GM has built into these vehicles a security device that will lock out
the steering wheel to prevent theft when car is not in use. This locking pin
mechanism is attached to the 4+3 shifter . Since it is not possible to attach this
cable to the ROD shifter , we strongly recommend that you remove the pin or
override this device for your own safety . If this procedure is not done, the
steering wheel will lock out.
