2015 FIAT 500 ABARTH sensor

Turn the ignition switch to the AVV/ACC (START)
position and release it when the engine starts. If the
engine fails to start within 10 seconds, turn the ignition
switch to the STOP (OFF/LOCK) position, wait 10 to
15 seconds, then repeat the “Normal Starting” procedure.
Cold Weather Operation
To prevent possible engine damage while starting at low
temperatures, this vehicle will inhibit engine cranking
when the ambient temperature is less than –22° F (–30° C)
and the oil temperature sensor reading indicates an
engine block heater has not been used. An externally-
powered electric engine block heater is available as
optional equipment or from your authorized dealer.
The message “plug in engine heater” will be displayed in
the instrument cluster when the ambient temperature is
below 5° F (–15° C) at the time the engine is shut off as a
reminder to avoid possible crank delays at the next cold
start.
CAUTION!
Use of the recommended SAE 5W-40 synthetic en-
gine oil and adhering to the prescribed oil change
intervals is important to prevent engine damage and
ensure satisfactory starting in cold conditions.
Extended Park Starting
NOTE:Extended Park condition occurs when the vehicle
has not been started or driven for at least 35 days.
1. Install a battery charger or jumper cables to the battery
to ensure a full battery charge during the crank cycle.
2. Cycle the ignition in the START position and release it
when the engine starts.
228 STARTING AND OPERATING

WARNING!
There may be situations on minor hills with a loaded
vehicle, or while pulling a trailer, when the system
will not activate and slight rolling may occur. This
could cause a collision with another vehicle or object.
Always remember the driver is responsible for brak-
ing the vehicle.
Disabling/Enabling HSA
If you wish to turn the HSA system on or off, it can be
done using the Customer Programmable Features in
the Electronic Vehicle Information Center (EVIC). Refer
to “Electronic Vehicle Information Center (EVIC)”
in “Understanding Your Instrument Panel” for further
information.
Electronic Stability Control (ESC)
The Electronic Stability Control (ESC) system enhances
directional control and stability of the vehicle under
various driving conditions. ESC corrects for oversteering
or understeering of the vehicle by applying the brake of
the appropriate wheel to assist in counteracting the
oversteering or understeering condition. Engine power
may also be reduced to help the vehicle maintain the
desired path. ESC uses sensors in the vehicle to deter-
mine the vehicle path intended by the driver and com-
pares it to the actual path of the vehicle. When the actual
path does not match the intended path, ESC applies the
brake of the appropriate wheel to assist in counteracting
the oversteer or understeer condition.
•Oversteer - when the vehicle is turning more than
appropriate for the steering wheel position.
•Understeer - when the vehicle is turning less than
appropriate for the steering wheel position.
256 STARTING AND OPERATING

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) and the measured tire pressure is 27 psi (186 kPa),
a temperature drop to 20° F (-7° C) will decrease the tire
pressure to approximately 23 psi (158 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 pres-
sure value.
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 your local dealer 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 TPM sensor.

STARTING AND OPERATING 287

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 pressure,
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 lev-
els. Sensors, mounted to each wheel as part of the valve
stem, transmit tire pressure readings to the Receiver
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.
288 STARTING AND OPERATING

The TPMS consists of the following components:
•Receiver Module.
•Four Tire Pressure Monitoring Sensors.
•Tire Pressure Monitoring Telltale Light.
Tire Pressure Monitoring Low Pressure Warnings
The Tire Pressure Monitoring Telltale Light will illumi-
nate in the instrument cluster, an audible chime will be
activated, and the “Check left or right front/rear tire
xxx.x psi” text message will display when one or more of
the four active road tire pressures are low. Should this
occur, you should stop as soon as possible, check the
inflation pressure of each tire on your vehicle, and inflate
each tire to the vehicle’s recommended cold placard
pressure value. The system will automatically update
and the Tire Pressure Monitoring Light will extinguish
once the updated tire pressures have been received. The
vehicle may need to be driven for up to 20 minutes above
15 mph (24 km/h) to receive this information.
Check TPMS Warnings
The Tire Pressure Monitoring Telltale Light will flash on
and off for 75 seconds and remain on solid when a system
fault is detected, and the “Service Tire Pressure Monitoring
System” text message will display. If the ignition key is
cycled, this sequence will repeat providing the system fault
still exists. The Tire Pressure Monitoring Telltale Light will
turn off when the fault condition no longer exists. A system
fault can occur with any of the following scenarios:
1. Jamming due to electronic devices or driving next to
facilities emitting the same radio frequencies as the
TPM sensors.
2. Installing some form of aftermarket window tinting
that affects radio wave signals.
3. Snow or ice around the wheels or wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM sensors.
5
STARTING AND OPERATING 289

NOTE:Your vehicle may be equipped with a compact
spare wheel and tire assembly.
1. The compact spare tire does not have a tire pressure
monitoring sensor. Therefore, the TPMS will not moni-
tor the tire pressure in the compact spare tire.
2. If you install the compact spare tire in place of a road
tire that has a pressure below the low-pressure warn-
ing limit, upon the next ignition key cycle, a chime will
sound and the Tire Pressure Monitoring Telltale Light
and the “Check Tire Pressure” message will still turn
ON due to the low tire.
3. However, after driving the vehicle for up to 20 min-
utes above 15 mph (24 km/h), the Tire Pressure
Monitoring Telltale Light will flash on and off for
75 seconds and then remain on solid and the#Service
Tire Pressure Monitoring System#message will be
displayed.
4. For each subsequent ignition key cycle, a chime will
sound and the Tire Pressure Monitoring Telltale Light
will flash on and off for 75 seconds and then remain on
solid and the “Tire Pressure Monitoring Unavailable”
message will be displayed.
5. Once you repair or replace the original road tire and
reinstall it on the vehicle in place of the compact spare
tire, the TPMS will update automatically and the Tire
Pressure Monitoring Telltale Light will turn OFF, as
long as no tire pressure is below the low-pressure
warning limit in any of the four active road tires. 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.
290 STARTING AND OPERATING

Enhanced TPM System
When the vehicle is equipped with an enhanced TPM
system, the driver can view text messages showing the
actual tire pressure value by position by selecting the tire
pressure menu command in the instrument cluster. Refer
to ”Instrument Panel Features” in “Understanding Your
Instrument Panel” for further information.
Premium TPM System
The Tire Pressure Monitor System (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 receiver module.
The TPMS consists of the following components:
•Receiver module
•Four Tire Pressure Monitoring Sensors
•Various Tire Pressure Monitoring System messages,
which display in the Electronic Vehicle Information
Center (EVIC)
•Tire Pressure Monitoring Telltale Light
Tire Pressure Monitoring Low Pressure Warnings
The “Tire Pressure Monitoring Telltale Light” will
illuminate in the instrument cluster and a chime will
sound when tire pressure is low in one or more of the
four active road tires. In addition, the Electronic Vehicle
Information Center (EVIC) will display a graphic show-
ing the pressure values of each tire with the low tire
pressure tire highlighted in a different color.
5
STARTING AND OPERATING 291

Should this occur, you should stop as soon as possible
and inflate the tires with low pressure to the vehicle’s
recommended cold placard pressure value. Once the
system receives the updated tire pressures, the system
will automatically update and the “Tire Pressure Moni-
toring Telltale Light” will turn off. 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 informa-
tion.
TPMS Warning
When a system fault is detected, the “Tire Pressure
Monitoring Telltale Light” will flash on and off for
75 seconds and then remain on solid. The system fault
will sound a chime and also display a “Service Tire
Pressure Monitoring System” message in the EVIC for
approximately 5 seconds and then display dashes (- -) in
place of the pressure value to indicate which sensor is not
being received.
