194 IN THE EVENT
OF A FLAT BATTERY
STARTING WITH AN
AUXILIARY BATTERY
If the battery is flat, it is possible to start the
engine using an auxiliary battery (B-fig.
96) with the same electrical characteristics
as the original battery (A-fig. 96) (see
chapter “Technical specifications”).
The battery is housed on the left-hand
side of the boot, protected by a cover.
If the battery is low, the servocontrol
operating when the luggage compart-
ment opens from inside or by the key
does not work. However, it is always pos-
sible to open the luggage compartmentto reach the battery. Just rotate the key
wider simultaneously pressing on the bon-
net edge by the hand.
IMPORTANTApply a moderate pres-
sure only on the bonnet edge, immediate-
ly above the lock.
On versions without navigation system and
without CD player, access to the battery is
gained by slackening the knob (A-fig. 94)
and removing the battery cover.
On versions with navigation system and
/or CD player, access to the battery is
gained by slackening the knobs (A-fig.
95) and removing the cover (B).
Starting with an auxiliary battery does
not damages the Alfa Romeo CODE sys-
tem and must be carried out as follows:– Switch off all the not strictly neces-
sary electric devices.
– Connect a jump lead to the positive
terminals (1-fig. 96) of the two batter-
ies (+ sign next to the terminal).
– Connect another jump lead to the
negative terminals (2) of both batteries
(– sign next to the terminal).
– Start the engine.
– When the engine has started, remove
the cables reversing the sequence de-
scribed for connecting them.
– If after a few attempts, the engine
fails to start, do not insist pointlessly and
contact the nearest Authorized Alfa
Romeo Services.

196 IF THE VEHICLE
IS TO BE TOWED
Towing the vehicle (fig. 97)
The rings for towing the vehicle are
housed in the right and left lower part of
the underbody.
Towing another vehicle
(fig. 98-99)
The tow ring supplied with the vehicle is
housed in the tool container under the
boot mat.To install the tow ring, proceed as fol-
lows:
– Take the tow ring from the tool con-
tainer.
– Remove the cover (A-fig. 98) s-
nap-fitted on the rear bumper as follows:
Take the screwdriver from the tool con-
tainer in the boot, under the trim.Using the flat bladed side protected with
a soft cloth, insert the screwdriver on the
upper part of the cap and press gently to
prise the catch from its housing.
– Firmly screw the ring (B-fig. 99) in
its housing.
Make sure that the tow
ring is firmly tightened (it
must be turned about 8 times in its
threaded housing); carefully clean
the threaded housing before tight-
ening the ring.

206 ANNUAL INSPECTION
PLAN
An annual inspection plan has
been established for cars that cov-
er less than 20,000 km a year
(e.g. 10,000 km). It consists of
the following:
– Checking the condition/wear of tyres,
and adjusting pressure (including the com-
pact spare wheel, where applicable).
– Checking the lighting system (head-
lights, turn indicators, hazard warning
lights, boot light, passenger compart-
ment, warning lights of instrument panel,
etc.).
– Checking the working order of the
windscreen wiper-washer and adjusting
the nozzles.
– Checking the positioning/wear of the
windscreen wipers.
– Checking the condition and wear of
the front brake pad.– Sight inspect the conditions of: en-
gine, gearbox, transmission, pipes and
hoses (exhaust - fuel - brakes), rubber
parts (boots, sleeves, bushes, etc.).
– Check for bonnet and boot lock clean-
ness, lever cleanness and lubrication.
– Check battery charge and fluid level
(electrolyte).
– Visually checking the condition of the
belts and various controls.
– Checking and topping up, if neces-
sary, the level of liquids (coolant, brake
fluid, windscreen washer fluid, battery
etc.).
– Change engine oil and oil filter, if re-
quired.
– Check and replace pollen filter, if re-
quired.
– Check and replace air cleaner, if re-
quired.
ADDITIONAL OPERATIONS
Every 1000 kmor before long jour-
neys check and if necessary top up:
– the engine coolant fluid level
– brake fluid/hydraulic clutch control
fluid level
– power steering fluid level
– windscreen washer and headlamp
washer fluid level
– tyre pressure and conditions.
– check light system operation (head-
lights, direction indicators, hazard lights,
etc.).
– check windscreen wiper/washer op-
eration and windscreen/rear window
blade position/wear.
Every 3000 kmcheck the level of
the engine oil and top up if necessary.
Every 5000 km(only for fuel oil en-
gines): drain the condensation water
from the filter. You are recommended to
use products of the FL Selenia, de-
signed and developed expressly for Alfa
Romeo cars (see the table “Fluids and lu-
bricants” in the Technical specifications”
chapter).

219
DUST/POLLEN FILTER
The filter mechanically/electrostatically
filters the air provided that the windows
are shut.
The dust/pollen filter should be checked
over once a year by Alfa Romeo Autho-
rized Service station preferably at the be-
ginning of the summer.
If the vehicle is habitually driven in
cities, motorways or on dusty roads the
system should be checked over more of-
ten than specified in the Programmed
Maintenance Schedule.
IMPORTANT If the filter is not re-
placed the efficiency of the climate con-
trol system may be seriously compro-
mised.

WATER
BATTERY
The battery is housed on the left-hand
side of the boot, protected by a cover.
On versions without navigation system
and without CD player, access to the bat-
tery is gained by slackening the knob
(A-fig. 14) and removing the battery
cover.
On versions with navigation system and
/or CD player, access to the battery is
gained by slackening the knobs (A-fig.
15) and removing the cover (B). Water in the supply cir-
cuit can seriously dam-
age the whole injection
system and cause malfunctions
to engine operation. Should the
warning lamp c, contact as
soon as possible the Alfa Romeo
Authorised Service for drainage
operations.

– Before doing any work on the electric
system, disconnect the battery negative
terminal.
If after purchasing the car, you wish to
install electrical accessories which need a
permanent electrical supply (alarm,
hands-free phone, radio-navigator with
satellite anti-theft function, etc.) contact
Authorised Alfa Romeo Services whose
qualified personnel, in addition to sug-
gesting the most suitable devices from
Lineaccessori will be able to evaluate the
total electrical absorption, checking
whether the car’s electric system is able
to support the load required or whether a
battery with higher capacity is necessary.
In fact, these devices continue to absorb
current with the ignition key off (car
parked, engine off) and may gradually
drain the battery. IMPORTANT A battery kept at below
50% of its capacity is damaged by sul-
phation, the capacity is reduced and start-
ing is difficult, there is also more possibili-
ty of freezing (this can occur at –10°C).
In the event of a prolonged stop, refer to
“Vehicle inactivity”.
USEFUL HINTS TO EXTEND
THE LIFE OF YOUR BATTERY
To avoid quickly draining the battery
and to preserve its operating conditions
over the course of time, carefully follow
the instructions below.
– The terminals must always be tight-
ened.
– As far as possible avoid keeping ser-
vices on for a long time with the engine
stopped (radio, hazard warning lights,
parking lights, etc.).
– When leaving the vehicle parked in a
garage, make sure that the doors, bon-
net, boot and interior lids are properly
shut to prevent lights from staying on.
The fluid contained in the
battery is poisonous and
corrosive. Avoid contact with the
skin or eyes. The battery should be
charged in a ventilated place away
from naked flames or possible
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.
