load capacity SMART FORTWO COUPE ELECTRIC DRIVE 2015 Owners Manual

After driving a few minutes the system
verifies that the current tire inflation
pressures are within the system’s speci-
fied range. Afterwards the current tire
inflation pressures are accepted as refer-
ence pressures and then monitored. Maximum tire inflation pressure
G
WARNING
Never exceed the max. tire inflation pres- sure. Follow recommended tire inflation
pressures.
Do not underinflate tires. Underinflated
tires wear excessively and/or unevenly,
adversely affect handling and energy con-
sumption, and are more likely to fail from
being overheated.
Do not overinflate tires. Overinflated
tires can adversely affect handling and
ride comfort, wear unevenly, increase
stopping distance, and result in sudden
deflation (blowout) because they are more
likely to become punctured or damaged by
road debris, potholes etc. i
For illustration purposes only. Actual
data on tires are specific to each vehicle and may vary from data shown in above
illustration.
This is the maximum permissible tire
inflation pressure :for the tire.
Always follow the recommended tire infla-
tion pressure (Y page 128) 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 plac- ard can be found on the driver’s door
B‑pillar. This placard tells you impor- tant 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 informa-
tion on the proper size and recommen-
ded tire inflation pressures for the
original equipment tires on your vehi-
cle.
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, automotive fluids 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 car-
ried by a single axle (front or rear).
Never exceed the GVWR or GAWR for
either the front axle or rear axle. :

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.
Tire and Loading Information placard
i Data shown on Tire and Loading Infor-
mation placard example are for illus-
tration purposes only. Load limit data
are specific to each vehicle and may vary
from data shown in the following illus-
tration. Refer to Tire and Loading Infor-
mation placard on vehicle for actual data specific to your vehicle. The Tire and Loading Information placard
showing load limit information :is loca-
ted on the driver’s door B‑pillar
(Y page 133).
X Locate the statement “The combined
weight of occupants and cargo should
never exceed XXXX kg or XXXX lbs.” on the
Tire and Loading Information placard.
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 :is located on the
driver’s door B‑pillar (Y page 133).
i Data shown on Tire and Loading Infor-
mation placard example are for illus-
tration purposes only. Seating capacity
data are specific to each vehicle and may
vary from data shown in the following
illustration. Refer to Tire and Loading
Information placard on vehicle for
actual data specific to your vehicle.
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”.
X Step 1: Locate the statement “The com-
bined weight of occupants and cargo
should never exceed XXXX kg or
XXXX lbs.” on your vehicle’s Tire and
Loading Information placard.
X Step 2: Determine the combined weight of
the driver and passenger that will be
riding in your vehicle.
X Step 3: Subtract the combined weight of
the driver and passenger from XXXX kilo- grams or XXXX lbs.
X Step 4: The resulting figure equals the
available amount of cargo and luggage 134

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).
X Step 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 capaci-
ties with varying seating configurations
and number and size of occupants. The fol- lowing 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 vehi-
cle’s Tire and Loading Information placard
(Y page 134).
The higher the weight of all occupants, the
less cargo and luggage load capacity is
available. Tires and wheels

Rim A metal support for a tire or a tire and tube
assembly upon which the tire beads are
seated.
Sidewall The portion of a tire between the tread and
the bead. TIN (Tire Identification Number) Unique identifier which facilitates
efforts by tire manufacturers to notify
purchasers in recall situations or other
safety matters concerning tires and gives
purchasers the means to easily identify
such tires. The TIN is comprised of “Man-
ufacturer’s identification mark”, “Tire
size”, “Tire type code” and “Date of manu-
facture”.
Tire load rating Numerical code associated with the maxi-
mum load a tire can support.
Tire ply composition and material used This indicates the number of plies or the
number of layers of rubber-coated fabric
in the tire tread and sidewall. Tire manu-
facturers also must indicate the ply mate-
rials in the tire and sidewall, which
include steel, nylon, polyester, and others.

Treadwear indicators
Narrow bands, sometimes called “wear
bars” that show across the tread of a tire
when only 1
/ 16 in (1.6 mm) of tread remains.
Uniform Tire Quality Grading Standards A tire information system that provides
consumers with ratings for a tire’s trac-
tion, temperature and treadwear. Ratings
are determined by tire manufacturers
using U.S. government testing procedures.
The ratings are molded into the sidewall of the tire.
Vehicle maximum load on the tire Load on an individual tire that is deter-
mined 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 vehi- cle winterized at an authorized electric
drive 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 218).
R 12 V battery test. The capacity of the
12 V battery test drops with decreasing
ambient temperature.
R Tire change. Winter tires

WARNING
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 ion the tire side-
wall. These tires meet specific snow trac-
tion performance requirements of the Rub- ber 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 effective-
ness of the ABS and ESP ®
in winter opera-
tion.
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 216).
Always observe the speed rating of the win-
ter 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 electric drive
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 fol-
lowing tire size:

WARNING
When jacking up the vehicle, only use a
suitable jack. Observe the manufacturer’s
safety instructions.
The jack must be designed for jacking up
this vehicle at the jack take-up brackets
built into both sides of the vehicle.
The jack is intended only for lifting the
vehicle briefly for wheel changes. It is not suited for performing maintenance work
under the vehicle. To help avoid personal
injury, use the jack only to lift the vehicle during a wheel change.
Never get beneath the vehicle while it is
supported by the jack. Keep hands and feet
away from the area under the lifted vehicle.
Always lower the vehicle onto sufficient
capacity jackstands before working under
the vehicle.
Always firmly engage the parking brake and block the wheels with wheel chocks or othersizeable objects before raising the vehi-
cle with the jack. Do not release the parking
brake while the vehicle is raised.
Make sure the ground on which the vehicle
is standing and where you place the jack is solid, level and not slippery. If necessary,
use a large underlay. On slippery surfaces, such as tiled floors, you should use a non-
slip underlay, for example a rubber mat.
Do not use wooden blocks or similar objects
to support the jack. Otherwise the jack may
not be able to achieve its load-bearing
capacity if it is not at its full height.
The jack must always be vertical when in
use. Always try to use the jack on level sur- face. If you do not position the jack cor-
rectly, the vehicle can fall off the jack and
seriously or fatally injure you or others.
Never switch on the drive system when the
vehicle is raised.
Also observe the notes on the jack.
X Make sure to have a suitable jack 10
, wheel
wrench 10
and wheel chock 10
.
Contact an authorized electric drive
smart center for information on which
jack and wheel wrench are required.
X Prepare the vehicle as described
(Y page 195).
X Make sure the surface is level.
Prevent the vehicle from rolling away by
blocking wheels with wheel chocks or other sizeable objects:
X Place one wheel chock or other sizeable
object in front of and another wheel
chock or other sizeable object behind
the wheel that is diagonally opposite to
the wheel being changed.
X On wheel to be changed, loosen but do not
yet remove the wheel bolts (approx-
imately one full turn with wheel wrench).
! Only position the jack on the designa-
ted take-up brackets.
You must not position the jack under the
high-voltage battery. Otherwise, the
high-voltage battery could be damaged.
