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.

Older children who have outgrownbooster seats should wear thevehicle’ssafetybelts.
The manufacturer instructions thatcome with the booster seat state theweight and height limitations for thatbooster. Use a booster seat with alap-shoulder belt until the childpasses the fit test below:
.Sit all the way back on the seat.Do the knees bend at the seatedge? If yes, continue. If no,return to the booster seat.
.Buckle the lap-shoulder belt.Does the shoulder belt rest onthe shoulder? If yes, continue.If no, try using the rear safetybelt comfort guide, if available.See“Rear Safety Belt ComfortGuides”underLap-Shoulder Belt048.Ifacomfortguideisnotavailable, or if the shoulder beltstill does not rest on theshoulder, then return to thebooster seat.

82 Seats and Restraints
Warning (Continued)
rear-facing child restraint would
be very close to the inflating
airbag. A child in a forward-facing
child restraint can be seriously
injured or killed if the front
outboard passenger airbag
inflates and the passenger seat is
in a forward position.
Even if the airbag switch has
turned off the front outboard
passenger frontal airbag, no
system is fail-safe. No one can
guarantee that an airbag will not
deploy under some unusual
circumstance, even though it is
turned off.
Secure rear-facing child restraints
in a rear seat, even if the airbag
is off. If you secure a
forward-facing child restraint in
the front outboard passenger
seat, always move the seat as far
back as it will go. It is better to
secure the child restraint in a
rear seat.
{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.
To h e l p a v o i d i n j u r y t o y o u r s e l f o r
others, have the vehicle serviced
right away. SeeAirbag Readiness
Light099for more information,
including important safety
information.
If the vehicle does not have a rearseat that will accommodate arear-facing child restraint, arear-facing child restraint should notbe installed in the vehicle, even ifthe airbag is off.
If the child restraint uses a toptether, seeLower Anchors andTe t h e r s f o r C h i l d r e n ( L AT C HSystem)073for top tether anchorlocations.
Do not secure a child seat in aposition without a top tether anchorif a national or local law requiresthat the top tether be anchored, or ifthe instructions that come with thechild restraint say that the top strapmust be anchored.
In Canada, the law requires thatforward-facing child restraints haveatoptether,andthatthetetherbeattached.
When using the lap-shoulder belt tosecure the child restraint in thisposition, follow the instructions thatcame with the child restraint and thefollowing instructions:
1. Move the seat as far back as itwill go before securing theforward-facing child restraint.Move the seat upward or theseatback to an upright position,if needed, to get a tightinstallation of the childrestraint.

level is within the operating range
and the oil pressure is still low,
have the vehicle serviced. Always

This gauge shows the enginecoolant temperature.
It also provides an indicator of howhard the vehicle is working. During amajority of the operation, the gaugewill read 100 °C (210 °F) or less.If the vehicle is pulling a load orgoing up hills, it is normal for thetemperature to fluctuate andapproach the 122 °C (250 °F) mark.If the gauge reaches the 125 °C(260 °F) mark, it indicates that thecooling system is working beyondits capacity.

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.
