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 
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 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. The AdBlue
® is held in a special tank with 
a capacity of about 17 litres: this provides 
a driving range of about 12 500 miles 
(20
 
000
 
km). An alert is triggered automatically 
to warn you when the reserve level is 
reached: you can then drive about 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 
s
ystem 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.
Freezing of the AdBlue
®
AdBlue® freezes at temperatures below 
around -11°C.
The SCR system includes a heater 
for the AdBlue
® tank, allowing you 
to continue driving in all weather 
conditions.
