wheel size FIAT 500L 2017 2.G Owners Manual

Because air bag sensors measure vehicle deceleration
over time, vehicle speed and damage by themselves are
not good indicators of whether or not an air bag should
have deployed.
Seat belts are necessary for your protection in all
collisions, and also are needed to help keep you in
position, away from an inflating air bag.
When the ORC detects a collision requiring the front air
bags, it signals the inflator units. A large quantity of
non-toxic gas is generated to inflate the front air bags.
The steering wheel hub trim cover and the upper right
side of the instrument panel separate and fold out of the
way as the air bags inflate to their full size. The front air
bags fully inflate in less time than it takes to blink your
eyes. The front air bags then quickly deflate while
helping to restrain the driver and front passenger.
Knee Impact Bolsters
The Knee Impact Bolsters help protect the knees of the
driver and front passenger, and position the front
occupants for improved interaction with the front air
bags.
WARNING!
•Do not drill, cut, or tamper with the knee impact
bolsters in any way.
• Do not mount any accessories to the knee impact
bolsters such as alarm lights, stereos, citizen band
radios, etc.
Supplemental Driver Knee Air Bag
This vehicle is equipped with a Supplemental Driver
Knee Air Bag mounted in the instrument panel below
the steering column. The Supplemental Driver Knee Air
Bag provides enhanced protection during a frontal
impact by working together with the seat belts, preten-
sioners, and front air bags.
Supplemental Side Air Bags
Your vehicle is equipped with two types of side air
bags:
1. Supplemental Seat-Mounted Side Air Bags (SABs):
Located in the outboard side of the front seats. The
SABs are marked with a “SRS AIRBAG” or “AIR-
BAG” label sewn into the outboard side of the
seats.
40 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

As an added safety feature, your vehicle has been
equipped with a Tire Pressure Monitoring System
(TPMS) that illuminates a low tire pressure telltale
when one or more of your tires is significantly under-
inflated. Accordingly, when the low tire pressure telltale
illuminates, you should stop and check your tires as
soon as possible and inflate them to the proper pres-
sure. Driving on a significantly under-inflated tire
causes the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency and tire
tread life, and may affect the vehicle’s handling and
stopping ability.
Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver ’s responsibility to
maintain correct tire pressure, even if under-inflation
has not reached the level to trigger illumination of the
TPMS low tire pressure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system is
not operating properly. The TPMS malfunction indica-
tor is combined with the low tire pressure telltale. When
the system detects a malfunction, the telltale will flash
for approximately one minute and then remain continu-
ously illuminated. This sequence will continue uponsubsequent vehicle start-ups as long as the malfunction
exists. When the malfunction indicator is illuminated,
the system may not be able to detect or signal low tire
pressure as intended. TPMS malfunctions may occur for
a variety of reasons, including the installation of re-
placement or alternate tires or wheels on the vehicle
that prevent the TPMS from functioning properly. Al-
ways check the TPMS malfunction telltale after replac-
ing one or more tires or wheels on your vehicle, to
ensure that the replacement or alternate tires and
wheels allow the TPMS to continue to function prop-
erly.
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system op-
eration or sensor damage may result when using
replacement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Using aftermarket tire sealants may
cause the Tire Pressure Monitoring System (TPMS)

WARNING!
•The Electronic Stability Control (ESC) cannot
prevent the natural laws of physics from acting on
the vehicle, nor can it increase the traction af-
forded by prevailing road conditions. ESC cannot
prevent all accidents, including those resulting
from excessive speed in turns, driving on very
slippery surfaces, or hydroplaning. ESC also can-
not prevent collisions resulting from loss of ve-
hicle control due to inappropriate driver input for
the conditions. Only a safe, attentive, and skillful
driver can prevent accidents. The capabilities of
an ESC equipped vehicle must never be exploited
in a reckless or dangerous manner which could
jeopardize the user ’s safety or the safety of others.

tively affect the performance of the ESC system.
Changes to the steering system, suspension, brak-
ing system, tire type and size or wheel size may
adversely affect ESC performance. Improperly
inflated and unevenly worn tires may also de-
grade ESC performance. Any vehicle modifica-
tion or poor vehicle maintenance that reduces the
effectiveness of the ESC system can increase the
risk of loss of vehicle control, vehicle rollover,
personal injury and death.

ERM can only reduce the chance of wheel lift occurring
during severe or evasive driving maneuvers. It cannot
prevent wheel lift due to other factors, such as road
conditions, leaving the roadway, or striking objects or
other vehicles.
WARNING!
Many factors, such as vehicle loading, road condi-
tions, 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 jeopar-
dize the user’s safety or the safety of others.

CAUTION!
Because of the reduced ground clearance, do not
take your vehicle through an automatic car wash
with a compact or limited-use temporary spare
installed. Damage to the vehicle may result.
Spare Tire Matching Original Equipped Tire And
Wheel — If Equipped
Your vehicle may be equipped with a spare tire and
wheel equivalent in look and function to the original
equipment tire and wheel found on the front or rear
axle of your vehicle. This spare tire may be used in the
tire rotation for your vehicle. If your vehicle has this
option, refer to an authorized tire dealer for the recom-
mended tire rotation pattern.
Compact Spare Tire — If Equipped
The compact spare is for temporary emergency use
only. You can identify if your vehicle is equipped with
a compact spare by looking at the spare tire description
on the Tire and Loading Information Placard located on
the driver ’s side door opening or on the sidewall of thetire. Compact spare tire descriptions begin with the
letter “T” or “S” preceding the size designation. Ex-
ample: T145/80D18 103M.
T, S = Temporary Spare Tire
Since this tire has limited tread life, the original equip-
ment tire should be repaired (or replaced) and rein-
stalled on your vehicle at the first opportunity.
Do not install a wheel cover or attempt to mount a
conventional tire on the compact spare wheel, since the
wheel is designed specifically for the compact spare
tire. Do not install more than one compact spare tire and
wheel on the vehicle at any given time.
WARNING!
Compact and Collapsible spares are for temporary
emergency use only. With these spares, do not drive
more than 50 mph (80 km/h). Temporary use spares
have limited tread life. When the tread is worn to
the tread wear indicators, the temporary use spare
tire needs to be replaced. Be sure to follow the
warnings, which apply to your spare. Failure to do
so could result in spare tire failure and loss of
vehicle control.
254 STARTING AND OPERATING

Collapsible Spare Tire — If Equipped
The collapsible spare is for temporary emergency use
only. You can identify if your vehicle is equipped with
a collapsible spare by looking at the spare tire descrip-
tion on the Tire and Loading Information Placard
located on the driver ’s side door opening or on the
sidewall of the tire.
Collapsible spare tire description example: 165/80-17
101P.
Since this tire has limited tread life, the original equip-
ment tire should be repaired (or replaced) and rein-
stalled on your vehicle at the first opportunity.
Inflate collapsible tire only after the wheel is properly
installed to the vehicle. Inflate the collapsible tire using
the electric air pump before lowering the vehicle.
Do not install a wheel cover or attempt to mount a
conventional tire on the collapsible spare wheel, since
the wheel is designed specifically for the collapsible
spare tire.
WARNING!
Compact and Collapsible spares are for temporary
emergency use only. With these spares, do not drive
more than 50 mph (80 km/h). Temporary use spares
have limited tread life. When the tread is worn to
the tread wear indicators, the temporary use spare
tire needs to be replaced. Be sure to follow the
warnings, which apply to your spare. Failure to do
so could result in spare tire failure and loss of
vehicle control.
Full Size Spare — If Equipped
The full size spare is for temporary emergency use only.
This tire may look like the originally equipped tire on
the front or rear axle of your vehicle, but it is not. This
spare tire may have limited tread life. When the tread is
worn to the tread wear indicators, the temporary use
full size spare tire needs to be replaced. Since it is not
the same as your original equipment tire, replace (or
repair) the original equipment tire and reinstall on the
vehicle at the first opportunity.

STARTING AND OPERATING 255

Keep dismounted tires in a cool, dry place with as little
exposure to light as possible. Protect tires from contact
with oil, grease, and gasoline.
Replacement Tires
The tires on your new vehicle provide a balance of
many characteristics. They should be inspected regu-
larly for wear and correct cold tire inflation pressures.
The manufacturer strongly recommends that you use
tires equivalent to the originals in size, quality and
performance when replacement is needed. Refer to the
paragraph on “Tread Wear Indicator”. Refer to the Tire
and Loading Information placard or the Vehicle Certi-
fication Label for the size designation of your tire. The
Load Index and Speed Symbol for your tire will be
found on the original equipment tire sidewall. See the
Tire Sizing Chart example found in the “Tire Safety
Information” section of this manual for more informa-
tion relating to the Load Index and Speed Symbol of a
tire.
It is recommended to replace the two front tires or two
rear tires as a pair. Replacing just one tire can seriously
affect your vehicle’s handling. If you ever replace a
wheel, make sure that the wheel’s specifications match
those of the original wheels.It is recommended you contact your authorized tire
dealer or original equipment dealer with any questions
you may have on tire specifications or capability. Fail-
ure to use equivalent replacement tires may adversely
affect the safety, handling, and ride of your vehicle.
WARNING!
•
Do not use a tire, wheel size or rating other than
that specified for your vehicle. Some combina-
tions of unapproved tires and wheels may change
suspension dimensions and performance charac-
teristics, resulting in changes to steering, han-
dling, and braking of your vehicle. This can cause
unpredictable handling and stress to steering and
suspension components. You could lose control
and have a collision resulting in serious injury or
death. Use only the tire and wheel sizes with load
ratings approved for your vehicle.
• Never use a tire with a smaller load index or
capacity, other than what was originally equipped
on your vehicle. Using a tire with a smaller load
index could result in tire overloading and failure.
You could lose control and have a collision.

(20°C) and the measured tire pressure is 27 psi (186
kPa), a temperature drop to 20°F (-7°C) will decrease
the tire pressure to approximately 23 psi (159 kPa). This
tire pressure is sufficiently low enough to turn on the
Tire Pressure Monitoring Telltale Light. Driving the
vehicle may cause the tire pressure to rise to approxi-
mately 27 psi (186 kPa), but the Tire Pressure Monitor-
ing Telltale Light will still be on. In this situation, the
Tire Pressure Monitoring Telltale Light will turn off only
after the tires are inflated to the vehicle’s recommended
cold tire pressure value.
CAUTION!
•The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warnings have been established for the tire size
equipped on your vehicle. Undesirable system
operation or sensor damage may result when
using replacement equipment that is not of the
same size, type, and/or style. Aftermarket wheels
can cause sensor damage. Using aftermarket tire
sealants may cause the Tire Pressure Monitoring
System (TPMS) sensor to become inoperable.
(Continued)
CAUTION! (Continued)
After using an aftermarket tire sealant it is recom-
mended that you take your vehicle to an autho-
rized dealership to have your sensor function
checked.
• After inspecting or adjusting the tire pressure,
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the valve
stem, which could damage the Tire Pressure
Monitoring Sensor.
NOTE:
• The TPMS is not intended to replace normal tire care
and maintenance, or to provide warning of a tire
failure or condition.
• The TPMS should not be used as a tire pressure
gauge while adjusting your tire pressure.
• Driving on a significantly under-inflated tire causes
the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency and tire
tread life, and may affect the vehicle’s handling and
stopping ability.

STARTING AND OPERATING 263

CAUTION!
Driving with a hot cooling system could damage
your vehicle. If the pointer rises to the H (red) mark,
the instrument cluster will sound a chime. When
safe, pull over and stop the vehicle with the engine
at idle. Turn off the air conditioning and wait until
the pointer drops back into the normal range. If the
pointer remains on the H (red) mark for more than
a minute, turn the engine off immediately and call
for service.
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
