{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.

KEYS, DOORS, AND WINDOWS 25
Inclination and Intrusion Sensor
Disable Switch
It is recommended that the intrusion
and inclination sensor be deactivated
if pets are left in the vehicle or the
vehicle is being transported. With the
vehicle turned off, press
oin the
front overhead console. The indicator
light will come on momentarily,
indicating that these sensors have
been disabled for the next alarm
system arming cycle.
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 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 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 0410.
Immobilizer Operation
This vehicle has a passive
theft-deterrent system.

26 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 turned
on or to ACC/ACCESSORY 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 the vehicle. Only a
correctly matched remote key will
start the 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.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 remote key appears to be
undamaged, try another remote key.
Or, you may try placing the remote
key in the backup location. See
Remote Keyless Entry (RKE) System
Operation
07.
If the ignition modes will not change
with the other remote key or in the
backup location, the vehicle needs
service. If the ignition does change
modes, the first remote key may be
faulty. See your dealer.
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 Keyless Entry
(RKE) System Operation 07.
Do not leave the remote key or device
that disarms or deactivates the
theft-deterrent system in the vehicle.
Exterior Mirrors
Convex Mirrors
{Warning
A convex mirror can make things,
like other vehicles, look farther
away than they really are. If you cut
too sharply into the right lane, you
could hit a vehicle on the right.
Check the inside mirror or 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.

This 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 light comes on and stays on, it
means that oil is not flowing through
the engine properly. The vehicle could
be low on oil and might have some
other system problem. See your dealer.
Low Fuel Warning Light
A Low Fuel Warning Light near the
fuel gauge comes on briefly when the
ignition is turned on as a check to
show it is working.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 Operation
0 25.
High-Beam On Light
This light comes on when the
high-beam headlamps are in use. See
Headlamp High/Low-Beam Changer
0134.
IntelliBeam Light
This light comes on when the
IntelliBeam system, if equipped, is
enabled. See Exterior Lamp Controls
0 132.
