wheel size Alfa Romeo Stelvio 2019 Owner's Manual

If the car speed exceeds 6 mph
(10 km/h), but remains below 37 mph
(60 km/h) and the accelerator pedal is
released, as soon as the car gets close to
the set speed, the HDC system will brake
to bring the car to the set speed.
The driver can cancel HDC system
intervention at any time by pressing the
accelerator pedal.
System deactivation
The HDC system is deactivated, but
remains available, if one of the following
conditions is met:
the car is on a descent with insufficient
gradient, below 8%, or a level surface, or
is going uphill;
P (Park) mode is engaged.Disabling the system
53)
The system is disabled if one of the
following conditions is met:
fig. 57 button pressed;
Cruise Control / Active Cruise Control
is activated.
37 mph (60 km/h) is exceeded.
System deactivation is shown by the icon
on the display turning off.
WARNING
29)For maximum efficiency of the braking
system, a bedding-in period of about 500 km
(310 miles) is required: during this period it
is advisable to avoid sharp, repeated and
prolonged braking.
30)If the ABS intervenes, this indicates that
the grip of the tyres on the road is nearing its
limit: you must slow down to a speed
compatible with the available grip.
31)The ABS cannot overrule the natural
laws of physics, and cannot increase the grip
available according to the condition of the
road.
32)The ABS cannot prevent accidents,
including those due to excessive speed on
corners, driving on low-grip surfaces or
aquaplaning.
33)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.34)For the correct operation of the ABS, 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.
35)There may be a brief delay in shifting to
AWD mode after a tyre slipping event.
36)When a DTC system failure symbol
appears, the driver must be aware of the
different driving reaction and therefore
reduce the speed. The symbol
warns the
driver not to drive in areas that require
four-wheel drive or on snow-covered roads.
37)The ESC system cannot alter the natural
laws of physics, and cannot increase grip,
which depends on the condition of the road.
38)The ESC system cannot prevent
accidents, including those due to excessive
speed on corners, driving on low-grip
surfaces or aquaplaning.
39)The capability of the ESC system must
never be tested irresponsibly and
dangerously, in such a way as to compromise
personal safety and the safety of others.
40)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.
41)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.
42)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.

the warning limit for any reason, including
the effects of low temperature and
normal loss of pressure from the tyre.
The TPMS will stop indicating insufficient
tyre pressure when it is equal to or
greater than the prescribed cold inflation
pressure. Therefore, if insufficient tyre
pressure is indicated (
warning light
on instrument panel on), increase the
inflation pressure up to the prescribed
cold inflation value.
The system automatically updates and
warning light
switches off each time
the system receives the updated
inflation pressures. The vehicle might
need to be driven at a speed higher than
about 15.5 mph (25 km/h) up to
20 minutes for the TPMS to receive this
information.
Operating example
Supposing that the prescribed cold
inflation pressure (i.e. vehicle stationary
for at least 3 hours) is 33.4 psi (2.3 bar),
if the ambient temperature is 68°F
(20°C) and the detected tyre pressure is
28.3 psi (1.95 bar), a temperature
reduction of 19.4°F (−7°C) results in a
decrease in tyre pressure, bringing it to
approximately 24 psi (1.65 bar). This
pressure is sufficiently low to activate
the
warning light.
Heating of tyres due to driving the
vehicle may increase tyre pressure up toapproximately 28.3 psi (1.95 bar), but
the
warning light will stay on. In this
situation, the warning light will switch off
only after the tyres are inflated to the
prescribed cold pressure value for the
car.
IMPORTANT The TPMS is designed for
original tyres and wheels. The prescribed
pressures and consequent alarm
thresholds set in the TPMS are based on
the dimensions of the tyres fitted on the
vehicle. Using spare wheels of a size, type
and/or design different from the original
ones may cause an irregular operation of
the system and damage the sensors.
Aftermarket fitted wheels may damage
the sensors. Using aftermarket tyre
sealants may damage the Tyre Pressure
Monitoring System (TPMS) sensor. If
aftermarket tyre sealant is used it is
recommended to go to an Alfa Romeo
Dealership to have the sensors checked.
After checking or adjusting the tyre
inflation pressure, always refit the valve
cap to prevent humidity and dirt from
entering, these may damage the Tyre
Pressure Monitoring System sensor.
LOW TYRE PRESSURE WARNING
If an insufficient pressure value is
detected on one or more tyres, the
warning light on the instrument panel
switches on and the dedicated messages
are shown on the display. The system alsohighlights the tyre or tyres with
insufficient pressure graphically. An
acoustic warning is also emitted.
In this case, stop the car, check the
inflation pressure of each tyre and inflate
them to the correct cold inflation
pressure value, shown on the display or in
the dedicated TPMS menu.
TPMS TEMPORARILY DISABLED
TPMS check message
If a system failure is present, the
warning light flashes for about
75 seconds and then stays on solid. An
acoustic warning is also emitted.
A dedicated message and dashes "– –"
instead of the pressure value are shown
on the display, to indicate that detection
is impossible.
When the ignition device is set to STOP
and then back to ON, the indication
sequence repeats provided that the
failure is still resent.
The
warning light switches off when
the failure condition disappears and the
pressure value is displayed again in place
of the dashes.
A fault in the system could occur in the
following cases:
intense radio-frequency interference
may prevent the correct operation of the
TPMS. This condition will be indicated by
a dedicated message on the display. The
83

61)Should one or more wheels be fitted
without sensors, the system will no longer be
available and a warning message will be
shown on the display, until wheels with
sensors are fitted again.
62)The TPMS cannot indicate sudden tyre
pressure drops (e.g. if a tyre bursts). In this
case, stop the vehicle, braking with caution
and avoiding abrupt steering.
63)Changes in outside temperature may
cause tyre pressures to vary. The system
may temporarily indicate insufficient
pressure. In this case, check the tyre
pressure when cold and, if necessary,
restore the inflation values.
64)Replacing standard tyres with winter
tyres and vice versa requires TPMS system
adjustment that must only be performed by
Alfa Romeo Dealerships.
65)When a tyre is removed, it is advisable
to replace the rubber valve seal as well:
contact an Alfa Romeo Dealership. The
fitting/removal of the tyres and/or rims
require special care. To avoid damaging or
fitting the sensors incorrectly, tyre and/or
rim fitting/removal operations should only
be carried out by specialised staff. Contact
an Alfa Romeo Dealership.
IMPORTANT
19)The system may have limited or absent
operation due to weather conditions such as:
heavy rain, hail, thick fog, heavy snow.
20)The section of the bumper before the
sensor must not be covered with adhesives,
auxiliary headlights or any other object.21)System intervention might be
unexpected or delayed when other vehicles
transport loads projecting from the side,
above or from the rear, with respect to the
normal size of the vehicle.
22)Operation can be adversely affected by
any structural change made to the vehicle,
such as a modification to the front geometry,
tyre change, or a heavier load than the
standard load of the vehicle.
23)Incorrect repairs made on the front part
of the vehicle (e.g. bumper, chassis) may alter
the position of the radar sensor, and
adversely affect its operation. Go to an Alfa
Romeo Dealership for any operation of this
type.
24)Do not tamper with nor carry out any
intervention on the radar sensor or on the
camera on the windscreen. In the event of a
sensor failure, contact an Alfa Romeo
Dealership.
25)Do not wash with high-pressure jets in
the bumper lower area: in particular do not
operate on the system's electrical connector.
26)Be careful in the case of repairs and new
paintings in the area around the sensor
(panel covering the sensor on the left side of
the bumper). In the event of a frontal impact
the sensor may automatically deactivate
and display a warning to indicate that the
sensor needs to be repaired. Even without a
malfunction warning, deactivate the system
operation if you think that the position of the
radar sensor has changed (e.g. due to
low-speed frontal impact as during parking
manoeuvres). In these cases, go to an Alfa
Romeo Dealership to have the radar sensor
realigned or replaced.27)When towing a trailer, a vehicle or during
loading manoeuvres on a vehicle transporter
(or in vehicle for transport), the system must
be deactivated via the Connect system.
28)The Tire Repair Kit, provided with the
vehicle, is compatible with the TPMS
sensors. Using sealants different from that
in the original kit may compromise its
operation. If sealants not equivalent with the
original ones are used, it is recommended to
have the TPMS sensor operation checked by
a qualified repair centre.

Before embarking on a long trip, and
every two weeks, check the tyre inflation
pressure. Check the tyres when cold.
SNOW CHAINS
76)
Rear Wheel Drive and All-wheel drive
versions
It is possible to fit 0.5 in (13 mm) chains
on all the tyres except for R20.
Important notes
The use of snow chains should be in
compliance with local regulations of each
country. In certain countries, tyres
marked with code M+S (Mud and Snow)
are considered as winter equipment;
therefore their use is equivalent to that
of the snow chains.
IMPORTANT The snow chains may be
applied only to the rear wheel tyres.
Installing them on the rear wheel tyres
could damage the suspension and
transmission.
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 car
driveability, with the risk of losing control
of the car 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 (6200 /
9300 miles (10000 / 15000 km)).
Inverting the tyres means moving them
to different positions on the same side of
the car (front to back and vice versa).
IMPORTANT Crossing the tyres is not
advised, so placing a tyre on a different
axle on the other side of the car is
impossible.
Tyre rotation contributes to the
preservation of the grip and traction
performance on wet, muddy or snowy
roads, guaranteeing optimal driveability
of the car.In the case of irregular wear of the tyres
identify the cause and correct it as soon
as possible, by contacting an Alfa Romeo
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)Never submit alloy rims to repainting
treatments requiring the use of
temperatures exceeding 150°C. The
mechanical properties of the wheels could
be impaired.
IMPORTANT
76)Keep your speed down when snow chains
are fitted; do not exceed 50 km/h (or the
equivalent in miles). 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.
