{Warning
Leaving children in a vehicle
with a remote key is
dangerous and children or
others could be seriously
injured or killed. They could
operate the power windows
or other controls or make
the vehicle move. The
windows will function with
the remote key in the
vehicle, and children or
others could be caught in
the path of a closing
window. Do not leave
children in a vehicle with a
remote key.

Inclination and Intrusion
Sensors Disable Switch
It is recommended that the
inclination and intrusion
sensors be deactivated if pets
are left in the vehicle or if the
vehicle is being transported.
With the vehicle turned off,
press
oin the overhead
console. The indicator light will
come on momentarily,
indicating that the sensor has
been disabled until the next
time the alarm system is
armed.
Steering Column Lock
If equipped, the steering
column lock is a
theft-deterrent device. This
feature locks the steering
column when the vehicle is
turned off and the driver door
is opened, or when the driver
door is opened and then the
vehicle is turned off. The
steering column unlocks when
the vehicle is turned on. 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 thevehicle 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 the
system. 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 0452.
Immobilizer Operation
This vehicle has a passive
theft-deterrent system.

36 Keys, Doors, and Windows
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 accessory mode and a
valid remote key 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
remote keys matched to an
immobilizer control unit in your
vehicle. Only a correctly
matched remote key will startthe vehicle. If the remote key
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 (accessory
mode, on, off), and the remote
key appears to be undamaged,
try another remote key. Or,
you may try placing the
remote key in the remote key
pocket located in the center
console. See Remote Key
Operation
09.
If the ignition mode will not
change with the other remote
key or in the remote key
pocket, your vehicle needs
service. If the ignition does
change modes, the first
remote key may be faulty. See your dealer who can service
the theft-deterrent system
and have a new remote key
programmed to the vehicle.
It is possible for the
immobilizer system to learn
new or replacement remote
keys. Up to eight remote keys
can be programmed for the
vehicle. To program additional
remote keys, see
“Programming Remote Keys to
the Vehicle”
under Remote
Key Operation 09.
Do not leave the remote key
or device that disarms or
deactivates the
theft-deterrent system in the
vehicle.

It also comes on when the fuel
gauge indicator nears empty.
The light turns off when fuel is
added. If it does not, have the
vehicle serviced.
Security Light
The security light should come
on briefly as the engine is
started. If it does not come on,
have the vehicle serviced by
your dealer. If the system is
working normally, the indicator
light turns off.
If the light stays on and the
engine does not start, there
could be a problem with the
theft-deterrent system. See
Immobilizer Operation035.

This light comes on when the
high-beam headlamps are in
use. See Headlamp High/
Low-Beam Changer 0153.
IntelliBeam Light
This light comes on when the
IntelliBeam system,
if equipped, is enabled. See
Exterior Lamp Controls 0151.
Lamps On Reminder
This light comes on when the
exterior lamps are in use,
except when only the Daytime
Running Lamps (DRL) are
active. See Exterior Lamp
Controls 0151.
Cruise Control Light
The cruise control light is
white when the cruise control
is on and ready, and turns
green when the cruise control
is set and active.
See Cruise Control 0275.
