Driving
Forward drive
F Press control D.
The indicator lamp in the control comes on.
D and the gear engaged appear in
the instrument panel.
The gearbox then operates in auto-adaptive
mode, without any action on the part of the
driver. It continuously selects the most suitable
gear taking account of:
- optimisation of fuel consumption,
- driving style,
- road conditions,
- vehicle load.
For optimum acceleration, when
overtaking another vehicle for example,
press the accelerator pedal fully down,
beyond the point of resistance.
Never select neutral (position N) when
moving.
Do not press the brake and accelerator
pedals at the same time: this could
cause very rapid wear of the clutch.

Temporary control of gear
changing
You can temporarily take over control of gear
changes using the steering mounted "+" and
"-" control paddles: if the engine speed allows,
the gear change is carried out.
This function allows you to anticipate certain
situations such as overtaking another vehicle or
approaching a bend.
After a few moments without any action on the
paddles, the gearbox resumes control of gear
changing automatically.
Reverse
To engage reverse, the vehicle must be
immobilised with your foot on the brake.
F Press control R.
The indicator lamp in the control comes on.
There is an audible signal on
engagement of reverse.
If reverse gear is requested when moving,
the N warning lamp flashes and the gearbox
goes into neutral automatically.
To engage reverse, stop the vehicle then, with
your foot on the brake pedal, press control N,
then R.
