wheel torque FIAT 500 ABARTH CABRIO 2017 2.G Owners Manual

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 “Electronic 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).
WARNING!
There may be situations on minor hills with a
loaded vehicle, or while pulling a trailer, when the
system will not activate and slight rolling may
occur. This could cause a collision with another
vehicle or object. Always remember the driver is
responsible for braking the vehicle.
Disabling/Enabling HSA
If you wish to turn the HSA system on or off, it can be
done using the Customer Programmable Features in the
Uconnect Settings. Refer to “Uconnect Settings” in for
further information.

STARTING AND OPERATING 205

Partial Off
This mode is entered by momentarily pressing the ESC
Off switch. This mode is intended for times when a
more spirited driving experience is desired. It is also
intended for driving in deep snow, sand or gravel
conditions, when more wheel spin than ESC would
normally allow is required to gain traction.
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
“Partial 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 instru-
ment cluster. 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.
Therefore, the enhanced vehicle stability offered by
ESC is unavailable. The “Full Off” ESC mode is
intended for off-highway or offroad use only.

2. Locate the round Sealant Bottle release button in therecessed area under the sealant bottle.
3. Push 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 Tire Service Kit housing.
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. Push 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 Tire Service 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.

WHAT TO DO IN EMERGENCIES 257

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