- With the engine running, depending on your preference place the lever on R, A or M.
- Check the position engaged on the rev counter.
- Release the handbrake.
- Release the brake pedal and accelerate.
If the lever is not in position N, the warning lamp "N" fl ashes on the rev counter.
If the brake pedal is not pressed down, the warning lamp "Foot on brake" fl ashes in the instrument panel.
In both cases, the engine does not start; recommence the above procedure.
Note: If the vehicle has been stationary for a long time, or if you have pressed the brake pedal a number of times while stationary, it will be necessary to press the brake pedal hard down in order to authorise the engine to start.
Stopping the engine
Before switching the engine off, you can choose:
- to leave the vehicle in neutral; for that, place the lever in position N,
- to leave the vehicle with a gear engaged (R, A or M); for that, place the lever in the position chosen. In this case, the vehicle cannot be moved.
In all cases, it is essential to apply the handbrake.
Before undertaking any operation in the engine compartment, make absolutely sure that the gearbox is in neutral and that the handbrake is on.
Do not hold the vehicle stationary using only the accelerator.
If you are stopped on an incline, use the handbrake to hold the vehicle.
Acceleration
To obtain optimum acceleration (for example to overtake another vehicle), you have only to press the pedal hard down to go beyond the end-of-travel switch.

Automated mode
Place the selection lever in position A.
"A" appears in the speedometer to confi rm the selection made.
The gearbox then operates in autoactive mode, without intervention on your part.
It constantly selects the gear best adapted to the following parameters:
- Style of driving.
- Road profi le.
Cancellation of automatic mode
Move the gear lever from position Ato select a different position.
The "A" warning lamp disappears on the rev counter.
Instant manual mode
Even in automatic mode, if you touch the controls under the steering wheel "+" or "-" you immediately change gear.

Manual mode
Position the gear lever in position M, then:
- push the lever to engage a higher gear,
- pull the lever to change down.
Manual mode with controls behind the steering wheel
Place the gear lever in position M, and then the controls at the steering wheel will give you access to the six gears in forward drive.
To change gear:
- Press behind the control "+" at the steering wheel to engage a higher gear.
- Press behind the control "-" at the steering wheel to change down.
Observations:
When the vehicle is braking or reducing speed, the gearbox changes down automatically to a suitable gear.
In manual mode, it is not necessary to release the accelerator during changes of gear.
Changes of gear are accepted only if consistent with engine speed.
Under heavy accelera-tion, a higher gear will only be engaged when the driver actions the gear lever or the controls at the steering wheel.
Note: These controls at the steering do not permit you to select neutral or reverse gear.

HILL START ASSIST (with 6-speed electronic gearbox system)
To aid starting on a gradient, your vehicle is equipped with a system that keeps it temporarily immobilised.
It keeps the brakes applied for a brief moment, precisely the time taken for moving your foot from the brake pedal to the accelerator pedal.
This function is only active when the vehicle is completely stationary, with your foot on the brake pedal, in particular conditions on a slope.
On a descending slope, provided the vehicle is stationary and reverse gear is engaged, the vehicle is held for a brief moment when you release the brake pedal.
Do not leave the vehicle during the hill start phase.
The hill start function cannot be deactivated.
On an ascending slope, with the vehicle stationary, the vehicle is held for a brief moment when you release the brake pedal, provided you are in A or M.
Display of these warning lamps indicates a malfunctioning of the hill start assist function.

- vehicle load.
In this way the gearbox operates in autoadaptive mode, without the need for your intervention.
For certain manoeuvres (for example overtaking), it is possible to ob tain maximum acceleration by pressing hard down on the accelerator pedal, which may trigger automatic changedown to a lower gear.
Note
During braking, the gearbox may kick down automatically in order to offer an effective engine brake.
If you rapidly lift your foot off the accelerator, the gearbox will guard your safety by not changing up again.
