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

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,

Voltmeter Gage
When your engine is
not running, but the
ignition is in RUN,
this gage displays
the battery voltage
in DC volts.
When the engine is running, the gage shows the
condition of the charging system. The gage may
transition from a higher to lower or a lower to higher
reading. This is normal. Readings between the
low and high warning zones indicate the normal
operating range. The voltmeter gage may also read
lower when in fuel economy mode. This is normal.Readings in the low warning zone may occur
when a large number of electrical accessories
are operating in the vehicle and the engine is
left idling for an extended period. This condition
is normal since the charging system is not able
to provide full power at engine idle. As engine
speeds are increased, this condition should correct
itself as higher engine speeds allow the charging
system to create maximum power.
You can only drive for a short time with the
reading in either warning zone. If you must drive,
turn off all unnecessary accessories.
Readings in either warning zone indicate a
possible problem in the electrical system.
Have the vehicle serviced as soon as possible.

vehicle has a brake problem. A chime may
also sound when the light comes on.
Your vehicle’s hydraulic brake system is divided
into two parts. If one part is not 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 could be
a brake problem. Have your brake system
inspected right away.This light should come on brie y when you

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:Modi cations 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. Modi cations 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
