Automatic operation

 Move the selector to po-
sition D . The gearbox is then operating in

auto-adaptive mode, without requir-
ing any intervention on your part.
For certain manoeuvres (for exam-
ple overtaking), you can obtain max-
imum 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 en-
gage a higher gear. Temporary manual operation
when in automatic mode
The gearbox constantly selects the
gear that is best suited to the follow-
ing parameters:
- driving style,
- road profi le,
- vehicle load. An action on the levers
" + " or " - "
allows you to exercise temporary
control over the changing of gears.
The request to change gear will be
taken into account. You will still be in
automatic mode. The warning lamp

D remains lit up in the instrument
panel.
This function enables you to antici-
pate certain situations such as the
approach of a bend or the need to
overtake another vehicle.

gear changing.
 Move the selector to po-
sition M .
 Pull the lever " + " to change up a
gear.

 Pull the lever " - " to change down

- If the vehicle stops or reduces speed (for example when ap-
proaching a stop sign), the gear-
box changes down automatically
to fi rst gear.
- In sequential mode, it is not nec- essary to release the accelerator
during gear changes.
- A request to change gear is ac- cepted only if the engine speed
permits it. - For safety reasons, depending
on the engine speed, a change
up or down may be performed
automatically.
- It is possible at any time to move from position D (driving in auto-
matic mode) to position M (driving
in sequential mode) or vice versa.
The fl ashing of the warn-
ing lamp for the position
requested signals that this
position is not yet obtained.
If the warning lamp is on fi xed, the
position is confi rmed.
Display of a dash in the rev counter
indicates a malfunction. Consult a
CITROËN dealer.
Lighting of the service warning
lamp accompanied by a message
and a sound signal indicates a
functioning anomaly. In this case:
- a marked snatching may be felt when selecting R for reverse
gear,
- the gearbox is locked on a gear,
- do not exceed a speed of 100 km/h (approx. 60 mph).

CRUISE CONTROL
System which automatically main-
tains the vehicle speed programmed
by the driver, without any action on
the accelerator pedal.
The cruise control is switched on
manually: the vehicle speed must be
at least 25 mph (approx. 40 km/h)
and you must engage:
- fourth gear on a manual gearbox,
- second gear, in sequential mode, on an electronic gearbox or au-
tomatic gearbox,
- position A on an electronic gear-
box or D on an automatic gearbox.
Steering wheel controls
The cruise control switches are lo-
cated on the left-hand side of the
steering wheel. The programmed information is
grouped together in zone
A of the
instrument panel display.
Displays on the instrument
panel
Activation You can then release the accelera-
tor pedal. The vehicle will automati-
cally keep to the speed chosen.
The speed of your vehicle may vary
slightly in relation to that memo-
rised.
You can adjust the memorised speed
on the instrument panel display by
pressing on:

 button 4 to increase the speed,

 button 2 to decrease the speed.
Successive presses modify the
cruise speed in steps of 1 mph and a
sustained press in steps of 3 mph.
Deactivation

 Either by pressing on the brake
pedal or on the clutch pedal.

 Or by pressing button 3 .

 Or if either the ESP or the ASR
system is active.
The cruise control is not active if the
gear lever is in neutral.
On selection of the
function via control
1,
no cruise speed has
yet been memorised.
Programming
Rotate the control
1 to the "REG"
position.
Once the desired speed has been
reached using the accelerator, press
button 2 or button 4 . The cruise
speed is then memorised. It is dis-
played in zone A of the instrument
panel. These actions cause
the information
"OFF"
to appear on the instru-
ment panel display.
These actions do
not cancel the cruise
speed which remains
displayed in the instru-
ment panel.
The cruise control cannot, in any circum-
stances, take the place of the observ-
ance of speed limits or of the vigilance
and responsibility of the driver.

Brake pads Brake wear depends on
the style of driving, par-
ticularly in the case of ve-
hicles used in town, over
short distances. It may be
necessary to have the condition of
the brakes checked, even between
vehicle services.
Unless there is a leak in the circuit, a
drop in the brake fl uid level indicates
that the brake pads are worn.
Manual gearbox
The gearbox does not re-
quire any maintenance (no
oil change).
6-speed electronic gearbox
system
The gearbox does not require any
maintenance (no oil change).
Automatic gearbox
The gearbox does not require any
maintenance (no oil change). Brake disc wear
For information relating to
checking the brake disc
wear, contact a CITROËN
dealer.
Parking brake
If a loss of effectiveness of this sys-
tem is noticed, the parking brake
must be checked, even between two
services.
This system must be checked by a
CITROËN dealer. Only use products recom-
mended by CITROËN or
products of equivalent qual-
ity and specifi cations.
In order to optimise the operation
of units as important as the braking
system, CITROËN selects and of-
fers very specifi c products.
To avoid damaging the electrical
units, the use of a high pressure
washer in the engine compartment
is strictly prohibited .
