Cleaning the seat covers
General notes
!Do not use a microfiber cloth to clean
covers made out of real leather, artificial leather or DINAMICA. If used often, these
can damage the cover.
iNote that regular care is essential to
ensure that the appearance and comfort of
the covers is retained over time.
Genuine leather seat covers
Leather is a natural product.
It exhibits natural surface characteristics,
for example:
RDifferences in the texture
Rmarks caused by growth and injury
RSlight nuances of color
These are characteristics of leather and not
material defects.
!To retain the natural appearance of the
leather, observe the following cleaning
instructions:
RClean genuine leather covers carefully
with a damp cloth and then wipe the cov-
ers down with a dry cloth.
RMake sure that the leather does not
become soaked. It may otherwise become
rough and cracked.
ROnly use leather care agents that have
been recommended by smart. You can
obtain these from a qualified specialist
workshop.
Seat covers of other materials
!Observe the following when cleaning:
Rclean artificial leather covers with a
cloth moistened with a solution contain-
ing 1% detergent (e.g. dish washing liq-
uid).
Rclean cloth covers with a microfiber
cloth moistened with a solution contain-
ing 1% detergent (e.g. dish washing liq-
uid). Rub carefully and always wipe
entire seat sections to avoid leaving
visible lines. Leave the seat to dry
afterwards. Cleaning results depend on
the type of dirt and how long it has been
there.
Rclean DINAMICA covers with a damp cloth.
Make sure that you wipe entire seat sec-
tions to avoid leaving visible lines.
Cleaning the seat belts
GWARNING
Seat belts can become severely weakened if bleached or dyed. This could cause the seat
belts to tear or fail, for instance, in the
event of an accident. This poses an
increased risk of injury or fatal injury.
Never bleach or dye the seat belts.
!Do not clean the seat belts using chemical
cleaning agents. Do not dry the seat belts by
heating at temperatures above 176 ‡(80 †)
or in direct sunlight.
XUse clean, lukewarm water and soap solu-
tion.

Fuel consumption information
HEnvironmental note
CO
2(carbon dioxide) is the gas which sci-
entists believe to be principally respon-
sible for global warming (the greenhouse
effect). Your vehicle's CO
2emissions are
directly related to fuel consumption and
therefore depend on:
Refficient use of the fuel by the engine
Rdriving style
Rother non-technical factors, such as
environmental influences, road condi-
tions or traffic flow
You can minimize your vehicle's CO
2emis-
sions by driving carefully and having it
serviced regularly.
The vehicle will use more fuel than usual in
the following situations:
Rat very low outside temperatures
Rin city traffic
Ron short journeys
Rin mountainous terrain
Engine oil
General notes
!Never use engine oil or an oil filter of a
specification other than is necessary to
fulfill the prescribed service intervals.
Do not change the engine oil or oil filter in order to achieve longer replacement inter-
vals than those prescribed. You could oth-
erwise cause engine damage or damage to
the exhaust gas aftertreatment.
Follow the instructions in the service
interval display regarding the oil change.
Otherwise, you may damage the engine and
the exhaust gas aftertreatment.
When handling engine oil, observe the impor-
tant safety notes on service products
(
Ypage 207).
The engine oils are matched to the perform-
ance of smart engines and service intervals.
You should therefore only use engine oils and
oil filters that are approved for vehicles
with maintenance systems.
Consult a smart center to view a list of
approved engine oils and filters. Or visit the
website http://bevo.mercedes-benz.com.
The table shows which engine oils have been
approved for your vehicle.

Engine oil viscosity
Viscosity describes the flow characteristics
of a fluid. If an engine oil has a high viscos-
ity, this means that it is thick; a low viscos-
ity means that it is thin.
Select an engine oil with an SAE (viscosity)
classification suitable for the prevailing
outside temperatures. The table shows you
which SAE classifications are to be used. The
low-temperature properties of engine oils
can be significantly impaired during oper-
ation due to, for example, aging or soot and
fuel accretion. It is therefore strongly rec-
ommended that you carry out regular oil
changes using an approved engine oil with
the appropriate SAE classification.
Brake fluid
When handling brake fluid, observe the
important safety notes on service products
(
Ypage 207).
The brake fluid change intervals can be found
in the Maintenance Booklet.
Only use brake fluid approved by Mercedes-
Benz according to MB Approval 331.0.
Information about approved brake fluid can
be obtained at any qualified specialist work-
shop or on the Internet at
http://bevo.mercedes-benz.com.
iHave the brake fluid regularly replaced at
a qualified specialist workshop and the
replacement confirmed in the Maintenance
Booklet.
Coolant
General notes
!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 Service Products, MB BeVo 310.1, e.g. on
the Internet at
http://bevo.mercedes-benz.com. Or con-
tact 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.
iHave the coolant regularly replaced at a
qualified specialist workshop and the
replacement confirmed in the Maintenance
Booklet.
Comply with the important safety precautions
for service products when handling coolant
(
Ypage 207).
The coolant is a mixture of water and anti-
freeze/corrosion inhibitor. It performs the
following tasks:
Rcorrosion protection
Rantifreeze protection
Rraising the boiling point
If the coolant has antifreeze protection down
to -35 ‡(-37 †), the boiling point of the cool-
ant during operation is approximately 266 ‡
(130 †).
The antifreeze/corrosion inhibitor concen-
tration in the engine cooling system should:
Rbe at least 50 %. This will protect the
engine cooling system against freezing
down to around -13‡(-25 †).
Rnot exceed 50 % (antifreeze protection down
to-35 ‡[-37 †]). Otherwise, heat will not be
dissipated as effectively.
smart recommends an antifreeze/corrosion
inhibitor concentrate in accordance with MB
Specifications for Operating Fluids 310.1 or
325.6.
Antifreeze/corrosion inhibitor concentrate
in accordance with MB Specifications for
210Service products and filling capacities
>> Technical data.

Operating Fluids 310.1 and 325.6 can be mixed
together. An orange discoloration depending
on the mixing ratio does not affect the func-
tion.
iWhen the vehicle is first delivered, it is
filled with a coolant mixture that ensures
adequate antifreeze and corrosion protec-
tion.
iThe coolant is checked with every main-
tenance interval at a qualified specialist
workshop.
Windshield washer system
General notes
!Do not add distilled or de-ionized water
to the washer fluid container. Otherwise,
the level sensor may be damaged.
!Only MB SummerFit and MB WinterFit
washer fluid should be mixed together. The spray nozzles may otherwise become
blocked.
When handling washer fluid, observe the
important safety notes on service products
(
Ypage 207).
At temperatures above freezing:
XFill the washer fluid reservoir with a mix- ture of water and windshield washer fluid,
e.g. MB SummerFit.
Add 1 part MB SummerFit to 100 parts water.
At temperatures below freezing:
XFill the washer fluid reservoir with a mix-
ture of water and washer fluid, e.g. MB Win-
terFit.
The correct mixing ratio can be taken from
the information on the antifreeze protec-
tion container.
iAdd windshield washer fluid, e.g. MB
SummerFit or MB WinterFit, to the washer
fluid all year round.
Climate control system refrigerant
Important safety notes
The climate control system of your vehicle is
filled with refrigerant R‑134a.
The instruction label regarding the refrig-
erant type used can be found on the left, on the
underside of the hood.
!Only the refrigerant R‑134a and the PAG
oil approved by Mercedes-Benz may be
