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.

Drive
The gearbox always selects the gear best adapted to the following parameters:

- 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.
