12 V battery
The presence of this label indicates the use of a 12 V lead-acid battery with special technology and specification, for which the involvement of a CITROËN dealer or qualified workshop is required when replacing or disconnecting the battery. Failure to observe this recommendation may cause premature wear of the battery.
The battery is located under the bonnet. To gain access to it:  open the bonnet using the interior release lever, then the exterior safety catch,  remove the plastic cover on the (+)
terminal,  if necessary, unclip the fusebox to remove the battery.
Access to the battery
 Raise the locking tab D fully to release the cable terminal clamp E .
Reconnecting the (+) cable
 Position the open clamp E of the cable on the positive post (+) of the battery.  Press vertically on the clamp E to position it correctly on the battery.  Lock the clamp by spreading the positioning lug and then lowering the tab D .
Do not apply excessive force on the tab as locking will not be possible if the clamp is not positioned correctly; start the procedure again.
Before doing any work on your vehicle, switch off the ignition ( Ready lamp off) to avoid any risk of injury resulting from automatic operation of the engine.
Your vehicle is fitted with a conventional 12 V battery, located under the bonnet, in addition to the high voltage battery used by the hybrid system. In certain conditions, if the 12 V battery is too discharged to activate the hybrid system, recharging from another conventional 12 V battery is possible. Do not carry out this recharge if the Readylamp is on.
Procedure for starting the engine using another battery or charging a discharged battery.
Disconnecting the (+) cable

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 .

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.
