IN AN EMERGENCY

JUMP STARTING
STARTING THE ENGINE
If the iconstays on constantly on the
instrument panel, contact the Alfa
Romeo Dealership immediately.
JUMP STARTING
If the battery is flat, start the engine
using an auxiliary battery with the same
capacity or a little higher than the flat
one.
38) 39)125)
Proceed as follows to start the vehicle:
connect the positive terminal (+)
fig. 104 of the auxiliary battery only to
the point indicated on the car battery
(writing "OK") and nowhere else;
with a second lead, connect the
negative terminal(−)oftheauxiliary
battery to an earthing point
on the
engine or the gearbox/transmission of
the car to be started;
start the engine; when the engine has
been started, remove the leads reversing
the order above.
If after a few attempts the engine does
not start, contact the Alfa Romeo
Dealership.
JUMP STARTING
(For versions with Start&Stop system)
When jump starting, never connect the
negative lead (–) of the auxiliary battery
to the negative pole 1 fig. 105 of the car
battery, but rather to an engine/gearbox
earth point.
126)
BUMP STARTING
Never, under any circumstances, jump
start the engine by pushing, towing or
coasting downhill.
IMPORTANT
38)Never connect the negative terminals of
the two batteries directly! If the auxiliary
battery is installed on another car, prevent
accidental contact between metallic parts of
the two cars.
39)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.
WARNING
125)This starting procedure must be
performed by expert personnel because
incorrect actions could cause electrical
discharge of considerable intensity.
Furthermore, battery fluid is poisonous and
corrosive: avoid contact with skin and eyes.

components.
136)Some commercial additives for
windscreen washer fluid are flammable. The
engine compartment contains hot
components which may start a fire.
137)Brake fluid is poisonous and highly
corrosive. In the event of accidental contact,
immediately wash the affected parts with
water and mild soap. Then rinse thoroughly.
Call a doctor immediately if swallowed.
138)The symbol
, on the brake fluid
container indicates if a brake fluid is
synthetic or mineral-based. Use of mineral
type fluids will damage the special rubber
seals of the braking system beyond repair.

rating for approximately 24 hours.
Charging for a longer time may damage
the battery.
IMPORTANT The cables of the electrical
system must be correctly reconnected to
the battery, i.e. the positive cable (+) to
the positive terminal and the negative
cable (–) to the negative terminal. The
battery terminals are marked with the
positive (+) and negative (–) symbols, and
are shown on the battery cover. The
battery terminals must also be
corrosion-free and firmly secured to the
terminals. If a "quick-type" battery
charger is used with the battery fitted on
the vehicle, before connecting it
disconnect both cables of the battery
itself. Do not use a "quick-type" battery
charger to provide the starting voltage.The cables of the electrical system must
be correctly reconnected to the battery,
i.e. the positive cable (+) to the positive
terminal and the negative cable (–) to the
negative terminal. The battery terminals
are marked with the positive (+) and
negative (–) symbols, and are shown on
the battery cover. The battery terminals
must also be corrosion-free and firmly
secured to the terminals.

. To carry out
this procedure, simply turn the steering
wheel all the way from one end to the
other or drive in a straight line for about a
hundred metres.
IMPORTANT If the charge level remains
under 50% for a long time, the battery is
damaged by sulphation, reducing its
capacity and efficiency at start-up.
The battery will also be more at risk of
freezing (this can happen as early as
-10°C). Refer to the "Vehicle inactivity"
paragraph in "Starting and driving"
chapter if the vehicle is left parked for a
long time.If, after purchasing the car, you wish to
install electrical accessories which
require permanent electrical supply (e.g.

influence the electrical supply
requirements, contact an Alfa Romeo
Dealership, whose qualified staff will
evaluate the overall electrical
consumption.
WARNING
140)Battery fluid is poisonous and
corrosive. Avoid contact with the skin and
eyes. Keep open flames away from the
battery and do not use objects that might
create sparks: risk of explosion and fire.
141)Using the battery with insufficient
fluid irreparably damages the battery and
may cause an explosion.
142)If the vehicle must remain unused for a
long time at a very low temperature, remove
the battery and take it to a warm place, to
avoid freezing.
143)When performing any operation on the
battery or near it, always protect your eyes
with special goggles.
IMPORTANT

to your car. After purchasing your vehicle, if
you wish to install any accessories (e.g.
anti-theft, radio phone, etc.), go to an Alfa
Romeo Dealership, which will suggest the
most suitable devices and advise you
whether a higher capacity battery needs to
be installed.
IMPORTANT
5)Batteries contain substances which are
very dangerous for the environment. For
battery replacement, contact an Alfa Romeo
Dealership.
