If you find that the level is above the mark A or
below the mark B , do not star t the engine.

f the level is below the MIN mark, you must
top up the engine oil.
Oil grade
Before topping up the oil or changing the oil,
check that the oil is the correct grade for your
engine and conforms to the manufacturer's
recommendations.
Topping up the engine oil level
F Unscrew the oil filler cap to access the filler opening.

fter checking the level, carefully refit the oil
filler cap and the dipstick in its tube.
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.
Engine oil change
Refer to the manufacturer's service schedule
for details of the inter val for this operation.
In order to maintain the reliability of the engine
and emissions control system, never use
additives in the engine oil.
Brake fluid level
The brake fluid level should be close
to the "MA X" mark. If it is not, check
the brake pad wear.
Changing the fluid
Refer to the manufacturer's service schedule
for details of the inter val for this operation.
Fluid specification
This fluid must conform to the manufacturer's
recommendations.
Coolant level
Check the coolant level regularly.
It is normal to top up the fluid
between two services.
To ensure that the reading is correct, your
vehicle must be parked on a level sur face with
the engine cool.
The coolant level should be close to the "MA X"
mark but should never exceed it.
If the level is close to or below the "MIN" mark,
it is essential to top up.
The location of the oil filler cap is shown in the
corresponding underbonnet layout view.

For more information on the precautions
to take before starting work on the 12 V
battery , refer to the corresponding
section.
Versions equipped with Stop & Start are
fitted with a 12
V lead-acid battery of
specific technology and specification.
Its replacement should be carried out
only by a CITROËN dealer or a qualified
workshop.
Air filter
Depending on the environment
(e.g. dusty atmosphere) and the
use of the vehicle (e.g. city driving),
replace it twice as often if
necessary .
Passenger compartment filter
Depending on the environment
(e.g. dusty atmosphere) and the
use of the vehicle (e.g. city driving),
replace it 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.
Oil filter
Replace the oil filter each time the
engine oil is changed.
Particle filter (Diesel)
The start of saturation of the particle
filter is indicated by the constant
illumination of this warning lamp
accompanied by an alert message.
As soon as the traffic conditions permit,
regenerate the filter by driving at a speed
of at least 37
mph (60 km/h) until the
warning lamp goes off.
If the warning lamp stays on, this indicates
a low Diesel additive level.
For more information on Checking levels
and particularly on the level of Diesel
additive, 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.
Manual gearbox
The gearbox does not require any
maintenance (no oil change).

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.
