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, Brake Lim-
ited 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 Con-
trol (ESC)” for further information.
ELECTRONIC ROLL MITIGATION (ERM)
This system anticipates the potential for wheel lift by
monitoring the driver’s steering wheel input and the
speed of the vehicle. When ERM determines that the
rate of change of the steering wheel angle and vehicle's
speed are sufficient to potentially cause wheel lift, it
then applies the appropriate brake and may also reduce
engine power to lessen the chance that wheel lift will
occur. ERM will only intervene during very severe or
evasive driving maneuvers. ERM can only reduce the
chance of wheel lift occurring during severe or evasive
driving maneuvers. It cannot prevent wheel lift due toother factors, such as road conditions, leaving the
roadway, or striking objects or other vehicles.
WARNING!
Many factors, such as vehicle loading,
road c on

ditions, and driving conditions,
influence the chance that wheel lift or rollover
may occur. ERM cannot prevent all wheel lift or
rollovers, especially those that involve leaving the
roadway or striking objects or other vehicles.The
capabilities of an ERM-equipped vehicle must
never be exploited in a reckless or dangerous
manner, which could jeopardize the user's safety
or the safety of others.
ELECTRONIC STABILITY CONTROL (ESC)
This system enhances directional control and stability
of the vehicle under various driving conditions. ESC
corrects for over-steering and under-steering the ve-
hicle by applying the brake of the appropriate wheel.
Engine power may also be reduced to help the vehicle
maintain the desired path.
The ESC uses sensors in the vehicle to determine the
path that the driver intends to steer the vehicle and
compares it to the actual path of the vehicle. When the
actual path does not match the intended path, the ESC

• If a requested downshift would cause the engine toover-speed, that shift will not occur.
• Avoid using speed control when AutoStick is en- gaged.
• Transmission shifting will be more noticeable when AutoStick is engaged.
• The system may revert to automatic shift mode if a fault or overheat condition is detected.
To disengage AutoStick mode, return the shift lever to
the DRIVE position. You can shift in or out of the
AutoStick position at any time without taking your foot
off the accelerator pedal.
WARNING!
Do not downshift for additional engine
brakin g

on a slippery surface. The drive
wheels could lose their grip and the vehicle could
skid, causing a collision or personal injury.
ALL WHEEL DRIVE (AWD) (for
versions/markets, where
provided)
This feature provides on-demand All-Wheel Drive
(AWD). The system is automatic with no driver inputs
or additional driving skills required. Under normal
driving conditions, the front wheels provide most of
the traction. If the front wheels begin to lose traction,
power is shifted automatically to the rear wheels. The
greater the front wheel traction loss, the greater the
power transfer to the rear wheels.
Additionally, on dry pavement under heavy throttle
input (where one may have no wheel spin), torque will
be sent to the rear in a pre-emptive effort to improve
vehicle launch and performance characteristics.
All wheels must have the same size and
type tires. Unequal tire sizes must not be
used. Unequal tire size may cause failure
of the power transfer unit .

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.

**Use only FIAT recommended lug nuts/bolts and clean
or remove any dirt or oil before tightening. 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.
(fig. 169)
After 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 t

he 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 (for
versions/markets, where
provided)
WARNING!
• Do not attempt to change a tire on the
si de

of the vehicle close to moving traf-
fic . Pull far enough off the road to avoid the
danger of being hit when operating the jack or
changing the wheel.
• Being under a jacked-up vehicle is dangerous.
The vehicle could slip off the jack and fall on you.
You could be crushed. Never put any part of your
body under a vehicle that is on a jack. If you need
to get under a raised vehicle, take it to a service
center where it can be raised on a lift .
• Never start or run the engine while the vehicle
is on a jack.
• The jack is designed to be used as a tool for
changing tires only.The jack should not be used to
lift the vehicle for service purposes. The vehicle
should be jacked on a firm level surface only.
Avoid ice or slippery areas.

NOTE:
• For vehicles so equipped, do not attempt to install acenter cap or wheel cover on the compact spare.
• Refer to “Compact Spare Tire” and to “Limited-Use Spare” under “Tires — General Information” in
“Technical Specifications” for additional warnings,
cautions, and information about the spare tire, its
use, and operation.
7. Install the wheel nuts with the cone-shaped end of the nut toward the wheel. Lightly tighten the wheel
nuts.
WARNING!
To avoid the risk of forcing the vehicle
off t

he jack, do not tighten the wheel
nuts fully until the vehicle has been lowered.
Failure to follow this warning may result in per-
sonal injury.
8. Lower the vehicle by turning the jack screw coun- terclockwise with the jack handle. 9. Finish tightening the lug nuts. Push down on the
wrench while at the end of the handle for increased
leverage. Tighten the lug nuts in a star pattern until
each nut has been tightened twice. Refer to “Torque
Specifications” in this section for proper lug nut
torque. If in doubt about the correct tightness, have
them checked with a torque wrench by your autho-
rized dealer or service station.
10. Lower the jack to its fully closed position.
11. Place the deflated (flat) tire in the cargo area. Do
not stow the deflated tire in the spare tire
stowage location. Have the deflated (flat) tire
repaired or replaced as soon as possible.
12. To stow the winch cable and retainer, fit the assembled jack-handle over the winch drive nut.
Rotate the jack-handle assembly clockwise until
you hear the winch mechanism click three times. It
cannot be over tightened.
13. Stow the jack-handle and jack. Remove the wheel blocks from the vehicle and release the park brake.
14. Check the tire pressure as soon as possible. Adjust the tire pressure as required.
