Traffic and road conditions
High fuel consumption is caused
by heavy traffic, for instance when
travelling in a queue with frequent use of
low gears or in cities with many traffic
lights. Winding mountain roads and rough
road surfaces also adversely affect
consumption.
Stops in traffic
During prolonged hold-ups (e.g. level
crossings) switch off the engine.
BRAKES
108)
In order to guarantee the maximum
braking capacity for the first use, Alfa
Romeo performs a "run-in" procedure for
discs and pads directly at the factory.
The use of carbon-ceramic material
brake discs guarantees braking features
(better deceleration/pedal load ratio,
braking distances, fading resistance)
proportional to the dynamic features
of the car in addition to considerably
decreasing the unsprung component
weight.
The materials used and the structural
features of the system could generate
anomalous noises which have absolutely
no adverse effect on correct operation
and reliability of the braking system.
Greater pressure may need to be applied
to the brake pedal the first time to keep
the same braking capacity in presence
116
of condensation or salt on the braking
surfaces, for example after washing or if
the car is not used for a long time.
WARNING Given the high technological
level of this system, any servicing on it
must be performed by a Dedicated Alfa
Romeo Dealership with the exclusive
skills needed for the repair operations.
WARNING In case of intensive, high-
performance use of the car, have the
condition of the carbon-ceramic material
braking system inspected at a Dedicated
Alfa Romeo Dealership, as shown on the
Service Schedule.
Overheating of the brakes
The braking system components may
overheat when driving on mountain roads
with steep gradients or during sporty use
of the car. When this happens, there may
be noise/vibrations while braking.
When you reach the destination, do not
stop the engine immediately, but leave it
idling for a few minutes to let the braking
system components cool down and to
lubricate the engine parts properly.
To make the car safe when it is parked,
apply the safety provisions of the
Highway Code before leaving the car:
engage P (Park) mode;
position the wheels at full lock;
engage the electric parking brake;
when parked on a steep slope, place
chocks or stones behind the wheels.
DRIVING ON RACE TRACKS
Before driving on a track using a racing
style, it is necessary to:
attend a race track driving course;
check the liquid levels in the engine
compartment. For more information, see
the "Checking levels" paragraph in the
"Maintenance and care" chapter;
have the car inspected at a Dedicated
Alfa Romeo Dealership.
Remember that the car was not designed
to be driven exclusive on the race track
and that this use increases stress and
component wear.
Preheating the carbon ceramic breaks
The brake discs must be warmed up
to make them fully efficient. You are
advised to perform the following
procedure:
brake nine times from 80 mph
(130 km/h) to 20 mph (30 km/h) with
deceleration equal to 0.7 g (the
longitudinal acceleration value is shown
on the instrument panel display by
setting RACE mode and selecting the
"Performance" page) with 20 second
intervals between brake applications;
keep the car at a speed comprised
between 37 mph (60 km/h) and 60 mph
(100 km/h) and do not brake for 240
