Do not leave the vehicle while it is being held in the temporary immobilisation hill start assist phase.
To aid starting on a gradient, your vehicle is equipped with a system which keeps it immobilised for a short time (about 2 seconds), the approximate time it takes to move your foot from the brake pedal to the accelerator pedal.

Engine oil level indicator
When you switch the ignition on, the engine oil check is displayed for a few seconds on the instru-ment panel screen.
Note: to ensure that this meas-urement is accurate, check the oil level on horizontal ground after the engine has been switched off for at least 15 minutes. An incorrect engine oil level can seriously dam-age your engine.
“Oil level incorrect” indicates that the oil level is too low.
Check using the manual dipstick. See “Levels”.
If, after topping up, the message re-appears, contact a CITROËN If, after topping up, the message If, after topping up, the message

You are advised to use the auto-matic air conditioning regulation. This automatically regulates the following functions for maximum comfort : air fl ow, passenger com-partment temperature, and air dis-tribution, using different sensors (external temperature, sunlight). This avoids the need to alter any of the settings, with the exception of the temperature displayed.
Take care not to obstruct the sun-light sensor A.
Provided you retain automatic mode (by pressing button “AUTO”) and all the air vents are open, you will maintain an optimum comfort level, also removing humidity and misting, whatever the ambient cli-matic conditions.
The temperature inside the cabin cannot be lower than the tempera-ture outside if the air conditioning is not operating.
To be effective, the air conditioning should only be used with the win-dows closed. If after a lengthy stop in bright sunlight the interior tem-perature is excessive, air the pas-senger compartment by opening the windows for a few moments, then close them again.
Air circulation
For your comfort we advise you to maintain a proper distribution of air within the cabin, both at the front and at the rear.
To obtain an even distribution of air, ensure that you do not obstruct the external air inlet grille located at the base of the windscreen, the air vents, the air outlets on the fl oor underneath the front seats, and the air extractor located behind the fl aps in the boot.
The front and rear air vents are fi t-ted with control knobs which allow you to control and direct the air fl ow. It is recommended to keep all the air vents open.
Dust/pollen fi lter
There is a fi lter for excluding pollen and dust.
This fi lter has to be changed accord-ing to the vehicle maintenance sched-ule. See “Maintenance Guide”.
To ensure the correct operation of the air conditioning system, it is essential to operate the air condi-tioning at least once a month.
The air conditioning operates by using power from the engine. This results in a slight increase in fuel consumption.
In certain extreme operating con-ditions (e.g. carrying a full load up a steep gradient in high tempera-tures), the switching off of the air conditioning allows more power to be transferred to the engine, thereby increasing the towing capacity.
Air inlet
Check that the exterior grille for the air inlet, at the bottom of the wind-screen, is clean and free of dead leaves, snow, etc.
If washing the vehicle with a high pressure jet, avoid targeting the air inlet zone.

Starting the engine with an assisting battery
If the battery is discharged, it is possible to use either a separate emergency battery or a battery on another vehicle.
If you use the battery on another vehicle, stop the engine on the latter. The two vehicles must not come into direct contact with each other.
Check that the assisting battery has suffi cient voltage (12 V).
Lift up the pegs to remove the front left-hand headlamp cover.
Connect the cables according to the order indicated in the dia-ordergram.
A Pole “+” of the broken down vehicle (Under the red cover).B Assisting battery.C Pole “–” of the broken down vehicle (Under the bonnet).
Check that the leads are well secured (risk of sparks).
Start the engine of the assist-ing vehicle. Let the engine run for around 1 minute at a slightly accel-erated idle.
Operate the starter on the vehicle being assisted.
It is essential to follow the indi-cated sequence correctly.
Never approach with a fl ame or create sparks in the vi
cinity of the battery (explosive gas).
The battery contains dilute sulphuric acid which is hig hly corrosive.
When handling batteries, always protect your face and es pecially your eyes.
In the event of any contact with the skin, rinse immediatel y with copious amounts of fresh water.
For any battery replacement, contact a CITROËN dealer.
Do not touch the leads during the operation.
Do not lean over the batteries.
Disconnect the cables in reverse order, making sure they do not touch together.
Advice
Battery location and access
The battery is located in the boot under the left hand wing trim. To access the battery, open the fl ap.
IMPORTANT
In the event of a battery failure, and if the boot is closed, it is then necessary to feed an electrical supply to your vehicle.

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”.
