Engine oils

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
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 by

the 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.

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

G

Warning!

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

G

Warning!

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 capacities

Z

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 Research Octane
Number (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,
smart recommends the use of additives
approved by us for use on smart vehicles.
Contact an authorized smart center for a
listing of approved product(s). Follow
directions on 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/rear window washer system

During all seasons:

X

Use a windshield washer concentrate
labeled for summer and water for
temperatures above freezing point.

X

Use a windshield washer concentrate
labeled for winter and water for
temperatures below freezing point.

Warning!

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.

>> Technical data.

Z

Anticorrosion/antifreeze

Your vehicle contains a number of
aluminum parts. The use of aluminum
components in motor vehicle engines
necessitates that anticorrosion/
antifreeze coolant used in such engines be
specifically formulated to protect the
aluminum parts.
Failure to use such anticorrosion/
antifreeze coolant will result in a
significantly shortened service life.

Therefore, the following product is
strongly recommended for use in your
vehicle: MB 325.0 Anticorrosion/
Antifreeze agent.
Before the start of the winter season (or
once a year in hot southern regions), you
should have the anticorrosion/antifreeze
concentration checked.
The coolant is also regularly checked each
time you bring your vehicle to an
authorized smart center for service.
