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 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.
27 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. 220

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
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. Service fluids and capacities

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, 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/rear window washer system
During all seasons:
X Use a windshield washer concentrate
labeled for summer and water for
