keyless MERCEDES-BENZ SL600 2005 R230 Owner's Guide

86 Safety and SecurityDriving safety systemsThe SBC brake system is automatically
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 SBC brake system is activated as
the brake pedal is first depressed, 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 SBC brake system
pump. This is normal and not an indica-
tion of a malfunction. Pedal travel re-
turns to normal when you release the
brake pedal and the sound soon ceas-
es.
If you experience the above while driv-
ing and the red brake warning lamp
(page 326) illuminates and/or warn-
ing messages appear in the multifunc-
tion display (
page 347), 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 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 re-
mote 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 parking brake is released. Failure
to deactivate the system prior to mainte-
nance will cause brake pistons to extend
and brake fluid to leak, which may result in
injuries (contusions and acid burns). Extend-
ed brake pistons may also cause injury.

87 Safety and Security
Driving safety systems
The SBC brake servo assistance switches
off automatically

approximately two minutes after you
turned the SmartKey in the starter
switch to position0 or removed the
SmartKey


approximately two minutes after you
pressed the KEYLESS-GO* start/stop
button to turn off the engine or power
supply and opened the driver’s door
(with driver’s door open, the starter
switch is set to position 0, same as
SmartKey removed from starter
switch)


approximately 20 seconds after you
locked the vehicle from outside Note on driving with the SBC brake
system


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
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 94).


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


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 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 37), 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
the SmartKey is then inserted in the
starter switch. The SmartKey will then
have priority over the KEYLESS-GO
function and the vehicle’s electrical
system will operate according to the
position of the SmartKey in the starter
switch, even stopping the engine.


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.
