Immobilizer Operation
This vehicle has PASS-Key®III+
(Personalized Automotive Security
System) theft-deterrent system.
PASS-Key
®III+ is a passive
theft-deterrent system.
The system is automatically armed
when the key is removed from the
ignition.
The system is automatically
disarmed when the key is turned
to ON/RUN, ACC/ACCESSORY
or START from the LOCK/OFF
position.
You do not have to manually arm or
disarm the system. The security light comes on if
there is a problem with arming
or disarming the theft-deterrent
system.
When the PASS-Key
®III+ system
senses an incorrect key, the vehicle
does not start. Anyone using a
trial-and-error method to start the
vehicle will be discouraged because
of the high number of electrical key
codes.
If the engine does not start and
the security light on the instrument
panel comes on when trying to start
the vehicle, there may be a problem
with your theft-deterrent system.
Turn the ignition off and try again.
If the engine still does not start,
and the key appears to be
undamaged, try another ignition
key and check the fuses. See Fuses
and Circuit Breakers on page 10‑32
for additional information. If the
engine still does not start with the
other key, the vehicle needs service.
If the vehicle does start, the first key
may be faulty. See your dealer who can service the PASS-Key
®III+
to have a new key made. In an
emergency, contact Roadside
Assistance. See Roadside
Assistance Program (U.S. and
Canada) on page 13‑8 orRoadside
Assistance Program (Mexico) on
page 13‑10.
It is possible for the PASS-Key
®III+
decoder to learn the transponder
value of a new or replacement key.
Up to 10 keys may be programmed
to the vehicle. The following
procedure is for programming
additional keys only. If all the
currently programmed keys are
lost or do not operate, you must
see your dealer or a locksmith who
can service PASS-Key
®III+ to have
keys made and programmed to the
system.
See your dealer or a locksmith who
can service PASS-Key
®III+ to get a
new key blank that is cut exactly as
the ignition key that operates the
system.

glance over your shoulder before
changing lanes.
The passenger side mirror is convex
shaped. A convex mirror's surface is
curved so more can be seen from
the driver seat.

3-40 Seats and Restraints
You can lock the doors, turn off the
interior lamps and hazard warning
flashers by using the controls for
those features.
{WARNING
A crash severe enough to inflate
the airbags may have also
damaged important functions
in the vehicle, such as the fuel
system, brake and steering
systems, etc. Even if the vehicle
appears to be drivable after a
moderate crash, there may be
concealed damage that could
make it difficult to safely operate
the vehicle.
Use caution if you should attempt
to restart the engine after a crash
has occurred.In many crashes severe enough
to inflate the airbag, windshields
are broken by vehicle deformation.
Additional windshield breakage
may also occur from the right front
passenger airbag..Airbags are designed to inflate
only once. After an airbag
inflates, you will need some
new parts for the airbag system.
If you do not get them, the
airbag system will not be there
to help protect you in another
crash. A new system will include
airbag modules and possibly
other parts. The service manual
for your vehicle covers the need
to replace other parts.
.The vehicle has a crash sensing
and diagnostic module which
records information after a
crash. See
Vehicle Data
Recording and Privacy on
page 13‑18 andEvent Data
Recorders on page 13‑18.
.Let only qualified technicians
work on the airbag systems.
Improper service can mean that
an airbag system will not work
properly. See your dealer for
service.

Seats and Restraints 3-43
For some children, including
children in child restraints, and for
very small adults, the passenger
sensing system may or may not
turn off the right front passenger
frontal airbag, depending upon
the person’s seating posture
and body build. Everyone in the
vehicle who has outgrown child
restraints should wear a safety
belt properly —whether or not
there is 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. See Airbag Readiness
Light on page 5‑15 for more
information, including important
safety information.
If the On Indicator is Lit for a
Child Restraint
If a child restraint has been installed
and the on indicator is lit:
1. Turn the vehicle off.
2. Remove the child restraint from the vehicle.
3. Remove any additional items from the seat such as blankets,
cushions, seat covers, seat
heaters, or seat massagers.
4. Reinstall the child restraint following the directions
provided by the child restraint
manufacturer and refer to
Securing Child Restraints (Rear
Seat) on page 3‑65 orSecuring
Child Restraints (Right Front
Passenger Seat) on page 3‑67. 5. If, after reinstalling the child
restraint and restarting the
vehicle, the on indicator is
still lit, turn the vehicle off.
Then slightly recline the vehicle
seatback and adjust the seat
cushion, if adjustable, to make
sure that the vehicle seatback
is not pushing the child restraint
into the seat cushion.
Also make sure the child
restraint is not trapped under
the vehicle head restraint.
If this happens, adjust the head
restraint. See Head Restraints
on page 3‑2.
6. Restart the vehicle.
The passenger sensing system
may or may not turn off the
airbag for a child in a child
restraint depending upon the
child’s seating posture and body
build. It is better to secure the
child restraint in a rear seat.

Seats and Restraints 3-45
A wet seat can affect the
performance of the passenger
sensing system. Here is how:
.The passenger sensing system
may turn off the passenger
airbag when liquid is soaked
into the seat. If this happens,
the off indicator will be lit, and
the airbag readiness light on the
instrument panel will also be lit.
.Liquid pooled on the seat that
has not soaked in may make it
more likely that the passenger
sensing system will enable (turn
on) the passenger airbag while a
child restraint or child occupant
is on the seat. If the passenger
airbag is turned on, the on
indicator will be lit.
If the passenger seat gets wet, dry
the seat immediately. If the airbag
readiness light is lit, do not install
a child restraint or allow anyone
to occupy the seat. See Airbag
Readiness Light on page 5‑15
for important safety information. The on indicator may be lit if
an object, such as a briefcase,
handbag, grocery bag, laptop or
other electronic device, is put on
an unoccupied seat. If this is not
desired remove the object from
the seat.
{WARNING
Stowing of articles under the
passenger seat or between the
passenger seat cushion and
seatback may interfere with the
proper operation of the passenger
sensing system.
Servicing the
Airbag-Equipped Vehicle
Airbags affect how the vehicle
should be serviced. There are
parts of the airbag system in
several places around the vehicle.
Your dealer and the service manual
have information about servicing
the vehicle and the airbag system.
To purchase a service manual,
see
Service Publications Ordering
Information on page 13‑15.
{WARNING
For up to 10 seconds after the
ignition 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.
