FAMILIARISATION

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, passenger
compartment filter...) and observe the
schedule of operations recommended in the
maintenance and warranty guide. When refuelling, do not continue after the
third 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.

FUEL GAUGE
The fuel level is tested each time the key is
turned to the "running" position.
The gauge is positioned on:
- 1: the fuel tank is full, approximately 80 litres.
- 0: the reserve is now being used, the warning lamp comes on continuously.
COOLANT TEMPERATURE
The needle is positioned before the red
zone: normal operation.
In arduous conditions of use or hot climatic
conditions, the needle may move close to
the red graduations. What you should do 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 coolant level and top it up if
necessary.
Refer to the "Fuel" section of chapter 6. What you should do if the needle enters
the red zone:

Reduce your speed or let the engine run at
idle. Refer to the "Levels" section of
chapter 6.
The reserve when the warning first comes
on is approximately 8 litres. As the cooling system is pressurised, follow
this advice in order to avoid any risk of
scalding:
- wait at least one hour after switching off
the engine before carrying out any work,
- unscrew the cap by 1/4 turn to allow the pressure to drop,
- when the pressure has dropped, check the level on the expansion bottle,
- if necessary, remove the cap to top up.
If the needle remains in the red zone, have
the system checked by a CITROËN dealer
or a qualified workshop.

Instruments and controls
EMISSIONS CONTROLS
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.
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. EOBD (European On Board
Diagnosis) is a diagnostics
system which complies with,
among others, the standards
TYRE UNDER-INFLATION DETECTION
System which automatically checks the
pressures of the tyres while driving.
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 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 tyre pressures for your vehicle can
be found on the tyre pressure label
(see the "Identification markings" section).
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.
