Checking levels
take care when working under the
bonnet, as certain areas of the engine
may be extremely hot (risk of burns) and
the cooling fan could start at any time
(even with the ignition off).
Engine oil level
the check is carried out either when
the ignition is switched on using the
oil level indicator in the instrument
panel for vehicles with and electric oil
level gauge, or using the dipstick.
to e
nsure that the reading is correct,
your vehicle must be parked on a level
sur face and the engine having been off
for more than 30 minutes.
It is normal to top up the oil level between
two services (or oil changes). P

recommends that you check the level, and top
up if necessary, every 3 000 miles (5 000 kms). Check all of these levels regularly, in line with the warranty and maintenance record. t

If a level drops significantly, have the corresponding system checked by a P

dealer or a qualified workshop.
Checking using the dipstick

Before topping-up the oil or changing the oil,
check that the oil is the correct grade for your
engine and conforms to the manufacturer's
recommendations.

Engine oil change
Refer to the warranty and maintenance record
for details of the interval for this operation.
In order to maintain the reliability of the engine
and emission control system, the use of

Fluid specification
the coolant must conform to the
manufacturer's recommendations.
Fluid specification
For optimum cleaning and to avoid freezing,

Particle filter (Diesel)
the start of saturation of the
particle filter is indicated by
the temporary illumination of

in the multifunction screen.
As soon as the traffic conditions permit,
regenerate the filter by driving at a
speed of at least 40 mph (60 km/h) until
the warning lamp goes off.
If the warning lamp stays on, this
indicates a low additive level.
On a new vehicle, the first particle
filter regeneration operations may be
accompanied by a "burning" smell,
which is per fectly normal.
Following prolonged operation of the
vehicle at very low speed or at idle,
you may, in exceptional circumstances,
notice the emission of water vapour at

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: you
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.

Range indicators
the engine start prevention system
required by regulations is activated
automatically once the AdBlue
® tank is

When switching on the ignition, an indicator
gives an estimate of the distance that can
be travelled with your vehicle before engine
starting is automatically prevented, once the
vehicle starts using the reserve of AdBlue
® or
after a fault is detected with the SCR system.
In the event of simultaneous system fault and
low AdBlue
® level, the shortest range is the one
displayed. Range greater than 1 500 miles (2 400 km)
When the ignition is switched on, no
information on range is displayed automatically
in the instrument panel.
