In this event, stability must be assured by thedriver by repeating alternate "pull-release" actions on the control lever A.

In the event of a failure of the main servicebrake or in an exceptional situation (e.g. driver
taken ill, under instruction, etc) a continuous

With the ignition on, the flashing of AUTO
,
accompanied by an audible signal and amessage in the screen, indicates a malfunction
of the gearbox.
Have it checked by a CITROËN dealer or a qualified workshop.
When immobilising the vehicle, withthe engine running, you must place thegear lever in neutral N
. Before carrying out any work in the engine compar tment, ensure that thegear lever is in neutral N
and that the parking brake is applied. Whatever the circumstances, you mustmanually apply the parking brake whenparking, unless the parking brake is programmed in automatic mode. Be
fore switching off the engine, you can:

not be possible to move the vehicle.
To engage reverse gear R, the vehicle must be
immobilised with your foot on the brake pedal. )Select position R.

At low high speed, if reverse gear is requested,
the N indicator flashes and the gearbox goes
into neutral automatically. To engage reverse, put the gear lever in position N , then position R.
In both cases, you must apply the parkingbraketo immobilise the vehicle.
Reverse

Engagement of reverse gear is accompanied by an audible signal.

Invalid value during manualoperation

In both cases, apply the parking brake toimmobilise the vehicle, unless it is programmedto automatic mode.

If the lever is not in position P, when thePdriver's door is opened or approximately45 seconds after the ignition is switched off, there is an audible signal and amessage appears.)Return the lever to position P
; the audible signal stops and themessage disappears.


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 malfunction.
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 Pto R
and from N
to R
. This will not cause any
damage to the gearbox.
Do not exceed 60 mph (10 0 km/h), local speed restrictions permitting.
Have it checked by a CITROËN dealer or aqualified workshop.
This warning lamp may also come on if a door
is opened.
You risk damaging the gearbox:


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

- if you force the lever from position Pto another position when the batteryis flat.

To reduce fuel consumption when stationary for long periods with the engine running (traffic jam...), positionthe gear lever at Nand apply theparking brake, unless it is programmed in automatic mode.
