IMPORTANT
If at start-up the engine turns off, restart
it by pressing the clutch or brake pedal
and then press button START/STOP.
If after a few attempts the engine does
not start, do not insist but contact Alfa
Romeo Authorized Services.
With car started the electronic key is
locked into the ignition device and it can
be removed only after switching the en-
gine off. With car running and key
locked into the ignition device, forced
key removal could damage the ignition
device.
Start-up failures, if any, are indicated by
the turning on of the warning light
Y
on the instrument panel (on certain ver-
sions a dedicated message is displayed).
In this case contact Alfa Romeo Autho-
rized Services.
If the engine will not start after pressing
buttonSTART/STOP, repeat the
start-up procedure by pressing the oth-
er pedal (clutch or brake). Start-up failures
The system can recognise start-up fail-
ures.
In the event of failure, the electronic key
can be removed from the ignition device to
enable the driver to carry out the follow-
ing operations:
❒turn the instrument panel off by
pressing button START/STOPor
removing the electronic key from the
ignition device;
❒start the engine again by pressing the
clutch/brake pedal and button
START/STOP.
IMPORTANT In the event of engine
locking while the car is running, due to
safety reasons it will not be possible to
take the electronic key out of the igni-
tion device. To remove it, press button
START/STOPwith brake pedal (or
clutch pedal) released and car stopped.
HOW TO WARM UP THE
ENGINE AFTER IT HAS
JUST STARTED
(petrol and diesel engines)
Proceed as follows:
❒Drive off slowly, letting the engine
turn at medium revs. Do not acceler-
ate abruptly;
❒Do not drive at full performance for
the initial kilometres. Wait until the
coolant temperature gauge starts
moving.

OF THE CAR
IMPORTANTAfter a taxing drive, you
should allow the engine to “catch its
breath” before turning it off by letting it
idle to allow the temperature in the en-
gine compartment to fall.
IMPORTANTTurning the car off will
deactivate the electronic safety systems
and turn off the external lights.IMPORTANTIn the event of engine
locking while the car is running, due to
safety reasons it will not be possible to
take the electronic key out of the igni-
tion device. To remove it, turn the in-
strument panel on and off by pressing
buttonSTART/STOPwith brake ped-
al (and clutch pedal) released and car
stopped.
REMOVING THE ELECTRONIC
KEY FROM THE IGNITION
DEVICE IN AN EMERGENCY
In the event of a failure at engine switch-
ing off system or at electronic key un-
locking system proceed as follows:
❒press the unlocking button to remove
the metal insert (see paragraph
“Electronic key” in section “Dash-
board and controls”);
STOPPING THE ENGINE
With car stopped press button START/
STOP. When the engine is off it will be
possible to remove the electronic key
from the ignition device.
A quick burst on the ac-
celerator before turning
off the engine serves
absolutely no practical purpose,
it wastes fuel and is damaging
especially to turbocharged en-
gines.❒fit the metal insert B-fig. 1of the
electronic key into the slot A;
❒remove the electronic key from the
ignition device.
IMPORTANTOnly fit the metal insert
Bof the electronic key into slot A-fig.1.
IMPORTANTStop the car before
emergency removal of the key, since re-
moving the key with the engine running
will turn both the engine and the in-
strument panel off and the steering lock
will not be engaged.
A0E0043mfig. 1In an emergency, and
for safety reasons the
engine can be turned off when
the car is running by pressing
repeatedly (3 times within
2 seconds) or by keeping
pressed button START/STOP
for a few seconds. In this case
the steering lock cannot be en-
gaged.

PARKING THE CAR
Proceed as follows:
❒Stop the engine and engage the
handbrake;
❒Engage a gear (on a slope, engage
first gear if the car is faced uphill or
reverse if it is faced downhill) and
leave the wheels steered.
Block the wheels with a wedge or a stone
if the car is parked on a steep slope. Do
not leave the electronic key in the igni-
tion switch to prevent draining the bat-
tery.
Never leave children un-
attended in the car. Al-
ways remove the electronic key

OF THE CARTo engage reverse Rfrom neutral, raise
ringA-fig. 3under the knob and at
the same time move the gearshift lever
leftwards and then forward. After en-
gaging reverse release the ring. To shift
from reverse to another gear it is not
necessary to raise the ring.
IMPORTANT The car can only be put
into reverse gear when it has stopped
moving completely. With the engine run-
ning, before engaging the reverse, wait
at least 3 seconds with the clutch ped-
al fully down to prevent damage and
grating of the gears.
A0E0151mfig. 3
To change gears prop-
erly you must push the
clutch pedal fully down. It is
therefore essential that there
is nothing under the pedals:
make sure mats are lying flat
and do not get in the way of
the pedals.
WARNING
Do not drive with your
hand resting on the gear
lever as the force ex-
erted, even if slight, could lead
over time to premature wear on
the gearbox internal compo-
nents.
USING THE
GEARBOX
The car is fitted with 6-gear manual
gearbox. Gear positions are shown on
the gearshift lever knob.
Always press down the clutch pedal
when shifting gears. To engage the 6
th
gear, move the gearshift lever pressing
slightly rightwards to prevent engaging
the 4
thgear accidentally.

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.

CORRECT USE
OF THE CAR
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.

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 indicator
shows a dark colour without the cen-
tral green area (see paragraph “Bat-
tery” in “Car maintenance” 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.
