When the engine is hot, the temperature of this
fluid 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.
Fluid specification
This fluid must conform to the manufacturer's
recommendations.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.
Screenwash fluid level
Top up to the required level when
necessary.
Fluid specification
For optimum cleaning and to avoid freezing,
this fluid must not be topped up or replaced
with plain water. In wintry conditions, it is recommended
that you use an ethyl alcohol or methanol
based fluid.
Diesel fuel additive level
(Diesel with particle filter)
A low additive level is indicated by
illumination of this warning lamp,
accompanied by an audible warning
and a message in the instrument
panel screen.
To p p i n g u p
This additive must be topped up without delay
by a PEUGEOT dealer or a qualified workshop.
Checks
Unless otherwise indicated, check these
components in accordance with the
manufacturer's service schedule and according
to 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.
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 .
Practical information

187
Passenger compartment 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.
A clogged passenger compartment
filter may have an adverse effect on
the per formance of the air conditioning
system and generate undesirable odours.
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 signalled by the temporary
illumination of this warning lamp
accompanied by a message warning
of 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).
Parking brake
If excessive travel or a loss of
effectiveness of this system is
noticed, the parking brake must
be checked, even between two
services.
This system must be checked by a PEUGEOT
dealer or a qualified workshop.
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/drum wear
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.
For more information on the Electric
parking brake , refer to the corresponding
section.
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
j o u r n ey. 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.
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.
Fitting different tyres on the front and rear axles
can cause the ESC to mistime. 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.
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 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.
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.
Practical information

189
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 system
r
equired 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. 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 passenger vehicles (for those
versions with access to the AdBlue
® tank
via the fuel filler flap).
Never top up from an AdBlue
® dispenser
reserved for heavy goods vehicles.
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.
If the additive has frozen, it can be used once it
has completely thawed out.
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).
