Practical information
AdBlue
and SCR system for BlueHDi Diesel engines
®
To assure respect for the environment and
conformity with the new Euro 6 emissions
standard, without adversely affecting the
performance or fuel consumption of Diesel
engines, PEUGEOT has taken the decision to
equip its vehicles with an effective system that
associates the SCR system (Selective Catalytic
Reduction) with a particle filter (FAP) for the
treatment of exhaust gases.

SCR system

Using a fluid called AdBlue
containing urea, a
®
catalytic converter turns up to 85% of nitrogen
oxides (NOx) into nitrogen and water, which are
harmless to health and the environment.
TheAdBlue
is contained in a specific tank of
®
approximately 17 litres. Its capacity allows a
driving range of around 12,500 miles
(20,000 km). An alert system is triggered
automatically once the reserve level is reached:
you can then drive for a further 1,500 miles
(2,400 km) before the tank is empty.
During each scheduled service of your vehicle
by a PEUGEOT dealer or a qualified workshop,
the AdBlue
tank is refilled in order to allow
®
normal operation of the SCR system.
If the estimated mileage of your vehicle
between two services is greater than
12,500 miles (20,000 km), it will be necessary
to top-up the AdBlue
.
®
Once the AdBlue
tank is empty, a system
®
required by regulations prevents starting
of the engine.
If the SCR system is faulty, the level of
emissions from your vehicle will no longer
meet the Euro 6 standard: your 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
650 miles (1,100 km), a system will be
triggered automatically to prevent engine
starting.
In either case, a range indicator gives you
the distance you can travel before the
vehicle is immobilised.
