>> Technical data.
!
Only use tires which have been tested and
approved by smart. Tires approved by smart
are developed to provide best possible
performance in conjunction with the driving
safety systems on your vehicle such as ABS
or ESP
®.
Using tires other than those approved by
smart may result in damage that is not
covered by the smart Limited Warranty.
!
Using tires other than those approved by
smart can have detrimental effects, such as
• poor handling characteristics
• increased noise
• increased fuel consumption
Moreover, tires and rims not approved by
smart may, under load, exhibit dimensional
variations and different tire deformation
characteristics that could cause them to come
into contact with the vehicle body or axle
parts. Damage to the tires or the vehicle may
be the result.
i
Further information on tires and rims is
available at any authorized smart center.
A placard with the recommended tire inflation
pressure is located on the driver’s door
Bpillar (
page 185).
The tire inflation pressure should be checked
regularly and should only be adjusted on cold
tires. Follow tire manufacturer’s maintenance
recommendation included with vehicle.

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.
