If the level is too low, remove the cap of reser-
voir and add the fluid described on

Ú
page 267.
Washer Fluid For Windshield/Headlights
The windshield and headlights washer fluid
reservoir has a telescopic filler.
If the level is too low, remove reservoir cap and
lift the filler. Then, add the fluid described on

Ú
page 267.

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 reference 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 System Oil

The transmission control oil level should only
be checked at an authorized dealer.
Useful Advice For Extending The Life 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 perma -
nent 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.
WARNING!
If the engine oil is being topped up, wait for
the engine to cool down before loosening
the filler cap, particularly for vehicles with
aluminum cap (if equipped). WARNING: risk
of burns!
CAUTION!
The oil level must never exceed the MAX
mark.
If the MAX mark is exceeded (last notch on
the right turns red) after the fill-up, go to an
authorized dealer as soon as possible to
have the oil in excess removed.
Do not add oil with specifications different
from those of the oil already in the engine.
Used engine oil and oil filters contain
substances which are harmful to the
environment. To change the oil and filters,
we advise you to contact an authorized
dealer.
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).

DEPARTMENT OF
TRANSPORTATION UNIFORM
TIRE QUALITY GRADES
The following tire grading categories
were established by the National
Highway Traffic Safety Administration.
The specific grade rating assigned by
the tire's manufacturer in each cate-
gory is shown on the sidewall of the
tires on your vehicle.
All passenger vehicle tires must
conform to Federal safety require -
ments in addition to these grades.
Treadwear
The Treadwear grade is a comparative
rating, based on the wear rate of the
tire when tested under controlled
conditions on a specified government
test course. For example, a tire graded
150 would wear one and one-half times
as well on the government course as a
tire graded 100. The relative perfor -
mance of tires depends upon the
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 speci -
fied 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 condi -
tions 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 corre -
sponds 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.
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,
under-inflation, or excessive loading, either
separately or in combination, can cause
heat buildup and possible tire failure.

21_GA_OM_EN_USC_t.book Page 250

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 electrical supply to the battery, make sure
that the ignition is in the STOP position and the
driver side door is closed. Manual Trunk Opening Device
Proceed as follows if the battery needs to be
disconnected:
1. From the trunk interior covering, rotate the
plug counterclockwise of the lock and
extract the cord connected to it.
