CLOCK SPRING INSTALLATION

Align the mating marks of the clock spring and, after turning
the front wheels to the straight-ahead position, install the
clock spring to the column switch.

Mating Mark Alignment

Turn the clock spring clockwise fully, and then turn back it
approx. 3 4/5 turns counterclockwise to align the mating marks.

Caution
If the clock spring’s mating marks are not properly aligned,
the steering wheel may not be completely rotational during
a turn, or the flat cable within the clock spring may be
severed, obstructing normal operation of the SRS and
possibly leading to serious injury to the vehicle’s driver.

harness of the clock spring does not become caught
or tangled.
