Cars equipped with the "hands-free" system have presence sensors and body element opening antennas for card recognition:

opening antenna in the outer handle of each door,
opening antenna in the rear bumper,
presence sensor in the outer handle of each door.

Fig. 7.44. Door opening antenna placement diagram: 1 – opening antennas located in the outer door handles; 2 – opening antenna located in the rear bumper; 3 – engine start antennas

Note: The engine start antennas have no effect on unlocking the vehicle. In contrast, it is not possible to lock the vehicle using the "lock" switches located on the outside handles if the card is in the engine start zone.

Note: Motion sensors are built into presence sensors.

Removal antennas

For hands-free operation, the outer door handles are equipped with:

presence sensors to recognize the user's hand in combination with a reflector mounted on the handle;
with the lock button;
opening antenna built into the handle (Fig. 7.45).

Note: Only vehicles equipped with the hands-free system have a lock switch.

Note: If the car has not been used for approximately 72 hours, the presence sensors are switched off. In this case, the unlocking command is detected by the handle movement sensor. The presence sensor and the handle movement sensor are assembled.
