2017 FIAT 500 flat tire

These indicators are molded into the bottom of the tread
grooves. They will appear as bands when the tread
depth becomes a 1/16 of an inch (1.6 mm). When the
tread is worn to the tread wear indicators, the tire
should be replaced. Refer to “Replacement Tires” in this
section for further information.
Life Of Tire
The service life of a tire is dependent upon varying
factors including, but not limited to:
•Driving style.
• Tire pressure - Improper cold tire inflation pressures
can cause uneven wear patterns to develop across the
tire tread. These abnormal wear patterns will reduce
tread life, resulting in the need for earlier tire replace-
ment.
• Distance driven.
• Performance tires, tires with a speed rating of V or
higher, and Summer tires typically have a reduced
tread life. Rotation of these tires per the vehicle
maintenance schedule is highly recommended.
WARNING!
Tires and the spare tire should be replaced after six
years, regardless of the remaining tread. Failure to
follow this warning can result in sudden tire fail-
ure. You could lose control and have a collision
resulting in serious injury or death.

STARTING AND OPERATING 227

Keep dismounted tires in a cool, dry place with as little
exposure to light as possible. Protect tires from contact
with oil, grease, and gasoline.
Replacement Tires
The tires on your new vehicle provide a balance of
many characteristics. They should be inspected regu-
larly for wear and correct cold tire inflation pressures.
The manufacturer strongly recommends that you use
tires equivalent to the originals in size, quality and
performance when replacement is needed. Refer to the
paragraph on “Tread Wear Indicator”. Refer to the Tire
and Loading Information placard or the Vehicle Certi-
fication Label for the size designation of your tire. The
Load Index and Speed Symbol for your tire will be
found on the original equipment tire sidewall. See the
Tire Sizing Chart example found in the “Tire Safety
Information” section of this manual for more informa-
tion relating to the Load Index and Speed Symbol of a
tire.
It is recommended to replace the two front tires or two
rear tires as a pair. Replacing just one tire can seriously
affect your vehicle’s handling. If you ever replace a
wheel, make sure that the wheel’s specifications match
those of the original wheels.It is recommended you contact your authorized tire
dealer or original equipment dealer with any questions
you may have on tire specifications or capability. Fail-
ure to use equivalent replacement tires may adversely
affect the safety, handling, and ride of your vehicle.
WARNING!
•
Do not use a tire, wheel size or rating other than
that specified for your vehicle. Some combina-
tions of unapproved tires and wheels may change
suspension dimensions and performance charac-
teristics, resulting in changes to steering, han-
dling, and braking of your vehicle. This can cause
unpredictable handling and stress to steering and
suspension components. You could lose control
and have a collision resulting in serious injury or
death. Use only the tire and wheel sizes with load
ratings approved for your vehicle.
• Never use a tire with a smaller load index or
capacity, other than what was originally equipped
on your vehicle. Using a tire with a smaller load
index could result in tire overloading and failure.
You could lose control and have a collision.

228 STARTING AND OPERATING

WARNING!
The temperature grade for this tire is established
for a tire that is properly inflated and not over-
loaded. Excessive speed, under-inflation, or exces-
sive loading, either separately or in combination,
can cause heat buildup and possible tire failure.
TIRE PRESSURE MONITORING SYSTEM (TPMS)
The Tire Pressure Monitor System (TPMS) will warn the
driver of a low tire pressure based on the vehicle
recommended cold tire pressure.
The tire pressure will vary with temperature by about 1
psi (7 kPa) for every 12°F (6.5°C). This means that when
the outside temperature decreases, the tire pressure will
decrease. Tire pressure should always be set based on
cold inflation tire pressure. This 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 a
three hour period. The cold tire inflation pressure must
not exceed the maximum inflation pressure molded into
the tire sidewall. Refer to “Tires – General Information”
in “Starting And Operating” for information on how to
properly inflate the vehicle’s tires. The tire pressure willalso 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
232 STARTING AND OPERATING

(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
(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 situa-
tion, 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.
(Continued)
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.

STARTING AND OPERATING 233

•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.
TPM System With Comfort Cluster
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. The TPMS consists of the following components:
•
Receiver Module
• Four Tire Pressure Monitoring Sensors
• Tire Pressure Monitoring Telltale Light
• Text Message Display
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 “Low inflation pressure left or right
front/rear tire” 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 infor-
mation.
234 STARTING AND OPERATING

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, an audible chime will be
activated 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 follow-
ing scenarios:
•Jamming due to electronic devices or driving next to
facilities emitting the same radio frequencies as the
TPM sensors.
• Installing some form of aftermarket window tinting
that affects radio wave signals.
• Snow or ice around the wheels or wheel housings.
• Using tire chains on the vehicle.
• Using wheels/tires not equipped with TPM sensors.
NOTE: Your vehicle may be equipped with a compact
spare wheel and tire assembly. •
The compact spare tire does not have a tire pressure
monitoring sensor. Therefore, the TPMS will not
monitor the tire pressure in the compact spare tire.
• If you install the compact spare tire in place of a road
tire that has a pressure below the low-pressure
warning limit, upon the next ignition key cycle, a
chime will sound, the Tire Pressure Monitoring Tell-
tale Light and the Low inflation pressure left or right
front / rear tire message will still turn ON due to the
low tire.
• However, after driving the vehicle for up to 20
minutes 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.
• This occurs 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 “Service Tire Pressure
Monitoring System” message will be displayed.
• Once you repair or replace the original road tire and
reinstall it on the vehicle in place of the compact
5
STARTING AND OPERATING 235

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.

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 instrument
cluster will display a low pressure text message and
a graphic showing the low tire pressure tire high-
lighted in a different color.
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
