Fitting roof bars
The transverse roof bars are fitted to the longitudinal bars at the 8 fixing points masked by covers.
Using a small screwdriver, remove the 8 covers on the inner faces of the longitudinal bars.
The transverse bars are fitted directly to the roof of the vehicle, at the 4 anchorage points masked
by covers.
Slide the covers towards the front of the vehicle to remove them.
Retain the protective covers.
After removing the roof bars, the protective covers should be refitted:
F
i
nsert the fixing tongues into the apertures then slide the covers towards the rear of the vehicle. The body sill finishers should not be
used as a step when fitting roof bars.Use accessories recommended by
CITROËN and follow the accessory
manufacturer's fitting instructions.
Maximum authorised weight on the roof
bars, for a loading height not exceeding
40
cm (except bicycle carriers): 80 kg.
If the height exceeds 40 cm, adapt the
speed of the vehicle to the condition of
the road, to avoid damaging the roof
bars and the fixings on the roof.
Please refer to national legislation to
comply with the regulations regarding
the transportation of objects which are
longer than the vehicle.
For reasons of safety and to avoid damaging the roof, it is essential to use transverse bars that are
approved for your vehicle.

Checking levels
Take care when working under the bonnet, as certain areas of the engine may be extremely hot (risk of burns) and the cooling fan could start at
any time (even with the ignition off).
Oil level
The check of the level is done with
the dipstick, located under the
bonnet. Refer to the description of
your engine compartment for the
position of the dipstick.Engine oil change
Refer to the manufacturer's service schedule
for details of the interval for this operation.
In order to maintain the reliability of the engine
and emission control system, never use
additives in the engine oil.
Oil specification
The oil must be the correct grade for your
engine and conform to the manufacturer's
recommendations.
Check all of these levels regularly, in line with the manufacturer's service schedule. Top them up if necessary, unless other wise indicated.
If a level drops significantly, have the corresponding system checked by a CITROËN dealer or a qualified workshop.
Dipstick
There are two marks on the dipstick:
A = maximum
If the level is above this
mark, contact a CITROËN
dealer or a qualified
workshop.
B = minimum
Top up the level through the
oil filler orifice, using the
correct grade of oil for your
engine. The level must never
be below this mark.
This check will only be correct if the vehicle is
on level ground and the engine has been off for
more than 30 minutes.
It is normal to top up the oil level between
two services (or oil changes). CITROËN
recommends that you check the level, and top
up if necessary, every 3 000 miles (5 000 km).
After topping up the oil, the check when
switching on the ignition with the oil level
indicator in the instrument panel is not valid
during the 30 minutes after topping up.

Coolant level
The coolant level should be between
the two marks.When the engine is warm, the temperature of
the coolant is regulated by the fan.
As the cooling system is pressurised when the
engine is warm, 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 manufacturer's service schedule
for details of the interval for this operation.
Fluid specification
The brake fluid must conform to the
manufacturer's recommendations.
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. To ensure that this measurement is reliable, the
vehicle must be parked on level ground with the
engine cold.

Avoid prolonged contact of used oil or
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.

Checking components
12 V battery
Electrolyte level
For access to the 12 V Battery, refer
to the corresponding section. Refer to the manufacturer's
service schedule for details of the
replacement intervals for these
components.
Air filter and passenger compartment filter
Replace the oil filter each time the
engine oil is changed.
Refer to the manufacturer's
service schedule for details of
the replacement interval for this
component.
Oil filter
If necessary, top up using distilled water,
removing the battery cap from each cell.
Check the electrolyte level at least once a
month.
When carrying out work on the 12 V
Battery,
refer to the corresponding section for
details of the precautions to be taken before
disconnecting the battery and following its
reconnection.
Unless other wise indicated, check these components in accordance with the manufacturer's service schedule and according to your engine.
Other wise, have them checked by a CITROËN dealer or a qualified workshop.
The electrolyte level must be between the
"LOWER LEVEL" and "UPPER LEVEL" marks.
Depending on the environment (e.g. dusty
atmosphere) and the use of the vehicle
(e.g. city driving), replace them twice as often
if necessary
.
A clogged passenger compartment filter may
have an adverse effect on the per formance
of the air conditioning system and generate
undesirable odours.

Manual gearbox
For servicing of the gearbox, refer to
the manufacturer's service schedule
for details of the interval for checking
this component.
"CVT" gearbox
For servicing of the "CVT" gearbox,
refer to the manufacturer's service
schedule for details of the interval for
checking this component.
Particle filter (Diesel)
The start of saturation of the particle filter is
indicated by the temporary illumination of this
warning lamp, accompanied by a message in
the instrument panel screen.As soon as the traffic conditions permit,
regenerate the filter by driving at a
speed of at least 25 mph (40 km/h) for
about 20 minutes (with the 1.6 litre HDi
engine, the minimum speed is 37 mph
(60 km/h)).
If the warning lamp stays on, this
indicates a low additive level.
For more information on Checking
levels
and the Diesel additive level in
particular, refer to the corresponding
section.
On a new vehicle, the first particle
filter regeneration operations may be
accompanied by a "burning" smell,
which is per fectly normal.
Following prolonged operation of the
vehicle at very low speed or at idle,
you may, in exceptional circumstances,
notice the emission of water vapour at
the exhaust on acceleration. This does
not affect the behaviour of the vehicle
or the environment.

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.
