between two positions).

Stopping the vehicle
Before switching off the engine, you can
engage position P or N to place the gearbox in
neutral.
In both cases, apply the parking brake to
immobilise the vehicle.
If the selector is not in position P,
when the driver's door is opened or
approximately 45 seconds after the
ignition is switched off, a warning
message appears in the screen.
F Return the selector to position P;
the message disappears.
When driving on flooded roads or when
crossing a ford, proceed at walking
pace.
Operating fault
When the ignition is on, the lighting
of this warning lamp, accompanied
by an audible signal and a message in the
multifunction screen, indicates a gearbox fault.
In this case, the gearbox switches to back-up
mode and is locked in 3rd gear. You may feel
a substantial knock when changing from P
to R and from N to R. This will not cause any
damage to the gearbox.
Do not exceed 60 mph (100 km/h), local speed
restrictions permitting.
Contact a CITROËN dealer or a qualified
workshop as soon as possible.
There is a risk of damage to the
gearbox:
- if you press the accelerator and
brake pedals at the same time,
- if you force the movement of the
selector from the P position to
another position when the battery
is flat.
To reduce fuel consumption when at
a prolonged standstill with the engine
running (traffic jam, etc.), put the
selector in the N position and apply the
parking brake.
