! Damage or consequential damage due to
retrofitting a device in the vehicle is
not covered by smart’s warranty.
If you install telephones or radio
transmitters in the vehicle you must have
such retrofits approved. smart approves
the installation of telephones and radio
devices if the work is done professionally
and the device is connected to a low-
reflection exterior antenna.
The transmitting power of the telephone or
radio must not exceed the following
maximum values.Frequency range
(band)Maximum
transmitting
power (Watts)Short wave
(<50 MHz)1002 m wavelength500.7 m wavelength350.25 m wavelength10GWarning!
Radio transmitters can interfere with the
vehicle’s electronic system, endanger the
operating safety of the vehicle and thus
your own safety, if
R there is no external antenna
R the external antenna is not low-
reflection
R the external antenna is incorrectly
installed
Excessive electromagnetic radiation can
damage your health and that of others.
Using an external antenna addresses and
considers the concerns currently being
discussed in scientific circles about the
health hazards possibly posed by
electromagnetic fields.
Because of this, have the external antenna
installed exclusively at a qualified
specialist workshop which has the
necessary specialist knowledge and tools
to carry out the work required, e.g. at a
smart center. In particular, work relevant
to safety or on safety-related systems must
be carried out at a qualified specialist
workshop.

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
changing of oil and oil filter at change
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

a light load such as two persons and no
cargo.
R Do not exceed 2
/ 3 of maximum
accelerator pedal position if the
vehicle is fully loaded or operating in
mountainous terrain.
Fuel requirements
Only use premium unleaded fuel. The octane
number (posted at the pump) must be 91 min.
It is an average of both the
R esearch Octane
N umber (RON) and the Motor Octane Number
(MON): (RON+MON)/2. This is also known as
the ANTI‑KNOCK INDEX.
Unleaded gasoline containing oxygenates
such as ethanol, IPA, IBA and TBA can be
used provided the ratio of any one of these
oxygenates to gasoline does not exceed
10%; MTBE must not exceed 15%.
The ratio of methanol to gasoline must not
exceed 3% plus additional cosolvents.
Using mixtures of ethanol and methanol is
not allowed. Gasohol, which contains 10%
ethanol and 90% unleaded gasoline, can be
used.
These blends must also meet all other fuel
requirements, such as resistance to spark
knock, boiling range, vapor pressure, etc.
Gasoline additives
A major concern among engine
manufacturers is carbon build-up caused
by gasoline. smart recommends only the use
of quality gasoline containing additives
that prevent the build-up of carbon
deposits.
After an extended period of using fuels
without such additives carbon deposits can
build up, especially on the intake valves
and in the combustion area, leading to
engine performance problems such as:
R Warm-up hesitation
R Unstable idle
R Knocking/pinging
R Misfire
R Power loss
In areas where carbon deposits may be
encountered due to lack of availability of
gasolines which contain these additives,
the use of smart approved additives is
recommended. Contact an authorized smart
center for a listing of approved products.
Follow directions on the product label.
Do not blend other fuel additives with fuel.
This only results in unnecessary costs and
may be harmful to the engine operation.
! Damage or malfunction resulting from
poor fuel quality or from blending
additional fuel additives other than
those tested and approved by us for use
on smart vehicles are not covered by the
smart Limited Warranty.

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
