2016 MERCEDES-BENZ S CLASS engine coolant

Outside temperature display You should pay special attention to road condi-
tions when temperatures are around freezing
point.
Bear in mind that the outside temperature dis-
play indicates the temperature measured and
does not record the road temperature.
The outside temperature display is in the multi-
function display ( Y
page 258).
There is a short delay before a change in outside
temperature is shown in the multifunction dis-
play.
Coolant temperature display
G WARNING
Opening the hood when the engine is over-
heated or when there is a fire in the engine
compartment could expose you to hot gases
or other service products. There is a risk of
injury.
Let an overheated engine cool down before
opening the hood. If there is a fire in the
engine compartment, keep the hood closed
and contact the fire department.
! A display message is shown if the coolant
temperature is too high.
If the coolant temperature is above 257 ‡
(125 †) do not drive any further. The engine
will otherwise be damaged.
All vehicles except PLUG ‑ IN HYBRID vehicles:
the coolant temperature gauge is in the lower
area of the tachometer ( Y
page 33).
PLUG-IN HYBRID vehicles: the multifunction dis-
play shows the coolant temperature in the
Coolant submenu ( Y
page 269).
Under normal operating conditions and with the
specified coolant level, the coolant temperature
may rise to 255 ‡ (124 †). Operating the on-board computer

G WARNING
If engine oil comes into contact with hot com-
ponents in the engine compartment, it may
ignite. There is a risk of fire and injury.
Make sure that engine oil is not spilled next to
the filler neck. Let the engine cool down and
thoroughly clean the engine oil off the com-
ponents before starting the engine.
H Environmental note
When adding oil, take care not to spill any. If
oil enters the soil or waterways, it is harmful to
the environment.
! Only use engine oils and oil filters that have
been approved for vehicles with a service sys-
tem. You can obtain a list of the engine oils
and oil filters tested and approved in accord-
ance with the Mercedes-Benz Specifications
for Service Products at any Mercedes-Benz
Service center.
Damage to the engine or exhaust system is
caused by the following: R
using engine oils and oil filters that have not
been specifically approved for the service
system R
replacing engine oil and oil filters after the
interval for replacement specified by the
service system has been exceeded R
using engine oil additives.
! Do not add too much oil. adding too much
engine oil can result in damage to the engine
or to the catalytic converter. Have excess
engine oil siphoned off. Example X
Turn cap C counter-clockwise and remove it. X
Add engine oil.
If the oil level is at or below the MIN mark on
the oil dipstick, add 1.1 US qt (1.0 liter) of
engine oil. X
Replace cap C on the filler neck and tighten
clockwise.
Ensure that the cap locks into place securely. X
Check the oil level again with the oil dipstick
( Y
page 353).

Checking coolant level
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
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.356

Maintenance and care

X
Park the vehicle on a level surface.
Only check the coolant level when the vehicle
is on a level surface and the engine has cooled
down. X
Turn the SmartKey to position 2 in the ignition
lock ( Y
page 162).
or X
Press Start/Stop button twice ( Y
page 162).X
Check the coolant temperature display in the
instrument cluster.
The coolant temperature must be below
158 ‡ (70 †). X
Turn the SmartKey to position 0 ( Y
page 162)
in the ignition lock.
or X
Remove Start/Stop button from ignition lock
( Y
page 162). X
Slowly turn cap C counter-clockwise and to
relieve excess pressure. X
Turn cap C further counter-clockwise and
remove it.

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.
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 c oolant has antifreeze protection down to
- 35 ‡ (-37 †), the boiling point of the coolant
during operation is approximately 266 ‡
(130 †).
The antifreeze concentrate/corrosion inhibitor
concentration 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 inhibitor concentrate in accordance
with
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.
i The coolant is checked with every mainte-
nance interval at a qualified specialist work-
shop.
