You can change mode at any
time by moving the gear lever
from A
to M
or the other way
round.
At low high speed, if reverse gear is
requested, the N
indicator fl ashes and
the gearbox goes into neutral automati-
cally. To engage reverse, put the gear
lever in position N
, then position R
.
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, ensure
that the gear lever is in neutral N
and that the parking brake is ap-
plied.
Whatever the circumstances,
you must manually apply the
parking brake when parking,
unless the parking brake is pro-
grammed in automatic mode.
Reverse
To engage reverse gear R
, the vehicle
must be immobilised with your foot on
the brake pedal.
Select position R
.
Operating fault
With the ignition on, the fl ashing of
AUTO
, accompanied by an audible sig-
nal and a message in the screen, indi-
cates a malfunction of the gearbox.
Have it checked by a CITROËN dealer
or a qualifi ed workshop.
Manual mode
Select position M
.
The gears engaged appear in
succession in the instrument
panel screen.
The gear change requests are only act-
ed on 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.
On sharp acceleration, the gearbox will
not change up unless the driver acts on
the gear lever or the steering mounted
paddles.
Temporary control of gear changing
You can temporarily take over control
of gear changing using the "+"
and "-"
steering mounted paddles: if the engine
speed allows, the request to change
gear is acted on.
This function allows you to anticipate
certain situations such as overtaking a
vehicle or the approach to a corner.
After a few moments without any action
on the control paddles, the gearbox re-
sumes automatic control of the gears.
Never select neutral N
while the
vehicle is moving.
Stopping the vehicle
Before switching off the engine, you
can:
- move to position N
to engage neutral,
or
- leave the gear engaged; in this
case, it will not be possible to move
the vehicle.
In both cases, you must apply the
parking brake
to immobilise the vehicle.

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 mov-
ing 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
after 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 accelera-
tor and brake pedals at the
same time,
- if you force the lever from
position 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 gear-
box 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), lo-
cal 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:
- if you are in fi rst gear or neutral with
a manual gearbox,
- if you are in position A
or M
with an
electronic gearbox.
- if 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 as-
sist phase.
If you need to leave the vehi-
cle while the engine is running,
apply the parking brake manu-
ally then ensure that the parking
brake warning lamp is on (not
fl ashing) in the instrument panel.
On a descending slope, with the ve-
hicle stationary and reverse gear en-
gaged, the vehicle is held for a brief
moment when you release the brake
pedal.
Operating fault
If a fault occurs with the system, these
warning lamps come on. Contact a
CITROËN dealer or a qualifi ed work-
shop to have the system checked.
