engine FIAT 500X 2014 2.G Repair Manual

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 “In Case Of
Emergency” 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, traveling into strong head
winds or while towing a heavy trailer), 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 im-
prove performance and extend transmission life by
reducing excessive shifting and heat buildup. If the transmission temperature exceeds normal operat-
ing limits, the transmission controller may modify the
transmission shift schedule, reduce engine torque,
and/or expand the range of torque converter clutch
engagement. This is done to prevent transmission dam-
age due to overheating.
If the transmission becomes extremely hot, the “Trans-
mission Temperature Warning Light” may illuminate
and the transmission may operate differently until the
transmission cools down.
During cold temperatures, transmission operation may
be modified depending on engine and transmission
temperature as well as vehicle speed. This feature
improves warm up time of the engine and transmission
to achieve maximum efficiency. Engagement of the
torque converter clutch, and shifts into 8th or 9th gear,
are inhibited until the transmission fluid is warm.
Normal operation will resume once the transmission
temperature has risen to a suitable level.
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,
232 STARTING AND OPERATING

and improve overall vehicle performance. This system
can also provide you with more control during passing,
city driving, cold slippery conditions, mountain driv-
ing, trailer towing 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 overspeed.
• 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 or second gear (depending on model) 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 or second gear.
Starting out in second gear can be helpful in snow or
icy conditions. Tap the gear selector forward or
rearward to select the desired gear after the vehicle is
brought to a stop.
• If a requested downshift would cause the engine to
overspeed, that shift will not occur.
• The system will ignore attempts to upshift at too low
of a vehicle speed.
• 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.
To disengage AutoStick mode, return the gear selector
to the DRIVE position. You can shift in or out of the
7
STARTING AND OPERATING 233

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.
Transmission Limp Home Mode
Transmission function is electronically monitored 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 fourth 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. Cycle the ignition to the STOP/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
recommend 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.
234 STARTING AND OPERATING

Ignition Park Interlock
Vehicles Equipped With Keyless Enter-N-Go:
This vehicle is equipped with an Ignition Park Inter-
lock, which requires the transmission to be in PARK
before the ignition can be turned to the STOP/OFF
mode. Also, the transmission is locked in PARK when-
ever the ignition is in the STOP/OFF mode.
Brake/Transmission Shift Interlock System
This vehicle is equipped with a Brake Transmission
Shift Interlock system (BTSI) that holds the transmis-
sion gear selector in PARK unless the brakes are ap-
plied. To shift the transmission out of PARK, the igni-
tion must be cycled to the RUN mode (engine running
or not) and the brake pedal must be pressed.
The brake pedal must also be pressed before pushing
the button on the gear selector to shift from NEUTRAL
into DRIVE or REVERSE when the vehicle is stopped or
moving at low speeds.
SPEED CONTROL — IF EQUIPPED
When engaged, the Speed Control takes over accelera-
tor operations at speeds greater than 25 mph (40 km/h).The Speed Control buttons are located on the right side
of the steering wheel.
NOTE:
In order to ensure proper operation, the Speed
Control System has been designed to shut down if
multiple Speed Control functions are operated at the
same time. If this occurs, the Speed Control System can
be reactivated by pushing the Speed Control on/off
button and resetting the desired vehicle set speed.

Sport Mode –This mode is designed to increase
steering feedback to the driver with a slight increase in
effort and changes the transmission shift schedules for
more aggressive shifting. This driving mode is useful
while driving on twisty roads where more steering
precision is desired in spirited cornering.
Warning Messages
In the event of a system fault, the system automatically
defaults to Automode and a message will appear in
the instrument cluster display.
Refer to “Instrument Cluster Display” in “Getting To
Know Your Instrument Panel” for further information.
BRAKE CONTROL — IF EQUIPPED
Brake Control
The Brake Control system with mitigation provides the
driver with audible warnings, visual warnings (within
the instrument cluster display), and may apply a brake
jerk to warn the driver when it detects a potential
frontal collision. The warnings and limited braking are
intended to provide the driver with enough time to
react, avoid or mitigate the potential collision. NOTE:
•
Brake Control monitors the information from the
forward looking sensors as well as the Electronic
Brake Controller (EBC), to calculate the probability of
a forward collision. When the system determines that
a forward collision is probable, the driver will be
provided with audible and visual warnings and may
provide a brake jerk warning.
• If the driver does not take action based upon these
progressive warnings, then the system will provide a
limited level of active braking to help slow the
vehicle and mitigate the potential forward collision.
If the driver reacts to the warnings by braking and
the system determines that the driver intends to
avoid the collision by braking but has not applied
sufficient brake force, the system will compensate
and provide additional brake force as required.
Vehicles With A Manual Transmission: After the end
of the intervention of automatic braking, the engine
could stall, unless the driver can depress the clutch
pedal.
Vehicles With Automatic Transmission: After the end
of the intervention of automatic braking, the transmis-
sion may remain in last gear stored: therefore the car

a more limited and gradual. This setting gives the
driver the maximum possible time of reaction to pre-
vent a possible accident.
By changing the option toNear, the system will warn
the driver of a possible accident with the vehicle ahead
of it when the latter is a reduced distance. This setting
offers a reaction time to the driver lower than the
settings Medium andFar, in the case of a potential
accident, while a more dynamic driving of the car.
The setting of the sensitivity of the system is maintained
in memory when the engine is switched off.
Brake Control Limited Warning
If the instrument cluster display will read “Brake Con-
trol Limited Functionality” or “Brake Control Limited
Functionality Clean Front Windshield” momentarily,
there may be a condition that limits Brake Control
functionality. Although the vehicle is still drivable un-
der normal conditions, the active braking may not be
fully available. Once the condition that limited the
system performance is no longer present, the system
will return to its full performance state. If the problem
persists, see your authorized dealer.
Service Brake Control Warning
If the system turns off, and the instrument cluster
display displays:
• Brake Control Unavailable Service Required
This indicates there is an internal system fault. Al-
though the vehicle is still drivable under normal con-
ditions, have the system checked by an authorized
dealer.
“Wipe Front Radar Sensor In Front Of Vehicle” Warn-
ing
The “Brake Control Front Radar Sensor Temporarily
Blocked” warning will display when conditions tempo-
rarily limit system performance. This most often occurs
at times of poor visibility, such as in snow or heavy rain.
The system may also become temporarily blinded due
to obstructions, such as mud, dirt or ice. In these cases,
the instrument cluster display will display “Brake Con-
trol Front Radar Sensor Temporarily Blocked” and the
system will deactivate.
The “Brake Control Front Radar Sensor Temporarily
Blocked” message can sometimes be displayed while
driving in highly reflective areas (i.e. tunnels with
reflective tiles, or ice and snow). The system will

FUEL REQUIREMENTS
1.4L Turbo Engine
This engine is designed to meet all
emission regulations and provide
satisfactory fuel economy and per-
formance when using high-quality
unleaded regulargasoline having
an octane rating of 87 using the
(R+M)/2 method. For optimum per-
formance and fuel economy the use of 91 octane or
higher is recommended.
While operating on gasoline with an octane number of
87, hearing a light knocking sound from the engine is
not a cause for concern. However, if the engine is heard
making a heavy knocking sound, see your dealer im-
mediately. Use of gasoline with an octane number lower
than 87 can cause engine failure and may void or not be
covered by the New Vehicle Limited Warranty.
Poor quality gasoline can cause problems such as hard
starting, stalling, and hesitations. If you experience
these symptoms, try another brand of gasoline before
considering service for the vehicle.

STARTING AND OPERATING 261

2.4L Engine
All available gasoline engines are
designed to meet all emissions regu-
lations and provide excellent fuel
economy and performance when us-
ing high quality unleaded “regular”
gasoline having a octane rating of 87
using the (R+M)/2 method. The use
of premium gasoline is not recommended, as it will not
provide any benefit over regular gasoline in these
engines.
While operating on gasoline with an octane number of
87, hearing a light knocking sound from the engine is
not a cause for concern. However, if the engine is heard
making a heavy knocking sound, see your dealer im-
mediately. Use of gasoline with an octane number lower
than 87 can cause engine failure and may void or not be
covered by the New Vehicle Limited Warranty.
Poor quality gasoline can cause problems such as hard
starting, stalling, and hesitations. If you experience
these symptoms, try another brand of gasoline before
considering service for the vehicle.
Reformulated Gasoline
Many areas of the country require the use of cleaner
burning gasoline referred to as “Reformulated Gaso-
line”. Reformulated gasoline contains oxygenates and
are specifically blended to reduce vehicle emissions and
improve air quality.
The use of reformulated gasoline is recommended.
Properly blended reformulated gasoline will provide
improved performance and durability of engine and
fuel system components.
Gasoline/Oxygenate Blends
Some fuel suppliers blend unleaded gasoline with
oxygenates such as ethanol.
CAUTION!
DO NOT use gasoline containing methanol or gaso-
line containing more than 15% ethanol (E-15). Use
of these blends may result in starting and drivabil-
ity problems, damage critical fuel system compo-
nents, cause emissions to exceed the applicable
standard, and/or cause the “Malfunction Indicator

262 STARTING AND OPERATING

CAUTION!(Continued)
Light” to illuminate. Please observe pump labels as
they should clearly communicate if a fuel contains
greater than 15% ethanol (E-15).
Problems that result from using gasoline containing
more than 15% ethanol (E-15) or gasoline containing
methanol are not the responsibility of the manufacturer
and may void or not be covered under New Vehicle
Limited Warranty.
E-85 Usage In Non-Flex Fuel Vehicles
Non-Flex Fuel Vehicles (FFV) are compatible with gaso-
line containing up to 15% ethanol (E-15). Gasoline with
higher ethanol content may void the New Vehicle
Limited Warranty.
If a Non-FFV vehicle is inadvertently fueled with E-85
fuel, the engine will have some or all of these symp-
toms:
• Operate in a lean mode.
• OBD II “Malfunction Indicator Light” on.
• Poor engine performance.
• Poor cold start and cold drivability. •
Increased risk for fuel system component corrosion.
CNG And LP Fuel System Modifications
Modifications that allow the engine to run on com-
pressed natural gas (CNG) or liquid propane (LP) may
result in damage to the engine, emissions, and fuel
system components. Problems that result from running
CNG or LP are not the responsibility of the manufac-
turer and may void or not be covered under the New
Vehicle Limited Warranty.
MMT In Gasoline
Methylcyclopentadienyl Manganese Tricarbonyl
(MMT) is a manganese-containing metallic additive
that is blended into some gasoline to increase octane.
Gasoline blended with MMT provides no performance
advantage beyond gasoline of the same octane number
without MMT. Gasoline blended with MMT reduces
spark plug life and reduces emissions system perfor-
mance in some vehicles. The manufacturer recom-
mends that gasoline without MMT be used in your
vehicle. The MMT content of gasoline may not be
indicated on the gasoline pump, therefore, you should
ask your gasoline retailer whether the gasoline contains
MMT. MMT is prohibited in Federal and California
reformulated gasoline.

STARTING AND OPERATING 263

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.
