Automatic gearbox
The gearbox does not require any
maintenance (no oil change).
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.
Unless there is a leak in the circuit, a drop in
the brake fluid level indicates that the brake
pads are worn.
Brake disc wear
For information on checking brake
disc wear, contact a CITROËN or a
qualified workshop.
Parking brake
If excessive travel or a loss of
effectiveness of this system is
noticed, the parking brake must
be checked, even between two
services.
Checking this system must be done 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
components 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.
AdBlue® (BlueHDi
engines)
SCR system
Using a liquid called AdBlue® that contains
urea, a catalytic converter turns up to 85% of
the oxides of nitrogen (NOx) into nitrogen and
water, which are harmless to health and the
environment.
The AdBlue
® is contained in
a special tank holding about
15


litres.
An alert system is triggered automatically once
the reser ve level is reached: you can then drive
for a further 1,500

miles (2,400 km) before the
tank is emptied completely.

Parking the vehicle
Stop the vehicle where it does not block
traffic: the ground must be level, stable
and non-slippery.
Apply the parking brake, switch off the
ignition and engage first gear* so as to
block the wheels.
Check that the parking brake warning
lamp comes on fixed in the instrument
panel.
The occupants must get out of the vehicle
and wait in a safe place.
Make sure that the jack is correctly
positioned at one of the vehicle's jacking
points.
Incorrect use of the jack could cause the
vehicle to collapse.
Never go underneath a vehicle raised
using a jack; use an axle stand.

Fitting a wheelAfter changing a wheel
Do not exceed 50
mph (80 km/h) when
driving with the "space-saver" type spare
wheel fitted.
Visit a CITROËN dealer or a qualified
workshop as soon as possible to have the
tightness of the bolts and the pressure of
the spare wheel checked.
Have the punctured wheel checked. After
inspection, the technician will let you know
if the tyre can be repaired or if it must be
replaced.
List of operations
Fitting the " space-saver " spare wheel
If your vehicle is fitted with alloy wheels,
when tightening the bolts on fitting it is
normal to notice that the washers do not
come into contact with the "space-saver"
spare wheel. The wheel is secured by the
conical contact of each bolt. F

P

Changing a bulb
The headlamps have polycarbonate
lenses with a protective coating:
F
d
o not clean them using a dr y or
abrasive cloth, nor with a detergent
or solvent product,
F

u
se a sponge and soapy water or a pH
neutral product,
F

w
hen using a high pressure 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

D
o not touch the bulb directly with your
fingers, use a lint-free cloth.
It is essential only to use anti-ultraviolet
(UV) type bulbs, so as not to damage the
headlamp.
Always replace a failed bulb with a new
bulb with the same type and specification. Light emitting diodes (LED)
For the replacement of this type of bulb,
you must contact a CITROËN dealer or a
qualified workshop.
In some weather conditions (e.g. low
temperature or humidity), the presence
of misting on the internal sur face of the
glass of the headlamps and rear lamps is
normal; it disappears after the lamps have
been on for a few minutes.
