2012 FIAT FREEMONT brake sensor

ELECTRONIC ROLL MITIGATION (ERM)
This system anticipates the potential for wheel lift by
monitoring the driver’s steering wheel input and the
speed of the vehicle. When ERM determines that the
rate of change of the steering wheel angle and vehicle's
speed are sufficient to potentially cause wheel lift, it
then applies the appropriate brake and may also reduce
engine power to lessen the chance that wheel lift will
occur. ERM will only intervene during very severe or
evasive driving maneuvers. ERM can only reduce the
chance of wheel lift occurring during severe or evasive
driving maneuvers. It cannot prevent wheel lift due to
other factors, such as road conditions, leaving the
roadway, or striking objects or other vehicles.
WARNING!
Many factors, such as vehicle loading,
road conditions, and driving conditions,
influence the chance that wheel lift or rollover
may occur. ERM cannot prevent all wheel lift or
rollovers, especially those that involve leaving the
roadway or striking objects or other vehicles.The
capabilities of an ERM-equipped vehicle must
never be exploited in a reckless or dangerous
manner, which could jeopardize the user's safety
or the safety of others. ELECTRONIC STABILITY CONTROL (ESC)
This system enhances directional control and stability
of the vehicle under various driving conditions. ESC
corrects for over-steering and under-steering the ve-
hicle by applying the brake of the appropriate wheel.
Engine power may also be reduced to help the vehicle
maintain the desired path.
The ESC uses sensors in the vehicle to determine the
path that the driver intends to steer the vehicle and
compares it to the actual path of the vehicle. When the
actual path does not match the intended path, the ESC
applies the brake of the appropriate wheel to assist in
counteracting the condition of over-steer or under-
steer.
• Over-steer - when the vehicle is turning more than
appropriate for the steering wheel position.
• Under-steer - when the vehicle is turning less than appropriate for the steering wheel position.
WARNING!
 Electronic Stability Control (ESC)
cannot prevent the natural laws of phys-
ics from acting on the vehicle, nor can it increase
the traction afforded by prevailing road condi-
tions.

WARNING!
When in “Partial Off ” mode, the TCS
functionality of ESC, (except for the lim-
ited slip feature described in the TCS section), has
been disabled and the “ESC Off Indicator Light”
will be illuminated. All other stability features of
ESC function normally. When in “Partial Off ”
mode, the engine power reduction feature of TCS
is disabled, and the enhanced vehicle stability
offered by the ESC system is reduced.
ESC ACTIVATION/MALFUNCTION
INDICATOR LIGHT AND ESC OFF
INDICATOR LIGHT The “ESC Activation/Malfunction Indicator
Light” in the instrument cluster will come on
when the ignition switch is turned to the ON
position. It should go out with the engine
running. If the “ESC Activation/Malfunction Indicator
Light” comes on continuously with the engine running,
a malfunction has been detected in the ESC system. If
this light remains on after several ignition cycles, and
the vehicle has been driven several kilometers at
speeds greater than 48 km/h, see your authorized
dealer as soon as possible to have the problem diag-
nosed and corrected.
The “ESC Activation/Malfunction Indicator Light” (lo-
cated in the instrument cluster) starts to flash as soon as the tires lose traction and the ESC system becomes
active. The “ESC Activation/Malfunction Indicator
Light” also flashes when TCS is active. If the “ESC
Activation/Malfunction Indicator Light” begins to flash
during acceleration, ease up on the accelerator and
apply as little throttle as possible. Be sure to adapt your
speed and driving to the prevailing road conditions.
NOTE:
• The “ESC Activation/Malfunction Indicator Light”
and the “ESC OFF Indicator Light” come on momen-
tarily each time the ignition switch is turned ON.
• Each time the ignition is turned ON, the ESC system
will be ON even if it was turned off previously.
• The ESC system will make buzzing or clicking sounds
when it is active. This is normal; the sounds will stop
when ESC becomes inactive following the maneuver
that caused the ESC activation.
The “ESC OFF Indicator Light” indicates the
Electronic Stability Control (ESC) is off.
TRAILER SWAY CONTROL (TSC)
TSC uses sensors in the vehicle to recognize an exces-
sively swaying trailer. TSC activates automatically once
the excessively swaying trailer is recognized. When
TSC is functioning, the “ESC Activation/Malfunction
Indicator Light” will flash, the engine power will be
reduced, and you will feel the brake being applied to

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 . (Re-
fer to “Tire Inflation Pressures” under “Tires —
General Information” and to “Tire Pressure Moni-
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.
