made the emergency call. In this situation,
seek additional assistance by other means.
Roadside Assistance button X
Press Roadside Assistance button 0002.
This initiates a call to the Mercedes-Benz
Customer Assistance Center. The indicator
lamp in Roadside Assistance button 0002
flashes while the call is active. The
Connecting Call message appears on
the multifunction display. The audio output
is muted.
If a connection can be made, the CallConnected message appears in the
multifunction display.
If a cellular phone network is available and
there is sufficien tGPS reception, the mbrace
system transmits data to the Mercedes-Benz
Customer Assistance Center, for example:
R Current location of the vehicle
R Vehicle identification number
i The display of the audio system or
COMAND shows that an mbrace call is
active. During the call, you can change to
the navigation menu by pressing the NAVI
button on COMAND, for example.
Voice output is not available.
Av oice connection is established between
the Mercedes-Benz Customer Assistance
Center and the vehicle occupants.
From the vehicle remote malfunction
diagnosis, the Mercedes-Benz Customer Assistance center can ascertain the nature of
the problem (Y
page 289).
The Mercedes-Benz Customer Assistance
Center either sends a qualified Mercedes-
Benz technician or arranges for your vehicle
to be transported to the nearest authorized
Mercedes-Benz Center. You may be charged
for services such as repair work and/or
towing. Further details are available in your
mbrace manual.
i The mbrace system failed to initiate a
Roadside Assistance call if:
R the indicator lamp for Roadside
Assistance call button 0002is flashing
continuously.
R no voice connection to the Mercedes-
Benz Customer Assistance Center was
established.
This may be because the corresponding
mobile phone network is not available.

and can be found on th
etire sidewall
(Y page 346). If the tire pressures have been set to the
lower values for lighter loads and/or lower
road speeds, the pressures should be reset
to the higher values:
R if you want to drive with an increased load
and/or
R if you want to drive at higher road speeds.
i The tire pressures for increased loads
and/or higher road speeds, shown in the
tire pressure table, may have a negative
effect on driving comfort.
i For vehicles towing a trailer, the full load
value on the tire pressure label located on
the inside of the fuel filler flap is valid for
the rear axle.
Option 3) The tire pressure for the
emergency/collapsible spare wheel
(depending on vehicle equipment) can be
found:
R printed in yellow on the rim of the
emergency/collapsible spare wheel
R in the "Wheel and tire combinations"
section (Y page 357) in this Operator's
Manual
R on the Tire and Loading Information placard
on the B-pillar on the driver's side
If the tire pressure is not set correctly, this
can lead to an excessiv ebuild up of heat and
a sudde nloss of pressure.
For more information, contact a qualified
specialist workshop. Important notes on tire pressure
G
WARNING
If the tire pressure drops repeatedly, the
wheel, valve or tire may be damaged. Tire
pressure that is too low may result in a tire
blow-out. There is a risk of an accident.
R Check the tire for foreign objects.
R Check whether the wheel is losing air or the
valve is leaking.
If you are unable to rectify the damage,
contact a qualified specialist workshop. G
WARNING
If you fit unsuitable accessories onto tire
valves, the tire valves may be overloaded and
malfunction, which can cause tire pressure
loss. Due to their design, retrofitted tire
pressure monitors keep the tire valve open.
This can also result in tire pressure loss. There
is a risk of an accident.
Only screw the standard valve cap or other
valve caps approved by Mercedes-Benz for
your vehicle onto the tire valve.
To test tire pressure, use a suitable tire
pressure gauge. The outer appearance of a
tire does not permit any reliable conclusion
about the tire pressure. On vehicles equipped
with the electronic tire pressure monitoring
system, the tire pressure can be checked
using the on-board computer.
The tire temperature and pressure increase
when the vehicle is in motion .This is
dependent on the driving speed and the load.
Therefore, you should only correct tire
pressures when the tires are cold.
The tires are cold:
R if the vehicle has been parked without
direct sunlight on the tires for at least three
hours and
R if the vehicle has not been driven further
than 1 mile (1.6 km)
The tire temperature changes depending on
the outside temperature, the vehicle speed
and the tire load. If the tire temperature Tire pressure
