{CAUTION:
If the airbag readiness light ever comes
on when you have turned off the airbag, it
means that something may be wrong with
the airbag system. The right front
passenger’s airbag could inate even
though the switch is off. If this ever
happens, do not let anyone whom the
national government has identied as a
member of a passenger airbag risk group
sit in the right front passenger’s position
(for example, do not secure a rear-facing
child restraint in the right front
passenger’s seat) until you have your
vehicle serviced. SeeAirbag Off Switch on
page 84, for more on this, including
important safety information.
Charging System Light
The charging system
light will come on briey
when the ignition is on,
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 the battery.
When this light comes on the DIC will also display
the SERVICE BATTERY CHARGING SYSTEM
message. SeeDIC Warnings and Messages
on page 226for more information.
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.
209

Voltmeter Gage
When your engine is not
running, but the ignition
is in RUN, this gage
shows your battery’s
state of charge in
DC volts.
When the engine is running, the gage shows the
condition of the charging system. Readings
between the low and high warning zones indicate
the normal operating range.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 at
an idle 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.

DIC Warnings and Messages
Messages are displayed on the DIC to notify the
driver that the status of the vehicle has changed
and that some action may be needed by the driver
to correct the condition. Multiple messages may
appear one after another.
Some messages may not require immediate
action. Press any of the DIC buttons on the
steering wheel or the trip odometer reset stem
located on the instrument panel cluster to
acknowledge that you received the messages and
to clear them from the display.
Some messages cannot be cleared from the
display because they are more urgent. These
messages require action before they can be
removed from the DIC display. Take any messages
that appear on the display seriously and remember
that clearing the messages will only make the
messages disappear, not correct the problem.
The following are the possible messages that can
be displayed and some information about them.
BATTERY NOT CHARGING
This message displays if the battery is not
charging during operation. Driving with this
problem could drain the battery. Have the electrical
system checked as soon as possible by your
dealer. SeeCharging System Light on page 209
andVoltmeter Gage on page 210for more
information. Press any of the DIC buttons, or the
trip stem, to acknowledge this message and
clear it from the DIC display.
CHANGE ENGINE OIL
This message displays when the engine oil needs
to be changed. See “Engine Oil Life System”
underDIC Operation and Displays on page 222
andEngine Oil Life System on page 407for
information on how to reset the message. Also,
seeEngine Oil on page 404for more information.
This message clears itself after 10 seconds
until the next ignition cycle.
226

CHARGING SYSTEM FAILURE
On some vehicles, this message displays, a chime
sounds, and the charging system light on the
instrument panel cluster comes on if there
is a problem with the generator and battery
charging system. SeeCharging System Light on
page 209andVoltmeter Gage on page 210
for more information. Driving with this problem
could drain the battery. Turn off all unnecessary
accessories. Stop and turn off the vehicle as soon
as it is safe to do so. Have the electrical system
checked by your dealer immediately.
CHECK OIL LEVEL
This message displays if the oil level in the vehicle
is low. Check the oil level and correct it as
necessary. You may need to let the vehicle cool
or warm up and cycle the ignition to make sure this
message clears. Once the problem is corrected,
press any of the DIC buttons, or the trip stem,
to acknowledge this message and clear it from the
DIC display. This message clears itself after
10 seconds until the next ignition cycle.

uid level is low. Adding windshield washer uid to
the windshield washer uid reservoir clears the
message. SeeWindshield Washer Fluid on
page 426for more information. Press any of the
DIC buttons, or the trip stem, to acknowledge
this message and clear it from the DIC display.
This message clears itself after 10 seconds
until the next ignition cycle.

driver’s door is not fully closed and the vehicle
is in a drive gear. Stop and turn off the vehicle,
check the door for obstructions, and close the door
again. Check to see if the message still appears
on the DIC. Press any of the DIC buttons, or
the trip stem, to acknowledge this message and
