2017 FIAT 500E Owners Manual

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
In the event regenerative braking or power assist is lost
for any reason the brakes will still function. The effort
required to brake the vehicle will be significantly more
than that required with the power system operating.
If either the front or rear hydraulic system loses normal
capability, the remaining system will still function with
some loss of braking effectiveness. This will be evident
by increased pedal travel during application, greater
pedal force required to slow or stop, and activation of
the Brake Warning Light and the ABS Warning Light
during brake use.
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), TractionControl System (TCS), 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.

STARTING AND OPERATING 183

WARNING!
•Pumping the Anti-Lock Brakes will diminish
their effectiveness and may lead to a collision.
Pumping makes the stopping distance longer. Just
press firmly on your brake pedal when you need
to slow down or stop.
• The Anti-Lock Brake System (ABS) cannot pre-
vent the natural laws of physics from acting on
the vehicle, nor can it increase braking or steering
efficiency beyond that afforded by the condition
of the vehicle brakes and tires or the traction
afforded.
• The ABS cannot prevent collisions, including
those resulting from excessive speed in turns,
following another vehicle too closely, or hydro-
planing.
• The capabilities of an ABS-equipped vehicle
must never be exploited in a reckless or danger-
ous manner, which could jeopardize the user’s
safety or the safety of others.
When you are in a severe braking condition involving
the use of the ABS, you will experience some pedal drop
as the vehicle comes to a stop. This is the result of the
system reverting to the base brake system. Engagement of the ABS may be accompanied by a
pulsing sensation. You may also hear a clicking noise.
These occurrences are normal and indicate that the
system is functioning properly.
Brake Assist System (BAS)
The BAS is designed to optimize the vehicle’s braking
capability during emergency braking maneuvers. The
system detects an emergency braking situation by sens-
ing the rate and amount of brake application and then
applies optimum pressure to the brakes. This can help
reduce braking distances. The BAS complements the
Anti-Lock Brake System (ABS). Applying the brakes
very quickly results in the best BAS assistance. To
receive the benefit of the system, you must apply
continuous
braking pressure during the stopping se-
quence (do not “pump” the brakes). Do not reduce
brake pedal pressure unless braking is no longer de-
sired. Once the brake pedal is released, the BAS is
deactivated.
184 STARTING AND OPERATING

WARNING!
•The Brake Assist System (BAS) cannot prevent
the natural laws of physics from acting on the
vehicle, nor can it increase the traction afforded
by prevailing road conditions.
• The BAS cannot prevent collisions, including
those resulting from excessive speed in turns,
driving on very slippery surfaces, or hydroplan-
ing.
• The capabilities of a BAS-equipped vehicle must
never be exploited in a reckless or dangerous
manner which could jeopardize the user ’s safety
or the safety of others.
Traction Control System (TCS)
This system monitors the amount of wheel spin of each
of the driven wheels. If wheel spin is detected, brake
pressure is applied to the slipping wheel(s) and vehicle
power is reduced to provide enhanced acceleration and
stability. A feature of the TCS system, Brake Limited
Differential (BLD), functions similar to a limited slip
differential and controls the wheel spin across a driven
axle. If one wheel on a driven axle is spinning faster
than the other, the system will apply the brake of the spinning wheel. This will allow more torque to be
applied to the wheel that is not spinning. This feature
remains active even if TCS and ESC are in the Partial
Off mode. Refer to “Electronic Stability Control (ESC)”
in this section for further information.
Electronic Stability Control (ESC)
This system enhances directional control and stability of
the vehicle under various driving conditions. ESC cor-
rects for oversteering or understeering of the vehicle by
applying the brake of the appropriate wheel to assist in
counteracting the oversteering or understeering condi-
tion. Vehicle power may also be reduced to help the
vehicle maintain the desired path. ESC uses sensors in
the vehicle to determine the vehicle path intended by
the driver and compares it to the actual path of the
vehicle. When the actual path does not match the
intended path, ESC applies the brake of the appropriate
wheel to assist in counteracting the oversteer or under-
steer condition.
•
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.5
STARTING AND OPERATING 185

NOTE:The ESC Off switch is located on the instrument
panel.
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
characteristics of your vehicle, and may nega-
tively affect the performance of the ESC system.
(Continued)
WARNING! (Continued)
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 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 ESC system will be in On
mode. This mode should be used for most driving
situations. ESC should only be turned to Partial Off for
specific reasons as noted below.
Partial Off
This mode is entered by momentarily pushing the ESC
Off switch. This mode is intended to be used if the
186 STARTING AND OPERATING

vehicle is in deep snow, sand or gravel conditions and
more wheel spin than ESC would normally allow is
required to gain traction.
To turn ESC on again, momentarily pushing the switch
again. This will restore the normal ESC On mode of
operation.
NOTE:To improve the vehicle’s traction when driving
with snow chains, or starting off in deep snow, sand or
gravel, it may be desirable to switch to the Partial Off
mode by pushing the switch. Once the situation requir-
ing ESC to be switched to the Partial Off mode is
overcome, turn ESC back on by momentarily pushing
the switch. This may be done while the vehicle is in
motion.
WARNING!
• When in “Partial Off” mode, the TCS functional-
ity of ESC, (except for the limited slip feature
described in the TCS section), has been disabled
and the “ESC Off Indicator Light” will be illumi-
nated. When in “Partial Off” mode, the engine
power reduction feature of TCS is disabled, and
(Continued)
WARNING! (Continued)
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
MAR (ACC/ON/RUN) position for four sec-
onds. If the ESC Activation/Malfunction Indicator
Light comes on continuously with the vehicle operating
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 miles
(kilometers) at speeds greater than 30 mph (48 km/h),
see your authorized 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/5
STARTING AND OPERATING 187

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.Regenerative Braking System (RBS)
Your 500e has a Regenerative Braking System
(RBS). The RBS reduces the high voltage
battery consumption of the vehicle, particu-
larly in stop-and-go city traffic. The electric
motors which propel the vehicle forward can operate as
generators when braking. The RBS recharges the high
voltage battery under certain braking conditions by
recapturing energy that would otherwise be lost while
braking. The electric power that is generated goes back
into the high voltage battery for later use, for example
when acceleration is desired.
The RBS uses conventional hydraulic friction brakes,
regenerative braking, or a combination to slow the
vehicle. If the system detects slippery conditions while
braking, ONLY friction is used to slow the vehicle. The
RBS can result in extended life of the hydraulic service
brakes; however, all inspection, scheduled mainte-
nance, and service intervals for the vehicle service
brakes must be followed.
