JUMP-STARTING
If the battery is flat, a jump starting
can be performed using the battery and
the cables of another car, or using an
auxiliary battery. In all cases, the battery
used must have a capacity equal to or a
little higher than the flat one.
Jump-starting can be dangerous if not
done correctly. Follow the procedures in
this section carefully.
