34 Getting startedThe “Getting started” section provides an
overview of the vehicle’s most basic func-
tions. First-time Mercedes-Benz owners
should pay special attention to the infor-
mation given here.
If you are already familiar with the basic
functions described here, the “Controls in
detail” section will provide you with further
information. The corresponding page refer-
ences are located at the end of each seg-
ment.Unlocking

G
When leaving the vehicle, always remove the
SmartKey from the starter switch, take it
with you, and lock the vehicle. Do not leave
children unattended in the vehicle, or with
access to an unlocked vehicle. Unsuper-
vised use of vehicle equipment may cause
an accident and/or serious personal injury.iOpening a door causes the windows on
that side of the car to open slightly.
They will return to the up-position when
the door is closed.
35 Getting started
Unlocking
Unlocking with KEYLESS-GO*
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.
The function of the SmartKey overrules the
KEYLESS-GO function.
Grasp an outside door handle.
All turn signal lamps flash once. The
locking knobs on the doors move up.
The anti-theft alarm system is dis-
armed.
The electro-hydraulic brake system is
activated.If the SmartKey with KEYLESS-GO is inside
the vehicle, pressing the KEYLESS-GO
start/stop button on the gear selector le-
ver corresponds to turning the SmartKey
to the various starter switch positions
(
page 37).
For more information, see “SmartKey with
KEYLESS-GO*” (
page 100).
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. Unsupervised use of vehi-
cle equipment may cause an accident
and/or serious personal injury.
iTo unlock the vehicle, the SmartKey
with KEYLESS-GO must be outside the
vehicle, no further than approx. 3 feet
(1 meter) away from the door. iIf 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.
iOpening a door causes the windows on
that side of the car to open slightly.
They will return to the up-position when
the door is closed.
89 Safety and Security
Driving safety systems
The electro-hydraulic brake system is auto-
matically activated when you
unlock the vehicle with the SmartKey
or the SmartKey with KEYLESS-GO*
open the driver’s or passenger door
turn the SmartKey in the starter switch
to position1
in vehicles with KEYLESS-GO*, press
the start/stop button on the gear se-
lector lever once
depress the brake pedal
release the parking brake
iIf the electro-hydraulic brake system is
activated as the brake pedal is first de-
pressed, you may feel a reduced pedal
resistance and longer pedal travel than
normal. When releasing the pedal, you
may also feel the brake pedal pulsate
and you may hear a sound which is
caused by the activation of the elec-
tro-hydraulic brake system pump. This
is normal and not an indication of a
malfunction. Pedal travel returns to
normal when you release the brake
pedal and the sound soon ceases.
If you experience the above while driv-
ing and the red brake warning lamp
(page 334) illuminates and/or warn-
ing messages appear in the multifunc-
tion display (
page 361), the brake
system is malfunctioning. Follow the in-
structions of the warning message(s)
and have the brake system checked
immediately.
Warning!
G
Have brake pad replacement and other work
on the electro-hydraulic brake system car-
ried out by qualified technicians only. Con-
tact an authorized Mercedes-Benz Center
for further information. The electro-hydrau-
lic brake system must be deactivated prior
to working on the system. High pressure is
intermittently built up in the system as part
of its automatic self-test. In addition, the
system is automatically activated when the
vehicle is unlocked by remote control, when
the driver or passenger door is opened,
when the SmartKey in the starter switch is
turned to position1 or the KEYLESS-GO*
start/stop button is pressed once, when the
brake pedal is depressed or when the park-
ing brake is released. Failure to deactivate
the system prior to maintenance will cause
brake pistons to extend and brake fluid to
leak, which may result in injuries (contu-
sions and acid burns). Extended brake pis-
tons may also cause injury.
96 Controls in detailIn the “Controls in detail” section you will
find detailed information on how to oper-
ate the equipment installed on your vehi-
cle. If you are already familiar with the
basic functions of your vehicle, this section
will be of particular interest to you.
To quickly familiarize yourself with the ba-
sic functions of the vehicle, refer to the
“Getting started” section of this manual.
The corresponding page numbers are giv-
en at the beginning of each segment.
For more information on locking and un-
locking, see the “Getting started” section
(page 34).
Locking and unlocking
SmartKey
Your vehicle comes supplied with two
SmartKeys, each with remote control and
a removable mechanical key.
The locking tabs for the mechanical key
portion of the two SmartKeys are a differ-
ent color to help distinguish each
SmartKey unit.
The SmartKey provides an extended oper-
ating range. To prevent theft, however, it is
advisable to only unlock the vehicle when
you are in close proximity to it.
The SmartKey centrally locks and unlocks:
the doors
the trunk lid
the glove box
the storage compartment under the
armrest
the storage compartment in the rear
the fuel filler flap

Step 5:
After the indicator lamp1 changes
from a slow to a rapidly flashing light,
release the hand-held remote control
button and the signal transmitter but-
ton.
Step 6:
Press and hold the just-trained signal
transmitter button (2, 3 or4) and
observe the indicator lamp1.If the indicator lamp1 stays on
constantly, programming is complete
and your device should activate when
the respective signal transmitter
button (2, 3 or4) is pressed and re-
leased.
Step 7:
To program the remaining two signal
transmitter buttons, repeat the steps
above starting with step 3.Rolling code programming
To train a garage door opener (or other
rolling code devices) with the rolling code
feature, follow these instructions after
completing the “Programming” portion
(steps 1 through 6) of this text. (A second
person may make the following training
procedures quicker and easier.)
Step 8:
Locate “training” button on the garage
door opener motor head unit.
Exact location and color of the button
may vary by garage door opener brand.
Depending on manufacturer, the
“training” button may also be referred
to as “learn” or “smart” button. If there
is difficulty locating the transmitting
button, refer to the garage door opener
operator’s manual.
iThe indicator lamp1 flashes immedi-
ately the first time the signal transmit-
ter button is programmed. If this button
has already been programmed, the in-
dicator lamp will only start flashing af-
ter 20 seconds.
iIf the indicator lamp1 flashes rapidly
for about 2 seconds and then turns to a
constant light, continue with
programming steps 8 through 12 as
your garage door opener may be
equipped with the “rolling code”
feature.
251 Controls in detail
Useful features
While still holding down the signal
transmitter button (2, 3 or4),
“cycle” your hand-held remote control
button6 as follows: Press and hold
button6 for 2 seconds, then release
it for 2 seconds, and again press and
hold it for 2 seconds. Repeat this se-
quence on the hand-held remote con-
trol until the frequency signal has been
learned. Upon successful training, the
indicator lamp1 will flash slowly and
then rapidly after several seconds.
Proceed with programming step 5 and
step 6 to complete.Reprogramming a single signal trans-
mitter button
To program a device using a signal trans-
mitter button previously trained, follow
these steps:
Switch on the ignition (
page 36).
Press and hold the desired signal
transmitter button (2, 3 or4).
Do not release the button.
The indicator lamp1 will begin to
flash after 20 seconds. Without releas-
ing the signal transmitter button, pro-
ceed with programming starting with
step 3.
iUpon completion of programming the
integrated remote control, make sure
you retain the hand-held remote con-
trol that came with the garage door
opener, gate operator or other device.
You may need it for use in other vehi-
cles, for future programming of an
integrated remote control, or simply for
continued use as a hand-held remote
control to operate the respective
device in other situations.
