the vehicle's high-voltage electrical system
checked by a qualified specialist workshop.
All of the vehicle's high-voltage electrical sys-
tem components are marked with yellow
warning stickers which warn you about high
voltages. The cables of the vehicle's high-
voltage electrical system are orange.
When towing a vehicle after an accident, be
sure to observe the following sections:
RTransporting the vehicle (Ypage 297)
RTowing the vehicle with the front axle raised
(
Ypage 297)
RTowing a vehicle with both axles on the
ground (
Ypage 296)
Read the important safety instructions on
towing away (
Ypage 294).
The ignition must be switched off when car-
rying out general tasks, such as changing
bulbs or checking the coolant level.
Automatic switching off of the vehicle's high-voltage electrical system
If the restraint systems are activated during
an accident, the vehicle's high-voltage elec-
trical system is automatically deactivated.
This is to ensure that you do not come into
contact with high voltage.
Automatic protection from switching
on of the vehicle's high-voltage electri-
cal system
The vehicle's high-voltage electrical system is
not activated when the vehicle is started if:
Ra serious electrical insulation malfunction
is detected in the vehicle's high-voltage
electrical system.
Ran electrical connection in the vehicle's
high-voltage electrical system is discon-
nected.
Automatic switching off of the charging
process
The charging process is deactivated automat-
ically if:
Rthe high-voltage battery is fully charged
The charging process is interrupted automat-
ically if:
Ra serious electrical insulation malfunction
is detected in the vehicle's high-voltage
electrical system.
Ran electrical connection in the vehicle's
high-voltage electrical system is discon-
nected.
High-voltage switch-off device
!The high-voltage system must only be
switched off at vehicle standstill by spe-
cially trained service engineers. Otherwise
the high-voltage system may be damaged.
Your vehicle is equipped with a high-voltage
switch-off device :which can be used to

XRaise the hood.
XPull support strut ?out of bracket A.
XLift up support strut ?and insert it into

Closing the hood
XRaise the hood slightly and, at the same
time, remove support strut ?from yellow
retaining clip =.
XSwing support strut ?down and press it
into bracket Auntil it engages.
XLower the hood and let it fall from a height
of approximately 8 in (20 cm).
XCheck that the hood has engaged properly.
If the hood can be raised slightly, it is not
properly engaged. Do not press the hood
closed. Open the hood again and close it
with a little more force.
Checking and adding other service
products
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.

XPark the vehicle on a level surface.
Only check the coolant level when the vehi-
cle is on a level surface and the drive sys-
tem has cooled down.
XTurn the SmartKey to position2in the igni-
tion lock (
Ypage 131).
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 131).
XSlowly turn cap :counter-clockwise 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
(
Ypage 336).
Windshield washer system
GWARNING
Certain components in the engine compart-
ment may be very hot, e.g. the drive system
and radiator. Working in the engine compart-
ment poses a risk of injury.
If possible, let the drive system cool down and only touch the components described in the
following.
GWARNING
Windshield washer concentrate is highly flam- mable. If it comes into contact with hot com-
ponents in the front compartment, it may
ignite. There is a risk of fire and injury.
Make sure that no windshield washer con-
centrate is spilled next to the filler neck.
XTo open: pull cap:upwards by the tab.
XAdd the premixed washer fluid.
XTo close: press cap :onto the filler neck
until it engages.
If the washer fluid level drops below the rec-
ommended minimum of 1 liter, a message
appears in the multifunction display prompt-
ing you to add washer fluid (
Ypage 227).
Further information on windshield washer
fluid/antifreeze (
Ypage 336).
ASSYST PLUS
Service message
The ASSYST PLUS service interval display
informs you of the next service due date.
You can find information on the type of ser-
vice and service intervals in the Maintenance
Booklet.
You can obtain further information from an
authorized Mercedes-Benz Center or at
http://www.mbusa.com (USA only).
The multifunction display shows a service
message for several seconds, e.g.:
RService A in .. Days
RService A Due
RService A Exceeded by .. Days
Depending on the operating conditions of the
vehicle, the remaining time or distance until
the next service due date is displayed.
The letter A
orB, possibly in connection with a
number or another letter, indicates the type

Coolant
Important safety notes
GWARNING
If antifreeze comes into contact with hot com- ponents in the engine compartment, it may
ignite. There is a risk of fire and injury.
Let the engine cool down before you add anti-
freeze. Make sure that antifreeze is not spilled
next to the filler neck. Thoroughly clean the
antifreeze from components before starting
the engine.
!Only add coolant that has been premixed
with the desired antifreeze protection. You
could otherwise damage the engine.
Further information on coolants can be
found in the Mercedes-Benz Specifications
for Service Products, MB BeVo 310.1, e.g.
on the Internet at
http://bevo.mercedes-benz.co m.Or con-
tact a qualified specialist workshop.
!Always use a suitable coolant mixture,
even in countries where high temperatures
prevail.
Otherwise, the engine cooling system is not
sufficiently protected from corrosion and
overheating.
iHave the coolant regularly replaced at a
qualified specialist workshop and the
replacement confirmed in the Maintenance
Booklet.
Comply with the important safety precautions
for service products when handling coolant
(
Ypage 335).
The coolant is a mixture of water and anti-
freeze/corrosion inhibitor. It performs the
following tasks:
Rcorrosion protection
Rantifreeze protection
Rraising the boiling point
If the coolant has antifreeze protection down
to -35 ‡(-37 †), the boiling point of the cool- ant during operation is approximately 266 ‡
(130 †).
The antifreeze/corrosion inhibitor concentra-
tion in the engine cooling syste
mshould:
Rbe at least 50%. This will protect the engine
cooling system against freezing down to
approximately -35‡(-37 †) .
Rnotexceed 55 %(antifreeze protection
do wn to -49 ‡ [-45 †]). Otherwise, heat
will not be dissipated as effectively.
Mercedes-Benz recommends coolant or anti-
freeze/corrosion inhibitor concentrate in
accordance with MB Specifications for Ser-
vice Products 310.1.
iWhen the vehicle is first delivered, it is fil-
led with a coolant mixture that ensures
adequate antifreeze and corrosion protec-
tion.
iThe coolant is checked with every main-
tenance interval at a qualified specialist
workshop.
