2-55 Programming the Sunroof
If the battery on your vehicle has been recharged,
disconnected or is not working, you will need to
reprogram the sunroof following these steps. Refer to
the illustration under ªSunroofº for control
dial positions.
With your vehicle's ignition on:
1. If the sunroof is closed, turn the control dial to
position E. Hold the dial in position for about
five seconds.
If the sunroof is open, turn the control dial to E and
hold until the glass panel has closed. Now continue
holding the dial for approximately five
more seconds.
2. Turn the control dial to position G and hold until the
sunroof is fully tilted (about three seconds after the
motor has stopped).
3. Now turn the control dial to position E and keep
holding until the sunroof is fully closed (about three
seconds after the motor has stopped).4. Turn the control dial to position A and hold until the
sunroof is fully open (about three seconds after the
motor has stopped).
5. Turn to position E and keep holding the control dial
until the sunroof has fully closed (about three
seconds after the motor has stopped).
The sunroof is now programmed.
Note: If the sunroof keeps opening after you attempt to
close it once it has been programmed, you will need to
repeat Steps 2 through 5 (up to three times if needed).
If you are still having problems, consult your dealer
for service.
Also keep in mind that if something is in the way of the
sunroof closing during programming and you continue
to program the sunroof, the sunroof will only open or
close to the spot where the obstruction occurred. You
will need to reprogram the sunroof again, making sure
that the object has been removed.

This light will come on
when you start your engine,
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
engine or comes on when you are driving, your air bag
system may not work properly. Have your vehicle
serviced right away.
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.Charging System Indicator Light
When you turn the key to
START, 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 the
battery until you get there, turn off all accessories.
Voltmeter
You can read battery
voltage on the voltmeter. If
it reads less than 12 volts or
more than 16 volts while the
engine is running, and it
stays there, you may have a
problem with the electrical
charging system.

Have it checked right away. Driving with the voltmeter
reading in the lower warning zone could drain or
damage the battery. Driving with the voltmeter reading
in the upper warning zone could cause bulbs to burn out
(especially headlamp bulbs), various vehicle modules to
shut down (due to overload protection) and the
possibility of a battery acid leak.
If you idle the engine for a while, the voltmeter reading
might move into the red zone. If the reading stays in the
red zone while you are driving, you may have a problem
with the electrical charging system. Have it checked.
While the voltmeter reads in the red zone, the battery
may not be able to power certain electrical accessories,
like ABS. (If this happens, the ABS light will come on.
See ªAnti
-Lock Brakes System Warning Lightº in
this section.)
If you must drive a short distance with the voltmeter
reading in a warning zone, turn off all the accessories,
including the comfort controls and the audio system.
Brake System Warning 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.
United States Canada
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.)

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.

2-69 Engine Coolant Temperature Gage
This gage shows the engine
coolant temperature. If the
gage pointer moves into the
red area, the engine is
too hot!
This reading means the same thing as the warning
light
-- the engine coolant has overheated. You should
stop the car and turn the engine off as soon as possible.
See ªEngine Overheatingº in the Index.
Low Coolant Warning Light
This warning light should
come on for a few seconds
while you are starting the
engine. If the light doesn't
come on, have it repaired.
Your vehicle is equipped with a low coolant level sensor
(switch and float) that is designed to detect when your
vehicle's coolant level drops below the set limit. If the
low coolant level sensor (under the coolant surge tank)
detects that the level drops while the engine is running,
the low coolant indicator will light and remain lit until
the ignition switch is turned off. Check the coolant level
and add coolant as needed. The light should turn off as
soon as the coolant level is at its proper operating range.

2-70 Malfunction Indicator Lamp
(Check Engine 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 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 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, transmission,
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 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.
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.

When the light comes on and stays on, it means that oil
isn't flowing through the engine properly. You could
be low on oil and you might have some other
system problem.
CAUTION:
Don't keep driving if the oil pressure is low. If
you do, your engine can become so hot that it
catches fire. You or others could be burned.
Check your oil as soon as possible and have your
vehicle serviced.
NOTICE:
Damage to your engine from neglected oil
problems can be costly and is not covered by
your warranty.
Check Oil Light
This light will come on for
a few seconds when the
ignition is turned on. If the
light doesn't come on, have
it repaired.
If the light comes on while starting and stays on for
about one minute or comes on while driving, the engine
oil level should be checked. Prior to checking the oil
level, be sure your vehicle has been shut off for several
minutes and is on a level surface. Check the oil level and
bring it to the proper level. See ªEngine Oilº in
the Index.
Brake To Shift Light
This light will come on to
remind you that you must
press the brake pedal to
shift out of PARK (P).
