Important information about using
KEYLESS-GO
You can use the KEYLESS-GO key as a
R
conventional SmartKey.
You can combine KEYLESS-GO functions
R
with those of a conventional SmartKey, e.g.
you can open the vehicle with KEYLESS-GO
and close it with the & button.
Always carry your KEYLESS-GO key on your
R
person.
Never store the KEYLESS-GO key together
R
with:
electronic devices, such as a mobile
-
phone or other SmartKey
metal objects, such as coins or metal foil
-
Doing so may impair the function of
KEYLESS-GO.
To open or close the vehicle, the KEYLESS-
R
GO key should not be more than 3 ft (1 m)
from the door or trunk.
If the vehicle is parked for more than
R
72 hours, the KEYLESS-GO function is
deactivated. Pull an outer door handle and
switch on the ignition to reactivate the
KEYLESS-GO function.
If the KEYLESS-GO key is removed from the
R
vehicle, the system may not be able to
recognize the SmartKey anymore. The
vehicle can then no longer be locked or
started with KEYLESS-GO.
If the KEYLESS-GO key has been removed
R
from the vehicle, e.g. when another vehicle
occupant with a KEYLESS-GO key leaves
the vehicle:

again by:
pressing the Start/Stop button
-
inserting the KEYLESS-GO key into the
-
ignition lock while the vehicle is at a
standstill and the automatic
transmission is in park position P.
You may inadvertently unlock the vehicle if
R
the KEYLESS-GO key is less than 3 ft (1 m)
from the vehicle and:
an exterior door handle is hit by a jet of
-
water, or
you clean an exterior door handle
-
Please note that any vehicle occupant can
R
start the engine when there is a KEYLESS-
GO key in the vehicle.
Scenario 1: There is a KEYLESS-GO key in
the vehicle and a second one outside the
vehicle. If you leave the KEYLESS-GO key
in the vehicle when you leave and lock the
vehicle, no message appears in the
multifunction display.
Scenario 2: There is a KEYLESS-GO key in
the vehicle, but none outside the vehicle. If
you get out of the vehicle and attempt to
lock it, the
message appears in the multifunction
display. The vehicle is not then locked.
When starting the engine and whilst driving,
KEYLESS-GO also checks whether a valid
SmartKey is in the vehicle by periodically
establishing radio contact.
