If you have put in the wrong fuel for
your vehicle, you must have the fuel
tank drained and filled with the correct
fuel before star ting the engine.
Fuel cut-off
Your vehicle is fitted with a safety system that
cuts off the supply of fuel in the event of an
impact.
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 dealer network whether your
vehicle is suitable for the fuel pumps in the
country in which you intend to travel.

Compatibility of fuels
Fuel used for petrol engines
The petrol engines are compatible with biofuels
that conform to current and future European
standards and which can be obtained from
filling stations:Petrol that meets standard EN228,
mixed with a biofuel that meets
standard EN15376.
The only petrol additives authorised for
use are those that meet the B715001
standard.
Fuel used for Diesel engines
The Diesel engines are compatible with
biofuels that conform to current and future
European standards and which can be
obtained from filling stations. Diesel fuel that meets standard
EN590 mixed with a biofuel that
meets standard EN14214 (possibly
containing 0 to 7% Fatty Acid Methyl
Ester), For more information, contact the dealer
network or a qualified workshop.Diesel fuel that meets standard
EN16734 mixed with a biofuel that
meets standard EN14214 (possibly
containing 0 to 10% Fatty Acid
Methyl Ester),
Paraffinic Diesel fuel that meets
standard EN15940 mixed with
a biofuel that meets standard
EN14214 (possibly containing 0 to
7% Fatty Acid Methyl Ester).
The use of B20 or B30 fuel meeting
standard EN16709 is possible in
your Diesel engine. However, this
use, even occasional, requires strict
application of the special ser vicing
conditions referred to as "Arduous
conditions".
The use of any other type of (bio)fuel
(vegetable or animal oils, pure or diluted,
domestic fuel...) is strictly prohibited (risk
of damage to the engine and fuel system). The only Diesel additives authorised for
use are those that meet the B715000
standard.
Diesel at low temperature
At temperatures below 0°C (+32°F), the
formation of paraffins in summer-type Diesel
fuels could entail an abnormal operation
of the fuel supply circuit. To avoid this, we
recommend using winter-type Diesel fuel and
keeping the fuel tank more than 50% full.
If, despite this, at temperatures below -15°C
(+5°F) the engine has problems starting,
just leave the vehicle in a garage or heated
workshop for a little while.
Travelling abroad
Certain fuels could damage the engine of your
vehicle.
In certain countries, the use of a particular
fuel may be required (specific octane rating,
specific sales name…) to ensure correct
operation of the engine.
For any additional information, contact the
dealer network.

Snow chains
In wintry conditions, snow chains improve
traction as well as the behaviour of the vehicle
when braking.The snow chains must be fitted only to the
front wheels. They must never be fitted to
"space-saver" type spare wheels.
Take account of the legislation in force in
your country on the use of snow chains
and the maximum authorised speed.
Installation tips
F If you have to fit the chains during a journey, stop the vehicle on a flat sur face on the side
of the road.
F

A
pply the parking brake and if necessary
put wheel chocks against the wheels to
prevent your vehicle from sliding.
F

F

provided by the manufacturer.
F

M
ove off gently and drive for a few
seconds, without exceeding around 30 mph
(50


km/h).
F

S
top your vehicle and check that the snow
chains are correctly tightened.
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 fixtures is in contact with the
wheel rim.
It is strongly recommended that before
you leave, you practise fitting the snow
chains on a level and dry sur face. Only use the chains designed to be fitted to the
type of wheels fitted to your vehicle:
Original tyre size Maximum link size
215/60 R16 9 mm
215 / 5 5 R17
225/45 R18
225/40 R19
cannot be fitted with chains
For more information on snow chains, contact
the dealer network or a qualified workshop.

a
t speeds above 75 mph (120 km/h).
To w b a r
Your vehicle is primarily designed for
transporting people and luggage, but it may
also be used for towing a trailer.We recommend the use of genuine
DS AUTOMOBILES towbars and their
harnesses that have been tested and
approved from the design stage of your
vehicle, and that the fitting of the towbar
is entrusted to a dealer or a qualified
workshop.
If the towbar is not fitted by a dealer, it
must still be fitted in accordance with the
vehicle manufacturer's instructions. Driving with a trailer places greater
demands on the towing vehicle and the
driver must take particular care.
For more information on Driving advice
,
particularly when towing, refer to the
corresponding section.
Obser ve the maximum authorised towable
weight, indicated on your vehicle's
registration certificate, the manufacturer's
label as well as in the Technical data
section of this guide.
Complying with the maximum
authorised nose weight (towball)
also includes the use of accessories
(bicycle carriers, tow boxes, etc.).
The maximum authorised nose weight
does not depend on the type of device
installed, fixed or removable, with or
without a tool.
