Maintenance indicator zero reset Engine oil level indicator
After each service, the maintenance
indicator must be reset to zero.
Your CITROËN technician resets the
indicator to zero after each service.
However, if you do your own serv-
icing, the procedure for resetting to
zero is as follows:

 switch off the ignition,

 press and hold the trip distance
recorder zero reset button,

 switch on the ignition; the dis-
tance recorder display begins a
countdown,

 when the display indicates "=0" ,
release the button; the spanner
disappears. System which informs the driver
whether the engine oil level is cor-
rect or not.
This information is displayed for a
few seconds when the ignition is
switched on, after the service infor-
mation.
The level read will only be correct if
the vehicle is on level ground and
the engine has been off for more
than 15 minutes.
Oil level correct
Oil level low
This is indicated by the fl ashing of

"OIL" , accompanied by an audible
signal and a message on the multi-
function screen.
If the low oil level is confi rmed by a
check using the dipstick, it is essen-
tial that the level is topped up to pre-
vent damage to the engine. Oil level gauge fault
This is indicated by the fl ashing of

"OIL --" . Contact a CITROËN dealer.
Dipstick
Refer to the "Checks" section to lo-
cate the dipstick and the oil fi ller cap
on your engine. There are 2 marks on
the dipstick:
- A = max; never ex-
ceed this level,
- B = min; top up the
level via the oil fi ller
cap, using the type
of oil suited to your
engine.
Following this operation, if you wish
to disconnect the battery, lock the
vehicle and wait at least fi ve minutes
for the zero reset to be taken into ac-
count.

Air conditioning
To ensure that your system operates
correctly, it is recommended to have
it checked regularly.
Water arising from condensation
in the air conditioning drains away
through a hole provided for this pur-
pose. A pool of water may thus form
under the vehicle when stationary.
To keep the air conditioning com-
pressor well sealed, it is essential to
operate the air conditioning at least
once in every month.
Regardless of the season, the air
conditioning is useful, since it re-
moves humidity and condensation.
To be effective, the air conditioning
should only be used with the win-
dows closed.
If after a lengthy stop in bright sun-
light the interior temperature is ex-
cessive, ventilate the passenger
compartment by opening the win-
dows for a few moments, then close
them again.
The air conditioning operates by
using power from the engine. This
results in a slight increase in fuel
consumption.
Dust filter/Odour filter (active
carbon)
There is a fi lter for excluding odours
and dust.
This fi lter has to be changed in ac-
cordance with the vehicle mainte-
nance schedule (see "Maintenance
Guide").
Air circulation
Maximum comfort is obtained when
there is a good distribution of air in
the passenger compartment, both in
the front and in the rear.
For optimum operating effi ciency,
take care not to obstruct the air out-
lets under the front seats.
Air vents
The face-level air vents have grilles
and thumbwheels to adjust the air
fl ow and direction (up-down, right-left).
The automatic regulation of the air
conditioning, inside the cabin, uses
the sunlight sensor located on the
dashboard behind the instrument
panel.
Be careful not to obstruct it.

TRAJECTORY CONTROL SYSTEMS
Anti-skid regulation (ASR) and
electronic stability programme
(ESP)
The anti-skid regulation optimises
traction to prevent skidding of the
wheels, by acting on the brakes of
the driving wheels and on the en-
gine.
The electronic stability programme
acts on the brake of one or more
wheels and on the engine to keep
the vehicle on the trajectory required
by the driver.
Activation
These systems are activated auto-
matically each time the vehicle is
started.
They come into operation in the event
of a grip or trajectory problem. This is indicated by fl ashing
of this warning lamp on the
instrument panel. Deactivation
In exceptional conditions (starting a
vehicle which is bogged down, stuck
in snow, on soft ground...), it may be
advisable to deactivate the ASR and
ESP systems, so that the wheels
can move freely and regain grip.

 Press the "ESP OFF" button,
located in the centre of the fascia. Reactivation
These systems are reactivated
automatically each time the ignition
is switched back on or from 30 mph
(50 km/h).

 Press the "ESP OFF" button again
to reactivate them manually.
If this warning lamp comes
on in the instrument panel
and the indicator lamp on the
button comes on, this indi-
cates that the ASR and ESP
systems are deactivated. Operating fault
If this warning lamp comes
on, accompanied by an
audible signal and a mes-
sage on the multifunction
screen, this indicates a malfunction
of these systems.
Have the systems checked by a
CITROËN dealer.
The ESP/ASR systems offer excep-
tional safety in normal driving, but
this should not encourage the driver
to take extra risks or drive at high
speed.
The correct functioning of these
systems depends on observation
of the manufacturer's recommen-
dations regarding the wheels (tyres
and rims), the braking components,
the electronic components and the
CITROËN assembly and operation
procedures.
After an impact, have these systems
checked by a CITROËN dealer.

button A to release the handbrake.
When the vehicle is being driven,
if this warning lamp and the STOP
warning lamp come on, accompa-
nied by an audible signal and a mes-
sage on the multi-function screen,
this indicates that the handbrake
is still on or has not been properly
released.
When parking on a slope, direct
your wheels against the pavement,
pull the handbrake on and engage
a gear.

left on multifunction screens A
and C and on the right on the
NaviDrive multifunction screen.
- A background-lit position grille associated with the selector al-
lows you to view the position se-
lected. Moving off

When the ignition is on, light-
ing of the service warning lamp,
accompanied by
an audible
sig-
nal and the message "Gearbox
faulty" indicates a malfunction.
Consult a CITROËN dealer.
For safety:

 Position N can only be disen-
gaged if you are pressing the
brake pedal.

 If the gearbox is in position N
but the selector position is dif-
ferent, reposition the selec-
tor on N in order to be able to
start.
 To start the engine, the selector
has to be in position N .

 Press fi rmly on the brake pedal.

 Operate the starter.

 When the engine is running,
place the selector on R , A or M
as desired.

 Check, in the instrument panel,
the position engaged.

 Release the brake pedal and
accelerate.
If the selector is not in position N ,
and/or if the brake pedal is not
pressed, the corresponding warning
lamp(s) are displayed and a mes-
sage informs you that at least one of
these two conditions is not met.
In this case, the engine will not start,
recommence the above procedure.
Engaging reverse gear
To engage reverse gear, move the
selector to R .

Only attempt to
select
reverse gear
when the vehicle is stationary.
If the vehicle is moving rapidly, if
an inadvertent attempt to engage
reverse gear is made, the warning
lamp N will fl ash and your vehicle
will go automatically into neutral. To
re-engage a gear, you have only to
reposition the selector on A , M or R .

Operation in manual mode

 Move the selector to position M .

Controls
behind
the steering wheel
The paddles behind the steering
wheel give you access to the six for-
ward gears. - In manual mode, it is not neces-
sary to release the accelerator
completely during gear changes.
- A request to change gear is accepted only if the engine
speed permits it.
- For safety reasons, depending on the engine speed, a change
down may be performed auto-
matically.
In situations of high engine speeds
(heavy acceleration), a change
up will not occur unless the driver
operates the paddle.
Acceleration
For optimum acceleration (e.g. to
overtake another vehicle), simply
press the pedal beyond the point of
resistance at the end of its travel, by
pressing down fi rmly.
Vehicle stationary, with the
engine running
In the event of a prolonged stop with
the engine running, the gearbox
changes automatically to neutral N . Stopping the vehicle
Before stopping the engine, you can
choose:

 to leave the vehicle in neutral;
move the selector to position N .

 to leave the vehicle with a gear
engaged ( R , A or M ); place the
selector in the chosen position
prior to stopping the engine. In
this case, the vehicle cannot be
moved.
In all cases, it is essential to apply
the parking brake. Check that the
parking brake warning lamp is lit up
in the instrument panel.
Do not use the accelerator to hold
your vehicle on a gradient. Use
either the brake pedal or the parking
brake.
Before doing anything in the engine
compartment, check that the selec-
tor is in neutral N .
Changing gear

 Pull the " +
" paddle to change up
a gear.

 Pull the " -
" paddle to change
down a gear.
The paddles do not permit you to
select neutral or reverse gear, or to
exit reverse gear.
- If the vehicle stops or reduces speed (for example when
approaching a stop sign), the
gearbox changes down auto-
matically, to fi rst gear if needed.

HILL START ASSIST (WITH THE 6-SPEED ELECTRONIC GEARBOX SYSTEM)
System which holds your vehicle tem-
porarily (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:
- the vehicle is completely stationary, with your foot on the brake pedal,
- in particular conditions on a slope,
- with the driver’s door closed.
The hill start assist function cannot
be deactivated. Operation
Operating fault
If a malfunction of the system
occurs, these warning lamps come
on. Contact a CITROËN dealer to
have the system checked.

On an ascending slope, with the
vehicle stationary, the vehicle is
held for a brief moment when you
release the brake pedal:
- provided you are in A or M on an
electronic gearbox,
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.
do not exit the vehicle while
it is being held in the hill
start assist phase.
If you need to exit the vehicle with
the engine running, manually apply
the parking brake and ensure that
the warning lamp P (red) on the
instrument panel is permanently on.

 Operate the starter.

 When the engine is running,
place the selector on R , D or M
as required.

 Check, in the instrument panel,
the position engaged.

 Release the brake pedal and
accelerate.

 To avoid a difference between
the position of the selector and
the actual position of the gear-
box, only exit from position P
with the ignition on and the brake
pedal pressed.
Park Reverse gear
This position of the selector is used
to prevent the vehicle from moving
when you are stationary.

 To select position P, move the
selector back to the highest
position (towards R ), then push it
forwards and then to the left. Only engage this position when
the vehicle is stationary. To prevent
snatching, do not accelerate too
soon after selection.
Neutral
Never select position N if the vehicle
is moving.
Never select positions P or

R if the vehicle is not sta-
tionary.
If, while the vehicle is moving, po-
sition N is engaged inadvertently,
allow the engine to idle before
engaging position D or M .
Otherwise, when the ignition is on or
the engine is running:

 reposition the selector in position P ,

 put your foot on the brake pedal
and then select the gear you
want. Automatic operation

 Move the selector to position D .
The gearbox constantly selects the
gear that is best suited to the follo-
wing conditions: - driving style,
- road profi le,
- vehicle load.
The gearbox is then operating in

auto-adaptive mode, without requi-
ring any action on your part.
For certain manoeuvres (for example
overtaking), you can obtain maxi-
mum acceleration by pressing the
accelerator pedal down hard, which
then produces an automatic change
down to a lower gear.
When braking, the gearbox may
change down automatically in order
to provide effective engine braking.
If you lift your foot off the accelera-
tor abruptly, the gearbox will not
engage a higher gear.

 To exit position P , move the
selector to the right and then to
the position you want.

 Only engage this position when
the vehicle is completely sta-
tionary. In this position, the front
wheels are locked. Make sure
that the selector is correctly posi-
tioned.

Activation
When the desired maximum speed
is displayed, press button 3 so that
the limitation is activated.
The information "OFF" then disap-
pears from the instrument panel dis-
play.
While the function is active, pres-
sing the accelerator pedal will not
enable the programmed speed to be
exceeded, except if you press the
pedal hard down to beyond the end-
of-travel switch.
The speed of your vehicle may vary
slightly in relation to that memo-
rised.
Deactivation
Press on button 3 .
This action causes the information

"OFF" to appear on the instrument
panel display.
This action does not cancel the
memorised maximum speed which
remains displayed in zone A of the
instrument panel. Override of the programmed
speed
The accelerator pedal is equipped
with an end-of-travel switch. If you
action this switch by pressing the
pedal hard down, you can exceed
the memorised maximum speed at
any time.
During the time the speed is
being exceeded, the displayed
speed fl ashes.
You have only to release the
accelerator pedal to return below
the maximum speed and render the
function active again.
If during the operation of the speed
limiter, the system is unable to keep
within the maximum speed (for exam-
ple on a steep descent or under heavy
acceleration) then the speed fl ashes.
Adapt your speed as necessary.
The function will re-engage when
your speed returns below the desired
maximum speed.
Return to normal driving

 By moving the control 1 from
position "LIM" to position 0 .

 By the engine stopping.
The speed previously chosen is still
memorised.
Operating fault
If there is a speed limiter malfunc-
tion, a message will display accom-
panied by an audible signal and
lighting of the service warning lamp.
Have it checked by a CITROËN
dealer.
On a steep downhill gradient or on
sharp acceleration, the speed limiter
will not be able to prevent the vehi-
cle from exceeding the programmed
speed.
Use of fl oor mats that are not
approved by CITROËN may hinder
access to the accelerator pedal and
thus interfere with the functioning of
the speed limiter.
To avoid any risk of interfering with
the pedals:
- check that the fl oor mat is cor- rectly positioned,
- never use more than one fl oor mat.
