WARNING
When operating the heating or air
conditioning with climate control*, the
air that enters the passenger compartment
through

the air vents can be very hot or very
cold (depending on the set temperature).
This may cause burns or frostbite on
unprotected skin in the immediate area of
the air vents. Always keep sufficient
distance between unprotected parts of the
body and the air vents. If necessary, use the
air distribution control to direct the air
to air vents in the vehicle interior that are
not in the immediate area of unprotected
skin.
To make sure the heating or air
conditioning with climate control* works
properly, please observe the following:
R Keep the air intake grill free from
deposits, e.g. ice or snow, to ensure that104

WARNING
Never drive with iced up or fogged
windows. Visibility will be significantly
impaired. Impaired visibility could
endanger yourself and others. This may
prevent you from observing the traffic
conditions, thereby causing an accident.
The

best defrosting of windows is achieved
if the ice is completely removed from the
windows manually with an ice scraper
before starting the engine.

The
rear window defroster serves to de-ice
the rear window quickly and clear the view
if the rear window is fogged.
The rear window defroster uses a large
amount of power. To keep battery drain to a
minimum, switch off the rear window
defroster as soon as the rear window is
clear. The rear window defroster is
automatically deactivated after
approximately 10 minutes of operation. X

Auxiliary power outlet
The auxiliary power outlet supplies power
to the following electrical accessories
when the key is turned to starter switch
position 1:
R the cigarette lighter*, available in
conjunction with the ashtray*
R the electric air pump, available in
conjunction with the tire repair kit*
R other consumers which operate up to a
maximum of
60 W
! The auxiliary power outlet can
accommodate 12V DC electrical
accessories designed for use with the
standard “cigarette lighter” plug type.
Keep in mind, however, that connecting
accessories to the auxiliary power outlet
(for example extensive connecting and
disconnecting, or using plugs that do not
fit properly) can damage the auxiliary
power outlet. With the auxiliary power
outlet damaged, the cigarette lighter*
may no longer be able to be placed in the
heating (pushed-in) position, or may pop
out before it is hot enough.
The auxiliary power outlet is located in the
lower center console. Auxiliary power outlet

important to keep in mind that a
considerably higher degree of effort is
necessary to brake and steer the vehicle.
Adapt your driving accordingly.
Brakes
G
WARNING
Make sure not to endanger any other road
users when carrying out braking
maneuvers.
Refer to the description of the hydraulic
brake assistant
(Y page 48).
! Because the ESP ®
operates
automatically, the engine must be turned
off (ignition switched off) when the
parking brake is being tested on a brake
test dynamometer. Active braking action
through the ESP ®
may otherwise seriously
damage the brake system which is not
covered by the smart Limited Warranty.
Brake pad wear or a leak in the brake system
may be the reason for low brake fluid level
in the brake fluid reservoir.
The brake fluid level in the brake fluid
reservoir may be too low if the brake
warning lamp in the instrument cluster
comes on (Y page 22) although the parking
brake is released.
Have the brake system inspected
immediately. Contact an authorized smart
center.
All checks and service work on the brake
system should be carried out by qualified
technicians only. Contact an authorized
smart center.
Only install brake pads and use brake fluid
recommended by smart.
Inclines !
When driving down long and steep
grades,

relieve the load on the brakes by
shifting into a lower gear to use the engine’s braking power. This helps
prevent overheating of the brakes and
reduces brake pad wear.
When

using the engine’s braking power, a
drive wheel may not spin for an extended
period of time, e.g. on slippery road
surfaces. This may cause serious damage
to the drive- train which is not covered
by the smart Limited Warranty.
High and low stresses G
WARNING
Resting your foot on the brake pedal will
cause excessive and premature wear of the
brake pads.
It can also result in the brakes
overheating, thereby significantly
reducing their effectiveness and your
ability to stop the vehicle in sufficient
time to avoid an accident.
After

hard braking, it is advisable to drive
on for some time, rather than immediately
park, so that the air stream will cool down
the brakes faster.
If your brake system is normally only
subjected to moderate loads, you should
occasionally test the effectiveness of the
brakes by applying above-normal braking
pressure at higher speeds. This will also
enhance the grip of the brake pads. G
WARNING
Make sure not to endanger any other road
users when carrying out these braking
maneuvers.
Wet road surface G
WARNING
After driving in heavy rain for some time
without applying the brakes or through
water

deep enough to wet brake components,
the first braking action may be somewhat
reduced and increased pedal pressure may
be necessary to obtain expected braking 144
Driving instructions
>> Operation.

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
G
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
