Alfa Romeo 4C 2018 Owner's Manual

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.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.

SERVICING AND MAINTENANCE 239

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.
240 SERVICING AND MAINTENANCE

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.
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.

SERVICING AND MAINTENANCE 241

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.
INTERIORS
Seats And Fabric Parts
Use Mopar Total Clean to clean fabric upholstery and
carpeting.
WARNING!
Do not use volatile solvents for cleaning purposes.
Many are potentially flammable, and if used in
closed areas they may cause respiratory harm.
Seat Belt Maintenance
Do not bleach, dye, or clean the belts with chemical
solvents or abrasive cleaners. This will weaken the
fabric. Sun damage can also weaken the fabric.
If the belts need cleaning, use Mopar Total Clean, a mild
soap solution, or lukewarm water. Do not remove the
belts from the vehicle to wash them. Dry with a soft
cloth.
Replace the belts if they appear frayed or worn or if the
buckles do not work properly.
242 SERVICING AND MAINTENANCE

NOTE:If the belts retract slowly, inspect the upper
turning loop for soiling. If soiling is present, clean with
a wet soft cloth until all residue is removed.
WARNING!
A frayed or torn belt could rip apart in a collision
and leave you with no protection. Inspect the belt
system periodically, checking for cuts, frays, or
loose parts. Damaged parts must be replaced imme-
diately. Do not disassemble or modify the system.
Seat belt assemblies must be replaced after a colli-
sion if they have been damaged (i.e., bent retractor,
torn webbing, etc.).
Plastic And Coated Parts
Use Mopar Total Clean to clean vinyl upholstery.
CAUTION!
•Direct contact of air fresheners, insect repellents,
suntan lotions, or hand sanitizers to the plastic,
painted, or decorated surfaces of the interior may
cause permanent damage. Wipe away immediately.

CAUTION! (Continued)
•Damage caused by these type of products may not
be covered by your New Vehicle Limited War-
ranty.
Cleaning Plastic Instrument Cluster Lenses
The lenses in front of the instruments in this vehicle are
molded in clear plastic. When cleaning the lenses, care
must be taken to avoid scratching the plastic.
1. Clean with a wet soft cloth. A mild soap solution may be used, but do not use high alcohol content or
abrasive cleaners. If soap is used, wipe clean with a
clean damp cloth.
2. Dry with a soft cloth.
Leather Parts
Mopar Total Clean is specifically recommended for
leather upholstery.
Your leather upholstery can be best preserved by regu-
lar cleaning with a damp soft cloth. Small particles of
dirt can act as an abrasive and damage the leather
upholstery and should be removed promptly with a
damp cloth. Stubborn soils can be removed easily with

a soft cloth and Mopar Total Clean. Care should be
taken to avoid soaking your leather upholstery with
any liquid. Please do not use polishes, oils, cleaning
fluids, solvents, detergents, or ammonia-based cleaners
to clean your leather upholstery. Application of a
leather conditioner is not required to maintain the
original condition.
NOTE:If equipped with light colored leather, it tends to
show any foreign material, dirt, and fabric dye transfer
more so than darker colors. The leather is designed for
easy cleaning, and FCA recommends Mopar total care
leather cleaner applied on a cloth to clean the leather
seats as needed.
CAUTION!
Do not use Alcohol and Alcohol-based and/or Ke-
tone based cleaning products to clean leather seats,
as damage to the seat may result.
Glass Surfaces
All glass surfaces should be cleaned on a regular basis
with Mopar, or any commercial household-type glass
cleaner. Never use an abrasive type cleaner. Use caution
when cleaning the inside rear window equipped. Do
not use scrapers or other sharp instrument that may
scratch the elements.
Labels can be peeled off after soaking with warm water
(if equipped), keep all objects a safe distance from the
windows.
When cleaning the rear view mirror, spray cleaner on
the towel or cloth that you are using. Do not spray
cleaner directly on the mirror.

VEHICLE IDENTIFICATION NUMBER
The Vehicle Identification Number (VIN) is found on
the left front corner of the instrument panel, visible
through the windshield. This number also appears
engraved on an Aluminum plate glued and riveted on
the floor crossmember under the passenger seat.
NOTE:It is illegal to remove or alter the VIN.
WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to ensure
that the wheel is properly mounted to the vehicle. Any
time a wheel has been removed and reinstalled on the
vehicle, the lug nuts/bolts should be torqued using a
properly calibrated torque wrench using a high quality
six sided (hex) deep wall socket.

Inspect the wheel mounting surface prior to mounting
the tire and remove any corrosion or loose particles.
Tighten the lug nuts/bolts in a star pattern until each
nut/bolt has been tightened twice. Ensure that the
socket is fully engaged on the lug nut/bolt (do not
insert it halfway).After 25 miles (40 km) check the lug nut/bolt torque to
be sure that all the lug nuts/bolts are properly seated
against the wheel.
WARNING!
To avoid the risk of forcing the vehicle off the jack,
do not tighten the lug nuts fully until the vehicle
has been lowered. Failure to follow this warning
may result in personal injury.

BRAKE SYSTEM
Your vehicle is equipped with dual hydraulic brake
systems. If either of the two hydraulic systems loses
normal capability, the remaining system will still func-
tion. However, there will be some loss of overall brak-
ing effectiveness. You may notice increased pedal travel
during application, greater pedal force required to slow
or stop, and potential activation of the “Brake System
Warning Light”.
In the event power assist is lost for any reason (i.e.,
repeated brake applications with the engine off), the
brakes will still function. However, the effort required
to brake the vehicle will be much greater than that
required with the power system operating.
FUEL REQUIREMENTS — 1750 TURBO
The 1750 turbo engine is designed to
meet all emissions regulations and pro-
vide excellent fuel economy and perfor-
mance when using high-quality premium
unleaded gasoline with an octane rating
of only 91 or higher. Light spark knock at low engine speeds is not harmful
to your engine. However, continued heavy spark knock
at high speeds can cause damage and immediate ser-
vice is required.
Poor quality gasoline can cause problems such as hard
starting, stalling and hesitations. If you experience these
symptoms, try another brand of gasoline (with the
appropriate octane rating for your engine) before con-
sidering service for the vehicle.
Reformulated Gasoline
Many areas of the country require the use of cleaner
burning gasoline referred to as “Reformulated Gaso-
line”. Reformulated gasoline contains oxygenates and
are specifically blended to reduce vehicle emissions and
improve air quality.
The use of reformulated gasoline is recommended.
Properly blended reformulated gasoline will provide
improved performance and durability of engine and
fuel system components.
Materials Added To Fuel
Besides using unleaded gasoline with the proper octane
rating, gasolines that contain detergents, corrosion and
stability additives are recommended. Using gasolines
