Important notes on using KEYLESS-GO

You can also use the SmartKey with
KEYLESS-GO like a normal SmartKey
(
page 70).
The starter switch is under the
KEYLESS-GO button. Pull the
KEYLESS-GO button out in order to ac-
cess the starter switch.

You can combine KEYLESS-GO func-
tions with normal SmartKey functions
(e.g. unlocking with KEYLESS-GO and
locking with button ‹).

Always carry the SmartKey with
KEYLESS-GO with you.

Never store the SmartKey with
KEYLESS-GO together with:

Electronic items such as a tele-
phone or another SmartKey with
KEYLESS-GO

Metallic objects such as coins or
metal foil
Doing so could impair the function of
the KEYLESS-GO system.

To lock or unlock the vehicle, the
SmartKey with KEYLESS-GO must be
located outside the vehicle within ap-
proximately 3 ft (1 m) of a door or the
trunk lid.

If the vehicle has been parked for more
than 72 hours, you must pull an outside
door handle in order to activate the
KEYLESS-GO function.

SmartKey with KEYLESS-GO:

The SmartKey with KEYLESS-GO
must be located in the vehicle.

The KEYLESS-GO start/stop button
must be inserted in the starter
switch (
page 84).

The brake pedal must be firmly de-
pressed. Do not depress the accel-
erator.

If the SmartKey with KEYLESS-GO is
positioned farther away from the vehi-
cle, the system may no longer recog-
nize the SmartKey with KEYLESS-GO.
The vehicle then cannot be locked or
the engine started via the KEYLESS-GO
system.

If the SmartKey with KEYLESS-GO is re-
moved from the vehicle (e.g. if passen-
ger exits the vehicle with the SmartKey
with KEYLESS-GO)

when pressing the KEYLESS-GO
start/stop button or trying to lock
the vehicle with the outside door
handle the message
Key not rec-
ognized
appears in the multifunc-
tion display

Use the mechanical key to unlock the driv-
er’s door (
page 424) and trunk
(
page 425).

Use the mechanical key to lock and trunk
(
page 272).

Have the vehicle batteries and their connec-
tions checked (
page 446).
If the SmartKey with KEYLESS-GO is malfunc-
tioning, contact Roadside Assistance or an
authorized Mercedes-Benz Center.
