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
