2014 FIAT FREEMONT catalytic converter

ONBOARD DIAGNOSTIC SYSTEM —
OBD II
Your vehicle is equipped with a sophisticated onboard
diagnostic system called OBD II. This system monitors
the performance of the emissions, engine, and auto-
matic transmission control systems. When these sys-
tems are operating properly, your vehicle will provide
excellent performance and fuel economy, as well as
engine emissions well within current government regu-
lations.
If any of these systems require service, the OBD II
system will turn on the “Malfunction Indicator Light”
(MIL). It will also store diagnostic codes and other
information to assist your service technician in making
repairs. Although your vehicle will usually be drivable
and not need towing, see your authorized dealer for
service as soon as possible.
•Prolonged driving with the MIL on
could cause further damage to the emis-
sion control system. It could also affect
fuel economy and driveability.The vehicle must be
serviced before any emissions tests can be per-
formed.
• If the MIL is flashing while the engine is running,
severe catalytic converter damage and power loss
will soon occur. Immediate service is required.
LOOSE FUEL FILLER CAP MESSAGE
(for versions/markets, where provided)
If the vehicle diagnostic system determines that the
fuel filler cap is loose, improperly installed, or damaged,
a “Check Gascap” message will display in the Electronic
Vehicle Information Center (EVIC). If this occurs,
tighten the fuel filler cap properly and press the TRIP
ODOMETER button to turn off the message. If the
problem continues, the message will appear the next
time the vehicle is started.
A loose, improperly installed, or damaged fuel filler cap
may also turn on the MIL.

NOTE:If the ignition switch is left in the ACC or RUN
(engine not running) position and the transmission is in
PARK, the system will automatically time out after
30 minutes of inactivity and the ignition will switch to
the OFF position.
ENGINE START/STOP Button Functions –
With Driver’s Foot OFF The Brake Pedal
(In PARK Or NEUTRAL Position)
The ENGINE START/STOP button operates similar to
an ignition switch. It has four positions, OFF, ACC,
RUN and START. To change the ignition switch posi-
tions without starting the vehicle and use the accesso-
ries follow these steps.
• Starting with the ignition switch in the OFF position:
• Press the ENGINE START/STOP button once to change the ignition switch to the ACC position,
• Press the ENGINE START/STOP button a second time to change the ignition switch to the RUN
position,
• Press the ENGINE START/STOP button a third time to return the ignition switch to the OFF position.EXTREME COLD WEATHER (BELOW −29°C)
To ensure reliable starting at these temperatures, use
of an externally powered electric engine block heater is
recommended.
IF ENGINE FAILS TO START
WARNING!
• Never pour fuel or other flammable
liqui ds

into the throttle body air inlet
opening in an attempt to start the vehicle. This
could result in a flash fire causing serious per-
sonal injur y.
• Do not attempt to push or tow your vehicle to
get it started. Unburned fuel could enter the
catalytic converter and once the engine has
started, ignite and damage the converter and
vehicle. If the vehicle has a discharged battery,
booster cables may be used to obtain a start from
a booster battery or the battery in another ve-
hicle.This type of start can be dangerous if done
improperly. Refer to “Jump Starting” in “In An
Emergency” for further information.

DESCRIPTIONS
1. Air Bag Warning LightThis light will turn on for four to eight sec-
onds as a bulb check when the ignition switch
is first turned to ON/RUN. If the light is
either not on during starting, stays on, or
turns on while driving, have the system inspected at an
authorized dealer as soon as possible. Refer to “Occu-
pant Restraints” in “Safety” for further information.
2. Malfunction Indicator Light (MIL) The Malfunction Indicator Light (MIL) is part of
an onboard diagnostic system, called OBD, that
monitors engine and transmission control sys-
tems. The light will illuminate when the key is in the
ON/RUN position, before engine start. If the bulb does
not come on when turning the key from OFF to
ON/RUN, have the condition checked promptly. Certain conditions, such as a loose or missing gas cap,
poor fuel quality, etc., may illuminate the MIL after
engine start. The vehicle should be serviced if the MIL
stays on through several of your typical driving cycles.
In most situations, the vehicle will drive normally and
will not require towing.
Prolonged driving with the Malfunction
Indicator Light (MIL) on could cause
damage to the engine control system.
It also could affect fuel economy and driveability.
If the MIL is flashing, severe catalytic converter
damage and power loss will soon occur. Immedi-
ate service is required.
WARNING!
A malfunctioning catalytic converter, as
referenc ed

above, can reach higher tem-
peratures than in normal operating conditions.
This can cause a fire if you drive slowly or park
over flammable substances such as dry plants,
wood, cardboard, etc .This could result in death or
serious injury to the driver, occupants or others.
