fuel pump PEUGEOT 308 2018 Owners Manual

217
Operation
When a petrol filler nozzle is introduced into
your Diesel tank, it comes into contact with the
flap. The system remains closed and prevents
filling.
Do not persist but introduce a Diesel type
filler nozzle.It remains possible to use a fuel can to fill
the tank.
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 and pour slowly.
Located in the filler neck, the misfuel prevention
device appears when the filler cap is removed.
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 PEUGEOT dealer network,
whether your vehicle is suitable for the
fuel pumps in the country in which you
intend to travel.

Top up to the required level when
necessary.
Capacity of the tank:
-

5

.3

litres for the "very cold climate"
versions.
-

2

.2

litres for other versions.
Fluid specification
The screenwash fluid must be topped up with a
ready for use mix.
In winter (temperatures below zero), a fluid with
antifreeze must be used that is appropriate for
the prevailing conditions, in order to preser ve
the elements of the system (pump, tank, ducts,
e t c .) .
Filling with pure water is prohibited under all
circumstances (risk of freezing, limestone
deposits, etc.).
Diesel fuel additive level
(Diesel with particle filter)
The additive reser voir low level is
indicated by fixed illumination of this
warning lamp, accompanied by an
audible signal and a message that
the particle filter additive level is
too low.
To p p i n g u p
The reser voir must be topped up without delay
by a PEUGEOT dealer or a qualified workshop.
AdBlue level
An alert is triggered once the reser ve level is
reached.
To avoid the vehicle being immobilised as per
regulations, you must top up with AdBlue.
For more information on AdBlue and the SCR
system, and in particular topping it up, refer to
the corresponding section.
Screenwash fluid level
Checks
Unless otherwise indicated, check these
components in accordance with the
manufacturer's service schedule and
depending on your engine.
Other wise, have them checked by a PEUGEOT
dealer or a qualified workshop.
12 V battery
The battery does not require any maintenance.
However, check regularly that the terminals
are correctly tightened (versions without quick
release terminals) and that the connections
are clean.
For more information on the precautions
to take before starting work on the 12 V
battery , refer to the corresponding
section.
Versions equipped with Stop & Start are
fitted with a 12
V lead-acid battery of
specific technology and specification.
Its replacement should be carried out
only by a PEUGEOT dealer or a qualified
workshop.
Filter, passenger compartment
Depending on the environment
(e.g. dusty atmosphere) and the
use of the vehicle (e.g. city driving),
replace it twice as often, if
necessary .
A clogged passenger compartment
filter may have an adverse effect on
the per formance of the air conditioning
system and generate undesirable odours.

AdBlue® (BlueHDi
engines)
To respect the environment and ensure
compliance with the Euro 6 standard, without
adversely affecting the per formance or fuel
consumption of Diesel engines, PEUGEOT
has taken the decision to equip its vehicles
with a system that associates SCR (Selective
Catalytic Reduction) with a Diesel particle filter
(DPF) for the treatment of exhaust gases.
SCR system
Using a liquid called AdBlue® that contains
urea, a catalytic converter turns up to 85% of
the nitrogen oxides (NOx) into nitrogen and
water, which are harmless to health and the
environment.
The AdBlue
® is contained in
a special tank holding about
17


litres.
An alert system is triggered automatically once
the reser ve level is reached: you can then drive
for a further 1,500

miles (2,400 km) before the
tank is empty. Once the AdBlue
® tank is empty, a
s
ystem required by regulations prevents
starting of the engine.
If the SCR

system is defective, 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 travelling the distance of
685

m

iles (1,100

k

m), a system preventing
the engine starting will be triggered
automatically.
In either case, a range indicator gives you
the distance you can travel before the
vehicle is immobilised.
For more information on the Warning
and indicator lamps and the associated
alerts, refer to the corresponding section.
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 very cold conditions.
Supply of AdBlue®
It is recommended that the AdBlue® is
topped up as soon as the first alert is
issued indicating that the reser ve level
has been reached.
In order to ensure that the SCR system
operates correctly:
-

U

se only AdBlue
® fluid that meets the
ISO 22241 standard.
-

N

ever transfer AdBlue
® to another
container: it would lose its purity.
-

N

ever dilute AdBlue
® with water.
You can obtain AdBlue
® from a PEUGEOT
dealer or a qualified workshop.
You can also visit a ser vice station
equipped with AdBlue
® pumps specially
designed for private vehicles.
Never top up from an AdBlue
® dispenser
reserved for heavy goods vehicles.
Practical information

F Obtain an AdBlue® container. After first
checking the use-by date, read the
instructions on the label carefully before
pouring the contents of the container or
bottle into your vehicle's AdBlue tank.
Or F

I
nsert the AdBlue
® pump nozzle and refill
the tank until the nozzle stops automatically.
Important:
-

T

o avoid over flowing the
AdBlue
® tank, it is recommended:
•
T
o top up between 10 and 13 litres
using AdBlue
® containers.
Or
•

T

o not keep on trying after the
nozzle's first automatic stop if you
are refuelling at a filling station.
-
I

f your vehicle's AdBlue
® tank
is completely empty – which is
confirmed by the alert messages
and the impossibility of starting
the engine – you must add at least
5


litres.
After refilling
F Refit the blue cap to the tank filler and turn it 1/6 of a turn clockwise, to its stop.
F

C

® containers in
the household waste.
