Indicated temperatures just above the
freezing point do not guarantee that the
road surface is free of ice. The road may
still be icy, especially in wooded areas or
on bridges. Your vehicle could start to skid
if you do not adjust your driving style
accordingly.
Therefore, always adjust your driving style
to the prevailing road and weather
conditions.
Freeze warning (Canada vehicles only)
When the outside temperature falls below
3 ¥ , the multifunction display makes you
aware of the fact that the road may be icy.
An additional freeze warning, i.e. an ice
crystal symbol, in the multifunction
display flashes. After 60 seconds, the
freeze warning stops flashing but
continues to be displayed. When the
outside temperature rises above 3 ¥, the
freeze warning goes out.
Fuel level display
Example illustration (U.S. vehicles)
The fuel level display shows the tank’s fuel
level with the aid of eight segments. The
number of dark segments indicates the fuel
level in the tank. If all eight segments are
dark, the tank is full.
You are driving on reserve fuel if there are
no more than 1.0 US gal (3.78 l) of fuel in the
tank.
If this occurs,
R the fuel pump symbol in the fuel level
display flashes
R the reserve fuel indicator shows the fuel
level in the tank in 0.1 US gal (0.5 l)
increments

approved engine oils and oil filters
contact an authorized smart center.
Using engine oils and oil filters of
specification other than those expressly
required for the Maintenance System, or
changing of oil and oil filter at change
intervals longer than those called for by
the Maintenance System will result in
engine or emission control system
damage not covered by the smart Limited
Warranty.
GWarning!
When adding engine oil, always use a funnel
to avoid spilling oil on any hot parts such
as the catalytic converter or exhaust
system.
If this should happen, however, the engine
must be thoroughly cleaned before you
continue your trip. The engine oil could
otherwise ignite.

The windshield washer reservoir is located
in the front compartment on the driver’s
side.GWarning!
Windshield washer concentrate is highly
flammable. Fire, naked flames and smoking
are prohibited when windshield washer
concentrate is being handled.
XUse a windshield washer concentrate

temperatures above freezing point.XUse a windshield washer concentrate
labeled for winter and water for
temperatures below freezing point.
! Always use a windshield washer
concentrate labeled for winter where
temperatures may fall below freezing
point. Failure to do so could result in
damage to the washer system/reservoir.
XPremix the windshield washer fluid in a
suitable container.

reservoir.XRemount the service flap and close it
( Y page 110).Brake fluidGWarning!
During vehicle operation, the boiling
point of the brake fluid is continuously
reduced through the absorption of moisture
from the atmosphere. Under extremely
strenuous operating conditions, this
moisture content can lead to the formation
of bubbles in the system, thus reducing the
system’s efficiency.
Therefore, the brake fluid must be replaced
regularly. Refer to your vehicle’s
Maintenance Booklet for replacement
interval.
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.
! If you find that the brake fluid in the
brake fluid reservoir has fallen to the
minimum mark or below, have the brake
system checked for brake pad thickness
and leaks immediately. Contact an
authorized smart center immediately. Do
not add brake fluid as this will not solve
the problem.
XRemove the service flap and insert it on
the front of the vehicle ( Y page 110).
The brake fluid reservoir is located in the
front compartment on the passenger side.

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 alternatetires 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.
i If a condition causing the TPMS to
malfunction develops, it may take up to
10 minutes for the system to signal a
malfunction using the TPMS telltale
flashing and illumination sequence.
The telltale extinguishes after a few
minutes driving if the malfunction has
been corrected.
i Operating radio transmission
equipment (e.g. wireless headsets, two-
way radios) in or near the vehicle could
cause the TPMS to malfunction.

iFor illustration purposes only. Actual
data on tires are specific to each vehicle
and may vary from data shown in above
illustration.
The maximum tire load 0046 is the maximum
weight the tires are designed to support.

cargo load capacities ( Y page 121).
Direction of rotation
Unidirectional tires offer added
advantages, such as better hydroplaning
performance. To benefit, however, you must
make sure the tires rotate in the direction
specified.
An arrow on the sidewall indicates the
intended direction of rotation (spinning)
of the tire.
Tire care and maintenance
GWarning!
Regularly check the tires for damage.
Damaged tires can cause tire inflation
pressure loss. As a result, you could lose
control of your vehicle.
Worn, old tires can cause accidents. If the
tire tread is badly worn, or if the tires have
sustained damage, replace them.
Check the tire inflation pressure at least
once a month. For more information on
checking tire inflation pressure, see
“Recommended tire inflation pressure”
( Y page 115).
Tire inspection
Every time you check the tire inflation
pressure, you should also inspect your
tires for the following
R excessive treadwear ( Y page 123)
R cord or fabric showing through the tire’s
rubber
R bumps, bulges, cuts, cracks or splits in
the tread or side of the tire
Replace the tire if you find any of the above
conditions.
Life of tire
GWarning!
Tires should be replaced after 6 years,
regardless of the remaining tread.
The service life of a tire is dependent upon
varying factors including but not limited
to
R driving style
R tire inflation pressure
R distance driven
Tread depth
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.
Tires and wheels123>> Operation.451_AKB; 3; 22, en-USd2ureepe,Version: 2.11.8.12009-07-27T09:36:34+02:00 - Seite 123Z

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.
