START & STOP EVO
The Start & Stop Evo system
automatically stops the engine each time
the vehicle is stationary and starts it
again when the driver wants to move off.
In this way, the vehicle efficiency is
increased, by reducing consumption,
dangerous gas emissions and sound
pollution.
OPERATING MODE
Stopping the engine

With the vehicle stopped, the engine
stops with gearbox in neutral and clutch
pedal released.
Versions with automatic transmission
With vehicle at a standstill and brake
pedal pressed, the engine switches off if
the gear lever is in a position other than
R.
The system does not operate when the
gear lever is in R, for making parking
manoeuvres easier.
In the event of stops uphill, engine
switching off is disabled to make the "Hill
Start Assist" function available (works
only with running engine).
NOTE The engine can only be
automatically stopped after having run atabout 6 mph (10 km/h). After an
automatic restart, to stop the engine you
only need to move the vehicle (exceed a

LANE DEPARTURE WARNING
(LDW) SYSTEM
DESCRIPTION
41) 42) 43) 44) 45) 46)
The Lane Departure Warning system
makes use of a camera located on the
windscreen to detect the lane limits and
calculate the position of the vehicle
within such limits, in order to make sure
that it remains inside the lane.
When one or both lane limits are
detected and the vehicle passes over one
without the driver's say-so (direction
indicator not turned on), the system
emits an acoustic signal.
If the vehicle continues to go beyond the
line of the lane without any intervention
from the driver, the surpassed line will
light up on the display (left or right) to
urge the driver to bring the vehicle back
into the limits of the lane.
SYSTEM ACTIVATION/DEACTIVATION
The system is activated/deactivated by
pressing the button, fig. 113
When the engine is started the system is
always activated.Activation conditions
Once switched on, the system becomes
active only if the following conditions are
met:
the vehicle speed is above 45 mph
(70 km/h);
the lane limit lines are visible at least
on one side;
there are suitable visibility conditions;
the road is straight or with wide radius
bends;
a suitable distance is kept from the
vehicle in front;
the direction indicator (for leaving the
lane) is not active.
IMPORTANT
41)Projecting loads on the roof of the
vehicle may interfere with the correct
operation of the camera. Before starting
