Steering (11.00)
Steering Column (11.04)
Description
The steering column has reach and tilt functions. These let
the driver manually set the position of the steering column.
by using the reach / tilt lever that is on the underside of the
steering column.This is indepe ndent of the ignition switch
position .
The steering intermediate shaft has two parts. The lower
shaft is attached to both th e steering gear and the upper
shaft.
The Electronic Steering Column Lock (ESCL) is attached to
the upper casting of the steering column and has a locking
pin. The steering column is electrically unlocked when the
ignition key is installed and operated to position 2. The lock
engages when the ignition switch is removed and the
steering wheel is turned to the centre position.
