The TIN is a unique identifier which
facilitates efforts by tire manufactures 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” 0003, “Tire size”002B,
“Tire type code” 002A, and “Date of
manufacture” 0028.
i For illustration purposes only. Actual
data on tires are specific to each vehicle
and may vary from data shown in above
illustration.
DOT (Department of Transportation) Tire branding symbol
0002which denotes the
tire meets requirements of the U.S.
Department of Transportation.
Manufacturer’s identification mark Manufacturer’s identification mark
0003
denotes the tire manufacturer.
New tires have a mark with two symbols.
Retreaded tires have a mark with four
symbols. For more information on
retreaded tires (Y page 122).
Tire size Code
002Bindicates the tire size. Tire type code Tire type code
002Amay, at the option of the
manufacturer, be used as a descriptive
code for identifying significant
characteristics of the tire.
Date of manufacture Date of manufacture
0028identifies the week
and year of manufacture.
The first two figures identify the week,
starting with “01” to represent the first
full week of the calendar year. The second
two figures represent the year.
For example, “3202” represents the 32nd
week of 2002. Tire ply material

WARNING
Always fasten items being carried as
securely as possible.
In an accident, during hard braking or
sudden maneuvers, loose items thrown
around inside the vehicle may injure
vehicle occupants.

WARNING
Please do not forget that your primary
responsibility is to drive the vehicle
safely. Only operate the radio or
telephone 8
if road, weather and traffic
conditions permit.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering adistance of 44 feet
(approximately 14 m) every second.
Telephones and two-way radios G
WARNING
Never operate radio transmitters equipped
with a built-in or attached antenna (i.e.
without being connected to an external antenna) from inside the vehicle while the
drive system is switched on. Doing so could
lead to a malfunction of the vehicle’s
electronic system, possibly resulting in an
accident and/or serious personal injury.
Radio transmitters, such as a mobile phone
or a citizens band unit should only be used
inside the vehicle if they are connected to
an antenna that is installed on the outside
of the vehicle.
Refer to the radio transmitter operation
instructions regarding use of an external
antenna. Coolant temperature
During severe operating conditions and
stop-and-go city traffic, the coolant
temperature may rise.
! Excessive coolant temperature causes
the red coolant temperature warning
lamp 0005 in the instrument cluster to
come on.
The drive system should not be operated
with the red coolant temperature
warning lamp 0005illuminated. Doing
so may cause serious damage to the drive
system and the high-voltage battery,
which is not covered by the smart Limited
Warranty.

temperature warning lamp ( Ypage 165). Driving abroad
Abroad, there is an extensive smart service
network at your disposal. If you plan to
drive into areas which are not listed in the
index of your smart center directory, you
should request pertinent information from
an authorized electric drive smart center.

devices
Electrical and electronic devices can
endanger vehicle operating safety.
! Damage or consequential damage due to
retrofitting a device in the vehicle is
not covered by smart’s warranty.
If you install telephones or radio
transmitters in the vehicle you must have
such retrofits approved. smart approves
the installation of telephones and radio
devices if the work is done professionally
and the device is connected to a low-
reflection exterior antenna.
The transmitting power of the telephone or
radio must not exceed the following
maximum values. Frequency range

WARNING
Radio transmitters can interfere with the
vehicle’s electronic system, endanger the
operating safety of the vehicle and thus
your own safety, if
R there is no external antenna
R the external antenna is not low-
reflection
R the external antenna is incorrectly
installed
Excessive electromagnetic radiation can
damage your health and that of others.
Using an external antenna addresses and
considers the concerns currently being
discussed in scientific circles about the health hazards possibly posed by
electromagnetic fields.
Because of this, have the external antenna
installed exclusively at a qualified
specialist workshop which has the
necessary specialist knowledge and tools
to carry out the work required, e.g. at a
smart center. In particular, work relevant
to safety or on safety-related systems must
be carried out at a qualified specialist
workshop.
