Limit the causes of excess
consumption

Spread loads throughout the vehicle; place
the heaviest items in the bottom of the boot,
as close as possible to the rear seats.
Limit the loads carried in the vehicle and
reduce wind resistance (roof bars, roof rack,
bicycle carrier, trailer...). Use a roof box in
preference.
Remove roof bars and roof racks after use.

At the end of winter, remove snow tyres and
refi t your summer tyres.



Observe the recommendations on
maintenance

Check the tyre pressures regularly, when
cold, referring to the label in the door
aperture, driver's side.
Carry out this check in particular:


- before a long journey,

- at each change of season,

- after a long period out of use.
Don't forget the spare wheel and the tyres on
any trailer or caravan.

Have your vehicle serviced regularly (engine
oil, oil fi lter, air fi lter...) and observe the
schedule of operations recommended by the
manufacturer.


When refuelling, do not continue after the 3 rd
cut-off of the nozzle to avoid any overfl ow.

At the wheel of your new vehicle, it is only
after the fi rst 1 800 miles (3 000 kilometres)
that you will see the fuel consumption settle
down to a consistent average.

relation to the distance travelled since the
previous service.
Low engine oil pressure

Oil deterioration (1.3 HDi 75 hp engine only) The warning lamp comes on
continuously, accompanied by a
message in the instrument panel screen,
when the system detects that the oil
pressure is too low.
The warning lamp flashes,
accompanied by a message in the
instrument panel screen, when the system
detects deterioration of the engine oil. The
flashing of this warning lamp should not be
considered as a fault wit the vehicle, but
rather as an indication to the driver that the
normal use of the vehicle now requires that

If the oil is not changed, when a
second level of deterioration is
reached, the emissions warning
lamp comes on in the instrument panel and
the engine speed is restricted to 3 000 rpm.
If the oil is still not changed, when a third
level of deterioration is reached, the engine
speed is restricted to 1 500 rpm, so as to
avoid any damage. To avoid damaging the engine, it is
recommended that the oil be changed
on flashing of the engine oil warning lamp.

Access



ELECTRONIC IMMOBILISER

All of the keys contain an electronic
immobiliser device.
This device locks the engine supply system.
It is activated automatically when the key is
removed from the ignition.
After the ignition is switched on, a dialogue
is established between the key and the
electronic immobiliser system.
This warning lamp is switched off
after the ignition is switched on
and the key has been recognised,
the engine can be started.
If the key is not recognised, the engine
cannot be started. Use another key and
have the faulty key checked by a CITROËN
dealer.

Good practice

Do not make any modifications to the
electronic immobiliser system.
Operating the remote control, even when it
is in your pocket, may result in involuntary
unlocking of the doors.
The simultaneous use of other high
frequency equipment (mobile telephones,
domestic alarms…), may interfere with the
operation of the remote control temporarily.

When purchasing a second-hand vehicle:


- ensure that you are given the confidential
card,

- have the keys memorised by a CITROËN
dealer to ensure that the keys in your
possession are the only ones which can
start the vehicle.





CONFIDENTIAL CARD

This is given to you on delivery of your
vehicle with the duplicate keys.
It contains the identification code necessary
for any work carried out by a CITROËN
dealer on the electronic immobiliser system.
This code is hidden by a film, which should
be removed only if necessary.
Keep your card in a safe place, never inside
the vehicle.
When undertaking a long trip or journey,
however, it is advisable to take it with you
along with your personal papers.
Driving with the doors locked may
make access to the passenger
compartment by the emergency services
more difficult in an emergency.
As a safety precaution (with children on
board), remove the key from the ignition when
leaving the vehicle, even for a short time.

HILL START ASSIST


An integral part of the ESP system, it
facilitates starting on a gradient by keeping
your vehicle immobilised temporarily
(approximately 2 seconds), 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,

- the engine is running,

- the gradient is steeper than 5 %,
Operation

On a slope, with engine running and the
vehicle stationary, the vehicle is held
for a brief moment when you release the
brake pedal:


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

- provided you are in position A
or M
with
an electronic gearbox,



On a descending slope, with the vehicle
stationary, the engine running and reverse
gear engaged, the vehicle is held for a brief
moment when you release the brake pedal.



After 2 seconds, if the vehicle has not
moved off, the system is deactivated
automatically by gradually reducing the
brake pressure. During this phase, the
characteristic sound of brakes being
released will be heard, indicating the
imminent movement of the vehicle.
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.

Operating fault
If a fault occurs with the system,
these warning lamps come on in
the instrument panel. Contact a
CITROËN dealer or a qualified
workshop to have the system
checked.
In STOP mode of Stop & Start, hill start
assist is inactive.

Maintenance

In the event of a fault with
the system, the Stop & Start
system is deactivated and the
service warning lamp comes on,
accompanied by a message in the
instrument panel screen.
Have it checked by a CITROËN dealer or a
qualified workshop.
In the event of an operating fault with STOP
mode, it is possible to restart the engine by
depressing the clutch pedal fully and putting
the gear lever into neutral. Before working under the bonnet, you
must switch off the ignition with the
key to avoid any risk of injury resulting from
automatic operation of START mode.
This system requires a specific battery
with a special specification and technology
(reference numbers available from a
CITROËN dealer or a qualified workshop).
Fitting a battery not listed by
CITROËN introduces the risk of malfunction
of the system.
The Stop & Start system makes use
of advanced technology. Specialist
knowledge is needed for any work on the
system, which can only be assured by
CITROËN dealers.


Reactivation

Press the "S - OFF"
switch again.
The system is active again; this is confirmed
by the switch warning lamp going off and a
message in the instrument panel screen.
