 Press the brake pedal.

 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.

 Gradually release the brake ped-
al 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 po-
sition (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 en-
gaging 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
following conditions:
- driving style,
- road profi le,
- vehicle load.
The gearbox is then operating in

auto-adaptive mode, without re-
quiring any action on your part.
For certain manoeuvres (for exam-
ple 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
change up.

 To exit position P , move the se-
lector 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.

LANE DEPARTURE WARNING SYSTEM
System which detects the involun-
tary crossing of longitudinal traffi c
lane markings on the ground (solid
or broken line).
Sensors, fi tted below the front
bumper, trigger a warning if the vehi-
cle drifts over a lane marking (speed
higher than 50 mph (80 km/h)).
This system is particularly useful on
motorways and main roads. Activation

 Press button A , the indicator
lamp comes on.
Deactivation

 Press button A again, the indica-
tor lamp switches off.
The status of the system remains
in the memory when the ignition is
switched off.
Detection
You are warned by the vibration of
the driver's seat cushion:
- on the right-hand side, if the marking on the ground has been
crossed on the right,
- on the left-hand side, if the mark- ing on the ground has been
crossed on the left.
No warning is transmitted while the
direction indicator is active and for
approximately 20 seconds after the
direction indicator is switched off.
A warning may be transmitted if a
direction marking (e.g. arrow) or
non-standard marking (e.g. graffi ti)
is crossed. Operating fault
In the event of a malfunction, the
service warning lamp comes on,
accompanied by an audible signal
and a message on the multifunction
screen.
Consult a CITROËN dealer.
The lane departure warning sys-
tem cannot, in any circumstances,
replace the need for vigilance and
responsibility on the part of the
driver. The detection may be impeded:
- if the sensors are dirty (mud,
snow...),
- if the markings on the ground are worn,
- if there is little contrast between the markings on the ground and
the road surface.

CHECKING LEVELS
Check all of these levels regularly
and top them up if necessary, unless
otherwise indicated.
If a level drops signifi cantly, have the
corresponding system checked by a
CITROËN dealer.
Oil level
Oil change
Refer to the Maintenance and
Warranty Guide for details of the in-
terval for this operation. Oil specifi cation
The oil must correspond to your engine
and conform to the manufacturer's
recommendations.
Brake fluid level
Fluid change
Refer to the Maintenance and
Warranty Guide for details of the in-
terval for this operation.
This fl uid must be changed regu-
larly. Fluid which has been used for
too long may cause a loss of braking
effi ciency.
Fluid specifi cation
The brake fl uid must conform to the
manufacturer's recommendations and
fulfi l the DOT4 standards.
Coolant level
Draining the system
The coolant does not have to be
changed.
Fluid specifi cation
The coolant must conform to the
manufacturer's recommendations.
The reading will only be
correct if the vehicle is on
level ground and the engine
has been off for more than
15 minutes.
The check is carried out either when
the ignition is switched on using the
oil level indicator on the instrument
panel, or using the dipstick.
Between two oil changes, the con-
sumption should not exceed 0.5 litre
per 600 miles (approx. 1 000 km).
Check this level also between each
scheduled service and before long
journeys. The brake fl uid level should
be close to the "MAX" mark.
If it is not, check the brake
pad wear.
The coolant level should be
close to the "MAX" mark but
should never exceed it.
When the engine is warm, the tem-
perature of the coolant is regulated
by the fan. This can operate with the
ignition off.

On vehicles which are fi tted with
a particle emission fi lter, the fan
may operate after the vehicle has
been switched off, even if the en-
gine is cold.
In addition, as the cooling system is
pressurised, wait at least one hour
after switching off the engine before
carrying out any work.
To avoid any risk of scalding, unscrew
the cap by two turns to allow the pres-
sure to drop. When the pressure has
dropped, remove the cap and top up
the level.
In order to maintain the re-
liability of the engine and
emission control system,
the use of additives in the engine
oil is prohibited.

still use functions such as the audio
and telematics system, windscreen
wipers, dipped headlamps, courtesy
lights, etc. for a maximum combined
duration of thirty minutes. Switching to economy mode
Once the thirty minutes are over, a
message appears on the multi-func-
tion screen indicating that the vehicle
has switched to economy mode
and the active functions are put on
