USEFUL ADVICE FOR EXTENDING THE LIFE
O
F YOUR BATTERY
To avoid draining your battery and make it last
longer, observe the following instructions:
When you park the vehicle, ensure that the
doors and liftgate 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 vehicle that require permanent
electrical supply (e.g. alarm, etc.), or accessories
which influence the electrical supply
requirements, contact an authorized dealer,
who’s qualified staff will evaluate the overall
electrical consumption.

NOTE:
After the battery is disconnected, the steering
must be initialized. The Power Steering
Warning Light on the instrument cluster display
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.
CAUTION!
If the charge level remains under 50% for a
long time, the battery may be damaged by
sulfation, reducing its capacity and efficiency
during the 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. If acid splashes in eyes or on skin,
flush the area immediately with large
amounts of water

Ú
page 192.
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.

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
category is shown on the sidewall of
the tires on your vehicle.

All passenger vehicle tires must conform
to Federal safety requirements 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
performance 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
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 (EPB) is
not activated.
Carry out the “Liftgate Emergency Opening”
procedure
Ú
page 62.
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.
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.

Dry the less visible parts (e.g. door frames, hood,
headlight frames, etc.) with special care, as water
may stagnate more easily in these areas. Do not
wash the vehicle after it has been left in the sun
or with the hood hot: this may alter the shine of
the paintwork.

NOTE:
Avoid parking under trees; the resin dropped by
trees makes the paintwork go opaque and
increases the possibility of corrosion.
Exterior plastic parts must be cleaned in the
same way as the rest of the vehicle.
If washing the vehicle in a service that moves the
vehicle, for vehicles with automatic
transmissions, proceed with the following
directions:
Ensure that the vehicle is on a flat surface.
Disable the automatic engagement of the
parking brake
Ú
page 89.
With the vehicle stationary, the gear in
NEUTRAL (N) and the brake pedal pressed,
push the START button.

NOTE:
The vehicle will remain in NEUTRAL (N) for
15 minutes before PARK (P) will be engaged
automatically.Windows
Use specific detergents and clean cloths to
prevent scratching or altering the transparency.
Front Headlights
Use a soft cloth soaked in water and detergent for
washing vehicles.

NOTE:

Never use aromatic substances (e.g. gasoline)
or ketones (e.g. acetone) for cleaning the
plastic lenses of the headlights.
When cleaning with a pressure washer, keep
the pressure washer at least eight inches
(20 cm) away from the headlights.
Engine Compartment
At the end of every Winter, wash the engine
compartment thoroughly, taking care not to aim
the jet of water directly at the electronic control
units or at the windshield wiper motors. Have this
operation performed at a specialized workshop

Ú
page 208.

NOTE:
The washing should take place with the engine
cold and the ignition device in the STOP position.
After the washing operation, make sure that the
various protections (e.g. rubber caps and guards)
have not been removed or damaged.
INTERIORS
Periodically check the cleanliness of the interior,
beneath the mats, which could cause oxidation of
the sheet metal.
SEATS AND FABRIC PARTS
Remove dust with a soft brush or a vacuum
cleaner. It is advised to use a moist brush on
velvet upholstery. Rub the seats with a sponge
moistened with a solution of water and neutral
detergent.
Cleaning heat press images on seats —
if equipped:
Due to the color, opacity and wear-resistant
protection with which the heat press images on
some seats are made, they may be subject to
temporary scratching if they are touched by finger
nails, keys, or other hard objects. In such cases,
the visible signs do not impair the profiled
images, and can easily be removed by wiping the
affected area with a microfiber cloth moistened
with water (not dry) to restore the seat to its
original condition. The microfiber cloth must not
have been previously soaked in other substances
or detergents.
CAUTION!
Wipe the rear window inside gently with a
cloth following the direction of the filaments to
avoid damaging the heating device.
