in the red zone. When it first comes on there remains 
approximately 7 litres of fuel in the 
tank.
At this point, you begin to use the fuel 
reserve. Refuel as soon as possible to avoid running out of 
fuel.
th

is switched on, until a sufficient addition of fuel is 
made.
Never continue to drive until you run out of fuel, as 
this could damage the emission control and injection

Your vehicle is fitted with a catalytic converter, 
a device which helps to reduce the level of 
harmful emissions in the exhaust gases.
For petrol engines, you must use unleaded 
fuel only.
th

nozzles only.

AdBlue® additive and SCR system
for BlueHDi Diesel engines
to assure respect for the environment and 
conformity with the new 
eu ro 6 emissions 
standard, without adversely affecting the 
per formance or fuel consumption of Diesel 
engines, P
e
uge
Ot
  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.
Presentation of the SCR system
using an additive called AdBlue® 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.
th
 e AdBlue
® 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 P
e
uge
Ot
  dealer or a qualified workshop, 
the AdBlue
® 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 P
e
uge
Ot
  dealer 
or a qualified workshop to have the necessary 
top-up carried out. Once the AdBlue
® tank is empty, a 
s
ystem required by regulations prevents 
starting of the engine.
If the SCR is faulty, the level of 
emissions from your vehicle will no 
longer meet the 
e
u
 ro 6 standard: your 
vehicle becomes polluting.
In the event of a confirmed fault 
with the SCR system, you must go 
to a P
e
uge
Ot
 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.
