IN THE EVENT OF A FLAT BATTERYFirst of all, you are advised to refer to the
“Car maintenance” chapter for precautions
to be adopted in order to prevent the bat-
tery from getting flat and to ensure its long
durability.CHARGING THE BATTERYWARNINGThe description of the bat-
tery charging procedure is described only for
informative purposes. This operation should
be carried out by Alfa Romeo Authorized Ser-
vices.
Charging should be slow at a low amp rat-
ing for about 24 hours. Charging for a longer
time may damage the battery.Charge the battery as follows:
– Disconnect the terminal from the bat-
tery negative (–) pole.
– Connect the charger cables to the bat-
tery, respecting polarity.
– Turn on the charger.
– After charging turn off the charger be-
fore disconnecting it from the battery.
– Reconnect the terminal to the battery
negative (–) pole.
STARTING WITH AN AUXILIARY
BATTERYSee “Starting with an auxiliary battery” in
this chapter.
The fluid contained in the
battery is poisonous and
corrosive. Avoid contact with the
skin or eyes. The battery should be
charged in a well ventilated place
and kept away from naked flames
or sources of sparks: danger of ex-
plosion and fire.
WARNING
Never attempt to charge a
frozen battery before
thawing it, the danger of explosion
exists. If it has frozen, always
check that the inside elements are
not broken (risk of short circuit)
and that the body is not cracked,
with the risk of acid coming out
which is poisonous and corrosive.

TOWING THE 2.0 JTS
SELESPEED VERSIONWARNINGFor version with Selespeed
gearbox, make sure that it is in neutral (N)
(checking that the car moves when pushed)
and proceed as for towing a normal car with
mechanical gearbox following the instruc-
tions given on the previous page.
Should it be impossible to set to neutral,
do not tow the vehicle; contact Alfa Romeo
Authorised Services.
TOWING THE VERSION WITH
AUTOMATIC GEARBOX
(2.5 V6 24V Q-SYSTEM)WARNINGFor towing the vehicle com-
ply with current local regulations. Also fol-
low the instructions given on the previous
page.
If the car needs to be towed, observe the
following recommendations:
– if possible, put the car on a rescue ve-
hicle;
– if this is not possible, tow the car rais-
ing the driving wheels (front) from the
ground;
– if this, too, is not possible, the car may
only be towed for 50 Km at a speed of
50 km/h.
The gearshift lever should be at position N
for towing.The failure to follow the
above instructions may
cause serious damage to
the automatic gearbox.
Cars with automatic gear-
box may be towed only for
short distances and at a
low speed: if longer towing is nec-
essary, the driving wheels must be
raised to prevent the gearbox from
being pulled into rotation during
towing.
Do not start the engine
when towing the vehicle.
WARNING
Do not start the engine
when the vehicle is being
towed.

CAR MAINTENANCE
253
Car maintenance should be
entrusted to Alfa Romeo
Authorized Services. For
routine and minor maintenance op-
erations you wish to carry out
yourself, always make sure you
have the proper equipment, genuine
Alfa Romeo spare parts and the
necessary fluids; do not however
carry out these operations if you
have no experience.
WARNING
Pollen filter
If the car is used frequently in dusty or
heavily polluted environments it is advisable
to replace the filtering element more fre-
quently; in particular it should be replaced if
a reduction of the amount of air admitted to
the passenger compartment is noted. WARNING
Battery
You are recommended to have the battery
charge conditions checked, preferably at the
onset of winter, to avoid the possibility of
freezing the electrolyte.
This check should be carried out more fre-
quently if the car is used prevailingly for
short journeys, or if it is fitted with services
that absorb high amounts of current per-
manently with the ignition key off, especially
if installed in the after market.
In the case of use of the car in hot climates
or particularly harsh conditions, it is wise
to check the level of the battery fluid (elec-
trolyte) at more frequent intervals than stat-
ed in the Scheduled Maintenance Pro-
gramme.

The engine oil level should be checked
when the car is standing on a level surface
a few minutes (about 5) after the engine
has been switched off.
Remove the dipstick (A), clean it, put it
back completely, remove it once again and
check that the level is between the MIN
and MAXmarks on the dipstick.
The interval between the MINand MAX
marks corresponds to approximately 1 liter
of oil.If the oil level is near or even below the
MIN, mark, add oil trough the filler neck
(B), until reaching the MAXmark. Never add oil with char-
acteristics (classification,
viscosity) which are differ-
ent from those of the oil already in
the circuit.fig. 7 - T.SPARK versions fig. 8 - 2.0 JTS version

When the engine is hot,
take care when working
inside the engine compartment to
avoid burns. Remember that when
the engine is hot, the fan may cut
in: danger of injury.
WARNING
Scarves, ties and other
loose clothing might be
pulled by moving parts.

WARNINGIf a routine check reveals
that the oil level is above the MAXmark,
contact Alfa Romeo Authorized Services to
have the correct level restored.
WARNINGAfter adding or changing the
oil, run the engine for a few seconds and
wait a few minutes after stopping it.Used engine oil and filter
contain pollutants. Contact
Alfa Romeo Authorized
Services to have the oil and filter
changed as these are equipped to
dispose of the waste oil and filters
respecting the environment and
laws.fig. 10 - JTD version

fig. 12 - JTD 20V Multijet version Engine oil consumption
Max. engine oil consumption is usually
400 grams every 1000 km.
During the initial period of use the engine
settles, therefore the engine oil consump-
tion can only be considered stabilised after
the first 5000 ÷ 6000 km.
WARNINGEngine oil consumption de-
pends on the way of driving and the condi-
tions of use of the car.
