Towing a trailer
ACCESSORIES

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.

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.
I f fl u i d h a s t o b e a d d e d f r e q u e n t l y ,
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

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

40 mph (60 km/h) as soon as possible,

Topping up
The level must be between the MIN
and MAX marks on the expansion

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.
B r a k e fl u i d i s h a r m f u l t o h e a l t h a n d

Do not dispose of used oil, brake
fl u i d o r c o o l a n t i n t o d r a i n s o r o n t o
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.
