Fuses
Important safety notes
GWARNING
If you manipulate or bridge a faulty fuse or if you replace it with a fuse with a higher
amperage, the electric cables could be
overloaded. This could result in a fire.
There is a risk of an accident and injury.
Always replace faulty fuses with the speci-
fied new fuses having the correct amper-
age.
!Only use fuses that have been approved for
smart vehicles and which have the correct
fuse rating for the system concerned. Oth-
erwise, components or systems could be
damaged.
The fuses in your vehicle serve to close down
faulty circuits. If a fuse blows, all the com-
ponents on the circuit and their functions
stop operating.
Blown fuses must be replaced with fuses of the
same rating, which you can recognize by the
color and value. The fuse ratings are listed in
the fuse allocation chart (
Ypage 175).
If a newly inserted fuse also blows, have the
cause traced and rectified at a qualified
specialist workshop, e.g. an authorized
Mercedes-Benz Center.
Before changing a fuse
XSecure the vehicle against rolling away
(Ypage 100).
XSwitch off all electrical consumers.
XTurn the key to position 0in the ignition
lock and remove it (Ypage 87). All indica-
tor lamps in the instrument cluster must be off.
The fuses are located in various fuse boxes:
RFuse box in the front area
RFuse box in the glove compartment
Fuse box in the front area
Pay attention to the "Important safety notes"
(Ypage 173).

!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.

>> Wheels and tires.

Tread
The part of the tire that comes into contact
with the road.
Bead
The tire bead ensures that the tire sits
securely on the wheel. There are several steel
wires in the bead to prevent the tire from
coming loose from the wheel rim.
Sidewall
The part of the tire between the tread and the
bead.
Weight of optional extras
The combined weight of those optional extras
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
Narrow bars (tread wear bars) that are dis-
tributed over the tire tread. If the tire tread
is level with the bars, the wear limit of 00CDin
(1.6 mm) has been reached.
Occupant distribution
The distribution of occupants in a vehicle at
their designated seating positions.
Total load limit
Nominal load and luggage load plus 68 kg
(150 lbs) multiplied by the number of seats in
the vehicle.
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.
196Changing a wheel
>> Wheels and tires.

Direction of rotation
Tires with a specified direction of rotation
have additional benefits, e.g. if there is a
risk of hydroplaning. 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.
Storing wheels
Store wheels that are not being used in a cool,
dry and preferably dark place. Protect the
tires from oil, grease, gasoline and diesel.

Raising the vehicle
GWARNING
If you do not position the jack correctly at
the appropriate jacking point of the vehi- cle, the jack could tip over with the vehicle
raised. There is a risk of injury.
Only position the jack at the appropriate
jacking point of the vehicle. The base of the jack must be positioned vertically,
directly under the jacking point of the
vehicle.

Observe the following when raising the vehi-
cle:
Rmake sure you have a suitable jack and
wheel wrench. If used incorrectly, the jack
could tip over with the vehicle raised.
For further information inquire at any
smart center.
Rthe jack is designed only to raise and hold
the vehicle for a short time while a wheel
is being changed. It is not suited for per-
forming maintenance work under the vehi-
cle.
Ravoid changing the wheel on uphill and
downhill slopes.
Rbefore raising the vehicle, secure it from
rolling away by applying the parking brake
and inserting wheel chocks. Never disen-
gage the parking brake while the vehicle is
raised.
Rthe jack must be placed on a firm, flat and
non-slip surface. On a loose surface, a
large, flat load-bearing underlay must be
used. On a slippery surface, a non-slip
underlay must be used, e.g. rubber mats.
Rdo not use wooden blocks or similar objects
as a jack underlay. Otherwise, the jack will
not be able to achieve its load-bearing
capacity due to the restricted height.
Rmake sure that the distance between the
underside of the tires and the ground does
not exceed 1.2 in (3 cm).
Rnever place your hands and feet under the
raised vehicle.
Rdo not lie under the vehicle.
Rdo not start the engine when the vehicle is
raised.
Rdo not open or close a door or the tailgate
while the vehicle is raised.
Rmake sure that no persons are present in the
vehicle when the vehicle is raised.
!The jack is designed exclusively for
jacking up the vehicle at the jacking
points. Otherwise, your vehicle could be
damaged.

Vehicle electronics
Retrofitting two-way radios and
mobile phones (RF transmitters)
GWARNING
The electromagnetic radiation from modi-
fied or incorrectly retrofitted RF-trans-
mitters can interfere with the vehicle
electronics. This can compromise the
operational safety of the vehicle. There is
a risk of an accident.
You should have all work to electrical and
electronic equipment carried out at a
qualified specialist workshop.
GWARNING
The electromagnetic radiation from incor-
rectly operated RF transmitters can inter-
fere with the vehicle electronics, for
example:
Rif the RF transmitter is not connected
with an exterior antenna
Rthe exterior antenna has been installed
incorrectly or is not a low-reflection
type
This can compromise the operational safety
of the vehicle. There is a risk of an acci-
dent.
Have the low-reflection exterior antenna
mounted at a qualified specialist work-
shop. When operating RF transmitters in
the vehicle, always connect them with the
low-reflection exterior antenna.
!The operating permit may be invalidated
if the instructions for installation and use of RF transmitters are not observed.
In particular, the following conditions
must be complied with:
Ronly approved wavebands may be used.
Rcompliance with the maximum permissi-
ble output in these wavebands is
required.
Ronly approved antenna positions may be
used.
Excessive levels of electromagnetic radia-
tion may cause damage to your health and the
health of others. Using an exterior antenna
takes into account current scientific discus-
sions relating to the possible health hazards
that may result from electromagnetic fields.
