Brake pads Brake wear depends on
the style of driving, par-
ticularly in the case of ve-
hicles used in town, over
short distances. It may be
necessary to have the condition of
the brakes checked, even between
vehicle services.
Unless there is a leak in the circuit, a
d r o p i n t h e b r a k e fl u i d l e v e l i n d i c a t e s
that the brake pads are worn.
Manual gearbox
The gearbox does not re-
quire any maintenance (no
oil change).
Automatic gearbox The gearbox does not re-
quire any maintenance
(no oil change). Brake disc wear status
For information relating to
checking the brake disc
wear status, contact a
CITROËN dealer.

too long or if a loss of ef-
fectiveness of this system
is noticed, the handbrake
must be adjusted, even
between two services.

CITROËN dealer. Only use products recom-
mended by CITROËN or
products of equivalent qual-
i t y a n d s p e c i fi c a t i o n s .
