BATTERY RECHARGING
IMPORTANT NOTES
166) 167)
IMPORTANT Before using the charging
device, always make sure that it is
appropriate for the installed battery,
with constant voltage (below 14.8 V) and
low amperage (maximum 15 A).
IMPORTANT Recharge the battery in a
well ventilated environment.
IMPORTANT Never charge or recharge a
frozen battery: it may explode because
of the nitrogen trapped inside the ice
crystals.
IMPORTANT At all times while charging
or recharging the battery, make sure that
any sparks or open flames are kept
sufficiently far away from the battery.
IMPORTANT Before using any devices to
charge or to maintain the charge of the
battery, carefully follow the instructions
provided with the device in order to
properly and safely connect it to the car
battery.
You can recharge the battery without
disconnecting the wires of the vehicle's
electrical system.
To reach the battery, remove the
access panel inside the boot fig. 156;
remove the protective cover 1
fig. 157 and connect the positive cable
terminal of the charger (usually red) to
the positive terminal (+) of the battery;
connect the negative terminal of the
charger (usually black) to nut 2 next to
the negative terminal (-) of the battery, as
shown in fig. 157;
The vehicle is equipped with an IBS
(Intelligent Battery Sensor), which is able

This function can only be activated within
2 minutes of setting the ignition device
to STOP.
To activate this function, move the lever
upwards (unstable position) for at least
three seconds.
If, after using the function, the ignition
device is set back to ON with the blades
in a position other than rest position (at
the base of the windscreen), they will only
return to rest position following a
command given using the stalk (stalk
upwards, into unstable position) or when
a speed of 3 mph (5 km/h) is exceeded.
Replacing the windscreen wiper blades
Proceed as follows:
raise the wiper arm, press tab
fig. 159 of the attachment spring and
remove the blade from the arm;
fit the new blade, inserting the tab in
the dedicated housing in the arm and
checking that it is locked;
lower the wiper arm onto the
windscreen.
IMPORTANT Do not operate the
windscreen wiper with the blades lifted
from the windscreen.
Windscreen washer
The window washer nozzles are fixed. If
there is no jet of fluid, firstly check that
there is fluid in the reservoir (see
paragraph “Engine compartment” in this
chapter).
Then check that the nozzle holes are not
clogged; use a needle to unblock them if
necessary.
WARNING
168)The air intake system (air cleaner,
rubber hoses, etc.) can be a protection in the
case of blowbacks from the engine. DO NOT
REMOVE this system unless you need to
carry out repair or servicing operations.
Before starting the engine, ensure that the
system has not been removed: failure to
observe this precaution may result in serious
injury.
169)Exhaust emissions are very dangerous,
and may be lethal. They contain carbon
monoxide, a colourless, odourless gas which
can cause fainting and poisoning if inhaled.
170)The exhaust system may reach high
temperatures and may cause a fire if the
vehicle is parked on flammable material. Dry
grass or leaves can also catch fire if they
come into contact with the exhaust system.
Do not park or use the vehicle in a place in
which the exhaust system might come into
contact with flammable material.
IMPORTANT
72)Incorrect servicing of the vehicle or
failure to carry out operations or repairs
(when necessary) may lead to more
expensive repairs, damage to other
components or have a negative impact on
the vehicle performance. Have any
malfunction inspected immediately by an
Alfa Romeo Dealership.

73)The vehicle is equipped with fluids which
are optimised or protecting its performance
and life and extending service intervals. Do
not use chemicals for washing these
components since they may damage the
engine, the transmission or the climate
control system. This damage is not covered
by the vehicle’s warranty. If any component
needs to be washed due to malfunctioning,
use only the specific liquid for that
procedure.
74)An excessive or insufficient amount of
oil inside the base is extremely damaging to
the engine. Make sure it is always at an
adequate level.
75)Vehicles equipped with catalytic
converter must be fuelled only with unleaded
petrol. Leaded petrol would permanently
damage the catalytic converter and
eliminate its ability to reduce polluting
emissions, seriously compromising the
engine performance, which would be
irreparably damaged. If the engine does not
work correctly, especially if it starts
irregularly or if there is a reduction of its
performance, immediately go to an Alfa
Romeo Dealership. Prolonged and faulty
operation of the engine may cause
overheating of the converter and, as a
consequence, possible damage to the
converter and the vehicle.
76)Using a gearbox fluid different from that
approved may compromise gearshifting
quality and/or cause vibration of the
gearbox itself.77)It is recommended to have the vehicle
serviced by an Alfa Romeo Dealership. When
carrying out normal periodic operations and
small servicing interventions personally on
the vehicle, it is recommended to use
suitable equipment, genuine spare parts and
the necessary fluids. Do not carry out any
interventions if you don't have the necessary
experience.
78)When you need to disconnect or remove
the battery, do not close the boot. Open the
boot manually if it is locked.
79)Always require the use of only
compressor coolants and lubricants
approved and suitable for the specific air
conditioning system fitted on the vehicle.
Some non-approved coolants are flammable
and may explode, with the risk of injuries. The
use of non-approved coolants or lubricants
may adversely affect system efficiency,
leading to expensive repairs.
80)The air conditioner system contains
coolant under high pressure: to avoid injuries
to people or damage to the system, any
coolant addition or repair that requires to
disconnect the cables must be carried out by
an Alfa Romeo Dealership.LIFTING THE VEHICLE
If the car needs to be jacked up, go to an
Alfa Romeo Dealership which is equipped
with shop jacks or jack arms.
The vehicle lifting points are marked on
the side skirts with the
symbols (see
illustration in fig. 160 ).

SERVICING AND CARE

IMPORTANT
81)Keep your speed down when snow chains
are fitted; do not exceed 50 km/h (or the
equivalent in miles). Avoid potholes, do not
drive over steps or pavements and do not
drive long distances over roads without
snow, to avoid damaging both your vehicle
and the road surface.
BODY
PRESERVING THE BODYWORK
Paintwork
82)7)
Touch up abrasions and scratches
immediately to prevent the formation of
rust.
Some parts of the car may be covered
with a matt paint which, in order to be
maintained intact, requires special care:
see the instructions in the warning at the
end of this paragraph.
83)
To correctly wash the vehicle, follow
these instructions:
if high pressure jets or cleaners are
used to wash the vehicle, hold at least
16 in [40 cm] away from the bodywork to
avoid damage or alteration. Build up of
water could cause damage to the car in
the long term;
to make it easier to remove any dirt
deposits in the area where the blades are
normally located it is recommended to
position the windscreen wipers vertically
(service position), for more information
consult the “Maintenance procedures”
paragraph in this chapter.If you want to wash a car with automatic
transmission in a car wash that moves it,
you must do the following:
make sure that the car is on a flat
surface and that automatic engagement
of the parking brake when the engine is
switched off is disabled (for how to
disable it, refer to the “Electric parking
brake” section in the “Starting and
driving” chapter);
with the car stationary, the gear in N
(Neutral) and the brake pedal up: press
the start button.The car will remain in N
(Neutral) for 15 minutes, after which P
(Park) mode will be activated.
IMPORTANT
82)In order to preserve the aesthetic
appearance of the paint abrasive products
and/or polishes should not be used for
cleaning the vehicle.

COLD TYRE INFLATION PRESSURE
When the tyres are warm, the inflation pressure should be +4.35 psi (+0.3 bar) in relation to the recommended figure. However,
recheck that the value is correct with the tyre cold.
If it is necessary to raise the vehicle, refer to the "Raising the vehicle" paragraph in the "In an emergency" chapter.
The pressures given below apply to all tyre types: summer, winter and all season (where provided).
