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:
Check cleanliness of hood and trunk locks,
cleanliness and lubrication of linkage.
Visually inspect conditions of: engine,
transmission, pipes and hoses (exhaust/fuel
system/brakes) and rubber elements
(sleeves/bushes, etc.).
Check battery charge and battery fluid level
(electrolyte).
Visually inspect conditions of the accessory
drive belts.
Check and, if necessary, change engine oil and
replace oil filter.
Check and, if necessary, replace cabin air
filter.
Check and, if necessary, replace engine air
cleaner.
Severe Duty All Models
Vehicles that are operated in a dusty and off-road
environment, or predominately at idle or very low
engine RPM are known as Severe Duty vehicles.
It is recommended that you change engine oil at
4,000 miles (6,500 km) or 350 hours of engine
run time.

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.

actual conditions of their use, however,
and may depart significantly from the
norm due to variations in driving habits,
service practices, and differences in
road characteristics and climate.
TRACTION GRADES
The Traction grades, from highest to
lowest, are AA, A, B, and C. These
grades represent the tire's ability to
stop on wet pavement, as measured
under controlled conditions on
specified government test surfaces of
asphalt and concrete. A tire marked C
may have poor traction performance.
TEMPERATURE GRADES
The temperature grades are A (the
highest), B, and C, representing the
tire's resistance to the generation of
heat and its ability to dissipate heat,
when tested under controlled
conditions on a specified indoor
laboratory test wheel. Sustained high
temperature can cause the material of
the tire to degenerate and reduce tire life, and excessive temperature can
lead to sudden tire failure. The grade C
corresponds to a level of performance,
which all passenger vehicle tires must
meet under the Federal Motor Vehicle
Safety Standard No. 109. Grades B and
A represent higher levels of
performance on the laboratory test
wheel, than the minimum required by
law.
STORING THE VEHICLE
If the vehicle is left inactive for longer than a
month, the following precautions should be
observed:
Park the vehicle in an area that is covered and
dry, and well-ventilated if possible. Slightly
open the windows.
Check that the Electric Park Brake is not
activated.
Carry out the procedure: “manual trunk
opening device” procedure described in this
paragraph.
Disconnect the negative battery terminal and
check the battery charge. Repeat this check
once every three months during storage.
If the battery is not disconnected from the
electrical system, check its state of charge
every 30 days.
Clean and protect the painted parts using
protective wax.
Clean and protect the shiny metal parts using
special compounds available commercially.

Sprinkle talcum powder on the windshield wiper
rubber blades, and lift them off the glass.

Cover the vehicle with a fabric or perforated
plastic sheet, paying particular care not to
damage the painted surface by dragging any
dust that may have accumulated on it. Do not
use compact plastic sheets, as they do not
allow humidity to evaporate from the surface
of the vehicle.
Inflate tires to +7.25 psi (+0.5 bar) above the
standard prescribed pressure and check it
periodically.
Do not drain the engine cooling system.

Any time the vehicle is left inactive for two
weeks or more, operate the air conditioning
system with engine idling for at least five
minutes, setting external air and with fan set to
maximum speed. This operation will ensure
appropriate lubrication for the system, thus
minimizing the possibility of damage to the
compressor when the system is operated again.
NOTE:
After placing the ignition in STOP and having
closed the driver side door, wait at least one
minute before disconnecting the electrical supply
from the battery. When reconnecting the elec
-
trical supply to the battery, make sure that the
ignition is in the STOP position and the driver side
door is closed.
WARNING!
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration,
cornering, hydroplaning, or peak traction
characteristics.
WARNING!
The temperature grade for this tire is
established for a tire that is properly inflated
and not overloaded. Excessive speed,
underinflation, or excessive loading, either
separately or in combination, can cause heat
buildup and possible tire failure.
