On vehicles fitted with HDi engines, the fuel system must be primed if you run out of fuel; refer to the corresponding engine compartment view.
Running out of fuel (Diesel)
If the tank on your vehicle is fitted with a misfuel prevention device, refer to the "Misfuel prevention (Diesel)" section.
 Fill the fuel tank with at least five litres of Diesel.  Open the bonnet.  If necessary, unclip the style cover for access to the priming pump.  Slacken the bleed screw.  Squeeze and release the priming pump repeatedly until fuel appears in the transparent pipe.  Tighten the bleed screw.  Operate the starter until the engine starts (if the engine fails to start at the first attempt, wait around 15 seconds before trying again).  If the engine fails to start after a few attempts, operate the priming pump again, then the starter.  Put the style cover back in position and clip it in place, ensuring that it has clipped c o r r e c t l y.  Close the bonnet.
2 litre HDi engine
If the engine does not start first time, don't keep trying but start the procedure again from the beginning.
Before doing anything under the bonnet, switch off the ignition ( Readylamp off) to avoid any risk of injury resulting from automatic operation of the engine.

Checking levels
Take care when working under the bonnet, as certain areas of the engine may be extremely hot (risk of burns) and the cooling fan could start at any time (even with the ignition off).
Engine oil level
The check is carried out either when the ignition is switched on using the oil level indicator in the instrument panel for vehicles with and electric oil level gauge, or using the dipstick.
To ensure that the reading is correct, your vehicle must be parked on a level sur face and the engine having been off for more than 30 minutes.
Check all of these levels regularly, in line with the maintenance and warranty guide. Top them up if necessary, unless other wise indicated. If a level drops significantly, have the corresponding system checked by a CITROËN dealer or a qualified workshop.
Before doing anything under the bonnet, switch off the ignition ( Readylamp off) to avoid any risk of injury resulting from automatic operation of the engine.
It is normal to top up the oil level between two services (or oil changes). CITROËN recommends that you check the level, and top up if necessary, every 3 000 miles (5 000 kms).
Checking using the dipstick
Refer to the "Diesel engine" section for the location of the dipstick in the engine compartment of your vehicle.
 Take the dipstick by its coloured grip and remove it completely.  Wipe the end of the dipstick using a clean non-fluffy cloth.  Refit the dipstick and push fully down, then pull it out again to make the visual check: the correct level is between the marks Aand B .

A = MA X
B = MIN
If you find that the level is above the A mark or below the B mark, do not star t the engine . - If the level is above the MAX mark (risk of damage to the engine), contact a CITROËN dealer or a qualified workshop. - If the level is below the MIN mark, you must top up the engine oil.
Oil grade
Before topping-up the oil or changing the oil, check that the oil is the correct grade for your engine and conforms to the manufacturer's recommendations.
Topping up the engine oil level
Refer to the "Diesel engine" section for the location of the oil filler cap in the engine compartment of your vehicle.  Unscrew the oil filler cap to reveal the filler aperture.  Add oil in small quantities, avoiding any spills on engine components (risk of fire).  Wait a few minutes before checking the level again using the dipstick.  Add more oil if necessary.  After checking the level, carefully refit the oil filler cap and the dipstick in its tube.
After topping up the oil, the check when switching on the ignition with the oil level indicator in the instrument panel is not valid during the 30 minutes after topping up.
Engine oil change
Refer to the maintenance and warranty guide for details of the interval for this operation. In order to maintain the reliability of the engine and emission control system, the use of additives in the engine oil is prohibited.

Before doing anything under the bonnet, switch off the ignition ( Readylamp off) to avoid any risk of injury resulting from automatic operation of the engine.
The brake fluid level should be close to the "MA X" mark. If it is not, check the brake pad wear.
Brake fluid level
Changing the fl uid
Refer to the maintenance and warranty guide for details of the interval for this operation.
Fluid specifi cation
The brake fluid must conform to the manufacturer's recommendations.
The power steering fluid level should be close to the "MA X" mark. With the engine cold, unscrew the cap to check the level.
Power steering fluid level
Coolant level
The coolant level should be close to the "MA X" mark but should never exceed it.
When the engine is warm, the temperature of the coolant is regulated by the fan.
In addition, as the cooling system is pressurised, wait at least one hour after switching off the engine before carrying out any work. To avoid any risk of scalding, unscrew the cap by two turns to allow the pressure to drop. When the pressure has dropped, remove the cap and top up the level.
Fluid specifi cation
The coolant must conform to the manufacturer's recommendations.
The cooling fan may star t after switching off the engine: take care with ar ticles and clothing that might become caught by the fan blades.

Screenwash / headlamp
wash level
To check the level or top up the fluid on vehicle fitted with headlamp washers, immobilise the
vehicle and switch of the engine.  Before opening the bonnet, ensure that the engine has completely stopped.  Open the screenwash reservoir filler cap.
Topping up
This additive must be topped up by a CITROËN dealer or a qualified workshop without delay.
Diesel additive level
(Diesel engine with particle
emission filter)
A low additive level is indicated by illumination of the service warning lamp, accompanied by an audible warning and a message in the instrument panel screen.
Specifi cation of the fl uid
To ensure optimum cleaning and to avoid freezing, the fluid should never be topped up or replaced by plain water. In wintry conditions, the use of an ethyl alcohol or methanol base fluid is recommended.
 Take and pinch the level gauge to block its breather.  Remove the gauge completely from the reservoir to read the level in the transparent section.  Top up if necessary.  Refit the filler cap to the reservoir and close the bonnet.

Particle emission filter (Diesel)
The start of saturation of the particle filter is indicated by the temporary illumination of this warning lamp accompanied by a message in the multi-function screen. As soon as the traffic conditions permit, regenerate the filter by driving at a speed of at least 40 mph (60 km/h) until the warning lamp goes off. If the warning lamp stays on, this indicates a low additive level.
On a new vehicle, the first particle filter regeneration operations may be accompanied by a "burning" smell, which is per fectly normal. Following prolonged operation of the
vehicle at very low speed or at idle, you may, in exceptional circumstances, notice the emission of water vapour at the exhaust on acceleration. This does not affect the behaviour of the vehicle or the environment.
The 100% electric mode is not available during regeneration of the particle emissions filter.
Air filter and passenger compartment filter
Oil filter
Replace the oil filter each time the
engine oil is changed. Refer to the maintenance and warranty guide for details of the replacement interval for this component.
Refer to the maintenance and warranty guide for details of the replacement intervals for these components.
Depending on the environment (e.g. dusty atmosphere) and the use of the vehicle (e.g. city driving), replace them twice as often if necessary . necessary . necessary A clogged passenger compartment filter may have an adverse effect on the per formance of the air conditioning system and generate undesirable odours.

Electronic gearbox
The gearbox does not require any maintenance (no oil change). Refer to the maintenance and warranty guide for details of the checking interval for this component.
Brake wear depends on the style of driving, particularly in the case of vehicles used in town, over short distances. It may be necessary to have the condition of the brakes checked, even between vehicle services. Unless there is a leak in the circuit, a drop in the brake fluid level indicates that the brake pads are worn.
Brake pads
For information on checking brake disc wear, contact a CITROËN dealer or a qualified workshop.
Brake disc wear
Electric parking brake
This system does not require any routine servicing. However, in the
event of a problem, have the system checked by a CITROËN dealer or a qualified workshop.
Only use products recommended by CITROËN or products of equivalent quality and specification. In order to optimise the operation of units as important as those in the braking system, CITROËN selects and offers very specific products. After washing the vehicle, dampness, or in wintry conditions, ice can form on the brake discs and pads: braking efficiency may be reduced. Make light brake applications to dry and defrost the brakes.
For more information, refer to the "Electric parking brake - Operating faults" section.
