2018 Alfa Romeo 4C Spider ECO mode

In Race mode, the transmission only works in MANUAL
mode.
Deactivation
To deactivate Race mode and return to Dynamic mode,
move the Alfa DNA system lever downwards (to letter
“A”) and keep it in this position for half a second.
The LED corresponding to Dynamic mode will light up
and the Dynamic mode activation indication will ap-
pear on the display.
Natural Mode
Electronic Stability Control (ESC) and Anti-Slip
Regulation (ASR) systems:
ESC and ASR system thresholds are aimed at providing
comfort and safety in normal grip and driving condi-
tions.
Electronic Q2 system:
The system is calibrated to ensure the best driving
comfort.
Engine And Gearbox/Transmission:
Standard response shifting.
All Weather Mode
Activation
Move the Alfa DNA system lever downwards (to the
letter “A”) and hold in this position for half a second,
until the corresponding LED lights up and the All
Weather mode activation indicator appears on the dis-
play.
Electronic Stability Control (ESC) and Anti-Slip
Regulation (ASR) systems:
ESC and ASR system thresholds are aimed at ensuring
maximum safety in low-grip driving conditions. It is
advisable to select All Weather mode in the presence of
low-grip road surfaces.
Electronic Q2 System:
The system is deactivated.
Engine And Gearbox/Transmission:
Standard response shifting.
Deactivation
To deactivate All Weather mode and return to Natural
mode, move the Alfa DNA system lever upwards (to
letter “D”) and keep it in this position for half a second.

STARTING AND OPERATING 151

NOTE:
•When the engine is next started, All Weather mode or
Natural mode will be retained when the vehicle is
restarted.
• When the engine is next started, Race mode or
Dynamic mode previously selected is not retained.
The system will reactivate in Natural mode.
• It is not possible to go directly from Dynamic mode
to All Weather mode and vice versa. You must
always first go back to Natural mode and then select
the other mode.
System Failure
In the event of system failure or a fault with the gear
selector, no driving modes can be selected.
The display will become grey (same screen as Natural
mode) but without an indication of the Alfa DNA
setting. The display will also show a warning message.
Please contact your authorized dealer for service.
Launch Control
The Launch Control strategy permits high-performance
acceleration from stand still. This strategy can be activated with vehicle at a stand-
still, Race mode selected and FIRST (1st) gear engaged.
The sequence of operations to perform is as follows:
1. Press the brake pedal and hold it down.
2. Press the accelerator pedal and hold it down.
3. Press the
–paddle behind the steering wheel. (This
allows the engine to rev above the 3000 RPM limit.)
When the brake pedal is released, the vehicle will start
with maximum acceleration. Despite the MANUAL
mode, the vehicle will automatically shift the gear to
guarantee maximum acceleration, once the correct shift-
ing speed has been reached.
WARNING!
Launch Control is intended for off-highway or
off-road use only and should not be used on any
public roadways. Use Launch Control only in a
controlled and dry track environment; within the
limits of the law. Actual Launch Control perfor-
mance may change depending on the surface and
current traction conditions. The capabilities of the

152 STARTING AND OPERATING

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.
Tread Wear Indicators
Tread wear indicators are in the original equipment
tires to help you in determining when your tires should
be replaced.
242 SERVICING AND MAINTENANCE

CAUTION!
To avoid damage to your vehicle or tires, observe
the following precautions:
•Because of restricted traction device clearance
between tires and other suspension components,
it is important that only traction devices in good
condition are used. Broken devices can cause
serious damage. Stop the vehicle immediately if
noise occurs that could indicate device breakage.
Remove the damaged parts of the device before
further use.
• 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).

CAUTION! (Continued)
•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. 8

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
