Checking levels
Check all of these levels regularly, in line with
the manufacturer's service schedule. Top them
up if necessary, unless other wise indicated.
If a level drops significantly, have the
corresponding system checked by a PEUGEOT
dealer or a qualified workshop.The fluid must comply with the
manufacturer's recommendations and
with the vehicle's engine.
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).
Used products
Avoid prolonged contact of used oil or
fluids with the skin.
Most of these fluids are harmful to health
or indeed very corrosive. Do not discard used oil or fluids into
sewers or onto the ground.
Take used oil to a PEUGEOT dealer or
a qualified workshop and dispose of it in
the containers reser ved for this purpose.
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 equipped with an
electric gauge, or using the dipstick.
To ensure that the reading is correct, your
vehicle must be parked on a level sur face
with the engine stopped for more than
30


minutes.
It is normal to top up the oil level between
two ser vices (or oil changes). PEUGEOT
recommends that you check the level, and top
up if necessary, every 3,000
miles (5,000 km).
Checking using the dipstick
F Take the dipstick by its coloured grip and pull it out completely.
F

W
ipe the end of the dipstick using a clean
non-fluffy cloth.
F

R
efit the dipstick and push fully down, then
pull it out again to make the visual check:
the correct level is between marks A and B .
A = MA X
B = MIN
If you find that the level is above the A mark or
below the B mark, do not star t the engine.
-

I
f the level is above the MAX mark (risk of
damage to the engine), contact a PEUGEOT
dealer or a qualified workshop.
-

I
f the level is below the MIN mark, you must
top up the engine oil.
The location of the dipstick is shown in the
corresponding underbonnet layout view.

F

A
fter checking the level, carefully refit the oil
filler cap and the dipstick in its tube.
After topping up the oil, the check when
switching on the ignition with the oil
level indicator in the instrument panel
is not valid during the 30
minutes after
topping up.
Engine oil change
In order to maintain the reliability of the engine
and emissions control system, never use
additives in the engine oil.
Brake fluid level
The brake fluid level should be close
to the "MA X" mark. If it is not, check
the brake pad wear.
Changing the fluid
Refer to the manufacturer's service schedule
for details of the inter val for this operation.
Fluid specification
This fluid must conform to the manufacturer's
recommendations.
Coolant level
Check the coolant level regularly.
It is normal to top up the fluid
between two services. A low coolant level presents a risk of serious
damage to your engine.
The coolant level should be close to the "MA X"
mark but should never exceed it.
If the level is close to or below the "MIN" mark,
it is essential to top up.
When the engine is hot, the temperature of the
coolant is regulated by the fan.
In addition, as the cooling system is
pressurised, wait at least one hour after
switching off the engine before carrying out any
work.
To avoid the risk of scalding when you need to
top up in an emergency, place a cloth around
the cap and unscrew the cap by two turns to
allow the pressure to drop.
Once the pressure has dropped, remove the
cap and top up to the required level.
The cooling fan may star t after
switching off the engine: take care
with articles and clothing that might
be caught by the fan blades.Fluid specification
This fluid must conform to the manufacturer's
recommendations.
Oil grade
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.
The check and top up must only be done with
the engine cold.
Practical information

.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.

Practical information

232
Air filter
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.
Oil filter
Change the oil filter each time the
engine oil is changed.
Particle filter (Diesel)
The start of saturation of the particle
filter is indicated by the temporary
illumination of this warning lamp
accompanied by a message about
the risk of the filter clogging up.
As soon as the traffic conditions permit,
regenerate the filter by driving at a speed
of at least 37
mph (60 km/h) until the
warning lamp goes off.
If the warning lamp stays on, this indicates
a low Diesel additive level.
For more information on Checking levels ,
refer to the corresponding section. 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 the
exhaust on acceleration. This does not
affect the behaviour of the vehicle or the
environment.
Manual gearbox
The gearbox does not require any
maintenance (no oil change).
Automatic gearbox
The gearbox does not require any
maintenance (no oil change).
Brake pads
Brake wear depends on the style
of driving, particularly in the case
of vehicles used in town, over short
distances. It may be necessary to
have the condition of the brakes
checked, even between vehicle
services.
Unless there is a leak in the circuit, a drop in
the brake fluid level indicates that the brake
pads are worn.
Brake disc wear
For information on checking brake
disc wear, contact a PEUGEOT
dealer or a qualified workshop.
Electric parking brake
This system does not require any
routine servicing. However, in the
event of a problem, have the system
checked by a PEUGEOT dealer or a
qualified workshop.

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

235
Recommendations on storage
AdBlue® freezes at about -11°C and
deteriorates above 25°C. Containers should
be stored in a cool area and protected from
direct sunlight.
Under these conditions, the fluid can be kept
for at least a year.
If the fluid has frozen, it can be used once it
has completely thawed out.
Never store AdBlue
® containers in your
vehicle.
Precautions for use
In certain conditions (high 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 container.
Procedure
Before starting the top up procedure, ensure
that the vehicle is parked on a flat and level
sur face.
In winter, check that the temperature of the
vehicle is above -11°C. If not, in freezing
weather, the AdBlue
® cannot be poured into the
tank. Park your vehicle somewhere warmer for
a few hours before topping up.
In the event of an AdBlue
® breakdown,
confirmed by the message "Add AdBlue:
Starting impossible", you must top up with
at least 5

litres.
Never pour AdBlue
® into the Diesel fuel
tank. 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.
If the fluid has crystallised, clean it off
using a sponge and hot water.
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

K
eyless Entr y and
Star ting system into the passenger
compartment .
Switch on the ignition, then wait for

ith

K

eyless Entry and Starting, press the
" START/STOP " button to switch off the
engine.
AdBlue
® is a urea-based solution. This fluid
is non-flammable, colourless and odourless
(stored in a cool place).
In the event of contact with the skin, wash the
affected area with soap and running water. In
the event of contact with the eyes, immediately
rinse 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.
