Advice on driving when towing
Distribution of loads
F Distribute the load in the trailer so that the heaviest items are as close as possible to
the axle and the nose weight approaches
the maximum permitted without
exceeding
it.
Air density decreases with altitude,
thus
reducing engine per formance. Above
1
000 metres, the maximum towing load must
be reduced by 10
% of the GTW and so on for
every 1
000 metres of altitude.
For more information on Petrol weights or
Diesel weights and in particular the towed
loads which apply to your vehicle, refer to the
corresponding section.
Side wind
F Take into account the increased sensitivity to side wind.
Cooling
Towing a trailer on a slope increases the
temperature of the coolant.
As the fan is electrically controlled, its cooling
capacity is not dependent on the engine speed.
F

T
o lower the engine speed, reduce your
speed.
The maximum towed load on a long slope
depends on the gradient and the exterior
temperature.
In all cases, pay attention to the coolant
temperature.
F

I
f this message is displayed, stop your
vehicle as soon as it is safe to do so.
Braking
Towing a trailer increases the braking distance.
To limit heat build-up in the brakes, use of the
engine brake is recommended.
Ty r e s
F Check the tyre pressures of the towing vehicle and of the trailer, observing the
recommended pressures.
Lighting
F Check the lighting and signalling on the trailer and the adjustment of the vehicle's
headlamps.
For more information on Headlamp
adjustment , refer to the corresponding
section.
If the message flashes slowly, wait for the
engine to cool before topping up the level, if
necessary.
If the message flashes rapidly, contact a
CITROËN dealer or a qualified workshop
without delay.
The rear parking sensors will be
deactivated automatically when a
genuine CITROËN towbar is used.

Brake wear depends on the style
of driving, particularly in the case
of vehicles used in town, over short
distances. It may be necessary to have
the condition of the brakes checked,
even between vehicle services.
Brake pads
For information on checking brake
disc wear, contact a CITROËN dealer
or a qualified workshop.
Brake disc wearParking brake
If excessive travel or a loss of
effectiveness of this system is
noticed, the parking brake must be
checked, even between two services.
Only use products recommended by
CITROËN or products of equivalent
quality and specification.
In order to optimise the operation of
units as important as those in the
braking system, CITROËN selects and
offers very specific products.
After washing the vehicle, dampness,
or in wintry conditions, ice can form
on the brake discs and pads: braking
efficiency may be reduced. Make light
brake applications to dry and defrost
the brakes.
Checking this system must be done by a
CITROËN dealer or a qualified workshop.
Unless there is a leak in the circuit, a drop in
the brake fluid level indicates that the brake
pads are worn.
Practical information

F If the specified pressure has not been reached after about 10 minutes, this means
that the tyre is not repairable; contact a
CITROËN dealer or a qualified workshop
for roadside assistance.
F

R
emove the compressor and stow the kit.Do not operate the compressor for more
than 10 minutes continuously.
If the compressor seems extremely
hot, switch it off and disconnect it
immediately. Leave it to cool for at
least
30 minutes. As soon as possible after a repair using
the kit, go to a CITROËN dealer or a
qualified workshop.
Make sure that you tell the technician
that you have used the kit. After
checking, the technician will advise you
whether the tyre can be repaired or if it
must be replaced.
If the vehicle is fitted with under-
inflation detection, the under-inflation
warning lamp remains on until the
system has been reinitialised.
For more information on Under-
inflation detection
, refer to the
corresponding section. F

rive off straight away at reduced speed
(50 mph (80 km/h) max) to spread the
sealant product within the tyre. F

A
fter about 6 miles (10 km) or 5 minutes,
stop and check the repair and the tyre
pressure using the compressor. If the
pressure has dropped slightly, inflate the
tyre again to the specified figure. Carry out
the same check after another 6 miles
(10 km) or 5 minutes: if the pressure
has not held at the specified figure, this
indicates that the puncture repair has not
sealed; contact a CITROËN dealer or a
qualified workshop for roadside assistance.
If the pressure is correct, carefully tighten the
tyre valve cap. You can drive at reduced speed
(50 mph (80 km/h) max) to go to a CITROËN
dealer or a qualified workshop.

Changing a bulb
For bulbs that have alignment lugs
(H1, H7...) ensure that they are
fitted correctly for the best lighting
performance.
The headlamps have polycarbonate
lenses with a protective coating:
F

d

o not clean them using a dr y
or abrasive cloth, nor with a
detergent or solvent product,
F

u

se a sponge and soapy water,
F

w

hen using a high pressure washer
on persistent marks, do not keep
the lance directed towards the
lamps or their edges for too long,
so as not to damage their protective
coating and seals.
F

D

o not touch the bulb directly with
your fingers, use lint-free cloths.
Changing a bulb should only be done
after the headlamp has been switched
off for several minutes (risk of serious
burns).
It is imperative to use only
anti-ultraviolet (UV) type bulbs in order
not to damage the headlamp.
Always replace a failed bulb with a
new bulb with the same type and
specification.
Risk of electrocution
Replacement of the xenon bulbs
(D1S-35W) must be carried out by
a CITROËN dealer or a qualified
workshop.
