AdBlue ® additive and SCR system
for Blue HDi Diesel engines
To assure respect for the environment and conformity with the new Euro 6 emissions standard, without adversely affecting the per formance or fuel consumption of Diesel engines, PEUGEOT has taken the decision to equip its vehicles with an effective system that associates SCR (Selective Catalytic Reduction) with a particle emissions filter (PEF) for the treatment of exhaust gases.
Presentation of the SCR system
Using an additive called AdBlue ® containing urea, ® containing urea, ®
a catalytic converter turns up to 85% of nitrous oxides (NOx) into nitrogen and water, which are harmless to health and the environment.
The AdBlue ® additive is held in a special ® additive is held in a special ®
tank located under the boot at the rear of the vehicle. It has a capacity of 17 litres: this provides a driving range of about 12 500 miles (20 000 km), after which an alert is triggered warning you when the reserve remaining is enough for just 1 500 miles (2 400 km).
During each scheduled service of your vehicle by a PEUGEOT dealer or a qualified workshop, the AdBlue ® additive tank is refilled in order to ® additive tank is refilled in order to ®
allow normal operation of the SCR system.
If the estimated mileage between two services is greater than 12 500 miles (20 000 km), we recommend that you go to a dealer to have the necessary top-up carried out.
Once the AdBlue ® tank is empty, a ® tank is empty, a ®
system required by regulations prevents starting of the engine. If the SCR is faulty, the level of emissions from your vehicle will longer meet the Euro 6 standard: you vehicle becomes polluting. In the event of a confirmed fault with the SCR system, you must go to a PEUGEOT dealer or a qualified workshop as soon as possible: after a running distance of 680 miles (1 100 km), a system will be triggered automatically to prevent engine starting.

In the event of a fault with the the SCR emissions control system
A system that prevents engine starting is activated automatically from 650 miles (1 100 km) after confirmation of a fault with the SCR emissions control system. Have the system checked by a PEUGEOT dealer or a qualified workshop as soon as possible.
If it is a temporary fault, the alert disappears once the exhaust gas emissions return to normal.
In the event of the detection of a fault
When switching on the ignition, the UREA, SERVICE and diagnostic warning lamps comes on, accompanied by an audible signal and the display of a message "Emissions fault" to signal a fault with the emissions control system.

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).
Oil level
The check is carried out either when the ignition is switched on using the oil level indicator in the instrument panel, or using the dipstick.
Engine oil change
Refer to the warranty and maintenance record 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.
Oil specifi cation
The oil must be the correct grade for your engine and conform to the manufacturer's recommendations.
Check all of these levels regularly, in line with the warranty and maintenance record. Top them up if necessary, unless other wise indicated. If a level drops significantly, have the corresponding system checked by a PEUGEOT dealer or a qualified workshop.
Dipstick
There are two marks on the dipstick:
A = maximum If the level is above this mark, contact a PEUGEOT dealer or a qualified workshop. B = minimum Top up the level through the oil filler orifice, using the correct grade of oil for your engine. The level must never be below this mark.
It will only be correct if the vehicle is on level ground and the engine has been off for more than 30 minutes. It is normal to top up the oil level between two services (or oil changes). PEUGEOT recommends that you check the level, and top up if necessary, every 3 000 miles (5 000 kms). 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.

Refer to the warranty and maintenance record for details of the interval for this operation.
Fluid specifi cation
The brake fluid must conform to the manufacturer's recommendations.
Coolant level
The coolant level should be close to the "MA X" mark but should never exceed it.
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.
Changing the coolant
The coolant does not have to be replaced at routine services.
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.
When the engine is warm, the temperature of the coolant is regulated by the fan.

wash fluid
In the case of vehicles fitted with headlamp washers, the low fluid level is indicated by an audible signal and a message in the instrument panel screen. Top up the reservoir when you next stop the vehicle.
Avoid prolonged contact of used oil or fluids with the skin.
Most of these fluids are harmful to health or indeed very corrosive.
Do not discard used oil or fluids into sewers or onto the ground. Take used oil to a PEUGEOT dealer or a qualified workshop (France) or to an authorised waste disposal site.

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.
In wintry conditions, the use of an ethyl alcohol or methanol base fluid is recommended.
