Gear shift indicator *
System which reduces fuel consumption by advising the driver to change up on vehicles fitted with a manual gearbox.
Operation
The system intervenes only when driving
economically.
Depending on the driving situation and your
vehicle's equipment, the system may advise
you to skip one or more gears. You can
follow this instruction without engaging the
intermediate gears.
The gear engagement recommendations must
not be considered compulsory. In fact, the
configuration of the road, the amount of traffic
and safety remain determining factors when
choosing the best gear. Therefore, the driver
remains responsible for deciding whether or not
to follow the advice given by the system.
This function cannot be deactivated.
* According to engine.
Example:
- You are in third gear.
- You press the accelerator pedal
moderately.
- The system may suggest that you engage a
higher gear, if appropriate.
The information appears in the instrument
panel in the form of an arrow accompanied by
the suggested gear.
In the case of driving which makes
particular demands on the performance
of the engine (firm pressure on the
accelerator pedal, for example, when
overtaking...), the system will not
recommend a gear change.
The system never suggests:
- engaging first gear,
- engaging reverse gear,
- engaging a lower gear.
