2016 Alfa Romeo 4C Spider tire type

CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system opera-
tion or sensor damage may result when using re-
placement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Using aftermarket tire sealants may
cause the Tire Pressure Monitoring System (TPMS)
sensor to become inoperable. After using an after-
market tire sealant it is recommended that you take
your vehicle to an authorized dealership to have your
sensor function checked.

Range
This indicates the distance which may be traveled with
the fuel remaining in the tank, assuming that driving
conditions will not change. The message “----” will
appear on the display in the following cases:
•Distance less than 30 miles (or 50 km).
• The vehicle is parked for a long time with the engine
running.
NOTE: The range depends on several factors: driving
style, type of route (freeway, residential, mountain roads,
etc.), conditions of use of the vehicle (load, tire pressure,
etc.). Trip planning must take into account the above
notes.
Average Fuel Consumption
This value shows the approximate average consumption
since the last reset.
Travel Distance
This value shows the distance covered since the last reset.
Current Fuel Consumption
This indicates the fuel consumption. The value is con-
stantly updated. The message “----” will appear on the
display if the vehicle is parked with the engine running.

WARNING! (Continued)
ESC performance. Improperly inflated and un-
evenly worn tires may also degrade ESC perfor-
mance. Any vehicle modification or poor vehicle
maintenance that reduces the effectiveness of the
ESC system can increase the risk of loss of vehicle
control, vehicle rollover, personal injury and death.
The ESC system uses sensors installed on the vehicle to
determine the trajectory that the driver intends to follow
and compares it with the vehicles effective trajectory.
When the real trajectory deviates from the desired trajec-
tory, the ESC system intervenes to counter the vehicles
understeer or oversteer.
• Oversteer: occurs when the vehicle is turning more
than it should according to the angle of the steering
wheel.

WARNING!(Continued)
compromise personal safety and the safety of oth-
ers.
• For the correct operation of the ABS, the tires must
of necessity be the same make and type on all
wheels, in perfect condition and, above all, of the
prescribed type and dimensions.
When you are in a severe braking condition involving the
use of the ABS, you will experience some pedal drop as
the vehicle comes to a stop. This is the result of the
system reverting to the base brake system.
Engagement of the ABS may be accompanied by a
pulsing sensation. You may also hear a clicking noise.
These occurrences are normal and indicate that the
system is functioning properly.
System Intervention
A slight pulsing of the brake pedal and noise indicates
the intervention of the ABS: this is completely normal
when the system intervenes.
Cornering Brake Control System (CBC)
The system acts when braking on corners, optimizing the
distribution of brake pressure on the four wheels: the
system prevents the wheels on the inside of the corner
(less affected by the weight of the vehicle) from locking,
ensuring better stability and direction for the vehicle.
Drag Torque Control System (DTC)
This is an integral part of the ESC system and intervenes
in the event of sudden downshifting, or during braking
when the ABS intervenes, restoring torque to the engine
and thus preventing excessive drag at the drive wheels,
which may lead the wheels to lock and a loss of vehicle
stability, above all in low-grip conditions.

AntiSlip Regulation System (ASR)
WARNING!
•Electronic Stability Control (ESC) cannot prevent
the natural laws of physics from acting on the
vehicle, nor can it increase the traction afforded by
prevailing road conditions. ESC cannot prevent all
collisions, including those resulting from excessive
speed in turns, driving on very slippery surfaces, or
hydroplaning. ESC also cannot prevent collisions
resulting from loss of vehicle control due to inap-
propriate driver input for the conditions. Only a
safe, attentive, and skillful driver can prevent col-
lisions.The capabilities of an ESC equipped ve-
hicle must never be exploited in a reckless or
dangerous manner which could jeopardize the us-
er ’s safety or the safety of others.

WARNING! (Continued)
•Vehicle modifications, or failure to properly main-
tain your vehicle, may change the handling charac-
teristics of your vehicle, and may negatively affect
the performance of the ESC system. Changes to the
steering system, suspension, braking system, tire
type and size or wheel size may adversely affect

evenly worn tires may also degrade ESC perfor-
mance. Any vehicle modification or poor vehicle
maintenance that reduces the effectiveness of the
ESC system can increase the risk of loss of vehicle
control, vehicle rollover, personal injury and death.
This is an integral part of the ESC system and automati-
cally operates in the event of one or both drive wheels
slipping, loss of grip on wet roads (hydroplaning) and
acceleration on slippery, snowy or icy roads, etc.
202 STARTING AND OPERATING

At least once a month:
•Check and adjust tire pressure with a good quality
pocket-type pressure gauge. Do not make a visual
judgement when determining proper inflation. Tires
may look properly inflated even when they are under-
inflated.
• Inspect tires for signs of tire wear or visible damage.
CAUTION!
After inspecting or adjusting the tire pressure, al-
ways reinstall the valve stem cap. This will prevent
moisture and dirt from entering the valve stem,
which could damage the valve stem.
Inflation pressures specified on the placard are always
“cold tire inflation pressure”. Cold tire inflation pressure
is defined as the tire pressure after the vehicle has not
been driven for at least three hours, or driven less than 1 mile (1.6 km) after sitting for a minimum of three hours.
The cold tire inflation pressure must not exceed the
maximum inflation pressure molded into the tire side-
wall.
Check tire pressures more often if subject to a wide range
of outdoor temperatures, as tire pressures vary with
temperature changes.
Tire pressures change by approximately 1 psi (7 kPa) per
12°F (7°C) of air temperature change. Keep this in mind
when checking tire pressure inside a garage, especially in
the Winter.
Example: If garage temperature = 68°F (20°C) and the
outside temperature = 32°F (0°C) then the cold tire
inflation pressure should be increased by 3 psi (21 kPa),
which equals 1 psi (7 kPa) for every 12°F (7°C) for this
outside temperature condition.

STARTING AND OPERATING 219

Tire pressure may increase from 2 to 6 psi (13 to 40 kPa)
during operation. DO NOT reduce this normal pressure
build up or your tire pressure will be too low.
Tire Pressures For High Speed Operation
The manufacturer advocates driving at safe speeds and
within posted speed limits. Where speed limits or condi-
tions are such that the vehicle can be driven at high
speeds, maintaining correct tire inflation pressure is very
important. Increased tire pressure and reduced vehicle
loading may be required for high-speed vehicle opera-
tion. Refer to your authorized tire dealer or original
equipment vehicle dealer for recommended safe operat-
ing speeds, loading and cold tire inflation pressures.
WARNING!
High speed driving with your vehicle under maxi-
mum load is dangerous. The added strain on your
tires could cause them to fail. You could have a
serious collision. Do not drive a vehicle loaded to the
maximum capacity at continuous speeds above
75 mph (120 km/h).
Radial Ply Tires
WARNING!
Combining radial ply tires with other types of tires
on your vehicle will cause your vehicle to handle
poorly. The instability could cause a collision. Al-
ways use radial ply tires in sets of four. Never
combine them with other types of tires.
