WARNING LIGHTS AND CHIMES
Warning lights and gauges can alert you to a vehicle condition that may
become serious enough to cause expensive repairs. A warning light may
illuminate when a problem exists with one of your vehicle's functions.
Many lights will illuminate when you start your vehicle to make sure the
bulb works.If any light remains on after starting the vehicle, have
the respective system inspected immediately.

Check fuel cap
Illuminates when the fuel cap is not
installed correctly. Check the fuel
cap for proper installation. When
the fuel filler cap is properly
re-installed, the light(s) will turn off
after a period of normal driving. Continuing to operate the vehicle with
the check fuel cap light on, can activate theService Engine Soon/Check
Enginewarning light.
It may take a long period of time for the system to detect an
improperly installed fuel filler cap.
For more information, refer toFuel filler capin theMaintenance and
specificationschapter.
Brake system warning
²Standard instrument cluster
²Optional instrument cluster
Illuminates if the parking brake is
engaged. Also momentarily
illuminates at start up to ensure the
circuit is functional. If the brake
warning lamp does not illuminate at these times, or illuminates after
releasing the parking brake, seek service immediately. Refer toBrakesin
theDrivingchapter for more information.
Anti-lock brake system (ABS) (If equipped)
Momentarily illuminates at start up
to ensure the circuit is functional. If
the light does not illuminate,
remains on or continues to flash, the
ABS needs to be serviced (refer to
Brakesin theDrivingchapter for more information). With the ABS light
on, the ABS is disabled and normal braking is still functional.

Trunk ajar
If the trunk is not completely
closed, this light comes on when
you turn the ignition to ON. With
the ignition ON, this light will flash
five times and sound a tone for one
second, then the light remains on (if
the trunk is open).
Safety belt warning chime
Sounds to remind you to fasten your safety belts.
BeltMinder chime

Supplemental restraint system (SRS) warning chime
Sounds when a malfunction in the supplemental restraint system (front
or side airbags) has been detected. Have the supplemental restraint
system inspected immediately.
Headlamps on warning chime
Sounds when the headlamps or parking lamps are on, the key is removed
from the ignition and the driver's door is opened.
Key-in-ignition warning chime
Sounds when the key is left in the ignition and the driver's door is
opened.

²Restraints Control Module (RCM) with impact and safing sensors.
²Restraint system warning light and back-up tone.
²The electrical wiring for the air bags, crash sensor(s), safety belt
pretensioners, front safety belt usage sensors, driver seat position
sensor, passenger occupant classification sensor (if equipped), and
indicator lights.
How does the personal safety system work?
The Personal safety system can adapt the deployment strategy of your
vehicle's safety devices according to crash severity and occupant
conditions. A collection of crash and occupant sensors provides
information to the Restraints control module (RCM). During a crash, the
RCM activates the safety belt pretensioners and/or either one or both
stages of the dual-stage air bag supplemental restraints based on crash
severity and occupant conditions.
The fact that the pretensioners or air bags did not activate for both front
seat occupants in a collision does not mean that something is wrong with
the system. Rather, it means the Personal safety system determined the
accident conditions (crash severity, belt usage, etc.) were not
appropriate to activate these safety devices. Front air bags and
pretensioners are designed to activate only in frontal and near-frontal
collisions, not rollovers, side-impacts, or rear-impacts unless the collision
causes sufficient longitudinal deceleration.
Driver and passenger dual-stage air bag supplemental restraints
The dual-stage air bags offer the capability to tailor the level of air bag
inflation energy. A lower, less forceful energy level is provided for more
common, moderate-severity impacts. A higher energy level is used for
the most severe impacts. Refer toAir bag supplemental restraints
section in this chapter.
Front crash severity sensor
The front crash severity sensor enhances the ability to detect the
severity of an impact. Positioned up front, it provides valuable
information early in the crash event on the severity of the impact. This
allows your Personal safety system to distinguish between different levels
of crash severity and modify the deployment strategy of the dual-stage
air bags and safety belt pretensioners.

Front safety belt usage sensors
The front safety belt usage sensors detect whether or not the driver and
front outboard passenger safety belts are fastened. This information
allows your Personal safety system to tailor the air bag deployment and
safety belt pretensioner activation depending upon safety belt usage.
Refer toSafety beltsection in this chapter.
Front safety belt pretensioners
The safety belt pretensioners are designed to tighten the safety belts
firmly against the occupant's body during a collision. This maximizes the
effectiveness of the safety belts and helps properly position the occupant
relative to the air bag to improve protection. The safety belt
pretensioners can be either activated alone or, if the collision is of
sufficient severity, together with the air bags.
Front safety belt energy management retractors
The front safety belt energy management retractors allow webbing to be
pulled out of the retractor in a gradual and controlled manner in
response to the occupant's forward momentum. This helps reduce the
risk of force-related injuries to the occupant's chest by limiting the load
on the occupant. Refer toSafety beltsection in this chapter.
Determining if the Personal safety system is operational
The Personal safety system uses a warning light in the instrument cluster
or a back-up tone to indicate the condition of the system. Refer to the
Warning lightsection in theInstrument clusterchapter. Routine
maintenance of the Personal safety system is not required.
The Restraints control module (RCM) monitors its own internal circuits
and the circuits for the air bag supplemental restraints, crash sensor(s),
safety belt pretensioners, front safety belt buckle sensors, driver seat
position sensor, and passenger occupant classification sensor (if
equipped). In addition, the RCM also monitors the restraints warning
light in the instrument cluster. A difficulty with the system is indicated
by one or more of the following.
²The warning light will either flash or stay lit.
²The warning light will not illuminate immediately after ignition is
turned on.
²A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem and warning light are repaired.
