tion, the ESP/ASR warning lamp
lashes.
In the event of a problem
Should there be a malfunction-
ing of the systems, the ESP/ASR

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Then the ESP/ASR systems are no longer active.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.

A
110 IV Air ilter
Follow the recommendations
in the Maintenance Guide.
When working under the bonnet, the cooling fan could
operate if the power unit is hot (even when switched off).
The engine oil level should be checked frequently
between services (as recommended by the manufacturer), as well as before long journeys.
Engine coolant
The coolant level should
be between the
MAX and
MIN marks on the header
tank.
If the engine is hot, wait
15 minutes.
Quality: Consult the Maintenance
Guide.
Never work on the cooling
system if the engine is hot. (See
“Levels”). Engine oil

vehicle parked on horizon-
tal ground, the engine ha-
ving been switched off for at least
15 minutes.
Level: see “Capacities”.
Quality: Consult the Maintenance
Guide. Brake luid
The luid level must be si
-
tuated within the minimum
and maximum marks visi-
ble on the reservoir
Level: See “Levels”.
Quality: Consult the Maintenance
Guide.
If the warning lamp comes on:
stop the vehicle
Power steering oil

y
unscrew the cap to allow the pressure to drop, protecting
yourself with a cloth, for example.
Topping up the cooling system
The coolant level should be between the MIN and MAX marks on t he
header tank.
Top up the level. If you have to add more than 1 litre, h ave the cooling
system checked by a CITROËN dealer.
Fully secure the cap.
Note: The need to top up the coolant frequently is an indicat ion of a
malfunction, which you should have checked at the earliest op portunity.
Note: the cooling fan may operate for some ten minutes after the e ngine
has stopped.

ping up.
Check the level after illing.
It should never exceed the maxi-
mum mark.
Screw on the cap before closing
the bonnet.
Quality:
Consult the Maintenance
Guide.
Brake luid
The synthetic luid not only gives protection against corrosion bu t also
ensures correct functioning of the braking system in all environment al
conditions, therefore you should only use the synthetic product
recommended by the CITROËN network. (this luid must be replaced
every two years).
These important requirements are detailed in your vehicle’s Maint enance
Guide.
Quality: Consult the Maintenance Guide.
Brake luid reservoir
Check and top up at regular
intervals.
The luid level must be situated
within the MAX and MIN marks
visible on the reservoir.

Access to the battery
The battery is located under the loor on the front right
hand side (see “Battery compartment fuses”).
Emergency starting with a slave battery
A vehicle with a discharged battery can be started
with either a slave battery or the battery of another
vehicle.
A Discharged battery
B Slave battery
C Earth point on broken down vehicle.
It is essential to proceed strictly following the sequence
indicated.
Check that the emergency battery is correctly charged
up (12 volts). If you are using the battery on another
vehicle, stop the engine of the assisting vehicle. The
two vehicles must not come into direct contact with
each other.
Connect the cables in the order indicated in the
diagram. Make sure that the clamps are properly
secured (risk of sparks).
Start the engine of the assisting vehicle. Let the engine
run for about a minute at a slightly accelerated speed.
Never apply a lame or create sparks close
to the battery (explosive gas). The battery contains diluted sulphuric acid which is highly corrosive.
If ever you are handling the battery, protect your eyes a nd face.
In the event of any contact with the skin, rinse
immediately with copious amounts of fresh water.
Advice
Replace it with a battery of the
same type (voltage, amp rating).
Do not touch the cable clamps
during the procedure.
Do not lean over the batteries.
Disconnect the cables in the
reverse order to connection,
ensuring that they do not touch
each other. Start the engine of the assisted vehicle.
Note:
For any repair necessitating a disconnection
of the battery, it is essential to wait three minutes
after switching off the ignition and to avoid any action
that could prevent the vehicle’s electrical circuit from
changing to standby mode (such as opening and
closing doors, using the remote control etc.).

QUESTIONSANSWERSSOLUTIONS
The rec eption qualit y of the radio station being listened to gradually deteriorates.
The vehicle is too distant from the transmitter, or no transmitter is present in the geographical area you are passing th rough.
Activate the RDS function to allow the system to chec k whether a more power ful transmitter is to be found in the geographical area.
The environment (hills, high buildings, tunnels, underground car parks, etc.) is blocking reception, even in RDS mode.This phenomenon is normal and does not imply anythi ng wrong with the radio.
The aerial is absent or has been damaged (for example after going through a car wash or in an underground car park).Have the aerial checked by a CITROËN dealer.
When the engine is not running, the radio stops after a few minutes.
When the engine is switched off, the working time fo r the radio depends on the batter y charge. The interruption is nor mal: the radio goes into economy mode, cutting off in order to save the vehicle’s batter y.
You have to star t the engine so as to increase the bat-ter y charge.
T h e m e s s a g e “ t h e a u d i o s y s t e m i s o v e r h e a t i n g ” a p p e a r s o n t h e screen.
In order to protect the audio equipment in excessiv e ambient temperatures, the radio goes into an automatic thermic protection mode which results in a reduction in sound volume or stopping of the CD player.
Switch off the audio system for a few minutes in order to allow the system to cool down.
Why is one not informed in real time of a hold-up on the route even though the option for guidance by “traffi c info” is activated ?
When you star t up, the system takes a few minutes to c apture the traf fi c information via RDS-TMC.Wait for the traf fi c information to be safely received (pictogrammes displayed on the map) and make sure that you use the major ar terial roads to have “inform ed” navigation.
Only the major ar terial roads (motor ways and some d ual car-riageways) are featured in RDS-TMC traf fi c information).
It may happen that a hold-up is not repor ted by the tr af fi c info provider.
Why is a diversion not suggested when I have selected traf fi c info ?
Do not confuse the “traf fi c info” guidance option which can sug-gest a diversion (the “diver t” button appears in the w indow) with the menus “Display of traf fi c messages” or “Reading of traf fi c messages” which af fect only the display without recalculating the itinerar y (no “diver t” button in the window).
To have “informed” navigation with the detour proposi-tion, it is essential to activate the guidance option with “traf fi c info”.
