KNOWING THE INSTRUMENT PANEL

IMPORTANT
6) If thewarning light switches on when driving, stop the engine immediately and contact the dedicated Alfa
Romeo Dealership.
WARNING
62) Deteriorated engine oil should be replaced as soon as possible after the digital warning light comes on, and never
more than 500 km after it first switches on. Failure to observe the above indications may result in severe damage to
the engine and invalidate the warranty. Remember that when the digital warning light comes on, it does not mean
that the level of engine oil is low, so if it flashes you must not top up the engine oil.
63) If the warning light flashes with the car in motion, contact the dedicated Alfa Romeo Dealership.

SBR SYSTEM (Seat
Belt Reminder)
IN BRIEF
This system comprises an acoustic
warning which, in conjunction with
the
warning light flashing on the
instrument panel, advises the driver if
their seat belt has not been fastened.
Contact the dedicated Alfa Romeo
Dealership to deactivate this acoustic
warning permanently.
The acoustic warning can be
reactivated at any time through the
Setup Menu (see "Menu Options"
paragraph in “Knowing the
instrument panel” section).
If the driver side seat belt is not
fastened, when 20 km/h is exceeded or
when travelling at a speed from 10 to
20 km/h for longer than 5 seconds, an
acoustic signal sequence will be started
(continuous acoustic signal for the first
6 seconds followed by 90 seconds
of intermittent beeping) and the
warning light will flash.The warning light will stay on constantly
at the end of the cycle until the engine
is stopped. The acoustic signal is
interrupted immediately when the seat
belt is fastened.
If the seat belt is unfastened again
when driving the car, the acoustic signal
and the flashing warning light resume
as described previously.
PRETENSIONERS
The car is equipped with seat belt
pretensioners, which draw back the
seat belts by several centimetres in the
event of a strong frontal impact. This
guarantees the perfect adherence
of the seat belts to the occupant's
bodies before the retention action
begins.
It is evident that the pretensioners have
operated when the belt withdraws
toward the retractor.
This car is also equipped with a second
pretensioner (in the kick plate area). Its
activation is signalled by the shortening
of the metal cable.
A slight discharge of smoke may be
produced during the activation of the
pretensioner which is not in harmful and
does not involve any fire hazard.
IMPORTANT To obtain the highest
degree of protection from the action of
the pretensioner, wear the seat belt
tight to the chest and pelvis.

SAFETY

Passenger front airbag
This is located in a dedicated
compartment in the dashboard fig. 72.
74)
GENERAL WARNINGS
The front airbags may activate in the
event of sharp impacts to the
underbody of the car (e.g. impact with
steps, pavements, potholes or road
bumps, etc.).
When the airbag deploys it emits a
small amount of dust: the dust is
harmless and does not indicate the
beginning of a fire. The dust may irritate
the skin and eyes however: in this
case, wash with neutral soap
and water.
Airbag checking, repair and
replacement must be carried out at a
dedicated Alfa Romeo Dealership.If the car is scrapped, have the airbag
system deactivated at a dedicated
Alfa Romeo Dealership.
Pretensioners and airbags are deployed
according to different logics on the
basis of the type of collision. Failure to
deploy of one of the devices does
not necessarily indicate a system
malfunction.
77) 78) 79) 80) 81) 82) 83)
WARNING
72) Do not apply stickers or other
objects to the steering wheel or
the passenger side airbag cover.
Do not place objects on the
passenger side of the dashboard
because these could interfere
with the correct opening of the
passenger airbag and cause injury
to occupants.
73) Always drive keeping your hands
on the steering wheel rim so that
the airbag can inflate freely if
necessary. Do not drive with your
body bent forward. Keep the
backrest in straight position,
resting correctly your back on it.74) Instructions to deactivate the
passenger's front airbag can be
found in the "Menu Options"
paragraph of the "Knowing the
instrument panel" chapter. Please
note that under these conditions
the airbag will NOT deploy in case
of need (accident).
75) Do not rest your head, arms or
elbows on the door to prevent
injury during airbag deployment.
76) Never lean your head, arms and
elbows out of the window.
77) If the
warning light does not
switch on when the key is turned
to MAR-ON, or stays on while
driving (on some versions
together with a message on the
display) there may be a fault in the
restraint systems. In this case,
airbags or pretensioners may not
be activated in the case of an
accident or (in a lesser number of
cases) they may be activated
incorrectly. Before proceeding,
contact a dedicated Alfa Romeo
Dealership to have the system
checked immediately.
78) Do not travel carrying objects on
your lap, in front of your chest or
between your lips (pipe, pencils,
etc.): they could cause severe
injury if the airbag is deployed.

SAFETY

79) If the car has been subject to
theft, attempted theft, vandalism,
or flooding, have the airbag
system inspected at a dedicated
Alfa Romeo Dealership.
80) The airbags may also be
deployed when the car is not
moving, if the key is inserted and
turned to MAR-ON even when
the engine is off, if the car is hit by
another moving vehicle. Also
remember that no safety device
(airbags or pretensioners) will
activate in the event of impact
when the key is at STOP.
Non-deployment of these devices
under these circumstances does
not therefore indicate a system
malfunction.
81) When the ignition key is turned
to MAR-ON, the
warning light
comes on constantly for the first 4
seconds. Then, if the warning
light remains on, this means the
passenger's protection has been
deactivated; if the warning light
switches off, instead, the
passenger's protection is enabled.
82) The front airbag is designed
to be deployed for impacts of
a greater intensity than for the
pretensioners. For impacts whose
intensity falls between the two
levels, normally, only the
pretensioners will be activated.83) The airbag does not replace seat
belts but increases their
effectiveness. Because front
airbags are not deployed for
low-speed frontal impacts, side
collisions, rear shunts or rollovers,
occupants are protected only by
their seat belts, which must
always be fastened.
