2014 FIAT 500 ABARTH wheel torque

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 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 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)
grade hill.
•Gear selection matches vehicle uphill direction (i.e.,
vehicle in NEUTRAL (manual transmission), vehicle

(F) Sealant Bottle And Hose Replacement:
1. Uncoil the Sealant Hose (6) (clear in color).
2. Locate the round Sealant Bottle release button in the
recessed area under the sealant bottle.
3. Press the Sealant Bottle release button. The Sealant
Bottle (1) will pop up. Remove the bottle and dispose
of it accordingly.
4. Clean any remaining sealant from the TIREFIT hous-
ing.
5. Position the new Sealant Bottle (1) in the housing so
that the Sealant Hose (6) aligns with the hose slot in
the front of the housing. Press the bottle into the
housing. An audible click will be heard indicating the
bottle is locked into place.
6. Verify that the cap is installed on the fitting at the end
of the Sealant Hose (6) and return the hose to its
storage area (located on the bottom of the air pump).
7. Return the TIREFIT kit to its storage location in the
vehicle.
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.

Wheel Mounting Surface
292 WHAT TO DO IN EMERGENCIES

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.

WARNING!
Raising the vehicle higher than necessary can make
the vehicle less stable. It could slip off the jack and
hurt someone near it. Raise the vehicle only enough
to remove the tire.
4. Using the swivel wrench, raise the vehicle by turning
the jack screw to the right. Raise the vehicle only until
the tire just clears the surface and enough clearance is
obtained. Minimum tire lift provides maximum stabil-
ity.
5. Remove the wheel bolts and pull the wheel off the
hub. For vehicles equipped with aluminum wheels,
the center caps must be removed to remove the wheel
bolts.
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.
6. 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.
7. Lower the vehicle by turning the jack screw to the left.
8. 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
