Important safety notes G
WARNING
Operating the integrated information systems and communications equipment in the vehicle
while driving will distract you from traffic con-
ditions. You could then lose control of the
vehicle. There is arisk of an accident.
Only operate these devices if road traffic con-
ditions permit. If you are unsure about the surrounding conditions, pull over to
asafe
location and make entries only while the vehi- cle is stationary.
You must observe the legal requirements for the countryinw hich you are currently driving when
operating the navigation system.
General notes Correct functioning of the navigation system
depends, amongst other things, on GPS recep-
tion. In certain situations, GPS reception may be
impaired, there may be interference or there
may be no reception at all, e.g. in tunnels or
multi-storey car parks.

Importan tsafety notes G
WARNING
If antifreeze comes into contact with hot com- ponents in the engine compartment, it may
ignite. There is arisk of fire and injury.
Let the engine cool dow nbefore yo utop up
the antifreeze .Make sur ethat antifreeze is
not spilled next to the filler neck. Thoroughly clea
nthe antifreeze from components before
starting the engine.
! Only ad
dcoolant that has bee npremixed
with the desire dantifreeze protection. You
coul dotherwise damag ethe engine.
Furthe rinformatio noncoolants can be found
in the Mercedes-Benz Specifications for Ser-
vice Products, MB Specifications for Service
Products 310.1, e.g. on the Internet at
http://bevo.mercedes-benz.com .Orcontact
aq ualifie dspecialist workshop.
! Always use
asuitabl ecoolant mixture, even
in countries where hig htemperatures prevail.
Otherwise ,the engine cooling system is not
sufficiently protected from corrosion and
overheating.
i Have the coolant regularly replaced at a
qualified specialist workshop and the replace- ment confirmed in the Service Booklet.
Comply with the important safety precautions
for service products whe nhandling coolant
(Y page 371).
The coolant is amixture of water and anti-
freeze/corrosion inhibitor. It is responsible for
the following:
R anti-corrosion protection
R antifreeze protection
R raising the boiling point
If antifreeze/corrosion inhibito rispresent in the
correct concentration, the boiling point of the
coolant during operation will be approximately
130 †.
The antifreeze concentrate/corrosion inhibitor
concentration in the engine cooling system
should:
R be at least 50%. Thi swillp rotect the engine
cooling system against freezing dow nto
approximatel y-37 †.
R not excee d55% (antifreeze protection down
to -45 †). Hea twillo therwise not be dissipa-
ted as effectively.
Mercedes-Benz recommends an antifreeze/
corrosion inhibito rconcentrate in accordance
with MB Specifications for Service Products
310.1.
i Whe
nthe vehicle is first delivered, it is filled
with acoolant mixtur ethat ensures adequate
antifreeze and corrosion protection. 376
