WARNING LAMPS
Each time the engine is started: a series of warning lamps comes on applying a self-checking test. Th ey go off almost immediately. When
the engine is running: the warning lamp becomes a w arning sign if it remains on continuously or flashes. This initial warning may be
accompanied by an audible signal and a message in t he screen. "Do not ignore these warnings".

Instruments and controls
FUEL GAUGE
The fuel level is tested each time the key is
turned to the "ignition on" 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 lamp 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 approximately 15 minutes to allow
the engine to cool down in order to check
the level and top it up if necessary. The
cooling system is pressurised. In order to
avoid any risk of scalding, unscrew the
cap by two turns to allow the pressure to
drop.
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 meets the exhaust
emissions standards for:
- CO (carbon monoxide),
- HC (unburnt hydrocarbons),
- NOx (nitrous 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.
The driver is warned of any
fault with this emission control
system by flashing of this specific
warning lamp in the instrument
panel.

What you should do if the needle
enters the red zone, or if the warning
lamp comes on:
- stop immediately, switch off the ignition. The cooling fan may continue to operate
for a certain time up to approximately
10 minutes.

Towing a trailer
TOWING A TRAILER, CARAVAN, ETC...
Driving advice 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.
A towed vehicle must free wheel: gearbox in
neutral.

Cooling: towing a trailer on a slope
increases the coolant temperature.

ACCESSORIES
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,
automatic cutting off of the air conditioning
allows the engine power to be saved.
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
markings" section of chapter 7) and of
the trailer, observing the recommended
pressures.

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 sensors: the sensors
will be deactivated automatically
when an genuine CITROËN towbar is used
(see the "Rear parking sensors" section of
chapter 3). Towbar
We recommend the use of original
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 and following the
manufacturer's instructions.
The operation of the rear parking sensors is
deactivated automatically when the trailer
cable connector is inserted in the towbar
socket.
When the trailer cable is removed, the rear
parking 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, ...).

Levels
Engine coolant level
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 cooling 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.
Topping up
The level must be between the MIN and

MAX marks on the header tank. 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 with
integral gauge and check the level which
must be between the
MIN and MAX marks.
Screenwash fluid level
For optimum cleaning and to avoid freezing,
topping up or replacement of this fluid
should never be with plain water; we
recommend the use of products available
from CITROËN dealers.
Capacity of the reservoir: approximately
5.5 litres.
Slacken the cap by two turns to release the
pressure to prevent any risk of scalding.
When the pressure has dropped, remove the
cap and top up the level with coolant.
If fluid has to be added frequently, this
indicates a fault which must be checked by a
CITROËN dealer as soon as possible. Used products
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 provided for this
purpose at CITROËN dealers (France) or
at an authorised waste disposal site.
