To avoid paint damage, you should
immediately remove:
R Insects
R Bird droppings
R Tree sap, etc.
R Grease and oil
R Brake fluid
R Coolant
R Fuel
R Tar spots
! Failure to remove such dirt
immediately can cause damage to the
paint or the soft top fabric*.
Environmental influences are not
covered by the smart Limited Warranty.
Frequent washing reduces and/or
eliminates the aggressiveness and potency
of the above adverse influences.
More frequent washings are necessary to
deal with unfavorable conditions:
R near the ocean
R in industrial areas (smoke, exhaust
emissions)
R during winter operation
You should check your vehicle from time to
time for stone chipping or other damage.
Any damage should be repaired as soon as
possible to prevent corrosion.
In doing so, do not neglect the underbody
of the vehicle. A prerequisite for a
thorough check is a washing of the
underbody followed by a thorough
inspection. Damaged areas need to be re-
undercoated.
Your vehicle has been treated at the factory
with a wax-base rustproofing in the body
cavities which will last for the lifetime of
the vehicle. Post-production treatment is
neither necessary nor recommended by
smart because of the possibility of
incompatibility between materials used in
the production process and others applied
later.We have selected vehicle-care products
and compiled recommendations which are
specially matched to our vehicles and
which always reflect the latest technology.
You can obtain smart approved vehicle-
care products at an authorized smart
center.
Scratches, corrosive deposits, corrosion
or damage due to negligent or incorrect
care cannot always be removed or repaired
with the vehicle-care products
recommended here. In such cases it is best
to seek aid at an authorized smart center.
The following topics deal with the cleaning
and care of your vehicle and give important
“how-to” information as well as references
to smart approved vehicle-care products.
Vehicle care
Contact an authorized smart center for
recommended and approved care products.
i Advice on caring for the soft top
system, see ( Y page 157).
GWarning!
After washing the vehicle, the brakes may
still be wet and thus their functionality
impaired. Therefore, when you start off,
brake lightly several times without
endangering traffic.

Replacing bulbs
About replacing bulbs
Safe vehicle operation depends on proper
exterior lighting and signaling. It is
therefore essential that all bulbs and lamp
assemblies are in good working order at all
times.
Correct headlamp adjustment is extremely
important. Have headlamps checked and
readjusted at regular intervals and when a
bulb has been replaced. Contact an
authorized smart center for headlamp
adjustment.
GWarning!
Bulbs and bulb sockets can be very hot.
Allow the lamp to cool down before changing
a bulb. Otherwise you could be burned if you
touch them.
Keep bulbs out of the reach of children.
Halogen lamps contain pressurized gas. A
bulb can explode if you:
R touch or move it when hot
R drop the bulb
R scratch the bulb
Wear eye and hand protection.
i If the headlamps or front fog lamps* are
fogged up on the inside as a result of
high humidity, driving the vehicle a
distance with the lights on should clear
up the fogging.
Notes on bulb replacement:
R Only use bulbs of the same type and with
the specified watt rating.
R Switch the lights off before replacing a
bulb to prevent short circuits.
R Always use a clean lint-free cloth when
handling bulbs.
R Your hands should be dry and free of oil
and grease.
R Avoid touching the glass of the bulb with
bare fingers.
R If the newly installed bulb does not come
on, contact an authorized smart center.
R Have the bulbs for the front fog lamps*
replaced at an authorized smart center.180Replacing bulbs>> Practical hints.* optionalBA 451 USA, CA Edition A 2011; 1; 4, en-UShereepeVersion: 3.0.3.62010-05-11T15:12:26+02:00 - Seite 180
to come off. This could cause an accident.
Be sure to use the correct wheel bolts.
GWarning!
Only use genuine smart wheel bolts. Other
wheel bolts may come loose.
Do not tighten the wheel bolts when the
vehicle is raised. Otherwise the vehicle
could fall off the jack.
XClean contact surfaces of wheel and wheel
hub.
! To avoid paint damage, place wheel flat
against hub and hold it there while
installing first wheel bolt.
XGuide the wheel onto the wheel hub and
push it on.
XInsert two wheel bolts and tighten them
slightly.
XVehicles with wheel trim cap on steel
rim: Attach the wheel trim cap so that it
is held by the two wheel bolts.
XInstall last wheel bolt and tighten it
slightly.
XLower the vehicle until the vehicle is
resting fully on its own weight.
XRemove the jack.XTighten the wheel bolts. Observe a
tightening torque of 80 lb-ft (110 Nm).
GWarning!
Have the tightening torque checked after
changing a wheel. The wheels could come
loose if they are not tightened to a torque
of 80 lb-ft (110 Nm).
Steel rim with wheel cover
XVehicles with wheel cover on steel rim:
Position wheel cover aperture \000F so
valve \000G fits through.
XPush the wheel cover evenly onto the
wheel rim with both hands.
XCheck that the wheel cover is fixed
securely to the wheel rim.
iThe Tire Pressure Monitoring System
(TPMS)* only functions on wheels that are
equipped with the proper electronic
sensors (Y page 129).
Battery
About the battery
Your vehicle’s battery is located in the
passenger footwell below the footrest
(Y page 197).
The battery should always be sufficiently
charged in order to achieve its rated
service life. Refer to Maintenance Booklet
for battery maintenance intervals.
If you use your vehicle mostly for short-
distance trips, you will need to have the
battery charge checked more frequently.
When replacing the battery, always use
batteries approved by smart.
Battery: 12 V and 42 Ah
If you do not intend to operate your vehicle
for an extended period of time, consult an

Notes
Vehicle components and their respective
lubricants must match. Therefore only use
products tested and approved by smart.

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
GWarning!
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
GWarning!
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.
