Tire Pressures For High Speed Operation
The manufacturer advocates driving at safe
speeds and within posted speed limits. Where
speed limits or conditions are such that the
vehicle can be driven at high speeds, maintaining
correct tire inflation pressure is very important.
Increased tire pressure and reduced vehicle
loading may be required for high-speed vehicle
operation. Refer to an authorized tire dealer or
original equipment vehicle dealer for
recommended safe operating speeds, loading
and cold tire inflation pressures.Recommended Cold Tire Inflation Pressures
For vehicle speeds below 100 mph (160 km/h),
recommended cold tire inflation pressures are
listed on the Tire And Loading Information
Placard located on driver’s side B-pillar or the rear
edge of the driver's side door. When driving at speeds 100 mph (160 km/h)
and above, increased tire pressures and reduced
vehicle loading are required for high-speed
vehicle operation.
For driving speeds above 100 mph (160 km/h)
recommended cold tire inflation pressures are
listed in the following table under "High Speed
Tire Inflation Pressure". Vehicle loading condition
must not exceed 688 lb. (312kg) (driver + three
passengers + 88 lb. (40kg) luggage).

WARNING!

High speed driving with your vehicle under max -
imum load is dangerous. The added strain on
your tires could cause them to fail. You could
have a serious collision. Do not drive a vehicle
loaded to the maximum capacity at continuous
speeds above 75 mph (120 km/h).

Radial Ply Tires
Tire Repair
If your tire becomes damaged, it may be repaired
if it meets the following criteria:
The tire has not been driven on when flat.
The damage is only on the tread section of your
tire (sidewall damage is not repairable).
The puncture is no greater than a ¼ of an inch
(6 mm).
Consult an authorized tire dealer for tire repairs
and additional information. Damaged Run Flat tires, or Run Flat tires that
have experienced a loss of pressure should be
replaced immediately with another Run Flat tire
of identical size and service description (Load
Index and Speed Symbol). Replace the tire
pressure sensor as well as it is not designed to be
reused.
Run Flat Tires — If Equipped
Run Flat tires allow you the capability to drive
50 miles (80 km) at 50 mph (80 km/h) after a
rapid loss of inflation pressure. This rapid loss of
inflation is referred to as the Run Flat mode. A
Run Flat mode occurs when the tire inflation
pressure is of/or below 14 psi (96 kPa). Once a
Run Flat tire reaches the Run Flat mode it has
limited driving capabilities and needs to be
replaced immediately. A Run Flat tire is not
repairable. When a Run Flat tire is changed after
being driven under a Run Flat mode 14 psi
(96 kPa) condition, please replace the TPMS
sensor as it is not designed to be reused.

NOTE:
The TPMS sensor must be replaced after driving
the vehicle on a flat tire condition. It is not recommended driving a vehicle loaded at
full capacity or to tow a trailer while a tire is in the
Run Flat mode.

Tire Spinning
When stuck in mud, sand, snow, or ice conditions,
do not spin your vehicle's wheels above 30 mph
(48 km/h) or for longer than 30 seconds contin

WARNING!
Combining radial ply tires with other types of
tires on your vehicle will cause your vehicle to
handle poorly. The instability could cause a
collision. Always use radial ply tires in sets of
four. Never combine them with other types of
tires.
WARNING!

Fast spinning tires can be dangerous. Forces
generated by excessive wheel speeds may
cause tire damage or failure. A tire could
explode and injure someone. Do not spin your
vehicle's wheels faster than 30 mph (48 km/h)
for more than 30 seconds continuously when
you are stuck, and do not let anyone near a
spinning wheel, no matter what the speed.

TIRE ROTATION RECOMMENDATIONS
Tires on the front and rear axles of vehicles
operate at different loads and perform different
steering, driving, and braking functions. 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
wheelsTire rotation contributes to the preservation of the
grip and traction performance on wet, muddy or
snowy roads, guaranteeing optimal drivability of
the vehicle.
In the case of irregular wear of the tires identify
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 in the following diagram.
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 performance and
component life.

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 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.

To correctly wash the vehicle, follow these
instructions:
If high pressure jets or cleaners are used to
wash the vehicle, keep a distance of at least
15 inches (40 cm) from the bodywork to avoid
damage or alteration. Build up of water could
cause damage to the vehicle in the long term.
To make it easier to remove any dirt deposits
in the area where the blades are normally
located it is recommended to position the
windshield wipers vertically (service position).
Wash the bodywork using a low pressure jet of
water if possible.
Wipe a sponge with a slightly soapy solution
over the bodywork, frequently rinsing the
sponge.
Rinse well with water and dry with a leather
chamois.
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 transparency.
Front Headlights
Use a soft cloth soaked in water and detergent for
washing cars.

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.
For further information

page 191.

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. 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.

LEATHER SEATS
Remove the dry dirt with a chamois or slightly
damp cloth, without exerting too much pressure.
Remove any liquid or grease stains using an
absorbent dry cloth, without rubbing. Then clean
with a soft cloth or buckskin cloth dampened with
water and mild soap. If the stain persists, use
specific products and observe the instructions
carefully.

NOTE:
Never use alcohol. Make sure that the cleaning
products used contain no alcohol or alcohol deriv -
atives, even in small quantities.
CAUTION!
Wipe the rear window inside gently with a cloth
following the direction of the filaments to avoid
damaging the heating device.
