Engine autodiagnostics system If this comes on, it indicates
the occurrence of a fault in
the engine management
system.
If it fl ashes, it indicates the occurrence of
a fault in the emission control system.
Maximum coolant temperature If this comes on, it indicates
that the temperature in the
cooling system is too high.
Stop the vehicle immediately
and as safely as possible.
Check the coolant level.
If the level is low, contact a CITROËN
dealer.
Fuel low
If this comes on, it indicates
that the range remaining
is approximately 30 miles
(50 km).
It may be less than this in certain
driving conditions and depending on
the engine.
The capacity of the tank is approxi-
mately 71 litres. Battery charge
If this comes on, it indi-
cates the occurrence of a
fault in the battery charging
circuit (dirty or loose termi-
nals, slack or cut alternator
belt...).
Seat belt not fastened/
unfastened *
* According to country.
This warning lamp lights
up on the instrument panel
to remind the driver and all
passengers that they must
fasten their seat belt.
It is linked to the seat belt informa-
tion given by the roof console. Seat belt non-fastening/
unfastening
This warning lamp
informs you of the
non-fastening and
unfastening of the
driver and passenger seat belts.
The illuminated positions represent
the passengers whose seat belts
are not fastened/unfastened.
Driver’s seat belt not fastened:
- The warning lamp lights up be- tween 0 and 12 mph (20 km/h).
Above 12 mph, it fl ashes ac-
companied by a sound signal for
around 120 seconds.
Front and rear passenger seat belts
not fastened:
- When the ignition is switched on, the points corresponding to
the seat positions with seat belts
not fastened remain lit up for
30 seconds.
Seat belts unfastened during the
journey:
- The point corresponding to the seat position with seat belt un-
fastened lights up between 0 and
12 mph (20 km/h). Above
12 mph, it fl ashes accompanied
by an audible signal for around
120 seconds. The audible signal
stops when the seat belt is re-
fastened or if a door is opened.

Engine oil temperature gauge
Under normal operating conditions,
the bars should be within section 1 .
In severe operating conditions, the
bars may extend into section 2 .
In this event, slow down, and if neces-
sary, stop the engine and check the
levels (see corresponding chapter). Coolant temperature
indicator
Under normal operating conditions,
the bars should be within section
1 .
In severe operating conditions, the
bars may extend into section 2 , the
engine coolant temperature warning
lamp A and the STOP warning lamp
will light up, stop immediately . Switch
off the ignition. The cooling fan may
continue to operate for a certain
time .
Consult a CITROËN dealer.
If the SERVICE warning lamp lights
up, check the levels (see correspon-
ding chapter). On horizontal ground, the lighting of
the fuel low warning lamp warns you
that you are at the reserve level.
A message alert is displayed on the
instrument panel.

Screenwash and headlamp
wash fluid
Fluid specifi cation

For optimum cleaning and to avoid free-
zing, this fl uid must not be topped up or
replaced with water.
Reservoir capacities:
- screenwash: approximately 3.5 litres,
- screenwash and headlamp wash: approximately 6.15 litres.
Diesel additive level (Diesel
engine with particle emission
filter)
A low additive level is indicated by
lighting of the service warning lamp,
accompanied by an audible warning
and a message on the multifunction
screen.
Topping up
This additive must be topped up by
a CITROËN dealer without delay.
Used products
Avoid prolonged contact of
used oil or fl uids with the
skin.
Most of these fl uids are harmful to
health or indeed very corrosive.
Do not discard used oil or
fl uids into sewers or onto
the ground.
Take used oil to a an authorised
waste disposal site CITROËN.
In the case of vehicles fi tted
with headlamp washers, the
minimum level of this fl uid is
indicated by an audible signal
and a message on the multifunction
screen.
Top up the level when you stop the
vehicle.
Coolant level
Coolant change
The coolant does not have to be
changed.
Fluid specifi cation
The coolant must conform to the
manufacturer’s recommendations. The coolant level should be
close to the "MAX" mark but
should never exceed it.
When the engine is warm, the tem-
perature of the coolant is regulated
by the fan. This can operate with the
ignition off.

On vehicles which are fi tted with
a particle emission fi lter, the fan
may operate after the vehicle has
been switched off, even if the en-
gine is cold.
In addition, as the cooling system is
pressurised, wait at least one hour
after switching off the engine before
carrying out any work.
To avoid any risk of scalding, unscrew
the cap by two turns to allow the pres-
sure to drop. When the pressure has
dropped, remove the cap and top up
the level.

TOWING A TRAILER, A CARAVAN, ETC.
Towbar suited to the attachment of a
trailer or caravan with additional sig-
nalling and lighting.
Your vehicle is primarily designed
for transporting people and luggage,
but it may also be used for towing a
trailer.
We recommend the use of genuine
CITROËN towbars and their har-
nesses that have been tested and
approved from the design stage
of your vehicle, and that the fi t-
ting of the towbar is entrusted to a
CITROËN dealer. If the trailer is not fi tted by
a CITROËN dealer, it is
imperative that it is fi tted
using the electrical pre-equipment
installed at the rear of the vehicle,
in accordance with the manufactur-
er’s instructions.
Driving with a trailer subjects the
towing vehicle to more signifi cant
stress and its driver must be par-
ticularly careful.
Driving advice
Distribution of loads

 Distribute the load in the trailer
so that the heaviest items are as
close as possible to the axle and
the nose weight approaches the
maximum permitted without ex-
ceeding it.
Air density decreases with altitude,
thus reducing engine performance.
Above 1 000 metres, the maximum
towing load must be reduced by 10 %
and so on for every 1 000 metres of
altitude.
Refer to the "Technical Data" section
for details of the weights and towing
loads which apply to your vehicle.
Side wind

 Take into account the increased
sensitivity to side wind. Cooling
Towing a trailer on a slope increases
the temperature of the coolant.
As the fan is electrically controlled,
its cooling capacity is not dependent
on the engine speed.

 To lower the engine speed, reduce
your speed.
The maximum towing load on a long
slope depends on the gradient and
the ambient temperature.
In all cases, pay attention to the
coolant temperature.

 If the warning lamp and
the STOP warning lamp
come on, stop the vehicle
and switch off the engine
as soon as possible.
Braking
Towing a trailer increases the brak-
ing distance.
Tyres

 Check the tyre pressures of the
towing vehicle and of the trailer,
observing the recommended
pressures.
Lighting

 Check the electrical signalling on
the trailer.
The rear parking assistance will
be deactivated automatically if an
original CITROËN towbar is used.

SNOW GUARD *
Moveable device which prevents the
accumulation of snow by the radia-
tor cooling fan.
Fitting

 Bring the 2 sections of the snow
guard up to the upper and lower
sections of the front bumper.

 Press on the surround to clip in
one by one the fi xing clips.
Remove

 Using a screwdriver, lift it up to
detach each fi xing clip one by one.
Before fi tting

After fi tting
It is essential to remove the snow
guard:
- When the outside temperature exceeds 10 °C,
- When towing,
- When driving at speeds of over 75 mph (approximately 120 km/h ).
