Recommendations for ventilation and air conditioning
the air conditioning system does not contain chlorine and does not present any danger to the ozone layer. In order for these systems to be fully effective, follow the operation and maintenance guidelines below:
F 
I
 f the interior temperature remains very high after the vehicle has been parked in the sun for a considerable time, first ventilate the 
passenger compartment for a few minutes.
 P
 lace the air flow control at a sufficient level to provide an adequate renewal of air in the passenger compartment.
F   t

 btain an even air distribution, take care not to obstruct the exterior air intake grilles located at the base of the windscreen, the nozzles, 
the vents and the air outlets, as well as the air extractor located in the boot.
F  
I
 n normal conditions, use the intake of exterior air as prolonged use of the air recirculation may cause misting of the windows and side 
windows.
F  
D
 o not cover the sunshine sensor, located on the dashboard; this is used for regulation of the automatic air conditioning system.
F  
O
 perate the air conditioning system for 5 to 10 minutes, once or twice a month to keep it in good working order.
F   e
n
 sure that the passenger compartment filter is in good condition and have the filter elements replaced regularly (refer to the "Checks" 
section).
 W
 e recommend the use of a combined passenger compartment filter.  t
h
 anks to its second special active filter, it contributes to the 
purification of the air breathed by the occupants and the cleanliness of the passenger compartment (reduction of allergic symptoms, bad 
odours and greasy deposits).
F   t
h
 e air conditioning uses power from the engine while operating.  t
h
 is results in an increase in the vehicle's fuel consumption.
 W
hen towing at or near maximum capacity or on steep slopes in high ambient temperatures, switching off the air conditioning saves engine 
power and so improves towing capacity.
 C
 ondensation created by the air conditioning results in a discharge of water under the vehicle when stationary, which is per fectly normal.
F   t
o e
 nsure correct operation of the air conditioning system, you are also advised to have it checked regularly.

Low fuel level
When the low fuel level in the tank is 
reached, this warning lamp comes on 
in the instrument panel, accompanied 
by an audible warning and a message 
in the instrument panel screen.
Fuel supply cut-off
Your vehicle is equipped with a safety device 
which cuts off the fuel supply in the event of 
a
 
collision. It is still possible to use a fuel can to fill 
the tank but this must be done slowly.
In order to ensure a good flow of fuel, 
do not place the nozzle of the fuel can 
in direct contact with the flap of the 
misfuel prevention device.
Diesel misfuel prevention
Travelling abroad
As Diesel fuel pump nozzles may be different 
in other countries, the presence of the misfuel 
prevention device may make refuelling 
impossible.
Not all Diesel vehicles are fitted with misfuel 
protection, so before travelling abroad, we 
recommend that you check with the P
e
uge
Ot
  
dealer network, whether your vehicle is suitable 
for the fuel pumps in the country in which you 
want to travel.
When it first comes on, around 7 litres of fuel 
remain in the tank.
You must refuel as soon as possible to avoid 
running out.
Mechanical device which prevents filling the tank of a Diesel vehicle with petrol. It avoids the risk of 
engine damage that can result from filling with the wrong fuel.
Located in the filler neck, the misfuel prevention device appears when the filler cap is removed.
When a petrol filler nozzle is introduced into the 
fuel filler neck of your Diesel vehicle, it comes 
into contact with the flap. 
th
e system remains 
closed and prevents filling.
Do not persist, but introduce a Diesel filler 
nozzle.

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.

Topping-up the AdBlue® additive
Filling the AdBlue® tank is an operation 
included in every routine service on your 
vehicle by a P
e
uge
Ot
  dealer or a qualified 
workshop.
Nevertheless, given the capacity of the tank, 
it may be necessary to top-up the additive 
between services, more particularly if an alert 
(warning lamps and a message) signals the 
requirement.
You can go to a P
e
uge
Ot
  dealer or a qualified 
workshop.
If you envisage topping-up yourself, please 
read the following warnings carefully.Precautions in use
Keep AdBlue® out of the reach of 
children, in its original bottle.
Never transfer AdBlue
® to another 
container: it would lose its purity.
us
 e only AdBlue
® additive that meets the 
ISO 
22241 standard.th
e AdBlue® additive is an urea-based 
solution. 
th
is liquid is non-flammable, 
colourless and odourless (kept in a cool area).
In the event of contact with the skin, wash 
the affected area with soap and water. In the 
event of contact with the eyes, wash (irrigate) 
the eyes with large amounts of water or with 
an eye wash solution for at least 15 minutes. 
If a burning sensation or irritation persists, get 
medical attention.
If swallowed, immediately wash out the mouth 
with clean water and then drink plenty of water.
In certain conditions (high ambient 
temperature, for example), the risk of release 
of ammonia cannot be excluded: do not inhale 
the product. Ammonia vapour has an irritant 
effect on mucous membranes (eyes, nose and 
throat). Never dilute the additive with water.
Never pour the additive into the Diesel 
fuel tank.
th
e supply in a non-drip bottle simplifies 
topping-up. You can obtain 1.89 litre (half a 
u
S 
g
allon) bottles from a P
e
 uge
Ot 
 dealer or a 
qualified workshop.
Never top-up from an AdBlue
® 
dispenser reserved for heavy goods 
vehicles.
Freezing of the AdBlue
® additive
th
e AdBlue
® additive freezes at 
temperatures below around -11°C.
th
e SCR system includes a heater 
for the AdBlue
® tank, allowing you to 
continue driving in very cold conditions.
