Manual operation
Ddisappears and the gears engaged appear in succession on the
instrument panel.
If the en
gine speed is too low or
too high, the gear selected flashes for a fewseconds, then the actual gear engaged isdisplayed.
It is possible to change from position D(automatic) to position M
(manual) at any time.
When the vehicle is stationary or moving
ver
y slowly, the gearbox selects gear M1automatically.
The spor t and snow programmes do not
operate in manual mode.
Invalid value during manualoperation
)Select position M for sequential
changing
of the four gears. )Push the lever towards the + sign
to change up a gear.)Pull the lever towards the - sign to changedown a gear.
It is only possible to change from one gear to
another if the vehicle speed and engine speedpermit; other wise, the gearbox will operate
temporarily in automatic mode. This s
ymbol is displayed if a gear
is not engaged correctly (selector
between two positions).
Stopping the vehicle
Before switching off the engine, you can
engage position Por Nto place the gearbox inneutral.
In both cases, apply the parking brake to
immobilise the vehicle. When the i
gnition 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 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.
Contact a CITROËN dealer or a qualified
wor
kshop as soon as possible.

Operating fault
If the lever is not in position P,P
when the driver's door is opened or approximately 45 seconds after the ignition is switched off, a message appears in the multifunction screen. )Return the lever to position P
; the message disappears.

There is a risk of damage to thegearbox:


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

- if you force the movement of the gear lever from the Pposition to another position when the battery is flat.
To r e d u c e fuel consumption when at a prolonged standstill with the enginerunning (traffic jam...), put the gear lever in the Nposition and apply the parking brake.

Stop & Start The Stop & Start system puts the engine temporarily into standby - STOP mode - during stops in the traffic (red lights, traffic jams, or other...).
The engine restar ts automatically - START mode - as soon as you want to move off. The restar t takes place instantly, quickly and silently.
Per
fect for urban use, the Stop & Start system reduces fuel consumption and exhaust emissions as well as the noise level when stationary.
Operation
Going into engine STOP mode
For your comfor t, during parkingmanoeuvres, STOP mode is not available for a few seconds after coming out of reverse gear.STOP mode does not affect the functionality of the vehicle, such as for example, braking, power steering...
Never refuel with the engine in STOPmode; you must switch off the ignition with the key. Th
e "ECO"warning lamp comes
on in the instrument panel and the engine goes into standby:
- with a manual gearbox
, at speeds below
12 mph (20 km/h), when you put the gear lever into neutral, and you release theclutch pedal. -with a 5 or 6-speed electronic gearbox ,
at speeds below 5 mph (8 km/h), when you press the brake pedal or put the gear lever in position N.
A time counter calculates the sum
of the periods in STOP mode
during a journey. It rests itself
to zero every time the ignition is switched on with the key.
STOP mode is not invoked when:


- the driver's door is open,

- the driver's seat belt is not fastened,

- the vehicle has not exceeded 6 mph(10 km/h) since the last engine star t using
the key,

- the engine is needed to maintain acomfortable temperature in the passenger compartment,

- demisting is active,

- some special conditions (battery charge, engine temperature, braking assistance,ambient temperature...) where the engine isneeded to assure control of a system.


Special cases: STOP mode not available

The "ECO"warning lamp flashes for
a few seconds then goes off.
This operation is per fectly normal.

- you unfasten the driver's seat belt,
- the speed of the vehicle exceeds 7 mph
(11 k m/h) with the electronic gearbox system,
- some special conditions (battery charge,engine temperature, braking assistance,
ambient temperature...) where the engine
is needed for control of a system.
Th
e "ECO"
warning lamp flashes for
a few seconds, then goes off.
This operation is per fectly normal.
With a manual gearbox in STOP mode,if you engage a gear without fully depressing the clutch pedal, a message is displayed asking you to fully depressthe clutch pedal so that the engine can restart.

The system is reactivated automaticallyat every new star t using the key.
Reactivation
This system requires a battery with a specialspecification and technology (reference numbers available from a CITROËN dealer
or a qualified workshop).
Fitting a battery not listed by CITROËN introduces the risk of malfunction of
the system. In the event of a fault with the system, the
"ECO OFF"
switch warning lamp flashes thencomes on continuously.
Have it checked by a CITROËN dealer or aqualified workshop.
In the event of a fault in STOP mode, the
vehicle may stall. All of the instrument panel
warning lamps come on. It is then necessaryto switch off the ignition and star t the engine
again using the key.


Operating fault
Maintenance


Before doing anything under the bonnet, deactivate the Stop & Start system to avoid any risk of injury resulting from automatic operation of STA R T mode.


The Stop & Start system makes use of advanced technology. All work
on this type of battery must be doneby a CITROËN dealer or a qualifiedworkshop. Pr
ess the "ECO OFF"switch again.
The system is active again; this is confirmed
by the switch warning lamp going off,accompanied by a message in the screen.
