Adding engine oil G
WARNING
If engine oil comes into contact with hot
components 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
components before starting the engine.
! The alternator is located below the engine
oil filler neck.Ife ngine oil spills onto the
alternator, there is a dange rofalternator
damage. Be very careful when adding
engine oil. 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.
! 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.
! Do not use any additives in the engine oil.
This could damage the engine.

WARNING
The engine cooling system is pressurized,
particularly when the engine is warm. When
opening the cap, you could be scalded by hot
coolant spraying out. There is a risk of injury.
Let the engine cool down before opening the
cap. Wear eye and hand protection when
opening the cap. Open the cap slowly half a
turn to allow pressure to escape.
Only check the coolant level and/or fill the
coolant if the vehicle is on a level surface and
the engine has cooled down. The coolant
temperature must be below 122 ‡ (50 †).
! Check the engine cooling and heating
system regularly for leaks.
If a large quantity of coolant is lost, have
the cause traced and rectified at a qualified
specialist workshop. 244

d(DEF)
General notes !
Only use DEF in accordance with
ISO 22241. The exhaus tgas aftertreatment
system may otherwise be damaged.
Observe the MB Specifications for Service
Products, Sheet No. 352.0.
Damage caused by the use of other
reducing agents will invalidat ethe New
Vehicle Limited Warranty.
! If DEF comes into contact with a painted
or aluminum surface, wash the surface off
immediately with plenty of water.
High ambient temperatures When opening the DEF tank filler cap at high
outside temperatures, ammonia vapors may
escape. Ammonia vapors have a pungent
odor and are particularly irritating for your
skin, respiratory organs and eyes. This may
result in burning eyes, nose and throat, as
well as coughing and watering eyes. Do not
inhale ammonia vapors.
If DEF in the DEF reservoir heats up to
temperatures above 122 ‡
(50†) foralong
period of time (e.g. due to direct sunlight),
ammonia vapors form.
Low ambient temperatures DEF freezes at a temperature of
approximately 12
‡(002711 †). The vehicle is
equipped with a DEF preheating system at the
factory .This ensures that the vehicle can be
operated in winter, even at temperatures
below 12 ‡(002711 †).
Additives and tap water !
Do not mix DEF with any additives and do
not dilute DEF with tap water. Otherwise,
the exhaust gas aftertreatment may be
damaged.
Observe the MB Specifications for Service
Products, Sheet No. 352.0. Damage that arises through the use of
additives or tap water will invalidate the
New Vehicle Limited Warranty.
Storage !
Containers made of aluminum, copper,
coppe ralloys as well as unalloyed or
galvanized steel are not suitable for storing
DEF. If stored in these types of containers,
DE Fc ould cause constituents of these
metals to dissolve and cause irreparable
damage to the exhaust gas aftertreatment.
Damage caused by such impurities in the
DEFw ill invalidate the New Vehicle Limited
Warranty.
Only store DEF in containers made of high-
alloy Cr-Ni steel or Mo-Cr-Ni steel in
accordance with DIN EN 10 088-1/2/3 or
plastic containers made of polypropylene or
polyethylene.
Purity !
Impurities in DE F(e.g. caused by other
service products, cleaning agents, dust,
etc.) result in increased emissions,
malfunctions, catalytic converter damage
or engine damage.
The purity of DEFi s essential to prevent
malfunctions in the exhaust gas
aftertreatment.
If DEF is pumped out of the DEF tank, e.g.
during repair work, the same liquid must not
be used to refill the tank. Its purity is no longer
guaranteed.
Disposal Observe country-specific laws and
regulations when disposing of DEF.
0017Environmental note
Dispose of DEF in an environmentally
responsible manner.320

13.21 US qt. (12.5 l) Information about oil consumption
!
If the vehicle is predominantly used for
short-distance driving, this could lead to a
malfunction in the automatic cleaning
function for the diesel particle filter. As a
result, fuel may accumulate in the engine
oil and cause engine failure.
Therefore, if you mainly drive short
distances, you should drive on a highway or
on rural roads for 20 minutes every
310 miles (500 km). This ensures sufficient
regeneration of the diesel particle filter.
Depending on the driving style, the vehicle
consumes a maximum of 1.0 US qt (1.0 l)of
engine oil over a distance of 620 miles
(1000 km).
Oil consumption may be higher if:
R the vehicle is new.
R you mainly operate the vehicle under
arduous operating conditions.
R you frequently drive at high engine speeds.
Regula rmaintenance is one of the
preconditions for moderate rates of
consumption.
You can only estimate th eoil consumption
after you have drive naconsiderable distance.
Check the engine oil level on a regular basis,
e.g. weekly or each time you refuel
