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.
The roof bar fixings include a lug to be fitted in
the pin of each 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.
