IMPORTANT Any accessories (e.g.
mobile phones, etc.) connected to the
vehicle current sockets, draw current
even if they are not used. These
devices, if left connected too much time
with engine off, may cause the battery
to drain with following reduction of
its life and/or failure to start the engine.
WARNING
157) Do not get too close to the radiator
cooling fan: the electric fan may start;
danger of injury. Pay attention to scarves,
ties and other loose clothing which might
be pulled by moving parts.
158) Remove any metal objects (e.g. rings,
watches, bracelets), that might cause an
accidental electrical contact and cause
serious injury.
159) Batteries contain acid which may burn
skin and eyes. Batteries produce
hydrogen, which is easily flammable and
explosive. Thus keep away flames or
devices which may cause sparks.
