SYSTEM AVAILABILITY
External factors and conditions may
affect the proper operation of TJA.
The main ones are listed below:
narrow, winding and curvy streets;
poor visibility (due to heavy rain, snow,
fog, etc.);
front lights of incoming cars or direct
sunlight or shade;
damage or obstructions caused by
mud, ice, snow, etc.
bumper damaged or not aligned;
interference with other equipment
that causes electromagnetic waves;
presence of roadworks/road
construction sites;
if the indications given by the
navigation system (if any) of the Connect
system are not yet ready and/or if the
navigation system is recalculating the
route.
SYSTEM LIMITED OPERATION
The TJA may have limited or reduced
functionality when one of the following
conditions occurs:
The main ones are listed below:
lane marking lines are not clear or in
conditions of poor visibility (e.g. in heavy
rain, snow, fog, etc.);
either the camera or radar are
damaged, covered or obstructed (e.g. by
mud, ice, snow, etc.);
180
when driving in the hills or on roads
with narrow turns;
near motorway tollgates;
when the motorway entrance or exit is
more than 6 meters wide;
if the camera is exposed to dazzling
light (e.g. reflection or direct sunlight).
WARNING
150) Many unpredictable situations can
arise, affecting the performance of the TJA
system. The driver must be ready to react
immediately and take control of the car in
place of the TJA system.
151) If the car approaches a bend that is
too tight with respect to the current speed,
the TJA system turns off. The driver must
therefore be ready to immediately regain
control of the car at any time. To avoid this
situation it is important that the car speed
set does not exceed the current road speed
limit.
152) The TJA system uses a hands on
steering wheel detection sensor: the driver
must keep his hands on the steering wheel
at all times. If the hands are removed from
the steering wheel for a certain period of
time, the system disengages and the ACC
turns off.
153) When using the TJA system, hold
the steering wheel and consider the
road conditions and surrounding traffic.
The driver must therefore be ready to
immediately regain control of the car at any
time. Failure to observe these instructions
can cause severe injuries with even lethal
consequences.
154) The TJA system is an aid for the driver,
who must always pay full attention while
driving. The responsibility always rests
with the driver, who must take into account
the traffic conditions in order to drive in
complete safety. The driver must always
maintain a safe distance from the vehicle in
front.
155) If the windscreen must be replaced due
to scratches, chipping or breakage, contact
exclusively an Alfa Romeo Dealership. Do
not replace the windscreen on your own, risk
of malfunction! It is advisable to replace the
windscreen if it is damaged in the area of
the camera.
156) Driving the car on urban routes could
significantly change the sensitivity of the
system, due to the limited and/or lack
of vertical and horizontal signage and
variable traffic conditions. Therefore, it is
recommended not to use the TJA system
when driving in city streets.
157) Do not place any objects on the
steering wheel (e.g. steering wheel covers of
any type or material) which could interfere
with the capacitive hand detection sensor
on the steering wheel.
