X
If necessary, take a break. X
Confirm the message by pressing the v
button on the steering wheel.
On long journeys, take regular breaks in good
time to allow yourself to rest properly. If you
do not take a break and ATTENTION ASSIST
still detects increasing lapses in concentra-
tion, you will be warned again after
15 minutes at the earliest. This will only hap-
pen if ATTENTION ASSIST still detects typical
indicators of fatigue or increasing lapses in
concentration.
If a warning is output in the multifunction dis-
play, a service station search is performed in
COMAND. You can select a service station
and navigation to this service station will then
begin. This function can be activated and
deactivated in COMAND.
Lane Tracking package
General notes
The Lane Tracking package consists of Blind
Spot Assist ( Y
page 205) and Lane Keeping
Assist ( Y
page 207).
Blind Spot Assist
General notes
Blind Spot Assist monitors the areas on either
side of the vehicle that are not visible to the
driver with two lateral, rear-facing radar sen-
sors. A warning display in the exterior mirrors
draws your attention to vehicles detected in
the monitored area. If you then switch on the
corresponding turn signal to change lane, you
will also receive an optical and audible warn-
ing.
Blind Spot Assist supports you from a speed
of approximately 20 mph (30 km/h). Important safety notes
G WARNING
Blind Spot Assist does not react to: R
vehicles overtaken too closely on the side,
placing them in the blind spot area R
vehicles which approach with a large speed
differential and overtake your vehicle
As a result, Blind Spot Assist may not give
warnings in such situations. There is a risk of
an accident.
Always observe the traffic conditions care-
fully, and maintain a safe lateral distance.
Blind Spot Assist is only an aid. It may fail to
detect some vehicles and is no substitute for
attentive driving. Always ensure that there is
sufficient distance to the side for other road
users and obstacles.
i USA only:
This device has been approved by the FCC
as a "Vehicular Radar System". The radar
sensor is intended for use in an automotive
radar system only. Removing, tampering
with, or altering the device will void any
warranties, and is not permitted by the
FCC. Do not tamper with, alter, or use in
any non-approved way.
Any unauthorized modification to this
device could void the user’s authority to
operate the equipment.
Radar sensors
The radar sensors for Blind Spot Assist are
integrated into the rear bumper. Make sure
that the bumpers are free from dirt, ice or
slush. The sensors must not be covered, for
example by cycle racks or overhanging loads.
Following a severe impact or in the event of
damage to the bumpers, have the function of
the radar sensors checked at a qualified spe-
cialist workshop. Blind Spot Assist may no
longer work properly. Driving systems 205

Emergency call Important safety notes
G WARNING
It can be dangerous to remain in the vehicle,
even if you have pressed the SOS button in an
emergency if: R
you see smoke inside or outside of the vehi-
cle, e.g. if there is a fire after an accident R
the vehicle is on a dangerous section of
road R
the vehicle is not visible or cannot easily be
seen by other road users, particularly when
dark or in poor visibility conditions
There is a risk of an accident and injury.
Leave the vehicle immediately in this or simi-
lar situations as soon as it is safe to do so.
Move to a safe location along with other vehi-
cle occupants. In such situations, secure the
vehicle in accordance with national regula-
tions, e. g. with a warning triangle.
General notes
Observe the notes on system activation
( Y
page 282).
An emergency call is dialed automatically if an
air bag or Emergency Tensioning Device is
triggered. You cannot end an automatically
triggered emergency call yourself.
An emergency call can also be initiated man-
ually.
As soon as the emergency call has been ini-
tiated, the indicator lamp in the SOS button
flashes. The Connecting Call
message
appears in the multifunction display.
The audio output is muted. Once the connection has been made, the
Call Connected
message appears in the
multifunction display.
All important information on the emergency is
transmitted, for example: R
current location of the vehicle (as deter-
mined by the GPS system) R
vehicle identification number R
information on the severity of the accident
Shortly after the emergency call has been ini-
tiated, a voice connection is automatically
established between the Customer Assis-
tance Center and the vehicle occupants. R
If the vehicle occupants respond, the
Mercedes-Benz Customer Assistance Cen-
ter attempts to get more information on the
emergency. R
If there is no response from the vehicle
occupants, an ambulance is immediately
sent to the vehicle.
If no voice connection can be established to
the Mercedes-Benz Customer Assistance
Center, the system has been unable to initiate
an emergency call.
This can occur, for example, if the relevant
mobile phone network is not available. The
indicator lamp in the SOS button flashes con-
tinuously.
The Call Failed message appears in the
multifunction display and must be confirmed.
In this case, summon assistance by other
means.

G WARNING
Electrostatic build-up can lead to the creation
of sparks, which could ignite the highly explo-
sive gases of a battery. There is a risk of an
explosion.
Before handling the battery, touch the vehicle
body to remove any existing electrostatic
build-up.
The highly flammable gas mixture forms when
charging the battery as well as when jump-
starting.
Always make sure that neither you nor the
battery is electrostatically charged. A build-
up of electrostatic charge can be caused, for
example: R
by wearing clothing made from synthetic
fibers R
due to friction between clothing and seats R
if you push or pull the battery across the
carpet or other synthetic materials R
if you wipe the battery with a cloth
G WARNING
During the charging process, a battery produ-
ces hydrogen gas. If a short circuit occurs or
sparks are created, the hydrogen gas can
ignite. There is a risk of an explosion. R
Make sure that the positive terminal of a
connected battery does not come into con-
tact with vehicle parts. R
Never place metal objects or tools on a bat-
tery. R
It is important that you observe the descri-
bed order of the battery terminals when
connecting and disconnecting a battery. R
When jump-starting, make sure that the
battery poles with identical polarity are
connected. R
It is particularly important to observe the
described order when connecting and dis-
connecting the jumper cables. R
Never connect or disconnect the battery
terminals while the engine is running.
G WARNING
Battery acid is caustic. There is a risk of injury.
Avoid contact with skin, eyes or clothing. Do
not inhale any battery gases. Do not lean over
the battery. Keep children away from batter-
ies. Wash away battery acid immediately with
plenty of clean water and seek medical atten-
tion.
H Environmental note
Batteries contain dangerous
substances. It is against the
law to dispose of them with
the household rubbish. They
must be collected separately
and recycled to protect the
environment.
Dispose of batteries in an
environmentally friendly
manner. Take discharged
batteries to a qualified spe-
cialist workshop or a special
collection point for used bat-
teries.
! Have the battery checked regularly at a
qualified specialist workshop.
Observe the service intervals in the Main-
tenance Booklet or contact a qualified spe-
cialist workshop for more information.
! You should have all work involving the
battery carried out at a qualified specialist
workshop. In the exceptional case that it is
necessary for you to disconnect the battery
yourself, make sure that: R
you switch off the engine and remove the
key. On vehicles with KEYLESS-GO,
ensure that the ignition is switched off.
Check that all the indicator lamps in the
instrument cluster are off. Otherwise,316
