81 Safety and Security
Driving safety systems
SBC brake system
The SBC brake system combines a hydrau-
lic brake circuit with electronically con-
trolled brake servo assistance. You have
increased braking safety and improved
braking comfort.Warning!
G
Never ignore a brake malfunction indicated
in the speedometer display, for example by
the
;
(USA only) or
3
(Canada only)
indicator lamp. Refer to the “Practical hints”
section (
page 284). Also read and ob-
serve the messages in the instrument clus-
ter multifunction display (
page 299).
Warning!
G
The SBC brake system requires electrical
power to operate.
A malfunction in the vehicle’s power supply
or electrical system may impair brake sys-
tem operation and switch it into its emer-
gency operation mode. In such a case, the
red brake warning lamp (
page 284)
comes on and warning messages
(
page 299) appear in the multifunction
display while driving. To brake, the driver
must then apply significantly greater brake
pedal pressure and depress the pedal much
further to obtain the expected braking ef-
fect. If necessary, apply full pressure to the
brake pedal. Brakes are only applied to the
front wheels. Stopping distance is in-
creased!
If there is a malfunction in the SBC brake
system, we recommend that the vehicle be
transported with all wheels off the ground
using flatbed or appropriate wheel lift/dolly
equipment.
A tow bar must be used if circumstances do
not permit the use of the recommended
towing methods and the vehicle requires
towing with all four wheels on the ground.
Towing the vehicle with all four wheels on
the ground is only permissible for distances
up to 30 miles (50 km) and at a speed not to
exceed 30 mph (50 km/h). For more infor-
mation, see “Towing the vehicle”
(page 365).

between the driver’s seat and the passen-
ger seat.1Tow-away alarm off switch

Warning!
G
To help avoid personal injury during a colli-
sion or sudden maneuver, exercise care
when stowing objects in the vehicle. Put lug-
gage or cargo in the trunk if possible. Do not
pile luggage or cargo higher than the seat
backs. Do not place anything on shelf be-
hind roll bar.
Parcel nets cannot secure hard or heavy ob-
jects. Warning!
G
Keep compartment lids closed. This will help
to prevent stored objects from being thrown
about and injuring vehicle occupants during
an accident.

Roadside Assistance button •
The Roadside Assistance button• is
located below the center armrest cover.
Press and hold the button (for longer
than two seconds)
A call to a Mercedes-Benz Roadside
Assistance dispatcher will be initiated.
The button will flash while the call is in
progress. The message
Roadside as-
sistance – Connecting call
will ap-
pear in the multifunction display.
When the connection is established, the
message
Roadside assistance –
Call connected
appears in the multifunc-
tion display. The Tele Aid system will trans-
mit data generating the vehicle
identification number, model, color and lo-
cation (subject to availability of cellular
and GPS signals).A voice connection between the Roadside
Assistance dispatcher and the occupants
of the vehicle will be established. When a
voice connection is established the audio
system mutes and the message

ap-
pears in the multifunction display.

Describe the nature of the need for as-
sistance.
The Mercedes-Benz Roadside Assistance
dispatcher will either dispatch a qualified
Mercedes-Benz technician or arrange to
tow your vehicle to the nearest authorized
Mercedes-Benz Center. For services such
as labor and / or towing, charges may ap-
ply. Refer to the Roadside Assistance Man-
ual for more information.These programs are only available in the
USA:


Sign and Drive services: Services such
as jump start, a few gallons of fuel or
the replacement of a flat tire with the
vehicle spare tire are obtainable.


Remote Vehicle Diagnostics: This func-
tion permits the Mercedes-Benz
Roadside Assistance dispatcher to
download malfunction codes and actu-
al vehicle data.iThe indicator lamp in the Roadside
Assistance button• remains illumi-
nated in red for approximately ten sec-
onds during the system self-check after
switching on the ignition (together with
the SOS button and the Information
button¡).
See system self-check (
page 224) if
the indicator lamp does not come on in
red or stays on longer than approxi-
mately ten seconds.

240 OperationDriving instructionsPower assistance
Brakes
Warning!
G
The brake system requires electrical energy
for operation.
A malfunction in the vehicle’s power supply
or electrical system may impair brake sys-
tem operation and switch it into its emer-
gency operation mode. In such a case, the
red brake warning lamp (
page 284) and
warning messages (
page 291) in the in-
strument cluster come on while driving. To
brake, the driver must then apply signifi-
cantly greater brake pedal pressure and de-
press the pedal much further to obtain the
expected braking effect. If necessary, apply
full pressure to the brake pedal. Brakes are
only applied to the front wheels. Stopping
distance is increased! If there is a malfunc-
tion in the SBC brake system, we recom-
mend that the vehicle be transported with
all wheels off the ground using flatbed or ap-
propriate wheel lift/dolly equipment.
A tow bar must be used if circumstances do
not permit the use of the recommended
towing methods and the vehicle requires
towing with all four wheels on the ground.
Towing the vehicle with all four wheels on
the ground is only permissible for distances
up to 30 miles (50 km) and at a speed not to
exceed 30 mph (50 km/h). For more infor-
mation, see “Towing the vehicle”
(page 365).
With the engine not running, there is no
power assistance for the brake and steering
systems. In this case, it is important to keep
in mind that a considerably higher degree of
effort is necessary to brake and steer the ve-
hicle.
Warning!
G
After driving in heavy rain for some time
without applying the brakes or through wa-
ter deep enough to wet brake components,
the first braking action may be somewhat
reduced and increased pedal pressure may
be necessary to obtain expected braking ef-
fect. Maintain a safe distance from vehicles
in front.
Resting your foot on the brake pedal will
cause excessive and premature wear of the
brake pads.
It can also result in the brakes overheating
thereby significantly reducing their effec-
tiveness. It may not be possible to stop the
vehicle in sufficient time to avoid an acci-
dent.
