auxiliary battery and the traditional lead
battery. When the accelerator pedal
is released with the gear is engaged,
the BSG acts as an engine brake (e-
COASTING function). This contribution
is increased by pressing the brake
pedal at the same time (e-BRAKING
function). The recovered energy is
made available later, helping to save
fuel.
ECO FUNCTION
HYBRID SYSTEM
(for versions/markets, where provided)
To activate the function press the ECO
button fig. 117.
Your car is provided with a hybrid
system, which uses an electric motor
that is mechanically coupled to the
thermal engine (via a dedicated belt)
and powered by an auxiliary lithium
battery (12 V). The electric motor
contributes to driving the car forward
together with the heat engine when
there is a certain acceleration request,
and charges the lithium battery when
the car decelerates.
NOTE If the conventional battery is
flat, there is no energy recovery to
the auxiliary battery, and so the Trip
Computer "Energy Flows" screen on
the instrument panel (for versions with
colour display only) does not display
the relative recharging flows.

When the ECO function is active,
the vehicle is set for a driving style
characterised by reduced fuel
consumption. When the function is
active, the corresponding LED on the
button switches on.
The hybrid system uses a BSG (Belt
Starter Generator) electric motor
working both as a generator (alternator)
and as a starter motor.
ACCELERATION ASSIST
FUNCTION ("e-ASSIST"
function)
In general, during pickup from low
engine speeds, the hybrid system
shares the torque between the electric
motor and thermal engine when
necessary, thereby reducing the output
power of the thermal engine in order to
optimise consumption.
NOTE The system does not operate
continuously, but is activated according
to the car status, driving conditions
(acceleration, braking, deceleration
and starting) and road conditions (e.g.
gradient).
The function is automatically
reactivated at every start. Press the
ECO button again to deactivate the
function and restore the normal driving
setting.
