Get Practical information -> AdBlue? (BlueHDi engines) Guide for Peugeot 308 4 Door Second Genration (2014-2020)

Practical information

The pressures given on the tyre pressure label

are valid for "cold" tyres. If you have driven for

more than 10 minutes or more than 6 miles

(10 kilometres) at more than 31 mph (50 km/h),

0.3 bar (30 kPa) should be added to the values

given on the label.

Under-inflation increases fuel consumption.

Non-compliant tyre pressure causes premature

wear on tyres and has an adverse effect on the

vehicle's road holding – Risk of an accident!

Driving with worn or damaged tyres reduces

braking efficiency and control of the vehicle's

steering. Regular inspections of the condition

of tyres (tread and sides) and rims are

recommended as well as making sure that

valves are fitted.

Brake disc/drum wear

Only use products recommended by

PEUGEOT or products of equivalent

quality and specification.

In order to optimise the operation of

components as important as those in the

braking system, PEUGEOT selects and

offers very specific products.

After washing the vehicle, dampness, or

in wintry conditions, ice can form on the

brake discs and pads: braking efficiency

may be reduced. Make light brake

applications to dry and defrost the brakes.

For information on checking

brake disc/drum wear, contact a

PEUGEOT dealer or a qualified

workshop.

Electric parking brake

This system does not require any

specific check. However, in the

event of a problem, have the system

checked by a PEUGEOT dealer or a

qualified workshop.

AdBlue^®(BlueHDi

engines)

Using different size wheels and tyres from

those specified can affect the lifetime of tyres,

wheel rotation, ground clearance and the

speedometer reading and have an adverse

effect on road holding.

To respect the environment and ensure

For more information on the Electric

parking brake, refer to the corresponding

section.

compliance with the Euro 6 standard, without

adversely affecting the performance or fuel

consumption of its 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.

Fitting different tyres on the front and rear axles

can cause the ESC to mistime.

Wheels and tyres

The pressure must be checked on

all tyres, including the spare wheel,

when the tyres are "cold", at least

once a month and before a long

journey.

SCR system

Using a fluid called AdBlue^®containing urea,

a catalytic converter converts up to 85%

of nitrogen oxides (NOx) into nitrogen and

water, which are harmless to health and the

environment.

188

Practical information

You can also visit a service station

equipped with AdBlue^®pumps specially

designed for passenger vehicles (for those

versions with access to the AdBlue^®tank

via the fuel filler flap).

The AdBlue^®is contained in

a special tank holding about

17 litres.

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.

An alert system is triggered automatically once

the reserve level is reached: you can then drive

for a further 1,500 miles (2,400 km) before the

tank is empty.

Never top up from an AdBlue^®dispenser

reserved for heavy goods vehicles.

Once the AdBlue^®tank is empty, a system

required by regulations prevents starting

of the engine.

If the SCR system 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 travelling the distance

of 685 miles (1,100 km), a system will be

triggered automatically to prevent the

engine from starting.

In either case, a range indicator gives you

the distance you can travel before the

vehicle is immobilised.

Recommendations on

storage

AdBlue^®freezes at about -11°C and

deteriorates above 25°C. It should be stored in

a cool place and protected from direct sunlight.

Under these conditions, the fluid can be kept

for at least a year.

Supply of AdBlue^®

It is recommended that the AdBlue^®is

topped up as soon as the first alert is

issued indicating that the reserve level has

been reached.

If the additive has frozen, it can be used once it

has completely thawed out.

In order to ensure that the SCR system

operates correctly:

7

-

Use only AdBlue^®fluid that meets the

ISO 22241 standard.

Never transfer AdBlue^®to another

container: it would lose its purity.

Never dilute AdBlue^®with water.

Never keep AdBlue^®containers in your

vehicle.

Precautions for use

AdBlue^®is a urea-based solution. This liquid

is non-flammable, colourless and odourless

(when kept in a cool place).

You can obtain AdBlue^®from a PEUGEOT

dealer or a qualified workshop.

189

Practical information

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 you feel

a persistent burning sensation or irritation, get

medical attention.

If swallowed, immediately wash out the mouth

with clean water and then drink plenty of water.

In certain conditions (at high temperature,

for example), the risk of release of ammonia

cannot be excluded: do not inhale the vapour.

Ammonia has an irritant effect on mucous

membranes (eyes, nose and throat).

In the event of an AdBlue^®breakdown,

confirmed by the message "Add AdBlue:

Starting impossible", you must top up with

at least 5 litres.

Important: in the event of a top-up after a

breakdown because of a lack of AdBlue,

you must wait around 5 minutes before

switching on the ignition, without opening

the driver’s door, locking the vehicle,

introducing the key into the ignition

switch, or introducing the key of the

Keyless Entry and Starting system into

the passenger compartment.

Never pour AdBlue^®into the Diesel fuel

tank.

Switch on the ignition, then wait for

10 seconds before starting the engine.

For the specifics associated with the

access configuration for the AdBlue^®tank

(via the boot or via the fuel filler flap), refer

to the descriptions given in detail further

on.

If any AdBlue^®is splashed, or if there are

any spillages on the side of the body, rinse

immediately with cold water or wipe with a

damp cloth.

Keep AdBlue^®in its original container and

out of the reach of children.

If the fluid has crystallised, clean it off

using a sponge and hot water.

Procedure

Before starting the top up procedure, ensure

that the vehicle is parked on a flat and level

surface.

In winter, check that the temperature of the

vehicle is above -11°C. If not, due to freezing,

the AdBlue^®cannot be poured into the tank.

Park your vehicle somewhere warmer for a few

hours before topping up.

Practical information

Access to the AdBlue^®tank

via the boot

With subwoofer

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, as soon as an alert (warning lamps

and a message) indicates it.

You can go to a PEUGEOT dealer or a qualified

workshop.

If you intend to do the topping-up yourself,

read the following procedure carefully.

The supply in a non-drip bottle simplifies

topping up.

F Working inside the boot, lift the carpet and

then, depending on the equipment, lift out

the spare wheel and/or the storage well.

F Without pressing, turn the black cap a

quarter turn anti-clockwise and lift it off.

F Turn the blue cap anti-clockwise.

F Obtain non-drip bottles of AdBlue^®. After

first checking the use-by date, carefully

read the instructions for use on the label

before pouring the contents of the bottle into

your vehicle's AdBlue^®tank.

-

Carefully disengage the wiring harness from

its housing to give a little more free cable

length.

Undo the central nut and remove the

fastener (nut and bolt).

F Switch off the ignition and remove the key.

F After filling, perform the same operations in

reverse order.
