{CAUTION:
If the airbag readiness light stays on after
you start your vehicle, it means the airbag
system may not be working properly. The
airbags in your vehicle may not inate in
a crash, or they could even inate without
a crash. To help avoid injury to yourself
or others, have your vehicle serviced right
away if the airbag readiness light stays on
after you start your vehicle.
If the airbag readiness light stays on after you
start the vehicle or comes on when you are driving,
your airbag system may not work properly.
Have your vehicle serviced right away.
The airbag readiness light should ash for a few
seconds when you turn the ignition key to RUN.
If the light does not come on then, have it xed so
it will be ready to warn you if there is a problem.
Passenger Airbag Status Indicator
Your vehicle has the passenger sensing system.
Your rearview mirror has a passenger airbag
status indicator.
When the ignition key is turned to RUN or START,
the passenger airbag status indicator will light
ON and OFF, or the symbol for on and off,
for several seconds as a system check.
United States
Canada
203

If, after several seconds, all status indicator lights
remain on, or if there are no lights at all, there
may be a problem with the lights or the passenger
sensing system. See your dealer for service.
{CAUTION:
If the off indicator and the airbag
readiness light ever come on together,
it means that something may be wrong
with the airbag system. If this ever
happens, have the vehicle serviced
promptly, because an adult-size person
sitting in the right front passenger seat
may not have the protection of the frontal
airbag. SeeAirbag Readiness Light
on page 202.
Charging System Light
The charging system
light will come on briey
when you turn on
the ignition, but the
engine is not running,
as a check to show
you it is working.
It should go out once the engine is running.
If it stays on, or comes on while you are driving,
you may have a problem with the charging system.
It could indicate that you have problems with a
generator drive belt, or another electrical problem.
Have it checked right away. Driving while this
light is on could drain your battery.
If you must drive a short distance with the light on,
be certain to turn off all your accessories, such
as the radio and air conditioner.

Malfunction Indicator Lamp
Check Engine Light
Your vehicle has 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 awhile, the emission controls
might not work as well, your vehicle’s fuel
economy might not be as good, and the engine
might not run as smoothly. This could lead to
costly repairs that might not be covered by
your warranty.
Notice:Modications made to the engine,
transmission, 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 can
cause this light to come on. Modications to
these systems could lead to costly repairs not
covered by your warranty. This could also
result in a failure to pass a required Emission
Inspection/Maintenance test. SeeAccessories
and Modifications on page 386.
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 does not come
on, have it repaired. This light will also come on
during a malfunction in one of two ways:
