2015 FIAT 500 ABARTH torque

If the transmission temperature exceeds normal operating
limits, the transmission controller will expand the range of
torque converter clutch engagement. This is done to pre-
vent transmission damage due to overheating.
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 NEUTRAL will continue to operate.
The Malfunction Indicator Light (MIL) may be illuminated.
Limp Home Mode allows the vehicle to be driven to an
authorized dealer for service without damaging the trans-
mission.
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 switch 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 normal
operation.

STARTING AND OPERATING 241

SPORT MODE
Manual Transmission — If Equipped
In Sport mode, the engine is more responsive to the
throttle pedal, and provides more maximum torque by
increasing turbo boost pressure. Steering feedback is
improved, and steering effort is slightly higher. This
driving mode is useful for spirited driving.
1. To activate the Sport mode, press 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.

wheel(s) and engine power is reduced to provide en-
hanced acceleration and stability. A feature of the TCS
system, Brake Limited Differential (BLD), functions simi-
lar 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 or Full Off mode. Refer to “Elec-
tronic 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) grade
hill.
•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).

STARTING AND OPERATING 255

To turn ESC on again, momentarily press the switch
again. This will restore the normal ESC On mode of
operation.
WARNING!
When in “Partial Off” mode, the TCS functionality of
ESC (except for the limited slip feature described in
the TCS section) has been disabled and the “ESC Off
Indicator Light” will be illuminated. When in “Par-
tial Off” mode, the engine power reduction of TCS is
disabled, and the enhanced vehicle stability offered
by the ESC system is reduced.
Full Off
This mode is intended for off-highway or off-road use
only and should not be used on public roadways. In this
mode, all TCS and ESC stability features are turned OFF,
except for the limited slip feature described in the TCS
section. To enter the “Full Off” mode, depress and hold
the ESC OFF switch for five seconds. After five seconds,
the ESC OFF Indicator Light will illuminate, and the
“ESC OFF” message will display in the EVIC. To turn
ESC ON again, momentarily press the ESC OFF switch.
WARNING!
In the ESC “Full Off” mode, the engine torque
reduction and stability features are cancelled. There-
fore, the enhanced vehicle stability offered by ESC is
unavailable. The “Full Off” ESC mode is intended
for off-highway or offroad use only.

WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to ensure
that the wheel is properly mounted to the vehicle. Any
time a wheel has been removed and reinstalled on the
vehicle the lug nuts/bolts should be torqued using a
properly calibrated torque wrench.

Inspect the wheel mounting surface prior to mounting
the tire and remove any corrosion or loose particles.

WHAT TO DO IN EMERGENCIES 319

Tighten the lug nuts/bolts in a star pattern until each
nut/bolt has been tightened twice.
After 25 miles (40 km) check the lug nut/bolt torque to be
sure that all the lug nuts/bolts are properly seated
against the wheel.
WARNING!
To avoid the risk of forcing the vehicle off the jack,
do not tighten the lug nuts fully until the vehicle has
been lowered. Failure to follow this warning may
result in personal injury.
JACKING AND TIRE CHANGING — IF EQUIPPED
WARNING!
•Do not attempt to change a tire on the side of the
vehicle close to moving traffic. Pull far enough off
the road to avoid the danger of being hit when
operating the jack or changing the wheel.

320 WHAT TO DO IN EMERGENCIES

WARNING!
To avoid the risk of forcing the vehicle off the jack,
do not fully tighten the wheel bolts until the vehicle
has been lowered. Failure to follow this warning may
result in personal injury.
7. Install the wheel and wheel bolts with the cone shaped
end of the bolts toward the wheel. Lightly tighten the
bolts. To avoid the risk of forcing the vehicle off the
jack, do not tighten the bolts fully until the vehicle has
been lowered.
8. Lower the vehicle by turning the jack screw to the left.
9. Finish tightening the bolts. Push down on the wrench
while tightening the wheel bolts. Alternate bolts until
each bolt has been tightened twice. Refer to “Torque
Specifications” in this section for proper lug bolt
torque. If you doubt that you have tightened the bolts
correctly, have them checked with a torque wrench by
your authorized dealer or service station.
10. Disassemble the jack and tools and place them in the
bag. Stow it under the driver’s seat and secure the
bag to the floor with the straps attached to the floor
of the vehicle.
11. Check the tire pressure as soon as possible. Correct
the tire pressure as required.
JUMP-STARTING PROCEDURE
If your vehicle has a discharged battery, it can be jump-
started using a set of jumper cables and a battery in
another vehicle or by using a portable battery booster
pack. Jump-starting can be dangerous if done improperly
so please follow the procedures in this section carefully.
