WARNING LIGHTS Each time the engine is started: a series of warni ng lights comes on applying a self-checking test. T hey switch off almost immediately.
When the engine is running: the warning light becom es a warning sign if it remains on continuously or flashes. This initial warning may be
accompanied by an audible signal and a message on t he display. "Do not ignore these warnings."

FUEL GAUGE
The fuel level is tested each time the key is
turned to the "running" position.
The gauge is positioned on:
- F (Full): the capacity of the fuel tank is
approximately 45 litres .
- E (Empty): the reserve is now being
used, the warning light comes on
continuously.
The reserve when the warning first comes
on is approximately 6 litres.
COOLANT TEMPERATURE
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.
-wait for approximately 15 minutes to allow the engine to cool down, then check the level and if necessary top up. The cooling circuit is pressurised. In order to avoid any risk of burns, unscrew the cap 2 turns to release the pressure.
When the pressure has dropped, check the level and remove the cap to top up. If the needle remains in the red zone, contact a CITROËN dealer
EMISSION CONTROL
EOBD (European On Board Diagnosis) is
a diagnostics system which complies with,
among others, the standards concerning
authorised emissions of:
- CO (carbon monoxide),
- HC (unburnt hydrocarbons),
- NOx (nitrogen oxides) or particles
detected by oxygen sensors placed
upstream and downstream of the catalytic
converters.
Refer to the "Levels" section of
chapter 7.
Refer to the "Levels" section of
chapter 7.
Therefore, the driver is warned of
any malfunction of this emission
control system by the flashing of
this specific warning light on the
instrument panel.
What you should do if the needle
enters the red zone, or if the warning
light comes on:
- stop immediately, switch off the ignition.
The fan may continue to operate for
a certain time up to approximately
10 minutes.

ACCESSORIES
Towing a trailer
TOWING A TRAILER, CARAVAN, BOAT, ETC.
Driving advice
A towed vehicle must free wheel: gearbox in
neutral.
Cooling: towing a trailer on a slope
increases the coolant temperature.
As the fan is electrically controlled, its
cooling capacity is not dependent on the
engine speed.
On the contrary, use a high gear to lower the
engine speed and reduce your speed.
In all cases, pay attention to the coolant
temperature.

102
Towing a trailer
In certain cases of particularly arduous
use (towing the maximum load up a steep
slope in high temperatures), the engine
automatically limits its power. In this
case, the automatic cutting off of the air
conditioning allows the engine power to be
recovered.
If the coolant temperature
warning light comes on, stop the
vehicle and switch off the engine
as soon as possible.
See the "Levels" section of chapter 7.
Tyres: check the tyre pressures of the
towing vehicle (see the "Identification
features" section of chapter 7) and of
the trailer, observing the recommended
pressure.
Brakes: towing increases the braking
distance. Drive at a moderate speed,
change down early and brake gradually.
Side wind: sensitivity to side wind is
increased. Drive smoothly and at a
moderate speed.
ABS: the system only controls the vehicle,
not the trailer.
Rear parking assistance:
the assistance will be deactivated
automatically when a CITROËN towbar is
used (see the "Rear parking assistance"
section of chapter 4).
Towbar
We recommend the use of CITROËN
towbars and their harnesses, which have
been tested and approved from the design
stage of your vehicle, and that the fitting of
this equipment is entrusted to a CITROËN
dealer .
If this equipment is not fitted by a CITROËN
dealer , it is essential that it is fitted using
the electrical pre-equipment located at the
rear of the vehicle in accordance with the
manufacturer ’s instructions.
The operation of the sensors is deactivated
automatically when the pin of the trailer
cable is inserted in the towbar socket.
When the trailer cable pin is removed, the
sensors are re-activated.
Distribution of loads
Distribute the load in the trailer so that the
heaviest objects are as close as possible
to the axle and the nose weight is close to
the maximum authorised without, however,
exceeding it. The air density decreases with
altitude, so reducing the performance of
the engine. The maximum towed load must
be reduced by 10 % for each 1 000 metres
of altitude. Refer to the "Technical data"
chapter for details of the weights and towed
loads applicable to your vehicle and also to
the administrative documents
(V5 registration document, etc.).

Levels

Cooling system
Only use the fluid recommended by the
manufacturer. Otherwise, you risk seriously
damaging your engine. When the engine
is warm, the temperature of the coolant is
controlled by the engine fan. As this fan can
operate with the ignition key removed and
because the cooling system is pressurised,
wait for at least one hour after the engine
has stopped before carrying out any work.
To avoid any risk of burns, unscrew the cap
2 turns to release the pressure. When the
pressure has fallen, remove the cap and top
up the level with coolant.
If fluid has to be added frequently, this
indicates a failure which must be checked by
a CITROËN dealer as soon as possible.
Topping up
The level must be between the MIN and

MAX marks on the expansion bottle. If
more than 1 litre of fluid is required to top
up the level, have the system checked by a
CITROËN dealer .

Power steering fluid level
The vehicle must be parked on level ground with
the engine cold. Unscrew the cap integrated with
the gauge and check the level which must be
between the MIN and MAX marks.

Windscreen wash level
For best quality cleaning and for your safety,
we would advise that you use products of
the CITROËN Universal range.
Capacity of the reservoir: approximately
5.5 litres.
Used oil
Avoid prolonged contact of used oil with the
skin.
Brake fluid is harmful to health and very
corrosive.
Do not dispose of used oil, brake fluid or
coolant into drains or into the ground but
into the containers dedicated to this use at a
CITROËN dealer .
