WARNING LIGHTS

Each time the engine is started: a series of warning lights comes on applying a self-test check. They switch off almost
immediately. With the engine running: the warning light becomes a warning if it remains on continuously or fl ashes. This
initial warning may be accompanied by an audible signal and a message which appears on the display. "Do not ignore
these warnings."

In the event of a breakdown and in
order to avoid any risk of scalding,
unscrew the cap two turns to allow
the pressure to drop.
When the pressure has dropped,
remove the cap and top up the level.

INSTRUMENT PANEL DISPLAY

After switching on the ignition, three
functions are shown in succession:


- service indicator,

- engine oil level indicator
(see corresponding section),

- total distance recorder
(total and trip distances).
It also displays the automatic gearbox
positions and programmes selected
(see opposite).
The total and trip distances are
displayed for thirty seconds, when
the ignition is switched off, on
opening the driver’s door as well as on
locking and unlocking the vehicle.

Towing a trailer

ACCESSORIES
5
TOWING A TRAILER, CARAVAN, BOAT, ETC...


Refer to the administrative
documents (V5, ...) or to the Diesel
"Dimensions, weights and towed
loads" section of chapter 8.
Distribution of loads:
distribute the
load in the trailer so that the heaviest
loads are as close as possible to the
axle and the nose weight is close
to the maximum authorised without,
however, exceeding it.
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.
Dimension A
= 0.96 m


Driving advice

A towed vehicle must free wheel:
gearbox in neutral.

104


Towing a trailer

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.
Brakes:
towing increases the braking
distance. Drive at a moderate speed,
change down early and brake
gradually.


Automatic adjustment
For vehicles with Xenon bulbs, and if
the change in load makes it necessary,
this system automatically corrects the
height of the beam after approximately
2 minutes. The driver is then assured
of having optimum lighting and not
causing a nuisance to other road
users.


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, cutting off the air conditioning
allows the engine power to be
recovered, and therefore the towing
speed to be signifi cantly increased
(approximately 12 mph [20 km/h]
more). Sequential control of the
gearbox may also become unavailable.

Lighting

Bicycle carrier

Refer to the "Identifi cation
features" section of chapter 8. Refer to the "Steering wheel
controls" section of chapter 3.
When using a trailer connection,
you must add a fuse. Refer to
the "Changing a fuse" section of
chapter 7.




If the coolant temperature warning light
comes on, stop the vehicle and switch
off the engine as soon as possible.

Tyres:
check the tyre pressures of
the towing vehicle and of the trailer,
observing the recommended pressure.
Side wind:
sensitivity to side wind is
increased. Drive smoothly and at a
moderate speed.






Towbar

We recommend the use of original
CITROËN towbars, which have been
tested for endurance from the design
stage of your vehicle.
Towing equipment must be fi tted in
accordance with the manufacturer's
instructions, with particular attention to
the towing capacities of your vehicle,
the load towed, the nose weight and
the electrical connection. As this fi tting
should be carried out by a professional,
we recommend that you entrust the
fi tting of this equipment to a CITROËN
dealer.
In accordance with the general
instructions referred to above, we draw
your attention to the risk connected
with fi tting a towbar or other electrical
accessory which is not recommended
by the CITROËN network. Fitting such
equipment could result in a failure
of your vehicle's electronic system.
Please contact a CITROËN dealer fi rst
for further information.
Manual adjustment
Adjust your headlamps so as not to
dazzle other road users. Check the
electrical signalling of the trailer.
If you fi t a bicycle carrier on
the tailgate, deactivate the
rear wiper from the display's
confi guration menu.

Levels


Cooling system

Only use the fl uid 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.
Slacken the cap by 1/4 of a turn 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 fl uid has to be added frequently,
this indicates a failure which must be
checked by a CITROËN dealer as
soon as possible.

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. During regeneration of the particle
emission fi lter, relay noise may be
heard under the fascia.
If the message is still displayed and
the service warning light remains on,
contact a CITROËN dealer.

Diesel additive level (Diesel with
particle emission filter)
When this occurs with the engine running,
this is due to the start of saturation of
the particle emission fi lter (exceptionally
prolonged urban driving conditions: low
speed, long traffi c jams, ...).
In order to regenerate the fi lter, you are
advised to drive at a speed of more than
40 mph (60 km/h) as soon as possible,
when traffi c conditions permit, for at
least fi ve minutes (until the message
disappears and the service warning light
is switched off).
Topping up
The level must be between the MIN
and MAX marks on the expansion
bottle. If more than 1 litre of fl uid is
required to top up the level, have the
system checked by a CITROËN dealer.



Windscreen wash and headlamp
wash level
For best quality cleaning and for your
safety, we would advise that you use
products of the CITROËN range.
To avoid ice forming, do not use water.
Topping up
It is imperative that this additive is
topped up by a CITROËN dealer
without delay.



Used oil

Avoid prolonged contact of used oil
with the skin.
Brake fl uid is harmful to health and
very corrosive.
Do not dispose of used oil, brake
fl uid or coolant into drains or onto
the ground but into the containers
dedicated to this use at CITROËN
dealerships. The minimum level of this
additive is indicated by
lighting of the service warning
light, accompanied by an
audible signal and a message
on the display.

USES FUS

The designations communicated
only relate to the fuses which can
be changed by the user using the
tweezer and spare fuses, located in
the glove box behind the instrument
panel fuse box, on the right-hand side.
For any other work, visit a CITROËN
dealer.

Carefully close the cover when you
have fi nished.

The electrical system of your vehicle is
designed to operate with standard or
optional equipment.
Before installing other electrical
equipment or accessories on your
vehicle, consult a CITROËN dealer.


CITROËN will not accept responsibility
for the cost incurred in repairing
your vehicle or for rectifying the
malfunctions resulting from the
installation of accessories not supplied
and not recommended by CITROËN
and not installed in accordance with
its instructions, in particular where the
equipment in question consumes more
than 10 milliamperes. Intended for professionals: for full
fuse and relay information, consult the
"Workshop procedures" diagram via
the CITROËN network.
