Voltmeter Gauge
When the engine is not running, butthe ignition is on, this gauge showsthe battery's state of charge inDC volts.
When the engine is running, thegauge shows the condition of thecharging system. Readings betweenthe low and high warning zonesindicate the normal operating range.
Readings in the low warning zonemay occur when a large number ofelectrical accessories are operatingin the vehicle and the engine is leftat an idle for an extended period.This condition is normal since the
charging system is not able toprovide full power at engine idle. Asengine speeds are increased, thiscondition should correct itself ashigher engine speeds allow thecharging system to create maximumpower.
The vehicle can be only driven for ashort time with the reading in eitherwarning zone. If it must be driven,turn off all unnecessaryaccessories.
Readings in either warning zoneindicate a possible problem in theelectrical system. Have the vehicleserviced as soon as possible.
Safety Belt Reminders
Safety Belt Reminder Light
There is a safety belt reminder lighton the instrument cluster.
When the vehicle is started, thislight flashes and a chime may comeon to remind the driver to fastentheir safety belt. Then the light stayson solid until the belt is buckled.This cycle may continue severaltimes if the driver remains orbecomes unbuckled while thevehicle is moving.
If the driver safety belt is buckled,neither the light nor the chimecomes on.
Airbag Readiness Light
This light shows if there is anelectrical problem with the airbagsystem. The system check includesthe airbag sensor(s), thepretensioners (if equipped), theairbag modules, the wiring, and thecrash sensing and diagnosticmodule. For more information on theairbag system, seeAirbagSystem055.

{Warning
If the front outboard passenger
frontal airbag is turned off for a
person who is not in a risk group
identified by the national
government, that person will not
have the extra protection of an
airbag. In a crash, the airbag will
not be able to inflate and help
protect the person sitting there.

including important safety
information.
{Warning
If the airbag readiness light ever
comes on and stays on, it means
that something may be wrong
with the airbag system. For
example, the front outboard
passenger frontal airbag could
inflate even though the airbag
on-off switch is turned off.

others, have the vehicle serviced
right away. SeeAirbag Readiness
Light099for more information,
including important safety
information.
If the word ON or the on symbol islit, it means that the front outboardpassenger frontal airbag is enabled,and may inflate. SeeAirbag On-OffSwitch062for more information,including important safetyinformation.
Charging System Light
This light comes on briefly when theignition key is turned to START, butthe engine is not running, as acheck to show it is working.
If it does not, have the vehicleserviced by your dealer.
The light should go out once theengine starts. If it stays on,or comes on while driving, therecould be a problem with thecharging system. A charging systemmessage in the Driver Information

Center (DIC) can also appear. SeeBattery Voltage and ChargingMessages011 2for moreinformation. This light could indicatethat there are problems with agenerator drive belt, or that there isan electrical problem. Have itchecked right away. If the vehiclemust be driven a short distance withthe light on, turn off accessories,such as the radio and airconditioner.
Malfunction Indicator
Lamp (Check Engine
Light)
This light is part of the vehicle’semission control on-boarddiagnostic system. If this light is onwhile the engine is running, amalfunction has been detected andthe vehicle may require service. Thelight should come on to show that itis working when the ignition is inON/RUN and the engine is notrunning. SeeIgnitionPositions0176.
Malfunctions are often indicated bythe system before any problem isnoticeable. Being aware of the lightand seeking service promptly whenit comes on may prevent damage.
Caution
If the vehicle is driven continually
with this light on, the emission
control system may not work as
well, the fuel economy may be
lower, and the vehicle may not
run smoothly. This could lead to
costly repairs that might not be
covered by the vehicle warranty.
Caution
Modifications to the engine,
transmission, exhaust, intake,
or fuel system, or the use of
replacement tires that do not
meet the original tire
specifications, can cause this light
to come on. This could lead to
costly repairs not covered by the
vehicle warranty. This could also
affect the vehicle’sabilitytopass

Maintenance test. See
Accessories and
Modifications0216.
If the light is flashing :Amalfunction has been detected thatcould damage the emission controlsystem and increase vehicleemissions. Diagnosis and servicemay be required.

Reading Lamps
If equipped with reading lamps,press the button next to each lampto turn it on or off.
The vehicle may also have readinglamps in other locations. The lampscannot be adjusted.
Lighting Features
Entry/Exit Lighting
The vehicle has an illuminatedentry/exit feature.
The dome lamps come on if theE
DOME OFF button is in theextended position, when a door isopened, or the key is removed fromthe ignition.
Battery Load
Management
The vehicle may have ElectricPower Management (EPM) thatestimates the battery's temperatureand state of charge. It then adjuststhe voltage for best performanceand extended life of the battery.
When the battery's state of chargeis low, the voltage is raised slightlyto quickly bring the charge back up.When the state of charge is high,the voltage is lowered slightly toprevent overcharging. If the vehiclehas a voltmeter gauge or a voltagedisplay on the Driver Information
Center (DIC), you may see thevoltage move up or down. This isnormal. If there is a problem, analert will be displayed.
The battery can be discharged atidle if the electrical loads are veryhigh. This is true for all vehicles.This is because the generator(alternator) may not be spinning fastenough at idle to produce all thepower that is needed for very highelectrical loads.
Ahighelectricalloadoccurswhenseveral of the following are on, suchas: headlamps, high beams, foglamps, rear window defogger,climate control fan at high speed,heated seats, engine cooling fans,trailer loads, and loads plugged intoaccessory power outlets.
EPM works to prevent excessivedischarge of the battery. It does thisby balancing the generator's outputand the vehicle's electrical needs.It can increase engine idle speed togenerate more power, wheneverneeded. It can temporarily reducethe power demands of someaccessories.

Normally, these actions occur insteps or levels, without beingnoticeable. In rare cases at thehighest levels of corrective action,this action may be noticeable to thedriver. If so, a Driver InformationCenter (DIC) message might bedisplayed, such as SERVICEBATTERY CHARGING SYSTEM.If this messages displays, it isrecommended that the driver reducethe electrical loads as much aspossible. SeeBattery Voltage andCharging Messages011 2.
Battery Power Protection
This feature shuts off the domelamps if they are left on for morethan 10 minutes when the ignition isin LOCK/OFF. This helps to preventthe battery from running down.
