Operation in automatic mode
Automatic changing between the
4 or 6 gears.
Selector on
D.
The gearbox always selects the
gear best adapted to the following
parameters:
- style of driving,
- route proile,
- vehicle load.
The gearbox then operates in
automatic mode, without requiring
any action on your part.
Notes:
When braking, the gearbox
shifts down automatically to offer
effective engine braking.
The gearbox also enhances
your safety by not changing up
when you lift your foot from the
accelerator abruptly.
To obtain maximum acceleration
without touching the lever, press
rapidly down on the accelerator
pedal (kick down). The gearbox
will automatically change down or
maintain the selected gear up to
maximum engine speed. A U T O M A T I C G E A R B O X
Warning:
- Never select N function if the
vehicle is moving.
- Never select P or R if the vehicle
is not stationary.
- Do not change from one function to another to try to improve
braking on a slippery surface.
If, while the vehicle is moving,
function N is engaged inadvertently,
let the engine idle before engaging
a function that is appropriate. Snow programme
In addition to the automatic
programme, you have this special
programme which facilitates
starting and traction when road
grip conditions are poor.

Operation
When either the ESP or ASR system is brought into operation, the ESP/
ASR warning lamp lashes.
Deactivation
In exceptional conditions (vehicle stuck in snow, soft ground, e tc.) it may
prove useful to deactivate the ESP/ASR system to allow the wheels to spin
and thus regain traction.
- press control A.
- The ESP/ASR warning lamp lights up, accompanied by an audible signal
and the message ESP/ASR DEACTIVATED on the multifunction screen.
Then the ESP/ASR systems are no longer active.
The ESP/ASR systems will redeploy:
- automatically if the ignition has been switched off or as soon as the
vehicle reaches approx. 50 km/h (approx. 30 mph),
- manually by a renewed press on the control A.
Operational anomaly
If the system is malfunctioning, ESP/ASR warning lamp lights up al ong
with the SERVICE warning lamp, a beep and the message “ESP/ASR
FAULT” on the multifunction screen.
Consult a CITROËN dealer to have the system checked.
Electronic Stability Programme (ESP) and Traction Control (ASR)
These systems are closely connected to the ABS and additional to i
t. In
the event of a loss of control of the vehicle by the driver, the ESP system
acts automatically on one or more brakes and also on the engine to bring
the vehicle back on trajectory. The ASR system optimises traction and
prevents wheel spin by acting on the brakes of the driving whe els. It also
improves steering stability during acceleration. E L E C T R O N I C S T A B I L I T Y P R O G R A M M E
Safety recommendations
The ESP system offers increased
driving safety but is not in place
to encourage the driver to take
additional risks or to drive at
excessive speeds.
The functioning of this system is
subject to compliance with the
manufacturer’s recommendations
on wheels (tyres and rims), brake
parts and electronic components,
as well as with CITROËN’s
assembly and repair procedures.
After any collision, have this
system checked by a CITROËN
dealer.

These actions do not cancel the cruise speed which
remains displayed on the screen.
Reactivation of cruise control

- By recalling the memorised cruise speed:
After a deactivation, press button 3.
Your vehicle returns automatically to the memorised
cruise speed which is displayed on the instrument
panel screen B.
If the memorised cruise speed is higher than the speed
at which you are currently travelling, the vehicle will
accelerate strongly to compensate.
- By selection of the current speed:
Press briely on button 2 or 4 when you are at your
desired speed.
The information “OFF” will then disappear from the
screen.
To cancel the function
- By moving the control from “CRUISE” position to
position 0.
- By stopping the engine.
The speed previously chosen is no longer
memorised.
In the event of a malfunction , a message is displayed,
accompanied by a sound signal and lighting of the
SERVICE warning lamp.
Consult your CITROËN dealer.
Cruise control must only be used where road conditions permit driving at a constant speed.
Do not use it on congested roads or when weather and ro ad conditions are poor.
The driver must still remain attentive and in complete co ntrol of the vehicle.
You are recommended to keep your feet within range of the pedals.
To exceed the cruise speed temporarily
While cruise control is operating, it is still possible to
go above the cruise speed by actioning the accelerator
pedal (for example to overtake another vehicle). The
speed displayed on the screen lashes. You have
only to release the accelerator pedal to return to the
memorised speed.
Adjusting the cruise speed while cruise control is
in operation
You can adjust the cruise speed,
displayed in zone B,
by pressing:
- Button 4 to increase the speed.
- Button 2 to reduce the speed.
Note: you can use successive presses to modify the
cruise speed in steps of 1 mph and a continuous press
to jump in steps of 5 mph.
Deactivation of cruise control with memorised
speed
- Either with a press on the brake pedal or clutch pedal.
- Or if ESP or ASR are activated.
- Or with a press on button 3.
Note: cruise control is disengaged when the gear lever
is in neutral position.
These actions bring up the dis-
play “OFF” in the instrument
panel screen. C R U I S E C O N T R O L

This driving assistance device allows you to choose a maximum speed.
This has to be over 30 km/h (approx. 20 mph).
Control

control stalk.
Note: The information relating to the speed limiter is displayed in the
instrument panel screen at B.
To select the function
Turn control 1 to position “LIMIT”.
On selection of the function via control 1, the last
speed memorised is displayed.
The information “OFF” then disappears from the
screen.
To adjust the maximum speed
Provided the engine is running, you can adjust the memorised spe
ed by
pressing:
- button 4 to increase the memorised speed,
- button 2 to decrease the memorised speed.
Note: you can use successive presses to modify the cruise speed in steps
of 1 mph and a continuous press to jump in steps of 5 mph.
To activate the speed limiter
If the desired limit speed is displayed, press button 3 to activate this limit.
While the function is active, pressing the accelerator pedal w ill not enable
you to go beyond the programmed speed unless you press the pedal
hard down past the tight spot (see “Temporary exceeding of the maximum
speed”).
Note: The vehicle speed may vary slightly from that memorised. S P E E D L I M I T E R

To deactivate the speed limiter
Press button
3 located on the end of control A.
A mat not approved by CITROËN risks sliding under the a ccelerator pedal, thus preventing you
from pressing past the tight spot.
It will then be impossible to exit from your speed limita tion, unless by resorting to the control
under the steering wheel.
The driver must still remain attentive and in complete co ntrol of the vehicle.
This action causes the information
“OFF” to appear in the instrument panel screen.
The memorised speed remains displayed and is not cancelled.
Temporary exceeding of the maximum speed
You can exceed the memorised maximum speed at any time by pressing th e accelerator pedal hard down past the
tight spot.
During the time the limit speed is being exceeded, the dis played speed lashes.
Simply release the accelerator pedal to return below the limit speed and make the function active again.
Note: if during use of the speed limiter the system is not able to retain the memorised speed (e.g. on a steep
descent), then the speed lashes. If necessary, adjust your driving speed.
The function will re-engage when your speed is again below the desired limit speed.
To cancel the function
- By moving the control from position “LIMIT” to position 0.
- By stopping the engine.
The speed previously chosen is memorised.
In the event of a malfunction , a message is displayed, accompanied by a sound signal and lig hting of the
SERVICE warning lamp. Consult your CITROËN dealer. S P E E D L I M I T E R
