G
Warning!
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.
G
Warning!
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:
Shift gears in a timely manner.
R
Avoid frequent acceleration and
R
deceleration.
Keep tires at the recommended inflation
R
pressures.
Remove carriers* when not in use.
R
Remove unnecessary loads.
R
Allow engine to warm up under low load
R
use.
Have all maintenance work performed at
R
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.
G
Warning!
The catalytic converter can become very
hot. Coming into contact with the catalytic
converter could result in burns.
Note the following:
Do not remove the protective heat guards.
R
Do not apply any underseal.
R
As with any vehicle, do not idle, park, or
R
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.
Fill up only with premium unleaded
R
gasoline. Even small quantities of
leaded gasoline can damage the catalytic
converter.
Make sure you adhere to the prescribed
R
service intervals.
