CORRECT USE
OF THE CAR
Climate control
The air conditioner is an additional load
which greatly affects the engine leading
to higher consumption. When the tem-
perature outside the car permits it, use
the air vents where possible.
Spoilers
The use of aerodynamic optional extras
which are not certified for the specific
use on the vehicle, may reduce the aero-
dynamic penetration of the vehicle and
increase consumption. Unnecessary loads
Do not travel with too much luggage
stowed in the boot. The weight of the
car (especially when driving in town)
and its trim greatly affects consumption
and stability.
Roof rack/ski rack
Remove the roof rack or the ski rack
from the roof as soon as they are no
longer used. These accessories lower air
penetration and adversely affect con-
sumption levels. When needing to car-
ry particularly voluminous objects, prefer-
ably use a trailer.
Electric devices
Use electric devices only for the amount
of time needed. Rear heated window,
additional headlights, windscreen wipers
and heater fan need a considerable
amount of energy, therefore increasing
the requirement of current increases fu-
el consumption (up to +25% in the ur-
ban cycle).CONTAINING
RUNNING COSTS
Here are some suggestions which may
help you to keep the running costs of
your car down and lower the amount of
toxic emissions released into the at-
mosphere.
GENERAL CONSIDERATIONS
Car maintenance
Have checks and adjustments carried out
in accordance with the “Service sched-
ule”.
Tyres
Check the pressure of the tyres routine-
ly at an interval of no more than 4
weeks: if the pressure is too low, con-
sumption levels increase as resistance
to rolling is higher.

Gear selection
As soon as the conditions of the traffic
and road allow, use a higher gear. Us-
ing a low gear to obtain brilliant perfor-
mance increases consumption. In the
same way improper use of a high gear
increases consumption, emissions an en-
gine wear.
Top speed
Fuel consumption considerably increas-
es with speed. Avoid superfluous brak-
ing and accelerating, which cost in terms
of both fuel and emissions.
Acceleration
Accelerating violently increasing the revs
will greatly affect consumption and emis-
sions: acceleration should be gradual and
should not exceed the maximum torque.CONDITIONS OF USE
Cold starting
Short journeys and frequent cold starts
do not allow the engine to reach opti-
mum operating temperature. This results
in a significant increase in consumption
levels (from +15 to +30% on the urban
cycle) and emission of harmful sub-
stances.
Traffic and road conditions
Rather high consumption levels are tied
to situations with heavy traffic, for ex-
ample in queues with frequent use of
the lower gears or in cities with many
traffic lights. Also winding mountain
roads and rough road surfaces adverse-
ly affect consumption.
Traffic hold-ups
During prolonged hold-ups (e.g.: level
crossings) the engine should be
switched off.
DRIVING STYLE
Starting
Do not warm the engine with the car
at a standstill or at idle or high speed:
under these conditions the engine
warms up much more slowly, increasing
electrical consumption and emissions. It
is therefore advisable to move off im-
mediately, slowly, avoiding high speeds.
This way the engine will warm faster.
Unnecessary actions
Avoid accelerating when waiting at traf-
fic lights or before switching off the en-
gine. This and also double declutching
is absolutely pointless on modern cars
and also increase consumption and pol-
lution.

CORRECT USE
OF THE CAR
Engage a low gear when driving down-
hill, rather than constantly using the
brake.
The weight the trailer exerts on the car
tow hook reduces by the same amount
the actual car loading capacity. To make
sure the maximum towable weight is
not exceeded (given in the log book)
account should be taken of the fully
laden trailer, including accessories and
personal belongings.
Do not exceed the speed limits of the
country you are driving in. In any case
do not exceed 100 km/h.TOWING TRAILERS
IMPORTANT NOTES
For towing caravans or trailers the car
must be fitted with a certified tow hook
and an adequate electric system. In-
stallation should be carried out by spe-
cialised personnel who release a special
document for circulation on the road.
Install any specific and/or additional
rear-view mirrors as specified by law.
Remember that when towing a trailer,
steep hills are harder to climb, the brak-
ing spaces increase and overtaking takes
longer depending on the overall weight.
The ABS system with
which the car may be
fitted does not control the
trailer braking system. Drive
with extreme care on slippery
roadbeds.
WARNING
Under no circumstances
should the car brake
system be altered to control
the trailer brake. The trailer
braking system must be fully
independent of the car hy-
draulic system.

CORRECT USE
OF THE CAR
For the electric connection a unified con-
nector should be used which is gener-
ally placed on a special bracket normally
fastened to the towing device.
For the electrical connection, 7 pin
12VDC connection is to be used (CU-
NA/UNI and ISO/DIN Standards). Fol-
low the instructions provided by the car
manufacturer and/or the tow hitch man-
ufacturer.
An electric brake or other device (elec-
tric winch, etc.), if required, should be
supplied directly by the battery through
a cable with a cross section of no less
than 2.5 mm
2. In addition to the elec-
trical branches, the car’s electric system
can only be connected to the supply ca-
ble for an electric brake and to the ca-
ble for an internal light, though not
above 15W.Assembly diagram fig. 4
The structure of the tow-hook must be
fixed in the indicated points with
Øwith
n. 2 M10 screws and n. 4 M12 screws.
The fixing points (1) must be provided
with Ø 25x6 mm spacers.
The counter-plates (2) must have a min-
imum thickness of 4 mm.
The counter-plates (3) must have a min-
imum thickness of 6 mm.
IMPORTANTIt is compulsory to fas-
ten a label (plainly visible) of suitable
size and material with the following
wording:
MAX LOAD ON BALL 75 kg
After fitting, screw holes shall be sealed
to prevent exhaust gas inlet.
IMPORTANTThe hook should be fas-
tened to the body avoiding any type of
drilling and trimming of the bumper.
INSTALLING THE TOW HOOK
The towing device should be fastened
to the body by specialised personnel ac-
cording to any additional and/or inte-
grative information supplied by the Man-
ufacturer of the device.
The towing device must meet current
regulations with reference to 94/20/EC
Directive and subsequent amendments.
For any version the towing device used
must match the towable weight of the
car on which it is to be installed.

Due to the snow tyre features, under
normal conditions of use or on long mo-
torway journeys, the performance of
these tyres is lower than that of normal
tyres. It is therefore necessary to limit
their use to the purposes for which they
are certified.
IMPORTANTWhen snow tyres are
used with a max speed index below the
one that can be reached by the car (in-
creased by 5%), place a notice in the
passenger compartment, plainly in the
driver’s view which states the max per-
missible speed of the snow tyres (as per
EC Directive).
All four tyres should be the same (brand
and track) to ensure greater safety
when driving and braking and better dri-
veability.
Remember that it is inappropriate to
change the direction of rotation of tyres.SNOW TYRES
Use snow tyres of the same size as the
normal tyres provided with the car.
Alfa Romeo Authorized Services will be
glad to provide advice concerning the
most suitable type of tyre for the cus-
tomer’s requirements.
For the type of tyre to be used, inflation
pressures and the specifications of snow
tyres, follow the instructions given in para-
graph “Wheels” in section “Technical
specifications”.
The winter features of these tyres are re-
duced considerably when the tread
depth is below 4 mm. In this case, they
should be replaced.
The max speed for
snow tyres with “Q”
marking is 160 km/h; 190
km/h for tyres with “T”
marking and 210 km/h for
tyres with H marking. The
Road Traffic Code speed lim-
its must however be always
strictly observed.

IMPORTANTSnow chains cannot be
fitted to the space-saver spare wheel.
So, if a front (drive) wheel is punctured
and chains are needed, a rear wheel
should be fitted to the front of the car
and the spare wheel should be fitted to
the rear (adjust tyre pressure to the spec-
ified value as soon as possible). This
way with two normal drive wheels,
snow chains can be fitted to them to
solve an emergency.
Also for 3.2 JTS version,
snow chains shall be fit-
ted on the FRONT axle of
the car.
SNOW CHAINS
Use of snow chains should be in compli-
ance with local regulations.
Snow chains should only be applied to
the driving wheels (front wheels).
Check the tension of the chains after the
first few metres have been driven.
Use snow chains with reduced size: for
tyres 205/55 R16” and 215/55
R16” use snow chains with reduced size
with max protrusion beyond the tyre pro-
file of 9 mm.
Use of snow chains may be compulso-
ry also for cars with four-wheel drive.
Traditional snow chains
may not be used on tyres
type 225/50 R17” on-
ly spider type chains can be used.
Tyres 235/45 R18” and
235/40 ZR 19” cannot be fitted
with snow chains due to inter-
ference with the fender.
Keep your speed down
when snow chains are
fitted. Do not exceed
40 km/h. Avoid pot-
holes, steps and pave-
ments and avoid also to drive
for long distances on roads not
covered with snow to prevent
damaging the car and the
roadbed.
WARNING
When snow chains are
fitted, switch the ASR
system off. Press the
ASR/VDC button (see para-
graph “ASR system” in section
“Dashboard and controls”).

CAR INACTIVITY
If the car is to be left inactive for longer
than a month, the following precautions
should be noted:
❒ park the car in covered, dry and if
possible well-ventilated premises;
❒ engage a gear;
❒check that the handbrake is not en-
gaged;
❒disconnect battery negative terminal
and check the battery charge. This
check is to be repeated every three
months when the car is left inactive.
Recharge if the optical(where pro-
vided) indicator shows a dark colour
without the central green area (see
paragraph “Battery” in “Car main-
tenance” section);
❒clean and protect the painted parts
using protective wax;
❒clean and protect the shiny metal
parts using special compounds read-
ily available;
❒sprinkle talcum powder on the rubber
windscreen and rear window wiper
blades and lift them off the glass;
❒slightly open the windows;
❒cover the car with a cloth or perfo-
rated plastic sheet. Do not use sheets
of non-perforated plastic as they do
not allow moisture on the car body
to evaporate;
❒inflate tyres to +0.5 bar above the
normal specified pressure and check
it at intervals;
❒if you don’t disconnect the battery
from the electric system, check its
charge every month and recharge it
if the optical indicator shows a dark
colour without the central green area;
❒ do not drain the engine cooling sys-
tem.
IMPORTANTIf the car is fitted with
alarm system, switch off the alarm with
the remote control.
