AT A GLANCE
Limit the causes of excess consumption
Spread loads throughout the vehicle; place the heaviest items in
the bottom of the boot, as close as possible to the rear seats.
Limit the loads carried in the vehicle and reduce wind resistance
(roof bars, roof rack, bicycle carrier, trailer...). Use a roof box in
preference.
Remove roof bars and roof racks after use.
At the end of winter, remove snow tyres and refit your summer
tyres.
Observe the recommendations on maintenance
Check the tyre pressures regularly, when cold, referring to the
label in the door aperture, driver's side.
Carry out this check in particular:
- before a long journey,
- at each change of season,
- after a long period out of use.
Don't forget the spare wheel and the tyres on any trailer or
caravan.
Have your vehicle serviced regularly (engine oil, oil filter, air
filter, cabin filter...) and observe the schedule of operations in the
maintenance and warranty guide.
When refuelling, do not continue after the 3
rd cut-off of the nozzle
to avoid any overflow.
At the wheel of your new vehicle, it is only after the fi rst 1 800 miles
(3 000 kilometres) that you will see the fuel consumption settle
down to a consistent average.

Instruments and controls
FUEL GAUGE

The fuel level is tested every time the
ignition is turned on.
The gauge is positioned on:
- F (Full): the fuel tank is full, approximately 90 litres.
- E (Empty): the reserve is now being used, the low fuel warning lamp comes
on continuously.
The reserve when the warning first comes
on is approximately:
- 10 litres for 60 and 90 litre tanks,
- 12 litres for 125 litre tanks.
Fuel tanks of different capacities (60 and
125 litres) are available as an option.
COOLANT TEMPERATURE
The needle is positioned between
C (Cold) and H (Hot): normal operation.
In arduous conditions of use or hot climatic
conditions, the needle may move close to
the red graduations. If the needle enters the red zone or if the
warning lamp comes on:

- stop immediately, switch off the ignition. The fan may continue to operate for a
certain time up to approximately
10 minutes.
- wait for the engine to cool down in order to check the level and top it up if
necessary. Follow this advice:
the cooling system is pressurised. In order
to avoid any risk of scalding, unscrew the
cap by two turns to allow the pressure
to drop.
When the pressure has dropped, check the
level and remove the cap to top-up.
If the needle remains in the red zone,
contact a CITROËN dealer or a qualified
workshop.
Refer to the "Checks - Fuel" section. Refer to the "Checks - Levels and
checks" section.

Instruments and controls
EMISSIONS CONTROLS
EOBD (European On Board Diagnosis) is
a diagnostics system which complies with,
among others, the standards concerning
authorised emissions of:
- CO (carbon monoxide),
- HC (unburnt hydrocarbons),
- NOx (nitrous oxides) or particles, detected by oxygen sensors placed
upstream and downstream of the
catalytic converters.
TYRE UNDER-INFLATION DETECTION
System which automatically checks the
pressures of the tyres while driving.
The tyre under-inflation detection
system is an aid to driving which does
not replace the need for the driver to be
vigilant or to drive responsibly. This system does not avoid the need
to check the tyre pressures regularly
(including the spare wheel) and before a
long journey.
Driving with under-inflated tyres adversely
affects road holding, extends braking
distances and causes premature tyre
wear, particularly under arduous conditions
(vehicle loaded, high speed, long journey).
Driving with under-inflated tyres
increases fuel consumption.
The system continuously monitors the
pressures of the four tyres, as soon as the
vehicle is moving.
A pressure sensor is located in the valve of
each tyre (except the spare wheel).
The system triggers an alert if a drop in
pressure is detected in one or more tyres. The tyre pressures must be checked
when the tyres cold (vehicle stopped
for 1 hour or after driving for less then
6 miles (10 km) at moderate speed).
Otherwise, add 0.3 bar to the values
indicated on the label.
The tyre pressures for your vehicle can be
found on the tyre pressure label.
The driver is warned of any
malfunction of this emission
control system by the illumination
of this specific warning lamp in
the instrument panel.
There is a risk of damage to the catalytic
converter. Have it checked by a CITROËN
dealer or a qualified workshop.
Refer to the "Technical data -
Identification markings" section.
