Warning!
G
Some jurisdictions prohibit the driver from
using a mobile telephone while driving.
Whether or not prohibited by law, for safety
reasons, the driver should not use the mo-
bile telephone while the vehicle is in motion.
Stop the vehicle in a safe location before
placing or answering a call.
If you nonetheless choose to use the mobile
phone while driving, please use the hands-
free feature and be sure to pay attention to
the traffic situation at all times. Use the mo-
bile phone only when road, weather and traf-
fic conditions permit. Otherwise, you may
not be able to observe traffic conditions and
could endanger yourself and others.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approxima-
tely 14 m) every second.
Warning!
G
Never operate radio transmitters equipped
with a built-in or attached antenna (i.e. with-
out being connected to an external antenna)
from inside the vehicle while the engine is
running. Doing so could lead to a malfunc-
tion of the vehicle’s electronic system, pos-
sibly resulting in an accident and/or
personal injury.i
Various mobile phone cradles can be in-
stalled in the front center armrest, see separate
installation instructions for the mobile phone
cradle. These mobile phone cradles can be ob-
tained from an authorized Mercedes-Benz Cen-
ter. For more information about telephone

356 Controls in detailLocking and unlockingSmartKey with KEYLESS-GO*
Vehicles equipped with KEYLESS-GO come
with two SmartKeys with KEYLESS-GO,
each with remote control and a removable
mechanical key.
The KEYLESS-GO function is integrated
into the SmartKey. On these vehicles, the
validity of the SmartKey with KEYLESS-GO
is checked every time you grasp an outside
door handle.
With the KEYLESS-GO function, you can
lock and unlock the vehicle without using
the remote control buttons on the
SmartKey and start the engine without in-
serting the SmartKey in the starter switch.If the SmartKey with KEYLESS-GO is valid,
your vehicle unlocks:

To prevent possible malfunction, avoid ex-
posing the SmartKey with KEYLESS-GO to high
levels of electromagnetic radiation.
Warning!
G
When leaving the vehicle, always take the
SmartKey with KEYLESS-GO* with you and
lock the vehicle. Do not leave children unat-
tended in the vehicle, or with access to an
unlocked vehicle. A child’s unsupervised ac-
cess to a vehicle could result in an accident
and/or serious personal injury.
Children could start the vehicle with a valid
SmartKey with KEYLESS-GO left in the
vehicle or with the KEYLESS-GO button on
the starter switch, or could release the
electronic parking brake, thereby putting
themselves and others in danger. Switch off
the engine and take the SmartKey with
KEYLESS-GO with you even if you are only
leaving the vehicle for a short while.

358 Controls in detailLocking and unlockingImportant notes on using KEYLESS-GO
You can also use the SmartKey with
KEYLESS-GO like a normal SmartKey
(page 352).
The starter switch is located 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 mobile
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.
In order to start the engine with the
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 366).
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

With the easy-entry/exit feature activated
the steering wheel tilts upwards and the
driver’s seat moves a few inches to the
rear when you:
remove the SmartKey from the starter
switch,
or
open the driver’s door with the
SmartKey in starter switch position 0

i
For safety reasons, the driver’s seat will not
return to its last set position with the easy-en-
try/exit feature activated if the system recogniz-
es the last set position as an extreme forward
position. Instead, the driver’s seat will remain at
or move to a factory-set maximum forward posi-
tion. To again fully return the driver’s seat to your
last set position or to memory position, adjust
the seat to the desired position or press and hold
the respective memory position button
(
page 386).
i
The last set driver’s seat and steering wheel
positions are stored when
the ignition is switched off (
page 365)
the position is stored in memory
(page 385)
i
If the current position for the steering wheel
is in the uppermost tilt position, the steering
wheel will no longer be able to move upward
when the easy-entry/exit feature is activated.
If the current seat position falls into a factory-set
position range and the system recognizes the
current seat position to be rearward enough for
easy entry and exit, the driver’s seat will not
move to the rear when the easy-entry/ exit fea-
ture is activated.
The adjustment procedure is briefly interrupted
when the engine is started.
Warning!
G
Let the system complete the adjustment
procedure before setting the vehicle in mo-
tion. All driver’s seat and steering wheel ad-
justments must be completed before setting
the vehicle in motion. Driving off with the
driver’s seat/steering wheel still adjusting
could cause the driver to lose control of the
vehicle.
