Instruments

187
The vehicle is fitted with a catalytic converter
which reduces harmful substances in the
exhaust gases.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- of f
Your vehicle is fitted with a safety system that
cuts off the supply of fuel in the event of an
impact.
Diesel misfuel prevention
Mechanical device which prevents filling the
tank of a Diesel vehicle with petrol. It helps
avoid 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. It is still possible to use a fuel can to fill the
t a n k s l ow l y.
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.Driving 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 CITROËN dealer network,
whether your vehicle is suitable for the
fuel pumps in the country in which you
intend to travel.
When a petrol filler nozzle is introduced into the
fuel filler neck of your Diesel vehicle, it comes
into contact with the flap. The system remains
closed and prevents filling.
Do not persist but introduce a Diesel type
filler nozzle.
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 specific to
each country on the use of snow chains
and the maximum authorised speed.

Practical information

Wheels and tyres
The pressure must be checked on
all tyres, including the spare wheel,
when the tyres are "cold".
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.
Driving with under-inflated tyres 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
the braking and road holding per formance of
the vehicle. It is recommended to regularly
check the condition of the tyres (tread and
sidewalls) and wheel rims as well as the
presence of the valves.
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.
AdBlue® (BlueHDi)
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, CITROËN
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 liquid called AdBlue® that contains
urea, a catalytic converter turns up to 85%
of nitrogen oxides (NOx) into nitrogen and
water, which are harmless to health and the
environment.
The AdBlue
® is contained in
a special tank holding about
20


litres. Its capacity allows a driving range of
approximately 4,300
miles (7,000 km)
( highly dependent on your driving style
and the vehicle). An alert system is triggered
automatically when the remaining range
reaches 1,500 miles (2,400 km), i.e. once the
reserve level has been reached.
Several alerts are triggered successively during
the remaining 1,500 miles (2,400 km) before
the tank is empty and the vehicle is disabled.
If the estimated distance travelled by the
vehicle between two ser vices is greater than
3,700 miles (6,000 km), it will be necessary to
top up the AdBlue.
For more information on the Warning
and indicator lamps and the associated
alerts, or the Indicators , refer to the
corresponding sections.
Fitting different tyres on the front and rear axles
can cause the ESC to mistime.
