2018 FIAT FULLBACK wheel size

INSTALLATION OF ACCESSORIES
Before fitting any accessories, please consult your authorised Fiat Dealership.
IMPORTANT Your vehicle is equipped with a diagnosis connector for checking and servicing the electronic control system. Do
not connect a device other than a diagnosis tool for inspections and service to this connector. Otherwise, the battery could be
discharged, the electronic devices of the vehicle could malfunction, or other unexpected problems could result. In addition,
malfunctions caused by connecting a device other than a diagnosis tool may not be covered under warranty.
The installation of accessories, optional parts, etc., should only be carried out within the limits prescribed by law in your country,
and in accordance with the guidelines and warnings contained within the documents accompanying this vehicle. Only FCA Italy
S.p.A. approved accessories should be fitted to your vehicle.
Improper installation of electrical parts could cause fire, please refer to the Modification/ alteration to the electrical or fuel
systems section within this owner’s manual.
Using a cellular phone or radio set inside the vehicle without an external antenna may cause electrical system interference,
which could lead to unsafe vehicle operation.
Tyres and wheels which do not meet specifications must not be used. Refer to the “Specifications” section for information
regarding wheel and tyre sizes.
Do not fail to read the accessories manuals prior to the installation of accessories, parts or other modifications to the vehicle!
IMPORTANT POINTS!
Due to a large number of accessories and replacement parts of different manufactures available in the market, it is not possible,
not only for FCA Italy S.p.A. but also an authorised Fiat Dealership, to check whether the attachment or installation of such
parts affects the overall safety of your vehicle.
Even when such parts are officially authorised, for example by a “general operators permit” (an appraisal for the part) or through
the execution of the part in an officially approved manner of construction, or when a single operation permit following the
attachment or installation of such parts, it cannot be deduced from that alone, that the driving safety of your vehicles has not
been affected.
Consider also that there basically exists no liability on the part of the appraiser or the official. Maximum safety can only be
ensured with parts recommended, sold and fitted or installed by an authorised Fiat Dealership (replacement with original FCA
Italy S.p.A. spare parts). The same also pertains to modifications of vehicles with respect to the production specifications. For
safety reasons, do not attempt any modifications other than those that follow the recommendations of an authorised Fiat
Dealership.

WARNING
47)All adjustments must only be carried
out with the vehicle stationary and the
engine off. Head restraints must be
adjusted so that the head, rather than the
neck, rests on them. Only in this case can
they protect your head correctly. To take
best advantage of the protection provided
by the head restraint, adjust the seat back
so that you are sitting up straight and your
head is as close to the head restraint as
possible.
48)Driving without the head restraints in
place can cause you and your passengers
serious injury or death in an accident. To
reduce the risk of injury in an accident,
always make sure the head restraints are
installed and properly positioned when the
seat is occupied.
49)Never place a cushion or similar device
on the seatback. This can adversely affect
head restraint performance by increasing
the distance between your head and the
restraint.
50)When a person sits in the middle
seating position of the rear seat, pull up the
head restraint to a height at which it locks
in position fig. 52. Be sure to make this
adjustment before starting to drive. Serious
injuries could otherwise be suffered in the
result of an impact (Double cab).
51)Make sure that the height adjusting
knob (A) is correctly adjusted as shown in
the illustration fig. 56, and also lift the head
restraints to ensure that they do not come
out of the seatback.52)The shape and size of the head
restraint differs according to the seat.
Always use the correct head restraint
provided for the seat and do not install the
head restraint in the wrong direction fig. 57.

GETTING TO KNOW YOUR VEHICLE

209)To prevent failure of the ABS, be sure
all 4 wheels and tyres are the same size
and the same type.
210)Do not install any aftermarket limited
slip differential (LSD) on your vehicle. The
ABS may stop functioning properly.
211)The ABS exploits the grip available to
the full, but it cannot improve it. Therefore,
you should take great care when driving on
slippery surfaces, without taking
unnecessary risks.
212)When the ABS intervenes and you
notice the brake pedal pulsating, keep the
pedal pushed down and don’t be alarmed.
This will help you to stop in the shortest
distance possible, depending on the road
conditions.
213)If the ABS intervenes, it means you
have almost reached the grip limit between
the tyres and the road surface: slow down
to make sure that you drive in accordance
with the available grip.
214)The ABS cannot overrule the natural
laws of physics, and can’t increase the grip
available according to the condition of the
road.
215)The ABS cannot prevent accidents,
including those due to excessive speed on
corners, driving on low-grip surfaces or
aquaplaning.
216)The capability of the ABS must never
be tested irresponsibly and dangerously, in
such a way as to compromise personal
safety and the safety of others.217)Do not over-rely on the ESC. Even the
ESC cannot prevent the natural laws of
physics from acting on the vehicle. This
system, like any other system, has limits
and cannot help you to maintain traction
and control of the vehicle in all
circumstances. Reckless driving can lead
to accidents. It is the driver’s responsibility
to drive carefully. This means into account
the traffic, road and environmental
conditions.
218)The ESC system cannot prevent
accidents, including those due to excessive
speed on corners, driving on low-grip
surfaces or aquaplaning.
219)Be sure to use the same specified
type and size of tyre on all 4 wheels.
Otherwise, the ESC may not work
correctly.
220)Do not install any aftermarket limited
slip differential (LSD) on your vehicle. The
electronic stability control function may
stop functioning properly.
221)For safety reasons, the “ESC OFF”
switch should only be operated when the
vehicle is stopped.
222)Be sure to keep the electronic stability
control function on while driving in normal
circumstances.
223)When driving a vehicle on a snowy or
icy road, be sure to install snow tyres and
drive the vehicle at moderate speeds.AUXILIARY DRIVING
SYSTEMS
Hill Start Assist (where provided)
The hill start assist makes it easy to
start off on a steep uphill slope by
preventing the vehicle from moving
backwards. It keeps the braking force
for approximately seconds when you
move your foot from the brake pedal to
the accelerator pedal.
81) 82)
224) 225)
To operate
1. Stop the vehicle completely using the
brake pedal.
2. On vehicles equipped with M/T,
place the gearshift lever into the 1st
position. On vehicles equipped with
A/T, place the selector lever into the “D”
position.
NOTE When reversing on an uphill
slope, place the selector lever or
gearshift lever into the “R” position.
3. Release the brake pedal and the hill
start assist will maintain the braking
force applied while stopping for
approximately 2 seconds.
4. Depress the accelerator pedal and
the hill start assist gradually will
decrease the braking force as the
vehicle starts moving.

SAFETY

WARNING
239)When attempting to rock your vehicle
out of a stuck position, be sure that the
area around the vehicle is clear of people
and physical objects. The rocking motion
may cause the vehicle to suddenly launch
forward or backward, causing injury or
damage to nearby people or objects.
240)Go straight up. Do not try to traverse
across a steep slope.
241)If you begin to lose traction, ease off
the accelerator pedal and gently turn the
steering wheel alternatively left and right to
regain adequate traction again.
242)Avoid snaking down a sharp grade.
Descend the grade as straight as possible.
CAUTIONS ON
HANDLING OF
4 WHEEL DRIVE
VEHICLES
Tyres and wheels
Since the driving torque can be applied
to the 4 wheels, the performance of the
vehicle when operating in 4-wheel drive
is greatly affected by the condition of
the tyres.
Pay close attention to the tyres.
Install specified tyres on all wheels.
Refer to “Tyres and wheels”.
Be sure to the appropriate tyre
inflation pressure according to no cargo
or cargo. Refer to “Tyre inflation
pressures”.
Be sure to fit all 4 tyres and wheels of
the same size and type. When
replacement of any of the tyres or
wheels is necessary, replace all of them.
All tyres should be rotated whenever
the wear difference between the front
and rear tyres is recognizable.
Good vehicle performance cannot be
expected if there is a difference in wear
between tyres. Refer to “Tyre rotation”.
Check the tyre inflation pressure
regularly.
150)
Towing
If towing is necessary, we recommend
you to have it done by a Fiat Dealership
or a commercial tow truck service. In
the following cases, transport the
vehicle using a tow truck.
The engine runs but the vehicle does
not move or abnormal noise is
produced.
Inspection of the vehicle’s underside
reveals that oil or some other fluid is
leaking.
If a wheel gets stuck in a ditch, do not
try to tow the vehicle. Please contact
your Fiat Dealership or a commercial
tow truck service for assistance.
Only when you cannot receive a towing
service from a Fiat Dealership or
commercial tow truck service, tow your
vehicle carefully in accordance with the
instructions given in “Towing”.
NOTE The regulations concerning
towing may differ from country to
country. It is recommended that you
obey the regulations of the area where
you are driving your vehicle.

STARTING AND DRIVING

151)
Jacking up a 4-wheel drive vehicles
243)
Clutch operation
Quick or slight clutch engagement
made while the engine is running at
high speed will cause damage to the
clutch and transmission because the
tractive force is very great. Operate the
pedal slowly and positively.
IMPORTANT
150)Always use tyres of the same size,
same type, and same brand which have no
wear differences. Using the tyres which
differ in size, type, brands or the degree of
wear or the inappropriate tyre inflation
pressure, will increase the differential oil
temperature, resulting in possible damage
to the driving system. Further, the drive
train will be subjected to excessive loading,
possibly leading to oil leakage, component
seizure, or other serious faults.
151)Transport the vehicle with the driving
wheels on a carriage (Type C or D) as
illustrated. Never try to tow with the front or
rear wheels on the ground (Type A or B) as
illustrated. This could result in damage to
the drivetrain, or unstable towing.
WARNING
243)Do not crank the engine while jacking
up the vehicle. The tyre on the ground may
turn and the vehicle may roll off the jack.
BRAKING SYSTEM
All the parts of the brake system are
critical to safety. We recommend you to
have the vehicle checked at regular
intervals according to the service
booklet.
244)
Brake system
The service brake is divided into two
brake circuits. And your vehicle is
equipped with power brakes. If one
brake circuit fails, the other is available
to stop the vehicle. If your vehicle
should lose the power assist for some
reason, the brakes will still work.
In these situations even if the brake
pedal moves down to the very end of
its possible stroke or resists being
depressed, keep depressing the brake
pedal down harder and further than
usual; stop driving as soon as possible
and have the brake system repaired.
245) 246)
Warning lamp
The brake warning lamp illuminates to
indicate a fault in the braking system.
Refer to “Brake warning lamp”.
When brakes are wet
Check the brake system while driving at
a low speed immediately after starting,
especially when the brakes are wet, to
confirm they work normally.

311)Stop jacking up the vehicle as soon
as the tyre is raised off the ground. It is
dangerous to raise the vehicle any higher.
Do not get under your vehicle while using
the jack. Do not bump the raised vehicle or
leave it sitting on the jack for a long time.
Both are very dangerous. Do not use a jack
except the one that came with your
vehicle. The jack should not be used for
any purpose other than to change a tyre.
No one should be in your vehicle when
using the jack. Do not start or run the
engine while your vehicle is on the jack. Do
not turn the raised wheel. The tyres still on
the ground could turn and make your
vehicle fall off the jack.
312)Do not get under your vehicle while
using the jack.
313)Do not bump the raised vehicle or
leave it sitting on the jack for a long time.
Both are very dangerous.
314)Do not use a jack except the one that
came with your vehicle.
315)The jack should not be used for any
purpose other than to change a tyre.
316)No one should be in your vehicle
when using the jack.
317)Do not start or run the engine while
your vehicle is on the jack.
318)Do not turn the raised wheel. The
tyres still on the ground could turn and
make your vehicle fall off the jack.
319)Handle the wheel carefully when
changing the tyre, to avoid scratching the
wheel surface.
320)Mount the spare wheel with the valve
stem K) facing outboard fig. 0. If you
cannot see the valve stem (K), you have
installed the wheel backwards.Operating the vehicle with the spare wheel
installed backwards can cause vehicle
damage and result in an accident.
321)Be sure to open the release valve
slowly. If it is opened quickly, the vehicle will
drop abruptly and the jack may come out
of position, causing a serious accident.
322)Never use your foot or a pipe
extension for extra force in the wheel nut
wrench. If you do so, you will tighten the
nut too much.
323)The tyre pressure should be
periodically checked and maintained at the
specified pressure while the tyre is stowed.
324)After changing the tyre and driving the
vehicle about 1,000 km, retighten the wheel
nuts to make sure that they have not come
loose.
325)If the steering wheel vibrates when
driving after changing the tyre, we
recommend you to have the tyres checked
for balance.
326)Do not mix one type of tyre with
another or use a different size from the one
listed. This would cause early wear and
poor handling.
327)The spare wheel should always be
securely in position. If a flat tyre is changed,
put the flat tyre in the spare wheel
mounting position with the wheel outer
surface upward, and use the wheel nut
wrench to secure it firmly.
328)Never tamper with the inflation valve.
Never introduce tools of any kind between
rim and tyre. Check tyre and spare wheel
pressure regularly, referring to the values
shown in the "Technical specifications"
section.329)The moving components of the jack
(screw and joints) can also cause injuries:
do not touch them. If you come into
contact with lubricating grease, clean
yourself thoroughly.
IMPORTANT
166)Avoid using different size tyres from
the one listed and the combined use of
different types of tyres, as this can affect
driving safety.
167)Even if a wheel has the same rim size
and offset as the specified type of wheel,
its shape may prevent it from being fitted
correctly. Consult an authorised Fiat
Dealership before using wheels that you
have.
168)When installing or removing the spare
wheel, please observe the followings. If you
do not follow them, it could result in break
the spare wheel carrier. Do not use the
power tool. Use the wheel nut wrench
stowed on the vehicle. Do not apply a force
of 400 N or more at the end of the wheel
nut wrench.
169)Never apply oil to either the wheel
bolts or the nuts or they will tighten too
much.
170)If the release valve is loosened too
much (2 or more turns) in the anticlockwise
direction, the jack’s oil will leak and the jack
cannot be used.
171)Close the release valve slowly when
lowering the vehicle, or the valve may be
damaged.
225

Snow tyres
406)
223) 224)
The use of snow tyres is recommended
for driving on snow and ice. To preserve
driving stability, mount snow tyres of the
same size and tread pattern on all four
wheels. Snow tyres worn more than 50
% are no longer suitable for use as
snow tyres. The pattern depth shall be
at least 3mm (for markets / versions,
where provided). Snow tyres which do
not meet specifications must not be
used.
NOTE The laws and regulations
concerning snow tyres (driving speed,
required use, type, etc.) vary. Find out
and follow the laws and regulations in
the area you intend to drive.
NOTE If flange nuts are used on your
vehicle, change to tapered nuts when
steel wheels are used.NOTE For markets / versions, where
provided, the identification letters
indicated on the winter tyres provide
information on the permissible speeds
for M&S tyres:
QMS: up to 160 kph
TMS: up to 190 kphThe respective
maximum speed should absolutely be
observed and a signboard to be
introduced into the field of view of the
driver, in case the maximum vehicle
speed indicated in the vehicle
registration a certificate is greater.
Snow traction device
(tyre chains)
If snow traction device (tyre chains)
have to be used, ensure that they are
fitted only on the drive wheels (rear) in
accordance with the manufacturer’s
instructions.
On 4WD vehicles in which the driving
power is distributed preferentially to the
rear wheels, ensure that the snow
traction device (Tyre chains) are fitted
on the rear. Use only snow traction
device (Tyre chains) which are designed
for use with the tyres mounted on the
vehicle: use of the incorrect size or type
of snow traction device (Tyre chains)
could result in damage to the vehicle
body. Contact a Fiat Dealership before
putting on snow traction device (tyre
chains). The max. snow traction device
(tyre chains) height is as follows.

When driving with snow traction device
(tyre chains) on the tyres, do not drive
faster than 50 km/h. When you reach
roads that are not covered in snow,
immediately remove the snow traction
device (tyre chains).
225) 226) 227) 228) 229) 230) 231) 232)
The laws and regulations concerning
the use of snow traction device (tyre
chains) vary. Always follow local laws
and regulations. In most countries, it is
prohibited by the law to use of snow
traction device (tyre chains) on roads
without snow.
WARNING
402)Driving with tyres that are worn,
damaged or improperly inflated can lead to
a loss of control or blow out of the tyres
which can result in a collision with serious
or fatal injury.
403)Remember that the road holding
qualities of your vehicle also depend on the
correct inflation pressure of the tyres.
404)If the pressure is too low, the tyre will
overheat and could be seriously damaged.

405)Never submit alloy rims to repainting
treatments requiring the use of
temperatures exceeding 150°C. The
mechanical properties of the wheels could
be impaired.
406)Avoid switching the tyres from the
right side of the vehicle to the left side and
vice versa.
IMPORTANT
218)Always use tyres of the same size,
same type, and same brand, and which
have no wear differences. Using tyres of
different size, type, brands or degree of
wear, will increase the differential oil
temperature, resulting in possible damage
to the driving system. Further, the drive
train will be subjected to excessive loading,
possibly leading to oil leakage, component
seizure, or other serious faults.
219)Avoid using different size tyres from
the one listed and the combined use of
different types of tyres, as this can affect
driving safety.
220)Even if a wheel has the same rim size
and offset as the specified type of wheel,
its shape may prevent it from being fitted
correctly. Consult a Fiat dealership before
using wheels that you have.221)If the tyres have arrows (A) indicating
the correct direction of rotation, swap the
front and rear tyres on the left hand side of
the vehicle and the front and rear tyres on
the right hand side of the vehicle separately.
Keep each tyre on its original side of the
vehicle. When fitting the tyres, make sure
the arrows point in the direction in which
the wheels will turn when the vehicle moves
forward. Any tyre whose arrow points in the
wrong direction will not perform to its full
potential.
222)Avoid the combined use of different
types of tyres. Using different types of tyres
can affect vehicle performance and safety.
223)If winter tyres with a lower speed
rating than that indicated in the Registration
Document are used, do not exceed the
maximum speed corresponding to the
speed rating of the tyres used.
224)Observe permissible maximum speed
for your snow tyres and the legal speed
limit.
225)Choose a clear straight stretch of road
where you can pull off and still be seen
while you are fitting the snow traction
device (Tyre chains).
226)Do not fit snow traction device (Tyre
chains) before you need them. This will
wear out your tyres and the road surface.
227)After driving around 100-300 metres,
stop and retighten the snow traction device
(Tyre chains).
228)Drive cautiously and do not exceed
50 km/h. Remember that preventing
accidents is not the purpose of snow
traction device (tyre chains).
229)When snow traction device (Tyre
chains) are installed, take care that they do
not damage the disc wheel or body.230)An aluminium wheel can be damaged
by a snow traction device (Tyre chains)
while driving. When fitting a snow traction
device (Tyre chains) on an aluminium wheel,
take care that any part of the snow traction
device (Tyre chains) and fitting cannot be
brought into contact with the wheel.
231)When installing or removing a snow
traction device (Tyre chains), take care that
hands and other parts of your body are not
injured by the sharp edges of the vehicle
body.
232)Install the snow traction device (Tyre
chains) only on the rear tyres and tighten
them as tightly as possible with the ends
securely fastened.
