Anti-theft systems
Immobilizer
The immobilizer prevents unauthorized
persons from starting your vehicle.
Activating
With the SmartKey: Remove the
SmartKey from the starter switch.

With the KEYLESS-GO*: Turn off the
engine (
page 317) and open the driv-
er’s door.
Deactivating

Switch on the ignition (
page 315).
Anti-theft alarm system
Once the alarm system has been armed, a
visual and audible alarm is triggered when
someone opens:

a door


the trunk


the hood
The alarm will stay on even if the activating
element (a door, for example) is immedi-
ately closed.
The alarm system will also be triggered
when


the vehicle is raised


the vehicle is opened with the
mechanical key


a door is opened from the inside
To cancel the alarm after it has been trig-
gered, see “Canceling the alarm”
(
page 76).1Indicator lamp

Arming: Lock your vehicle with the
SmartKey or KEYLESS-GO*.
The turn signal lamps flash three times
to indicate that the alarm system is ac-
tivated. The indicator lamp1 flashes
to indicate that the alarm system is
armed.
i
Starting the engine will also deactivate the
immobilizer.
In case the engine cannot be started (yet the ve-
hicle’s battery is charged), the system is not op-
erational. Contact an authorized Mercedes-Benz
Center or call 1-800-FOR-MERCedes (in the
USA), or 1-800-387-0100 (in Canada).
i
If the alarm stays on for more than
30 seconds, a call to the Response Center is ini-
tiated automatically by the Tele Aid system
(
page 462) provided Tele Aid service was sub-
scribed to and properly activated, and that nec-
essary mobile phone, power supply and GPS
coverage are available.


141 Control systems
COMAND navigation (introduction)
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.

Your vehicle comes supplied with two
SmartKeys, each with remote control and
a removable mechanical key.
The locking tabs for the mechanical key
portion of the two SmartKeys are of differ-
ent color to help distinguish each
SmartKey unit.
The SmartKey provides an extended oper-
ating range. To prevent theft, however, it is
advisable to only unlock the vehicle when

and/or serious personal injury.Warning!
G
To prevent possible personal injury, always
keep hands and fingers away from the door
