2017 MERCEDES-BENZ METRIS coolant

GVW (Gross Vehicle Weight)
The gross vehicle weight includes the weight of
the vehicle including fuel, tools, spare wheel,
accessories installed, occupants, luggage and
the drawbar noseweight if applicable. The gross
vehicle weight must never exceed the permissi-
ble gross weight (GVWR) specified on the
B-pillar on the driver's side (
Ypage 303).
GVWR (Gross Vehicle Weight Rating)
The GVWR is the maximum permitted gross
weight of the fully laden vehicle (weight of the
vehicle including all accessories, occupants,
fuel, luggage and the drawbar noseweight if
applicable). The permissible gross weight is
specified on the vehicle identification plate on
the B-pillar on the driver's side (
Ypage 303).
Maximum weight of the laden vehicle
The maximum weight is the sum of:
Rthe curb weight of the vehicle
Rthe weight of the accessories
Rthe load limit
Rthe weight of the factory installed optional
equipment
Kilopascal (kPa)
Metric unit for tire pressure. 6.9 kPa are the
equivalent of 1 psi. Another tire pressure unit is
bar. 100 kilopascals (kPa) are the equivalent of
1 bar.
Load index
In addition to the load bearing index, a load
index can be stamped onto the sidewall of the
tire. It specifies the load-bearing capacity of the
tire more precisely.
Curb weight
The weight of a vehicle with standard equipment
including the maximum filling capacity of fuel,
oil, and coolant. It also includes the air-condi-
tioning system and optional equipment if these
are installed on the vehicle, but does not include
passengers or luggage.
Maximum tire load
The maximum tire load in kilograms or pounds is
the maximum weight for which a tire is
approved.
Maximum permissible tire pressure
Maximum permissible tire pressure for one tire.
Maximum load on one tire
Maximum load on one tire. This is calculated by
dividing the maximum axle load of one axle by
two.
PSI (Pounds per square inch)
Standard unit of measurement for tire pressure.
Aspect ratio
Relationship between tire height and width in
percent.
Tire pressure
Pressure inside the tire applying an outward
force to every square inch of the tire's surface.
Tire pressure is specified in pounds per square
inch (psi), in kilopascal (kPa) or in bar. Tire pres-
sure should only be corrected when the tires are
cold.
Cold tire pressure
The tires are cold:
Rif the vehicle has been parked for at least
three hours without direct sunlight on the
tires, and
Rif the vehicle has not been driven further than
1 mile (1.6 km)
Tire tread
The part of the tire that comes into contact with
the road.
Tire bead
The tire bead ensures that the tire sits securely
on the wheel. There are several steel wires in the bead to prevent the tire from coming loose from
the wheel rim.
Sidewall
The part of the tire between the tread and the
tire bead.
Weight of optional extras
The combined weight of those optional extras
that weigh more than the replaced standard
parts and more than 2.3 kg (5 lbs). These
optional extras, such as high-performance
brakes, a roof rack or a high-performance bat-
tery, are not included in the curb weight and theweight of the accessories.

Important safety notes
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.
HEnvironmental note
Dispose of service products in an environ-
mentally responsible manner.
When handling, storing and disposing of any
service products, please observe the relevant
regulations.
Service products include the following:
RFuels, e.g. gasoline
RLubricants, e.g. engine oil, transmission oil
RCoolant
RBrake fluid
RWasher fluid
RClimate control system refrigerants
Approved service products comply with the
highest quality standards and are listed in the
Mercedes-Benz Specifications for Service Prod-
ucts. Only use service products approved for the
vehicle. This is an important condition for the
Limited Warranty.

Brake fluid
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.
When handling, storing and disposing of brake
fluid, please observe the relevant regulations
and the important safety notes for service prod-
ucts (
Ypage 304).
Over a period of time, the brake fluid absorbs
moisture from the air. This reduces its boiling
point.
Have the brake fluid replaced at specified inter-
vals by a qualified specialist workshop.
iThere is usually a notice in the engine com-
partment to remind you when the next brake
fluid change is due.
Use only approved brake fluids that comply with the Mercedes-Benz Specifications for Service
Products. Always check for the identification
DOT 4 plus. Information about approved brake fluids can be
obtained:

Coolant
Important safety notes
GWARNING
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.
!Take care not to spill any coolant on painted
surfaces. You could otherwise damage the
paintwork.
When handling, storing and disposing of coolant
and antifreeze, please observe the relevant reg-
ulations and the important safety notes for oper-
ating fluids (
Ypage 304).
Coolant additive with corrosion and
antifreeze protection
!Use only approved antifreeze/corrosion
inhibitor that complies with MB Specification for Service Products, Sheet Number 325.
Using other, non-approved antifreeze/corro-
sion inhibitors may cause damage to the cool-
ant system and reduce the engine's service
life.
The coolant is a mixture of water and antifreeze
and corrosion inhibitor. It performs the following
tasks:
RAnti-corrosion 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/corrosion protection. Coolant must
remain in the engine cooling system all year
round to ensure anti-corrosion protection and a
higher boiling point, even in countries with high
outside temperatures.

Check the antifreeze/corrosion inhibitor con-
centration inthe coolant every six months.
The percentage of corrosion inh ibitor/ant i-
freeze additiveinthe engine co oling system
should:
Rbe at least 50 %.This way, the engine co oling
system isprotected against freezing downto
approximate ly-35 ‡ (-37 †).
Rnot exceed 55% (antifreeze protection down
to -49 ‡ [-45 †]). Other wise, heat will not be
dissipated as effectively.
Mercedes-Benz recommends an antifreeze and
corrosion inhibitor that meets the requirements
in the Mercedes-Benz Specifications for Service
Products Sheet Number 325.

fied specialist workshop.

Climate control system refrigerants
Important safety notes
The climate control system of your vehicle is fil-
led with the refrigerant R‑ 134a.
The warning label for the refrigerant being used
can be found on the radiator cross member.
!Only the refrigerant R ‑134a and the PAG oil
approved by Mercedes-Benz may be used.
The approved PAG oil may not be mixed with
any other PAG oil that is not approved for
R-134a refrigerant. Otherwise, the climate
control system may be damaged. Maintenance work such as adding refrigerant or
replacing components may only be carried out
by a qualified specialist workshop. All applicable
regulations thereto and the SAE standard J639
must be adhered to.
All work on the climate control system should
always be carried out at qualified specialist
workshop.
