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-
