ELECTRIC POWER STEERING
This only works with the key turned to MAR and the engine start-
ed. Power steering allows the force required at the steering wheel
to adapt to driving conditions.
The different power assistance modes can be selected via the d,n,a
positions of the“Alfa DNA System” lever (see paragraph “Alfa DNA
System”).
EOBD SYSTEM
(for versions/markets, where provided)
The aim of the EOBD system (European On Board Diagnosis) is to:
❍keep the system efficiency under control;
❍indicate an increase in emissions;
❍indicate the need to replace deteriorated components.
The vehicle also has a diagnostic connector that can be interfaced
with appropriate tools, which makes it possible to read the error
codes stored in the electronic control units together with a series
of specific parameters for engine operation and diagnosis. This check
can also be carried out by the traffic police.
IMPORTANT After eliminating a fault, to check the system com-
pletely, Alfa Romeo Authorised Services are obliged to run tests
and, if necessary, road tests which may also call for a long journey.
It is absolutely forbidden to carry out any after-
market operation involving steering system or
steering column modifications (e.g.: installation of
anti-theft device). This could badly affect performance and
safety, invalidate the warranty and also result in the non-
compliance of the car with approval requirements.
Before carrying out any maintenance operation
switch off the engine and remove the ignition key
to activate the steering lock. This is particularly im-
portant if the vehicle’s wheels are raised from the ground.

T.P.M.S. SYSTEM (Tyre Pressure
Monitoring System)
(for versions/markets, where provided)
The vehicle can be fitted with a tyre pressure monitoring system
(T.P.M.S.), which informs the driver of the tyre inflation pressure
via the “Check the tyre inflation pressure” and “Insufficient tyre in-
flation pressure” warning messages.
This system comprises of a radio frequency transmitter fitted to
each wheel (on the wheel rim inside the tyre), which is able to
send information on the tyre inflation pressure of each wheel to
the control unit.
IMPORTANT NOTES ABOUT
THE T.P.M.S. SYSTEM
The fault indications are not stored and will therefore not be dis-
played after the engine has been switched off and then on again.
If the fault conditions persist, the control unit will send fault infor-
mation to the instrument panel only after the vehicle has been in
motion for a short time.
Take the greatest of care when checking and top-
ping up the tyre inflation pressure. Excessive pres-
sure compromises road holding, increases the stress
on the suspension and wheels as well as increasing the risk
of the tyres wearing out un-evenly.
The tyre inflation pressure should be measured
with the tyres at rest and cold; if for any reason
the pressure is checked when the tyres are warm,
do not reduce the pressure if it is excessive but rather wait
until the tyres have cooled down and carry out the check
again.
The presence of the T.P.M.S. system does not mean
the driver should not carry out regular checks on
the tyre inflation pressure and spare wheel.
Should one or more wheels be fitted without sen-
sors, the display will show a warning message and
the system will no longer be available until 4
wheels fitted with sensors are fitted.

The expiry dates of the pyrotechnic charge and spi-
ral contact are shown in the plate installed inside
the glove compartment. Refer to an Alfa Romeo
Authorised Services when it’s time to replace them.
Do not travel with objects on your lap, in front of
your chest, or between your lips (e.g. pipes, pen-
cils, etc.) In the event of a crash with airbag acti-
vation, you may be seriously injured.
If someone tries to steal or damage your car, and
in the event of floods, have the air bag system
checked by an Alfa Romeo Authorised Services.
With the ignition key inserted and turned to MAR,
even if the engine is off, the air bags can activate
also with the car at a standstill, if it is hit by an-
other vehicle. For this reason, children must never sit on
the front seat, even if the car is not moving. Please re-
member that if the key is inserted and turned to the STOP
position, no safety device (airbag or pretensioner) acti-
vates following a collision. Non-deployment in such cas-
es must not be considered a sign of malfunction.
When the ignition key is turned to MAR, the “
warning light turns on (front airbag on passenger’s
side enabled) and blinks for a few seconds as a re-
minder that the passenger airbag will activate in the event
of a collision. Then it turns off.
The front airbags deploy in the event of more se-
vere collisions than those required for deploying
the pretensioners. For collisions in the range be-
tween the two thresholds, it is normal for only the pre-
tensioners to be activated.

158STARTING UP AND DRIVING
SAVING FUEL
Here are some suggestions which may help you to save fuel and
lower the amount of toxic emissions released into the atmosphere.
GENERAL CONSIDERATIONS
Car maintenance
Have checks and adjustments carried out in accordance with the
“Scheduled servicing plan”.
Tyres
Check tyre pressure regularly, at least once every four weeks: ex-
cessively low pressure will increase fuel consumption because rolling
resistance will be higher.
Unnecessary loads
Do not travel with an overloaded boot. The weight of the car and
its ride setting greatly affect fuel consumption and stability.
Press the clutch pedal fully to change gears cor-
rectly. For this reason, there must be no obstacles
on the floor under the pedals: ensure that any rub-
ber mats are correctly positioned, and do not interfere
with the pedals
Do not drive with your hand resting on the gear
lever, because this pressure, even if light, can wear
out the gearbox internal components over time.
IMPORTANT Reverse may only be engaged when the car is at a
standstill. With the engine on, wait at least 3 seconds with the
clutch pressed down before engaging reverse gear to prevent it
from scraping.

162STARTING UP AND DRIVING
SNOW CHAINS
The use of snow chains should be in compliance with local regu-
lations. The snow chains may be applied only to the front wheel
tyres (drive wheels).
Check the tension of the chains after the first few metres have been
driven.
Use reduced bulk snow chains: for 195/55 R16” and 205/45
R17” tyres. Use reduced bulk snow chains with a maximum pro-
trusion from the tyres of 9 mm.
IMPORTANT The spare wheel cannot be fitted with snow chains.
If a front (drive) wheel is punctured and snow chains must be used,
you must remove a normal wheel from the rear and replace this
one with the small spare wheel. In this way, with two normal dri-
ve wheels, it is possible to use snow chains.
CAR INACTIVITY
If the car is to be left inactive for longer than a month, the following
precautions should be noted:
❍park the vehicle in a dry, covered and, if possible, ventilated
area; engage a gear and check that the handbrake is not en-
gaged;
❍disconnect the negative battery terminal and check battery
charge. Repeat this check once every three months during stor-
age;
❍clean and protect painted areas using protective wax;
❍clean and protect the shiny metal areas using special com-
mercially-available products;
❍sprinkle talcum powder on the rubber windscreen and rear win-
dow wiper blades and lift them off the glass;
❍slightly open the windows;
❍cover the car with a fabric or perforated plastic sheet. Do not
use compact plastic sheets which do not allow humidity to evap-
orate from the surface of the car.
❍inflate tyres to a pressure of +0.5 bar above the normal spec-
ified pressure and check the pressure at regular intervals;
❍if you have not disconnected the battery, check the battery
charge every thirty days;
❍do not drain the engine cooling system.
Keep your speed down when snow chains are fit-
ted. Do not exceed 50 km/h. Avoid potholes, steps
and pavements and also avoid driving long dis-
tances on roads not covered with snow to prevent dam-
aging the car and the roadbed.

176IN AN EMERGENCY
❍if a pressure value of a least 1.8 bars is not reached within 5
minutes, disconnect the compressor from the valve and current
socket, move the vehicle forwards by about 10 metres to dis-
tribute the sealant fluid in the tyre and repeat the inflation
procedure;
fig. 18A0J0116m
❍if a pressure value of a least 1.8 bars is not reached within 5
minutes of switching on the compressor, do not continue dri-
ving. Contact an Alfa Romeo Authorised Services;
❍after having driven for about 10 minutes, stop the car and check
the tyre pressure once more: remember to engage the hand-
brake;
❍if a pressure value of at least 1.8 bars is detected, restore the
correct pressure (with the engine running and the handbrake
engaged), and drive with care to an Alfa Romeo Authorised
Services.
Apply the adhesive label where it can be easily
seen by the driver as a reminder that the tyre has
been treated with the quick repair kit. Drive care-
fully, particularly on bends. Do not exceed 80 km/h. Do
not accelerate or brake suddenly.If the pressure has fallen below 1.8 bar, do not
drive any further: the Fix & Go automatic quick
tyre repair kit cannot guarantee proper hold be-
cause the tyre is too damaged. Contact an Alfa Romeo
Authorised Services.
Remember to inform the workshop that the tyre
has been treated with a quick repair kit. Give the
instruction booklet to the personnel charged with
handling the treated tyre.
