The KEYLESS-GO-card (1) does not have a removable
mechanical key.
The functions of the KEYLESS-GO-card (1) are identical
to those of the electronic main 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 43).
Starter switch KEYLESS-GO, see page 224.
Starting and turning off the engine with KEYLESS-GO,
see page 227 and page 228.
Note:
In the case of a malfunction in the KEYLESS-GO-system,
we recommend that you carry the electronic key plus
mechanical key with you and keep them in a safe place
so that they are always handy. Never leave the electronic
key or a KEYLESS-GO-card in the vehicle.
Obtaining replacement keys
Your vehicle is equipped with a theft deterrent locking
system requiring a special key manufacturing process.
For security reasons, replacement keys or the KEYLESS-
GO-card can only be obtained from your authorized
Mercedes-Benz Center.

Notes:
The automatic closing process is interrupted if the
trunk lid is pushed against an object. The trunk lid will
reverse slightly and stop. In its final closing stage the
hydraulic power closing assist mechanism releases the
trunk lid which then drops into the lock by its own
weight. Now the trunk lid will stop but not reverse
slightly.
Investigate and correct the cause of interruption.
Now press trunk lid close button (2) again to close the
trunk lid.In case of a malfunction the trunk lid can be opened and
closed manually.
To open, unlock trunk lid with the mechanical key and
open lid by hand, see page 53.
To close, lower trunk lid with hands placed flat on trunk
lid. Please remember to keep your fingers out of the
space between the lid and the vehicle.
Vehicles with KEYLESS-GO:
To prevent a possible inadvertent lockout, the trunk lid
will open automatically if a KEYLESS-GO-card is
recognized in the area of the rear shelf or inside the
trunk.
Wa r n i n g !
To prevent possible personal injury, always keep
hands and fingers away from the trunk opening
when closing the trunk lid. Be especially careful
when small children are around.Always be sure persons who might get injured are
away from the trunk area when you operate the
trunk lid closing button located on the vehicle door.To interrupt the hydraulic power closing assist
mechanism press trunk lid close button (2) inside
the trunk lid, push in trunk lid lock, or press
buttonŠ on the electronic main key.
