Central locking buttons E369 to E372
(optional)
A button for locking the central locking
system is fitted in each door handle.
The central locking system can only be locked
if a key is recognised by an external aerial on
the same side of the vehicle as the key.
Exterior door handle touch
sensors G415 to G418 (optional)
The capacitive sensors are integrated into the
outer door handle and are actuated with DC
voltage. The entry and start authorisation
control unit evaluates the sensor current.
One capacitor plate each is integrated into the
handle and mount.
The finger recess acts as a dielectric. Insertion
of a medium between the capacitor plates
alters the capacitance and results in a brief
flow of current. This current is detected and
evaluated by the entry and start authorisation
control unit.
Entry and start authorisation aerials R134,
R135, R138, R155, R156 (optional)
A ferrite aerial is integrated into each outer
door handle for the transmission of signals by
the entry and start authorisation control unit
to the vehicle key. A further ferrite aerial is
located at the multimedia operating unit
E380.
Entry and start authorisation aerials R136,
R137, R139, R154, R166 (optional)
Air-core coil aerials for key recognition are
fitted at the rear of the passenger
compartment, in the luggage compartment
beneath the rear shelf and in the rear bumper.
