engine FIAT 500C 2017 2.G Service Manual

•Look at the transmission gear position display and
verify that it indicates the PARK position (P).
• With brake pedal released, verify that the gear selec-
tor will not move out of PARK.
REVERSE (R)
This range is for moving the vehicle backward. Shift
into REVERSE only after the vehicle has come to a
complete stop.
NEUTRAL (N)
Use this range when the vehicle is standing for pro-
longed periods with the engine running. The engine
may be started in this range. Apply the parking brake
and shift the transmission into PARK if you must leave
the vehicle.
WARNING!
Do not coast in NEUTRAL and never turn off the
ignition to coast down a hill. These are unsafe
practices that limit your response to changing traf-
fic or road conditions. You might lose control of the
vehicle and have a collision.
CAUTION!
Towing the vehicle, coasting, or driving for any
other reason with the transmission in NEUTRAL
can cause severe transmission damage. Refer to
“Recreational Towing” in “Starting And Operating”
and “Towing A Disabled Vehicle” in “What To Do
In Emergencies” for further information.
DRIVE (D)
This range should be used for most city and highway
driving. It provides the smoothest upshifts and down-
shifts, and the best fuel economy. The transmission
automatically upshifts through all forward gears. The
DRIVE position provides optimum driving characteris-
tics under all normal operating conditions.
When frequent transmission shifting occurs (such as
when operating the vehicle under heavy loading con-
ditions, in hilly terrain, or traveling into strong head
winds), use the AutoStick shift control (refer to
AutoStick in this section for further information) to
select a lower gear. Under these conditions, using a
lower gear will improve performance and extend trans-
mission life by reducing excessive shifting and heat
buildup.
194 STARTING AND OPERATING

If the transmission temperature exceeds normal operat-
ing limits, the transmission controller will expand the
range of torque converter clutch engagement. This is
done to prevent transmission damage due to overheat-
ing.
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.
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.

STARTING AND OPERATING 195

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
can also provide you with more control during passing,
city driving, cold slippery conditions, mountain driv-
ing, and many other situations.
Operation
When the gear selector is in the AutoStick position
(beside the Drive position), it can be moved forward
and rearward. This allows the driver to manually select
the transmission gear being used. Moving the gear
selector forward (-) triggers a downshift, and rearward
(+) an upshift. The current gear is displayed in the
instrument cluster.
NOTE:In AutoStick mode, the transmission will only
shift up or down when the driver moves the gear
selector rearward (+) or forward (-), except as described
below.
• The transmission will automatically upshift when
necessary to prevent engine over-speed. •
The transmission will automatically downshift as the
vehicle slows (to prevent engine lugging) and will
display the current gear.
• The transmission will automatically downshift to
first gear when coming to a stop. After a stop, the
driver should manually upshift (+) the transmission
as the vehicle is accelerated.
• You can start out (from a stop) in first, second, or
third gear. Starting out in second or third gear can be
helpful in snow or icy conditions. To select second or
third gear after the vehicle is brought to a stop, tap
the gear selector rearward (+) once or twice.
• The system will ignore shift commands that would
cause engine lugging or overspeed. An audible beep
will sound if an inappropriate gear is requested.
• Avoid using speed control when AutoStick is en-
gaged because the transmission will not shift auto-
matically.
• Transmission shifting will be more noticeable when
AutoStick is enabled.
• The system may revert to automatic shift mode if a
fault or overheat condition is detected.
196 STARTING AND OPERATING

To disengage AutoStick mode, return the gear selector
to the DRIVE position. You can shift in or out of the
AutoStick position at any time without taking your foot
off the accelerator pedal.
WARNING!
Do not downshift for additional engine braking on
a slippery surface. The drive wheels could lose their
grip and the vehicle could skid, causing a collision
or personal injury.
DRIVING ON SLIPPERY SURFACES
Acceleration
Rapid acceleration on snow covered, wet or other
slippery surfaces may cause the driving wheels to pull
erratically to the right or left. This phenomenon occurs
when there is a difference in the surface traction under
the front (driving) wheels.
WARNING!
Rapid acceleration on slippery surfaces is danger-
ous. Unequal traction can cause sudden pulling of
the front wheels. You could lose control of the
vehicle and possibly have a collision. Accelerate
slowly and carefully whenever there is likely to be
poor traction (ice, snow, wet, mud, loose sand, etc.).
Traction
When driving on wet or slushy roads, it is possible for
a wedge of water to build up between the tire and road
surface. This is hydroplaning and may cause partial or
complete loss of vehicle control and stopping ability. To
reduce this possibility, the following precautions should
be observed:
1. Slow down during rainstorms or when the roads areslushy.
2. Slow down if the road has standing water or puddles.
3. Replace the tires when tread wear indicators first become visible.
5
STARTING AND OPERATING 197

CAUTION!(Continued)
•Determine the condition of the road or the path that
is under water and if there are any obstacles in the
way before driving through the standing water.
• Do not exceed 5 mph (8 km/h) when driving
through standing water. This will minimize wave
effects.
• Driving through standing water may cause dam-
age to your vehicle’s drivetrain components. Al-
ways inspect your vehicle’s fluids (i.e., engine oil,
transmission, axle, etc.) for signs of contamination
(i.e., fluid that is milky or foamy in appearance)
after driving through standing water. Do not
continue to operate the vehicle if any fluid ap-
pears contaminated, as this may result in further
damage. Such damage is not covered by the New
Vehicle Limited Warranty.
•
Getting water inside your vehicle’s engine can
cause it to lock up and stall out, and cause serious
internal damage to the engine. Such damage is not
covered by the New Vehicle Limited Warranty.
POWER STEERING
The electric power steering system will give you good
vehicle response and increased ease of maneuverability
in tight spaces. The system will vary its assist to provide
light efforts while parking and good feel while driving.
If the electric steering system experiences a fault that
prevents it from providing assist, you will still have the
ability to steer the vehicle manually.
WARNING!
Continued operation with reduced or no power
steering assist could pose a safety risk to yourself
and others. Service should be obtained as soon as
possible.
If the Steering icon is flashing, it indicates that the
vehicle needs to be taken to an authorized dealer for
service. It is likely the vehicle has lost power steering
assistance.
If the Steering icon is displayed and the “SERVICE
POWER STEERING” message is displayed on the in-
strument cluster screen, they indicate that extreme
steering maneuvers may have occurred which caused

SPORT MODE
Manual Transmission — If Equipped
The Sport mode increases steering feedback to the
driver with slight increases in effort and throttle pedal-
to-engine response. This driving mode is useful while
driving on twisty roads where more steering precision
is desired in spirited cornering.
1. To activate the Sport mode, push the SPORT button.
Once activated, a SPORT message will be displayed in
the instrument cluster.
2. Momentarily release the accelerator pedal.
3. Press the accelerator pedal again to activate.
Automatic Transmission — If Equipped
The Sport mode increases steering feedback to the
driver with slight increase in effort and changes the
transmission shift schedules for more aggressive shift-
ing. This driving mode is useful while driving on twisty
roads where more steering precision is desired in spir-
ited cornering.
1. To activate the Sport mode, push the SPORT button.
Once activated, a SPORT message will be displayed in
the instrument cluster.
2. Push the SPORT button again to return to the stan-dard driving mode.

202 STARTING AND OPERATING

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), 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 203

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 engine
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 engine 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.
Hill Start Assist (HSA)
The HSA system is designed to assist the driver when
starting a vehicle from a stop on a hill. HSA will
maintain the level of brake pressure the driver applied
for a short period of time after the driver takes his foot
off the brake pedal. If the driver does not apply the
throttle during this short period of time, the system will
release brake pressure and the vehicle will roll down
the hill. The system will release brake pressure in
proportion to the amount of throttle applied as the
vehicle starts to move in the intended direction of
travel.
HSA Activation Criteria
The following criteria must be met in order for HSA to
activate:
•
Vehicle must be stopped.
• Vehicle must be on a 2.5% (manual transmission) or
7% grade or greater (automatic transmission) hill.
5
STARTING AND OPERATING 205

•Gear selection matches vehicle uphill direction (i.e.,
vehicle in NEUTRAL (manual transmission), vehicle
facing uphill is in forward gear; vehicle backing
uphill is in REVERSE gear).
WARNING!
There may be situations on minor hills with a
loaded vehicle, or while pulling a trailer, when the
system will not activate and slight rolling may
occur. This could cause a collision with another
vehicle or object. Always remember the driver is
responsible for braking the vehicle.
Disabling/Enabling HSA
If you wish to turn the HSA system on or off, it can be
done using the Customer Programmable Features in the
Uconnect Settings. Refer to “Uconnect Settings” in for
further information.
Electronic Stability Control (ESC)
The Electronic Stability Control (ESC) system enhances
directional control and stability of the vehicle under
various driving conditions. ESC corrects for oversteer-
ing or understeering of the vehicle by applying the
brake of the appropriate wheel to assist in counteracting the oversteering or understeering condition. Engine
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 understeer 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.
ESC Off Switch (Automatic Transmission)
206 STARTING AND OPERATING

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
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
the enhanced vehicle stability offered by the ESC
system is reduced.
