of whether the high-voltage battery is
charged
or not. Jump starting will not help
to start the drive system if the high-
voltage battery is drained. The high-
voltage battery must then be charged.
The drive system can be started with jumper
cables and the fully charged battery of
another vehicle or an equivalent starter
pack.
Observe the following:
R
Do not start the drive system if the
battery is frozen. Let the battery thaw out
first.
R
Only jump start from batteries with the
same voltage rating (12 V). Jump starting
with a more powerful battery could
damage the vehicle’s electrical system.
Such damage will not be covered by the
smart Limited Warranty.
R
Only use jumper cables with sufficient
cross-section and insulated terminal
clamps.
R
Should the battery be drained
completely, let the donating power
source charge the vehicle for several
minutes before reattempting the
starting process.
G
