ignition FIAT 500L 2017 2.G Repair Manual

When the parking brake is applied with the ignition
switch in the MAR (ACC/ON/RUN) position, the
Brake Warning Light in the instrument cluster will
illuminate.
When parking on a hill, it is important to turn the front
wheels toward the curb on a downhill grade and away
from the curb on an uphill grade. The parking brake
should always be applied whenever the driver is not in
the vehicle.
WARNING!
•Never leave children alone in a vehicle, or with
access to an unlocked vehicle.
• Allowing children to be in a vehicle unattended is
dangerous for a number of reasons. A child or
others could be seriously or fatally injured. Chil-
dren should be warned not to touch the parking
brake, brake pedal or the gear selector.
• Do not leave the key fob in or near the vehicle or
in a location accessible to children. A child could
operate power windows, other controls, or move
the vehicle.
• Be sure the parking brake is fully disengaged
before driving; failure to do so can lead to brake
failure and a collision.
• Always fully apply the parking brake when leav-
ing your vehicle, or it may roll and cause damage
or injury.
CAUTION!
If the Brake Warning Light remains on with the
parking brake released, a brake system malfunction

is indicated. Have the brake system serviced by an
authorized dealer immediately.
BRAKE SYSTEM
Your vehicle is equipped with dual hydraulic brake
systems. If either of the two hydraulic systems loses
normal capability, the remaining system will still func-
tion. However, there will be some loss of overall brak-
ing effectiveness. You may notice increased pedal travel
during application, greater pedal force required to slow
or stop, and potential activation of the “Brake System
Warning Light”.
In the event power assist is lost for any reason (i.e.,
repeated brake applications with the engine off), the
brakes will still function. However, the effort required
to brake the vehicle will be much greater than that
required with the power system operating.
ELECTRONIC BRAKE CONTROL SYSTEM
Your vehicle is equipped with a advanced electronic
brake control system that includes the Anti-Lock Brake
System (ABS), Brake Assist System (BAS), Traction
Control System (TCS), Hill Start Assist (HSA), Dynamic Steering Torque (DST), and Electronic Stability Control
(ESC). All systems work together to enhance vehicle
stability and control in various driving conditions and
are commonly referred to as ESC.
Four-Wheel Anti-Lock Brake System (ABS)
The Four-Wheel ABS is designed to aid the driver in
maintaining vehicle control under adverse braking con-
ditions. The system operates with a separate computer
to modulate hydraulic pressure, to prevent wheel
lock-up and to help avoid skidding on slippery sur-
faces.
The system’s pump motor runs during an ABS stop to
provide regulated hydraulic pressure. The pump motor
makes a low humming noise during operation, which is
normal.
The ABS includes an amber ABS Warning Light. When
the light is illuminated, the ABS is not functioning. The
system reverts to standard non-anti-lock brakes. Turn-
ing the ignition Off and On again may reset the ABS if
the fault detected was only momentary.
232 STARTING AND OPERATING

•Oversteer - when the vehicle is turning more than
appropriate for the steering wheel position.
• Understeer - when the vehicle is turning less than
appropriate for the steering wheel position.
WARNING!
•The Electronic Stability Control (ESC) cannot
prevent the natural laws of physics from acting on
the vehicle, nor can it increase the traction af-
forded by prevailing road conditions. ESC cannot
prevent all accidents, including those resulting
from excessive speed in turns, driving on very
slippery surfaces, or hydroplaning. ESC also can-
not prevent collisions resulting from loss of ve-
hicle control due to inappropriate driver input for
the conditions. Only a safe, attentive, and skillful
driver can prevent accidents. The capabilities of
an ESC equipped vehicle must never be exploited
in a reckless or dangerous manner which could
jeopardize the user ’s safety or the safety of others.
• Vehicle modifications, or failure to properly
maintain your vehicle, may change the handling

WARNING! (Continued)
characteristics of your vehicle, and may nega-
tively affect the performance of the ESC system.
Changes to the steering system, suspension, brak-
ing system, tire type and size or wheel size may
adversely affect ESC performance. Improperly
inflated and unevenly worn tires may also de-
grade ESC performance. Any vehicle modifica-
tion or poor vehicle maintenance that reduces the
effectiveness of the ESC system can increase the
risk of loss of vehicle control, vehicle rollover,
personal injury and death.
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
MAR (ACC/ON/RUN) position for four sec-
onds. 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
236 STARTING AND OPERATING

vehicle has been driven several miles (kilometers) at
speeds greater than 30 mph (48 km/h), see your autho-
rized dealer as soon as possible to have the problem
diagnosed 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 momentarily
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 OFF Indicator Light indicates the
Electronic Stability Control (ESC) is partially
off or full off.ESC Operating Modes
The ESC system has two available operating modes.
Full On
This is the normal operating mode for ESC. Whenever
the vehicle is started the system will be in this mode.
This mode should be used for most driving situations.
ESC should only be turned to “Partial Off” for specific
reasons as noted. Refer to “Partial Off” for additional
information.
Partial Off
The “ESC OFF” button is located in the switch bank
above the climate control. To enter the “Partial Off”
mode, momentarily push the “ESC OFF” button and the
“ESC Activation/Malfunction Indicator Light” will il-
luminate. To turn the ESC on again, momentarily push
the “ESC OFF” button and the “ESC Activation/
Malfunction Indicator Light” will turn off. This will
restore the normal “ESC On” mode of operation.

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 and the Tire Pressure Monitoring
Telltale Light 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.
• 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.
• Once you repair or replace the original road tire and
reinstall it on the vehicle in place of the compact
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.

Materials Added To Fuel
Besides using unleaded gasoline with the proper octane
rating, gasolines that contain detergents, corrosion and
stability additives are recommended. Using gasolines
that have these additives will help improve fuel
economy, reduce emissions, and maintain vehicle per-
formance.Designated TOP TIER Detergent
Gasoline contains a higher level of
detergents to further aide in mini-
mizing engine and fuel system de-
posits. When available, the usage of
Top Tier Detergent gasoline is recom-
mended. Visit www.toptiergas.com
for a list of TOP TIER Detergent Gasoline Retailers.
Indiscriminate use of fuel system cleaning agents
should be avoided. Many of these materials intended
for gum and varnish removal may contain active sol-
vents or similar ingredients. These can harm fuel sys-
tem gasket and diaphragm materials.
Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your vehicle’s
performance:
• The use of leaded gasoline is prohibited by Fed-
eral law. Using leaded gasoline can impair engine
performance and damage the emissions control
system.
• An out-of-tune engine or certain fuel or ignition
malfunctions can cause the catalytic converter to
overheat. If you notice a pungent burning odor or
some light smoke, your engine may be out of tune
or malfunctioning and may require immediate
service. Contact your authorized dealer for service
assistance.
• The use of fuel additives, which are now being
sold as octane enhancers, is not recommended.
Most of these products contain high concentra-
tions of methanol. Fuel system damage or vehicle
performance problems resulting from the use of
such fuels or additives is not the responsibility of
the manufacturer and may void or not be covered
under the New Vehicle Limited Warranty.

HAZARD WARNING FLASHERS
The Hazard Warning flasher switch is located on the
instrument panel below the radio.Push the switch to turn on the Hazard Warning
flashers. When the switch is activated, all direc-
tional turn signals will flash on and off to warn oncom-
ing traffic of an emergency. Push the switch a second
time to turn off the Hazard Warning flashers.
Do not use this emergency warning system when the
vehicle is in motion. Use it when your vehicle is
disabled and it is creating a safety hazard for other
motorists.
If it is necessary to leave the vehicle to go for service, the
Hazard Warning flashers will continue to operate with
the ignition key removed and the vehicle locked.
NOTE: With extended use, the Hazard Warning flash-
ers may wear down your battery.
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the
potential for overheating by taking the appropriate
action.
• On the highways — slow down. •
In city traffic — while stopped, place the transmis-
sion in NEUTRAL, but do not increase engine idle
speed.
NOTE: There are steps that you can take to slow down
an impending overheat condition:
• If your air conditioner (A/C) is on, turn it off. The
A/C system adds heat to the engine cooling system
and turning the A/C off can help remove this heat.
• You can also turn the temperature control to maxi-
mum heat, the mode control to floor and the blower
control to high. This allows the heater core to act as a
supplement to the radiator and aids in removing heat
from the engine cooling system.
WARNING!
You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator. If
you see or hear steam coming from under the hood,
do not open the hood until the radiator has had time
to cool. Never try to open a cooling system pressure
cap when the radiator or coolant bottle is hot.
