Automatic operation
 Move the selector lever
to position 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 accelerator
abruptly, the gearbox will not change up.
Temporary manual operation
when in automatic mode
The gearbox constantly selects the
gear that is best suited to the follow-
ing conditions:
- driving style,
- road profi le,
- vehicle load. At any time, operating the "
+ " or " - "
paddle allows you to exercise tem-
porary control over the gearbox. The
request to change gear will be taken
into account. You will still be in auto-
matic mode. The indicator D remains
on 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.

Manual operation
Position of the selector lever for
manual gear changing.
 Move the selector lever
to position M .
 Pull the " + " paddle to change up
a gear.

 Pull the " - " paddle to change
down a gear.
- 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 (driv-
ing in sequential mode) or vice
versa.
Flashing of the indicator for
the position requested sig-
nals that this position is not
yet obtained.
If the indicator is on fi xed, the posi-
tion 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 an audible signal indicates an
operating fault. In this case:
- a marked snatching may be felt when selecting R for reverse
gear,
- the gearbox is locked in one gear,
-
do not exceed a speed of 60 mph
(approximately 100 km/h).
Consult a CITROËN dealer.

SPEED LIMITER
System which prevents the vehi-
cle from exceeding the speed pro-
grammed by the driver.
Once the limit speed has been
reached, the accelerator pedal no
longer has any effect.
The speed limiter is switched on
manually: a speed of at least 20 mph
(approximately 30 km/h) must be pro-
grammed.
The speed limiter controls are located
on the left-hand side of the steering
wheel. The programmed information is
grouped together in zone
A of the
instrument panel screen.
Steering mounted controls Displays on the instrument
panel
Programming
Rotate the control
1 to the "LIM" po-
sition. With the engine running, you can
adjust the memorised maximum
speed, by means of short or long
presses on:

 button 4 to increase the memo-
rised maximum speed,

 button 2 to decrease the memo-
rised maximum speed.
Successive presses will modify the
maximum speed in steps of 1 mph
(1 km/h) and a sustained press in
steps of 3 mph (5 km/h).
Activation
When the desired maximum speed
is displayed, press button 3 so that
the limitation is activated.
On selection of the
function, the previous
memorised speed and
the information "OFF"
are displayed on the
instrument panel. The information
"OFF"
then disappears from
the instrument panel
screen.
While the function is active, press-
ing the accelerator pedal will not en-
able 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.
The speed limiter cannot, in any circum-
stances, take the place of the obser-
vance of speed limits or of the vigilance
and responsibility of the driver.

Deactivation
Press on button 3 .
This action causes the
information "OFF" to
appear on the instru-
ment panel screen.
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 be-
ing exceeded, the displayed speed
fl ashes.
You have only to release the ac-
celerator pedal to return below the
maximum speed and render the
function active again. Return to normal driving

 By moving the control 1 from po-
sition "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.
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 de-
sired maximum speed.
On a steep downhill gradi-
ent or on sharp accelera-
tion, the speed limiter will
not be able to prevent the vehicle
from exceeding the programmed
speed.
Use of fl oor mats that are not ap-
proved by CITROËN may hinder
access to the accelerator pedal
and thus interfere with the function-
ing 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.

Reactivation

 By recall of the memorised
speed
After a disengagement, press on button 3 . Your vehicle automati-
cally returns to the memorised
cruise speed which is displayed
in zone A .
If the memorised cruise speed is higher than the current speed,
the vehicle will accelerate to
reach the former.

 By selection of the current
speed
Press on button 2 or 4 once the
desired speed has been reached.
The information "OFF" will then
disappear from the instrument
panel display.
Overriding the programmed
speed
During the operation of cruise con-
trol, it is always possible to use the
accelerator to go faster than the
cruise speed (for example to over-
take another vehicle). The speed
displayed in zone A fl ashes.
You have only to release the accel-
erator pedal to return to the cruise
speed. If during the operation of cruise
control, the system is unable to
keep within the memorised speed
(for example on a steep descent),
then the speed fl ashes. Adapt your
speed as necessary.
Return to normal driving Operating fault

If there is a malfunction, a mes-
sage will display accompanied by
an audible signal and lighting of the
service warning lamp.
Have it checked by a CITROËN
dealer.
Cruise control should only
be used when the driving
conditions allow you to drive
at a constant speed.
Do not use it in heavy traffi c, or on
dangerous or slippery roads.
The driver must remain attentive
and in full control of his vehicle.
You are recommended to keep your
feet within range of the pedals.
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.

 By an action on the control 1 from
position "REG" to position 0 .

 By the engine stopping.
The cruise speed previously chosen is no longer memorised.
