305 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 vehi
cles 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 specifi
cation 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 recommen
dations for scheduled oil changes. Failure to
do so will result in engine or emission control
system damage not covered by the smart
Limited Warranty.
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 infor
mation.
Air conditioning refrigerantR134a (HFC) refrigerant and special PAG
lubricating oil are used in the air conditioning
system.!
Never use R12 (CFC) or mineralbased
lubricating oil. Otherwise damage to the sys
tem will occur.
Brake fluidOnly brake fluid approved by smart is recom
mended. Any authorized smart center will
provide you with additional information.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 condi
tions, 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 re
placed regularly. Refer to your vehicle’s
Maintenance Booklet for replacement
interval.

Premium unleaded gasoline
!
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:
• Have the fuel tank only partially filled with
unleaded regular gasoline and fill up with
premium unleaded gasoline as soon as
possible.
• Avoid full throttle driving and abrupt
acceleration.
• 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.
•Do not exceed
2/3 of maximum accelerator
pedal position if the vehicle is fully loaded
or operating in mountainous terrain.
Fuel requirementsOnly use premium unleaded fuel:
• The octane number (posted at the pump)
must be 91 min.
It is an average of both the R
esearch
O
ctane N
umber (RON) and the M
otor O
ctane
N
umber (MON): (RON+MON) /2. This is also
known as the ANTIKNOCK 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.
G
Warning!
Gasoline is highly flammable and poison
ous. 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.
