Warning!
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 338) and
warning messages in the instrument cluster
( page 345) come on while driving. To
brake, the driver must then apply signifi-
cantly greater brake pedal pressure and
depress the pedal much further to obtain
the expected braking effect. If necessary,
apply full pressure to the brake pedal.
Brakes may only be applied to the front
wheels. Stopping distance is increased!
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.
G
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, refer to "Towing the vehicle"
( page 408).
The SBC brake system is automatically ac-
tivated when you
unlock the vehicle with the SmartKey
or the KEYLESS-GO*
open the driver's or passenger door
turn the SmartKey in the starter switch
to position 1
in vehicles with KEYLESS-GO*, press
the start/stop button on the gear
selector lever once
depress the brake pedal
release the parking brake

If 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
returns 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 338) illuminates and/or warn-
ing messages appear in the instrument
cluster ( page 345), the brake system
is malfunctioning. Follow the instruc-
tions of the warning message(s) and
have the brake system checked imme-
diately.
