10.1 STEERING SYSTEM DESCRIPTION
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
IS CENTERED AND THE COLUMN LOCK IS ENGAGED. IFTHE

13.8.1 Seating, Description
The front seats are available in a range of materials consisting of sculptured fabric / leather, leather, sports cloth / leather, embossed leather / leather and autolux. Both seats are available as 'manual', ie manually adjustable with elec- tric rise and fall, manual height adjustment headrests, 'power', ie 12-way electric adjustment, 'power with memory', ie memory controlled, 12-way electric adjustment of seat, steering column and exterior rear view mirrors and 'heated',
ie with integral heating.
Front seats are based on a non
-handed, one-piece frame which includes cushion and squab frames and seat adjuster
mechanisms. The seat switchpacks (powerseats) are fitted to the outboard side of driver and passenger seats; on 'man- ual'seats, the seat height adjustment switch is similarly located. Seat control modules SCMs are contained within the
seat assemblies. The seats are secured through four mounting points to the vehicle floor.
Rear seats are of the bench type with
full width removable cushion and individual seat squabs.
Electrical components installed on the heel board below the rear passenger seat are protected
by two covers secured
by two locating brackets on the floor and by two latches on the cover. The latches are released by pushing down on
the two recesses in the top edge of the cover.
