SAFETY RECOMMENDATIONS
The ESP system offers increased driving safety but is not in place to encourage the driver to take addi-tional 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 as-parts and electronic components, components,
sembly and repair procedures.
After any collision, have this system checked by a CITROËN dealer.After any collision, have this system , have t
Electronic stability programme (ESP) and traction control (ASR)
These systems are closely connected to the ABS and additional to it. 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 wheels, as well as on the engine. It also improves steering stability during acceleration.
Operation :
When either the ESP or ASR system is in operation, the ESP/ASR warning lamp fl ashes.
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 on control A, the ESP/ASR warning lamp and the control light up. The ESP/ASR systems are no longer active.
The ESP/ASR systems will activate again :
- Automatically after the ignition has been switched off.
- Automatically above a speed of 50 km/h (30 mph).
- Manually with a new press on control A.
Operational anomaly
If the systems malfunction, the ESP/ASR warning lamp comes on, ac-companied by a sound signal and a message on the multifunction display. Contact a CITROËN dealer to have the system checked.companied by a sound signal and a message on the multifunction by a sound

Stopping the function
- by an action on the control on position "REG" to position 0.
- by the engine stopping.
The cruise speed previously cho-sen is no longer memorised.
If there is a malfunction,a mes-sage will display accompanied by a sound signal and lighting of the SERVICE warning lamp.
Contact 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 pe dals.
To avoid any risk of interfering with the pedals :
- check that the fl oor mat is correctly positioned,
- never use more than one fl oor mat.
Re-engaging cruise control
-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 wll 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 thendisappear from zone A.
Observation : If during the opera-tion of cruise control, the system is unable to keep within the memo-rised speed (for example on a steep descent), then the speed fl ashes. Adapt your speed as necessary.
Disengaging of cruise control while retaining the memorised speed
- 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.
Note : cruise control is not active if the gear lever is in neutral.
These actions cause the informa-tion "OFF" to appear in zone A of the instrument panel.
These manœuvres do not cancel the cruise speed which remains displayed in the instrument panel.

The tools are to be found either in the compartment under the second-row passenger footwells or in the well under the third-row seats (de-pending on equipment).
Switch on your hazard warning lights, ensure that any passengers leave the vehicle and fi nd a safe place to wait away from traffi c (e.g. behind crash barriers or on a grass verge).
Never get underneath the vehicle if it is supported only by the jack ; use a stand.
It is essential not to exceed a speed of 80 km/h (50 mph) on your spare wheel.
Have the original wheel repaired and refi tted as soon as possible.

REMOVING A WHEEL
1. Park the vehicle on level, sta-ble and non-slippery ground. Apply the parking brake.
Switch off the ignition, check that the parking brake is ap-plied (message and warning lamp in the instrument panel) and engage fi rst gear or re-verse gear depending on the slope (P if an automatic gear-box, D or R if a 6-speed elec-tronic gearbox).
2. Use a chock to secure the ve-hicle more safely. Place the chock in front of the wheel that is opposite the wheel affected.
3. Detach the trim using the re-moving tool 4, pulling in the area of the valve.
For vehicles with alloy wheels, insert the trim removing tool 1into the recess in the central trim and lever it off.
For vehicles with alloy wheels that have visible bolts, remove the chromes covers using the tool 2.
Before any operation of this sort, it is advisable to deactivate your pneumatic suspension (see “Pneumatic sus-pension”). When changing a wheel, it is essential to immobil ise the vehicle on ground that is level, stable and non-slippery.
4. Slacken the wheel bolts. For vehicles with alloy wheels, undo the anti-theft bolts using tool 9.
5. Position the jack under the vehicle (see diagrams), at the jacking point A closest to the wheel to be changed.
6. Unwind the jack 5 until its bracket is in contact with the ground. Make sure that the jack is vertical under the jack-ing point used.
7. Continue to extend the jack so as to raise the vehicle.
8. Undo the wheel bolts and re-move the wheel.
