If it is often necessary to perform a
jump starting, have the vehicle battery
and the recharging system checked
by a Fiat Dealership.
IMPORTANT Any accessories (e.g.
mobile phones, etc.) connected to the
vehicle power 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
156) This procedure must be performed by
qualified personnel as incorrect actions
may cause high-intensity electrical
discharge. Furthermore, battery fluid is
poisonous and corrosive: avoid contact
with skin and eyes. Keep naked flames and
lighted cigarettes away from the battery
and do not cause sparks.
157) Remove any metal objects (e.g. rings,
watches, bracelets), that might cause an
accidental electrical contact and cause
serious injury.
WARNING
53) Do not connect the cable to the
negative terminal (–) of the flat battery. The
following spark could lead to battery
explosion and cause serious harm. Only
use the specific earth point; do not use any
other exposed metallic part.
54) Never use a fast battery-charger to
start the engine as this could damage the
electronic systems of your vehicle,
particularly the ignition and engine fuel
supply control units.
