ECU SMART FORTWO COUPE 2012 Owner's Manual

B‑pillar (Y page 214). In addition, the
load must be distributed in such a way so
that the weight on each axle never exceeds
the
Gross Axle Weight Rating (GAWR) for the
front and rear axle. The GVWR and GAWR for
your vehicle are indicated on the
certification label which can be found on
the driver’s door B‑pillar.
For more information, see “Loading the
vehicle” ( Y page 130).
The handling characteristics of a fully
loaded vehicle depend greatly on the load
distribution. It is therefore recommended
to load the vehicle with the heaviest items
being placed towards the front of the
vehicle.
Please pay attention to and comply with the
following instructions when loading the
vehicle and transporting cargo:
R Always place items being carried
against seat backrests, and fasten them
as securely as possible.
R The heaviest portion of the cargo should
always be kept as low as possible against
seat backrests.
R Do not stack loads higher than the top
edge of the head restraints.
R Make sure no luggage/cargo items can get
above or next to the driver’s and/or
passenger seat into the passenger
compartment.
R Make sure luggage/cargo is properly
secured.
R Always use, if so equipped, cargo net*
when transporting cargo.
Do not carry any unnecessary weight in the
vehicle. This increases vehicle weight,
which results in increased energy
consumption. Useful features

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.

transmitters
Radio and telephone G
WARNING
Please do not forget that your primary
responsibility is to drive the vehicle
safely. Only operate the radio or
telephone 16
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 a distance 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
engine

is running. 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. Emission control
Certain engine systems serve to keep the
toxic components of the exhaust gases
within permissible legal limits.
These systems, of course, will function
properly only when maintained strictly
according to factory specifications.
Any adjustments to the engine should
therefore

be carried out only by qualified
smart center authorized technicians.
Engine adjustments should not be altered
in any way. Moreover, the specified service
jobs must be carried out regularly
according to smart servicing
requirements. For details refer to the
Maintenance Booklet. G
WARNING
Inhalation of exhaust gas is hazardous to
your health. All exhaust gas contains
carbon monoxide (CO), and inhaling it can
cause unconsciousness and lead to death.
Do not run the engine in confined areas
(such as a garage) which are not properly
ventilated. If you think that exhaust gas
fumes are entering the vehicle while
driving, have the cause determined and
corrected immediately. If you must drive
under these conditions, drive only with at
least one window fully open at all times.

WARNING
Do not exceed vehicle speed of 50 mph
(80 km/h). A tire sealant repair is not
designed to operate at higher speeds.
The sticker must be attached on the
instrument cluster where it will be easily
seen by the driver.
Vehicle handling characteristics of a tire
sealant repaired tire may change. Adapt
your driving accordingly.

WARNING
If tire inflation pressure has fallen below
130 kPa (1.3 bar, 19 psi) do not continue to
drive the vehicle.
Park your vehicle safely away from the
roadway and contact the nearest smart
center or call Roadside Assistance.
Have the damaged tire replaced.
X If the tire inflation pressure is at least
130

kPa (1.3 bar, 19 psi), inflate or deflate
the tire to correct tire inflation
pressure (see Tire and Loading
Information placard located on the
driver’s door B‑pillar). R
To increase the tire inflation
pressure: Switch on the electric air
pump.
R To decrease the tire inflation
pressure:

! The manufacturer is unable to
guarantee that all tire punctures can be
repaired with the tire repair kit, in
particular cuts or perforations larger
than

approximately 0.16 in (4 mm) or away
from the tire’s tread. The manufacturer
is not liable for damage sustained
through improper use of the tire repair
kit. G
WARNING
Follow recommended tire inflation
pressures.
Do not underinflate tires. Underinflated
tires wear excessively and/or unevenly,
adversely affect handling and fuel
economy, and are more likely to fail from
being overheated.
Do not overinflate tires. Overinflated
tires can adversely affect handling and
ride comfort, wear unevenly, increase
stopping distance, and result in sudden
deflation (blowout) because they are more
likely to become punctured or damaged by
road debris, potholes etc.
Do not overload the tires by exceeding the
specified load limit as indicated on the
