safety in low-grip driving conditions. It is
advisable to select "All Weather" mode
in the presence of low-grip road
surfaces.
"ELECTRONIC Q2" SYSTEM: the
system is deactivated.
Engine and gearbox/transmission:
standard response.
Deactivation
To deactivate “All Weather” mode and
return to “Natural”, move lever A
fig. 47 upwards (to letter “d”) and keep
it in this position for half a second.
IMPORTANT
During the first 250 km of usage of
the car, the Dynamic and Race modes
are inhibited. Within this first interval of
start-up mileage it is advisable to refrain
from an aggressive driving style, so that
the best gear shifting quality can be
achieved over time.
When the engine is next started, the
"All Weather" or "Dynamic" mode
selected previously is retained. The
system will reactivate in "All Weather" or
"Dynamic" mode, depending on which
mode was selected before the engine
was switched off.
When the engine is next started, the
"Race" mode selected previously is not
retained. The system will reactivate in
"Dynamic" mode.
It is not possible to go directly from
“Dynamic” mode to “All Weather” modeand vice versa. You must always first go
back to “Natural” mode and then select
the other mode.
System failure
In the event of system failure or a fault
with lever A fig. 47, no driving modes
can be selected.
The display will become grey (same
screen as "Natural" mode) but without
an indication of the Alfa DNA setting.
The display will also show a warning
message.
EOBD SYSTEM
(European On
Board Diagnosis)
Operation
The EOBD system (European On Board
Diagnosis) carries out a continuous
diagnosis of the components of the car
related to emissions.
It also alerts the driver, by switching on
the
warning light on the instrument
panel, together with a message on the
display, when these components are no
longer in peak condition (see “Warning
lights and messages” paragraph in the
"Knowing the instrument panel"
chapter).
The aim of the EOBD system (European
On Board Diagnosis) is to:
monitor the efficiency of the system;
indicate an increase in emissions;
indicate the need to replace
deteriorated components.
The car also has a connector, which
can interface with appropriate tools,
that makes it possible to read the error
codes stored in the electronic control
units together with a series of specific
parameters for engine operation and
diagnosis. This check can also be
carried out by the traffic control
authorities.
IMPORTANT After eliminating a fault, to
check the system completely, the
