On sharp acceleration, the gear-
box will not change up unless the
driver acts on the gear lever or
the steering mounted paddles.
Never select neutral N
while the
vehicle is moving.
Only engage reverse gear R
when the vehicle is immobilised
with the brake pedal pressed.
Manual gear changing
This selective gear change mode en-
ables you to overtake, for example, while
still remaining in automatic mode.
)
Operate the +
or -
steering mounted
control paddle.
The gearbox engages the gear request-
ed if the engine speed permits. AUTO
is
still displayed in the instrument panel.
After a few moments without any action
on the controls, the gearbox resumes
automatic control of the gears.
At very low speed, if reverse
gear is requested, this will only
be taken into account when the
vehicle is immobilised. The Foot
on brake
warning lamp may
fl ash in the instrument panel to
prompt you to brake.
Stopping the vehicle
Before switching off the engine, you
can choose to:
- move to position N
to engage neutral,
- leave the gear engaged; in this
case, it will not be possible to move
the vehicle.
In both cases, you must apply the park-
ing brake to immobilise the vehicle.
When immobilising the vehicle,
with the engine running, you
must place the gear lever in neu-
tral N
.
Before carrying out any work in
the engine compartment, check
that the gear lever is in neutral N
and that the parking brake is ap-
plied.
Operating fault
With the ignition on, the fl ashing of
AUTO
, accompanied by an audible sig-
nal and a message in the multifunction
screen, indicates a malfunction of the
gearbox.
Have it checked by a CITROËN dealer
or a qualifi ed workshop.
You must press the brake pedal
when starting the engine.
Whatever the circumstances,
you must manually apply the
parking brake when parking,
unless the parking brake is pro-
grammed in automatic mode.
Manual mode

lect position M
to change to manual
mode.
AUTO
disappears and the
gears engaged appear in suc-
cession in the instrument panel
screen.
The gear change requests are only car-
ried out if the engine speed permits.
It is not necessary to release the accel-
erator during gear changes.
When braking or slowing down, the
gearbox changes down automatically
to allow the vehicle to accelerate in the
correct gear.

Manual operation
)
Select position M
for sequential
changing of the six gears.
)
Push the lever towards the +
sign to
change up a gear.
)
Pull the lever towards the -
sign to
change down a gear.
It is only possible to change from one
gear to another if the vehicle speed and
engine speed permit; otherwise, the
gearbox will operate temporarily in au-
tomatic mode.
D
disappears and the gears
engaged appear in succes-
sion in the instrument panel.
If the engine speed is too low
or too high, the gear selected
fl ashes for a few seconds, then the ac-
tual gear engaged is displayed.
It is possible to change from position D
(automatic) to position M
(manual) at
any time.
When the vehicle is stationary or moving
very slowly, the gearbox selects gear M1
automatically.
The sport and snow programmes do
not operate in manual mode.
Invalid value during manual
operation
This symbol is displayed if a
gear is not engaged correctly
(selector between two posi-
tions).
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, unless it is
programmed to automatic mode.
If the lever is not in position P
,
when the driver's door is opened
or approximately 45 seconds af-
ter the ignition is switched off,
there is an audible signal and a
message appears.
)
Return the lever to position P
;
the audible signal stops and
the message disappears.
You risk damaging the gearbox:
- if you press the accelerator
and brake pedals at the same
time,
- if you force the lever from po-
sition P
to another position
when the battery is fl at. 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 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 qualifi ed workshop.
This warning lamp may also come on if
a door is opened.
Operating fault
To reduce fuel consumption
when stationary for long periods
with the engine running (traffi c
jam...), position the gear lever at
N
and apply the parking brake,
unless it is programmed in auto-
matic mode.

HILL START ASSIST
System which keeps your vehicle im-
mobilised temporarily (approximately
2 seconds) when starting on a gradi-
ent, the time it takes to move your foot
from the brake pedal to the accelerator
pedal.
This function is only active when:
- the vehicle is completely stationary,
with your foot on the brake pedal,
- when certain conditions of gradient
are met,
- with the driver’s door closed.
The hill start assist function cannot be
deactivated.
On an ascending slope, with the ve-
hicle stationary, the vehicle is held
for a brief moment when you release
the brake pedal:
- provided you are in fi rst gear or neu-
tral with a manual gearbox,
- provided you are in position A
or M
with the electronic gearbox system,
- provided you are in position D
or M
with an automatic gearbox.
Operation
Do not leave the vehicle while it
is being held in the hill start assist
phase.
If you need to leave the vehicle
while the engine is running, apply
the parking brake manually then
ensure that the parking brake
warning lamp is on (not fl ashing)
in the instrument panel.
On a descending slope, with the vehicle
stationary and reverse gear engaged,
the vehicle is held for a brief moment
when you release the brake pedal.
Operating fault
If a malfunction of the system occurs,
these warning lamps come on. Contact
a CITROËN dealer or a qualifi ed work-
shop to have the system checked.

Maintenance
In the event of a malfunction with the
system, the "ECO OFF"
switch warning
lamp fl ashes, then comes on continu-
ously.
have it checked by a CITROËN dealer
or a qualifi ed workshop.
In the event of a fault in STOP mode,
the vehicle may stall. It is then neces-
sary to switch off the ignition and start
the engine again using the key.
Operating fault
Before working under the bon-
net, deactivate the Stop & Start
system to avoid any risk of injury
resulting from automatic operation
of START mode.
This system requires a specifi c battery
with a special specifi cation and technol-
ogy (reference numbers available from
a CITROËN dealer or a qualifi ed work-
shop).
Fitting a battery not listed by
CITROËN introduces the risk of mal-
function of the system.
The Stop & Start system makes
use of advanced technology. All
work on this type of battery must
be done only by a CITROËN
dealer or a qualifi ed workshop.
