir Bagº in the Index.
United States Canada
This light will come on when you start your vehicle, and
it will flash for a few seconds. Then the light should go
out. This means the system is ready.
If the air bag readiness light stays on after you start the
vehicle or comes on when you are driving, your air bag
system may not work properly. Have your vehicle
serviced right away.
CAUTION:
If the air bag readiness light stays on after you
start your vehicle, it means the air bag system
may not be working properly. The air bags in
your vehicle may not inflate in a crash, or they
could even inflate without a crash. To help avoid
injury to yourself or others, have your vehicle
serviced right away if the air bag readiness light
stays on after you start your vehicle.
The air bag readiness light should flash for a few
seconds when you turn the ignition key to ON. If the
light doesn't come on then, have it fixed so it will be
ready to warn you if there is a problem.

2-76
Charging System Light
When you turn the key to
ON, this light will come on
briefly to show that the
generator and battery
charging systems
are working.
If this light stays on, you need service and you should
take your vehicle to the dealer at once. To save your
battery until you get there, turn off all accessories.
Brake System Warning and Park Brake
Indicator Light
Your vehicle's hydraulic brake system is divided into
two parts. If one part isn't 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.
This light should come on
briefly when you turn the
ignition key to ON. If it
doesn't come on then, have
it fixed so it will be ready
to warn you if there's
a 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 floor.
It may take longer to stop. If the light is still on, have the
vehicle towed for service. (See ªTowing Your Vehicleº
in the Index.)

2-77
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 it 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, 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 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 ON. If the
light doesn't come on then, have it fixed so it will be
ready to warn you if there is a problem.

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 or
CHECK ENGINE 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.
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.

2-83
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.
Oil Pressure Light
This light tells you if there
could be a problem with
your engine oil pressure.
The light goes on when you turn your key to ON. It goes
off once you start your engine. That's a check to be sure
the light works. If it doesn't come on, be sure to have it
fixed so it will be there to warn you if something
goes wrong.
When the light comes on and stays on, it means that oil
isn't flowing through your engine properly. You could
be low on oil and you might have some other
system problem.

2-91
CHECK OIL LEVEL - 36: For correct operation of
the low oil sensing system, your vehicle should be on a
level surface. A false CHECK OIL LEVEL message
may appear if the vehicle is parked on grades. The oil
level sensing system does not check for actual oil level
if the engine has been off for a short period of time, and
the oil level is never sensed while the engine is running.
If the CHECK OIL LEVEL message appears, and your
vehicle has been parked on level ground with the engine
off for at least 30 minutes, the oil level should be
checked by observing the oil dipstick. Prior to checking
the oil level, be sure the engine has been off for a few
minutes and your vehicle is on a level surface. Then
check the dipstick and add oil if necessary. See ªEngine
Oilº in the Index.
CHECK WASHER FLUID
- 25: This message will
appear to indicate that the washer solvent container
needs refilling.
DRIVER DOOR AJAR
- 140: This message will
display anytime the key is in ON and the driver's door is
open or ajar. A chime will also sound when the vehicle's
speed is greater than 3 mph (4.8 km/h).DRIVER NO. X (1 OR 2) : This message will be
displayed with the key in ON and while entering Feature
Programming, but only if the vehicle is equipped with
memory seats. The message will show which driver is
activating the personalization feature. It will only stay
on for five seconds. This message can be customized for
you by your dealer.
ENGINE COOLANT HOT, IDLE ENGINE
- 44:
This message will appear when the engine coolant
temperature is over 262
F (128
C). Stop and allow your
vehicle to idle in PARK (P) until it cools down and the
message is removed. Do not increase engine speed
above a normal idle. If it does not cool down, turn off
the engine and have it serviced before driving it again.
Severe engine damage can result from an overheated
engine. See ªEngine Overheatingº in the Index.
ENGINE HOT
-AC OFF - 16: This message displays
when the engine coolant becomes hotter than the normal
operating temperature. To avoid added strain on a hot
engine, the air conditioning compressor is automatically
turned off. When the coolant temperature returns to
normal, the A/C operation will automatically resume.
You can continue to drive your vehicle. If this message
continues to appear, have the system repaired as soon as
possible to avoid compressor damage.
