Mercedes-Benz GL-Class: Changing the settings of the lockingsystem
You can change the setting of the locking system in such a way that only the driver's door and the fuel filler flap are unlocked. This is useful if you frequently travel on your own.

down the 
buttons
simultaneously for approximately six
seconds until the battery check lamp flashes twice.
If the setting of the locking system is
changed within the signal range of the
vehicle, pressing the 
button
locks or unlocks the vehicle.
The SmartKey now functions as follows:
► To unlock the driver's door: press the
button once.
► To unlock centrally: press the
button twice.
► To lock centrally: press the
button.
The KEYLESS-GO function is changed as follows:
► To unlock the driver's door: touch the
inner surface of the door handle on the
driver's door
► To unlock centrally: touch the inner
surface of the door handle on the frontpassenger
door or the rear door.
► To lock centrally: press the locking
button
on one of the door handles.
Important notes on the use of KEYLESSGO
• The KEYLESS-GO key can be used like a
conventional key.
• You can combine KEYLESS-GO functions
with those of a conventional key, e.g.
unlock with KEYLESS-GO and lock with the
& button.
