Fiat 500 Owner's Handbook Manual page 104

Proceed as follows:
❒ Connect positive terminals (+ sign near
the terminal) of the two batteries with
a jump lead;
❒ With a second lead, connect the nega-
tive terminal (–) of the auxiliary battery
to an earthing point E on the engine or
the gearbox of the car to be started;
❒ Start the engine;
❒ When the engine has been started, re-
move the leads reversing the order
above.
If after a few attempts the engine does not
start, do not insist any further but contact
the nearest Fiat Dealership.
IMPORTANT Never connect the negative
terminals of the two batteries directly:
sparks could ignite explosive gas released
from the battery. If the auxiliary battery is
installed on another car, prevent acciden-
tal contact between metallic parts of the
two cars.
BUMP STARTING
Never jump start the engine by pushing,
towing or driving downhill.
This could cause a flow of fuel into the cat-
alytic converter and damage it beyond re-
pair.
IMPORTANT Remember that the brake
booster and the power steering system (if
present) are not operating until the engine
is started, a greater effort will therefore
be required to press the brake pedal or
turn the steering wheel.
