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, etc.). Preferably, use a
roof box.
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:
-
b
efore a long journey,
-

a
t each change of season,
-

a
fter a long period out of use.
Do not forget the spare wheel and the tyres on
any trailer or caravan. Have your vehicle ser viced regularly (engine
oil, oil filter, air filter, cabin filter, etc.) and
obser ve the schedule of operations in the
manufacturer's service schedule.
With a BlueHDi Diesel engine, if the SCR
system is faulty, your vehicle becomes
polluting. Visit a CITROËN dealer or a
qualified workshop as soon as possible to
bring your vehicle's nitrogen oxides emissions
back in line with the regulations.
When refuelling, do not continue after the 3
rd
cut-off of the nozzle to avoid any over flow.
At the wheel of your new vehicle, it is only
after the first 1,900 miles (3,000 kilometres)
that you will see the fuel consumption settle
down to a consistent average.

Warning and indicator
lamps
Displayed as symbols, visual indicators
which inform the driver of the occurrence of a
malfunction (warning lamps) or of the operation
of a system (operation or deactivation indicator
lamps). Certain lamps light up in two ways
(fixed or flashing) and/or in several colours.
Associated warnings
The illumination of a lamp may be accompanied
by an audible signal and/or a message
displayed in a screen.
Relating the type of illumination to the
operating status of the vehicle can determine
whether the situation is normal or a fault has
occurred: refer to the description of each lamp
for further information.
When the ignition is switched on
Certain red or orange warning lamps come on
for a few seconds when the ignition is switched
on. These warning lamps should go off as soon
as the engine is started.
Persistent warning lamp
When the engine is running or the vehicle is
being driven, the illumination of a red or orange
warning lamp indicates a fault that needs
further investigation, using any associated
message and the description of the warning
lamp in the documentation.
Where a warning lamp remains lit
The references (1) , (2) and (3) in the warning
lamp description indicate whether you should
contact a qualified professional in addition to
the immediate recommended actions.
