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 mois-
ture 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 Mainte-
nance Booklet for replacement interval.
Only brake fluid approved by smart is rec-
ommended. Any authorized smart center
will provide you with additional informa-
tion.
Premium unleaded gasoline
G
WARNING
Gasoline is highly flammable and poison-
ous. It burns violently and can cause ser-
ious personal injury.
Never allow sparks, flame or smoking mate-
rials near gasoline!
Turn off the engine before refueling.
Whenever you are around gasoline, avoid
inhaling fumes and skin or clothing con-
tact. Extinguish all smoking materials.
Direct skin contact with fuels and the inha-
lation of fuel vapors are damaging to your
health.

and performance, premium unleaded gas-
oline must be used. If premium unleaded
gasoline is not available and low octane
