The Tire Pressure Monitoralerts you when asignificant reduction inpressure occurs in one ormore of the vehicle’s tiresby illuminating the low tirepressure warning light onthe instrument cluster.
The warning light will remain on until the tire pressure iscorrected. The proper tire pressures for your vehicleare listed on the Tire and Loading Information labellocated on the driver side center pillar (B pillar). SeeLoading the Vehicle on page 5-18.
You may notice during cooler conditions that the low tirepressure warning light will appear when the vehicle is firststarted and then turn off as you drive. This may be anearly indicator that your tire pressures are getting low andthe tires need to be inflated to the proper pressure.
Note:The Tire Pressure Monitor can alert you aboutlow tire pressure, but it does not replace normal monthlytire maintenance. It is the driver’s responsibility tomaintain correct tire pressures.
SeeTire Pressure Monitor System on page 6-57andTire Pressure Monitor Operation on page 6-58.

{WARNING:
Children who are up against, or very close to, any
airbag when it inflates can be seriously injured or
killed. Airbags plus lap-shoulder belts offer
protection for adults and older children, but not for
young children and infants. Neither the vehicle’s
safety belt system nor its airbag system is designed
for them. Young children and infants need the
protection that a child restraint system can provide.
Always secure children properly in your vehicle.
To read how, seeOlder Children on page 2-33or
Infants and Young Children on page 2-37.
There is an airbagreadiness light on theinstrument panel, whichshows the airbag symbol.
The system checks the airbag electrical system formalfunctions. The light tells you if there is an electricalproblem. SeeAirbag Readiness Light on page 4-50for more information.
Where Are the Airbags?
The driver frontal airbag is in the middle of thesteering wheel.
2-60
The passenger sensing system is designed to turn offthe right front passenger airbag and seat-mountedside impact airbag if:
•The right front passenger seat is unoccupied.
•The system determines that an infant is present in
a rear-facing infant seat.
•The system determines that a small child is present
in a child restraint.
•The system determines that a small child is present
in a booster seat.
•A right front passenger takes his/her weight off of
the seat for a period of time.
•The right front passenger seat is occupied by a
smaller person, such as a child who has outgrownchild restraints.
•Or, if there is a critical problem with the airbag
system or the passenger sensing system.
When the passenger sensing system has turned off theright front passenger frontal airbag and seat-mountedside impact airbag, the off indicator will light and stay litto remind you that the airbags are off. SeePassengerAirbag Status Indicator on page 4-51.
The passenger sensing system is designed to turn on(may inflate) the right front passenger frontal airbag andseat-mounted side impact airbag anytime the systemsenses that a person of adult size is sitting properly inthe right front passenger seat.
When the passenger sensing system has allowed theairbags to be enabled, the on indicator will light and staylit to remind you that the airbags are active.
For some children who have outgrown child restraintsand for very small adults, the passenger sensing systemmay or may not turn off the right front passenger frontalairbag and seat-mounted side impact airbag, dependingupon the person’s seating posture and body build.Everyone in the vehicle who has outgrown child restraintsshould wear a safety belt properly — whether or not thereis an airbag for that person.
{WARNING:
If the airbag readiness light ever comes on and
stays on, it means that something may be wrong
with the airbag system. To help avoid injury to
yourself or others, have the vehicle serviced right
away. SeeAirbag Readiness Light on page 4-50
for more information, including important safety
information.

Replacing Restraint System Parts
After a Crash
{WARNING:
A crash can damage the restraint systems in your
vehicle. A damaged restraint system may not
properly protect the person using it, resulting in
serious injury or even death in a crash. To help
make sure your restraint systems are working
properly after a crash, have them inspected and
any necessary replacements made as soon as
possible.
If the vehicle has been in a crash, do you need newsafety belts or LATCH system (if equipped) parts?
After a very minor crash, nothing may be necessary.But the safety belt assemblies that were used during anycrash may have been stressed or damaged. See yourdealer/retailer to have the safety belt assembliesinspected or replaced.
If the vehicle has the LATCH system and it was beingused during a crash, you may need new LATCH systemparts.
New parts and repairs may be necessary even if thesafety belt or LATCH system (if equipped), wasnot being used at the time of the crash.
If an airbag inflates, you will need to replace airbagsystem parts. See the part on the airbag system earlierin this section.
Have the safety belt pretensioners checked if thevehicle has been in a crash, if the airbag readiness lightstays on after the vehicle is started, or while you aredriving. SeeAirbag Readiness Light on page 4-50.
