mechanical key.
The functions of the KEYLESS-GO-card (1) are identical
to those of the electronic key. Carrying the card with
you permits the use of the vehicle.The validity of the KEYLESS-GO-card is checked every
time when grasping a door handle or pushing the trunk
lid release. Once the KEYLESS-GO-card is recognized
outside the vehicle, the doors, trunk lid and fuel filler
flap are unlocked, depending on the selected mode
(global or selective unlocking mode, see page 41).

so that they are always handy. Never leave the electronic
key or a KEYLESS-GO-card in the vehicle.
