2017 Alfa Romeo 4C Spider sensor

General Warnings
When parking, take the utmost care over obstacles that
may be above or under the sensor.
Under certain circumstances, objects close to the vehicle
are not detected by the system and could therefore
cause damage to the vehicle or be damaged themselves.
Some conditions may influence the performance of the
parking sensors:
•The presence of ice, snow, mud or multiple layers of
paint on the sensor surface may cause reduced
sensitivity of the sensor itself and therefore reduce
the system performance.
• Mechanical interference (e.g washing the vehicle,
rain, strong wind, hail) may cause the sensor to
detect a non-existent obstacle (“echo interference”).
• The presence of ultrasonic systems (e.g. pneumatic
brake systems of trucks or pneumatic drills) near the
vehicle could alter the signals sent by the sensor. •
The variation in sensor position, caused by variation
in ride (due to suspension component wear), chang-
ing tires, overloaded vehicle, or tuning that lowers
the vehicle, for example, may affect parking sensor
system performance.
NOTE: The sensor must be free from mud, dirt snow or
ice in order for the system to operate correctly. Be
careful not to scratch or damage the sensors while
cleaning them. Avoid using dry, rough or hard cloths.
The sensors must be washed using clean water, with the
addition of car shampoo if necessary. When using
special washing equipment such as high pressure jets or
steam cleaning, clean the sensors very quickly keeping
the jet more than 4 in (10 cm) away. Also, do not apply
stickers to the sensors.
WARNING!
Drivers must be careful when backing up even when
using the Parking Sensor system. Always check care-
fully behind your vehicle, and be sure to check for
pedestrians, animals, other vehicles, obstructions, or
blind spots before backing up. You are responsible

for the safety of your surroundings and must con-
tinue to pay attention while backing up. Failure to do
so can result in serious injury or death.
CAUTION!
•The Parking Sensor system is only a parking aid
and it is unable to recognize every obstacle,
including small obstacles. Parking curbs might be
temporarily detected or not detected at all. Ob-
stacles located above or below the sensors will
not be detected when they are in close proximity
• The vehicle must be driven slowly when using
the Parking Sensor system in order to be able to
stop in time when an obstacle is detected. It is
recommended that the driver looks over his/her
shoulder when using the Parking Sensor system.
POWER OUTLETS
Your vehicle is equipped with a 12 Volt (13 Amp) power
outlet that can be used to power cellular phones, small
electronics and other low powered electrical accessories.

Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver ’s responsibility to
maintain correct tire pressure, even if under-inflation
has not reached the level to trigger illumination of the
TPMS low tire pressure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system is
not operating properly. The TPMS malfunction indi-
cator is combined with the low tire pressure telltale.
When the system detects a malfunction, the telltale
will flash for approximately one minute and then
remain continuously illuminated. This sequence will
continue upon subsequent vehicle start-ups as long
as the malfunction exists. When the malfunction
indicator is illuminated, the system may not be able
to detect or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of rea-
sons, including the installation of replacement or
alternate tires or wheels on the vehicle that prevent
the TPMS from functioning properly. Always check
the TPMS malfunction telltale after replacing one or
more tires or wheels on your vehicle, to ensure that
the replacement or alternate tires and wheels allow
the TPMS to continue to function properly.
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 op-
eration or sensor damage may result when using
replacement 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.

WARNING!(Continued)
in a reckless or dangerous manner which could
jeopardize the user ’s safety or the safety of others.
• Vehicle modifications, or failure to properly
maintain your vehicle, may change the handling
characteristics of your vehicle, and may nega-
tively affect the performance of the ESC system.
Changes to the steering system, suspension, brak-
ing system, tire type and size or wheel size may
adversely affect ESC performance. Improperly
inflated and unevenly worn tires may also de-
grade ESC performance. Any vehicle modifica-
tion 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 trajectory, 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.
• Understeer: occurs when the vehicle is turning less
than it should according to the angle of the steering
wheel.
This vehicle’s advanced electronic brake control system
also includes: Electronic Brake Distribution (EBD), Anti-
Lock Brake System (ABS), Cornering Brake Control
System (CBC), Drag Torque Control System (DTC),
AntiSlip Regulation System (ASR), Hill Start Assist
(HSA), Hydraulic Brake Assistant System (HBA),
ELECTRONIC Q2 system (E-Q2) and Ready Alert Brake
(RAB). All of the systems work together to enhance
vehicle stability and control in various driving condi-
tions, and are commonly referred to as ESC.
System Activation
The ESC system activates automatically when the en-
gine is started and can only be deactivated by selecting
Race mode. Refer to the Six-Speed Alfa Twin Clutch
Transmission in this section for further information.

also increase as the vehicle is driven, this is normal and
there should be no adjustment for this increased pres-
sure.
The TPMS will warn the driver of a low tire pressure if
the tire pressure falls below the low pressure warning
limit for any reason, including low temperature effects,
or natural pressure loss through the tire.
The TPMS will continue to warn the driver of low tire
pressure as long as the condition exists, and will not
turn off until the tire pressure is at or above the
recommended cold tire pressure on the placard. Once
the low tire pressure warning (Tire Pressure Monitoring
Telltale Light) illuminates, you must increase the tire
pressure to the recommended cold tire pressure in order
for the Tire Pressure Monitoring Telltale Light to turn
off. The system will automatically update and the Tire
Pressure Monitoring Telltale Light will turn off once the
system receives the updated tire pressures. The vehicle
may need to be driven for up to 20 minutes above
15 mph (24 km/h) in order for the TPMS to receive this
information.
For example, your vehicle may have a recommended cold
(parked for more than three hours) tire pressure of 30 psi
(207 kPa). If the ambient temperature is 68°F (20°C) andthe measured tire pressure is 27 psi (186 kPa), a tempera-
ture drop to 20°F (-7°C) will decrease the tire pressure to
approximately 23 psi (159 kPa). This tire pressure is
sufficiently low enough to turn on the Tire Pressure
Monitoring Telltale Light. Driving the vehicle may cause
the tire pressure to rise to approximately 27 psi (186 kPa),
but the Tire Pressure Monitoring Telltale Light will still be
on. In this situation, the Tire Pressure Monitoring Telltale
Light will turn off only after the tires are inflated to the
vehicle’s recommended cold tire pressure value.
CAUTION!
•
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warnings have been established for the tire size
equipped on your vehicle. Undesirable system
operation or sensor damage may result when
using replacement 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.

186 STARTING AND OPERATING

CAUTION!(Continued)
After using an aftermarket tire sealant it is recom-
mended that you take your vehicle to an autho-
rized dealership to have your sensor function
checked.
• After inspecting or adjusting the tire pressure,
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the valve
stem, which could damage the Tire Pressure
Monitoring Sensor.
NOTE:
• The TPMS is not intended to replace normal tire care
and maintenance, or to provide warning of a tire
failure or condition.
• The TPMS should not be used as a tire pressure
gauge while adjusting your tire pressure.
• Driving on a significantly under-inflated tire causes
the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency and tire
tread life, and may affect the vehicle’s handling and
stopping ability. •
The TPMS is not a substitute for proper tire mainte-
nance, and it is the driver ’s responsibility to maintain
correct tire pressure using an accurate tire gauge,
even if under-inflation has not reached the level to
trigger illumination of the Tire Pressure Monitoring
Telltale Light.
• Seasonal temperature changes will affect tire pres-
sure, and the TPMS will monitor the actual tire
pressure in the tire.
Base System
This is the TPMS warning indicator located in
the instrument cluster.
The TPMS uses wireless technology with wheel rim
mounted electronic sensors to monitor tire pressure
levels. Sensors, mounted to each wheel as part of the
valve stem, transmit tire pressure readings to the Re-
ceiver Module.
NOTE: It is particularly important for you to check the
tire pressure in all of the tires on your vehicle regularly
and to maintain the proper pressure.
