- with CODE (889) Keyless Go


Keyless Go, general
The Keyless Go system allows access to the vehicle and starting the vehicle engine without using the transmitter key (A8/1). It is sufficient to carry the transmitter key.

Operation of the central locking (CL) via the transmitter key remains possible parallel to the Keyless Go functions.

The Keyless Go system comprises the following subfunctions:
^ Function sequence for position definition of transmitter key

Further partial functions are described in separate documents:
^ Locking/unlocking, function
^ Engine start-stop, function

The anti-theft alarm system (ATA) (with code (551) Anti-theft alarm system (ATA)) functions in the same manner as when locking/unlocking the CL with the transmitter key.

Function sequence for position definition of transmitter key
A position determination of the transmitter key is required for the individual functions. When the
- Trunk KEYLESS GO antenna (A2/35),
- Left rear door KEYLESS GO antenna (A2/39),
- Right rear door KEYLESS GO antenna A2/41),
- KEYLESS GO cockpit antenna (A2/60) and
- interior Keyless Go antenna (A2/61)
are activated by the Keyless Go system, the transmitter key can determine the area (A, B, C or D) in which it is located.







The determined position is transmitted by the transmitter key via radio signal. The roof antenna module (A2/93) edits the signal and relays it to the KEYLESS GO control unit (N69/5).
