the column should unlockafter the brake pedal is
pressed and the vehicle is
started. No message will
display during a remote
start.

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
