Care tips
Regular and proper care will help to
maintain the value of your vehicle. The
best way to protect your vehicle from
harmful environmental influences is to
wash it and use protective treatments
regularly.
smart recommends that you care for the
paintwork

at least twice a year (e.g. in the
spring and autumn). G
WARNING
Many cleaning products can be hazardous.
Some are poisonous, others are flammable.
Always follow the instructions on the
particular container. Always open your
vehicle’s doors or windows when cleaning
the inside.
Never use fluids or solvents that are not
designed for cleaning your vehicle.
Always lock away cleaning products and
keep them out of reach of children.
! Follow

the care tips. Wash your vehicle
preferably by hand.
While in operation or even while parked,
your vehicle is subjected to varying
external influences, which left unchecked
can attack the paint as well as the vehicle
underbody and lead to permanent damage. 150
Vehicle care
>> Operation.

Such damage is caused not only by extreme
and varying climatic conditions, but also
by:
R
Air pollution
R Road salt
R Tar
R Gravel and stone chipping
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.
