KNOWING THE INSTRUMENT PANEL

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

9) When the engine is off, do not
leave the ignition key turned to
MAR-ON to prevent unnecessary
electrical consumption from
draining the battery.
10) A quick burst on the accelerator
before turning off the engine
serves absolutely no practical
purpose; it wastes fuel and is
especially damaging to
turbocharged engines.PARKING
Always remove the ignition key when
leaving the car.
When parking and leaving the car,
proceed as follows:
❒engage a gear (first gear if parked
uphill or reverse if facing downhill)
and leave the wheels turned;
❒stop the engine and engage the
handbrake.
Block the wheels with a wedge or a
stone if the car is parked on a steep
slope.
Wait until the indication of the gear
engaged disappears on the display
before releasing the brake pedal.
87)
IMPORTANT:NEVERleave the car with
the gearbox in neutral.
HANDBRAKE
To engage it, pull lever A fig. 73
upwards until the car is secured. When
the handbrake is engaged and the
ignition key is at MAR-ON, the
warning light will switch on in the
instrument panel.
To release the handbrake, raise lever A
slightly, hold down button B and lower
the lever. The
warning light in the
instrument panel will switch off.Four or five clicks are generally enough
when the car is on level ground, while
ten or eleven may be required if the car
is on a steep slope and laden.
88)
IMPORTANT Carry out these
manoeuvres with the brake pedal
pressed.
WARNING
87) Never leave children unattended
in the car. Always remove the key
from the ignition device when
leaving the car and take it with
you.
