Windshield washer system
G
WARNING
Certain components in the engine compart-
ment, such as the engine, radiator and parts
of the exhaust system, can become very hot.
Working in the engine compartment poses a
risk of injury.
Where possible, let the engine cool down and touch only the components described in the
following. G
WARNING
Windshield washer concentrate could ignite if it comes into contact with hot engine compo-
nents or the exhaust system. There is a risk of
fire and injury.
Make sure that no windshield washer con-
centrate is spilled next to the filler neck. Example
X To open: pull cap0043upwards by the tab.
X Add the premixed washer fluid.
X To close: press cap 0043onto 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 (Y page 251).
Further information on windshield washer
fluid/antifreeze (Y page 366). Maintenance
ASSYST PLUS
Service messages The ASSYST PLUS service interval display
informs you of the next service due date.
Information on the type of service and service
intervals (see the separate Maintenance
Booklet).
You can obtain further information from an
authorized Mercedes-Benz Center or at
http://www.mbusa.com (USA only).
i The ASSYST PLUS service interval display
does not show any information on the
engine oil level. Observe the notes on the
engine oil level (Y page 293).
The multifunction display shows a service
message for several seconds, e.g.: R Service A in .. Days Service A in .. Days
R Service A Due
Service A Due
R Service A Exceeded by .. Days
Service 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 Aor B
B, possibly in connection with a
number or another letter, shows the type of
service. A Astands for a minor service and B
B for
a major service.
You can obtain further information from an
authorized Mercedes-Benz Center.
The ASSYST PLUS service interval display
does not take into account any periods of
time during which the battery is disconnec-
ted.
Maintaining the time-dependent service
schedule:
X Note down the service due date displayed
in the multifunction display before discon-
necting the battery.
or X After reconnecting the battery, subtract
the battery disconnection periods from the
service date shown on the display. 296
MaintenanceMaintenance and care
If you or others come into contact with fuel,
observe the following:
R Wash away fuel from skin immediately
using soap and water.
R If fuel comes into contact with your eyes,
immediately rinse them thoroughly with
clean water. Seek medical assistance with- out delay.
R If fuel is swallowed, seek medical assis-
tance without delay. Do not induce vomit-
ing.
R Immediately change out of clothing which
has come into contact with fuel.
Flexible Fuel vehicles can be refueled with the
following fuel types:
R premium-grade unleaded gasoline
R E85 fuel
R a mixture of E85 fuel and premium-grade
unleaded gasoline
i Flexible Fuel vehicles can be recognized
by the Ethanol up to E85 sticker on the
inside of the fuel filler flap.
Fuel consumption
The energy content of E85 fuel is less than
that of the same amount of premium-grade
gasoline. The amount of fuel consumed when operating the vehicle with E85 fuel is there-
fore higher than with premium-grade gaso-
line.
Maintenance
Inform your authorized Mercedes-Benz Cen-
ter that you are operating or have operated
the vehicle with E85 fuel.
Low outside temperatures
If the outside temperature is below 32 ‡
(0 †), the starting procedure can take notice-
ably longer when operating with E85 fuel.
E85 fuel is not suitable for use at outside
temperatures under -4 ‡ (-20 †). Engine oil
General notes !
Never use engine oil or an oil filter of a
specification other than is necessary to ful- fill the prescribed service intervals. Do not
change the engine oil or oil filter in order to
achieve longer replacement intervals than
those prescribed. You could otherwise
cause engine damage or damage to the
exhaust gas aftertreatment.
Follow the instructions in the service inter-
val display regarding the oil change. Other-
wise, you may damage the engine and the
exhaust gas aftertreatment.
When handling engine oil, observe the impor- tant safety notes on service products
(Y page 361).
The engine oils are matched to the perform-
ance of Mercedes-Benz engines and service
intervals. You should therefore only use
engine oils and oil filters that are approved for vehicles with maintenance systems.
For a list of approved engine oils and oil filters, consult an authorized Mercedes-Benz Cen-
ter. Or visit the website
http://bevo.mercedes-benz.com.
The table shows which engine oils have been
approved for your vehicle.

Important safety notes The climate control system of your vehicle is
filled with refrigerant R
‑134a.
The instruction label regarding the refrigerant
type used can be found on the left, on the
underside of the hood.
! Only the refrigerant R‑
134a and the PAG
oil approved by Mercedes-Benz may be
used. The approved PAG oil may not be
mixed with any other PAG oil that is not
approved for R-134a refrigerant. Other-
wise, the climate control system may be
damaged.
Service work, such as topping up refrigerant
or replacing components, may only be carried
out by a qualified specialist workshop. All
applicable regulations must be adhered to,
SAE standard J639 included. Always have work on the climate control sys-
tem carried out at a qualified specialist work-
shop.
