Chevrolet Silverado: Vehicle Security / 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.
The indicator light, on the instrument panel near the windshield, indicates the
status of the system.
Off : Alarm system is disarmed.
On Solid : Vehicle is secured during the delay to arm the system...
