2010 SMART FORTWO COUPE tire pressure

GWarning!
If other than recommended brake pads are
installed, or other than recommended brake
fluid is used, the braking properties of the
vehicle can be degraded to an extent that
safe braking is substantially impaired.
This could result in an accident.
GWarning!
New brake pads will not achieve their
optimal braking effect until after several
hundred miles (kilometers). This means
that you must compensate for the reduced
braking effect by pressing harder on the
brake pedal and adapt your driving style
accordingly. The same applies after brake
pads or brake discs have been changed.
Drive sensibly - save fuel
Fuel consumption, to a great extent,
depends on driving habits and operating
conditions.
To save fuel you should:
R Shift gears in a timely manner.
R Avoid frequent acceleration and
deceleration.
R Keep tires at the recommended inflation
pressures.
R Remove carriers* when not in use.
R Remove unnecessary loads.
R Allow engine to warm up under low load
use.
R Have all maintenance work performed at
the intervals specified in the
Maintenance Booklet and as required by
the Maintenance System. Contact an
authorized smart center.
Fuel consumption is also increased by
driving in cold weather, in stop-and-go
traffic, on short trips, and in hilly areas.
Catalytic converter
Your smart is equipped with monolithic-
type catalytic converter, an important
element in conjunction with the oxygen
sensors to achieve substantial control of
the pollutants in the exhaust emissions.
Keep your vehicle in proper operating
condition by following our recommended
maintenance instructions as outlined in
your Maintenance Booklet.GWarning!
The catalytic converter can become very
hot. Coming into contact with the catalytic
converter could result in burns.
Note the following:
R Do not remove the protective heat guards.
R Do not apply any underseal.
R As with any vehicle, do not idle, park, or
operate this vehicle in areas where
combustible materials such as grass,
hay, or leaves can come into contact with
the hot exhaust system, as these
materials could be ignited and cause a
vehicle fire.
! To prevent damage to the catalytic
converter, only use premium unleaded
gasoline in this vehicle.
Any noticeable irregularities in engine
operation should be repaired promptly.
Otherwise, excessive unburned fuel may
reach the catalytic 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.
R Fill up only with premium unleaded
gasoline. Even small quantities of
leaded gasoline can damage the catalytic
converter.
R Make sure you adhere to the prescribed
service intervals.

RNever run the fuel tank empty.
R If the engine starts to misfire, bring the
vehicle to an immediate standstill
without endangering traffic.
R If the engine fails to start the first time,
you should not try to start it any more
than three times in succession.
R Do not try to start for more than four
seconds at a time.
Tires
GWarning!
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 underbody
for possible damage. If the vehicle or tires
appear unsafe, have the vehicle towed to the
nearest smart center or tire dealer for
repairs.
Treadwear indicators (TWI) are required by
law. These indicators are located in six
places on the tread circumference and
become visible at a tread depth of
approximately 1
/ 16 in (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.
GWarning!
Although the applicable federal motor
vehicle safety laws consider a tire to be
worn when the treadwear indicators (TWI)
become visible at approximately 1
/ 16 in
(1.6 mm), we recommend that you do not allow
your tires to wear down to that level. As
tread depth approaches 1
/ 8 in (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.
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
temperatures).GWarning!
Do not drive with a flat tire. A flat tire will
affect your ability to steer or brake and may
cause you to lose control of the vehicle.
Continued driving with a flat tire or
driving at high speed with a flat tire will
cause excessive heat build-up and possibly
a fire.
For more information, see “Tires and
wheels” ( Y page 114).
Hydroplaning
Depending on the depth of the water layer
on the road, hydroplaning may occur
resulting in a loss of control, even at low
speeds and with new tires. Reduce vehicle
speed, avoid track grooves in the road and
apply brakes cautiously when it is raining.
Tire traction
The safe speed on a wet, snow covered or icy
road is always lower than on a dry road.
You should pay particular attention to the
condition of the road whenever the outside
temperatures are close to the freezing
point.
GWarning!
If ice has formed on the road, tire traction
will be substantially reduced. Under such
weather conditions, drive, steer and brake
with extreme caution.

GWarning!
Each tire should be checked monthly when cold and inflated to the inflation pressure
recommended by the vehicle manufacturer on the Tire and Loading Information placard. If
your vehicle has tires of a different size than the size indicated on the Tire and Loading
Information placard, you should determine the proper tire inflation pressure for those
tires.
As an added safety feature, your vehicle has been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire pressure telltale when one or more of your tires
is significantly underinflated.
Accordingly, when the low tire pressure telltale illuminates, you should stop and check your
tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly
underinflated tire causes the tire to overheat and can lead to tire failure.
Underinflation also reduces fuel efficiency and tire tread life, and may affect the vehicle’s
handling and stopping ability. Please note that the TPMS is not a substitute for proper tire
maintenance, and it is the driver’s responsibility to maintain correct tire pressure, even
if underinflation has not reached the level to trigger illumination of the TPMS low tire
pressure telltale.
Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when
the system is not operating properly. The TPMS malfunction indicator is combined with the
low tire pressure telltale. When the system detects a malfunction, the telltale will flash for
approximately 1 minute and then remain continuously illuminated.

This sequence will continue upon subsequent vehicle start-ups as long as the malfunction
exists. When the malfunction indicator is illuminated, the system may not be able to detect
or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of reasons, including the installation of
incompatible replacement or alternate tires or wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the TPMS malfunction telltale after replacing one
or more tires or wheels on your vehicle to ensure that the replacement or alternate tires
and wheels allow the TPMS to continue to function properly.

Using the tire repair kit
! Depending on the type of damage on the
tire, the tire sealant could damage the
sensor of the Tire Pressure Monitoring
System (TPMS)*. Such damage is not
covered by the smart Limited Warranty.
When having the damaged tire replaced,
also have the TPMS sensors* checked for
proper function. When the sensor is
damaged, the TPMS* will not function
properly. The sensor must then be
replaced at an authorized smart center as
soon as possible.

The tire repair kit can be used to seal
punctures of up to approximately 0.16 in
(4 mm) on the tire tread.
The tire repair kit enables you to drive on
the sealed tire to the nearest authorized
smart center.XYou should have the sealed tire replaced
at an authorized smart center.GWarning!
Take care not to allow the contents of the
tire sealant to come in contact with hair,
eyes or clothing. The tire sealant is
harmful if inhaled, swallowed or absorbed
through the skin - causes skin, eye and
respiratory irritation. Wear gloves while
using this product if they are available.
Any contact with eyes or skin should be
flushed immediately with plenty of water.
If clothing comes in contact with the tire
sealant, change clothing as soon as
possible.
