2018 FIAT 500C torque

A feature of the TCS system, Brake Limited Differential
(BLD), 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. Refer to “Electronic
Stability Control (ESC)” in this section for further informa-
tion.
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) 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.102 SAFETY

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 “In Case Of Emergency” for
further information.
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. The DRIVE position
provides optimum driving characteristics under all normal
operating conditions. When frequent transmission shifting occurs (such as when
operating the vehicle under heavy loading conditions, 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.
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. Nor-
mal operation will resume once the engine temperature has
risen to a suitable level.
Instrument Cluster Messages
Dedicated messages will be displayed in the instrument
cluster to alert the driver when certain unusual conditions
occur. 6STARTING AND OPERATING 173

Manual Transmission — If Equipped
Lubricant Selection
Use only the manufacturers recommended transmission
fluid. Refer to “Fluids And Lubricants” in “Technical
Specifications” for further information.
Please see an authorized dealer for service.
Fluid Level Check
Check the fluid level by removing the fill plug. The fluid
level should be between the bottom of the fill hole and a
point not more than 3/16 inch (4.7 mm) below the bottom
of the hole.
Add fluid, if necessary, to maintain the proper level.
Please see an authorized dealer for service.
Frequency Of Fluid Change
Under normal operating conditions, the fluid installed at
the factory will give satisfactory lubrication for the life of
the vehicle. Fluid changes are not necessary unless lubri-
cant has become contaminated with water.
NOTE: If contaminated with water, the fluid should be
changed immediately. Automatic Transmission — If Equipped
Selection Of Lubricant
It is important to use the proper transmission fluid to
ensure optimum transmission performance and life. Use
only the manufacturer’s specified transmission fluid. Refer
to “Fluids And Lubricants” in “Technical Specifications”
for fluid specifications. It is important to maintain the
transmission fluid at the correct level using the recom-
mended fluid.
NOTE: No chemical flushes should be used in any trans-
mission; only the approved lubricant should be used.
CAUTION!Using a transmission fluid other than the manufactur-
er ’s recommended fluid may cause deterioration in
transmission shift quality and/or torque converter
shudder. Refer to “Fluids And Lubricants” in “Techni-
cal Specifications” for fluid specifications.
Special Additives
The manufacturer strongly recommends against using any
special additives in the transmission.254 SERVICING AND MAINTENANCE

BRAKE SYSTEM
Your vehicle is equipped with dual hydraulic brake sys-
tems. If either of the two hydraulic systems loses normal
capability, the remaining system will still function. How-
ever, there will be some loss of overall braking effective-
ness. You may notice increased pedal travel during appli-
cation, greater pedal force required to slow or stop, and
potential activation of the Brake Warning Light.
In the event power assist is lost for any reason (i.e.,
repeated brake applications with the engine OFF) the
brakes will still function. However, the effort required to
brake the vehicle will be much greater than that required
with the power system operating. 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 cali-
brated torque wrench using a high quality six sided (hex)
deep wall socket.

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/bolts fully until the vehicle has
been lowered. Failure to follow this warning may
result in personal injury.Wheel Mounting Surface Torque Patterns286 TECHNICAL SPECIFICATIONS
