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.

CHECKS
To check the main levels
and certain components,
in accordance with the
manufacturer's servicing schedule,
refer to the pages of the Maintenance
and Warranty Guide which correspond
to your vehicle's engine.
Only use products recommended
by CITROËN or products
of equivalent quality and
specifi cation.
In order to optimise the operation
of units as important as the braking
system, CITROËN selects and offers
specifi c products.
In order to avoid damaging the
electrical units, high pressure washing
to clean the engine compartment is
strictly prohibited.
Oil filter
Change the fi lter regularly, in
accordance with the servicing
schedule. Refer to the servicing booklet to
fi nd out the replacement interval
for these components.
Depending on the environment
(dusty atmosphere...) and the use of
the vehicle (urban driving...), change
them twice as often if necessary.
Refer to the "Under the bonnet" section
of chapter 6. Particle emission filter (Diesel)
It is imperative that particle emission
fi lter maintenance is carried out by a
CITROËN dealer.
On acceleration after the vehicle has
been running for a prolonged period
at very low speed or at idle, you may,
in exceptional circumstances, notice
the emission of water vapour at the
exhaust. This water vapour does not
have any adverse effect on vehicle
handling or the environment.
Battery
At the start of winter, have your battery
checked by a CITROËN dealer.
Brake pads
Brake pad wear depends on the style
of driving, in particular for vehicles
which are used in town, over short
distances. It may be necessary to
check the thickness of the pads, even
between services.
Unless there is a leak on the circuit, a
drop in the brake fl uid level indicates
that the brake pads are worn.
Brake disc/drum wear status
For any information relating to
checking the brake disc/drum wear
status, contact a CITROËN dealer.
Handbrake
Where the handbrake travel is too
great or there is a reduction in the
performance of the system, the
handbrake should be adjusted, even
between services.
Have the system checked by a
CITROËN dealer. Carbon filter and passenger
compartment filter
The carbon fi lter permits continuous
and effective fi ltering of dust.
If the passenger compartment fi lter
becomes clogged, this may reduce
the performance of the air conditioning
system and generate unpleasant
odours.
We recommend the use of a combined
passenger compartment fi lter. By
means of its second special active
fi lter, it contributes to the purifi cation
of the air breathed by the occupants
and to the cleanness of the passenger
compartment (reduction of allergic
symptoms, unpleasant odours and
greasy deposits).
Manual gearbox
Have the level checked in accordance with
the manufacturer's servicing schedule.

Having your vehicle towed
From the rear
- unclip the top of the cover using a coin,
- screw in the removable towing eye until it locks.
TOWING YOUR VEHICLE
Special features of
the automatic gearbox
When being towed with four wheels on
the road, it is essential to observe the
following rules:
- selector lever in position N ,
- tow the vehicle at a speed below 30 mph (50 km/h) over a distance
limited to 30 miles (50 km) maximum,
- do not add oil to the gearbox.
When towing with the engine switched
off, there is no braking or steering
assistance.
Without lifting (4 wheels on the road)
You should always use a towbar.
The removable towing eye is inside
the engine compartment.
From the front
- unclip the cover by pressing the
bottom part,
- screw in the removable towing eye until it locks. Lifting (2 wheels on the road only)
It is preferable to raise the vehicle
using professional lifting equipment.
VEHICLES FITTED WITH A MANUAL
GEARBOX (diesel version)
In the case of vehicles fi tted with a
manual gearbox, the gear lever must
be in the neutral position. Failure to
observe this special condition may
result in damage to certain braking
components and the absence of
braking assistance the next time the
engine is started.
Put the gear lever in neutral.
Failure to observe this rule may
result in damage to certain
components.
