WARNING: This page is about a different car, the 2004 Jeep Wrangler. However, it is still accessible from the selected car via links, so may be relevant.
WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, DISABLE THE AIRBAG SYSTEM BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE. SEE AIR BAG RESTRAINT SYSTEMS ARTICLE. THIS IS THE ONLY SURE WAY TO DISABLE THE AIRBAG SYSTEM. FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY.
  1. Disconnect and isolate the battery negative cable.
  2. Remove the steering column opening cover from the instrument panel. See INSTRUMENT CLUSTER article.

  5. Remove the upper and lower shrouds from the steering column.

  8. The SKIM mounting bracket features a clip that secures the SKIM to the inboard lower flange of the steering column jacket. Pull downward on the connector end of the SKIM mounting bracket to release this clip from the steering column jacket.
  9. Rotate the SKIM and its mounting bracket downwards and then to the side away from the steering column to slide the SKIM antenna ring from around the ignition switch lock cylinder housing. On models with a manual transmission, lift the multifunction switch upward off of the upper steering column housing far enough to extract the SKIM antenna from between the ignition key release button and the right multi-function switch housing.
  10. Remove the SKIM from the steering column.
