SERVICING AND MAINTENANCE
Correct servicing permits the performance of the
vehicle to be maintained over time, as well as
limited running costs and safeguarding the
efficiency of the safety systems.
This chapter explains how.
SCHEDULED SERVICING
Correct servicing is crucial for guaranteeing a
long life for the vehicle under the best conditions.
For this reason, Alfa Romeo has planned a series
of checks and services for your vehicle at fixed
intervals based on distance and time, as
described in the Scheduled Servicing Plan.
Before each service, it is always necessary to
carefully follow the instructions in the Scheduled
Servicing Plan (e.g. periodically check level of
fluids, tire pressure, etc.).
Scheduled Servicing is offered by an authorized
dealer according to a set time schedule. If, during
each operation, in addition to the ones
scheduled, the need arises for further
replacements or repairs, these may be carried
out with the owner’s explicit consent only.

NOTE:
Scheduled Servicing intervals are required by the
manufacturer. Failure to have them carried out
may invalidate the New Vehicle Limited Warranty.
You are advised to inform an authorized dealer of
any small operating irregularities without waiting
for the next service.
PERIODIC CHECKS
Every month or every 600 miles (1,000 km) or
before long trips check and, if necessary, top off:
Engine coolant level.
Brake fluid level (if insufficient, see an
authorized dealer as soon as possible).
Windshield washer fluid level.
Tire inflation pressure and condition.
Operation of lighting system (headlights,
direction indicators, hazard warning lights,
etc.).
Operation of windshield washing/wiping
system and positioning/wear of wiper blades.
Inspect the CV/Universal joints.
Oil consumption of the engine depends on
conditions and driving style. For this reason, the
engine oil level must be checked every
1,860 miles (3,000 km), and top off if necessary

Ú
page 188.
HEAVY USAGE OF THE VEHICLE
If the vehicle is used under one of the following
conditions:
Dusty roads.
Short, repeated journeys less than 4 miles
(7 km) at sub-zero outside temperatures.
Engine often idling or driving long distances at
low speeds or long periods of inactivity.
In the event of a long period of inactivity. The following checks must be carried out more
often than indicated in the Scheduled Servicing
Plan:

NOTE:
The headlight washing system will not work if the
liquid level is low (as indicated by the symbol on
the instrument cluster display). On vehicles
equipped with headlight washers, there is a refer-
ence notch on the dipstick: ONLY the windshield/
rear window washer operates with the level below
this reference.
BRAKE FLUID
Check that the fluid is at the maximum level. If
the fluid level in the tank is low, contact an
authorized dealer to have the system checked.
AUTOMATIC TRANSMISSION ACTIVATION
S
YSTEM OIL
The transmission control oil level should only be
checked at an authorized dealer.
USEFUL ADVICE FOR EXTENDING THE
L
IFE OF YOUR BATTERY
To avoid draining your battery and make it last
longer, observe the following instructions:
When you park the car, ensure that the doors
and trunk are closed properly to prevent any
lights from remaining on inside the
passenger's compartment.
Do not keep accessories (e.g. radio, hazard
warning lights, etc.) switched on for a long time
when the engine is not running.
Before performing any operation on the
electrical system, disconnect the negative
battery cable. If you wish to install electrical accessories after
purchasing the car that require permanent
electrical supply (e.g. alarm, etc.), or accessories
which influence the electrical supply
requirements, contact an authorized dealer,
whose qualified staff will evaluate the overall
electrical consumption.

NOTE:
After the battery is disconnected, the steering
must be initialized. The warning light on the
instrument panel switches on to indicate this. To
carry out this procedure, simply turn the steering
wheel all the way from one end to the other, and
then turn it back to the central position.
BATTERY
The battery does not require the electrolyte to be
topped up with distilled water. A periodic check
carried out at an authorized dealer, however, is
necessary to check efficiency.
Follow the battery manufacturer's instructions for
maintenance.
Replacing The Battery
If necessary, replace the battery with another
original battery with the same specifications.
Follow the battery manufacturer’s instructions for
maintenance.
NOTE:
It will not be possible to open the trunk with a key
or by pushing the button in the passenger
compartment when the battery is disconnected.
So, always position the manual trunk opening
strap on the trunk lock before disconnecting the
battery

Ú
page 220.
CAUTION!
If the charge level remains under 50% for a
long time, the battery may be damaged by
sulphation, reducing its capacity and
efficiency during a vehicle start. The battery is
also more prone to the risk of freezing (at
temperatures as high as 14°F (-10°C).
WARNING!
Battery acid is a corrosive solution and can
burn or even blind you. Do not allow battery
acid to contact your eyes, skin, or clothing.
Do not lean over a battery when attaching
clamps

Ú
page 177. If acid splashes in eyes
or on skin, flush the area immediately with
large amounts of water.
Battery gas is flammable and explosive.
Keep flame or sparks away from the battery.
Do not use a booster battery or any other
booster source with an output greater than
12 Volts. Do not allow cable clamps to touch
each other.
Battery posts, terminals, and related
accessories contain lead and lead
compounds. Wash hands after handling.

LUBRICATING MOVING PARTS OF THE
B
ODYWORK
Ensure that the locks and bodywork junction
points, including components such as the seat
guides, door hinges (and rollers), trunk and hood
are periodically lubricated with lithium-based
grease to ensure correct, silent operation and to
protect them from rust and wear.
Thoroughly clean the components, eliminating
every trace of dirt and dust. After lubricating,
eliminate excess oil and grease. Also pay
particular attention to the hood closing devices,
to ensure correct operation. During operations on
the hood, to be carried out with the engine cold,
also remember to check, clean and lubricate the
locking, release and safety devices.
Lubricate the external lock barrels twice a year.
Apply a small amount of high-quality lubricant
directly into the lock barrel.
If necessary, contact an authorized dealer as
soon as possible.
WINDSHIELD WIPER
Periodically clean the windshield and rear window
and rubber profile of the windshield wiper blades,
using a sponge or a soft cloth and a non-abrasive
detergent. This eliminates the salt or impurities
accumulated when driving.
Prolonged operation of the windshield window
wipers with dry glass may cause the deterioration
of the blades, in addition to abrasion of the
surface of the glass. To eliminate the impurities
on the dry glass, always operate the windshield
washers. In the event of very low outdoor temperatures,
below 0°F (-17.8°C), ensure that the movement
of the rubber part in contact with the glass is not
obstructed. Use a suitable deicing product to
release it if required.
Avoid using the windshield wipers to remove frost
or ice.
Also avoid contact of the rubber profile of the
blades with petroleum derivatives such as engine
oil, gas, etc.

NOTE:
The life of the windshield wiper blades varies
according to the usage frequency. In any case, it
is advised to replace the blades approximately
once a year. When the blades are worn, noise,
marks on the glass or streaks of water may be
noticed. In the presence of these conditions,
clean the windshield wiper blades or, if neces
-
sary, replace them.
Raising The Windshield Wiper Blades (“Service
Position” Function)
The “service position” function allows the driver
to replace the windshield wiper blades more
easily. It is also recommended to activate this
function when it is snowing and to make it easier
to remove any dirt deposits in the area where the
blades are normally positioned, when washing. Activation Of The Function
To activate this function, disable the windshield
wiper before setting the ignition device to OFF.
This function can only be activated within two
minutes of placing the ignition in OFF.
To activate this function, move the lever upward
for at least three seconds.
Windshield Wiper Stalk
Function Deactivation
The function is deactivated if:
More than two minutes passes before placing
the ignition in the STOP position after having
raised the lever and putting the wipers into
service position.
The ignition is placed in the ACC position and
the windshield wiper control is used.
If, after using the function, the ignition is set back
to ACC with the blades in a position other than
rest position (at the base of the windshield), 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.
WARNING!
Driving with worn windshield wiper blades is a
serious hazard, because visibility is reduced in
bad weather conditions.

Replacing The Windshield Wiper Blades
Proceed as follows:
1. Raise the wiper arm, press tab of the attach -
ment spring and remove the blade from the
arm.
Wiper Release Tab
2. Fit the new blade, inserting the tab in the dedicated housing in the arm and checking
that it is locked.
3. Lower the wiper arm onto the windshield.

NOTE:
Do not operate the windshield wiper with the
blades lifted from the windshield.
Windshield Washer
The window washer nozzles are fixed. If there is
no jet of fluid, first check that there is fluid in the
reservoir. Windshield Washers
Then, check that the nozzle holes are not
clogged; use a needle to unblock them if
necessary.
EXHAUST SYSTEM
Adequate maintenance of the engine exhaust
system represents the best protection against
leaks of carbon monoxide into the passenger
compartment.
If an unusual noise from the exhaust or the
presence of smoke in the passenger
compartment is identified, or if the underbody or
rear section of the vehicle have been damaged,
have the entire exhaust system and adjoining
bodywork areas checked at an authorized dealer
to identify any components which are broken,
damaged, worn or have moved from their correct
fitting position. Open welding or loose connections may permit
exhaust gas to enter the passenger
compartment.
Have the exhaust system checked every time the
vehicle is raised. Replace the components where
necessary (for these operations, contact an
authorized dealer).
In normal operating conditions, the catalytic
converter does not require maintenance. To
ensure that it operates correctly, however, and
prevent it from getting damaged, it is extremely
important that the engine operates perfectly.
To minimize the risk of damaging the catalytic
converter, proceed as follows:
Do not stop the engine or deactivate the
ignition with gear engaged and vehicle in
motion.
Do not attempt to start the engine by bump
starting.
Do not persist in using the vehicle if idling is
very irregular or the operating conditions are
very notably irregular.
1 — Washer Nozzles
WARNING!
Exhaust gases can injure or kill. They contain
carbon monoxide (CO), which is colorless and
odorless. Breathing it can make you
unconscious and can eventually poison you.
A hot exhaust system can start a fire if you
park over materials that can burn. Such
materials might be grass or leaves coming
into contact with your exhaust system. Do not
park or operate your vehicle in areas where
your exhaust system can contact anything
that can burn.
