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.
