Radio reception factors
There are certain factors that may effect your radio reception.
•Distance/strength.The further an FM signal travels, the weaker it is.
The listenable range of the average FM station is approximately 40 km
(24 miles). This range can be affected by “signal modulation.” Signal
modulation is a process radio stations use to increase their
strength/volume relative to other stations.
•Terrain.Hills, mountains and tall buildings between your vehicle’s
antenna and the radio station signal can cause FM reception problems.
Static can be caused on AM stations by power lines, electric fences,
traffic lights and thunderstorms. Moving away from an interfering
structure (out of its “shadow”) returns your reception to normal.
•Station overload.Weak signals are sometimes captured by stronger
signals when you pass a broadcast tower. A stronger signal may
temporarily overtake a weaker signal and play while the weak station
frequency is displayed.
Principles of GPS (global positioning system) operation
Your system directs you based on information derived from global
positioning satellites, road maps stored on the DVD, sensors in your
vehicle and the desired destination. The system compiles all necessary
information to guide you to your selected destination. Space satellites
determine the vehicle’s current location and transmit position and time
signals to your car.
If the vehicle has been parked for a long period of time, the navigation
function may be temporarily unresponsive. The navigation system will
operate reliably again once GPS reception is available for a few minutes.
Limited GPS reception
System performance may be adversely affected if GPS reception is
interrupted or interference occurs over a distance of several miles. The
following are possible causes for GPS reception being interrupted. If the
vehicle is:
•in multi-story parking garages
•in tunnels and under bridges
•inside or in between buildings
•by forests or tree-lined avenues
•in heavy rain showers and thunderstorms
•in valleys and in mountainous regions

Accessory delay (if equipped)
With accessory delay, the window switches, radio, and moonroof may be
used for up to ten minutes after the ignition switch is turned to the OFF
position or until any door is opened.
MIRRORS
Automatic dimming inside rear view mirror (if equipped)
Your vehicle may be equipped with an inside rear view mirror which has
an auto-dimming function (available as an option on the outside driver’s
side mirror). The electronic day/night mirror will change from the normal
(high reflective) state to the non-glare (darkened) state when bright
lights (glare) reach the mirror. When the mirror detects bright light from
behind the vehicle, it will automatically adjust (darken) to minimize
glare.
The mirror will automatically return to the normal state whenever the
vehicle is placed in R (Reverse)(when the mirror is on) to ensure a
bright clear view when backing up.
Do not block the sensor on the backside of the mirror since this may
impair proper mirror performance.
Without Navigation System
The mirror automatically adjust
(darken) to minimize glare.

SAFETY RESTRAINTS
Personal Safety System
The Personal Safety System provides an improved overall level of frontal
crash protection to front seat occupants and is designed to help further
reduce the risk of airbag-related injuries. The system is able to analyze
different occupant conditions and crash severity before activating the
appropriate safety devices to help better protect a range of occupants in
a variety of frontal crash situations.
Your vehicle’s Personal Safety System consists of the following items:
•Driver and passenger dual-stage airbag supplemental restraints
•Driver and front passenger side airbags
•Front safety belts with pretensioners, energy management retractors,
and safety belt usage sensors
•Driver’s seat position sensor
•Front passenger sensing system
•Front crash severity sensor
•Restraints Control Module (RCM) with impact and safing sensors
•Restraint system warning light and back-up tone
•The electrical wiring for the airbags, crash sensor(s), safety belt
pretensioners, front safety belt usage sensors, driver seat position
sensor, 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 airbag supplemental restraints based on crash
severity and occupant conditions.
The fact that the pretensioners or airbags 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 airbags 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 airbag supplemental restraints
The dual-stage airbags offer the capability to tailor the level of airbag
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 toAirbag 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 airbags and safety belt pretensioners.
Driver’s seat position sensor
The driver’s seat position sensor allows your Personal Safety System to
tailor the deployment level of the driver dual-stage airbag based on seat
position. The system is designed to help protect smaller drivers sitting
close to the driver airbag by providing a lower airbag output level.

Front passenger sensing system
For airbags to do their job they must inflate with great force, and this
force can pose a potentially deadly risk to occupants that are very close
to the airbag when it begins to inflate. For some occupants, like infants
in rear-facing child seats, this occurs because they are initially sitting
very close to the airbag. For other occupants, this occurs when the
occupant is not properly restrained by seat belts or child safety seats and
they move forward during pre-crash braking. The most effective way to
reduce the risk of unnecessary injuries is to make sure all occupants are
properly restrained. Accident statistics suggest that children are much
safer when properly restrained in the rear seating positions than in the
front.
Air bags can kill or injure a child in a child seat.NEVERplace a
rear-facing child seat in front of an active air bag. If you must
use a forward-facing child seat in the front seat, move the seat all the
way back.
Always transport children 12 years old and under in the back
seat and always properly use appropriate child restraints.
The front passenger sensing system can automatically turn off the front
passenger front airbag when a rear facing child seat, a forward facing
child seat, or a booster seat is detected. Even with this technology,
parents areSTRONGLYencouraged to always properly restrain children
in the rear seat. The sensor also turns off the airbag when the passenger
seat is empty to prevent unnecessary replacement of the airbag(s) after
a collision.
When the front passenger seat is occupied and the sensing system has
turned off the passenger’s frontal airbag, the “pass airbag off” indicator
will light and stay lit to remind you that the front passenger frontal
airbag is off. SeeFront passenger sensing systemin the airbags section
of this chapter.
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 airbag 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 at the front outboard seating positions are
designed to tighten the safety belts firmly against the occupant’s body
during a frontal or near-frontal collision. This maximizes the effectiveness
of the safety belts and helps properly position the occupant relative to
the airbag to improve protection. The safety belt pretensioners can be
either activated alone or, if the collision is of sufficient severity, together
with the airbags.
Front safety belt energy management retractors
The front outboard 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 toEnergy management feature
section 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 theWarning 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 airbag supplemental restraints, crash sensor(s),
safety belt pretensioners, front safety belt buckle sensors, and the driver
seat position sensor. 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.
•The warning light will either flash or stay lit.
•The warning light will not illuminate immediately after ignition is
turned on.
•A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem and warning light are repaired.
If any of these things happen, even intermittently, have the Personal
Safety System serviced at your dealership or by a qualified technician
immediately. Unless serviced, the system may not function properly in
the event of a collision.
Safety restraints precautions
Always drive and ride with your seatback upright and the lap
belt snug and low across the hips.

BeltMinder
The BeltMinderfeature is a supplemental warning to the safety belt
warning function. This feature provides additional reminders by
intermittently sounding a chime and illuminating the safety belt warning
lamp in the instrument cluster when the driver’s and front passenger’s
safety belt is unbuckled.
The BeltMinderfeature uses information from the passenger occupant
classification sensor to determine if a front seat passenger is present and
therefore potentially in need of a warning. To avoid activating the
BeltMinderfeature for objects placed in the front passenger seat,
warnings will only be given to large front seat occupants as determined
by the passenger occupant classification sensor.
Both the driver’s and passenger’s safety belt usages are monitored and
either may activate the BeltMinderfeature. The warnings are the same
for the driver and the front passenger. If the BeltMinderwarnings have
expired (warnings for approximately 5 minutes) for one occupant (driver
or front passenger), the other occupant can still activate the
BeltMinderfeature.

Children and airbags
Children must always be properly
restrained. Accident statistics
suggest that children are safer when
properly restrained in the rear
seating positions than in the front
seating position. Failure to follow
these instructions may increase the
risk of injury in a collision.
Airbags can kill or injure a
child in a child seat.
NEVERplace a rear-facing child
seat in front of an active airbag. If
you must use a forward-facing
child seat in the front seat, move
the seat all the way back.
How does the air bag supplemental restraint system work?
The air bag SRS is designed to
activate when the vehicle sustains
longitudinal deceleration sufficient
to cause the sensors to close an
electrical circuit that initiates air
bag inflation.
The fact that the air bags did not
inflate in a collision does not mean
that something is wrong with the
system. Rather, it means the forces
were not of the type sufficient to
cause activation. Driver and passenger airbags are designed to inflate in
frontal and near-frontal collisions, not rollover, side-impact, or
rear-impacts unless the collision causes sufficient longitudinal
deceleration.

The air bags inflate and deflate
rapidly upon activation. After air bag
deployment, it is normal to notice a
smoke-like, powdery residue or
smell the burnt propellant. This may
consist of cornstarch, talcum
powder (to lubricate the bag) or
sodium compounds (e.g., baking
soda) that result from the
combustion process that inflates the
air bag. Small amounts of sodium
hydroxide may be present which
may irritate the skin and eyes, but
none of the residue is toxic.
While the system is designed to help
reduce serious injuries, contact with
a deploying air bag may also cause abrasions, swelling or temporary
hearing loss. Because air bags must inflate rapidly and with considerable
force, there is the risk of death or serious injuries such as fractures,
facial and eye injuries or internal injuries, particularly to occupants who
are not properly restrained or are otherwise out of position at the time
of air bag deployment. Thus, it is extremely important that occupants be
properly restrained as far away from the air bag module as possible while
maintaining vehicle control.
The SRS consists of the following items:
•Driver and passenger air bag modules (which include the inflators and
air bags)
•Front passenger sensing system
•Driver and passenger side air bags (if equipped)
•One or more impact and safing sensors
•A readiness light and tone
•A diagnostic module
•The electrical wiring which connects the components
The diagnostic module monitors its own internal circuits as well as the
supplemental air bag electrical system wiring (including the impact
sensors), the system wiring, the air bag system readiness light, the air
bag back up power and the air bag ignitors.

Several air bag system components get hot after inflation. Do not
touch them after inflation.
If the air bag has deployed,the air bag will not function
again and must be replaced immediately.If the air bag is not
replaced, the unrepaired area will increase the risk of injury in a
collision.
If the safety belt pretensioners deploy in an accident, they will
not function again ( belt will not extract or retract) and must be
replaced immediately. Failure to replace the retractor assemblies will
increase the risk of injury.
Front passenger sensing system
The front passenger sensing system will turn off the front passenger’s
frontal air bag under certain conditions. The driver’s airbag is not part of
the front passenger sensing system. The front passenger sensing system
works with sensors that are part of the front passenger’s seat and safety
belt. The sensors are designed to detect the presence of a
properly-seated occupant and determine if the front passenger’s frontal
airbag should be enabled (may inflate) or not.
The front passenger sensing system is designed to meet the regulatory
requirements of Federal Motor Vehicle Safety Standard (FMVSS) 208
and is designed to turn off the front passenger’s frontal airbag if:
•the front passenger seat is unoccupied, or has small/medium objects in
the front seat,
•the system determines that an infant is present in a rear-facing infant
seat that is installed according to the manufacturer’s instructions,
•the system determines that a small child is present in a forward-facing
child restraint that is installed according to the manufacturer’s
instructions,
•the system determines that a small child is present in a booster seat,
•a front passenger takes his/her weight off of the seat for a period of
time,
•A smaller person, such as a child who has outgrown child restraints,
or a small adult occupies the front passenger seat.
