the airbags may have also
damaged important functions in
the vehicle, such as the fuel
system, brake and steering
systems, etc. Even if the vehicle
appears to be drivable after a
moderate crash, there may be
concealed damage that could
make it difficult to safely operate
the vehicle.
Use caution if you should attempt
to restart the engine after a crash
has occurred.
In many crashes severe enough toinflate the airbag, windshields arebroken by vehicle deformation.Additional windshield breakage mayalso occur from the front outboardpassenger airbag.
.Airbags are designed to inflateonly once. After an airbaginflates, you will need some newparts for the airbag system.If you do not get them, the
airbag system will not be thereto help protect you in anothercrash. A new system will includeairbag modules and possiblyother parts. The service manualfor the vehicle covers the needto replace other parts.
.The vehicle has a crash sensingand diagnostic module whichrecords information after acrash. SeeVehicle DataRecording and Privacy0484andEvent DataRecorders0484.
.Let only qualified technicianswork on the airbag systems.Improper service can mean thatan airbag system will not workproperly. See your dealer forservice.
Airbag On-Off Switch
If the passenger side instrumentpanel endcap has the switchpictured in the following illustration,the vehicle has an airbag on-offswitch that you can use to manually
turn on or off the front outboardpassenger frontal airbag. SeeInstrument Panel06.
If the vehicle does not have anairbag on-off switch, it may have apassenger sensing system. SeePassenger Sensing System082.
This switch should only be turned tothe off position if the person in thefront outboard passenger position isamemberofapassengerriskgroupidentified by the nationalgovernment as follows:

When the ignition is on, the fuelgauge indicates about how muchfuel is left in the tank.
There is an arrow near the fuelgauge pointing to the side of thevehicle the fuel door is on.
When the indicator nears empty, thelow fuel light comes on. There still isalittlefuelleft,butthevehicleshould be refueled soon.
Here are four things that someowners ask about. None of theseshow a problem with the fuel gauge:
.At the service station, the fuelpump shuts off before the gaugereads full.
.It takes a little more or less fuelto fill up than the gaugeindicated. For example, thegauge may have indicated thetank was half full, but it actuallytook a little more or less thanhalf the tank's capacity to fillthe tank.
.The gauge moves a little whileturning a corner or speeding up.
.The gauge takes a few secondsto stabilize after the ignition isturned on, and goes back toempty when the ignition isturned off.
Engine Oil Pressure
Gauge
Metric
English
The engine oil pressure gaugeshows the engine oil pressurein kPa (kilopascals) or psi (poundsper square inch) when the engine isrunning.
Oil pressure can vary with enginespeed, outside temperature, coolanttemperature, and oil viscosity.

Voltmeter Gauge
When the ignition is on, this gaugeindicates the battery voltage.
When the engine is running, thisgauge shows the condition of thecharging system. The gauge cantransition from a higher to lower or alower to higher reading. This isnormal. If the vehicle is operatingoutside the normal operating range,the charging system light comes on.SeeCharging System Light0138for more information. The voltmetergauge may also read lower when infuel economy mode. This is normal.
Readings outside the normaloperating range can also occurwhen a large number of electricalaccessories are operating in thevehicle and the engine is left idlingfor an extended period. Thiscondition is normal since thecharging 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 only be driven for ashort time with the readings outsidethe normal operating range. If thevehicle must be driven, turn off allaccessories, such as the radio andair conditioner.
Readings outside the normaloperating range indicate a possibleproblem in the electrical system.Have the vehicle serviced as soonas possible.
Safety Belt Reminders

Light
There is a driver safety beltreminder light on the instrumentcluster.
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.

with the airbag system. To help
avoid injury to yourself or others,
have the vehicle serviced right
away. SeeAirbag Readiness
Light0135for more information,
including important safety
information.
Charging System Light
The charging system light comes onbriefly when the ignition is turnedon, but the engine is not running, asachecktoshowthelightisworking.It should go out when the engine isstarted.
If the light stays on, or comes onwhile driving, there may be aproblem with the electrical charging
system. Have it checked by yourdealer. Driving while this light is oncould drain the battery.
When this light comes on, or isflashing, the Driver InformationCenter (DIC) also displays amessage.
SeeBattery Voltage and ChargingMessages0150.
If a short distance must be drivenwith the light on, be sure to turn offall accessories, such as the radioand air conditioner.
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. SeeIgnitionPositions0268.
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
Modifications0352.
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 towing a trailer, reduce theamount of cargo being hauled assoon as possible.
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:
.If fuel has been added to thevehicle using the capless funneladapter, make sure that it hasbeen removed. See“Filling theTa n k w i t h a P o r t a b l e G a s C a n”underFilling the Tank0313.The diagnostic system candetect if the adapter has beenleft installed in the vehicle,allowing fuel to evaporate intothe atmosphere. A few drivingtrips with the adapter removedmay turn off the light.
.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. SeeFuel0311.
If the light remains on, see yourdealer.

When the Light Flashes First andThen Is On Steady
If the light flashes for about a minuteand then stays on, there may be aproblem with the TPMS. If theproblem is not corrected, the lightwill come on at every ignition cycle.SeeTire Pressure MonitorOperation0408.
Low Fuel Warning Light
This light is near the fuel gauge andcomes on briefly when the ignition isturned on as a check to show it isworking.
It also comes on when the fuel tankis low on fuel. The light turns offwhen fuel is added. If it does not,have the vehicle serviced.
Security Light
The security light should come onbriefly as the engine is started. If itdoes not come on, have the vehicle
serviced by your dealer. If thesystem is working normally, theindicator light turns off.
If the light stays on and the enginedoes not start, there could be aproblem with the theft-deterrentsystem. SeeImmobilizerOperation045.
