cooling MERCEDES-BENZ C CLASS 2016 User Guide

i The current status of the cooling function is
displayed in the climate control bar: A/C ON
– activated, A/C OFF – deactivated.
i Deactivating the cooling with air dehumidi-
fication function reduces fuel consumption.
Synchronizing the climate control set-
tings Use s Sync (synchronization) to select the cli-
mate control setting for all zones together s or
separately S .X
Call up the climate control menu
( Y
page 302).X
Slide 6 the controller repeatedly until the
bottom bar is activated. X
To select s Sync : turn and press the con-
troller. X
Switch the synchronization function on s or
off S .

Navigation mode
Important safety notes
G WARNING
If you operate information systems and com-
munication equipment integrated in the vehi-
cle while driving, you will be distracted from
traffic conditions. You could also lose control
of the vehicle. There is a risk of an accident.
Only operate the equipment when the traffic
situation permits. If you are not sure that this
is possible, park the vehicle paying attention
to traffic conditions and operate the equip-
ment when the vehicle is stationary.
You must observe the legal requirements for the
country in which you are currently driving when
operating the navigation system.
General notes
Among other things, correct functioning of the
navigation system depends on GPS reception. 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
parking garages. Audio 20 is equipped with MARGIN ®
MAP PILOT
(see the manufacturer's operating instructions).
The Garmin ®
MAP PILOT operating instructions
are stored on the SD memory card as a PDF file.
The SD card box contains a quick guide.
The following descriptions apply to navigation
with COMAND. Further information can be
found in the Digital Operator's Manual.

Notes for route types: R
Eco Route R
Dynamic Traffic Route
Traffic reports on the route for the route guid-
ance are taken into account. R
Calculate Alternative Routes
Different routes are being calculated. Instead
of Start select the Continue menu item.
Notes for route options: R
Use Toll Roads
The route calculation includes roads which
require you to pay a usage fee (toll). R
Use Vignette Roads (not available in all
countries)
The route calculation includes roads which
require you to pay a time-based fee (vignette).
A vignette allows temporary use of the route
network, e. g. 10 days or 1 year. R
Use Carpool Lanes (only available in the
USA)
Prerequisite: your vehicle meets the access
conditions for carpool lanes.
Carpool lanes will be included if the carpool
lanes option is activated.

Additives
! Do no t use any additive s in th e engin e oil.
This could damag e th e engine.
Brake fluid
G WARNIN G
The brak e fluid constantl y absorbs moisture
from th e air. This lower s th e boiling poin t of
th e brak e fluid . If th e boiling poin t of th e brak e
fluid is to o low, vapo r pockets may for m in th e
brak e system when th e brakes are applie d
hard. This would impair braking efficiency.
There is a ris k of an accident.
You should hav e th e brak e fluid renewed at
th e specifie d intervals.
When handlin g brak e fluid , observ e th e impor-
tan t safet y note s on servic e products
( Y
page 388).
The brak e fluid chang e intervals can be foun d in
th e Maintenance Booklet .
Only use brak e fluid approve d by Mercedes-
Benz in accordanc e wit h MB-Freigabe or MB -
Approval 331.0.
Information about approve d brak e fluid can be
obtained at any qualified specialis t workshop or
on th e Internet at
http://bevo.mercedes-benz.co m.
i Have the brake fluid regularly replaced at a
qualified specialist workshop in accordance
with the replacement intervals and the
replacement confirmed in the Maintenance
Booklet.
Coolant
Important safety notes
G WARNING
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 Ser-
vice Products, MB BeVo 310.1, e.g. on the
Internet at http://bevo.mercedes-benz.com.
Or contact 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.
i Have the coolant regularly replaced at a
qualified specialist workshop and the replace-
ment confirmed in the Maintenance Booklet.
Comply with the important safety precautions
for service products when handling coolant
( Y
page 388).
The coolant is a mixture of water and anti-
freeze/corrosion inhibitor. It performs the fol-
lowing tasks: R
corrosion protection R
antifreeze protection R
raising the boiling point
If the coolant has antifreeze protection down to
-35 ‡ (-37 †), the boiling point of the coolant
during operation is approximately 266 ‡
(130 †).
The antifreeze/corrosion inhibitor concentra-
tion in the engine cooling system should: R
be at least 50%. This will protect the engine
cooling system against freezing down to
approximately -35 ‡ (-37 †). R
not exceed 55% (antifreeze protection down
to -49 ‡ [-45 †]). Otherwise, heat will not be
dissipated as effectively.
Mercedes-Benz recommends an antifreeze/
corrosion inhibito r concentra te in accordance
w
ith MB Specifications for Service Products
310.1.
i When the vehicle is first delivered, it is filled
with a coolant mixture that ensures adequate
antifreeze and corrosion protection.392
