GWARNING
In the following situations, the tire seal-
ant is unable to provide sufficient break-
down assistance, as it is unable to seal the
tire properly:
Rthere are cuts or punctures in the tire
larger than those mentioned above.
Rthe wheel rim is damaged.
Ryou have driven at very low tire pressures
or on a flat tire.
There is a risk of an accident.
Do not drive the vehicle. Contact a quali-
fied specialist workshop.
GWARNING
The tire sealant is harmful and causes irri-
tation. It must not come into contact with
your skin, eyes or clothing or be swallowed.
Do not inhale TIREFIT fumes. Keep tire
sealant away from children. There is a risk
of injury.
If you come into contact with the tire seal-
ant, observe the following:

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.

>> Wheels and tires.
Z

!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
obtained at a qualified specialist workshop.
0043Recommended tire pressures
The Tire and Loading Information placard is
on the B-pillar on the driver's side
(
Ypage 185).
The Tire and Loading Information placard
contains the recommended tire pressures for
cold tires. The recommended tire pressures
are valid for the maximum permissible load
and up to the maximum permissible vehicle
speed.
The tire pressure table is on the inside of the
fuel filler flap.
180Tire pressure
>> Wheels and tires.

Use a suitable pressure gauge to check the
tire pressure. The outer appearance of a tire
does not permit any reliable conclusion
about the tire pressure. On vehicles equip-
ped with the electronic tire pressure moni-
tor, the tire pressure can be checked in the
on-board computer.
The tire temperature and pressure increase
when the vehicle is in motion. This is
dependent on the driving speed and the load.
Therefore, you should only correct tire pres-
sures when the tires are cold.
The tires are cold:
Rif the vehicle has been parked with the
tires out of direct sunlight for at least
three hours and
Rif the vehicle has not been driven further
than 1 mile (1.6 km)
The tire temperature changes depending on
the outside temperature, the vehicle speed
and the tire load. If the tire temperature
changes by 18 ‡(10 †), the tire pressure
changes by approximately 10 kPa (0.1 bar/
1.5 psi). Take this into account when checking
the pressure of warm tires. Only correct the
tire pressure if it is too low for the current
operating conditions. If you check the tire
pressure when the tires are warm, the result-
ing value will be higher than if the tires were
cold. This is normal. Do not reduce the tire
pressure to the value specified for cold
tires. The tire pressure would otherwise be
too low.
Observe the recommended tire pressures for
cold tires:
Ron the Tire and Loading Information plac-
ard on the B-pillar on the driver's side
Rin the tire pressure table in the fuel filler
flap (Ypage 98).
Underinflated or overinflated tires
GWARNING
Tires with pressure that is too low can
overheat and burst as a consequence. In
addition, they also suffer from excessive
and/or irregular wear, which can severely
impair the braking properties and the
driving characteristics. There is a risk of an accident.
Avoid tire pressures that are too low in all
the tires, including the spare wheel.
Underinflated tires
Underinflated tires may:
Roverheat, leading to tire defects
Radversely affect handling
Rwear excessively and/or unevenly
Rhave an adverse effect on fuel consumption
GWARNING
Tires with excessively high pressure can
burst because they are damaged more easily by road debris, potholes etc. In addition,
they also suffer from irregular wear, which
can severely impair the braking properties
and the driving characteristics. There is a
risk of an accident.
Avoid tire pressures that are too high in all
the tires, including the spare wheel.
Overinflated tires
Overinflated tires may:
Rincrease the braking distance
Radversely affect handling
Rwear excessively and/or unevenly
Rhave an adverse effect on ride comfort
Rbe more susceptible to damage
Maximum tire pressures
0043Example: maximum permissible tire
pressure
Never exceed the maximum permissible tire
inflation pressure. Always observe the rec-
ommended tire pressure for your vehicle when
adjusting the tire pressure (
Ypage 180).

(Ypage 126) and the indicator and warning
lamps in the instrument cluster in the "Tires" section (
Ypage 139).
Restarting the tire pressure monitor
When you restart the tire pressure monitor,
all existing warning messages are deleted
and the warning lamps go out. The monitor
uses the currently set tire pressures as the
reference values for monitoring. In most
cases, the tire pressure monitor will auto-
matically detect the new reference values
after you have changed the tire pressure.
However, you can also define reference values
manually as described here. The tire pres-
sure monitor then monitors the new tire pres-
sure values.
XSet the tire pressure to the value recom-
mended for the corresponding driving sit-
uation on the Tire and Loading Information
placard on the B-pillar on the driver's side
(
Ypage 180).
Additional tire pressure values for dif-
ferent loads can also be found on the tire
pressure table on the inside of the fuel
filler flap (
Ypage 180).
XMake sure that the tire pressure is correct on all four wheels.

checks whether the current tire pressures are within the specified range. The new
tire pressures are then accepted as refer-
ence values and monitored.
iIf the
Tire Pressure Monitor Restar‐tedmessage does not appear after approx-
imately 5 seconds, the restart was not suc-
cessful. If this occurs, repeat the restart.
If you wish to cancel the restart:

Loading the vehicle
Instruction labels for tires and loads
GWARNING
Overloaded tires can overheat, causing a
blowout. Overloaded tires can also impair
the steering and driving characteristics
and lead to brake failure. There is a risk of
accident.
Observe the load rating of the tires. The
load rating must be at least half of the GAWR
of your vehicle. Never overload the tires by exceeding the maximum load.
Two instruction labels on your vehicle show
the maximum possible load.
(1) The Tire and Loading Information plac- ard is on the B-pillar on the driver's
side. The Tire and Loading Information
placard shows the maximum permissible
number of occupants and the maximum
permissible vehicle load. It also con-

that weigh more than the replaced standard
parts and more than 5 lbs (2.3 kilograms).
These optional extras, such as high-perform-
ance brakes, level control, a roof rack or a
high-performance battery, are not included
in the curb weight and the weight of the
accessories.
TIN (Tire Identification Number)
This is a unique identifier which can be used
by a tire manufacturer to identify tires, for
example for a product recall, and thus iden-
tify the purchasers. The TIN is made up of the manufacturer's identity code, tire size, tire
type code and the manufacturing date.
Load bearing index
The load bearing index (also load index) is a
code that contains the maximum load bearing
capacity of a tire.
Traction
Traction is the result of friction between the
tires and the road surface.
Treadwear indicators

Changing a wheel
Flat tire
You can find information on what to do in the
event of a flat tire in the "Flat tire" section
(
Ypage 161).
Rotating the wheels
GWARNING
Never interchange the front and rear wheels
as they have different dimensions, e.g.
size, wheel offset etc. Otherwise, there
could be a negative effect on the road hold- ing and you could endanger yourself or oth-
ers.
!On vehicles equipped with a tire pressure
monitor, electronic components are loca-
ted in the wheel.
Tire-mounting tools should not be used
near the valve. This could damage the elec-
tronic components.
Only have tires changed at a qualified spe-
cialist workshop.
Various types of steel wheel can be fitted on
your vehicle. Some steel wheels have a red
mark in the hub cap area. The hub cap has to be
removed to see the red mark, see "Raising the
vehicle" in the "Wheel change" section
(
Ypage 197). When changing the wheels,
always fit wheels of the same type on all axles.
Always pay attention to the instructions and
safety notes when changing a wheel
(
Ypage 196).
The wear patterns on the front and rear tires
differ, depending on the operating condi-
tions. Front tires typically wear more on the
shoulders and the rear tires in the center.
Clean the contact surfaces of the wheel and
the brake disc thoroughly every time a wheel
is rotated. Check the tire pressure and reac-
tivate the tire pressure monitor if necessary.
