73 Safety and Security
Driving safety systems
The SBC brake system is automatically ac-
tivated when you:

unlock the vehicle with the key or the
KEYLESS-GO* card


open the driver’s or passenger door


turn the key in the starter switch to
position1


in vehicles with KEYLESS-GO*, press
start/stop button on selector lever
once


depress the brake pedal


release the parking brake
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 253) and
the warning messages (
page 265) light up
while driving. To brake, the driver must then
apply significantly greater brake pedal pres-
sure and depress the pedal much further to
obtain the expected braking effect. If neces-
sary, apply full pressure to the brake pedal.
Brakes are only 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.
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 in-
formation, refer to “Towing the vehicle”
(page 325).
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 pump. This is
normal and not an indication of a mal-
function. Pedal travel returns to normal
when you release the brake pedal and
the sound soon ceases.

Anti-theft systems
Tow-away alarm
Once the tow-away alarm is armed, a visual
and audible alarm will be triggered when
someone attempts to raise the vehicle.
Arming tow-away alarm
When you lock your vehicle, the tow-away
alarm is automatically armed after about
30 seconds.
When you unlock your vehicle, the
tow-away protection disarms automatical-
ly.Disarming tow-away alarm
To prevent triggering the tow-away alarm
feature, switch off the tow-away alarm be-
fore towing the vehicle, or when parking on
a surface subject to movement, such as a
ferry or auto train.
The switch is on the center console be-
tween the driver’s seat and the passenger
seat.
1Tow-away alarm off switch
2Indicator lamp

Turn off the ignition and remove the
key.

Press switch1.
The indicator lamp2 in the switch
lights up briefly.

Lock your vehicle with the key or (vehi-
cles with KEYLESS-GO*) the lock but-
ton at each door handle.
The tow-away alarm remains disarmed un-
til you lock your vehicle again.
iThe tow-away protection alarm is trig-
gered, for example, if the vehicle is lift-
ed on one side.
If the alarm stays on for more than
20 seconds, an emergency call is initi-
ated automatically by the Tele Aid sys-
tem (
page 202) provided Tele Aid
service was subscribed to and properly
activated.
iYou cannot disarm the tow-away alarm
if the ignition is turned on.

to prevent stored objects from being thrown
about and injuring vehicle occupants during
an accident.

will ap-
pear in the multifunction display.
When the connection is established, the
message

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

ual for more information.
Warning!
G
If you feel at any way in jeopardy when in the
vehicle (e.g. smoke or fire in the vehicle, ve-
hicle in a dangerous road location), please
do not wait for voice contact after you have
pressed the emergency button. Carefully
leave the vehicle and move to a safe loca-
tion. The Response Center will automatically
contact local emergency officials with the
vehicle’s approximate location if they re-
ceive an automatic SOS signal and cannot
make voice contact with the vehicle occu-
pants.

Brakes
Warning!
G
The brake system requires electrical energy
for operation.
A malfunction in the vehicle’s power supply
or electrical system In such a case, the red
brake warning lamp (
page 253) and warn-
ing messages (
page 265) in the instru-
ment cluster light up while driving. To brake,
the driver must then apply significantly
greater brake pedal pressure and depress
the pedal much further to obtain the expect-
ed braking effect. If necessary, apply full
pressure to the brake pedal. Brakes are only
applied to the front wheels. Stopping dis-
tance 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 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, refer to "Towing the vehicle"
(page 325).
With the engine not running, there is no
power assistance for the steering system. In
this case, it is important to keep in mind that
a considerably higher degree of effort is nec-
essary to steer the vehicle.
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.

ervoir can result in spilling brake fluid on hot
engine parts and the brake fluid catching
fire. You can be seriously burned.
