battery capacity SMART FORTWO COUPE ELECTRIC DRIVE 2013 Owners Manual

Use only charging cables which have been
approved and recommended for the vehicle.
Do not use:
R extension chords
R cable reels
R multiple sockets
R travel adapters
i When possible, only charge the
high‑voltage battery when the charge
level is below 80 %.
It is recommended to charge the
high‑voltage battery prior to reaching
less than 20% state of charge.
Discharged high‑voltage battery When the high‑voltage battery is
completely discharged, the drive system is
switched off. This protects the battery
from exhaustive discharge.
i By switching the ignition off and on
again, the drive system can be briefly
reactivate donce. This allows you to park
the vehicle safely.
Do not allow your vehicle to remain
stationary for more than 14 days with a
discharged, or nearly discharged,
high‑voltage battery. You can check the
charge level with the charge level gauge
(Y page 79).
High or low outside temperatures The efficiency of the high‑voltage battery
is temperature-dependent and decreases
at high or low temperatures .Additionally,
the electrolytes used can gel at very low
temperatures.
You can check the maximum capacity
available using the indicator in the
multifunction display (Y page 83).Energy consumption and range The available energy of the high‑voltage
battery is reduced by:
R
low outside temperatures
R switching on electrical consumers
At low temperatures and after being parked
for an extended period without charging,
the physical properties of the
high‑voltage battery:
R can cause a significant reductio ninthe
performance of the battery
R can lead to longer charging times
In extreme cases, you will not be able to
start the vehicle. For this reason, always
connect the charging cable or make sure the
battery is completely charged when
parking the vehicle in low outside
temperatures or for an extended period of
time.
Due to its physical properties, the
capacity of a high‑voltage battery
decreases over its lifespan.
Thus, the following are reduced:
R the maximum attainable range of the
vehicle
R the maximum performance output
(acceleration) of the vehicle
You can actively contribute to the
reduction of the vehicle's energy
consumption by:
R driving conservatively
R maintaining the vehicle regularly
R decreasing the use of electrical
consumers
Notes on battery care Avoid storing and transporting the vehicle
at high temperatures for extended periods
of time (e. g. container transport).
When out of use for longer periods of time,
connect the vehicle to a voltage supply.
If the vehicle is not connected to
avoltage
supply, it must remain within a High-voltage battery

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
“Manufacturer’s identification mark”,
“Tire size”, “Tire type code” and “Date of
manufacture”.
Tire load rating
Numerical code associated with the
maximum 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
manufacturers also must indicate the ply
materials in the tire and sidewall, which
include steel, nylon, polyester, and others.

139>> Operation. Z

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
traction, 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
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
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 212).
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 0001on 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 210).
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 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
following tire size: 140

WARNING
Windshield washer concentrate is highly
flammable. Fire, naked flames and smoking
are prohibited when windshield washer
concentrate is being handled. Coolants
The battery and drive system coolant is a
mixture of water and anticorrosion/
antifreeze, which provides:
R Corrosion protection
R Freeze protection
R Boiling protection (by increasing the
boiling point)
The cooling system was filled at the factory
with a coolant providing freeze protection
to approximatel y-35¦ (-37¥) and
corrosion protection.
! Add premixed coolant solution only.
Adding water and MB 325.0
Anticorrosion/Antifreeze separately
from each other, could cause drive system
damage not covered by the smart Limited
Warranty.
If the antifreeze mixture is effective to
-35¦ (-37¥), the boiling point of the
coolant in the pressurized cooling system
is reached at approximately 266¦
(130¥ ).
The coolant solution must be used year
round, even in countries which have high
temperatures to provide the necessary
corrosion protection and increase
boil‑over protection. Refer to
Maintenance/ Service Booklet for
replacement interval.
Coolant system design and coolant used
determine the replacement interval. The
replacement interval published in the
Maintenance booklet is only applicable if
MB 325.0 Anticorrosion/Antifreeze
solution or other smart approved products
of equal specification are used to renew the coolant concentration or bring it back
up to the proper level.
For information on other smart approved
products of equal specification, contact an
authorized electric drive smart center.
To provide important corrosion
protection, the solution must be at least
50% anticorrosion/antifreeze (equivalent
to freeze protection to approximately
-35¦
[-37¥]).
If you use a solution that is more than 55%
anticorrosion/antifreeze (freeze
protection to approximately -49 ¦
[(-45¥]), the drive system and battery
temperature will increas edue to the lower
heat transfer capability of the solution.
Therefore, do not use more than this amount
of anticorrosion/antifreeze.
If the coolant level is low, water and
MB 325.0 Anticorrosion/Antifreeze should
be used to bring it up to the proper level
(have cooling system checked for signs of
leakage). Please make sure the mixture is
in accordance with label instructions.
Always use anticorrosion/antifreeze that
has been approved by smart. For
information contact an authorized electric
drive smart center.
The water in the cooling system must meet
minimum requirements, which are usually
satisfied by normal drinking water.
If you are not sure about the water quality,
consult an authorized electric drive smart
center.
