Practical information
7For more information on the precautions
to take before any 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 with
special technology and specifications.
Its replacement should be carried out only by
a PEUGEOT dealer or a qualified workshop.
Passenger compartment
filter
Depending on the environment and the
use of the vehicle (e.g. dusty atmosphere,
city driving), change it twice as often, if
necessary .
A clogged passenger compartment filter
can adversely affect air conditioning
system performance and generate
undesirable odours.
Air filter
Depending on the environment and the
use of the vehicle (e.g. dusty atmosphere,
city driving), change 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 clogging of the
particle filter is indicated by the
temporary lighting of this warning lamp,
accompanied by an alert message.
As soon as traffic conditions allow, regenerate
the filter by driving at a speed of at least 37
mph
(60

km/h), with an engine speed above 2,500
rpm, for about 15 minutes (until the warning lamp
goes out).
If it is not possible to reach 37
mph (60 km/h),
leave the engine running at idle for about 15
minutes, then drive with an engine speed
above
2,500 rpm for 15 minutes.
Do not switch off the engine until the filter
is fully regenerated; repeated intervals
can degrade the engine oil prematurely.
Regenerating the filter while the vehicle is
stationary is not recommended.
Following prolonged operation of the
vehicle at very low speed or at idle, you
may, in exceptional circumstances, notice
water vapour coming from the exhaust while
accelerating. These emissions have no
impact on the vehicle’s behaviour and the
environment.
New vehicle
During the first few particle filter
regeneration operations, you may notice a
"burning" smell. This is perfectly normal.
Manual gearbox
The gearbox does not require any maintenance (no oil change).
Automatic gearbox
The gearbox does not require any maintenance (no oil change).
Drive selector
The drive selector does not require any maintenance.
Manual parking brake
If you notice excessive brake lever travel
or decreased effectiveness, the parking
brake must be adjusted, even between two
services.
This system must be checked by 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, do not hesitate to 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.

Practical information
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.
After washing the vehicle, moisture, or in wintry conditions, ice can form on the
brake discs and pads: braking efficiency may
be reduced. Gently dab the brakes to dry and
defrost them.
Brake disc/drum wear
For any information on checking brake
disc/drum wear, contact a PEUGEOT
dealer or a qualified workshop.
Wheels and tyres
The inflation pressure of all tyres, including the spare wheel, must be
checked on "cold” tyres.
The pressures indicated 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 over 31 mph (50
km/h), add
0.3 bar (30 kPa) to the values indicated on the
label.
Under-inflation increases energy
consumption. Non-compliant tyre
pressures cause tyres to wear prematurely
and have an adverse effect on the vehicle's
road holding - risk of accident!
Driving with worn or damaged tyres reduces the
braking and road holding performance of the
vehicle. Regularly check the condition of the
tyres (tread and sidewalls) and rims as well as
the presence of the valve caps.
When the wear indicators no longer appear set
back from the tread, the depth of the grooves is
less than 1.6 mm; replace the tyres as soon as
possible.
Using different size wheels and tyres from those
specified can affect the lifetime of tyres, wheel
rotation, ground clearance, 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.
Always mark the direction of rotation on the tyres
that will be stored when fitting winter or summer
tyres. Store them in a cool, dry place and away
from direct exposure to the sun's rays.
Winter or 4-seasons tyres can be
identified by this symbol on their
sidewalls.
Shock absorbers
It is not easy for drivers to detect when
shock absorbers are worn. Nevertheless, the shock absorbers have a major impact on
road holding and braking performance.
For your safety and driving comfort, it is
important to have them regularly checked by a
PEUGEOT dealer or a qualified workshop.
Timing and accessory kits
The timing and accessory kits are used
from the time the engine is started until it
is switched off. It is normal for them to wear over
time.
A
faulty timing or accessory kit can damage
the engine, rendering it unusable. Observe the
recommended replacement frequency, stated in
distance travelled or time elapsed, whichever is
reached first.
AdBlue® (BlueHDi)
To respect the environment and ensure 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 combines 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

Practical information
be excluded: do not inhale the fluid. Ammonia
vapours have an irritant effect on mucous
membranes (eyes, nose and throat).
Store 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 surface.
In wintry conditions, ensure that the temperature
of the vehicle is above -11°C. Otherwise the
AdBlue
® may be frozen and so cannot be poured
into the tank. Park the vehicle in a warmer area
for a few hours to allow the top-up to be carried
out.
Never pour the AdBlue® into the Diesel
fuel tank.
If any AdBlue® is splashed, or if there are
any spillages on the bodywork, 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, it is essential to wait around 5
minutes before switching on the ignition,
without opening the driver’s door,
unlocking the vehicle, inserting the key
into the ignition switch, or bringing the
key for the "Keyless Entry and Start"
system into the passenger compartment.
Switch on the ignition, then wait for 10
seconds before starting the engine.
►

Switch off the ignition and remove the key
from the switch to switch off the engine.
or
►


With Keyless Entry and Start, press the
"

START/STOP" button to switch off the engine.
Accessing the AdBlue® tank

► To access the AdBlue® tank, open the front
left-hand door.
►

T

urn the blue cap a 6
th of a turn
anti-clockwise.
►

Release the cap upwards.
►


With a container of

AdBlue
®: after checking
the expiry date, read the instructions on the
label carefully before pouring the contents of the
container into the vehicle's AdBlue tank.
►

With an


AdBlue® pump: insert the nozzle and
fill the tank until the nozzle automatically cuts
out.
► After filling, perform the same sequence of
operations in reverse order .
In order not to overfill the AdBlue® tank:
–
Add between 10 and 13 litres using
AdBlue® containers.
–
Stop after the nozzle’ s first automatic cut-
out, if you are refilling at a service station.
The system only registers AdBlue
® top-ups of
5

litres or more.
If the AdBlue® tank is completely empty
– which is confirmed by the message
“Top up

AdBlue: Starting impossible ” – it is
essential to add at least 5 litres.
Free-wheeling
In certain situations, it is necessary to put the
vehicle into free-wheeling mode (e.g. towing, on
a rolling road, automatic car wash (Wash mode),
rail or sea transport).
The procedure varies according to the type of
gearbox and parking brake.
Never leave the vehicle unattended with
the vehicle into free-wheeling mode.

H. Speed limit sticker.
The vehicle's electrical system allows the
connection of the compressor for long
enough to inflate a tyre after a puncture
repair.
Only use the two 12 V sockets, located at the
front, to connect your compressor.
Repair and sealing
procedure
► Park the vehicle without obstructing any
traffic and apply the parking brake.
►

Follow the safety instructions (hazard
warning lamps, warning triangle, wearing high
visibility vest, etc.) according to the legislation in
force in the country where you are driving.
► Switch off the ignition.► Turn the selector A to the "Repair"
position.
►

Check that switch
B is in position " O".
Avoid removing any foreign bodies which
have penetrated the tyre.


► Uncoil the white pipe G fully.
► Unscrew the cap from the white pipe.
►

Connect the white pipe to the valve of the
tyre to be repaired.
►


Connect the compressor's electrical plug to
the vehicle's 12 V socket.
► Affix the speed li mit sticker.
The speed limit sticker must be secured
to the interior of the vehicle in the driver's
field of vision, to remind you that a wheel is in
temporary use.
► Start the vehicle and leave the engine
running.
Do not start the compressor before
connecting the white pipe to the tyre
valve: the sealant product would be expelled
through the pipe.
►

Switch on the compressor by moving switch
B

to position I until the tyre pressure reaches
2.0 bars. The sealant product is injected under
pressure into the tyre; do not disconnect the
pipe from the valve during this operation (risk of
blowback).
If after approximately seven minutes this
pressure is not reached, this indicates
that the tyre is not repairable; contact a
PEUGEOT dealer or a qualified workshop for
assistance.
►

Remove the kit and screw the cap back on
the white pipe.

Take care to avoid contaminating
the vehicle with traces of fluid. Keep the kit to
hand.
Take care, the sealant product is harmful if swallowed and causes irritation to the
eyes.
Keep this product out of the reach of children.
The use-by date of the fluid is marked on the
bottle.
After use, do not discard the bottle in
standard waste, take it to a PEUGEOT dealer
or an authorised waste disposal site.

206
In the event of a breakdown
Do not forget to obtain a new bottle of
sealant, available from a PEUGEOT dealer or
a qualified workshop.


► Drive immediately for approximately three
miles (five kilometres), at reduced speed
(between 12 and 37
mph (20 and 60 km/h)), to
plug the puncture.
►

Stop to check the repair and measure the
tyre pressure using the kit.
Inflating, adjusting and
checking tyre pressures


► Turn selector A to the "Inflation"
position.
►

Uncoil the white pipe G

fully.
►

Connect the white pipe to the valve on the
repaired tyre.
►


Reconnect the compressor's electric plug to
the vehicle's 12

V socket.
►

Start the vehicle and leave the engine
running.
Go to a PEUGEOT dealer or a qualified
workshop as soon as possible.
You must tell the technician that the kit has
been used. After inspection, the technician
will advise you on whether the tyre can be
repaired or if it must be replaced.
►

Adjust the tyre pressure using the
compressor (to inflate: set switch

B to position
"I"; to deflate: set switch B to position "O" and
press button C), according to the vehicle's tyre
pressure label located by the driver's door.
A subsequent loss of pressure indicates that
the puncture has not been fully sealed; contact
a PEUGEOT dealer or a qualified workshop to
have your vehicle repaired.
►

Remove the kit and stow it.
► Drive at reduced speed (50 mph
(80 km/h) max.), limiting the distance
travelled to approximately 125 miles
(200
km).
The compressor can also be used, without injecting sealant, to check and
adjust the tyre pressures.
If after approximately 7 minutes the
required pressure is not reached, this
indicates that the tyre is irreparably damaged;
contact a PEUGEOT
dealer or a qualified
workshop for assistance.
Do not drive more than 125 miles (200
km) with a repaired tyre; see a
PEUGEOT dealer or a qualified workshop to
have the tyre changed.
