wheel size FIAT 500X 2019 Owner handbook (in English)

41)For the correct operation of the ESC
system, the tyres must necessarily be of
the same make and type on all wheels, in
perfect condition and, above all, of the
prescribed type and size.
42)ESC performance features must not
induce the driver to take unnecessary or
unwarranted risks. Your driving style must
always be suited to the road conditions,
visibility and traffic. The driver is, in any
case, responsible for safe driving.
43)For the correct operation of the TC
system, the tyres must of necessity be the
same make and type on all wheels, in
perfect condition and, above all, of the
prescribed type and dimensions.
44)TC performance features must not
induce the driver to take unnecessary or
unwarranted risks. Your driving style must
always be suited to the road conditions,
visibility and traffic. The driver is, in any
case, responsible for safe driving.
45)The TC system cannot overrule the
natural laws of physics, and cannot
increase the grip available according to the
condition of the road.
46)The TC system cannot prevent
accidents, including those due to excessive
speed on corners, driving on low-grip
surfaces or aquaplaning.
47)The capability of the TC must never be
tested irresponsibly and dangerously, in
such a way as to compromise personal
safety and the safety of others.
48)The PBA system cannot overrule the
natural laws of physics, and cannot
increase the grip available according to the
condition of the road.49)The PBA system cannot prevent
accidents, including those due to excessive
speed on corners, driving on low-grip
surfaces or aquaplaning.
50)The capability of the PBA system must
never be tested irresponsibly and
dangerously, in such a way as to
compromise the safety of the driver, the
other occupants of the vehicle or any other
road user.
51)The Hill Hold Control system is not a
parking brake; therefore, never leave the
vehicle without having engaged the electric
parking brake, turned the engine off and
engaged first gear, so that it is parked in
safe conditions (for further information read
the "Parking" paragraph in the "Starting
and driving" chapter).
52)There may be situations on small
gradients (less than 8%), with vehicle
laden, in which the Hill Hold Control system
may not activate, causing a slight reversing
motion and increasing the risk of collision
with another vehicle or object. The driver is,
in any case, responsible for safe driving.
53)DST is an aid for driving and does not
relieve the driver of responsibility for driving
the vehicle.
54)The performance of a vehicle with ERM
must never be tested in imprudent or
dangerous ways, with the possibility of
putting the safety of the driver or other
people at risk.
55)When towing trailers, the utmost
caution at the wheel is recommended.
Never exceed the maximum permitted
loads (see the description in the "Weights"
paragraph in the "Technical Specifications"
chapter).56)The TSC system cannot prevent
swerving for all trailers. If the system
activates during driving, reduce the speed,
stop the vehicle in a safe place and arrange
the load correctly to prevent the trailer from
swerving.

SAFETY

The LED on the button is off when the
system is switched on by the driver. The
LED is on if the system is deactivated
by the driver, faulty or temporarily
deactivated.
If the button is pressed with a system
failure, the LED flashes for about
5 seconds, then it stays on constantly.
When the ignition device is set to MAR
the Park Assist system keeps the last
status when the engine was switched
off (activated or deactivated) in its
memory.
After having been switched off, the Park
Assist system will stay in this condition
until the following engagement, even if
the ignition device is switched from
MAR to STOP and then again to MAR.Using wheels with different sizes from
those mounted at the time the car was
purchased could affect the system, not
allowing it to function properly.
System on activation/deactivation
(versions with 4 sensors)
Activation
The system is automatically activated
when reverse is engaged.
Deactivation
The system is automatically deactivated
whenever a gear other than reverse is
engaged.
System on activation/deactivation
(versions with 8 sensors)
Activation
The system, when it is on, is
automatically activated in the following
conditions:
when a forward gear is selected
(versions with manual transmission) or
D (Drive) position (versions with
automatic transmission/dual clutch
automatic transmission);
or
when reverse gear is selected
(versions with manual transmission) or
R position (versions with automatic
transmission/dual clutch automatic
transmission);
or
when the manual gear stick is in
neutral or the automatic transmission/
dual clutch automatic transmission lever
is in N (neutral) position and the car is
moving. The system stays on in case of
movement (either forwards or
backwards).
Deactivation
The system is automatically deactivated
in the following conditions:
if a gear other than reverse is
engaged, the rear sensors are
deactivated, while the front sensors
remain active until 15 km/h are
exceeded;
or
at speeds higher than 11 km/h with
reverse engaged (in this case, the LED
on the button on the instrument panel
switches on);
or
when with the car standing the
manual gear stick is in neutral or the
automatic transmission/dual clutch
automatic transmission lever is in P
(park) position.
Operation with a trailer
Versions with 4 sensors
The operation of the sensors is
automatically deactivated when the
trailer electric cable plug is inserted in

STARTING AND DRIVING

Check the tension of the snow chains
after the first few metres have been
driven.
IMPORTANT Using snow chains with
tyres with non-original dimensions may
damage the vehicle.
IMPORTANT Using different size or type
(M+S, snow, etc.) tyres between front
and rear axle may adversely affect
vehicle driveability, with the risk of losing
control of the vehicle and resulting
accidents.
SUGGESTIONS ABOUT
THE ROTATION OF THE
TYRES
The front and rear tyres are subject to
different loads and stress due to
steering, manoeuvres and braking. For
this reason they are subject to uneven
wear.
To resolve this problem, tyres should be
rotated at the appropriate time. Tyre
rotation means moving the wheels to a
different position, with respect to the
vehicle. The single wheel will therefore
operate on a different axle and, where
possible, on the opposite side of the
vehicle.Tyre rotation contributes to the
preservation of the grip and traction
performance on wet, muddy or snowy
roads, guaranteeing optimal driveability
of the vehicle.
In the case of irregular wear of the tyres
identify the cause and correct it as soon
as possible, by contacting a Fiat
Dealership.
WARNING
180)The road holding qualities of the car
also depend on the correct inflation
pressure of the tyres.
181)If tyre pressure is too low, it may
overheat and be severely damaged as a
result.
182)If the tyres are "unidirectional", do not
switch tyres from the right-hand side of the
vehicle to the left-hand side, and vice
versa. This type of tyres can only be
switched from the front axle to the rear axle
and vice versa, keeping them on the same
side of the vehicle.
183)Never submit alloy rims to repainting
treatments requiring the use of
temperatures exceeding 150°C. The
mechanical properties of the wheels could
be impaired.
184)The wheel rotation methods shown in
the text must NOT be used with one-way
tyres! This type of tyres can only be
switched from the front axle to the rear axle
and vice versa, keeping them on the same
side of the vehicle.185)Travelling with partially or completely
deflated tyres can cause safety problems
and damage the concerned tyre beyond
repair.
IMPORTANT
95)Keep your speed down when snow
chains are fitted; do not exceed 50 km/h.
Avoid potholes, do not drive over steps or
pavements and do not drive long distances
over roads without snow, to avoid
damaging both your vehicle and the road
surface.
