FUSES
General Information
The fuses protect electrical systems against
excessive current.
When a device does not work, you must check the
electrical circuit inside of the fuse for a break/
melt.
Also, please be aware that using power outlets for
extended periods of time with the engine off may
result in vehicle battery discharge.
Blade Fuses
To avoid contamination from foreign matter
or moisture, use only new brake fluid or fluid
that has been in a tightly closed container.
Keep the master cylinder reservoir cap
secured at all times. Brake fluid in an open
container absorbs moisture from the air
resulting in a lower boiling point. This may
cause it to boil unexpectedly during hard or
prolonged braking, resulting in sudden brake
failure. This could result in a collision.
Overfilling the brake fluid reservoir can result
in spilling brake fluid on hot engine parts,
causing the brake fluid to catch fire. Brake
fluid can also damage painted and vinyl
surfaces, care should be taken to avoid its
contact with these surfaces.
Do not allow petroleum-based fluid to
contaminate the brake fluid. Brake seal
components could be damaged, causing
partial or complete brake failure. This could
result in a collision.
WARNING! CAUTION!

Do not use chemical flushes in your
transmission as the chemicals can damage your
transmission components. Such damage is not
covered by the New Vehicle Limited Warranty.

CAUTION!
If a transmission fluid leak occurs, visit an
authorized dealer immediately. Severe
transmission damage may occur. An
authorized dealer has the proper tools to
adjust the fluid level accurately.

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.
23_GU_OM_EN_USC_t.book Page 238

239

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.
