Misfuel prevention (Diesel)
(Depending on the country of sale.)
Mechanical device which prevents filling the
tank of a Diesel vehicle with petrol. It avoids
the risk of engine damage that can result from
filling with the wrong fuel.
Located in the filler neck, the misfuel
prevention device appears when the filler cap
is removed.
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.
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.Towing device
Load distribution
F D
istribute the load in the trailer so that the
heaviest items are as close as possible to
the axle and the nose weight approaches the
maximum permitted without exceeding it. Use towing devices and their genuine
harnesses approved by PEUGEOT. It
is recommended that the installation be
per formed by a PEUGEOT dealer or a
qualified workshop.
If the towing device is not fitted by
a PEUGEOT dealer, it must still be
fitted in accordance with the vehicle
manufacturer's instructions.
Important
: for versions equipped with
the hands-free tailgate, if a towing device
is installed outside of the PEUGEOT
dealer network, it is essential to visit a
PEUGEOT dealer or a qualified workshop
to recalibrate the detection system: risk of
hands-free function malfunction!
Certain driving assistance or manoeuvring
assistance functions are automatically
disabled if an approved towing device is
used.
Air density decreases with altitude, thus
reducing engine performance. The maximum
towed load must be reduced by 10% for every
1,000 metres of altitude.

Practical information

203
It is strongly recommended that before
you leave, you practise fitting the snow
chains on a level and dry sur face.
Avoid driving with snow chains on roads
that have been cleared of snow to avoid
damaging your vehicle's tyres and the
road sur face. If your vehicle is fitted with
alloy wheels, check that no part of the
chain or its fixings is in contact with the
wheel rim.
Fitting roof bars
As a safety measure and to avoid
damaging the roof, it is essential to use
the transverse bars approved for your
vehicle.
You must see a PEUGEOT dealer to
obtain these roof bars and their specific
fixings.
Obser ve the instructions on fitting and use
contained in the guide supplied with the
roof bars.
Direct installation on the
roof (Hatchback)You must only attach the transverse bars to
the four fixing points located in the roof frame.
These points are concealed by the door seals;
raise the seal to access the fixing point.

Maximum authorised load distributed over
the transverse roof bars, for a load height
not exceeding 40 cm (with the exception
of
bicycle carriers):
-
Hatchback: 65 kg.
-
SW: 80 kg .
For more information, contact a
PEUGEOT dealer or a qualified workshop.
If the height exceeds 40
cm, adapt the
speed of the vehicle to the profile of the
road to avoid damaging the roof bars and
the vehicle's fixing points.
For transporting objects which are longer
than the vehicle, refer to local legislation.
Recommendations
Distribute the load uniformly, taking care
to avoid overloading one of the sides.
Arrange the heaviest part of the load as
close as possible to the roof.
Secure the load firmly.
Drive gently: the vehicle will be more
susceptible to the effects of side winds
and its stability may be affected.
Regularly check the correct locking of the
roof bars, at least before each trip.
Remove the roof bars once they are no
longer needed.
If you use a roof box, contact a PEUGEOT
dealer or a qualified workshop to obtain
the compatible fixing parts. Sunroof
Do not operate the sunroof when using
roof bars – risk of major damage!
Bicycle/Accessory Carrier
Do not fit an accessory carrier to the
tailgate.

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 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

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.
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.
Topping up the engine oil level

switching on the ignition with the oil
level indicator in the instrument panel
is not
valid during the 30 minutes after
topping up.
Practical information

207
Changing the fluid
Refer to the manufacturer's service schedule
for details of the inter val for this operation.
Coolant level
Check the coolant level regularly.
It is normal to top up the fluid
between two services.
The check and top-up must only be done with
the engine cold.
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, wrap 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.
Screenwash fluid level
Top up to the required level when
necessary.
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 .) .
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.
Level of AdBlue
An alert is triggered once the reser ve level is
reached.
For more information on the Indicators for
the AdBlue range, refer to the corresponding
section.
To avoid the vehicle being immobilised as per
regulations, you must top up the AdBlue tank.
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. Filling with pure water is prohibited under all
circumstances (risk of freezing, limestone
deposits, etc.).

Practical information

208
For more information on AdBlue (BlueHDi
engines), and in particular on topping up the
tank, refer to the corresponding section.
Checks
Unless otherwise indicated, check these
components in accordance with the
manufacturer's service schedule.
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.
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.
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 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.
