Note on driving with the SBC


Following extended periods of only mi-
nor loads to your brake system, you
should occasionally apply the brakes
when traveling at high speeds. This im-
proves the grip of the brake pads.


After driving on wet or snow-covered
roads, you should apply your brakes
firmly before parking your vehicle. This
produces heat which serves to dry the
brake disks and help prevent corro-
sion.


On long and steep grades, shift to a
lower gear (gear range1, 2, or 3) to
prevent the brakes from overheating
and to reduce brake wear.


After hard braking, it is advisable to
drive on for some time so that the air
stream will cool down the brakes fast-
er.


Only Mercedes-Benz approved compo-
nents (e.g. brake pads) should be in-
stalled on your vehicle. Brake pads not
approved by Mercedes-Benz may im-
pair the safety of your vehicle.
Warning!
G
Have brake pad replacement and other work
on the SBC brake system carried out by
qualified technicians only. Contact an au-
thorized Mercedes-Benz Center for further
information. The SBC 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 acti-
vated when the vehicle is unlocked by
SmartKey, when the driver or passenger
door is opened, when the starter switch is
turned to position
1, when the brake pedal
is depressed or when the parking brake is
released. Failure to deactivate the system
prior to maintenance will cause brake pis-
tons to extend and brake fluid to leak, which
may result in injuries (contusions and acid
burns). Extended brake pistons may also
cause injury.
Warning!
G
Be very careful not to endanger other road
users when you apply the brakes.

Important notes on using KEYLESS-GO

You can also use the SmartKey with
KEYLESS-GO like a normal SmartKey
(page 98).


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


Always carry the SmartKey with
KEYLESS-GO with you.


Never store the SmartKey with
KEYLESS-GO together with:

electronic items such as a cellular
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.


In order to start the engine with the
SmartKey with KEYLESS-GO:

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


All the doors must be closed.


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


If you have started the engine with the
KEYLESS-GO start/stop button
(page 36), you can only turn it off
again with this button, even if you have
put the SmartKey in the starter switch
in the meantime.
This does not apply if, after starting, the
selector lever is still in positionP and
then the SmartKey is inserted in the
starter switch. The SmartKey will then
have priority over the KEYLESS-GO
iYou can also open and close the power
windows (
page 218) and tilt/sliding
sunroof* (page 223) or tilt/sliding
panel* (
page 229) using the Smart-
Key.
iWhen you unlock the vehicle, the SBC
brake system is activated (
page 90).
