ETS
The Electronic Traction System is a compo-
nent of ESP
®.
The Electronic Traction System (ETS) im-
proves the vehicle’s ability to utilize avail-
able traction, especially under slippery road conditions. The brakes are applied to
the spinning wheel and power is trans-
ferred to the wheel(s) with traction.
The ESP
® warning lampvin the instru-
ment cluster starts to flash at any vehicle
speed, as soon as a tire loses traction and
the wheel begins to spin.
When you switch off the ESP
®, the ETS is
still enabled.Switching off the ESP
®
To improve the vehicle’s traction, turn off
the ESP
® in driving situations where it
would be advantageous to have the drive
wheels spin and thus cut into surfaces for
better grip such as:
when driving with snow chains
in deep snow
in sand or gravel
i
The ESP
® will only function properly if you
use wheels of the recommended tire size
(
page 655).
!
Because of the ESP’s
® automatic operation,
the engine and ignition must be shut off
(SmartKey in starter switch position0 or1 or
KEYLESS-GO start/stop button* in position0
or1) when
the parking brake is being tested on a brake
test dynamometer
the vehicle is being towed with the
front/rear axle raised
Active braking action through the ESP
® may oth-
erwise seriously damage the brake system.
Warning!
G
If you are driving too fast, the Electronic
Traction System cannot reduce the risk of
an accident.
The ETS cannot prevent the natural laws of
physics from acting on the vehicle.i
If the yellow ESP
® warning lampv
comes on while driving, the ETS is being
switched off temporarily to prevent overheating
of the drive wheel brakes. In addition, the mes-
sage “ESP Currently unavailable See Oper. Man-
ual” appears in the multifunction display.
Warning!
G
The ESP
® should not be switched off during
normal driving other than in the circum-
stances described below. Disabling of the
system will reduce vehicle stability in stan-
dard driving maneuvers.
!
Turn the ESP
® on immediately if the afore-
mentioned circumstances do not apply anymore.
i
DISTRONIC Plus* cannot be activated when
the ESP
® has been switched off.

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.
76 Safety and SecurityAnti-theft systems
Disarming: Unlock your vehicle with
the SmartKey or KEYLESS-GO*.
The turn signal lamps flash once to in-
dicate that the alarm system is dis-
armed.
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.
To cancel the alarm after it has been trig-
gered, see “Canceling the alarm”
(page 76).
Arming: Lock your vehicle with the
SmartKey or KEYLESS-GO*.
The tow-away alarm is automatically
armed after about 30 seconds.
Disarming: Unlock your vehicle with
the SmartKey or KEYLESS-GO*.
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. To switch off the tow-away alarm, see
“Switching on/of the tow-away alarm”
(
page 228).
Canceling the alarm
To cancel the alarm, do one of the follow-
ing:
Insert the SmartKey in the starter
switch.
Press the Œ or ‹ button on the
SmartKey.
In vehicles with KEYLESS-GO*:
Grasp an outside door handle.
The SmartKey with KEYLESS-GO must
be within 3 ft. (1 m) of the vehicle.
Press the KEYLESS-GO start/stop but-
ton (
page 317).
The SmartKey with KEYLESS-GO must
be inside the vehicle.
i
If the turn signal lamps does not flash three
times one of the following elements may not be
properly closed:
a door
the trunk
Close the respective element and lock the vehi-
cle again.
i
The alarm system will rearm automatically
again after approximately 40 seconds if no door
was opened.
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 neces-
sary mobile phone, power supply and GPS
coverage are available.
i
When you unlock your vehicle, the tow-away
protection disarms automatically.
The tow-away alarm remains disarmed until you
lock your vehicle again.

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.

Warning!
G
Navigation announcements are intended to
direct you while driving without diverting
your attention from the road and driving.
Please always use this feature instead of
consulting the map display for directions.
Consulting the symbols or map display for
directions may cause you to divert your at-
tention from driving and increase your risk
of an accident.i
If Russian or Chinese is set as the system
language, the navigation announcements are in
English. You will find how to set the system lan-
guage on (
page 216).
Navigation announcements are muted during
telephone calls. You can, however, call up a cur-
rent announcement at any time. You can also
call up a current announcement at any time if
you have missed an announcement.
