Gear efficiency indicator

(Depending on engine.)
This system reduces fuel consumption by
recommending the most appropriate gear.
Operation
Depending on the driving situation and your
vehicle's equipment, the system may advise
you to skip one or more gears.
Gear engagement recommendations are
only optional. In fact, the configuration of the
road, the traffic density and safety remain
determining factors when choosing the best
gear. Therefore, the driver remains responsible
for deciding whether or not to follow the
system's advice.
This function cannot be deactivated.
With an automatic gearbox, the system is
only active in manual operation.
The information appears in the
instrument panel in the form of an
arrow and the recommended gear.
The system adapts its gear shift
recommendation according to the driving
conditions (slope, load, etc.) and the
driver's requirements (power, acceleration,
braking, etc.).
The system never suggests:
- engaging first gear,
- engaging reverse.
Stop & Start
The Stop & Start function puts the engine
temporarily into standby – STOP mode – during
phases when the vehicle is stopped (red lights,
queues, etc.). The engine restarts automatically
– START mode – as soon as the driver wishes
to move off again.
Primarily designed for urban use, the function
is intended to reduce fuel consumption and
exhaust emissions as well as the noise level
when stationary.
The function does not affect the functionalities
of the vehicle, in particular the braking.
