Engine oils are specifically tested for
their suitability in our engines and
durability for our service intervals.
Therefore, only use engine oils and oil
filters required for vehicles with the
Maintenance System. For a listing of
approved engine oils and oil filters
contact an authorized smart center.
! Using engine oils and oil filters of
specification other than those expressly
required for the Maintenance System, or

intervals longer than those called for bythe Maintenance System will result in
engine or emission control system
damage not covered by the smart Limited
Warranty.
Please follow Maintenance System
recommendations for scheduled oil
changes. Failure to do so will result in
engine or emission control system
damage not covered by the smart Limited
Warranty.25 Use a windshield washer concentrate labeled for summer and water for temperatures above freezing
point or a windshield washer concentrate labeled for winter and water for temperatures below freezing
point.206Service fluids and capacities>> Technical data.* optional451_AKB; 3; 22, en-USd2ureepe,Version: 2.11.8.12009-07-27T09:36:34+02:00 - Seite 206

Viscosity grades for engine oils
Using the chart below, select oil viscosity
according to the lowest air temperature
expected before the next oil change.
Engine oil additives
! Do not blend oil additives with engine
oil. They may damage the engine.
Damage or malfunctions resulting from
blending oil additives are not covered
by the smart Limited Warranty. Any
authorized smart center will provide you
with additional information.
Air conditioning refrigerant
R134a (HFC) refrigerant and special
PAG lubricating oil are used in the air
conditioning system.
! Never use R 12 (CFC) or mineral-based
lubricating oil. Otherwise damage to the
system will occur.
Brake fluid
GWarning!
During vehicle operation, the boiling
point of the brake fluid is continuously
reduced through the absorption of moisture
from the atmosphere. Under extremely
strenuous operating conditions, this
moisture content can lead to the formation
of bubbles in the system, thus reducing the
system’s efficiency.
Therefore, the brake fluid must be replaced
regularly. Refer to your vehicle’s
Maintenance Booklet for replacement
interval.
Only brake fluid approved by smart is
recommended. Any authorized smart center
will provide you with additional
information.
Premium unleaded gasoline
GWarning!
Gasoline is highly flammable and
poisonous. It burns violently and can cause
serious personal injury.
Never allow sparks, flame or smoking
materials near gasoline!
Turn off the engine before refueling.
Whenever you are around gasoline, avoid
inhaling fumes and skin or clothing
contact. Extinguish all smoking materials.
Direct skin contact with fuels and the
inhalation of fuel vapors are damaging to
your health.
! To maintain the engine’s durability
and performance, premium unleaded
gasoline must be used. If premium
unleaded gasoline is not available and
low octane fuel is used, follow these
precautions:
R Have the fuel tank only partially filled
with unleaded regular gasoline and
fill up with premium unleaded
gasoline as soon as possible.
R Avoid full throttle driving and abrupt
acceleration.
R Do not exceed an engine speed of
3 000 rpm if the vehicle is loaded with
Service fluids and capacities207>> Technical data.451_AKB; 3; 22, en-USd2ureepe,Version: 2.11.8.12009-07-27T09:36:34+02:00 - Seite 207Z

Windshield washer concentrate is highly
flammable. Fire, naked flames and smoking
are prohibited when windshield washer
concentrate is being handled.
Coolants
The engine coolant is a mixture of water
and anticorrosion/antifreeze, which
provides:
R Corrosion protection
R Freeze protection
R Boiling protection (by increasing the
boiling point)
The cooling system was filled at the factory
with a coolant providing freeze protection
to approximately -35 ¦ (-37 ¥) and
corrosion protection.
! Add premixed coolant solution only.
Adding water and MB 325.0
Anticorrosion/Antifreeze separately
from each other, could cause engine
damage not covered by the smart Limited
Warranty.
If the antifreeze mixture is effective to
-35 ¦ (-37 ¥), the boiling point of the
coolant in the pressurized cooling system
is reached at approximately 266¦ (130 ¥).
The coolant solution must be used year
round, even in countries which have high
temperatures to provide the necessary
corrosion protection and increase
boil‑over protection. Refer to
Maintenance/ Service Booklet for
replacement interval.
Coolant system design and coolant used
determine the replacement interval. The
replacement interval published in the
Maintenance booklet is only applicable if
MB 325.0 Anticorrosion/Antifreeze
solution or other smart approved products
of equal specification are used to renew
the coolant concentration or bring it back
up to the proper level.
For information on other smart approved
products of equal specification, contact an
authorized smart center.
To provide important corrosion
protection, the solution must be at least
50% anticorrosion/antifreeze (equivalent
to freeze protection to approximately
-35 ¦ [-37 ¥]).
If you use a solution that is more than 55%
anticorrosion/antifreeze (freeze
protection to approximately -49 ¦
[(-45 ¥]), the engine temperature will
increase due to the lower heat transfer
capability of the solution. Therefore, do
not use more than this amount of
anticorrosion/antifreeze.
If the coolant level is low, water and
MB 325.0 Anticorrosion/Antifreeze should
be used to bring it up to the proper level
(have cooling system checked for signs of
leakage). Please make sure the mixture is
in accordance with label instructions.
Always use anticorrosion/antifreeze that
have been approved by smart. For
information contact an authorized smart
center.
The water in the cooling system must meet
minimum requirements, which are usually
satisfied by normal drinking water.
If you are not sure about the water quality,
consult an authorized smart center.Service fluids and capacities209>> Technical data.451_AKB; 3; 22, en-USd2ureepe,Version: 2.11.8.12009-07-27T09:36:34+02:00 - Seite 209Z
