2012 FIAT FREEMONT TPMS

TIRE PRESSURE MONITOR SYSTEM (TPMS)
The Tire Pressure Monitor System (TPMS) will warn
the driver of a low tire pressure based on the vehicle
recommended cold placard pressure.
The tire pressure will vary with temperature by about
0.069 BAR for every 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 1.6 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 “Technical Specifications” for informa-
tion on how to properly inflate the vehicle’s tires. The
tire pressure will also increase as the vehicle is driven.
This is normal and there should be no adjustment for
this increased pressure.
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
and 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 placard pressure. Once the lowtire pressure warning (Tire Pressure Monitoring Tell-
tale Light) illuminates, you must increase the tire pres-
sure to the recommended cold placard 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 25 km/h in order for the TPMS to receive this
information.
 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 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. Do not use aftermarket tire sealants or
balance beads if your vehicle is equipped with a
TPMS, as damage to the sensors may result .
 After inspecting or adjusting the tire pressure,
always reinstall the valve stem cap.This will pre-
vent moisture and dirt from entering the valve
stem, which could damage theTire Pressure Moni-
toring 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 pressure
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 pres-
sure in the tire.
BASE SYSTEM
The Tire Pressure Monitor System (TPMS) uses wire-
less 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.NOTE:
It is particularly important for you to check
the tire pressure in all of the tires on your vehicle
monthly 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
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. 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 pres-
sure value. Once the system receives the updated tire
pressures, the system will automatically update and the
Tire Pressure Monitoring Telltale Light will turn off.
The vehicle may need to be driven for up to 20 minutes
above 25 km/h in order for the TPMS to receive this
information.
Check TPMS Warning
When a system fault is detected, the Tire Pressure
Monitoring Telltale Light will flash on and off for 75 sec-
onds and then remain on solid. The system fault will
also sound a chime. If the ignition switch 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 due to any of the following:
1. Jamming due to electronic devices or driving next tofacilities emitting the same Radio Frequencies as the
TPMS sensors.
2. Installing some form of aftermarket window tinting that affects radio wave signals.
3. Lots of snow or ice around the wheels or wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPMS sensors.
NOTE:
1. The compact spare tire does not have a tire pres-
sure monitoring sensor. Therefore, the TPMS will not
monitor the 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, a chime will sound and the TPMS Telltale Light
will turn on upon the next ignition switch cycle.
3. After driving the vehicle for up to 20 minutes above
25 km/h, the TPMS Telltale Light will flash on and off for
75 seconds and then remain on solid.
4. For each subsequent ignition switch cycle, a chime
will sound and the TPMS Telltale Light will flash on and
off for 75 seconds and then remain on solid. 5. Once you repair or replace the original road tire and
reinstall it on the vehicle in place of the compact spare,
the TPMS will update automatically and the TPMS
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 25 km/h in order for the TPMS
to receive this information.
TPMS Deactivation And Reactivation
The TPMS can be deactivated if replacing all four wheel
and tire assemblies (road tires) with wheel and tire
assemblies that do not have TPMS Sensors, such as
when installing winter wheel and tire assemblies on
your vehicle.
To deactivate the TPMS, first, replace all four wheel and
tire assemblies (road tires) with those not equipped
with TPM Sensors. Then, drive the vehicle for at least
20 minutes above 25 km/h. The TPMS will chime and
the TPM Telltale Light will flash on and off for 75 sec-
onds and then remain on solid. Upon the next ignition
switch cycle, the TPMS will no longer chime or turn on
the Tire Pressure Monitoring Telltale Light.
To reactivate the TPMS, first, replace all four wheel and
tire assemblies (road tires) with those equipped with
TPM Sensors. Then, drive the vehicle for up to 20 min-
utes above 25 km/h. The TPMS will chime and the Tire
Pressure Monitoring Telltale Light will flash on and off
for 75 seconds.

• 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 dis- play a graphic showing the pressure values of each tire
with the low tire pressure values flashing. (fig. 101)
Should this occur, you should stop as soon as possible
and inflate the tires with low pressure (those flashing in
the EVIC graphic) to the vehicle’s recommended cold
placard pressure value. Once the system receives the
updated tire pressures, the system will automatically
update, the graphic display in the EVIC will stop flash-
ing, and the Tire Pressure Monitoring Telltale Light will
turn off. The vehicle may need to be driven for up to
20 minutes above 25 km/h in order for the TPMS to

also sound a chime. In addition, the EVIC will display a
"CHECK TPM SYSTEM" message for three seconds
and then display dashes (- -) in place of the pressure
value to indicate which sensor is not being received.
(fig. 102)
If the ignition switch is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault
no longer exists, the Tire Pressure Monitoring Telltale
Light will no longer flash, and the "CHECK TPM SYS-
TEM" message will no longer display, and a pressure
value will display in place of the dashes. A system fault
can occur due to any of the following:
1. Jamming due to electronic devices or driving next tofacilities emitting the same radio frequencies as the
TPMS sensors. 2. Installing some form of aftermarket window tinting
that affects radio wave signals.
3. Lots of snow or ice around the wheels or wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPMS sensors.
NOTE:
1. The compact spare tire does not have a tire pres-
sure monitoring sensor. Therefore, the TPMS will not
monitor the 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 switch cycle, the TPMS
Telltale Light will remain on and a chime will sound. In
addition, the graphic in the EVIC will still display a
flashing pressure value.
3. After driving the vehicle for up to 20 minutes above
25 km/h, the TPMS Telltale Light will flash on and off for
75 seconds and then remain on solid. In addition, the
EVIC will display a "CHECK TPM SYSTEM" message

the pressure value.
5. Once you repair or replace the original road tire and
reinstall it on the vehicle in place of the compact spare,
the TPMS will update automatically. In addition, the
TPMS Telltale Light will turn off and the graphic in the
EVIC will display a new pressure value instead of dashes
(- -), 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 25 km/h in order for the TPMS to
receive this information.
TPMS Deactivation And Reactivation
The TPMS can be deactivated if replacing all four wheel
and tire assemblies (road tires) with wheel and tire
assemblies that do not have TPMS Sensors, such as
when installing winter wheel and tire assemblies on
your vehicle.
To deactivate the TPMS, first, replace all four wheel and
tire assemblies (road tires) with those not equipped
with TPM Sensors. Then, drive the vehicle for 20 min-
utes above 25 km/h. The TPMS will chime and the Tire
Pressure Monitoring Telltale Light will flash on and off
for 75 seconds and then remain on solid. In addition,
the Electronic Vehicle Information Center (EVIC) will
display a “CHECK TPM SYSTEM” text message, and
the graphic will display “- -“ in place of four tire
pressure values. Upon the next ignition switch cycle,
the TPMS will no longer chime or turn on the TirePressure Monitoring Telltale Light, or display the text
message in the EVIC. However, the graphic will still
display “- -.“
To reactivate the TPMS, first, replace all four wheel and
tire assemblies (road tires) with those equipped with
TPM Sensors. Then, drive the vehicle for up to 20 min-
utes above 25 km/h. The TPMS will chime, the Tire
Pressure Monitoring Telltale Light will flash on and off
for 75 seconds, the EVIC will display a “CHECK TPM
SYSTEM” text message, and the graphic will display tire
pressure values to show that the TPMS is receiving
sensor data.
GENERAL INFORMATION
Transmitter and receivers operate on a carrier fre-
quency of 433.92 MHz as required by EEC regulations.
These devices must be certified to conform to specific
regulations in each individual country. Two sets of
regulations are involved: ETS (European Telecommuni-
cation Standard) 300–220, which most countries use,
and German BZT federal regulation 225Z125, which is
based on ETC 300–220 but has additional unique re-
quirements. Other defined requirements are noted in
ANNEX VI of COMMISSION DIRECTIVE 95/56/EC.
Operation is subject to the following two conditions:
• This device may not cause harmful interference.
• This device must accept any interference received,
including interference that may cause undesired operation.

8. Park/Headlight ON Indicator (for
versions/markets, where provided)This indicator will illuminate when the park
lights or headlights are turned on. (Refer to
“Lights” in “Knowing Your Vehicle” for fur-
ther information).
9. Tire Pressure Monitoring Telltale Light (for
versions/markets, where provided) Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the
vehicle placard or tire inflation pressure label. (If your
vehicle has tires of a different size than the size indi-
cated on the vehicle placard or tire inflation pressure
label, you should determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system
(TPMS) that illuminates a low tire pressure telltale
when one or more of your tires is significantly under-
inflated. Accordingly, when the low tire pressure tell-
tale light illuminates, you should stop and check your
tires as soon as possible, and inflate them to the proper
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. Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver’s respon-
sibility to maintain correct tire pressure, even if under-
inflation has not reached the level to trigger illumina-
tion 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 indica-
tor is combined with the low tire pressure telltale.
When the system detects a malfunction, the telltale
will flash for approximately one minute and then re-
main continuously illuminated. This sequence will con-
tinue 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 reasons, including the instal-
lation of replacement or alternate tires or wheels on
the vehicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunction telltale
light after replacing one or more tires or wheels on
your vehicle to ensure that the replacement or alter-
nate tires and wheels allow the TPMS to continue to
function properly.

tor System (TPMS)” in “Technical Specifications”
for further information).
10. Seat Belt Reminder Light When the ignition switch is first turned to ON/
RUN, this light will turn on for four to eight
seconds as a bulb check. During the bulb check,
if the driver's seat belt is unbuckled, a chime will sound.
After the bulb check or when driving, if the driver seat
belt remains unbuckled, the Seat Belt Warning Light
will flash or remain on continuously. Refer to “Occu-
pant Restraints” in “Safety” for further information. 11. Brake Warning Light
This light monitors various brake functions,
including brake fluid level and parking brake
application. If the brake light turns on it may
indicate that the parking brake is applied, that
the brake fluid level is low, or that there is a problem
with the anti-lock brake system reservoir.
If the light remains on when the parking brake has been
disengaged, and the fluid level is at the full mark on the
master cylinder reservoir, it indicates a possible brake
hydraulic system malfunction or that a problem with
the Brake Booster has been detected by the Anti-Lock
Brake System (ABS) / Electronic Stability Program
(ESP) system. In this case, the light will remain on until
the condition has been corrected. If the problem is
related to the brake booster, the ABS pump will run
when applying the brake and a brake pedal pulsation
may be felt during each stop.
The dual brake system provides a reserve braking
capacity in the event of a failure to a portion of the
hydraulic system. A leak in either half of the dual brake
system is indicated by the Brake Warning Light, which
will turn on when the brake fluid level in the master
cylinder has dropped below a specified level.
The light will remain on until the cause is corrected.
NOTE: The light may flash momentarily during sharp
cornering maneuvers, which change fluid level condi-
tions. The vehicle should have service performed, and
the brake fluid level checked.
