For this reason, always secure persons
under 5 ft (1.50 m) in height in suitable
restraint systems.
If a child younger than twelve years old and
under 5 ft (1.50 m) in height is traveling in the
vehicle:
Ralways secure the child in a child restraint
system suitable for this smart vehicle. The
child restraint system must be appropriate
to the age, weight and size of the child
Ralways observe the instructions and safety
notes on "Children in the vehicle"
(
Ypage 42) in addition to the child

GWARNING
The seat belts may not perform their inten- ded protective function if:
Rthey are damaged, modified, extremely
dirty, bleach or dyed
Rthe seat belt buckle is damaged or
extremely dirty
Rthe Emergency Tensioning Devices, belt
anchorages or inertia reels have been
modified
Seat belts may sustain non-visible damage
in an accident, e.g. due to glass splinters.
Modified or damaged seat belts may tear or
fail, e.g. in an accident. Modified Emer-
gency Tensioning Devices could acciden-
tally trigger or fail to deploy when neces-
sary. This poses an increased risk of injury
or even fatal injury.
Never modify the seat belts, Emergency
Tensioning Devices, belt anchorages or
inertia reels. Make sure that the seat belts
are undamaged, not worn out and clean. Fol-
lowing an accident, have the seat belts
checked immediately at a qualified spe-
cialist workshop.
Only use seat belts that have been approved
for your vehicle by smart.
Proper use of the seat belts
Pay attention to the safety notes about the
seat belt (Ypage 31).
All vehicle occupants must fasten the seat
belt correctly before setting off. Make sure
that all occupants are wearing their seat
belts correctly for the entire journey.
When fastening the seat belt, make sure that:
RThe seat belt tongue is inserted into the
belt buckle that belongs to the seat.
RThe seat belt is tightened across your body.
Avoid wearing bulky clothing, e.g. a winter coat.
RThe seat belt is not twisted.
Only then can the forces produced in the
event of an accident be evenly distributed
across the belt.
RThe shoulder section of the belt must always
be routed across the center of the shoulder.
The shoulder section of the belt should not come into contact with your neck and must
not be routed under the arm.
RThe lap belt must be taut and as low as pos-
sible over your lap.
The lap belt must always pass across your
hip joints and never across your stomach or
abdomen. Pregnant women must take par-
ticular care. If necessary, the lap belt canbe pushed down across the hip joints and
pulled tight using the shoulder section.
RThe seat belt is not routed over sharp,
pointed or fragile objects.
If these items are on or in your clothing,
e.g. eyeglasses, pens, keys, etc., stow theseitems in a more suitable location.
ROnly one person should use each seat belt at
any one time.
On no account should babies or children
travel sitting on the lap of another vehicle occupant. During an accident, they could be
crushed between the occupant and seat belt.
RObjects are not secured with a seat belt if
the seat belt is being used by one of the
vehicle’s occupants.

Starting at a speed of around 4 mph (7 km/h),
the distance warning function warns you if
you rapidly approach a vehicle in front. An
intermittent warning tone will then sound
and the 00BAdistance warning lamp will
light up in the instrument cluster.
XBrake immediately in order to increase the distance from the vehicle in front.
or
XTake evasive action, provided it is safe to
do so.
Due to the nature of the system, particularly
complicated but non-critical driving condi-
tions may also cause the system to display a
warning.
With the help of the radar sensor system, the
distance warning function can detect obsta-
cles that are in the path of your vehicle for an
extended period of time.
Up to a speed of around 45 mph (70 km/h), the
distance warning function can also react to
stationary obstacles, such as stopped or
parked vehicles.
ESP®(Electronic Stability Program)

tion (Ypage 47).
esp
®monitors driving stability and traction,
i.e. power transmission between the tires and the road surface.
If esp
®detects that the vehicle is deviating
from the direction desired by the driver, one
or more wheels are braked to stabilize the
vehicle. The engine output is also modified
to keep the vehicle on the desired course
within physical limits. esp

during braking.
ETS (Electronic Traction System)
iObserve the "Important safety notes" sec-
tion (Ypage 47).
ETS traction control is part of esp
®.
ETS brakes the drive wheels individually if
they spin. This enables you to pull away and
accelerate on slippery surfaces, for example if the road surface is slippery on one side. In
addition, more drive torque is transferred to
the wheel with traction.
Important safety notes
GWARNING
If ESP
®is malfunctioning, ESP®is unable to
stabilize the vehicle. Additionally, fur-
ther driving safety systems are deactiva-
ted. This increases the risk of skidding and
an accident.
Drive on carefully. Have ESP
®checked at a
qualified specialist workshop.
!If you test the parking brake using a brake
dynamometer, switch the ignition off.
Application of the brakes by ESP

GWarning
A flat tire severely impairs the driving,
steering and braking characteristics of
the vehicle. There is a risk of an accident.
do not drive with a flat tire. Immediately
replace the flat tire with your spare wheel,
or consult a qualified specialist workshop.
Accessories that are not approved for your
vehicle by smart or that are not being used
correctly can impair driving safety. Before purchasing and using non-approved
accessories, visit a qualified specialist
workshop and inquire about:
Rsuitability
Rlegal stipulations
Rfactory recommendations

Operation
Information on driving
RCheck the tire pressures when the vehicle
is heavily laden and, if necessary, adjust
before beginning your journey.
RWhile driving, pay attention to vibrations,
noises and unusual handling characteris-
tics, e.g. pulling to one side. This may
indicate that the wheels or tires are dam-
aged. If you suspect that a tire is defec-
tive, reduce your speed immediately. Stop
the vehicle as soon as possible to check the
wheels and tires for damage. Hidden tire
damage could also be causing the unusual
handling characteristics. If you find no
signs of damage, have the tires and wheels
checked at a qualified specialist work-
shop.
RWhen parking your vehicle, make sure that
the tires do not get deformed by the curb or
other obstacles. If it is necessary to drive
over curbs, speed humps or similar eleva-
tions, try to do so slowly and at an obtuse
angle. Otherwise, the tires, particularly
the sidewalls, may be damaged.

Regular checking of wheels and tires
GWARNING
Damaged tires can cause tire inflation
pressure loss. As a result, you could lose
control of your vehicle. There is a risk of
accident.
Check the tires regularly for signs of dam- age and replace any damaged tires imme-
diately.
Regularly check the wheels and tires of your
vehicle for damage, at least once a month, as
well as after driving on rough roads. Damaged
wheels can cause a loss of tire pressure. Pay
particular attention to damage such as:
Rcuts in the tires
Rpunctures in the tires
Rtears in the tires
Rbulges on tires
Rdeformation or severe corrosion on wheels
Regularly check the tire tread depth and the
condition of the tread across the whole width
of the tire (
Ypage 178). If necessary, turn the
front wheels to full lock in order to inspect
the inner side of the tire surface.
All wheels must have a valve cap to protect the
valve against dirt and moisture. Do not fit
anything onto the valve other than the stand-
ard valve cap or other valve caps approved for
your vehicle by smart. Do not use any other
valve caps or systems, e.g. tire pressure mon-
itoring systems.
Regularly check the pressure of all the tires
particularly prior to long trips. Adjust the
tire pressure as necessary (
Ypage 180).
The service life of tires depends, among
other things, on the following factors:
RDriving style
RTire pressure
RDistance covered
Notes on tire profile
GWARNING
Insufficient tire tread will reduce tire
traction. The tire is no longer able to dis-
sipate water. This means that on wet road
surfaces, the risk of hydroplaning increa-
ses, in particular where speed is not adap- ted to suit the driving conditions. There is
a risk of accident.
If the tire pressure is too high or too low,
tires may exhibit different levels of wear
at different locations on the tire tread.
Thus, you should regularly check the tread
depth and the condition of the tread across
the entire width of all tires.
Minimum tire tread depth for:
RSummer tires: 00CEin (3 mm)
RM+S tires: 00CFin (4 mm)
For safety reasons, replace the tires before
the legally prescribed limit for the mini-
mum tire tread depth is reached.
Indicator 0043shows which position the bar
marking (arrow) for tread wear is integrated
into the tire tread.
Treadwear indicators (TWI) are required by
law. Six indicators are positioned on the tire
tread. They are visible once a tread depth of
approximately 00CDin (1.6 mm) has been
reached. If this is the case, the tire is so worn
that it must be replaced.
Selecting, mounting and replacing
tires
ROnly mount tires and wheels of the same
type and make.
Exception: it is permissible to fit a dif-
ferent type or make in the event of a flat
tire.
ROnly mount tires of the correct size onto the
wheels.
178Operation
>> Wheels and tires.

RAfter fitting new tires, run them in at mod-
erate speeds for the first 60 miles (100 km),
as they only reach their full performance
after this distance.
RDo not drive with tires which have too little
tread depth, as this significantly reduces
the traction on wet roads (hydroplaning).
RReplace the tires after six years at the lat-
est, regardless of wear.
Winter operation
General notes
Have your vehicle winterproofed at a quali-
fied specialist workshop at the onset of win-
ter.
Observe the notes in the "Changing a wheel"
section (
Ypage 196).
Driving with summer tires
At temperatures below 45 ‡(+7 †), summer
tires lose elasticity and therefore traction
and braking power. Change the tires on your
vehicle to M+S tires. Using summer tires at
very cold temperatures could cause tears to
form, thereby damaging the tires perma-
nently. smart cannot accept responsibility
for this type of damage.
GWARNING
Damaged tires can cause tire inflation
pressure loss. As a result, you could lose
control of your vehicle. There is a risk of
accident.
Check the tires regularly for signs of dam- age and replace any damaged tires imme-
diately.
M+S tires
GWARNING
M+S tires with a tire tread depth of less
than 00CFin (4 mm) are not suitable for use in
winter and do not provide sufficient trac-
tion. There is a risk of an accident.
M+S tires with a tread depth of less than 00CF
in (4 mm) must be replaced immediately.
At temperatures below 45 ‡(+7 †) use winter
tires marked with M+S.
Only winter tires bearing the 004Dsnowflake
symbol in addition to the M+S marking pro-
vide the best possible grip in wintry road
conditions. Only these tires will allow driv-
ing safety systems such as ABS and ESP
®to
function optimally in winter. These tires
have been developed specifically for driving
in snow.
Use M+S tires of the same make and tread on
all wheels to maintain safe handling charac- teristics.
Always observe the maximum permissible
speed specified for the M+S tires you have
mounted. Therefore, only use tire types and
sizes approved for smart. Observe the tire
load rating and speed rating required for
smart.
Tires with a specified direction of rotation
have additional benefits, e.g. if there is a
risk of aquaplaning. These advantages can
only be gained if the tires are fitted corre-
sponding to the direction of rotation.
An arrow on the sidewall of the tire indicates
its correct direction of rotation.
When you have mounted the M+S tires:
XCheck the tire pressures (Ypage 180).
XVehicles for USA: restart the tire pressure
monitor (Ypage 185).
Snow chains
GWARNING
If snow chains are installed to the front
wheels, they may drag against the vehicle
body or chassis components. This could
cause damage to the vehicle or the tires.
There is a risk of an accident.
To avoid hazardous situations:
Rnever install snow chains to the front
wheels
Ralways install snow chains in pairs to the rear wheels.

!Vehicles with steel wheels:if you mount
snow chains on steel wheels, you may dam-
age the hub caps. Remove the hub caps from
the relevant wheels before mounting the
snow chains.
smart recommends that you only use snow
chains that have been specially approved for
smart. For more information, please contact
the smart center or a qualified specialist
workshop.
Bear in mind that snow chains are designed
for a certain wheel size. If you mount tires
that are larger or smaller than the original
tires, you will require new snow chains of the
correct size.
If you intend to mount snow chains, please
bear the following points in mind:
RSnow chains may not be mounted on all
wheel/tire combinations. Permissible
wheel-tire combinations (
Ypage 200).
ROnly use snow chains when driving on roads
completely covered by snow. Remove the
snow chains as soon as possible when you
come to a road that is not snow-covered.
RLocal regulations may restrict the use of
snow chains. Observe the appropriate reg-
ulations if you wish to mount snow chains.
Rdo not exceed the maximum permissible
speed of 30 mph (50 km/h).
Tire pressure
Tire pressure specifications
GWARNING
Underinflated or overinflated tires pose
the following risks:
Rthe tires may burst, especially as the
load and vehicle speed increase.
Rthe tires may wear excessively and/or
unevenly, which may greatly impair tire
traction.
Rthe driving characteristics, as well as
steering and braking, may be greatly
impaired.
There is a risk of an accident.
Follow recommended tire inflation pres-
sures and check the pressure of all the tires including the spare wheel:
Rmonthly, at least
Rif the load changes
Rbefore beginning a long journey
Runder different operating conditions,
e.g. off-road driving
If necessary, correct the tire pressure.
The specifications on the sample Tire and
Loading Information placard and tire pres-
sure tables are examples. Tire pressure spec-
ifications are vehicle-specific and may
deviate from the data shown here. The tire
pressure specifications that are valid for
your vehicle can be found on the Tire and
Loading Information placard and tire pres-
sure table on the vehicle.
The recommended tire pressures for the tires
mounted at the factory can be found on the
labels described here.
Further information on tire pressures can be
