Invalid value during manual
operation
This symbol is displayed if a gear
is not engaged correctly (selector
between two positions).
Stopping the vehicle
Before switching off the engine, put the selector
in position P or N to place the gearbox in
neutral.
In both cases, apply the parking brake to
immobilise the vehicle, unless it is programmed
to automatic mode.
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, there is an
audible signal and a message appears.
F Return the selector to position P;
the audible signal stops and the
message disappears.
Operating fault
When the ignition is on, a message appears
in the instrument panel screen to indicate 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.
Have it checked by a CITROËN dealer or a
qualified workshop.
You risk damaging the gearbox:
- if you press the accelerator and
brake pedals at the same time,
- if you force the selector from
position P to another position when
the battery is flat.
To reduce fuel consumption when
stationary for long periods with the
engine running (traffic jam...), position
the gear selector at N and apply the
parking brake, unless it is programmed
in automatic mode.
