Emergency braking
In the event of failure of the electronic
stability control system, signalled by
the illumination of this warning lamp,
braking stability is then not guaranteed.
In the event of a failure of the main service
brake or in an exceptional situation (e.g. driver
taken ill, under instruction, etc) a continuous
pull on the control lever A will stop the vehicle.
The electronic stability control provides stability
during emergency braking.
If the emergency braking malfunctions,
the message "Parking brake faulty" will be
displayed.
In this event, stability must be assured by the
driver by repeating alternate "pull-release"
actions on the control lever A
.

without the accelerator being pressed.
Never leave children unsupervised in
the vehicle when the engine is running.
When carrying out maintenance with
the engine running, apply the parking
brake and select position P .
Automatic operation
F Select position d for automatic changing
of the six gears.
The gearbox then operates in auto-adaptive
mode, without any intervention on the part
of the driver. It continuously selects the most
suitable gear according to the style of driving,
the profile of the road and the load in the
vehicle.
For maximum acceleration without touching
the selector, press the accelerator pedal down
fully (kick down). The gearbox changes down
automatically or maintains the gear selected
until the maximum engine speed is reached.
On braking, the gearbox changes down
automatically to provide effective engine
braking.
If you release the accelerator sharply, the
gearbox will not change to a higher gear for
safety reasons.
Never select position
n while the
vehicle is moving.
Never select positions P or R unless
the vehicle is completely stationary.
If position
n
is engaged inadvertently
while driving, allow the engine to
return to idle then engage position
d
to
accelerate.
If you do not press the brake pedal when
trying to move the gear selector out
of position P , this warning lamp or this
symbol appears in the instrument panel accompanied
by a message, flashing of the P symbol, the display of
a message and an audible signal.
F Check that the display in the instrument panel agrees with the position engaged.

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
audible signal and a message appears.
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.
driving

System which keeps your vehicle immobilised
temporarily (approximately 2 seconds) when
starting on a gradient, the time it takes to
move your foot from the brake pedal to the
accelerator pedal.
This function is only active when:
-
t
he vehicle is completely stationary, with
your foot on the brake pedal,
-

w
hen certain conditions of gradient
are
met,
-

w
ith the driver’s door closed.
The hill start assist function cannot be
deactivated.
Hill start assist
On an ascending slope, with the vehicle
stationar y, the vehicle is held for a brief
moment when you release the brake pedal:
-

i
f you are in first gear or neutral with a
manual gearbox,
-

i
f 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
flashing) 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 fault occurs with the system, these warning
lamps come on. Contact a CITROËN dealer
or a qualified workshop to have the system
checked.

203
Gear efficiency indicator*
On vehicle fitted with a manual
gearbox, the arrow may be
accompanied by the gear
recommended.
With an automatic gearbox, the system
is only active in manual mode.
* Depending on engine.
On BlueHDi Diesel 150 versions with manual
gearbox, the system may suggest changing into
neutral so that the engine can go into standby
(STOP mode with Stop & Start), in certain
driving conditions. In this case,
n
is displayed
in the instrument panel. System which reduces fuel consumption by recommending the most appropriate gear.
Operation
Depending on the driving situation and your
vehicle's equipment, the system may advise
you to skip one (or more) gear(s). You can
follow this instruction without engaging the
intermediate gears.
The gear engagement recommendations must
not be considered compulsory. In fact, the
configuration of the road, the amount of traffic
and safety remain determining factors when
choosing the best gear. Therefore, the driver
remains responsible for deciding whether or not
to follow the advice given by the system.
This function cannot be deactivated. Example:
-

Y
ou are in third gear.
-

Y
ou press the accelerator pedal.
-

T
he system may suggest that you engage
a higher gear.
The information appears in the instrument
panel in the form of an arrow.
The system adapts its gear change
recommendation according to the
driving conditions (slope, load,
...) and
the demands of the driver (power,
acceleration, braking,
...).
The system never suggests:
-

e
ngaging first gear,
-
enga

ging reverse gear.
