Tire Rotation Recommendations
Tires on the front and rear axles of vehicles
operate at different loads and perform
different steering, driving, and braking func-
tions. For these reasons, they wear at unequal
rates. These effects can be reduced by timely
rotation of tires. Rotation will increase tread
life, maintain traction levels and contribute to
a smooth, quiet ride.
To resolve this problem, tires should be
rotated at each service interval (approximately
every 10,000 miles [16,000km]). More
frequent rotation is permissible if desired. The
reasons for any rapid or unusual wear should
be corrected prior to rotation being performed.
Tire Rotations Not Recommended — If
Equipped
Due to different size tires and wheels on front
and rear axles tire rotation is not possible for:
2.0T GME Engine Equipped with a 225/
40R19 front and 255/35R19 rear tires
2.9L V6 Engine Equipped with 19” tires and
wheels
Tire rotation contributes to the preservation of
the grip and traction performance on wet,
muddy or snowy roads, guaranteeing optimal
driveability of the vehicle.
In the case of irregular wear of the tires iden -
tify the cause and correct it as soon as
possible, by contacting an authorized dealer.
Tire Rotation for Directional Tires — If
Equipped
Directional tires are equipped on the following:
2.0T GME Engine equipped with same size
tires and wheels on front and rear axles
The rotational direction of the tire must be
taken into consideration when rotating the
tires. The recommended rotation pattern for
directional tires is shown below. Tire Rotation
All Wheel Drive (AWD) Models
It is recommended to avoid situations with a
large difference in wear between the front and
rear tires and to strictly use Winter tires of the
sizes given on the tire placard.
The AWD system and the original tires are
developed together to ensure the vehicle’s
best performance. When changing the tires, it
is recommended to us the same “AR” marked
tires, to maintain the same level of perfor -
mance and component life.
CAUTION!
Damage to the vehicle may occur if 225/
40R19 front and 255/35R19 rear tires are
rotated
CAUTION!
Damage to the vehicle may occur if 19”
front and rear tires are rotated

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.

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 car after it has been
left in the sun or with the hood hot: this may
alter the shine of the paintwork.
Exterior plastic parts must be cleaned in the
same way as the rest of the vehicle.
If washing the car in a service that moves the
car, for cars with automatic transmissions,
PARK (P) must be cut out. You have to shut off
the engine in the following conditions: car
stopped, transmission in NEUTRAL (N), push
the starter button for at least three seconds.

NOTE:

Avoid parking under trees; the resin dropped
by trees makes the paintwork go opaque and
increases the possibility of corrosion.
Windows
Use specific detergents and clean cloths to
prevent scratching or altering the transpar -
ency. Front Headlights

Use a soft cloth soaked in water and detergent
for washing cars.

NOTE:

Never use aromatic substances (e.g. gaso -
line) 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. For further information

Ú
page 215.

NOTE:

The washing should take place with the engine
cold and the ignition device in the STOP posi -
tion. 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 inte -
rior, 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. Rub the seats with a sponge moist -
ened 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 micro -
fiber 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.

CAUTION!
Water, ice and salt spread on the roads may deposit on the brake discs, reducing braking efficiency the first time the brakes are applied.
To obtain the maximum efficiency of the braking system, a bedding-in period of about 300 miles (500 km) is needed: during this period it is
better to avoid sharp, repeated and prolonged braking.
