CAUTION: Once the steering column is removed
from the vehicle, the column is extremely
susceptible to damage. Dropping the column
assembly on its end could collapse the steering
shaft or loosen the slide block which maintains
column rigidity. Leaning on the column assembly
could cause the jacket to bend or deform. Any of the
above damage could impair the column's
collapsible design. If it is necessary to remove the
steering wheel, use only the specified steering
wheel puller. Under no conditions should the end of
the shaft be hammered upon, as hammering could
loosen the slide block which maintains column
rigidity.

Removal

1. Turn the steering wheel so that the vehicle's wheels

are pointing straight ahead.

2. Turn the ignition switch to “LOCK".

3. Disconnect the battery ground cable, and wait at

least 5 minutes.

WARNING: THE INFLATOR MODULE SHOULD
ALWAYS BE CARRIED WITH THE TRIM COVER
AWAY FROM YOUR BODY AND SHOULD ALWAYS
BE LAID ON A FLAT SURFACE WITH THE
URETHANE SIDE UP. THIS IS NECESSARY
BECAUSE FREE SPACE IS PROVIDED TO ALLOW
THE AIR CUSHION TO EXPAND IN THE UNLIKELY
EVENT OF ACCIDENTAL DEPLOYMENT.
OTHERWISE, PERSONAL INJURY MAY RESULT.

are pointing straight ahead.

2. Turn the ignition switch to “LOCK".

3. Disconnect the battery ground cable, and wait at

least 5 minutes.

4. Disconnect the yellow 2-way SRS connector located

under the steering column.

CAUTION: The wheels of the vehicle must be
straight ahead and the steering column in the
“LOCK" position before disconnecting the steering
wheel. Failure to do so will cause the coil assembly
to become uncentered which will cause damage to
the coil assembly.
