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 9.
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.

186
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. Please contact a CITROËN dealer fi rst
for further information
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 If you fi t a bicycle carrier on
the tailgate, deactivate the
rear wiper from the display's
confi guration menu.
Refer to the "Identifi cation
features" section of chapter 9. 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 8.

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. Manual adjustment
Adjust your headlamps so as not to
dazzle other road users. Check the
electrical signalling of the trailer.

VERY COLD CLIMATE SCREEN
If fi tted on your vehicle, this is a

or partial covering of the front air intake
(grille, ...) to favour the increase in the
engine temperature when driving in
very low temperatures and to prevent
the entry of snow into the engine
compartment. FITTING

the engine off .
- Open the fuel fi ller fl ap.
- Insert the key then turn it to the left.
- Remove the cap and attach it to
the clip located on the inside of the
fl ap.
FILLING THE FUEL TANK
When the fuel fi ller fl ap is open, a
system limits the opening of the
rear left sliding side door.
The key cannot be removed from the
cap's lock until the cap is refi tted on
the tank.

FUEL CIRCUIT DISARMED
In a serious collision, a mechanism
automatically prevents fuel from
reaching the engine.
The fl ashing of this warning
light is accompanied by a
message on the display.
When the tank's minimum
level is reached, this warning
light comes on, accompanied
by the message "Fuel
level low" on the display.
You have enough fuel left to cover
approximately 30 miles (50 km) ,
