2. AIRBAG MODEL INSPECTION
WARNING:
For airbag model inspection procedures, refer
to Supplemental Restraint System. [W200].>
D: ASSEMBLY
1) Insert combination switch to upper column
shaft, and install lower column cover with tilt lever
held in the lowered position. Then route ignition
key harness and combination switch harness
between column cover mounting bosses.
B4M0555
2) Fit upper column cover to lower column cover,
and tighten combination switch and column cover.
Tightening torque:
1.2
±0.2 N´m (0.12±0.02 kg-m, 0.9±0.1 ft-lb)
CAUTION:
Don't overtorque screw.
E: INSTALLATION
1) Insert end of steering shaft into toe board grom-
met.
2) Tighten steering shaft mounting bolts under
instrument panel.
Tightening torque:
25
±5 N´m (2.5±0.5 kg-m, 18.1±3.6 ft-lb)
3) Connect ignition and combination switch con-
nectors under instrument panel.
4) Connect airbag system connector at harness
spool.NOTE:
Make sure to apply double lock.
5) Install universal joint.
(1) Align bolt hole on the long yoke side of uni-
versal joint with the cutout at the serrated sec-
tion of shaft end, and insert universal joint.
(2) Align bolt hole on the short yoke side of
universal joint with the cutout at the serrated
section of gearbox assembly. Lower universal
joint completely.
(3) Temporarily tighten bolt on the short yoke
side. Raise universal joint to make sure the bolt
is properly passing through the cutout at the
serrated section.
(4) Tighten bolt on the long yoke side, then that
on the short yoke side.
Tightening torque:
24
±3 N´m (2.4±0.3 kg-m, 17.4±2.2 ft-lb)
CAUTION:
IMake sure that universal joint bolts is tight-
ened through notch in shaft serration.
IExcessively large tightening torque of uni-
versal joint bolts may lead to heavy steering
wheel operation.
Standard clearance between gearbox to DOJ:
Over 15 mm (0.59 in)
6) Align center of roll connector. (with airbag
model)

CAUTION:
Ensure that front wheels are set in straight-for-
ward direction.
7) Set steering wheel to neutral and install it onto
steering shaft.
