CAUTION
Some models covered by this manual are equipped with a Supplemental Restraint System (SRS), which uses an air bag. Whenever working near any of the SRS components, such as the impact sensors, the air bag module, steering column and instrument panel, disable the SRS, as described in Section 6.

  1. Disconnect the negative battery cable. Remove the steering wheel.
  2.  
  3. Remove the trim panel on the lower left side.
  4.  
  5. Remove the steering column casing lower section.
  6.  
  7. Press in the retaining hooks on both sides and remove the switch.
