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.
Presentation of the SCR system
Using a fluid 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. 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), 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
® 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 PEUGEOT 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 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.

When switching on the ignition, this warning
l amp comes on, accompanied by an audible
signal and the display of a message (e.g.: "Top
up emissions additive: Starting prevented in
900 miles") indicating the remaining range
expressed in miles or kilometres.
When driving, the message is displayed every
200 miles (300 km) until the fluid has been
topped-up.
Go to a PEUGEOT dealer or a qualified
workshop to have the AdBlue
® topped-up.
You can also top-up the tank yourself.
For more information on topping-up the
AdBlue
®, refer to the corresponding section.
Remaining range between 350 and 1500 miles (600 and 2 400 km)Remaining range between 0 and 350 miles (0 and 600 km)Breakdown related to a lack of AdBlue®
When switching on the ignition, this warning
lamp flashes, accompanied by an audible
signal and the display of a message (e.g. "Top
up emissions additive: Starting prevented in
350 miles") indicating the remaining range
expressed in miles or kilometres.
When driving, the message is displayed every
30 seconds until the fluid has been topped-up.
Go to a PEUGEOT dealer or a qualified
workshop to have the AdBlue
® topped-up.
You can also top-up the tank yourself.
Other wise you will not be able to restart your
engine. To be able to start the engine,
we recommend that you call on a
PEUGEOT dealer or a qualified
workshop for the top-up required.
If you carry out the top-up yourself, it
is essential to add at least 3.8 litres of
AdBlue
® to the tank.
When switching on the ignition, this warning
lamp flashes, accompanied by an audible
signal and the display of the message "Top up
emissions additive: Starting prevented".
The AdBlue
® tank is empty: the system required
by regulations prevents engine starting.

the AdBlue
®, refer to the corresponding

In the event of the detection
of a fault
In the event of a fault with the SCR emissions control system
During an authorised driving phase (between
650 miles and 0 miles) (1 100 km and 0 km)
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 during the next journey,
after self-diagnosis of the SCR system.
These warning lamps comes on, accompanied
by an audible signal and the display of the
message "Emissions fault".
The alert is triggered when driving when the
fault is detected for the first time, then when
switching on the ignition for subsequent
journeys, while the fault persists.
If a fault with the SCR system is confirmed
(after 30 miles (50 km) covered with the
permanent display of the message signalling
a fault), these warning lamps come on,
accompanied by an audible signal and the
display of a message (e.g.: "Emissions fault:
Starting prevented in 150 miles") indicating
the remaining range expressed in miles or
kilometres.
While driving, the message is displayed every
30 seconds while the fault with the SCR system
persists.
The alert is repeated when switching on the
ignition.
You should go to a PEUGEOT dealer or a
qualified workshop as soon as possible.
Other wise, you will not be able to restart your
engine.

Starting preventedYou have exceeded the authorised
driving limit: the starting prevention
system inhibits engine starting. Freezing of the AdBlue®
Every time the ignition is switched on, these
warning lamps come on, accompanied by an
audible signal and the display of the message
"Emissions fault: Starting prevented".
To be able to start the engine, you must call on
a PEUGEOT dealer or a qualified workshop. AdBlue
® freezes at temperatures below
around -11°C.
The SCR system includes a heater
for the AdBlue
® tank, allowing you to
continue driving in very cold conditions.

Topping-up the AdBlue®
Filling the AdBlue® tank is an operation
included in every routine service on your
vehicle by a PEUGEOT dealer or a qualified
workshop.
Nevertheless, given the capacity of the tank, it
may be necessary to top-up the fluid between
services, more particularly if an alert (warning
lamps and a message) signals the requirement.
You can go to a PEUGEOT dealer or a qualified
workshop.
If you envisage topping-up yourself, please
read the following warnings carefully.Precautions in use
AdBlue® is a urea-based solution. This 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 fluid.
Ammonia vapour has an irritant effect on
mucous membranes (eyes, nose and throat).
Keep AdBlue® out of the reach of
children, in its original bottle.
Never transfer AdBlue
® to another
container: it would lose its purity. Never top-up from an AdBlue
®
dispenser reserved for heavy goods
vehicles. Never dilute AdBlue
® with water.
Never pour AdBlue® into the Diesel fuel
tank.
The supply in a non-drip bottle simplifies
topping-up. You can obtain 1.89 litre (half a US
gallon) bottles from a PEUGEOT
dealer or a
qualified workshop. Use only AdBlue
® fluid that meets the
ISO
22241 standard.

When towing
Distribution of loads
F Distribute the load in the trailer so that the heaviest items are as close as possible to
the axle and the nose weight approaches
the maximum permitted without
exceeding


it.
Air density decreases with altitude, thus
reducing engine performance. Above
1
000 metres, the maximum towed load must
be reduced by 10
% for every 1 000 metres of
altitude.
Side wind
F Take into account the increased sensitivity to side wind.For more information on weights (and
the towed loads which apply to your
vehicle) refer to the corresponding
section.
Cooling
Towing a trailer on a slope increases the
temperature of the coolant.
As the fan is electrically controlled, its cooling
capacity is not dependent on the engine speed.
F

T
o lower the engine speed, reduce your
speed.
The maximum towed load on a long incline
depends on the gradient and the ambient
temperature.
In all cases, keep a check on the coolant
temperature.
F

I
f the warning lamp and the
STOP warning lamp come on,
stop the vehicle and switch off
the engine as soon as possible.
Braking
Towing a trailer increases the braking distance.
To avoid overheating of the brakes, the use of
engine braking is recommended.
Ty r e s
F Check the tyre pressures of the towing vehicle and of the trailer, observing the
recommended pressures.
Lighting
F Check the electrical lighting and signalling on the trailer and the headlamp beam
height of your vehicle.
For more information on adjusting the
headlamp beam height, refer to the
corresponding section.
The rear parking sensors will be
deactivated automatically if a genuine
PEUGEOT towbar is used.
