Diesel additive level
(Diesel engine with particle
emission filter)

Topping up
This additive must be topped up by
a CITROËN dealer or a qualifi ed
workshop 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 u-
ids into sewers or onto the
ground.
Take used oil to a CITROËN dealer
or a qualifi ed workshop (France) or
to an authorised waste disposal
site. The additive reservoir
low level is indicated
by fi xed illumination
of this warning lamp,
accompanied by an audible warning
and a message in the multifunction
screen.










Coolant level


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.

Changing the coolant
The coolant does not have to be
changed.

Fluid specifi cation
The coolant must conform to the
manufacturer's recommendations.






For vehicles fi tted with a particle
emissions fi lter, the cooling fan may
continue to run after stopping the
vehicle, even if the engine 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.






















Screenwash and headlamp
wash fluid


In the case of vehicles fi tted
with headlamp washers, the
low fl uid level is indicated
by an audible signal and a
message in the screen.
Top up the reservoir when you next
stop the vehicle.

Fluid specifi cation
For optimum cleaning and to avoid
freezing, this fl uid must not be
topped up with or replaced with plain
water.



Reservoir capacity (depending on
version).


- screenwash fl uid: approximately
3.5 litres,

- screenwash and headlamp wash
fl uid: approximately 6.15 litres.

PRACTICAL INFORMATION
TOWING A TRAILER

Towbar suitable for the attachment
of a trailer or installation of a bicycle
carrier, with additional lighting and
signalling.

Your vehicle is primarily designed
for transporting people and luggage,
but it may also be used for towing a
trailer.

If the towbar is not fi tted by a
CITROËN dealer, it is imperative
that it is fi tted in accordance with
the vehicle manufacturer's instructions.


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
towed load must be reduced by 10 %
for every 1 000 metres of altitude.

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, re-
duce your speed. The maximum towed load on a long
incline depends on the gradient and
the ambient temperature.
In all cases, keep a check on the
coolant temperature.

Braking
Towing a trailer increases the brak-
ing distance.
To avoid overheating of the brakes
on a long mountain type of descent,
the use of engine braking is recom-
mended.

Tyres


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


Lighting


)
Check the electrical lighting and
signalling on the trailer.


The rear parking sensors will be
deactivated automatically if a gen-
uine CITROËN towbar is used.


)
If the warning lamp and
the STOP
warning lamp
come on, stop the vehicle
and switch off the engine
as soon as possible.


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 tting of the
towbar is entrusted to a CITROËN
dealer or a qualifi ed workshop.

Driving with a trailer places great-
er demands on the towing vehicle
and the driver must take particular
care.

Refer to the "Technical Data" section
for details of the weights and towed
loads which apply to your vehicle.
