Checking the coolant level
XStop your vehicle as far away from traffic as
possible on level ground.
XSwitch off the engine.
XSecure the vehicle to prevent it from rolling
away.
XOpen the hood (Ypage 218).
XSlowly turn cap:half a turn counter-clock-
wise to allow excess pressure to escape.
XTurn cap :further and remove it.
XCheck the coolant level.
If the coolant reaches the maximum mark on
coolant expansion tank ;, there is enough
coolant in coolant expansion tank ;.
Adding coolant
XIf the coolant drops under the minimum mark
on coolant expansion tank ;, add coolant to
the maximum mark.
Observe the information on coolant mixture
ratio and water quality in the "Technical data"
section (

GWARNING
Service products may be poisonous and haz-
ardous to health. There is a risk of injury.
Comply with instructions on the use, storage
and disposal of service products on the labels
of the respective original containers. Always
store service products sealed in their original
containers. Always keep service products out
of the reach of children.
Brake fluid is hazardous to health. Also observe
the safety notes in the "Service products and
capacities" section (
Ypage 277).
GWARNING
The brake fluid constantly absorbs moisture
from the air. This lowers the boiling point of
the brake fluid. If the boiling point of the brake
fluid is too low, vapor pockets may form in the
brake system when the brakes are applied
hard. This would impair braking efficiency.
There is a risk of an accident.
You should have the brake fluid renewed at
the specified intervals.
!Brake fluid corrodes paint, plastic and rub-
ber. If paint, plastic or rubber has come into
contact with brake fluid, rinse with water
immediately.
Have the brake fluid renewed every 2 year sat a
qualified specialist workshop. Observe the infor- mation on brake fluid in the "Technical data"
section (
Ypage 283).
Check the brake fluid level regularly, e.g. weekly
or when refueling.

DEF consumption
DEF consumption depends on operational and
driving conditions and it is not necessary to wait
until the next scheduled service to replenish the
fluid. Fluid should be added regularly to the DEF supply reservoir during vehicle operation or, at
the latest, after receiving the first warning mes-
sage via the on-board computer.
Low ambient temperatures
DEF freezes at a temperature of approximately
12 ‡(Ò11 †). The vehicle is equipped with a DEF
preheating system at the factory. Winter oper-
ation is therefore also guaranteed at tempera-
tures under 12 ‡ (Ò11 †).
iIf you add DEF at temperatures below 12 ‡
(Ò11 †) it is possible that the level is not
shown correctly due to the frozen DEF.
Drive for at least 20 minutes (heating phase in
the tank activated) and then stop the vehicle
for at least 30 seconds. The level is then
shown correctly.
Additives
!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 addi-
tives or tap water will invalidate the New Vehi-
cle Limited Warranty.
Storage
!Containers made of aluminum, copper, cop-
per alloys as well as unalloyed or galvanized
steel are not suitable for storing DEF. If stored
in these types of containers, DEF could cause
constituents of these metals to dissolve and
cause irreparable damage to the exhaust gas
aftertreatment.
Damage caused by such impurities in the DEF
will invalidate the New Vehicle Limited War-
ranty.
Only store DEF in containers made of hi
gh-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 DEF (e.g. caused by other ser-
vice products, cleaning agents, dust, etc.)
result in increased emissions, malfunctions,
catalytic converter damage or engine dam-
age.
The purity of DEF is essential to prevent mal-
functions 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.
% Environmental note
Dispose of DEF in an environmentally responsi-
ble manner.

Multi-grade engine oils of the prescribed SAE
class (viscosity) may be used all year round, tak-
ing the outside temperatures into account.
Engine oil viscosity
!If the SAE viscosity class of the engine oil
used does not cover the outside temperature
range in which you are operating the vehicle,
it must be changed in good time, in particular
before the cold season commences. Using an
engine oil that does not have adequate tem-
perature characteristics can lead to engine
damage.
The temperature range information of the SAE
classification always refers to that of fresh oil.
The temperature characteristics of the engine
oil may deteriorate significantly due to aging
in use, especially at low outside tempera-
tures.
We recommend that you change the engine
oil before the cold season commences. Use
an approved engine oil of the specified SAE
class.
Engine oil SAE classification
Viscosity indicates the flow characteristics of a
fluid. If an engine oil has a high viscosity, this
means that it is thick; a low viscosity means that it is thin.
Depending on the respective outside tempera-
tures, select an engine oil according to SAE
classification (viscosity). The table displays the
SAE classification to be used. The low temper-
ature characteristics of engine oils can notice-
ably deteriorate during operation, e.g. from
aging, soot and fuel accretion. For this reason,
regular oil changes using an approved engine oil
from the suitable SAE classification are urgently
recommended.
Additives
!Do not use any additives in the engine oil.
This could damage the engine.
Miscibility of engine oils
!Mixing oils reduces the benefits of using
high grade engine oils.
We recommend that you only add engine oil of
the same quality grade and SAE class as used
when the engine oil was last changed.
If, in exceptional cases, oil of the type in the
engine is not available, top up using another
approved mineral or synthetic engine oil.
If the quality grade is not available for diesel
engines, you may also add engine oils meeting
the requirements in MB Sheet Number 228.5,
229.3 or 229.5. The quantity to be added is then
limited to a maximum of 1 qt (1 l).
12If the quality grade is not available for diesel engines, you may also add engine oils meeting the requirements
of MB Sheet No. 228.5, 229.3 or 229.5. The quantity to be added is then limited to a maximum of 1 qt (1 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 func-
tion 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 regenera-
tion of the diesel particle filter.
Depending on the driving style, the vehicle con-
sumes a maximum of 1.0 qt (1.0 l)of engine oil
over a distance of 620 miles (1000 km).
Oil consumption may be higher if:
Rthe vehicle is new.
Ryou mainly operate the vehicle under arduous
operating conditions.
Ryou frequently drive at high engine speeds.
Regular maintenance is one of the preconditions
for moderate rates of consumption.
You can only estimate the oil consumption after
you have driven a considerable distance.
Check the engine oil level on a regular basis, e.g.
weekly or each time you refuel (
Ypage 220).

Coolant is a mixture of water and antifreeze/
corrosion inhibitor. It performs the following
tasks:
Rcorrosion protection
Rantifreeze protection
Rraises the boiling point
When the vehicle is first delivered, it is filled with
a coolant mixture that ensures adequate anti-
freeze and corrosion protection. Coolant must
be used in the system all year round to ensure
anti-corrosion protection and a raised boiling
point – even in countries with high outside tem-
peratures.
To prevent damage to the engine cooling sys-
tem, use only approved corrosion inhibitor/anti-
freeze that comply with the Mercedes-Benz
Specifications for Service Products.
We recommend corrosion inhibitor/antifreeze
that meets the requirements in MB Specifica-
tions for Service Products Sheet Number 325.
Check the antifreeze/corrosion inhibitor con-
centration in the coolant every six months.
The percentage of corrosion inhibitor/anti-
freeze additive in the engine cooling system
should:
Rbe at least 50%. This way, the engine cooling
system is protected against freezing down to
approximately -35 ‡ (-37 †).
