The remote control has an operating
range
of approximately 50 ft (15 meters).
This can fluctuate greatly as a
consequence of local conditions
(reflective or absorbing objects) and
interference emitted by other radio
transmission systems. Similarly, the
operating range fluctuates in line with
the direction from which the remote

To prevent theft, however, it is advisable
to only unlock the vehicle when you are

Vehicles
with rain-light sensor*: When you

suitable wiping interval depending on the
wetness of the sensor surface.
! Vehicles with rain-light sensor*:
Do not leave windshield wipers in
intermittent setting when the vehicle is
taken to an automatic car wash or during
windshield cleaning. Windshield wipers
will operate in the presence of water
sprayed on the windshield, and
windshield wipers may be damaged as a
result.
! Vehicles with rain-light sensor*:
If you have set intermittent wiping, dirt
on the surface of the sensor or optical
effects may cause the windshield wipers
to wipe in an undesired fashion. This
could then damage the windshield wiper
blades or scratch the windshield. You
should therefore switch off the
windshield wipers when weather
conditions are dry. X

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
Tire and Loading Information placard on
the
driver’s door B‑pillar. Overloading the
tires can overheat them, possibly causing
a blowout. Overloading the tires can also
result in handling or steering problems, or
brake failure.
Check the tire inflation pressure at least
once a month.
Check and adjust the tire inflation
pressure when the tires are cold
(Y page 125).
Checking tire inflation pressure
manually Follow the steps below to achieve correct
tire inflation pressure:
X
Remove the cap from the valve on one tire.
X Firmly press a tire gauge onto the valve.
X Read the tire inflation pressure on tire
gauge and check against the
recommended tire inflation pressure on
the Tire and Loading Information
placard on the driver’s door B‑pillar
(Y page 130). If necessary, add air to
achieve the recommended tire inflation
pressure.
X If you have overfilled the tire, release
tire inflation pressure by pushing the
metal

stem of the valve with e.g. a tip of
a pen. Then recheck the tire inflation
pressure with the tire gauge.
X Install the valve cap.
X Repeat this procedure for each tire.
Tire Pressure Monitoring System (TPMS)* Your vehicle may be equipped with a Tire
Pressure
Monitoring System (TPMS). It monitors the tire inflation pressure in
all

four tires. A warning is issued to alert
you to a decrease in pressure in one or more
of the tires.
The Tire Pressure Monitoring System
(TPMS) is equipped with a combination low
tire pressure/TPMS malfunction telltale in
the instrument cluster. Depending on how
the telltale illuminates, it indicates a low
tire pressure condition or a malfunction in
the TPMS system itself:
R If the telltale illuminates continuously,
one or more of your tires is significantly
underinflated. There is no malfunction
in the TPMS.
R If the telltale flashes for 60 seconds and
then stays illuminated, the TPMS system
itself is not operating properly.
The TPMS only functions on wheels that are
equipped with the proper electronic
sensors. G
WARNING
The TPMS does not indicate a warning for
wrongly selected inflation pressures.
Always adjust tire inflation pressure
according to the Tire and Loading
Information placard on the driver’s door
B‑pillar.
The

TPMS is not able to issue a warning due
to a sudden dramatic loss of pressure (e.g.
tire blowout caused by a foreign object). In
this case bring the vehicle to a halt by
carefully applying the brakes and avoiding
abrupt steering maneuvers. G
WARNING
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. Tires and wheels

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:
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.
R Never 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

WARNING
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. G
WARNING
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. 146
