- pulling any door handle
(global or selective opening).
- pulling the rear-end door handle
(only rear-end door is opened).
Lock
The vehicle can be locked by:
- Actuation of left front door handle switch (S17/19), left rear door handle switch (S17/20), right rear door handle switch (S17/21) or right rear door handle switch (S17/22) on outer door handle.
- actuation of rear-end door Keyless Go button (S62/21) on rear-end door
The standard central locking (CL) remote control function is maintained parallel to the Keyless Go (KG) functions.

Locating areas of transmitter key
In the following areas, the transmitter key is located and checked for validity when the system is activated
Vehicle surroundings
- Outer range (A) is covered by the left rear door Keyless Go antenna (A2/39).
- Outer range (B) is covered by the right rear door Keyless Go antenna (A2/41).
- Outer range (C) is covered by the trunk Keyless Go antenna (A2/35).
Passenger compartment
- The inner area of vehicle (D) is covered by the Keyless Go cockpit antenna (A2/60) and the Keyless Go interior antenna (A2/61)

Sequence of position determination
The remote control requests a message from the antennas in a fixed sequence when the Keyless Go system (KG) is activated. From these messages, the transmitter key can determine its position in relation to the vehicle (different signal amplitudes) and can transmit it to the Keyless Go (N69/5) control unit via the roof antenna module (A2/93).
