Rims and tires
Notes
! 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 the ABS or the 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
R poor handling characteristics
R increased noise
R 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 B‑pillar.
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. Mobility
Your
vehicle is equipped with a tire repair
kit (Y page 186). In case of a flat tire, it
enables you to drive to the nearest
authorized smart center on the sealed tire. If the tire is damaged too severely for the
tire sealant to provide a reliable tire
repair:

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
