NOTE:
If you intend parking or storing your vehicle for an
extended period after cleaning the wheels with
wheel cleaner, drive your vehicle and apply the
brakes to remove the water droplets from the
brake components. This activity will remove the
red rust on the brake rotors and prevent vehicle
vibration when braking.
Dark Or Low Gloss Wheels
TIRE TYPES
All Season Tires — If Equipped
All Season tires provide traction for all seasons
(Spring, Summer, Autumn, and Winter). Traction
levels may vary between different all season
tires. All season tires can be identified by the
M+S, M&S, M/S or MS designation on the
tire sidewall. Use all season tires only in sets of
four; failure to do so may adversely affect the
safety and handling of your vehicle.
Summer Or Three Season Tires —
If Equipped
Summer tires provide traction in both wet and dry
conditions, and are not intended to be driven in
snow or on ice. If your vehicle is equipped with
Summer tires, be aware these tires are not
designed for Winter or cold driving conditions.
Install Winter tires on your vehicle when ambient
temperatures are less than 40°F (5°C) or if
roads are covered with ice or snow. For more
information, contact an authorized dealer.
Summer tires do not contain the all season
designation or mountain/snowflake symbol on
the tire sidewall. Use Summer tires only in sets of
four; failure to do so may adversely affect the
safety and handling of your vehicle.
Snow Tires
Some areas of the country require the use of
snow tires during the Winter. Snow tires can be
identified by a “mountain/snowflake” symbol on
the tire sidewall.If you need snow tires, select tires
equivalent in size and type to the
original equipment tires. Use snow tires
only in sets of four; failure to do so may
adversely affect the safety and handling of your
vehicle. Snow tires generally have lower speed ratings
than what was originally equipped with your
vehicle and should not be operated at sustained
speeds over 75 mph (120 km/h). For speeds
above 75 mph (120 km/h) refer to original
equipment or an authorized tire dealer for
recommended safe operating speeds, loading
and cold tire inflation pressures.
While studded tires improve performance on ice,
skid and traction capability on wet or dry surfaces
may be poorer than that of non-studded tires.
Some states prohibit studded tires; therefore,
local laws should be checked before using these
tire types.
TIRE CHAINS AND TRACTION DEVICES
It is possible to fit 13 mm chains on the tires:
2.0L engines, 18” and 19” are chainable.
2.9L engines, 20” and 21” are chainable.
Use of traction devices require sufficient
tire-to-body clearance. Follow these recommen -
dations to guard against damage.

NOTE:

Traction device must be of proper size for the
tire, as recommended by the traction device
manufacturer.
Use on rear tires only.
Check the tension of the snow chains after the
first few meters have been driven.
Using snow chains with tires with non-original
dimensions may damage the vehicle.
Using different tires sizes or types (M+S, snow,
etc.) between the front and rear axles may
adversely affect vehicle drivability, with the
risk of losing control of the vehicle and
resulting accidents.
CAUTION!
If your vehicle is equipped with these specialty
wheels, DO NOT USE wheel cleaners,
abrasives, or polishing compounds. They will
permanently damage this finish and such
damage is not covered by the New Vehicle
Limited Warranty. HAND WASH ONLY USING
MILD SOAP AND WATER WITH A SOFT CLOTH.
Used on a regular basis; this is all that is
required to maintain this finish.
WARNING!
Do not use Summer tires in snow/ice
conditions. You could lose vehicle control,
resulting in severe injury or death. Driving too
fast for conditions also creates the possibility
of loss of vehicle control.

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 cycling the ignition to 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’s
side door is closed.
BODYWORK
PROTECTION AGAINST ATMOSPHERIC
A
GENTS
The vehicle is equipped with the best available
technological solutions to protect the bodywork
against corrosion.
These include:
Painting products and systems which give the
vehicle resistance to corrosion and abrasion.
Use of galvanized (or pre-treated) steel sheets,
with high resistance to corrosion.
Spraying of plastic parts, with a protective
function in the more exposed points: under
door, inner wing, edges, etc.
Use of “open” boxed sections to prevent
condensation and pockets of moisture which
could favor the formation of rust inside.
Use of special films to protect against abrasion
in exposed areas (e.g. rear wing, doors, etc.).
CORROSION WARRANTY
Your vehicle is covered by Corrosion Warranty
against perforation due to rust of any original
element of the structure or bodywork. For the
general terms of this warranty, refer to the
Warranty Booklet.
PRESERVING THE BODYWORK
Paint
Touch up abrasions and scratches immediately to
prevent the formation of rust.
Maintenance of paintwork consists of washing
the vehicle: the frequency depends on the
conditions and environment where the vehicle is
used. For example, it is advisable to wash the
vehicle more often in areas with high levels of
atmospheric pollution or salted roads.
Some parts of the vehicle may be covered with a
matte paint which, in order to be maintained
intact, requires special care.
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)

Ú
page 209.
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.
23_GU_OM_EN_USC_t.book Page 239

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.
