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.
Contact a CITROËN dealer .
COOLANT TEMPERATURE INDICATOR
In zone A , the temperature is correct.
In zone B , the temperature is too high.
The central STOP warning light and

"Engine coolant temp. too high" on
the display.

You must stop immediately.
Wait for the engine to cool before
topping up the level.
The cooling system is pressurised.

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

Towing a trailer
ACCESSORIES
5
TOWING A TRAILER, CARAVAN, BOAT, ETC...
Refer to the administrative
documents (V5, ...) or to the Petrol
or 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.

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.
