Charging System Light
This light will come on briefly whenthe ignition is turned on, and theengine is not running, as a check toshow it is working.
It should go out when the engine isstarted. If it stays on, or comes onwhile driving, there may be aproblem with the electrical chargingsystem. Have it checked by yourdealer. Driving while this light is oncould drain the battery. If a shortdistance must be driven with thelight on, turn off all accessories,such as the radio and airconditioner, to help reduce the drainon the battery.
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 with the engine notrunning. SeeIgnition Positions (KeyAccess)0182orIgnition Positions(Keyless Access)0183.
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
an Emissions Inspection/
Maintenance test. See
Accessories and
Modifications0214.

If the light is flashing :Amalfunction has been detected thatcould damage the emission controlsystem and increase vehicleemissions. Diagnosis and servicemay be required.
To h e l p p r e v e n t d a m a g e , r e d u c evehicle speed and avoid hardaccelerations and uphill grades.
If the light continues to flash, find asafe place to park. Turn the vehicleoff and wait at least 10 secondsbefore restarting the engine. If thelight is still flashing, follow theprevious guidelines and see yourdealer for service as soon aspossible.
If the light is on steady :Amalfunction has been detected.Diagnosis and service may berequired.
Check the following:
.Alooseormissingfuelcapmaycause the light to come on. SeeFilling the Tank0209.Afewdriving trips with the capproperly installed may turn thelight off.
.Poor fuel quality can causeinefficient engine operation andpoor driveability, which may goaway once the engine is warmedup. If this occurs, change thefuel brand. It may require atleast one full tank of the properfuel to turn the light off. SeeFuel0207.
If the light remains on, see yourdealer.
Emissions Inspection and
Maintenance Programs
If the vehicle requires an EmissionsInspection/Maintenance test, thetest equipment will likely connect tothe vehicle's Data LinkConnector (DLC).
The DLC is under the instrumentpanel to the left of the steeringwheel. Connecting devices that are
not used to perform an EmissionsInspection/Maintenance test or toservice the vehicle may affectvehicle operation. SeeAdd-OnElectrical Equipment0211.Seeyour dealer if assistance is needed.
The vehicle may not passinspection if:
.The light is on when the engineis running.
.The light does not come onwhen the ignition is in ON/RUNwith the engine not running.
.Critical emission control systemshave not been completelydiagnosed. If this happens, thevehicle would not be ready forinspection and might requireseveral days of routine drivingbefore the system is ready forinspection. This can happen ifthe 12-volt battery has recentlybeen replaced or run down, or ifthe vehicle has been recentlyserviced.
See your dealer if the vehicle willnot pass or cannot be made readyfor the test.

Battery Load
Management
The vehicle has Electric PowerManagement (EPM) that estimatesthe battery's temperature and stateof charge. It then adjusts the voltagefor best performance and extendedlife 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 InformationCenter (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 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 to
generate 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.
Battery Power Protection
The battery saver feature isdesigned to protect the vehicle'sbattery.
If some interior lamps are left onand the ignition is turned off, thebattery rundown protection systemautomatically turns the lamp off aftersome time.
Exterior Lighting Battery
Saver
The exterior lamps turn off about10 minutes after the ignition isturned off, if the parking lamps orheadlamps have been manually lefton. This protects against draining

To k e e p t h e l a m p s o n f o r m o r e t h a n10 minutes, the ignition must be inthe ACC/ACCESSORY or ON/RUNposition.

.Turn off cruise control.
Blizzard Conditions
Stop the vehicle in a safe place andsignal for help. Stay with the vehicleunless there is help nearby.If possible, use RoadsideAssistance. SeeRoadsideAssistance Program0311.Togethelp and keep everyone in thevehicle safe:
.Turn on the hazard warningflashers.
.Tie a red cloth to an outsidemirror.
{Warning
Snow can trap engine exhaust
under the vehicle. This may
cause exhaust gases to get
inside. Engine exhaust contains
carbon monoxide (CO), which
cannot be seen or smelled. It can
cause unconsciousness and even
death.
If the vehicle is stuck in snow:
.Clear snow from the base ofthe vehicle, especially anyblocking the exhaust pipe.
.Open a window about 5 cm(2 in) on the vehicle sidethat is away from the wind,to bring in fresh air.
.Fully open the air outlets onor under the instrumentpanel.
.Adjust the climate controlsystem to circulate the airinside the vehicle and set

To s a v e f u e l , r u n t h e e n g i n e f o rshort periods to warm the vehicleand then shut the engine off andpartially close the window. Movingabout to keep warm also helps.
If it takes time for help to arrive,when running the engine, push theaccelerator pedal slightly so theengine runs faster than the idlespeed. This keeps the batterycharged to restart the vehicle and tosignal for help with the headlamps.Do this as little as possible, tosave fuel.
