ID transmitter

Each vehicle is supplied with a purse key/spare key and two ID transmitters. The adapter for the spare key is located in the glove compartment.

NOTE: Up to eight ID transmitters can be used in conjunction with the Comfort Access function. Four ID transmitters can be used for personal profiles.

The ID transmitter has one button for locking and one for unlocking the vehicle. There is a separate button for unlocking the trunk. Pressing the trunk symbol button triggers automatic closing/opening of the trunk. Automatic closing requires the automatic trunk actuation option.

The ID transmitter contains a battery which lasts up to four years.

The mechanical key is located in the ID transmitter.

NOTE: The passenger airbag can also be deactivated/activated with the mechanical key.
