INSTALLATION
NOTICE:

Never use SRS parts from another vehicle. When re-
placing parts, replace them with new ones.

Never reuse the seat position sensor assembly in-
volved in a collision when the airbag has deployed.

If the seat position sensor assembly center has been
dropped, or there are any cracks, dents or other de-
fects in the case, bracket or connector, replace it with
a new one.

When installing the seat position sensor assembly
center, be careful that the SRS wiring does not inter-
fere with other parts and that it is not pinched be-
tween other parts.

After installing, shake the seat position sensor as-
sembly to check that there is no looseness.
1. INSTALL SEAT POSITION SENSOR ASSEMBLY
(a) Using a feeler gauge 1 mm (0.039 in.), install the seat
position sensor assembly.
HINT:
Be sure that a clearance between the seat position sensor as-
sembly and the seat rail is between 0.6 mm (0.023 in.) and 2 mm
(0.079 in.).
(b) Using a torx
) socket wrench, tighten the torx) screw to
install the seat position sensor assembly.
Torque: 8.0 N´m (82 kgf´cm, 71 in.´lbf)
(c) Make sure that a clearance between the seat position
sensor assembly and the seat rail is between 0.6 mm
(0.023 in.) and 2 mm (0.079 in.).
(d) Connect the connector to the seat position sensor assem-
bly.
2. INSTALL SEAT POSITION SENSOR ASSEMBLY PRO-
TECTOR
Install the seat position sensor assembly protector to the seat
position sensor assembly.
