2011 SMART FORTWO COUPE weight

Always follow the recommended tire
inflation pressure ( Y page 127) for proper
tire inflation.
Loading the vehicle
Two labels on your vehicle show how much
weight it may properly carry.
1)The Tire and Loading Information
placard can be found on the driver’s
door B‑pillar. This placard tells you
important information about the
number of people that can be in the
vehicle and the total weight that can be
carried in the vehicle. It also contains
information on the proper size and
recommended tire inflation pressures
for the original equipment tires on
your vehicle.2)The certification label, also found on
the driver’s door B‑pillar, tells you
about the gross weight capacity of your
vehicle, called the Gross Vehicle
Weight Rating (GVWR). The GVWR
includes the weight of the vehicle, all
occupants, fuel and cargo. The
certification label also tells you about
the front and rear axle weight capacity,
called the Gross Axle Weight Rating
(GAWR). The GAWR is the total allowable
weight that can be carried by a single
axle (front or rear). Never exceed the
GVWR or GAWR for either the front axle
or rear axle.0046 Driver’s door B‑pillarFollowing is a discussion on how to work
with the information contained on the Tire
and Loading Information placard with
regards to loading your vehicle.
Tire and Loading InformationGWarning!
Do not overload the tires by exceeding the
specified load limit as indicated on the
Tire and Loading Information placard on
the driver’s door B‑pillar. Overloading the
tires can overheat them, possibly causing
a blowout. Overloading the tires can also
result in handling or steering problems, or
brake failure.

The combined weight of all occupants and
cargo/luggage should never exceed the
weight referenced in that statement.
Seating capacity
The seating capacity gives you important
information on the number of occupants
that can be in the vehicle. The Tire and
Loading Information placard showing
seating capacity 0046 is located on the
driver’s door B‑pillar ( Y page 132).

Steps for determining correct load limit
The following steps have been developed as required of all manufacturers under Title 49,
Code of U.S. Federal Regulations, Part 575 pursuant to the “National Traffic and Motor
Vehicle Safety Act of 1966”.XStep 1: Locate the statement “The combined weight of occupants and cargo should never
exceed XXXX kg or XXXX lbs.” on your vehicle’s Tire and Loading Information placard.XStep 2: Determine the combined weight of the driver and passenger that will be riding
in your vehicle.XStep 3: Subtract the combined weight of the driver and passenger from XXXX kilograms
or XXXX lbs.XStep 4: The resulting figure equals the available amount of cargo and luggage load
capacity. For example, if the “XXXX” amount equals 540 lbs and there will be one 150 lbs
passenger in your vehicle, the amount of available cargo and luggage load capacity is
390 lbs (540 lbs - 150 lbs = 390 lbs).XStep 5: Determine the combined weight of luggage and cargo being loaded on the
vehicle. That weight may not safely exceed the available cargo and luggage load
capacity calculated in step 4.
i The maximum cargo compartment load is 110 lbs (50 kg).
The following table shows examples on how to calculate total and cargo load capacities
with varying seating configurations and number and size of occupants. The following
examples use a load limit of 540 lbs. This is for illustration purposes only . Make sure
you are using the actual load limit for your vehicle stated on the vehicle’s Tire and
Loading Information placard ( Y page 132).

available.

Certification label
Even after careful determination of the
combined weight of all occupants and cargo
as to not exceed the permissible load
limit, you must make sure your vehicle
never exceeds the Gross Vehicle Weight
Rating (GVWR) and the Gross Axle Weight
Rating (GAWR) for either the front or rear
axle. You can obtain the GVWR and GAWR
from the certification label. The
certification label can be found on the
driver’s door B‑pillar, see “Technical
data” ( Y page 214).
Gross Vehicle Weight Rating (GVWR) means:
The total weight of the vehicle, all
occupants, and all cargo must never exceed
the GVWR.
Gross Axle Weight Rating (GAWR) means:
The total allowable weight that can be
carried by a single axle (front or rear).
To assure that your vehicle does not exceed
the maximum permissible weight limits
(GVWR and GAWR for front and rear axle),
have the loaded vehicle (including driver,
passenger, and all cargo) weighed on a
suitable commercial scale.
Maximum tire load
GWarning!
Do not overload the tires by exceeding the
specified load limit as indicated on the
Tire and Loading Information placard on
the driver’s door B‑pillar. Overloading the
tires can overheat them, possibly causing
a blowout. Overloading the tires can also
result in handling or steering problems, or
brake failure.
i For 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 134).
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.

Vehicle maximum load on the tire
Load on an individual tire that is
determined by distributing to each axle
its share of the maximum loaded vehicle
weight and dividing it by two.
Winter driving
Before the onset of winter, have your
vehicle winterized at an authorized smart
center. This service includes:
R Check of anticorrosion and antifreeze
concentration.
R Addition of washer concentrate to the
water of the windshield/rear window.
Use a windshield washer concentrate
labeled for winter which is formulated
for temperatures below freezing point
( Y page 222).
R Battery test. Battery capacity drops with
decreasing ambient temperature. A well
charged battery helps to make sure the
engine can be started, even at low
ambient temperatures.
R Tire change.
Winter tires
GWarning!
Winter tires with a tread depth of less
than 1
/ 6 in (4 mm) must be replaced. They
are no longer suitable for winter
operation.
Always use winter tires at temperatures
below 45 ¦ (7¥ ) and whenever wintry road
conditions prevail. Not all M+S rated tires
provide special winter performance. Make
sure the tires you use show the mountain/
snowflake marking 004D on the tire
sidewall. These tires meet specific snow
traction performance requirements of the
Rubber Manufacturers Association (RMA)
and the Rubber Association of Canada (RAC)
and have been designed specifically for
use in snow conditions. Use of winter tires
is the only way to achieve the maximum
effectiveness of the ABS and ESP ®
in winter
operation.
For safe handling, make sure all mounted
winter tires are of the same make and have
the same tread design.
For information on winter tires for your
vehicle model, see the "Technical data"
section ( Y page 217).
Always observe the speed rating of the
winter tires installed on your vehicle. If
the maximum speed for which your tires are
rated is below the speed rating of your
vehicle, you must place a notice to this
effect where it will be seen by the driver.
Such notices are available at your tire
dealer or any authorized smart center.
Snow chains*
! Remember that snow chains must always
be compatible with the tire sizes of a
vehicle. Snow chains that are approved
by smart are only permitted for the
following tire size:
175/55 R15 on the rear axle.
For safety reasons, smart recommends
that you only use snow chains that have
been approved by smart.
Information on this is available from any
smart center.
Please refer to the separate operating
instructions for detailed information on
mounting the snow chains.
Snow chains should only be driven on
snow-covered roads at speeds not to
exceed 30 mph (50 km/h). Remove chains
as soon as possible when driving on roads
without snow.
