Updating the map software
You can update the map software yourself
using a DVD.
Notes about handling DVDs
Only hold discs by the edge.
Handle discs carefully to prevent read
problems.
Avoid getting scratches, fingerprints
and dust on discs.
Use a commercially-available cleaning
cloth to clean discs. Do not wipe them
with a circular motion, but only in
straight lines from the center out-
wards.
Place discs back in their boxes after
use.
Protect discs from heat and direct sun-
light.
Updating process
The updating process has the following
phases:
Loading a DVD into the DVD changer
(page 142)
Updating process (
page 142)
i
The updating process can take between 10
and 60 minutes, depending on the size of the
map software. If the radio was switched on be-
fore you started the updating process, you can
still adjust the volume. You can also use
COMAND to operate the automatic air condition-
ing and to cancel the process. Other functions
are not operational.
If possible, carry out the update when the vehicle
is stationary.
i
If you carry out the update with the engine
switched off and the vehicle battery has insuffi-
cient power, COMAND may automatically switch
off during the process in order to protect the bat-
tery. If this occurs, restart the update with the
engine running period. Similarly, if the SmartKey
position is unintentionally switched to 0, restart
the update.Warning!
G
Never leave the engine running in an en-
closed space. The exhaust gases contain
carbon monoxide. Inhaling exhaust gases
constitutes a health hazard and could lead
to loss of consciousness or even death.
530 OperationWinter drivingBefore the onset of winter, have your
vehicle winterized at an authorized
Mercedes-Benz Center. This service
includes:
Check of anticorrosion and antifreeze
concentration.
Addition of cleaning concentrate to the
water of the windshield and headlamp
cleaning system. Add MB Concentrate
“S” to a premixed windshield washer
solvent/antifreeze which is formulated
for below freezing temperatures
(page 666).
Battery test. Battery capacity drops
with decreasing ambient temperature.
A well charged battery helps to make
sure that the engine can be started,
even at low ambient temperatures.
Tire change.
Winter tires
Always use winter tires at temperatures
below 45°F (7°C) and whenever wintry
road conditions prevail. Not all M+S rated tires provide special winter performance.
Make sure the tires you use show the
mountain/snowflake.marking on the
tire sidewall. These tires meet specific
snow traction performance requirements
of the Rubber Manufacturers Association
(RMA) and the Rubber Association of Can-
ada (RAC) and have been designed specif-
ically for use in snow conditions. Use of
winter tires is the only way to achieve the
maximum effectiveness of the ABS, EBP
and ESP
® in winter operation.
For safe handling, make sure that all
mounted winter tires are of the same make
and have the same tread design.Always observe the speed rating of the
winter tires installed on your vehicle. If the
maximum speed for which your tires are
rated is below the speed rating of your
vehicle, you must place a notice to this
effect where it will be seen by the driver.
Such notices are available from your tire
dealer or from any authorized
Mercedes-Benz Center.
Warning!
G
Winter tires with a tread depth under
1/6in
(4 mm) must be replaced. They are no
longer suitable for winter operation.
Warning!
G
If you use your spare tire when winter tires
are fitted on the other wheels, be aware that
the difference in tire characteristics may
very well impair turning stability and that
overall driving stability may be reduced.
Adapt your driving style accordingly.
Have the spare tire replaced with a winter
tire at the nearest authorized
Mercedes-Benz Center.
677 Technical terms
Restraint systems
Seat belts, belt tensioners, air bags
and child restraint systems. As inde-
pendent systems, their protective func-
tions complement one another.
Rim

Root directory
The uppermost directory on a storage
medium.
Run Flat Indicator
The Run Flat Indicator monitors the set
tire inflation pressures by evaluating
each wheel’s rotational speed. If a
wheel’s rotational speed changes due
to falling tire inflation pressure, a corre-
sponding warning message appears in
the ->Instrument cluster control sys-
tem.RON
(R
esearch O
ctane N
umber)
The Research Octane Number for gaso-
line as determined by a standardized
method. It is an indication of a gaso-
line’s ability to resist undesired detona-
tion (knocking). The average of both
the ->MON (Motor Octane Number)
and RON (Research Octane Number) is
posted at the pump, also known as AN-
TI-KNOCK INDEX.

The Tele Aid system consists of three
types of response: automatic and man-
ual emergency, Roadside Assistance
and information. Tele Aid is initially ac-
tivated by completing a subscriber
agreement and placing an acquain-
tance call. The Tele Aid system is oper-
ational provided that the vehicle’s
battery is charged, properly connected,
not damaged and mobile phone and
->GPS coverage is available.
Telematics
A combination of the terms “telecom-
munications” and “informatics.”
