Electric parking brake
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.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.
Brake disc wear
For information on checking brake
disc wear, contact a CITROËN dealer
or a qualified workshop.
Manual parking brake
If a loss of effectiveness of this
system is noticed, the parking brake
must be checked, even between
two
services.
Brake pads
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.
For more information, refer to the "Electric
parking brake - Operating faults" section.
Unless there is a leak in the circuit, a drop in
the brake fluid level indicates that the brake
pads are worn.
Checking this system must be done by a
CITROËN dealer or a qualified workshop.
Checks

Never store bottles of AdBlue® in your
vehicle.
Recommendations on storage
AdBlue® freezes at about -11°C and
deteriorates above 25°C. It is recommended
that bottles be stored in a cool area and
protected from direct sunlight.
Under these conditions, the additive can be
kept for at least a year.
If the additive has frozen, it can be used once it
has completely thawed out. Before topping-up, ensure that the vehicle is
parked on a flat and level sur face.
In wintry conditions, ensure that the
temperature of the vehicle is above -11°C.
Other wise, by freezing, the AdBlue
® cannot
be poured into its tank. Park your vehicle in a
warmer area for a few hours to allow the top-up
to be carried out.
Procedure
F Switch off the ignition and remove the key, or if your vehicle has one, press the
START/STOP button to switch off the
engine. F

R
aise the boot floor for access to the
AdBlue
® tank. S
ecure the boot floor by attaching its cord

pH neutral product,
F

w

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. Changing a bulb should only be done
after the headlamp has been switched
off for several minutes (risk of serious
burns).
F

your fingers, use a lint-free cloth.
It is imperative to use only anti-
