engine FIAT 500L 2016 2.G Service Manual

After Starting
The idle speed is controlled automatically and it will
decrease as the engine warms up.
Turbo Charger “Cool Down”
This vehicle is equipped with an after-run pump to cool
the turbocharger after the engine is shut off. Depending
on the type of driving and the amount of cargo, the pump
will run for up to 10 minutes after the engine has been
shut off to circulate coolant through the turbocharger.
Although the pump is rubber-mounted for quiet opera-
tion, it is normal to hear it running during this time.
MANUAL TRANSMISSION — IF EQUIPPED
WARNING!
You or others could be injured if you leave the
vehicle unattended without having the parking
brake fully applied. The parking brake should al-
ways be applied when the driver is not in the vehicle,
especially on an incline.
Fully press the clutch pedal before you shift gears. As you
release the clutch pedal, lightly press the accelerator
pedal.
268 STARTING AND OPERATING

Downshifting
Proper downshifting will improve fuel economy and
prolong engine life.
CAUTION!
If you skip a gear while downshifting or downshift
at too high of a vehicle speed, these conditions may
cause the engine to overspeed if too low of a gear is
selected and the clutch pedal is released. Damage to
the clutch and the transmission can result from
skipping a gear while downshifting or downshifting
at too high of a vehicle speed even if the clutch pedal
is held pressed (i.e., not released).
To maintain a safe speed and prolong brake life, shift
down to second or first when descending a steep grade. When turning a corner, or driving up a steep grade,
downshift early so that the engine will not be overbur-
dened.
AUTOMATIC TRANSMISSION — IF EQUIPPED
CAUTION!
Damage to the transmission may occur if the follow-
ing precautions are not observed:
•
Shift into or out of PARK or REVERSE only after
the vehicle has come to a complete stop.
• Do not shift between PARK, REVERSE, NEU-
TRAL, or DRIVE when the engine is above idle
speed.
• Before shifting into any gear, make sure your foot
is firmly pressing the brake pedal.
270 STARTING AND OPERATING

NOTE:You must press and hold the brake pedal while
shifting out of PARK.
WARNING!
• It is dangerous to shift out of PARK or NEUTRAL
if the engine speed is higher than idle speed. If
your foot is not firmly pressing the brake pedal, the
vehicle could accelerate quickly forward or in re-
verse. You could lose control of the vehicle and hit
someone or something. Only shift into gear when
the engine is idling normally and your foot is
firmly pressing the brake pedal.
• Unintended movement of a vehicle could injure
those in or near the vehicle. As with all vehicles,
you should never exit a vehicle while the engine is
running. Before exiting a vehicle, always apply the
parking brake, shift the automatic transmission

into PARK or the manual transmission into RE-
VERSE, turn the vehicle OFF, remove the Key Fob
from the ignition and lock your vehicle.
• 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. Children 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.

STARTING AND OPERATING 271

Key Ignition Park Interlock
This vehicle is equipped with a Key Ignition Park Inter-
lock which requires the transmission to be in PARK
before the ignition switch can be turned to the LOCK/
OFF (key removal) position. The key can only be re-
moved from the ignition when the ignition is in the
LOCK/OFF position, and once removed, the transmis-
sion is locked in PARK.
Brake/Transmission Shift Interlock System
This vehicle is equipped with a Brake Transmission Shift
Interlock System (BTSI) that holds the shift lever in PARK
unless the brakes are applied. To shift the transmission
out of PARK, the ignition switch must be turned to the
ON/RUN position (engine running or not), and the
brake pedal (and the lock button on the shift lever) must
be pressed.
Six-Speed Euro Twin Clutch Transmission — If
Equipped
The transmission gear position display (located in the
instrument cluster) indicates the transmission gear range.
You must push the brake pedal and the lock button on
the shift lever to move the shift lever out of PARK (refer
to “Brake/Transmission Shift Interlock System” in this
section). To drive, push the lock button on the front of the
shift lever and move the shift lever from PARK or
NEUTRAL to the DRIVE position.
The electronically-controlled transmission provides a
precise shift schedule. The transmission electronics are
self-calibrating; therefore, the first few shifts on a new
vehicle may be somewhat abrupt. This is a normal
condition, and precision shifts will develop within a few
hundred miles (kilometers).
272 STARTING AND OPERATING

NOTE:If the shift lever cannot be moved to the PARK,
REVERSE, or NEUTRAL position (when pushed for-
ward) it is probably in the AutoStick (+/-) position
(beside the DRIVE position). In AutoStick mode, the
transmission gear (1, 2, 3, etc.) is displayed in the
instrument cluster. Move the shift lever to the right (into
the DRIVE [D] position) for access to PARK, REVERSE,
and NEUTRAL.
Gear Ranges
DO NOT race the engine when shifting from PARK or
NEUTRAL into another gear range.
NOTE: After selecting any gear range, wait a moment to
allow the selected gear to engage before accelerating.
This is especially important when the engine is cold. PARK (P)
This range supplements the parking brake by locking the
transmission. The engine can be started in this range.
Never attempt to use PARK while the vehicle is in
motion. Apply the parking brake when leaving the
vehicle in this range.
When parking on a level surface, you may shift the
transmission into PARK first, and then apply the parking
brake.
When parking on a hill, apply the parking brake before
shifting the transmission to PARK, otherwise the load on
the transmission locking mechanism may make it diffi-
cult to move the shift lever out of PARK. As an added
precaution, turn the front wheels toward the curb on a
downhill grade and away from the curb on an uphill
grade.
274 STARTING AND OPERATING

WARNING!
•Never use the PARK position as a substitute for the
parking brake. Always apply the parking brake
fully when parked to guard against vehicle move-
ment and possible injury or damage.
• Your vehicle could move and injure you and others
if it is not in PARK. Check by trying to move the
gear selector/shift lever out of PARK with the brake
pedal released. Make sure the transmission is in
PARK before leaving the vehicle.
• It is dangerous to shift out of PARK or NEUTRAL
if the engine speed is higher than idle speed. If
your foot is not firmly pressing the brake pedal, the
vehicle could accelerate quickly forward or in re-
verse. You could lose control of the vehicle and hit
someone or something. Only shift into gear when
the engine is idling normally and your foot is
firmly pressing the brake pedal.

WARNING! (Continued)
•Unintended movement of a vehicle could injure
those in or near the vehicle. As with all vehicles,
you should never exit a vehicle while the engine is
running. Before exiting a vehicle, always shift an
automatic transmission into PARK, or a manual
transmission into FIRST gear or REVERSE, turn
the engine OFF, apply the parking brake, and
remove the ignition key. When the ignition is in the
LOCK/OFF (key removal) position, an automatic
transmission is locked in PARK, securing the ve-
hicle against unwanted movement.
• When leaving the vehicle, always remove the igni-
tion key from the vehicle and lock the vehicle.
• 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. Children should be
warned not to touch the parking brake, brake pedal
or the gear selector.
• Do not leave the ignition key in or near the vehicle
(or in a location accessible to children). A child
could operate power windows, other controls, or
move the vehicle.
CAUTION!
• Before moving the shift lever out of PARK, you
must turn the ignition switch from the LOCK/OFF
position to the ON/RUN position, and also press
the brake pedal. Otherwise, damage to the shift
lever could result.
(Continued)
CAUTION! (Continued)
•DO NOT race the engine when shifting from
PARK or NEUTRAL into another gear range, as this
can damage the drivetrain.
The following indicators should be used to ensure that
you have engaged the transmission into the PARK posi-
tion:
• When shifting into PARK, push the lock button on the
shift lever and firmly move the lever all the way
forward until it stops and is fully seated.
• Look at the transmission gear position display and
verify that it indicates the PARK position (P).
• With brake pedal released, verify that the shift lever
will not move out of PARK.
276 STARTING AND OPERATING

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 prolonged
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 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. 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.
To maximize fuel economy, the Euro Twin Clutch Six
Speed Transmission uses a geartrain arrangement similar
5
STARTING AND OPERATING 277

to a manual transmission. Therefore, you should become
familiar with some of the normal operational character-
istics of this transmission:
•During low-speed driving conditions in first gear,
vehicle momentum changes may feel exaggerated in
response to changes in accelerator pedal position. This
behavior is normal and is similar to vehicles equipped
with a manual transmission.
• At low speeds you may hear mechanical noises similar
to a manual transmission as the transmission changes
gears. These noises are normal and will not damage
the transmission.
• Very aggressive driving may result in some clutch
odor similar to a manual transmission. An active
warning message will display in the Instrument Clus-
ter if cool down actions are needed. •
When stopped on an incline, always use the brakes to
hold the vehicle in place. On steep inclines, Hill Start
Assist (HSA) will temporarily hold the vehicle in
position when the brake pedal is released. If the
accelerator pedal is not applied after a short time, the
vehicle will roll back. Either reapply the brake (to hold
the vehicle) or press the accelerator to climb the hill.
• Before and after the engine is started, you may hear a
hydraulic pump for a short period of time. This noise
is normal and will not damage the transmission.
When frequent transmission shifting occurs (such as
when operating the vehicle under heavy loading condi-
tions, 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 transmission
life by reducing excessive shifting and heat buildup.
278 STARTING AND OPERATING

During extremely cold temperatures, the transmission
will not operate if the oil temperature is -22°F (-30°C) or
below. Allow the engine to idle briefly with the transmis-
sion in PARK in order to warm the fluid. Normal
operation will resume once the transmission temperature
has risen to a suitable level.Instrument Cluster Messages
Messages will be displayed in the instrument cluster to
alert the driver when certain unusual conditions occur.
These messages are described below.
MESSAGE
DESCRIPTION
GEAR UNAVAILABLE In AutoStick mode, the gear selected by the driver is
