• Remote control “Key” similar to that used on the E65, in the form of a "bitless" key
• An electronic fault and a mechanical fault must occur simultaneously
• No steering wheel lock mechanism in knee impact area
• The E90 can also be equipped with the Comfort Access option

Car Access System 2 (CAS2)
The CAS functions as the master controller and monitors the various driving or standstill
situations of the vehicle, using speed sensor data, and is therefore also the control mod-
ule that triggers/enables the unlocking (release) or locking action in the ELV.
