IMPORTANT Do not directly connect
the negative terminals of the two
batteries: any sparks may ignite the
explosive gas which could come
out of the battery. If the auxiliary
battery is installed on another
vehicle, avoid any metal parts on the
latter and the vehicle with the flat
battery from accidentally coming
into contact.

BUMP STARTING
Never bump start the engine by
pushing, towing or coasting
downhill. This could cause fuel to
flow into the catalytic converter and
damage it beyond repair.

IMPORTANT Remember that the
brake booster and the electric
power steering system are
not active until the engine is started,
so you will need to apply much
more force to the brake pedal or
steering wheel.

IMPORTANT
29) Never use a fast battery-charger
for emergency starting of the
engine as this could damage the
electronic systems of your vehicle,
particularly the ignition and fuel
supply control units.
WARNING
121) 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 away from the
battery. No smoking. Do not cause
sparks.
