light FIAT 500X 2022 Service Manual

84STARTING AND OPERATING
In the unlikely event of a malfunction of the EPB
system, a yellow EPB fault lamp will illuminate. This
may be accompanied by the Brake Warning Light
flashing. In this status, some EPB functionalities
may be deactivated. In this event, urgent service of
the EPB system is required. Do not rely on the EPB
to hold the vehicle stationary.
AUTO PARK BRAKE
The EPB can be programmed to be applied
automatically whenever the vehicle speed is below
1.9 mph (3 km/h) and the automatic transmission
is placed in PARK whenever the ignition is in the
OFF position. Auto Park Brake is enabled and
disabled by customer selection through the
Customer Programmable Features section of the
Uconnect Settings.
Any single Auto Park Brake application can be
bypassed by pushing the EPB switch to the release
position while the transmission is placed in PARK
and the ignition is in the RUN position. In some cases, if the ignition is cycled from ON/RUN to OFF
and the gear selector is not firmly locked in the
PARK position, EPB applies automatically even if
Auto Park Brake has been previously disabled.
SAFEHOLD
SafeHold is a safety feature of the EPB system that
will engage the parking brake automatically if the
vehicle is left unsecured while the ignition switch is
in the RUN position.
The EPB will automatically engage if all of the
following conditions are met:
Vehicle speed is below 1.9 mph (3 km/h).
There is no attempt to press the brake pedal or
accelerator pedal.
The seat belt is unbuckled.
The driver door is open.
The vehicle is not in the PARK position.
SafeHold can be temporarily bypassed by pushing
the EPB switch while the driver door is open and
the brake pedal is pressed. Once manually
bypassed, SafeHold will be enabled again once the
vehicle reaches 12 mph (20 km/h) or the ignition
is cycled to the OFF position and back to RUN
position.
BRAKE SERVICE MODE
We recommend having your brakes serviced by an
authorized dealer. You should only make repairs
for which you have the knowledge and the right
equipment. You should only enter Brake Service
Mode during brake service.
When servicing your rear brakes, it may be
necessary for you or your technician to push the
rear piston into the rear caliper bore. With the EPB
system, this can only be done after retracting the
EPB actuator. The actuator retraction can be done
easily by entering the Brake Service Mode. This
menu based system will guide you through the
steps necessary to retract the EPB actuator in
order to perform rear brake service.
Service Mode has requirements that must be met
in order to be activated:
The vehicle must be at a standstill.
The parking brake must be disabled.
The transmission must be in PARK or NEUTRAL.
The EPB switch not activated.
The ignition is in the ON/RUN position.
The brake pedal not pressed.
While in service mode, the EPB fault lamp will flash
continuously while the ignition is placed in the ON
position.
WARNING!
Driving the vehicle with the parking brake
engaged, or repeated use of the parking brake
to slow the vehicle may cause serious damage to
the brake system. Be sure the parking brake is
fully disengaged before driving; failure to do so
can lead to brake failure and a collision.

88STARTING AND OPERATING
DRIVE (D)
This range should be used for most city and
highway driving. It provides the smoothest upshifts
and downshifts, and the best fuel economy. The
transmission automatically upshifts through all
forward gears.
When frequent transmission shifting occurs (such
as when operating the vehicle under heavy loading
conditions, in hilly terrain, traveling into strong
head winds or while towing a heavy trailer), use the
AutoStick shift control to select a lower gear. Under
these conditions, using a lower gear will improve performance and extend transmission life by
reducing excessive shifting and heat buildup.
If the transmission temperature exceeds normal
operating 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 damage due to overheating.
If the transmission becomes extremely hot, the
Transmission 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 EIGHTH or NINTH 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, and improve overall
vehicle performance. This system can also provide you with more control during passing, city driving,
cold slippery conditions, mountain driving, 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
lower and higher 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.
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
traffic 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.

For Towing A Disabled Vehicle Ú page 232.

22_FD_OM_EN_USC_t.book Page 88

STARTING AND OPERATING89
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 Cruise Control when AutoStick is
engaged because the transmission will not shift
automatically.
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 AutoStick position at any time without
taking your foot off the accelerator pedal.
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 may operate only in a fixed
gear, or may remain in NEUTRAL. The Malfunction
Indicator Light (MIL) may be illuminated. Limp
Home Mode may allow 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 OFF.
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 normal operation.
NOTE:Even if the transmission can be reset, we
recommend that you visit an authorized dealer at
your earliest possible convenience. An authorized
dealer has diagnostic equipment to assess the
condition of your transmission. If the transmission
cannot be reset, authorized dealer service is
required.
IGNITION PARK INTERLOCK
This vehicle is equipped with an Ignition Park
Interlock, which requires the transmission to be in
PARK before the ignition can be turned to the OFF
position. Also, the transmission is locked in PARK
whenever the ignition is in the OFF position.
BRAKE TRANSMISSION SHIFT
I
NTERLOCK (BTSI) SYSTEM
This vehicle is equipped with a BTSI that holds the
transmission gear selector in PARK unless the
brakes are applied. To shift the transmission out of
PARK, the ignition must be in the RUN position
(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.
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.

90STARTING AND OPERATING
ALL-WHEEL DRIVE (AWD) — IF EQUIPPED
This feature provides on-demand All-Wheel Drive
(AWD). The system is automatic with no driver
inputs or additional driving skills required. Under
normal driving conditions, the front wheels provide
most of the traction. If the front wheels begin to
lose traction, power is shifted automatically to the
rear wheels. The greater the front wheel traction
loss, the greater the power transfer to the rear
wheels.
Additionally, on dry pavement under heavy throttle
input (where one may have no wheel spin), torque
will be sent to the rear in a preemptive effort to
improve vehicle launch and performance
characteristics.
DYNAMIC SELECTOR — IF EQUIPPED
The Dynamic Selector combines the capabilities of
the vehicle control systems, along with driver input,
to provide the best performance in all driving
conditions.
Dynamic Selector Switch

The Dynamic Selector consists of the following
positions:
Auto Mode – This mode is designed for comfort
and safety in normal driving conditions. In versions
equipped with All-Wheel Drive, this mode also
reduces fuel consumption by automatically
altering the distribution of torque between the
front and rear axle.
All Weather Mode – This mode offers increased
traction control and stability control for low traction
conditions such as driving on a dirt road or off-road
as well as wet and slippery roads.
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 “Auto” mode and a
message will appear in the instrument cluster
display.
For further information Ú
page 64.
ELECTRIC POWER STEERING
The electric power steering system will provide
increased vehicle response and ease of
maneuverability. The power steering system
adapts to different driving conditions.
If the “SERVICE POWER STEERING” OR “POWER
STEERING ASSIST OFF - SERVICE SYSTEM”
message and a steering wheel icon are displayed
on the instrument cluster screen, it indicates that
the vehicle needs to be taken to the dealer for
service. It is likely the vehicle has lost power
steering assistance Úpage 64.
CAUTION!
All wheels must have the same size and type
tires. Unequal tire sizes must not be used.
Unequal tire size may cause failure of the power
transfer unit.
WARNING!
Continued operation with reduced assist could
pose a safety risk to yourself and others. Service
should be obtained as soon as possible.

22_FD_OM_EN_USC_t.book Page 92

STARTING AND OPERATING93
CRUISE CONTROL SYSTEMS — IF EQUIPPED
Your vehicle may be equipped with the Cruise
Control system, or the Adaptive Cruise Control
(ACC) system:
Cruise Control will keep your vehicle at a
constant preset speed.
Adaptive Cruise Control (ACC) will adjust the
vehicle speed up to the preset speed to main -
tain a distance with the vehicle ahead.
NOTE:
In vehicles equipped with ACC, if ACC is not
enabled, Fixed Speed Cruise Control will not
detect vehicles directly ahead of you. Always be
aware of the feature selected.
Only one Cruise Control feature can operate at a
time. For example, if Fixed Speed Cruise Control
is enabled, Adaptive Cruise Control will be
unavailable, and vice versa.
CRUISE CONTROL
When engaged, the Cruise Control takes over
accelerator operations at speeds greater than
20 mph (32 km/h).
The Cruise Control buttons are located on the right
side of the steering wheel.
Cruise Control Buttons

To Activate
Push the on/off button to activate the Cruise
Control. The cruise indicator light in the instrument
cluster display will illuminate. To turn the system
off, push the on/off button a second time. The
cruise indicator light will turn off. The system
should be turned off when not in use.
To Set A Desired Speed
Turn the Cruise Control on. When the vehicle has
reached the desired speed, push the SET (+) or
SET (-) button and release. Release the accelerator
and the vehicle will operate at the selected speed.
A cruise indicator light, along with set speed will
also appear and stay on in the instrument cluster
when the speed is set.
1 — SET (+)/Accel
2 — CANC/Cancel
3 — SET (-)/Decel
4 — On/Off
5 — RES/ResumeWARNING!
Cruise Control can be dangerous where the
system cannot maintain a constant speed. Your
vehicle could go too fast for the conditions, and
you could lose control and have an accident. Do
not use Cruise Control in heavy traffic or on
roads that are winding, icy, snow-covered or
slippery.
WARNING!
Leaving the Cruise Control system on when not
in use is dangerous. You could accidentally set
the system or cause it to go faster than you
want. You could lose control and have an
accident. Always ensure the system is off when
you are not using it.4

22_FD_OM_EN_USC_t.book Page 93

94STARTING AND OPERATING
To Vary The Speed Setting
To Increase Or Decrease The Set Speed
When the Cruise Control is set, you can increase
speed by pushing the SET (+) button, or decrease
speed by pushing the SET (-) button.
U.S. Speed (mph)
Pushing the SET (+) , or SET (-) button once will
result in a 1 mph speed adjustment. Each
subsequent tap of the button results in an
adjustment of 1 mph.
If the button is continually pushed, the set
speed will continue to adjust until the button is
released, then the new set speed will be estab -
lished.
Metric Speed (km/h)
Pushing the SET (+), or SET (-) button once will
result in a 1 km/h speed adjustment. Each
subsequent tap of the button results in an
adjustment of 1 km/h.
If the button is continually pushed, the set
speed will continue to adjust until the button is
released, then the new set speed will be estab -
lished.
To Accelerate For Passing
While the Cruise Control is set, press the
accelerator to pass as you would normally. When
the pedal is released, the vehicle will return to the
set speed.
USING CRUISE CONTROL ON HILLS
The transmission may downshift on hills to
maintain the vehicle set speed.
The Cruise Control system maintains speed up and
down hills. A slight speed change on moderate hills
is normal. On steep hills, a greater speed loss or
gain may occur so it may be preferable to drive
without Cruise Control.
To Resume Speed
To resume a previously set speed, push the RES
button and release. Resume can be used at any
speed above 20 mph (32 km/h).
Deactivation
A tap on the brake pedal, pushing the CANC button,
ESC intervention, brake control mitigation,
Electronic Park Brake intervention, or normal
brake pressure while slowing the vehicle will
deactivate the Cruise Control without erasing the
set speed from memory.
Pushing the on/off button or placing the ignition in
the OFF position erases the set speed from
memory.
ADAPTIVE CRUISE CONTROL (ACC)
Adaptive Cruise Control (ACC) increases the driving
convenience provided by Cruise Control while
traveling on highways and major roadways.
However, it is not a safety system and not designed
to prevent collisions. Cruise Control function
performs differently if your vehicle is not equipped
with ACC Ú page 93.
ACC will allow you to keep Cruise Control engaged
in light to moderate traffic conditions without the
constant need to reset your speed. ACC utilizes a
radar sensor and a forward facing camera
designed to detect a vehicle directly ahead of you
to maintain a set speed.
WARNING!
Cruise Control can be dangerous where the
system cannot maintain a constant speed. Your
vehicle could go too fast for the conditions, and
you could lose control and have an accident. Do
not use Cruise Control in heavy traffic or on
roads that are winding, icy, snow-covered or
slippery.

22_FD_OM_EN_USC_t.book Page 94

98STARTING AND OPERATING
To Vary The Speed Setting
To Increase Or Decrease The Set Speed
After setting a speed, you can increase the set
speed by pushing the SET (+) button, or decrease
speed by pushing the SET (-) button.
U.S. Speed (mph)
Pushing the SET (+) , or SET (-) button once will
result in a 1 mph speed adjustment. Each
subsequent tap of the button results in an
adjustment of 1 mph.
If the button is continually pushed, the set
speed will continue to adjust in 5 mph incre -
ments until the button is released. The new set
speed is reflected in the instrument cluster
display.
Metric Speed (km/h)
Pushing the SET (+) , or SET (-) button once will
result in a 1 km/h speed adjustment. Each
subsequent tap of the button results in an
adjustment of 1 km/h.
If the button is continually pushed, the set
speed will continue to adjust in 10 km/h incre -
ments until the button is released. The new set
speed is reflected in the instrument cluster
display.
NOTE:When you override and push the SET (+) button or
SET (-) button, the new set speed will be the current
speed of the vehicle.
When ACC Is Active:
When you use the SET (-) button to decelerate, if
the engine’s braking power does not slow the
vehicle sufficiently to reach the set speed, the
brake system will automatically slow the
vehicle.
The ACC system maintains set speed when
driving uphill and downhill. However, a slight
speed change on moderate hills is normal. In
addition, downshifting may occur while climbing
uphill or descending downhill. This is normal
operation and necessary to maintain set speed.
When driving uphill and downhill, the ACC
system will cancel if the braking temperature
exceeds normal range (overheated).
If Sport mode is chosen on the Dynamic
Selector, the ACC system will switch to Sport
mode. The system will become more reactive in
case of acceleration.
Setting The Following Distance In ACC
The specified following distance for ACC can be set
by varying the distance setting between four bars
(longest), three bars (long), two bars (medium) and
one bar (short). Using this distance setting and the
vehicle speed, ACC calculates and sets the
distance to the vehicle ahead. This distance
setting will show in the instrument cluster display.

Distance Settings

1 — Longest Distance Setting (Four Bars)
2 — Medium Distance Setting (Two Bars)
3 — Long Distance Setting (Three Bars)
4 — Short Distance Setting (One Bar)

22_FD_OM_EN_USC_t.book Page 98

STARTING AND OPERATING99
To increase the distance setting, push the
Distance Increase button and release. Each time
the button is pushed, the distance setting
increases by one bar (longer).
If there is no vehicle ahead, the vehicle will
maintain the set speed. If a slower moving vehicle
is detected in the same lane, the instrument
cluster display will show the ACC Set With Target
Detected Light. The system adjusts vehicle speed
automatically to maintain the distance setting,
regardless of the set speed.
The vehicle will then maintain the set distance
until:
The vehicle ahead accelerates to a speed above
the set speed.
The vehicle ahead moves out of your lane or
view of the sensor.
The distance setting is changed.
The system disengages Ú page 96.
The maximum braking applied by ACC is limited;
however, the driver can always apply the brakes
manually, if necessary.
NOTE:The brake lights will illuminate whenever the ACC
system applies the brakes. A Proximity Warning will alert the driver if ACC
predicts that its maximum braking level is not
sufficient to maintain the set distance. If this
occurs, a visual alert “BRAKE!” will appear in the
instrument cluster display and a chime will sound
while ACC continues to apply its maximum braking
capacity.
NOTE:The “BRAKE!” screen in the instrument cluster
display is a warning for the driver to take action
and does not necessarily mean that the Full Brake
Control system is applying the brakes autono
-
mously.
Overtake Aid
When driving with ACC engaged and following a
vehicle, the system will provide an additional
acceleration up to the ACC set speed to assist in
passing the vehicle. This additional acceleration is
triggered when the driver utilizes the left turn
signal and will only be active when passing on the
left hand side.
Display Warnings And Maintenance
“FRONT RADAR SENSOR TEMPORARILY
BLOCKED” WARNING
The “ACC Front Radar Sensor Temporarily
Blocked” warning will display and a chime will
sound when conditions temporarily limit system
performance.
This most often occurs at times of poor visibility,
such as in snow or heavy rain. The ACC system may
also become temporarily blinded due to
obstructions, such as mud, dirt or ice. In these
cases, the instrument cluster display will read
“ACC/FCW Unavailable Wipe Front Radar Sensor”
and the system will deactivate.
The “ACC Front Radar Sensor Temporarily
Blocked” message can sometimes be displayed
while driving in highly reflective areas (i.e. ice and
snow, or tunnels with reflective tiles). The ACC
system will recover after the vehicle has left these
areas. Under rare conditions, when the radar is not
tracking any vehicles or objects in its path this
warning may temporarily occur.
