Malfunction
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.
If a fault in the system occurs, these warning
lamps come on.
Contact a CITROËN dealer or a qualified
workshop to have the system checked.
The system adapts its gear shift
recommendation according to the driving
conditions (slope, load, etc.) and the
driver's requirements (power, acceleration,
braking, etc.).

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.
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.
Downhill, with the vehicle stationary and
reverse gear engaged, the vehicle is held for
a short time when you release the brake pedal.
This function cannot be deactivated.
The function does not affect the functionalities
of the vehicle, in particular the braking.
