Alfa Romeo 4C Spider (2018 year). Manual - part 59

 

 

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 con-
trolled conditions on specified government test sur-
faces of asphalt and concrete. A tire marked C may
have poor traction performance.
WARNING!
The traction grade assigned to this tire is based
on straight-ahead braking traction tests, and does
not include acceleration, cornering, hydroplan-
ing, or peak traction characteristics.
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 perfor-
mance on the laboratory test wheel, than the mini-
mum required by law.

SERVICING AND MAINTENANCE
WARNING!
The temperature grade for this tire is established
for a tire that is properly inflated and not over-
loaded. Excessive speed, under-inflation, or ex-
cessive loading, either separately or in combina-
tion, can cause heat buildup and possible tire
failure.
VEHICLE STORAGE
If you are leaving your vehicle dormant for more than
21 days, you may want to take these steps to protect
your battery.
Disconnect the negative cable from the battery.
Anytime you store your vehicle, or keep it out of
service (e.g., vacation) for two weeks or more, run the
air conditioning system at idle for about five minutes
in the fresh air and high blower setting. This will
ensure adequate system lubrication to minimize the
possibility of compressor damage when the system is
started again.
BODYWORK
Protection From Atmospheric Agents
Vehicle body care requirements vary according to geo-
graphic locations and usage. Chemicals that make roads
passable in snow and ice and those that are sprayed on
trees and road surfaces during other seasons are highly
corrosive to the metal in your vehicle. Outside parking,
which exposes your vehicle to airborne contaminants,
road surfaces on which the vehicle is operated, extreme
hot or cold weather and other extreme conditions will
have an adverse effect on paint, metal trim, and under-
body protection.
The following maintenance recommendations will en-
able you to obtain maximum benefit from the corrosion
resistance built into your vehicle.

What Causes Corrosion?
Corrosion is the result of deterioration or removal of
paint and protective coatings from your vehicle.
The most common causes are:
Road salt, dirt and moisture accumulation.
Stone and gravel impact.
Insects, tree sap and tar.
Salt in the air near seacoast localities.
Atmospheric fallout/industrial pollutants.
Body And Underbody Maintenance
Cleaning Headlights
Your vehicle is equipped with plastic headlights and
fog lights that are lighter and less susceptible to stone
breakage than glass headlights.
Plastic is not as scratch resistant as glass and therefore
different lens cleaning procedures must be followed.
To minimize the possibility of scratching the lenses and
reducing light output, avoid wiping with a dry cloth. To
remove road dirt, wash with a mild soap solution
followed by rinsing.
Do not use abrasive cleaning components, solvents,
steel wool or other aggressive material to clean the
lenses.
Preserving The Bodywork
Washing
Wash your vehicle regularly. Always wash your
vehicle in the shade using Mopar Car Wash, or a mild
car wash soap, and rinse the panels completely with
clear water.
If insects, tar, or other similar deposits have accumu-
lated on your vehicle, use Mopar Super Kleen Bug
and Tar Remover to remove.
Use a high quality cleaner wax, such as Mopar
Cleaner Wax to remove road film, stains, and to
protect your paint finish. Take care never to scratch
the paint.
Avoid using abrasive compounds and power buffing
that may diminish the gloss or thin out the paint
finish.
NOTE:
Hand washing is recommended. Avoid washing
with power washers and do not use commercial car
wash facilities.

SERVICING AND MAINTENANCE
CAUTION!
Do not use abrasive or strong cleaning materials
such as steel wool or scouring powder that will
scratch metal and painted surfaces.
Use
of
power
washers
exceeding
1,200
psi
(8 274 kPa) can result in damage or removal of
paint and decals.
If the engine compartment is washed with an
high pressure jet, keep it at a distance of at least 8
inches (20 centimeters) from filler surface.
Do not run this vehicle through an Automatic Car
Wash facility as extensive damage can result due
to the vehicle’s low ground clearance.
Special Care
If you drive on salted or dusty roads or if you drive
near the ocean, hose off the undercarriage at least
once a month.
It is important that the drain holes in the lower edges
of the doors, rocker panels, and trunk be kept clear
and open.
If you detect any stone chips or scratches in the paint,
touch them up immediately. The cost of such repairs
is considered the responsibility of the owner.
If your vehicle is damaged due to a collision or
similar cause that destroys the paint and protective
coating, have your vehicle repaired as soon as pos-
sible. The cost of such repairs is considered the
responsibility of the owner.
If you carry special cargo such as chemicals, fertiliz-
ers, de-icer salt, etc., be sure that such materials are
well packaged and sealed.
If a lot of driving is done on gravel roads, consider
mud or stone shields behind each wheel.
Use Mopar Touch Up Paint on scratches as soon as
possible. Your authorized dealer has touch up paint
to match the color of your vehicle.
