Remote Central Locking (FZV)

Radio remote central locking is operational within a 10-meter radius of the car. The receiver, which has no antenna, is located inside the car at the front beneath the headlining.

The radio frequency signal (315 MHz) is converted by the receiver into a digital signal and forwarded to the BC1 for decoding. Security is through the use of the rolling code principle.

A maximum of 4 radio remote keys can be assigned to one vehicle. The key contains a single 3-volt battery that requires replacing after approximately two years. The cover is clipped to the main key housing and should be removed carefully to avoid damage to the plastic casing.

The functions of the radio remote key are:

• Lock: central arrest vehicle and arm anti-theft system (DWA).
• Unlock: release central arrest and disarm anti-theft system.
• Tailgate release: press and hold for > 4 seconds to open tailgate.
