Intrusion and Inclination
Sensors Disable Switch
It is recommended that the intrusion
and inclination sensors be
deactivated if pets are left in the
vehicle or the vehicle is being
transported.
With the vehicle off, press
oin
the front overhead console to turn
off the feature.
The indicator light will come on
momentarily, indicating that these
sensors have 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
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.
