Alfa Romeo 4C Spider (2018 year). Manual - part 61

 

 

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.

TECHNICAL SPECIFICATIONS
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
that
have
these
additives
will
help
improve
fuel
economy, reduce emissions, and maintain vehicle per-
formance.
Designated
TOP
TIER
Detergent
Gasoline contains a higher level of
detergents to further aide in mini-
mizing engine and fuel system de-
posits. When available, the usage of
Top Tier Detergent gasoline is recom-
mended.

use

cleaning
agents
should be avoided. Many of these materials intended
for gum and varnish removal may contain active sol-
vents or similar ingredients. These can harm fuel sys-
tem gasket and diaphragm materials.
Gasoline/Oxygenate Blends
Some
fuel
suppliers
blend
unleaded
gasoline
with
oxygenates such as ethanol.
CAUTION!
DO NOT use gasoline containing methanol or gaso-
line containing more than 10% ethanol (E-10). Use
of these blends may result in starting and drivabil-
ity problems, damage critical fuel system compo-
nents, cause emissions to exceed the applicable
standard, and/or cause the “Malfunction Indicator
Light” to illuminate. Please observe pump labels as
they should clearly communicate if a fuel contains
greater than 10% ethanol (E-10).
Problems that result from using gasoline containing
more than 10% ethanol (E-10) or gasoline containing
methanol are not the responsibility of the manufacturer
and may void or not be covered under New Vehicle
Limited Warranty.

E-85 Usage In Non-Flex Fuel Vehicles
Non-Flex Fuel Vehicles (FFV) are compatible with gaso-
line containing up to 10% ethanol (E-10). Gasoline with
higher ethanol content may void the New Vehicle
Limited Warranty.
If a Non-FFV vehicle is inadvertently fueled with E-85
fuel, the engine will have some or all of these symp-
toms:
Operate in a lean mode.
OBD II “Malfunction Indicator Light” on.
Poor engine performance.
Poor cold start and cold drivability.
Increased risk for fuel system component corrosion.
CNG And LP Fuel System Modifications
Modifications that allow the engine to run on com-
pressed natural gas (CNG) or liquid propane (LP) may
result in damage to the engine, emissions, and fuel
system components. Problems that result from running
CNG or LP are not the responsibility of the manufac-
turer and may void or not be covered under the New
Vehicle Limited Warranty.
MMT In Gasoline
Methylcyclopentadienyl
Manganese
Tricarbonyl
(MMT) is a manganese-containing metallic additive
that is blended into some gasoline to increase octane.
Gasoline blended with MMT provides no performance
advantage beyond gasoline of the same octane number
without MMT. Gasoline blended with MMT reduces
spark plug life and reduces emissions system perfor-
mance
in
some
vehicles.
The
manufacturer
recom-
mends that gasoline without MMT be used in your
vehicle. The MMT content of gasoline may not be
indicated on the gasoline pump; therefore, you should
ask your gasoline retailer whether the gasoline contains
MMT. MMT is prohibited in Federal and California
reformulated gasoline.
Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your vehicle’s
performance:
The use of leaded gasoline is prohibited by Fed-
eral law. Using leaded gasoline can impair engine
