redENGINE COOLANT TEMPERATURE
TOO HIGH
The digital warning light switches on when
the key is turned to MAR-ON, but it should
switch off after a few seconds. The warning
light switches on when the engine is
overheated.
The display shows the dedicated message.When driving normally: stop the car, switch off the
engine and check that the water level in the reservoir is
not below the MIN mark. If it is, wait for the engine to
cool down then slowly and carefully open the cap, top
up with coolant and check that the level is between the
MIN and MAX marks on the reservoir. Also check
visually for any fluid leaks. Should the warning light turn
on again at the next start-up, contact the dedicated
Alfa Romeo Dealership.
If the car is used under demanding conditions (e.g. in
high-performance driving): slow down and, if the
warning light stays on, stop the car. Wait for 2 or 3
minutes with the engine running and slightly
accelerated to further favour the coolant circulation.
Then stop the engine. Check the correct coolant level
as described above.
IMPORTANT Over demanding routes, it is advisable to
keep the engine on and slightly accelerated for a few
minutes before switching it off.

❒If it is necessary to proceed downhill
with transmission in neutral (N) for
unexpected reasons, bearing in mind
that this practice is highly inadvisable,
remember that when gear
engagement is requested, the
system will automatically engage the
best gear to permit the correct
transmission of drive torque to the
wheels, according to the speed
of the car.
❒When necessary, it is possible to
engage 1st gear, reverse (R)or
neutral (N) with the engine off, the
key at MAR-ON and the brake
pressed. In this case, change gear
leaving at least 5 seconds between
one gear change and the next, in
order to safeguard the operation of
the hydraulic system, and the pump
in particular.
❒For uphill departures, it is advisable
to accelerate gradually but fully
immediately after releasing the
handbrake or the brake pedal; this
allows the engine to temporarily
increase the number of revs and
tackle the steepest gradients with
more torque at the wheels.
WARNING
89) The Launch control function is
only available in Race mode.
Regardless of what is explicitly
indicated in the description of this
mode, the ESC and ASR systems
are deactivated during operation
of the Launch Control function.
This means that vehicle dynamic
control is the sole responsibility of
the driver. Therefore pay the
utmost attention when using the
Launch Control. Take into account
traffic and road surface conditions
and during manoeuvres make
sure there is enough room in the
area concerned.
SAVING FUEL
Alfa Romeo has designed and built the
vehicle using technologies, materials
and devices able to reduce negative
environmental impact. Here are some
suggestions to further contribute to
environmental protection.
GENERAL
CONSIDERATIONS
Car maintenance
Have checks and adjustments carried
out in accordance with the “Scheduled
Servicing Plan”.
Tyres
Check the tyre pressures at least once
every four weeks: if the pressure is
too low, consumption levels increase as
resistance to rolling is higher.
Climate control system
The use of the climate control system
leads to higher fuel consumption. If the
temperature outside permits, try to
use ventilation only.
111

IMPORTANT
11) Keep your speed down when
snow chains are fitted; do not
exceed 50 km/h. Avoid potholes,
steps and pavements and avoid
driving for long distances on
roads not covered with snow to
prevent damaging the car and the
road surface.
CAR INACTIVITY
If the vehicle is to be left inactive for
longer than a month, observe the
following precautions:
❒park the car in covered, dry and if
possible well-ventilated premises and
slightly open the windows;
❒check that the handbrake is not
engaged;
❒disconnect the negative battery
terminal and check the battery
charge. Repeat this check once
every three months during storage.
For optimum preservation of the
battery charge, it is advisable to use
the charge-holder (for versions/
markets, where provided, or
alternatively, available from
Lineaccessori). For more details on
its operation, refer to the attached
Supplement;
❒if the battery is not disconnected
from the electrical system, checks its
state of charge every thirty days;
❒clean and protect the painted parts
using protective wax;❒sprinkle talcum powder on the rubber
blade of the windscreen wiper and lift
it off the glass (for the correct lifting
procedure, refer to the "Windscreen
wiper" paragraph in the
"Maintenance and care" chapter);
❒cover the car with a cloth or
perforated 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
standard prescribed pressure and
check it periodically;
❒do not drain the engine cooling
system;
❒every time the car is left inactive for
two weeks or longer, run the air
conditioning system for about
5 minutes, set to outside air and with
fan set to maximum, with the engine
idling; this operation will ensure
adequate lubrication to minimise the
possibility of damage to the
compressor when the system is put
back into operation;

STARTING AND DRIVING

STARTING THE
ENGINE
Contact the dedicated Alfa Romeo
Dealership immediately if
warning
light stays on constantly on the
instrument panel.
JUMP STARTING
If the battery is flat, start the engine
using an auxiliary battery with the same
capacity or a little higher than the flat
one.
12)91)
Proceed as follows to start the car:
❒connect the positive terminals (+ sign
near the terminal) of the two batteries
with a jump lead fig. 79;❒with a second lead, connect the
negative terminal(−)oftheauxiliary
battery to an earthing point
on
the engine or the gearbox/
transmission of the car to be started;
❒start the engine; when the engine has
started, remove the leads, reversing
the order above.
If after a few attempts the engine does
not start, do not persist but contact
the dedicated Alfa Romeo Dealership.
IMPORTANT Do not connect the
negative terminals of the two batteries
directly! If the auxiliary battery is
installed on another car, check that
there is no accidental contact between
metallic parts of the two cars.
BUMP STARTING
Never, under any circumstances, jump
start the engine by pushing, towing
or coasting downhill.
IMPORTANT
12) Never use a fast battery charger
to start the engine as this could
damage the electronic systems
and the ignition and engine supply
control units.
WARNING
91) This procedure must be
performed by qualified personnel
as incorrect actions may cause
high-intensity electrical discharge.
Furthermore, battery fluid is
poisonous and corrosive: avoid
contact with skin and eyes. Keep
naked flames and lit cigarettes
away from the battery and do not
cause sparks.

REPLACING FUSES
GENERAL INFORMATION
Fuses protect the electrical system:
they intervene (blow) in the event of a
fault or improper action on the system.
When a device does not work, check
the condition of its fuse: the filament
A fig. 110 must be intact.
If it is not, replace the blown fuse with
another with the same amperage (same
colour).
110) 111) 112) 113) 114)16)
B = intact fuse;
C = fuse with damaged filament.FUSE LOCATION

WARNING
115) Before towing, turn the ignition
key to MAR-ON and then to STOP
without removing it. The steering
column will automatically lock
when the key is removed and the
wheels cannot be steered. Also
check that the gearbox/
transmission is in neutral (N).
116) When towing, remember that
the assistance of the brake servo
is absent. Consequently, more
force is required at the pedal
in order to brake. Do not
use flexible cables when towing
and avoid jerky movements. Make
sure not to damage parts in
contact with the car while towing.
When towing the car, you must
comply with all specific traffic
regulations, both in terms of the
towing device and behaviour
on the road. Do not start the
engine while towing the car.
Before tightening the ring, clean
the threaded housing thoroughly.
Make sure that the ring is fully
screwed into the housing before
towing the car.117) The tow hook must be used
exclusively for roadside
assistance operations. You are
allowed to tow the vehicle for
short distances using an
appropriate device in accordance
with the highway code (a rigid
bar), to move the vehicle on the
road in readiness for towing or
transport via a breakdown vehicle.
Tow hooks MUST NOT be used
to tow vehicles off the road or
where there are obstacles and/or
for towing operations using cables
or other non-rigid devices. In
compliance with the above
conditions, towing must take
place with the two vehicles (one
towing, the other towed) aligned
as much as possible along the
same centre line.
