Battery Care - SMART fortwo coupe Owner's Manual

Charging the high-voltage battery
78
therefore always ensure that the battery is
fully charged or that the charging cable is
connected when parking the vehicle for an
extended period of time at low outside tem-
peratures.
Due to its physical properties, the capa-
city of the high-voltage battery will
diminish over its lifetime.
This will also reduce:
the maximum vehicle range that can be
R
achieved
the maximum output (acceleration) of the
R
vehicle
You can actively contribute to reducing the
energy consumption of the vehicle, among
other things, by:
driving conservatively
R
bringing the vehicle in for regular
R
maintenance
reducing the use of electrical consumers

Notes on battery care
Avoid storing and transporting the vehicle
at high temperatures and over an extended
period of time (e.g. moving it in a trans-
port container).
Connect the vehicle to a power supply when
parking it for an extended period of time.
If the vehicle is not connected to a power
supply, the temperature must remain
between Ò20 ¥ and 40 ¥.
Temperatures below Ò25 ¥ for more than
seven days can cause irreversible damage
to the vehicle due to frost damage.
Terms of use
Observe the following notes:

the implied and explicit warranty docu-
ments as well as in the Service Booklet

Voltage surge protector
! Voltage surges in the mains supply can
damage the vehicle. The vehicle is
therefore equipped with a device which
protects it from voltage surges in the
mains supply. This device may be trig-
gered during severe thunderstorms, for
example, and may cause the building's
fuse unit to trip out. The purpose of this
function is to protect the vehicle. When
the building's fuse unit is switched on
again, the charging process resumes
automatically.
After the device has triggered, switch the
building's fuse unit on again. Otherwise,
the charging process will not resume. The
high-voltage battery will not be charged
and as a result, it may not be possible to
drive the vehicle.
If the same fuse unit also protects other
items of equipment, they will also be
switched off if the unit has tripped. Make
sure that these devices are functioning
again after switching the fuse unit back on.
Handling the charging cable and the con-
trol panel on the charging cable
Do not leave the control panel on the charg-
Y
ing cable ( page 80) hanging loose from
a mains socket. Otherwise, this could lead
to a bad contact with the mains socket and
to malfunctions when charging the vehicle.
