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.
When filling the tank, do not continue after the
3
rd cut-off of the nozzle to avoid 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.
With a
BlueHDi Diesel engine, if the SCR
system is faulty, your vehicle becomes
polluting. As soon as possible, visit
a CITROËN dealer or a qualified workshop to
make your vehicle's level of nitrogen oxides
emissions compliant to the standard.

Indicators
Service information
For a few seconds after the ignition is
s witched on, the spanner symbolising ser vice
information comes on: the screen informs you
when the next ser vice is due, in accordance
with the ser vicing schedule indicated in the
manufacturer's service schedule.
Engine oil level
Depending on the engine, the engine oil level
then appears, graduated from 1 (Min.) to
5


( M a x .) .
If no graduation is displayed, the oil level is
too low; it is essential that you top up to avoid
damaging the engine.
For the oil level reading to be accurate, the
vehicle must be parked on level ground, with
the engine off for more than 30
minutes.
This information is determined in relation to the
distance travelled since the previous service. If in doubt, check the level with the
dipstick.
For more information on Checking levels
,
refer to the corresponding section.
Engine oil condition
This warning lamp flashes and,
if your vehicle has this function,
a message is displayed at every
engine start: the system has
detected deterioration of the engine
oil. Have the oil changed as soon as
possible.
This 2nd warning lamp, coupled with the
1st, comes on in the instrument panel
when the oil has not been changed and
the deterioration of the oil has gone
beyond a
new threshold. If this warning
comes on at regular inter vals, have the
oil changed as soon as possible.
For 3.0 litre HDi engines, the engine
s peed is restricted to 3,000 rpm, then
1,500
rpm until the oil is changed. Have
the engine oil changed to avoid any risk of
damage.
After a

few seconds, the display returns to its
usual functions.
Resetting the servicing
information
Refer to the list of checks in the
manufacturer's service schedule which
was given to you on handover of the
vehicle.

top immediately, switch off the ignition. The
fan may continue to operate for a
certain
time up to approximately 10
minutes.
-

w
ait for the engine to cool down in order to
check the level and top it up if necessary. When topping up:
Caution, the coolant circuit is pressurised!
In order to avoid any risk of scalding, place
a
cloth around the cap and unscrew the cap by
two turns to allow the pressure to drop.
When the pressure has dropped, remove the
cap to check the level and top up.
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 remains in the red zone,
contact a CITROËN dealer or a qualified
workshop.
Check the coolant level regularly.
For more information on Checking levels ,
refer to the corresponding section.
Fuel gauge
The fuel level is tested every time the ignition
is turned on.

To avoid the risks of poisoning or
asphyxia, the additional heating must
not be used, even for short periods, in
a closed environment such as a garage or
workshop which are not equipped with an
exhaust gas extraction system.
The additional heating switches off when
the battery voltage is low, so as to allow
engine starting.
The additional heating is fed by the
vehicle's fuel tank. Ensure that the low fuel
warning lamp is not on.
Always switch off the additional heating
when refuelling to avoid any risk of fire or
explosion!
The temperature near the heating
system must not exceed 120°C. A higher
temperature (e.g. when baking the
paint) could damage the components of
electronic circuits.
The additional heating is fitted with
a
temperature limiter which cuts off
the combustion in the event of engine
overheating due to a
lack of coolant.
Check the level and top up if necessary.
For more information on Checking levels ,
refer to the corresponding section.
Then press the programme selection
button before switching the heating on
again.Recommendations for ventilation and air conditioning
In order for these systems to be fully effective,
follow the operation and maintenance
guidelines below:
F

T
o ensure that the air is distributed evenly,
keep the external air intake grilles at the
base of the windscreen, the nozzles, the
vents, the air outlets and the air extractor
in the boot free from obstructions.
F

D
o not cover the sunshine sensor,
located on the dashboard; this is used for
regulation of the automatic air conditioning
system.
F

O
perate the air conditioning system for
at least 5
to 10 minutes once or twice
a
month to keep it in per fect working order.
F

E
nsure that the passenger compartment
filter is in good condition and replace
the filter elements periodically. We
recommend the use of a
combined
passenger compartment filter. Thanks to
its special active additive, it helps both to
purify the air breathed by the occupants
and to keep the passenger compartment
clean (reduction of allergic symptoms, bad
odours and greasy deposits). F
T o ensure correct operation of the
air conditioning system, you are also
advised to have it checked regularly as
recommended in the Maintenance and
Warranty Guide.
F

I
f the system does not produce cold air,
switch it off and contact a
CITROËN
dealer or a
qualified workshop.
When towing the maximum load on a
steep
gradient in high temperatures, switching off
the air conditioning increases the available
engine power and so improves the towing
ability.
To avoid the windows misting up and
deterioration in the quality of the air:
-

d
o not drive for too long with the
ventilation switched off.
-

d
o not keep air recirculation set for an
extended period.

Dynamic stability control (DSC)
If there is a difference between the path
f ollowed by the vehicle and that required by
the driver, the DSC monitors each wheel and
automatically acts on the brake of one or more
wheels and on the engine to return the vehicle
to the required path, within the limits of the laws
of physics.
Anti-lock braking system
(ABS) and electronic brake
force distribution (EBFD)
If this warning lamp comes on,
accompanied by an audible signal
and a
message in the instrument
panel screen, it indicates a
fault with
the anti-lock braking system (ABS)
which could result in loss of control
of the vehicle when braking.
If these warning lamps come on,
accompanied by a
message in the
instrument panel screen, it indicates
a
fault with the electronic brake force
distribution (EBFD) system which
could result in loss of control of the
vehicle when braking.
You must stop as soon as it is safe to do so.
In both cases, contact a
CITROËN dealer or
a


qualified workshop. For maximum braking efficiency, a
bedding-in period of around 310
miles
(500 kilometres) is needed. During this
period, it is advisable to avoid any sudden,
repeated and prolonged braking.
The ABS does not provide shorter braking
distances. On very slippery sur faces (ice,
oil, etc.) the ABS may extend braking
distances.
When changing wheels (tyres and rims),
make sure that these are approved for
your vehicle.
For emergency braking, press the
brake pedal ver y hard and do not
release it, even on a
slipper y sur face;
you will then be able to continue
steering the vehicle to avoid an
obstacle.
After an impact, have these systems
checked by a
CITROËN dealer or
a


qualified workshop.
Dynamic stability control
(DSC)
Switching on
The DSC system is activated automatically
each time the vehicle is started.
It comes into operation in the event of a grip or
trajectory problem.
This is indicated by this warning
lamp flashing in the instrument
panel.
Deactivation
This system cannot be deactivated by the
driver.
Malfunction
Illumination of this warning lamp,
accompanied by an audible signal
and confirmed by a message in the
instrument panel screen, indicates
a
fault with the DSC system.
Have it checked by a
CITROËN dealer or by
a


qualified workshop.
