2017 FIAT 500L ECU

During cold temperatures, transmission operation may
be modified depending on engine coolant temperature.
Normal operation will resume once the engine tempera-
ture has risen to a suitable level.
Instrument Cluster Messages
Dedicated messages will be displayed in the instrument
cluster to alert the driver when certain unusual condi-
tions occur.
Transmission Limp Home Mode
Transmission function is monitored electronically for
abnormal conditions. If a condition is detected that
could result in transmission damage, Transmission
Limp Home Mode is activated. In this mode, the
transmission remains in third gear regardless of which
forward gear is selected. PARK, REVERSE, and NEU-
TRAL will continue to operate. The Malfunction Indi-
cator Light (MIL) may be illuminated. Limp Home
Mode allows the vehicle to be driven to an authorized
dealer for service without damaging the transmission.
In the event of a momentary problem, the transmission
can be reset to regain all forward gears by performing
the following steps:
1. Stop the vehicle.2. Shift the transmission into PARK.
3. Turn the ignition to the OFF position.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is no
longer detected, the transmission will return to nor-
mal operation.
NOTE: Even if the transmission can be reset, we rec-
ommend that you visit your authorized dealer at your
earliest possible convenience. Your authorized dealer
has diagnostic equipment to determine if the problem
could recur.
If the transmission cannot be reset, authorized dealer
service is required.
AUTOSTICK
AutoStick is a driver-interactive transmission feature
providing manual shift control, giving you more control
of the vehicle. AutoStick allows you to maximize engine
braking, eliminate undesirable upshifts and downshifts,
and improve overall vehicle performance. This system

TOWING A DISABLED VEHICLE
NOTE:This section describes procedures for towing a
disabled vehicle using a commercial towing service.
Towing Condition WheelsOFF The Ground AUTOMATIC TRANSMISSION
Flat Tow NONENOT ALLOWED
Dolly Tow RearNOT ALLOWED
Front OK
Flatbed ALLBEST METHOD
Proper towing or lifting equipment is required to pre-
vent damage to your vehicle. Use only tow bars and
other equipment designed for this purpose, following
equipment manufacturer ’s instructions. Use of safety
chains is mandatory. Attach a tow bar or other towing
device to main structural members of the vehicle, not to
bumpers or associated brackets. State and local laws
regarding vehicles under tow must be observed.
CAUTION!
• Do not use sling-type equipment when towing.
Vehicle damage may occur.

CAUTION! (Continued)
•When securing the vehicle to a flatbed truck, do
not attach to front or rear suspension components.
Damage to your vehicle may result from improper
towing.
If you must use the accessories (wipers, defroster, etc.)
while being towed, the key must be in the ON/RUN
position.
• Vehicle can be towed with the front wheels elevated.
• Vehicle can be towed on a flatbed truck (all wheels off
the ground).

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 transmis-
sion control systems. When these systems are operating
properly, your vehicle will provide excellent perfor-
mance and fuel economy, as well as engine emissions
well within current government regulations.
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.
CAUTION!
•Prolonged driving with the MIL on could cause
further damage to the emission control system. It
could also affect fuel economy and driveability.
The vehicle must be serviced before any emis-
sions tests can be performed.
• If the MIL is flashing while the engine is running,
severe catalytic converter damage and power loss
will soon occur. Immediate service is required.
Onboard Diagnostic System (OBD II)
Cybersecurity
Your vehicle is required to have an Onboard Diagnostic
system (OBD II) and a connection port to allow access to
information related to the performance of your emis-
sions controls. Authorized service technicians may need
to access this information to assist with the diagnosis
and service of your vehicle and emissions system.
300 MAINTAINING YOUR VEHICLE

WARNING!
•ONLY an authorized service technician should
connect equipment to the OBD II connection port
in order to diagnose or service your vehicle.
• If unauthorized equipment is connected to the
OBD II connection port, such as a driver-behavior
tracking device, it may:
• Be possible that vehicle systems, including
safety related systems, could be impaired or a
loss of vehicle control could occur that may
result in an accident involving serious injury or
death.
• Access, or allow others to access, information
stored in your vehicle systems, including per-
sonal information.
For further information, refer to “Cybersecurity” in the
“Understanding Your Instrument Panel” section.
REPLACEMENT PARTS
Use of genuine parts for normal/scheduled mainte-
nance and repairs is highly recommended to ensure the
designed performance. Damage or failures caused by the use of parts which are not quality-equivalent to
genuine parts for maintenance and repairs will not be
covered by the manufacturer ’s warranty.
DEALER SERVICE
Your authorized dealer has the qualified service person-
nel, special tools, and equipment to perform all service
operations in an expert manner. Service Manuals are
available which include detailed service information for
your vehicle. Refer to these Service Manuals before
attempting any procedure yourself.
NOTE:
Intentional tampering with emissions control
systems may void your warranty and could result in
civil penalties being assessed against you.
WARNING!
You can be badly injured working on or around a
motor vehicle. Only do service work for which you
have the knowledge and the proper equipment. If
you have any doubt about your ability to perform a
service job, take your vehicle to a competent me-
chanic.

Be sure to clean the top of the master cylinder area
before removing the cap. If necessary, add fluid to bring
the fluid level up to the requirements described on the
brake fluid reservoir. Fluid level can be expected to fall
as the brake pads wear. The brake fluid level should be
checked when the pads are replaced. However, low
fluid level may be caused by a leak and a checkup may
be needed.
Use only manufacturer’s recommended brake fluid.
Refer to “Fluids, Lubricants, And Genuine Parts” in
“Maintaining Your Vehicle” for further information.
WARNING!
•Use only manufacturer’s recommended brake
fluid. Refer to “Fluids, Lubricants, And Genuine
Parts” in “Maintaining Your Vehicle” for further
information. Using the wrong type of brake fluid
can severely damage your brake system and/or
impair its performance. The proper type of brake
fluid for your vehicle is also identified on the
original factory installed hydraulic master cylin-
der reservoir.
(Continued)
WARNING! (Continued)
•To avoid contamination from foreign matter or
moisture, use only new brake fluid or fluid that
has been in a tightly closed container. Keep the
master cylinder reservoir cap secured at all times.
Brake fluid in a open container absorbs moisture
from the air resulting in a lower boiling point.
This may cause it to boil unexpectedly during
hard or prolonged braking, resulting in sudden
brake failure. This could result in a collision.
• Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts, causing
the brake fluid to catch fire. Brake fluid can also
damage painted and vinyl surfaces, care should
be taken to avoid its contact with these surfaces.
• Do not allow petroleum-based fluid to contami-
nate the brake fluid. Brake seal components could
be damaged, causing partial or complete brake
failure. This could result in a collision.
