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.

Petrol weights and towed loads (kg)
The values for approved towed weights vary
according to the sales zone (see the tables on
the following pages).
The exact values are given in your vehicle's
registration document as well as on the
manufacturer's plate.
They are also mentioned in sales brochures.
For more details, contact a CITROËN dealer or
a qualified workshop.The kerb weight is equal to the unladen
weight
+ driver (75 kg).The GTW and towed load values indicated are
valid up to a maximum altitude of 1 000 metres;
the towed load mentioned must be reduced
by 10 % for each additional 1 000 metres of
altitude.
The speed of a towing vehicle must not exceed
62 mph (100 km/h) (comply with the legislation
in force in your country).
High exterior temperatures may result in a
reduction in the per formance of the vehicle to
protect the engine; if the exterior temperature is
above 37 °C, limit the towed load.
The weight of the braked trailer can be
increased, within the GTW limit, if the
GV W of the towing vehicle is reduced
by an equal amount. Please note that
towing using a lightly loaded towing
vehicle may have an adverse effect
on its road holding
.
