more than two seconds.
A call to a Mercedes-Benz Roadside Assis-
tance Representative is initiated. Indicator
lamp ;in Roadside Assistance button :
flashes while the call is active. The
ConZ
necting Callmessage appears in the
multifunction display and COMAND is
muted.
If a connection can be made, the
Call ConZ
nectedmessage appears in the multifunction
display.
If a mobile phone network is available and
there is sufficient GPS reception, the mbrace
system transmits data to the Response Cen-
ter, for example:
R current location of the vehicle
R vehicle identification number
R vehicle model
R vehicle color
iThe COMAND display shows that an
mbrace call is active. You can change to the navigation menu by pressing the NAVI but-
ton on COMAND during the call. Voice out- put is not available.
A voice connection is established between
the Mercedes-Benz Roadside Assistance
Representative and the vehicle occupants. The Mercedes-Benz Roadside Assistance
Representative either sends a qualified
Mercedes-Benz technician or makes arrange-
ments for your vehicle to be transported to
the nearest authorized Mercedes-Benz Cen-
ter. You may be charged for services such as
repair work and/or towing. Further details
are available in your mbrace manual.
X Describe the type of assistance needed.
iIf the indicator lamp in Roadside Assis-
tance button :is flashing continuously
and no voice connection with the Response center has been established, then the
mbrace system has not been able to initiate
a Roadside Assistance call (e.g. the rele-
vant mobile phone network is not availa-
ble). The
CallFailedmessage appears in
the multifunction display.
X To end a call: press the~button on the
multifunction steering wheel.
or
X Press the corresponding COMAND button
to end a phone call.

: you are not
charged for services such as jump-starting,
providing a few gallons of fuel for a fuel tank that has been run dry or changing a faulty
tire with the vehicle's own spare wheel.

Regular checking of wheels and tires
GWARNING
Damaged tires can cause tire inflation pres-
sure loss. As a result, you could lose control ofyour vehicle. There is a risk of accident.
Check the tires regularly for signs of damage
and replace any damaged tires immediately.
R Regularly check the wheels and tires of
your vehicle for damage at least once a
month, as well as after driving off-road or
on rough roads. Damage includes bulges
and deformation on tires, cuts, punctures,
cracks or severe corrosion on wheels, for
example. Damaged wheels can cause a
loss of tire pressure.
R Regularly check the tire tread depth and
the condition of the tread across the whole
width of the tire ( Ypage 231). In order to
inspect the inner side of the tire surface,
turn the steering wheel to full lock.
R All wheels must have a valve cap to protect
the valve against dirt and moisture. Do notinstall anything onto the valve other than
the standard valve cap or a valve cap
approved by Mercedes-Benz for your vehi-
cle.
Do not install anything onto the valve, suchas tire pressure monitoring systems.
R You should regularly check the pressure of
all your tires including the spare wheel, par- ticularly prior to long trips. Adjust the tire
pressure as necessary ( Ypage 237).
The service life of tires depends, among other things, on the following factors:
R Driving style
R Tire pressure
R Distance covered
Tire tread
GWARNING
Insufficient tire tread will reduce tire traction.
The tire is no longer able to dissipate water.
This means that on wet road surfaces, the risk
of hydroplaning increases, in particular where
speed is not adapted to suit the driving con-
ditions. There is a risk of accident.
If the tire pressure is too high or too low, tires
may exhibit different levels of wear at differ-
ent locations on the tire tread. Thus, you
should regularly check the tread depth and
the condition of the tread across the entire
width of all tires.
Minimum tire tread depth for:
R Summer tires: âin (3 mm)
R M+S tires: ãin (4 mm)
For safety reasons, replace the tires before
the legally prescribed limit for the minimum
tire tread depth is reached.
Marking :shows the tread wear indicator
(TWI). The arrow indicates the placement of
the tire tread.
Do not drive with tires which have too little
tread depth. tire traction on wet road surfaces decreases significantly when the tread depth
is less than 1
/ 8 in (3 mm).
Treadwear indicators (TWI) are required by
law. Six indicators are positioned over the tire
tread. They are visible once the tread depth is
approximately 1
/ 16 in (1.6 mm). If this is the
case, the tire is so worn that it must be
replaced.
The recommended tread depth for summer
tires is at least 1
/ 8 in (3 mm). The recommen-
ded tread depth for winter tires is at least 1
/ 6
in (4 mm).

ured at a gas station with a pressure gauge.
The tire pressures shown by the on-board
computer refer to those measured at sea
level. At high altitudes, the tire pressure val-
ues indicated by a pressure gauge are higher
than those shown by the on-board computer. In this case, do not reduce the tire pressures.
The operation of the tire pressure monitor can
be affected by interference from radio trans-
mitting equipment (e.g. radio headphones,
two-way radios) that may be being operated
in or near the vehicle.

Checking the tire pressure electroni-cally
X Make sure that the SmartKey is in posi-
tion 2in the ignition lock ( Ypage 103).
X Press the =or; button on the steer-
ing wheel to select the
Serv.menu. X
Press the 9or: button to select
Tire Pressure.
X Press the abutton.
The current tire pressure of each tire is
shown in the multifunction display.
If the vehicle has been parked for over
20 minutes, the
Tire pressure will be
displayed after driving a few
minutesmessage appears.
After a teach-in process, the tire pressure
monitor automatically detects new wheels or
new sensors. As long as a clear allocation of
the tire pressure value to the individual
wheels is not possible, the
Tire Pressure
Monitor Activedisplay message is shown
instead of the tire pressure display. The tire
pressures are already being monitored.
iIf a spare wheel is mounted, the system
may continue to show the tire pressure of
the wheel that has been removed for a few minutes. Observe that the displayed value
is not the same as the current tire pressure
of the emergency spare wheel.
Tire pressure monitor warning mes-
sages
If the tire pressure monitor detects a signifi-
cant pressure loss on one or more tires, a
warning message is shown in the multifunc-
tion display. A warning tone also sounds and
the tire pressure warning lamp lights up in the
instrument cluster.
Each tire that is affected by a significant loss of pressure is highlighted in the pressure dis-
play.
X If the
Correct Tire Pressuremessage
appears in the multifunction display, check the tire pressure on all four wheels and cor-
rect it if necessary.
X If the
CheckTiresmessage appears in the
multifunction display, the tire pressure in
one or more tires has dropped significantly and the tires must be checked.
