hazard. If swallowed, internal burns
can occur, resulting in severe injury
or death. Seek medical attention
immediately if a battery is
swallowed.
{Warning
To avoid personal injury, do not
touch metal surfaces on the RKE
transmitter when it has been
exposed to extreme heat. These
surfaces can be hot to the touch at
temperatures above 59 °C (138 °F).
Caution
When replacing the battery, do not
touch any of the circuitry on the
transmitter. Static from your body
could damage the transmitter.
Caution
Always replace the battery with the
correct type. Replacing the battery
with an incorrect type could
potentially create a risk of battery
explosion. Dispose of used batteries
according to instructions and local
laws. Do not attempt to burn,
crush, or cut the used battery, and
avoid exposing the battery to
environments with extremely low
air pressures or high temperatures.
Replace the battery if the DIC displays

The Driver Information Center (DIC)
may display one of these messages:
.A message to service the steering
column lock indicates that an issue
has been detected with the column
lock feature and the vehicle should
be serviced.
.A message that the steering column
is locked indicates that the engine
is running, but the steering column
is still locked. It is normal for the
column to be locked during a
remote start, but the column should
unlock after the brake pedal is
pressed and the vehicle is started.
No message will display during a
remote start.
.A message that the steering wheel
must be turned and the vehicle
must be started again indicates that
the column lock mechanism is
bound, the column locking device
was unable to unlock the steering
column, and the vehicle did not
start. If this happens, immediately
turn the steering wheel from side to
side to unbind the column lock.
If this does not unlock the steering
column, turn the vehicle off and
open the driver door to reset thesystem. Then turn the vehicle on
and immediately turn the steering
wheel side to side for about
15 seconds. In some cases, it may
take significant force to unbind the
column.
To keep the steering column from
binding, straighten the front wheels
before turning off the vehicle.
Immobilizer
See Radio Frequency Statement 0406.
Immobilizer Operation
This vehicle has a passive
theft-deterrent system.
The system does not have to be
manually armed or disarmed.
The vehicle is automatically
immobilized when the vehicle is
turned off.
The immobilization system is
disarmed when the ignition is on or in
ACC/ACCESSORY and a valid
transmitter is present in the vehicle.
The security light, in the instrument
cluster, comes on if there is a problem
with arming or disarming the
theft-deterrent system.
The system has one or more RKE
transmitters matched to an
immobilizer control unit in your
vehicle. Only a correctly matched RKE
transmitter will start the vehicle.
If the transmitter is ever damaged,
you may not be able to start your
vehicle.
When trying to start the vehicle, the
security light may come on briefly
when the ignition is turned on.
If the engine does not start and the
security light stays on, there is a
problem with the system. Turn the
ignition off and try again.
If the vehicle will not change ignition
modes (ACC/ACCESSORY, on, off), and
the RKE transmitter appears to be

66 SEATS AND RESTRAINTS
{Warning
When an airbag inflates, there may
be dust in the air. This dust could
cause breathing problems for
people with a history of asthma or
other breathing trouble. To avoid
this, everyone in the vehicle should
get out as soon as it is safe to do
so. If you have breathing problems
but cannot get out of the vehicle
after an airbag inflates, then get
fresh air by opening a window or a
door. If you experience breathing
problems following an airbag
deployment, you should seek
medical attention.
The vehicle has a feature that may
automatically unlock the doors, turn
on the interior lamps and hazard
warning flashers, and shut off the fuel
system after the airbags inflate. The
feature may also activate, without
airbag inflation, after an event that
exceeds a predetermined threshold.
After turning the ignition off and then
on again, the fuel system will return
to normal operation; the doors can be locked, the interior lamps can be
turned off, and the hazard warning
flashers can be turned off using the
controls for those features. If any of
these systems are damaged in the
crash they may not operate as normal.
{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 front outboard
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 the
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
0 408 and
Event Data Recorders 0408.
.Let only qualified technicians work
on the airbag system. Improper
service can mean that an airbag
system will not work properly. See
your dealer for service.
Passenger Sensing System
The vehicle has a passenger sensing
system for the front outboard
passenger position. The passenger
airbag status indicator will light on
the overhead console when the vehicle
is started.
