Alfa Romeo Tonale Owner's Handbook Manual page 171

If the vehicle shown on the instrument
panel display is travelling in the same
lane at a lower speed, a dedicated
symbol is shown on the display on some
versions. The device will automatically
adjust the car's speed to maintain the set
distance, independently of the set speed.
The car holds the set distance until:
the vehicle ahead accelerates to a
speed higher than the set speed
the vehicle ahead leaves the lane
or the detection field of the Adaptive
Cruise Control device sensor
the distance setting is changed
the Adaptive Cruise Control device is
deactivated/cancelled
WARNING The maximum braking applied
by the device is limited. The driver may
apply the brakes in all cases if needed.
WARNING If the system predicts that
the braking level is insufficient to
maintain the set distance, it signals the
driver to pay attention when approaching
the vehicle ahead by displaying an alert
message on the display. An acoustic
warning is also emitted. In this case, it
is advisable to brake immediately as
necessary to hold a safe distance from
the vehicle ahead.
WARNING The driver is responsible for
ensuring that there are no pedestrians,
other cars or objectives along the
direction of the car. Failure to comply
with these precautions may cause
serious accidents and injuries.
WARNING The driver is fully responsible
for holding a safe distance from the
vehicle ahead respecting the highway
code in force in the respective country.
OVERTAKING AID FUNCTION
154)
The Adaptive Cruise Control system,
when traffic conditions permit, allows
additional acceleration to be given to the
vehicle to facilitate overtaking by simply
activating the direction indicator.
This additional acceleration is provided
as long as the distance to the vehicle to
be overtaken is guaranteed.
Once acceleration is perceived, the
driver must make sure that the traffic
and cars coming from behind allow it, and
to make the lane change manoeuvre.
Once the trajectory is clear of vehicles,
Adaptive Cruise Control will regain
control of the selected speed, or reduce
it to maintain the desired distance from
the vehicle ahead.
NOTE The overtaking aid function is only
available on the side where overtaking is
permitted according to the highway code
(left in countries with traffic on the right
side of the carriageway, right in countries
with traffic on the left side).
SPEED REDUCTION ON BENDS
The Adaptive Cruise Control system can
decelerate slightly on bends to improve
car stability and comfort.
The functionality can be a valuable aid
when driving around a roundabout
or with gradual curves, approached
with increasing curvature. The system
is unable to compensate for sudden
steering or, in general, medium to high
lateral acceleration.
However, it is the driver's responsibility,
depending on traffic conditions, to apply
the brake pedal where necessary to
further reduce speed, ensuring stability
in sharp or decreasing radius bends.
DEACTIVATION
The device is deactivated and the set
speed is cancelled if:
push the button (1) fig. 166
the ignition device is set to STOP
the device is cancelled:
by pressing the CANC button (or
RES/CANC, where provided)
when the conditions indicated in the
paragraph "Setting the desired speed"
occur
when the radar on the front bumper is
unavailable
when reaching very steep slopes
If these conditions occur while the
system is decelerating with respect to a
