LOCK (B): This is the only position in which you can
remove the key. This position locks your ignition, steering
wheel and transaxle. It's a theft
-deterrent feature.
OFF (C): This position lets you turn off the engine but
still turn the steering wheel. It doesn't lock the steering
wheel like LOCK and it doesn't send any electrical
power to the accessories. Use OFF if you must have
your vehicle in motion while the engine is not running.
RUN (D): This is the position the switch returns to after
you start the engine and release the switch. This is the
position for driving. Even when the engine is not
running, you can use RUN to operate your electrical
power accessories and to display some instrument panel
warning lights.
START (E): This position starts your engine. When the
engine starts, release the key. The ignition switch will
return to RUN for normal driving.NOTICE:
If your key seems stuck in LOCK and you can't
turn it, be sure you are using the correct key; if
so, is it all the way in? If it is, then turn the
steering wheel left and right while you turn the
key hard. But turn the key only with your hand.
Using a tool to force it could break the key or the
ignition switch. If none of this works, then your
vehicle needs service.

2-69 Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows 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.
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 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.

RUN, this light will come
on briefly, to show that your
generator and battery
charging systems
are working.

2-70 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.
This light should come on
when you turn the key to
START. 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 and chime come 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 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 and chime stay on after your parking
brake is fully released, it means you have a
brake problem.

2-71 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 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.
Traction Control System Warning Light
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 TRAC
CONT button located on the instrument panel, 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 and the warning light will come on. If
your brakes begin to overheat, the traction control
system will turn off and the warning light will come
on until your brakes cool down.

If the traction control system is affected by an
engine
-related problem, the system will turn off and
the warning light will come on.
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.
Engine Coolant Temperature
Warning Light
This light tells you that your
engine coolant has
overheated or your radiator
cooling fan is not working.
If you have been operating your vehicle under normal
driving conditions, you should pull off the road, stop
your vehicle and turn the engine off as soon as possible.

2-73 Engine Coolant Temperature Gage
Your vehicle has a gage that
shows the engine coolant
temperature. If the gage
pointer moves into the red
area, your engine is too hot!
This reading means the same thing as the warning light.
It means that your engine coolant has overheated. If you
have been operating your vehicle under normal driving
conditions, you should pull off the road, stop your
vehicle and turn off the engine as soon as possible.
The ªProblems on the Roadº section in this manual
explains what to do. See ªEngine Overheatingº in
the Index.
Low Coolant Warning Light
When this light comes on,
the cooling system is low
on coolant.
As a bulb check, it will come on for two to four seconds
and then go off when the ignition is in RUN. If the light
doesn't come on, have the vehicle serviced.
If the coolant level is low, the light will come back on
and a warning chime will sound. If this happens, see
ªEngine Coolantº in the Index for the proper cooling
system fill procedure.
After the coolant level is returned to its proper level, the
LOW COOLANT light will go off after 20 seconds or
remain off during the next ignition cycle.

2-74 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.
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.
