MONITORING










Warning lamps
When the engine is running or the vehicle is being driven, the illumination of one of the following warning lamps indicates
a fault which requires action on the part of the driver.
Any fault resulting in the illumination of a warning lamp must be investigated further by reading the associated message
in the multifunction screen.
If you encounter any problems, do not hesitate to contact a CITROËN dealer or a qualifi ed workshop.

Cause


Action/Observations






STOP


fi xed, associated
with another
warning lamp. It is associated with a
punctured tyre or the engine
coolant temperature. Stop as soon as it is safe to do so.
Park, switch off the ignition and call a
CITROËN dealer or a qualifi ed workshop.





Service


temporarily. A minor fault has occurred
for which there is no specifi c
warning lamp. Identify the fault by reading the message
shown in the screen, such as, for example:


- the closing of the doors, boot, rear
screen or bonnet,

- the remote control battery,

- the tyre pressures,

- saturation of the particle emission fi lter
(Diesel).
For any other faults, contact a CITROËN
dealer or a qualifi ed workshop.

fi xed. A major fault has occurred
for which there is no specifi c
warning lamp. Identify the fault by reading the message
shown in the screen and contact a
CITROËN dealer or a qualifi ed workshop.

Cause


Action/Observations





Maximum
coolant
temperature


fi xed red. The temperature of the
cooling system is too high. Stop as soon as it is safe to do so.
Wait until the engine has cooled down
before topping up the level, if necessary.
If the problem persists, contact a
CITROËN dealer or qualifi ed workshop.




Battery
charge


fi xed. The battery charging circuit
has a fault (dirty or loose
terminals, slack or cut
alternator belt, ...). The warning lamp should go off when the
engine is started.
If it does not go off, contact a CITROËN
dealer or a qualifi ed workshop.





Door(s) open


fi xed if the speed
is below 6 mph
(10 km/h).
A door, the boot or the rear
screen is still open. Close the door or boot.
fi xed and
accompanied by
an audible signal
if the speed is
above 6 mph
(10 km/h).




Seat belts
not fastened/
unfastened


fi xed. The driver and/or the front/
rear passenger has not
fastened or has unfastened
their seat belt.
Pull the strap then insert the tongue in the buckle.
The illuminated dots represent the
passengers that have not fastened/
unfastened their seat belt.
They come on:


- fi xed for 30 about seconds on starting
the vehicle,

- fi xed from 0 to 12 mph (0 to 20 km/h)
when driving,

- fl ashing above 12 mph (20 km/h),
accompanied by an audible signal for
about 120 seconds.

CHECKS




















Screenwash and headlamp wash
fl uid

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











Diesel additive level (Diesel
engine with particle emission
filter)
A low additive level is indicated by
illumination of the service warning
lamp, accompanied by an audible
warning and a message in the multi-
function screen.

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 uids 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.
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.











Coolant level


Changing the coolant
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 temperature of the coolant is
regulated by the fan. This can ope-
rate 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
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, un-
screw the cap by two turns to al-
low the pressure to drop. When the
pressure has dropped, remove the
cap and top up the level.

PRACTICAL INFORMATION

Towbar suitable for the attachment
of a trailer 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.
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 or a qualifi ed
workshop.
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.
Refer to the "Technical Data" section
for details of the weights and towed
loads which apply to your vehicle.

Side wind


)
Take into account the increased
sensitivity to side wind.


)
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.


)
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.
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.
Driving with a trailer places greater
demands on the towing vehicle and
the driver must take particular care.

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.
