Emergency call
Important safety notes
GWARNING
It can be dangerous to remain in the vehicle,
even if you have pressed the SOS button in an emergency if:
Ryou see smoke inside or outside of the vehi-
cle, e.g. if there is a fire after an accident
Rthe vehicle is on a dangerous section of
road
Rthe vehicle is not visible or cannot easily beseen 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
(
Ypage 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

multifunction display.
All important information on the emergency is
transmitted, for example:
Rcurrent location of the vehicle (as deter-
mined by the GPS system)
Rvehicle identification number
Rinformation 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.
RIf the vehicle occupants respond, the
Mercedes-Benz Customer Assistance Cen-
ter attempts to get more information on the
emergency.
RIf 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

Checking coolant level
GWARNING
The cooling system is pressurized, particularly
when the motor is warm. If you open the cap,
you could be scalded if hot coolant sprays out.
There is a risk of injury.
Let the engine cool down before you open the
cap. Wear gloves and eye protection. Slowly
open the cap to relieve pressure.
!The coolant may only be checked and cor-
rected when the engine is cool (coolant
temperature below 104 ‡ (40 †). Check-
ing the coolant when the coolant tempera-
ture is above 104 ‡ (40 †) may result in
damage to the engine or to the engine cool-
ing system.
Example
XPark the vehicle on a level surface.
Only check the coolant level when the vehi-
cle is on a level surface and the engine has cooled down.
XTurn the SmartKey to position 2in the igni-
tion lock (
Ypage 147).
XCheck the coolant temperature display in
the instrument cluster.
The coolant temperature must be below
104 ‡ (40 †).
XTurn the SmartKey to position 0in the igni-
tion lock (
Ypage 147).
XSlowly turn cap :counter-clockwise and
to relieve excess pressure.
XTurn cap :further counter-clockwise and
remove it.
If the coolant is at the level of marker bar =
in the filler neck when cold, there is enough
coolant in coolant expansion tank ;.
XIf necessary, add coolant that has been tes-
ted and approved by Mercedes-Benz.
XReplace cap:and turn it clockwise as far
as it will go.
For further information on coolant, see
