Standing water
Do not drive through flooded areas or water
of unknown depth. Before driving through
water, determine its depth. Never acceler-
ate before driving into water.
If you must drive through standing water,
drive slowly to prevent water from entering

WARNING
Always fasten items being carried as
securely as possible.
In an accident, during hard braking or sud-
den maneuvers, loose items thrown around
inside the vehicle may injure vehicle
occupants.
The cargo compartment is the preferred
place to carry objects. Control and operation of radio trans-
mitters

WARNING
Please do not forget that your primary
responsibility is to drive the vehicle
safely. Only operate the radio or tele- phone

if road, weather and traffic condi-
tions permit.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approx-
imately 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 elec-
tronic 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 tem-
perature may rise.
! Excessive coolant temperature causes
the red coolant temperature warning
lamp 00AC in the instrument cluster to
come on.
The drive system should not be operated
with the red coolant temperature warn-
ing lamp 00ACilluminated. Doing so may
cause serious damage to the drive system
and the high-voltage battery, which is
not covered by the smart Limited War-
ranty.

Retrofitting electrical and electronic
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 trans-
mitters in the vehicle you must have such
retrofits approved. smart approves the
installation of telephones and radio devi-
ces 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 maxi-
mum values. Frequency range
(band) Maximum transmit-
ting power (Watts)
Short wave
(<50 MHz) 100
2 m wavelength 50
0.7 m wavelength 35
0.25 m wavelength 10

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-reflec-
tion
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 electro-
magnetic fields.
Because of this, have the external antenna
installed exclusively at a qualified spe-
cialist 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.
