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

F

R
eturn 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:
-

i
f you press the accelerator and
brake pedals at the same time,
-

i
f 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.

- t he towball is correctly locked in place (position A ),
-

t
he security key lock is on and the key removed; the locking wheel can no longer be
