Coolant level
The coolant level should be between
the two marks.In addition, as the cooling system is
pressurised, wait at least one hour after
switching off the engine before carrying out any
work.
To avoid any risk of scalding, unscrew the cap
by two turns to allow the pressure to drop.
When the pressure has dropped, remove the
cap and top up the level.
Fluid specification
The coolant must conform to the
manufacturer's recommendations.
The brake fluid level should be close
to the "MA X" mark. If it is not, check
the brake pad wear.
Brake fluid level
Changing the fluid
Refer to the maintenance and warranty guide
for details of the interval for this operation.
Fluid specification
The brake fluid must conform to the
manufacturer's recommendations and meet
the
DOT3 or DOT4 standard.
The cooling fan may star t after switching
off the engine: take care with ar ticles and
clothing that might become caught by the
fan blades. When the engine is warm, the temperature of
the coolant is regulated by the fan.
Checks

fluids with the skin.
Most of these fluids are harmful to
health or indeed very corrosive.
Do not discard used oil or fluids into
sewers or onto the ground.
Take used oil to a CITROËN dealer or
a qualified workshop (France) or to an
authorised waste disposal site.

Checks

218
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 maximum towed weights type
approved 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
60 mph (100 km/h) (comply with the legislation
in force in your country).
High ambient temperatures may result in a
reduction in the per formance of the vehicle to
protect the engine; if the ambient 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
