2018 Alfa Romeo Stelvio temperature sensor

Humidity Sensor
The Humidity Sensor helps to prevent the
windows from fogging up. The AUTO
function (indicator illuminated) must be
on for the Humidity Sensor to function.
When outside temperature is low, the
system may turn the compressor on and
turn air recirculation off for safer driving.
Switching Off/On The Climate Control
System
Switching Off The Climate Control
System
Rotate the Air Speed Adjustment Knob
completely counterclockwise to turn off
the Climate Control System.
With the air conditioner off:
Air recirculation is on
The A/C compressor is off
The fan is off
The heated rear window can be
activated/deactivated
Note: The climate control system stores
the previously set temperatures and
resumes operation when any button on
the system is pushed.
Switching On The Climate Control
System
To switch the climate control system on
in automatic mode, push the AUTO
button.
Stop/Start
The Stop/Start system shuts off the
engine when vehicle speed is 0 mph
(0 km/h), and the climate control system
will continue to maintain comfort within
the vehicle.
Stop/Start will deactivate in the
following scenarios:
The climate control system is in AUTO
mode (indicator illuminated), and the
vehicle has yet to reach the set
temperature
The climate control system is in LO
maximum cooling
The climate control system is in HI
maximum heating
The climate control system is in the
MAX-DEF status
When the Stop/Start system is active,
the engine will restart if the inside
temperature changes significantly, or if
the LO setting, or MAX-DEF setting, is
activated.
With Stop/Start system on, air flow is
reduced to keep the compartment
comfort conditions for longer.
Until the temperature drastically
changes within the cabin, the climate
control system will continue to maintain
the temperature while the engine is off.
By deactivating the Stop/Start system
with the
button located on the dashboard, the climate control system
will take priority over the engine shutting
off.
Note:
In harsh climate conditions, limit the
use of the Stop/Start system to prevent
the compressor from continuously
switching on and off. This will cause
rapid misting of the windows and the
accumulation of humidity in the
passenger compartment.
When the Stop/Start system is on,
the climate control system will always
take air in from outside, reducing the
probability of the windows fogging up.
System Maintenance
In winter, the Climate Control System
must be turned on at least once a month
for approximately ten minutes.
Have the system inspected at an
authorized dealer before the summer.

Warning LightsWhat It Means What To Do
ENGINE OIL CHANGE REQUIRED — IF EQUIPPED
The telltale is illuminated only for a limited time.
Note:After the first indication, each time the engine is started
the symbol will continue to illuminate as described above
until the oil is changed.
If the telltale flashes, this does not mean that there is a
fault on the vehicle, rather it simply reports that it is now
necessary to change the oil as a result of regular use of
the vehicle. The deterioration of engine oil is accelerated
by using the vehicle for short drives, preventing the
engine from reaching operating temperature.Contact an authorized dealer as soon as possible.
Caution!
Deteriorated engine oil should be replaced as soon as possible after the symbol is switched on, and never more than 500 miles (805 km) after it
first switches on. Failure to observe the above may result in severe damage to the engine and invalidate the New Vehicle Limited Warranty. When
this symbol comes on, it does not mean that the level of engine oil is low, so if it flashes you do not need to top up the engine oil.

GETTING TO KNOW YOUR INSTRUMENT PANEL

Beginning with the next ignition switch
cycle, the TPMS will no longer chime or
display the “SERVICE TPM SYSTEM”
message in the instrument cluster.
Instead, dashes (--) will remain in place of
the pressure values.
To reactivate the TPMS, replace all four
wheel and tire assemblies (road tires)
with tires equipped with TPM sensors.
Then, drive the vehicle for up to
20 minutes above 15 mph (24 km/h). The
TPMS will chime, the "TPM Warning
Light" will flash on and off for 75 seconds
and then turn off. The instrument cluster
will display the “SERVICE TPM SYSTEM”
message and then display pressure
values in place of the dashes. On the next
ignition switch cycle the "SERVICE TPM
SYSTEM" message will no longer be
displayed, as long as no system fault
exists.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
underinflated tire will cause the tire to
overheat, and can lead to tire failure.
Underinflation also reduces fuel
efficiency and tire tread life, and may
affect the vehicle’s handling and
stopping ability.
The TPMS is not a substitute for
proper tire maintenance, and it is the
driver’s responsibility to maintain
correct tire pressure using an accurate
tire pressure gauge, even if
underinflation has not reached the level
to trigger illumination of the “Tire
Pressure Monitoring Warning Light”.
Seasonal temperature changes will
affect tire pressure, and the TPMS will
monitor the actual tire pressure in the
tire.

will be enabled. Exiting remote start will
resume previous operation, except if the
Windshield Wiper De-Icer is active.
The Windshield Wiper De-Icer timer and
operation will continue.
Cold Weather Operation
To prevent possible engine damage while
starting at low temperatures, this vehicle
will inhibit engine cranking when the
ambient temperature is less than –22° F
(–30° C) and the oil temperature sensor
reading indicates an engine block heater
has not been used. An externally-
powered electric engine block heater is
available as optional equipment or from
your authorized dealer.
The message “plug in engine heater” will
be displayed in the instrument cluster
when the ambient temperature is below
5° F (–15° C) at the time the engine is
shut off as a reminder to avoid possible
crank delays at the next cold start.
Caution!
Use of the recommended oil and adhering to
the prescribed oil change intervals is
important to prevent engine damage and
ensure satisfactory starting in cold
conditions.
Extended Park Starting
If the vehicle has not been started or
driven for at least 90 days, it is advisable
to follow the indications below. To start the engine, proceed as follows:
1. Briefly push the ignition button
2. If the engine does not start, wait five
seconds and let the starter cool down and
then repeat the starting procedure
3. If the engine does not start after eight
attempts, let the starter cool down for at
least 10 seconds, and then repeat the
starting procedure
If the problem persists, contact your
authorized dealer.
Note:
After prolonged vehicle inactivity,
very difficult starting, that can be noticed
through rapid fatigue of the starter,
might also be due to a partially flat
battery. In this case, refer to "Jump
Starting" in "In Case Of Emergency".
If Engine Fails To Start
Starting the Engine with Key Fob
Battery Run Down or Drained
If the ignition does not respond when the
button is pushed, the key fob battery
might be run down or drained. Therefore,
the system does not detect the presence
of the key fob in the vehicle, and will
display a dedicated message.
In this case, follow the instructions
outlined in "Starting With A Discharged
Key Fob Battery" in the "Getting To Know
Your Vehicle" chapter, and start the

The activation of the system is indicated
by the
symbol lighting up on the
display. In this condition, the light on the
button is off.
System Deactivation
A message will appear on the display
when the system is deactivated. In this
condition, the light on the button is on.
Note: Each time the engine is started,
the system is activated regardless of
where was when it was previously
switched off.
Possible Reasons The Engine Does Not
Autostop
For higher comfort and increased safety,
and to reduce emissions, there are
certain conditions where the engine will
not autostop despite the system being
active, such as:
Engine still cold.
Especially cold outside temperature.
Battery not sufficiently charged.
Driver's door not shut.
Driver's seat belt not fastened.
Reverse gear engaged (e.g. for parking
maneuvers).
With the automatic climate control
active, an adequate cabin heating or
cooling comfort has not been reached or
with MAX-DEF function active.
During the first period of use, to
initialize the system.
Steering angle beyond threshold.
Engine Restarting Conditions
Due to comfort, emission control, and
safety reasons, the engine can restart
automatically without any action by the
driver, under special conditions, such as:
Battery not sufficiently charged.
Reduced braking system vacuum (e.g.
if the brake pedal is pressed repeatedly).
Vehicle moving (e.g. when driving on
roads with a grade).
Engine stopping by the Stop/Start
system for more than approx. three
minutes.
With the automatic climate control
active, an adjustment in cabin heating or
cooling is made or with MAX-DEF
function active.
Safety Functions
When the engine is stopped through the
Stop/Start system, if the driver releases
their seat belt, opens the driver's or
passenger's door, or opens the hood from
inside the vehicle, the engine can be
restarted only by using the ignition.
This condition is indicated to the driver
both through a buzzer and a message on
the instrument cluster display.
Energy Saving Function
If the driver does not carry out any action
for more than three minutes after the
automatic engine restart, the Start/Stop
system will switch off the engine in order
to prevent fuel consumption.
In this situation, the engine can only be
restarted using the ignition device.
Note: It is possible to keep the engine
running by deactivating the system.
Irregular Operation
In the event of malfunction, the
Stop/Start system is deactivated.
For failure indications, refer to "Warning
Lights and Messages" paragraph in
"Getting To Know Your Instrument Panel".
Vehicle Inactivity
In the event of vehicle inactivity (or if the
battery is replaced), special attention
must be paid to the disconnection of the
battery power supply.
Proceed as follows:
Remove connector from socket to
disconnect sensor (battery status
monitoring) installed on the negative pole
of the battery. This sensor should never
be disconnected from the pole except if
the battery is replaced.

STARTING AND OPERATING

The vehicle is equipped with an
Intelligent Battery Sensor (IBS), which is
able to measure the charge and discharge
voltage and calculate the charge level
and the general condition of the battery.
The sensor is placed next to the negative
terminal (-) of the battery.For a correct charge/discharge
procedure, the charge voltage must go
through the IBS sensor.
1. Turn the charger on and follow the
instructions on the user's manual to
completely recharge the battery.
2. When the battery is charged, turn the
charger off before disconnecting it from
the battery.
3. Disconnect the black cable terminal of
the battery charger and then the red
cable terminal.
4. Refit the protective cover of the
positive terminal of the battery and the
access cover to the battery
compartment.
Note:
If a "quick-type" battery charger is
used with the battery fitted on the
vehicle, before connecting it disconnect
both cables of the battery itself. Do not
use a "quick-type" battery charger to
provide the starting voltage.
