10.1.1 Steering Column Major Components
Integrated column assembly incorporating power, or manual, reach /tilt mechanism and lock.
Ignition switch.
Ignition interlock solenoid.
Key transponder coil.
Body attachment points.
Depending upon model, the steering column may be adjusted for
tilt and reach, either by electrical or manual means.
Power variants may be either automatically or manually adjusted and all types have the entry / exit feature.
10.1.2 Steering Column Operating Principle
Power Adjust: Two independent motor / gearbox assemblies provide infinite adjustment for reach and height within
approximate ranges of 35mm and
13O respectively. Adjustments may be automatically made in conjunction with the
seat memory facility or manually when the adjustment switch is used. It should be noted that selection of 'Off will
disable the automatic entry / exit mode.
Manual Adjust: The cable operated reach adjustment is infinite within a range of 35mm, with the desired position being
fixed
by a rack and wedge. Tilt variations are stepped at approximately 3O intervals with 6 positions being available,
the uppermost being unlatched.
From the uppermost position the column may be pulled down to engage the first detent without using the
tilt lever.
WARNING: MANUAL ADJUST ONLY: TO AVOID PERSONAL INJURY, COLUMN UPWARD TRAVEL SHOULD BE MAN- UALLY RESTRAINED TO CHECK UPWARD SPRING ASSISTANCE. THIS IS ESPECIALLY IMPORTANT IF
THE STEERING WHEEL HAS BEEN REMOVED FOR MAINTENANCE REASONS.
WARNING: ALL TYPES; DO NOT REMOVE THE STEERING COLUMN FROM THE VEHICLE WITH THE STEERING
WHEEL ATTACHED UNLESS THE STEERING
