Instrument Cluster: Removal
- Fold trunk cover upward and remove battery negative cable. Disable air bag system. See AIR BAG RESTRAINT SYSTEMS - C, CLK & SLK CLASS article.
- Remove 2 bolts from back of steering wheel. Hold driver-side air bag module when removing last bolt. Remove driver-side air bag module from steering wheel enough to access driver-side air bag module squib connector. Disconnect driver-side air bag module squib connector. Disconnect horn connector, if necessary. Remove module from vehicle. Place module away from work area with pad facing up.
- If vehicle has telescoping steering column, pull steering wheel completely out and lock into position. If vehicle does not have telescoping steering column, remove steering wheel. Ensure front wheels are in straight-ahead position. Allow steering lock to engage. Mark steering wheel-to-shaft position to aid in reassembly. Remove steering wheel hub nut. Pull steering wheel off by hand or steering wheel puller, if necessary. When removing steering wheel, use extreme care not to break carbon contacts mounted to top of steering column.
- To remove instrument cluster on all vehicles, insert 2 Removal Hooks (140-589-02-33-00), with hooks facing down, between instrument panel and sides of instrument cluster. See Fig 1
. Turn removal hook handles 90 degrees. Carefully pull both hook handles outward to engage hooks in recesses in rear of cluster.
- Holding each hook at about 120 degree angle away from center of instrument cluster, alternately pull each side of instrument cluster out about .2" (5 mm) at a time. Do not pull on both hooks at the same time. See Fig 1
. Unplug wiring connectors and remove instrument cluster.
