The air conditioning improves the level of
comfort when driving at high outside
temperatures by cooling and dehumidifying
the air.Nearly all dust particles, pollutants, are
filtered out by an integrated particle filter
before outside air enters the passenger com

partment through the air distribution system.
It also operates when the air conditioning is
switched off and you have switched on the
blower.
The air conditioning only works when the
engine is running and the blower is switched
on. Maximum effectiveness is achieved if you
drive with the windows closed.
i
In warmer weather, ventilate the passen

ger compartment for a short period of time
before utilizing the air conditioning.

i
For illustration purposes only. Actual data
on tires are specific to each vehicle and may
vary from data shown in above illustration.
This marking tells you about the type of cord
and number of plies in the sidewall and under
the tread.
Tire and loading terminologyAccessory weight
The combined weight (in excess of those stan

dard items which may be replaced) of auto

matic transmission, power steering, power
brakes, power windows, power seats, radio,
and heater, to the extent that these items are
available as factory
installed equipment
(whether installed or not).
Air pressure
The amount of air inside the tire pressing
outward on each square inch of the tire.
Air pressure is expressed in pounds per
square inch (psi), or kilopascal (kPa) or bars.
Aspect ratio
Dimensional relationship between tire section
height and section width expressed in per

centage.Bar
Another metric unit for air pressure. There
are 14.5038 pounds per square inch (psi)
to 1 bar; there are 100 kilopascals (kPa)
to 1 bar.
Bead
The tire bead contains steel wires wrapped by
steel cords that hold the tire onto the rim.
Cold tire inflation pressure
Tire inflation pressure when your vehicle has
been sitting for at least 3 hours or driven no
more than 1 mile (1.6 km).
Curb weight

>> Operation PSI (Pounds per s
quare i
nch)
A standard unit of measure for air pressure

> bar, kilopascal (kPa).
Recommended tire inflation pressure
The recommended tire inflation pressure for
normal driving conditions is listed on the Tire
and Loading Information placard located on
driver’s door B
pillar and provides best
handling, tread life and riding comfort.
Rim
A metal support for a tire or a tire and tube
assembly upon which the tire beads are
seated.
Sidewall
The portion of a tire between the tread and
the bead.TIN (T
ire I
dentification N
umber)
Unique identifier which facilitates efforts by
tire manufacturers to notify purchasers in
recall situations or other safety matters
concerning tires and gives purchasers the
means to easily identify such tires. The TIN is
comprised of "Manufacturer’s identification
mark", "Tire size", "Tire type code" and "Date
of manufacture".
Tire load rating
Numerical code associated with the maximum
load a tire can support.
Tire ply composition and material used
This indicates the number of plies or the num

ber of layers of rubber
coated fabric in the
tire tread and sidewall. Tire manufacturers
also must indicate the ply materials in the tire
and sidewall, which include steel, nylon, poly

ester, and others.Tire speed rating
Part of tire designation; indicates the speed
range for which a tire is approved.
Total load limit
Rated cargo and luggage load plus
68 kilograms (150 lbs) times the vehicle’s
designated seating capacity.
Traction
Force exerted by the vehicle on the road via
the tires. The amount of grip provided.
Tread
The portion of a tire that comes into contact
with the road.
Treadwear indicators
Narrow bands, sometimes called "wear bars"
that show across the tread of a tire when only
1/16in (1.6 mm) of tread remains.

>> Operation
!
To prevent damage to the catalytic
converter, only use premium unleaded gaso

line in this vehicle.
Any noticeable irregularities in engine oper

ation should be repaired promptly. Otherwise,
excessive unburned fuel may reach the cata

lytic converter, causing it to overheat and
potentially start a fire.
It is essential to observe the following points,
as there is otherwise a danger of overheating
and the catalytic converter may be damaged.
• Fill up only with premium unleaded gasoline.
Even small quantities of leaded gasoline can
damage the catalytic converter.
• Make sure you adhere to the prescribed
service intervals.
• Never run the fuel tank empty.
• If the engine starts to misfire, bring the ve

hicle to an immediate standstill without en

dangering traffic.
• If the engine fails to start the first time, you
should not try to start it any more than
three times in succession.
• Do not try to start for more than four sec

onds at a time.
TiresTreadwear indicators (TWI) are required by
law. These indicators are located in six places
on the tread circumference and become visi

ble at a tread depth of approximately
1/16in
(1.6 mm), at which point the tire is considered
worn and should be replaced. The treadwear indicator appears as a solid
band across the tread.
Specified tire inflation pressures must be
maintained. This applies particularly if the
tires are subject to high loads (e.g. high
speeds, heavy loads, high ambient tempera

tures).
G
Warning!
If you feel a sudden significant vibration
or ride disturbance, or you suspect that
possible damage to your vehicle has
occurred, you should turn on the hazard
warning flashers, carefully slow down,
and drive with caution to an area which is
a safe distance from the road.
Inspect the tires and the vehicle under

body for possible damage. If the vehicle
or tires appear unsafe, have the vehicle
towed to the nearest smart center or tire
dealer for repairs.
G
Warning!
Although the applicable federal motor
vehicle safety laws consider a tire to be
worn when the treadwear indicators (TWI)
become visible at approximately
1/16in
(1.6 mm), we recommend that you do not
allow your tires to wear down to that
level. As tread depth approaches
1/8in
(3 mm), the adhesion properties on a wet
road are sharply reduced.
Depending upon the weather and/or road
surface (conditions), the tire traction
varies widely.

Vehicle care
224
>> Operation
Care tipsRegular and proper care will help to maintain
the value of your vehicle. The best way to pro

tect 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).
!
Follow the care tips. Wash your vehicle
preferably by hand.
While in operation, even while parked, your
vehicle is subjected to varying external influ

ences which, if gone unchecked, can attack
the paintwork as well as the vehicle underbody
and cause lasting damage.Such damage is caused not only by extreme
and varying climatic conditions, but also by:
•Air pollution
• Road salt
•Tar
• Gravel and stone chipping
To avoid paint damage, you should
immediately remove:
•Insects
• Bird droppings
• Tree sap, etc.
• Grease and oil
•Break fluid
•Coolant
•Fuel
•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.
G
Warning!
Many cleaning products can be hazard

ous. 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.
