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 wear
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.
Electric parking brake
For more information, refer to the "Electric
parking brake - Operating faults " section.
This system does not require any
routine servicing. However, in the
event of a problem, have the system
checked by a CITROËN dealer or a
qualified workshop.
Manual gearbox
The gearbox does not require any
maintenance (no oil change).
Refer to the manufacturer's service
schedule for the checking interval for
this component.
Automatic gearbox
The gearbox does not require any
maintenance (no oil change).
Refer to the manufacturer's service
schedule for details of the level
checking interval for this component.
To avoid damaging the electrical units,
never use a high pressure jet wash in
the engine compartment.
Unless there is a leak in the circuit, a drop in
the brake fluid level indicates that the brake
pads are worn.
