2018 Alfa Romeo 4C ECO mode

Consult an authorized tire dealer for tire repairs and
additional information.
Damaged Run Flat tires, or Run Flat tires that have
experienced a loss of pressure should be replaced
immediately with another Run Flat tire of identical size
and service description (Load Index and Speed Sym-
bol).
Run Flat Tires — If Equipped
Run Flat tires allow you the capability to drive 50 miles
(80 km) at 50 mph (80 km/h) after a rapid loss of
inflation pressure. This rapid loss of inflation is referred
to as the Run Flat mode. A Run Flat mode occurs when
the tire inflation pressure is of/or below 14 psi (96 kPa).
Once a Run Flat tire reaches the run flat mode it has
limited driving capabilities and needs to be replaced
immediately. A Run Flat tire is not repairable.
It is not recommended driving a vehicle loaded at full
capacity or to tow a trailer while a tire is in the run flat
mode.
See the tire pressure monitoring section for more infor-
mation.
Tire Spinning
When stuck in mud, sand, snow, or ice conditions, do
not spin your vehicle’s wheels above 30 mph (48 km/h)
or for longer than 30 seconds continuously without
stopping.
Refer to “Freeing A Stuck Vehicle” in “In Case Of
Emergency” for further information.
WARNING!
Fast spinning tires can be dangerous. Forces gener-
ated by excessive wheel speeds may cause tire
damage or failure. A tire could explode and injure
someone. Do not spin your vehicle’s wheels faster
than 30 mph (48 km/h) for more than 30 seconds
continuously when you are stuck, and do not let
anyone near a spinning wheel, no matter what the
speed.

CAUTION!(Continued)
•Install device as tightly as possible and then
retighten after driving about ½ mile (0.8 km).
• Do not exceed 30 mph (48 km/h).
• Drive cautiously and avoid severe turns and large
bumps, especially with a loaded vehicle.
• Do not drive for prolonged period on dry pave-
ment.
• Observe the traction device manufacturer ’s in-
structions on the method of installation, operat-
ing speed, and conditions for use. Always use the
suggested operating speed of the device manufac-
turer ’s if it is less than 30 mph (48 km/h).
• Do not use traction devices on a compact spare
tire.
Tire Rotation Recommendations
Due to tire design and size, tire rotations on this vehicle
are not possible. NOTE:
For AR 4C models, where available, the vehicle
may be equipped with high performance tires that
guarantee high grip performance with little increase of
wear. Alfa Romeo, in collaboration with Pirelli, devel-
oped a specific high performance tire for the 4C model.
A dedicated Pirelli PZero, identified with an AR mark,
guarantees this vehicle to obtain the highest perfor-
mance capable.

TIRE QUALITY GRADES
The following tire grading categories were estab-
lished by the National Highway Traffic Safety Ad-
ministration. 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
238 SERVICING AND MAINTENANCE

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
performance and damage the emissions control
system.
• An out-of-tune engine or certain fuel or ignition
malfunctions can cause the catalytic converter to
overheat. If you notice a pungent burning odor or
some light smoke, your engine may be out of tune
or malfunctioning and may require immediate
