The access and start authorisation system

The vehicle can be locked or unlocked and the engine can be started or switched off, without the active

deployment of the radio-wave remote control ignition key, by using the optional comfort features of the

access and start authorisation system.

The components and functions listed in the table are constituent parts of the access and start authorisa-

tion system.

Convenience electronics

Ignition key with radio-

wave remote control

Radio-wave remote control as before, the access and start authorisation relay

analyses the radio signals; central locking functions via the

central control unit for the convenience system; tailgate remote control

Electromechanical

steering column locking

(ELV)

Locking and unlocking of the steering column when inserting and removing the key

by the access and start authorisation relay, ELV is off-circuit as long as the key is

neither removed nor inserted, ignition can be activated only when the steering

column is unlocked

Switch for access and

start authorisation

Automatic resetting of the ignition key to the neutral position after switching on the

engine, electrical pull-out lock: each key mechanically fits into the switch for access

and start authorisation and can be rotated; ignition occurs only once the ignition

key has been identified by the access and start authorisation relay

Immobiliser III Immobiliser III as before, acting together with the switch for access and start

authorisation, the engine control unit and the ELV

Softstart Via the CAN data bus drive and the access and start authorisation relay; also for

prolonged stops in the starting position (terminal 50 on), in the switch for access

and start authorisation the starter is engaged only until the engine is running -

leading to improved starter protection and less noise

access and start authori-

sation components

Access and start authorisation relay: left footwell under the carpet

Switch for access and start authorisation: on the right of the steering wheel
