# Service bulletin LI46.15\-P\-063353

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## NHTSA's summary

Complaint: Height adjustment of electric steering column adjustment jams in upper / lower adjustment position or it generates a cracking noise when exiting the upper /lower adjustment position \(e.g. for Easy Entry function\). Cause: Height adjustment runs into upper / lower limit stop and jams there or generates a breakaway cracking noise when exiting the jammed limit stop. Remedy: 1. Move fore/aft adjustment to the end position. 2. Release jamming of height adjustment by knocking with palm of hand onto top of steering wheel. At the same time, push adjusting switch \(downwards\). 3. Commission driver's seat control unit. While doing so, \- the control unit software is updated, if necessary \- the limit stops are cleared and normalized again \- and any renewed jamming is prevented 4. Once commissioning has been completed the vehicle can be handed over to the customer.
