Servicing the
Airbag-Equipped Vehicle
Airbags affect how the vehicleshould be serviced. There are partsof the airbag system in severalplaces around the vehicle. Yourdealer and the service manual haveinformation about servicing thevehicle and the airbag system. Topurchase a service manual, seeService Publications OrderingInformation0321.
{Warning
For up to 10 seconds after the
vehicle is turned off and the
battery is disconnected, an airbag
can still inflate during improper
service. You can be injured if you
are close to an airbag when it
inflates. Avoid yellow connectors.
They are probably part of the
airbag system. Be sure to follow
proper service procedures, and
make sure the person performing
work for you is qualified to do so.
Adding Equipment to the
Airbag-Equipped Vehicle
Adding accessories that change thevehicle's frame, bumper system,height, front end, or side sheetmetal, may keep the airbag systemfrom working properly. Theoperation of the airbag system canalso be affected by changing anyparts of the front seats, safety belts,the airbag sensing and diagnosticmodule, steering wheel, instrumentpanel, any of the airbag modules,ceiling or pillar garnish trim, frontsensors, or airbag wiring.
Yo u r d e a l e r a n d t h e s e r v i c e m a n u a lhave information about the locationof the airbag sensors, sensing anddiagnostic module, and airbagwiring.
If the vehicle has rollover roof-railairbags, seeDifferent Size Tiresand Wheels0269for additionalimportant information.
If you have to modify your vehiclebecause you have a disability andyou have questions about whetherthe modifications will affect the
vehicle's airbag system, or if youhave questions about whether theairbag system will be affected if thevehicle is modified for any otherreason, call Customer Assistance.SeeCustomer AssistanceOffices0314.
Airbag System Check
The airbag system does not needregularly scheduled maintenance orreplacement. Make sure the airbagreadiness light is working. SeeAirbag Readiness Light099.
Caution
If an airbag covering is damaged,
opened, or broken, the airbag
may not work properly. Do not
open or break the airbag
coverings. If there are any
opened or broken airbag
coverings, have the airbag
covering and/or airbag module
replaced. For the location of the

130 Lighting
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.

Caution
Ignoring these steps could result
in costly damage to the vehicle
that would not be covered by the
vehicle warranty. Trying to start
the vehicle by pushing or pulling it
will not work, and it could damage
the vehicle.
1. Check the other vehicle.It must have a 12-volt batterywith a negative ground system.
Caution
If the other vehicle does not have
a12-voltsystemwithanegative
ground, both vehicles can be
damaged. Only use a vehicle that
has a 12-volt system with a
negative ground for jump starting.
2. Get the vehicles close enoughso the jumper cables canreach, but be sure the vehiclesare not touching each other.If they are, it could cause a
ground connection you do notwant. You would not be able tostart your vehicle, and the badgrounding could damage theelectrical systems.
To a v o i d t h e p o s s i b i l i t y o f t h evehicles rolling, set the parkingbrake firmly on both vehiclesinvolved in the jump startprocedure. Put an automatictransmission in P (Park) or amanual transmission in Neutralbefore setting the parkingbrake.
Caution
If any accessories are left on or
plugged in during the jump
starting procedure, they could be
damaged. The repairs would not
be covered by the vehicle
warranty. Whenever possible, turn
off or unplug all accessories on
either vehicle when jump starting.
3. Turn off the ignition on bothvehicles. Unplug unnecessaryaccessories plugged into the
cigarette lighter or theaccessory power outlet. Turnoff the radio and all lamps thatare not needed. This will avoidsparks and help save bothbatteries. And it could save theradio!
