Service indicator
The display, located in the control
block, informs you when the next
service will be due in accordance
with the "Manufacturer's" servicing
schedule indicated in the servicing
booklet. This information is determined
in relation to the distance travelled
since the previous service. A few seconds after the ignition is
switched on, the oil level is displayed,
then the total distance recorder
resumes normal operation showing the
total and trip distances.
The distance remaining before the next
service is less than 500 miles/1 000 km
Each time the ignition is switched on
and for a few seconds, the spanner
fl ashes and the number of miles/
kilometres remaining is displayed: A few seconds after the ignition is
switched on, the oil level is displayed,
then the total distance recorder
resumes normal operation and the
spanner remains lit. This indicates that
a service should be carried out shortly.

The service is overdue
Each time the ignition is switched on
and for a few seconds, the spanner
fl ashes and the excess distance is
displayed.
With the engine running the
spanner remains lit until the
service has been carried out.

Example: 4 800 miles/km remain
before the next service is due. When
the ignition is switched on and for a
few seconds, the display shows:
Refer to the list of checks in the
servicing booklet which was given
to you on delivery of the vehicle.
Operation
A few moments after the ignition
has been switched on, the spanner
indicating a service operation lights
up; the display for the total distance
recorder tells you (in round fi gures)
the distance remaining before the next
service.
The points at which a service is due
are calculated from the last indicator
zero reset.
The point at which a service is due is
determined by the distance travelled. For further information, consult

Automatic changing of the six gears .
Moving off
- It is essential to press
the brake pedal to exit
position P ,
- select position R or D ,
You can also move off from position N .
- gradually release the
pressure on the brake
pedal; the vehicle moves
off immediately.
- With your foot on the brake, release
the handbrake,
- select position R , D or M ,
- gradually release the pressure on the brake
pedal; the vehicle moves
off immediately. The gearbox always selects the most
suitable gear according to the following
parameters:
- the style of driving,
- the road profi le,
- the vehicle load.
The gearbox is then operating in auto-
adaptive mode, without any action on
your part. For immediate maximum
acceleration without touching the
gear lever, press the accelerator
pedal down as far as it will go to the
end of its travel passing the point of
resistance (kickdown). The gearbox will
automatically change down or maintain
the gear selected until maximum
engine speed is reached.
With the engine running, to move off
from position
P .
Automatic mode
On a descent, the gearbox will
automatically change down in order to
provide effi cient engine braking and
good re-acceleration.
If you take your foot off the accelerator
suddenly, the gearbox will not change
to a higher gear for reasons of safety.
When stationary with the gear lever in
position D (drive), a vibration limiting
device is activated by pressing the
brake pedal.
- Select position D .

- press the lever to the+ sign to change to a
higher gear, from 1 to 6,
- conversely, press the lever to the - sign to change to a
lower gear. You can change from position
D
(automatic mode) to position M
(manual mode) at any time.
Stopping the vehicle, starting
the engine
Reverse gear
- Select position
R , with the
vehicle stationary and the
engine at idle.
If the battery is fl at and the lever is
in position P , it will be impossible
to change to another position. - Select position
P to

immobilise the vehicle or
to start the engine , with
the handbrake on or off.
- You can also select position N to park or to

start the engine , with the
handbrake on.
If position N is engaged
inadvertently while driving, allow
the engine to return to idle before
engaging position D to accelerate.
Manual mode
Manual changing of the gears by
pressing.
- Select lever position M , In manual mode, it is only possible to
change from one gear to another if
the vehicle speed and engine speed
permit. If they do not, the vehicle will

Good practice
Never select position N when the
vehicle is moving.
Never select positions P or R unless
the vehicle is stationary.
Never change between positions to
optimise braking on a slippery surface.
There is a risk of damage to the
gearbox:
- if you press the accelerator and brake pedals at the same time,
- if you force the lever from position P to another position in the
event of a battery failure.
When the engine is at idle, brakes
not applied, if position R , D or M is
selected the vehicle moves even
without the accelerator being pressed.
For this reason, do not leave children
unsupervised inside the vehicle,
with the engine running .
Operating abnormality
Any operating abnormality is indicated
by an audible signal, accompanied by
the message "Automatic gear fault"
on the display and fl ashing of the Snow
snowfl ake on the instrument panel.
In this situation the gearbox operates
in downgrade mode (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),
keeping within the limit of local speed
restrictions.
Contact a CITROËN dealer as soon as
possible.
You can return to the automatic
programme at any time.
- Press button  again to switch off
the programme you are in.
Snow programme
In addition to the automatic
programme, there is a special
Snow programme.
This improves starting
and drive when traction is
poor. The snowfl ake appears on the
instrument panel display.
- Press button  once the
vehicle has been started
and position D selected.
The gearbox adapts to driving
on slippery roads.
