DISCONNECTING THE
UNLOADED BATTERY
Should the discharged battery be
disconnected (to have it charged
again or to replace it) perform the fol-
lowing operations in the given order:
1) To open the boot from the out-
side, fully turn the key anticlockwise
in the lock (fig. 81), and at the same
time slightly press the lower edge of
the number plate holder to reduce op-
eration effort.
2) Remove the cover and disconnect
the battery terminals.
3) Fully charge the battery again or
replace it.4) Connect battery terminals and re-
assemble cover.
5) Depress push button A(fig. 81)
to restore normal lock operation.
6) Close boot normally without
slamming it down: lock electric servo
control will fully lock it.
7) Perform the initialisation proce-
dure of the door lock, air conditioner
and ESP system control units, here-
after described.INITIALISING THE CONTROL
UNITS OF THE DOOR LOCKS,
AIR CONDITIONER AND ESP
SYSTEM
Whenever the battery is connected
electrically or protection fuses are re-
placed, to restore correct door locking,
air conditioning and ESP system, per-
form the following operations (after
connection is performed or after re-
placing one of the fuses):
1) Enter key into the lock of one of
the front doors and perform a door
centralised opening/closing cycle.
2) Start the engine and turn on the
compressor of the conditioner, setting
a lower temperature value than that
of the environment and check
whether the led on the disconnection
push button of the conditioner com-
pressoròis lit.
3) Start running the car and drive it
for a few meters in a straight line (ac-
celerating), until the ESP warning
light is off
á. It is not possible to close
the boot when battery is
discharged or discon-
nected for the purpose of being re-
placed/ charged again: do not try
to close the boot by slamming it
down. The boot remains anyhow
hooked on and it must be re-
opened by turning the key in the
lock.

ADDITIONAL
CHECKS
Every 1,000 kmor before long
trips, check and top up as necessary:
– engine coolant level
– brake/hydraulic clutch fluid
level
– power steering fluid level
– windscreen/rear window and
headlight washer fluid level
– tyre pressure and conditions.
Every 3,000 kmcheck the engine
oil level and top up as necessary.
You are recommended to use FL
Seleniaproducts that are designed
and produced specifically for LAN-
CIA cars (see “Capacities” in
“Technical Specifications”).
ANNUAL
INSPECTION
SCHEDULE
The following annual inspection
schedule is recommended for
cars travelling less than 20,000
km a year (e.g. approximately
10,000 km). The schedule
includes the following opera-
tions:
1) Check tyre condition and wear
and adjust pressure (including spare
wheel)
2) Check wear on windscreen/rear
window blades
3) Check rear disc brake pad con-
ditions and wear
4) Inspect conditions of: under-
body protection and outside body-
work, piping (exhaust - fuel lines -
brake lines), rubber parts (boots -
sleeves - bushings, etc.), brake and
fuel line hoses5) check for bonnet and boot lock
cleanness, lever cleanness and lubri-
cation
6) Check primary and secondary
battery charge status
7) Check conditions of various con-
trol belts
8) Check and top up fluid levels
(engine coolant, brakes, windscreen
washer, battery, etc.)
9) Change engine oil
10) Replace engine oil filter
11) Replace dust/pollen filter.

USEFUL ADVICE FOR
LENGTHENING THE LIFE OF
YOUR BATTERY
To prevent rapidly draining the
battery and ensure that it continues
to work correctly, the following
should be noted:
– Terminals must always be firmly
tightened.
– Do not keep accessories (e.g.
sound system, hazard lights, parking
lights, etc.).
– When you park the car, ensure
the doors, boot and bonnet are
closed properly. The ceiling lights
must be off.
– Before working on the electrical
system, disconnect the negative
cable from the battery.– If after buying the car, you want
to install electric accessories which
require permanent electric supply,
visit a Lancia Dealership, whose
qualified personnel, in addition to
suggesting the most suitable devices
belonging to the Lineaccessori
Lancia, will evaluate the overall
electric absorption, checking
whether the car’s electric system is
capable of withstanding the load
required, or whether it should be
integrated with a more powerful
battery. These devices in fact take
electricity also when the ignition key
is removed (car parked, engine off),
and can gradually drain the battery.
The overall intake of these devices
(standard and after-market) must
be less than 0.6 mA x Ah (of the bat-
tery), as shown in the following
table.Battery Maximum
idle intake
70 Ah 42 mA
80 Ah 48 mA
100 Ah 60 mA
It is also important to remember
that high intake devices (such as
bottle warmers, vacuum cleaners,
cellular phones, frigo bar, etc.) will
speed up battery discharging when
powered with engine off or running
idle.
– Please note that when installing
additional systems in the car, incor-
rect wiring can be dangerous espe-
cially when concerning safety sys-
tems.
