Checking levels
Check all of the following levels regularly in
accordance with the manufacturer's service
schedule. Top them up if required, unless
otherwise indicated.
If a level drops significantly, have the
corresponding system checked by a CITROËN
dealer or a qualified workshop.
The fluids must comply with the manufacturer's requirements and with
the vehicle's engine.
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).
Used products
Avoid prolonged contact of used oil or fluids with the skin.
Most of these fluids are harmful to health and
very corrosive.
Do not discard used oil or fluids into
sewers or onto the ground.
Empty used oil into the containers reserved
for this purpose at a CITROËN dealer or a
qualified workshop.
Engine oil
The level is checked, with the engine having been switched off for at least 30
minutes and on level ground, either using the oil
level indicator in the instrument panel when the
ignition is switched on (for vehicles equipped
with an electric gauge), or using the dipstick.
It is normal to top up the oil level between two
services (or oil changes). It is recommended
that you check the level, and top up if necessary,
every 3,000 miles (5,000 km).
In order to maintain the reliability of the
engine and emissions control system,
never use additives in the engine oil.
Checking using the dipstick
For the location of the dipstick, please refer
to the illustration of the corresponding engine
compartment.
►

Grasp the dipstick by its coloured grip and
pull it out completely

.
►

Wipe the end of the dipstick using a clean,
lint-free cloth.


► Reinsert the dipstick and push fully down,
then pull it out again to visually check the oil
level: the correct level is between marks A
(max)
and B (min).
Do not start the engine if the level is:
–

above mark
A: contact a CITROËN dealer or a
qualified workshop.
–

below mark B

: top up the engine oil
immediately.

Practical information
7Oil grade
Before topping up or changing the
engine oil, check that the oil is suitable
for your engine and complies with the
recommendations in the service schedule
supplied with the vehicle (or available from
your CITROËN dealer or qualified workshop).
Use of non-recommended oil may invalidate
your warranty in the event of engine failure.
Topping up the engine oil level
For the location of the engine oil filler cap, please
refer to the corresponding engine compartment
illustration.
►

Add oil in small quantities, avoiding any spills
on engine components (risk of fire).
►


W
ait a few minutes before checking the level
again using the dipstick.
►

T
op up the level if necessary.
►

After checking the level, carefully screw the
oil filler cap back on

and replace the dipstick in
its tube.
The oil level indication displayed on the instrument panel when the ignition is
switched on is not valid for 30 minutes
following an addition of oil.
Brake fluid
The level of this fluid should be close to
the "MAX" mark. If not, check the brake
pads for wear.
To know how often the brake fluid should be
replaced, refer to the manufacturer's servicing
schedule.
Clean the cap before removing it to refill.
Use only DOT4 brake fluid from a sealed
container.
Engine coolant
(Petrol or Diesel)
It is normal to top up this fluid between
two services.
The check and top-up must only be done with
the engine cold.
A level of coolant that is too low risks causing
major damage to the engine; the coolant level
must be close to the "MAX" mark without ever
going above it.
If the level is close to or below the " MIN" mark, it
is essential to top it up.
When the engine is hot, the temperature of the
coolant is regulated by the fan.
As the cooling system is pressurised, wait at
least one hour after switching off the engine
before carrying out any work.
In order to avoid the risk of scalding if you need
to top up in an emergency, wrap a cloth around
the cap and unscrew the cap by two turns to
allow the pressure to drop.
Once the pressure has dropped, remove the cap
and top up to the required level.
(Electric)
Do not top up the coolant.
If the level is close to or below
the "MIN" mark, it is essential to contact a
CITROËN dealer or a qualified workshop.
Screenwash fluid
Top up to the required level when necessary.
Fluid specification
The fluid must be topped up with a pre-mixed
product.
In winter (temperatures below zero), a fluid
containing an anti-freeze agent which is
appropriate for the temperature conditions
must be used in order to protect the system's
components (pump, tank, ducts, jets).
Filling with pure water is prohibited in all
circumstances (risk of freezing,
limescale, etc.).

Practical information
AdBlue® (BlueHDi)
An alert is triggered when the reserve level is
reached.
For more information on the Indicators and in
particular the AdBlue range indicators, refer to
the corresponding section.
To avoid the vehicle being immobilised in
accordance with regulations, you must top up the
AdBlue tank.
For more information on AdBlue
® (BlueHDi),
and in particular the supply of AdBlue, refer to
the corresponding section.
Checks
Unless otherwise indicated, check these
components in accordance with the
manufacturer's service schedule and according
to your engine.
Otherwise, have them 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
components as important as those in the
braking system, CITROËN selects and offers
very specific products.
12 V battery
The battery does not require any maintenance.
Check regularly that the terminals are correctly
tightened (versions without quick-release
terminals) and that the connections are clean.
For more information on the precautions
to take before any 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.
Passenger compartment
filter
Depending on the environment and the
use of the vehicle (e.g. dusty atmosphere,
city driving), change it twice as often, if
necessary .
A clogged passenger compartment filter
can adversely affect air conditioning
system performance and generate
undesirable odours.
Air filter
Depending on the environment and the
use of the vehicle (e.g. dusty atmosphere,
city driving), change it twice as often, if
necessary .
Oil filter
Change the oil filter each time the engine
oil is changed.
Particle filter (Diesel)
The start of clogging of the particle filter is
indicated by the temporary lighting 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.
Following prolonged operation of the
vehicle at very low speed or at idle, you
may, in exceptional circumstances, notice
water vapour coming from the exhaust while
accelerating. These emissions have no
impact on the vehicle’s behaviour and the
environment.
New vehicle
During the first few particle filter
regeneration operations, you may notice a
"burning" smell. This is perfectly normal.

7Manual gearbox
The gearbox does not require any maintenance (no oil change).
Automatic gearbox
The gearbox does not require any maintenance (no oil change).
Manual parking brake
If you notice excessive brake lever travel
or decreased effectiveness, the parking
brake must be adjusted, even between two
services.
This system must be checked by a CITROËN
dealer or a qualified workshop.
Electric parking brake
This system does not require any routine servicing. However, in the event of a
problem, do not hesitate to have the system
checked by a CITROËN dealer or a qualified
workshop.
For more information on the Electric
parking brake, refer to the
corresponding section.
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.
After washing the vehicle, moisture, or in wintry conditions, ice can form on the
brake discs and pads: braking efficiency may
be reduced. Gently dab the brakes to dry and
defrost them.
Brake disc/drum wear
For any information on checking brake
disc/drum wear, contact a CITROËN
dealer or a qualified workshop.
Wheels and tyres
The inflation pressure of all tyres, including the spare wheel, must be
checked on "cold” tyres.
The pressures indicated on the tyre pressure
label are valid for "cold" tyres. If you have driven
for more than 10 minutes or more than 6 miles
(10 kilometres) at over 31 mph (50
km/h), add
0.3 bar (30 kPa) to the values indicated on the
label.
Under-inflation increases energy
consumption. Non-compliant tyre
pressures cause tyres to wear prematurely
and have an adverse effect on the vehicle's
road holding - risk of accident! Driving with worn or damaged tyres reduces the
braking and road holding performance of the
vehicle. Regularly check the condition of the
tyres (tread and sidewalls) and rims as well as
the presence of the valve caps.
When the wear indicators no longer appear set
back from the tread, the depth of the grooves is
less than 1.6 mm; replace the tyres as soon as
possible.
Using different size wheels and tyres from those
specified can affect the lifetime of tyres, wheel
rotation, ground clearance, the speedometer
reading and have an adverse effect on road
holding.
Fitting different tyres on the front and rear axles
can cause the ESC to mistime.
Always mark the direction of rotation on the tyres
that will be stored when fitting winter or summer
tyres. Store them in a cool, dry place and away
from direct exposure to the sun's rays.
Winter or 4-seasons tyres can be
identified by this symbol on their
sidewalls.
Shock absorbers
It is not easy for drivers to detect when
shock absorbers are worn. Nevertheless,
the shock absorbers have a major impact on
road holding and braking performance.
For your safety and driving comfort, it is
important to have them regularly checked by a
CITROËN dealer or a qualified workshop.

160
Practical information
Timing and accessory kits
The timing and accessory kits are used
from the time the engine is started until it
is switched off. It is normal for them to wear over
time.
A
faulty timing or accessory kit can damage
the engine, rendering it unusable. Observe the
recommended replacement frequency, stated in
distance travelled or time elapsed, whichever is
reached first.
AdBlue® (BlueHDi)
To respect the environment and ensure compliance with the Euro 6 standard, without
adversely affecting the performance or fuel
consumption of its Diesel engines, CITROËN
has taken the decision to equip its vehicles with
a system that combines SCR (Selective Catalytic
Reduction) with a Diesel Particle Filter (DPF) for
the treatment of exhaust gases.
SCR system
Using a liquid called AdBlue® that contains
urea, a catalytic converter turns up to 85% of
the nitrogen oxides (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.
Its capacity allows a driving range of
approximately 4,000
miles (6,500 km),
which
may vary considerably depending on your
driving style.
An alert system is triggered once the reserve
level is reached: it is then possible to drive for a
further 1,500 miles (2,400
km) before the tank is
empty and the vehicle is immobilised.
For more information on the Warning
and indicator lamps and the associated
alerts, or the Indicators, please refer to the
corresponding sections.
Once the AdBlue® tank is empty, a device
required by law prevents the engine from
being restarted.
If the SCR system is faulty, the level of
emissions from the vehicle will no longer meet
the Euro 6 standard and the vehicle starts
polluting the environment.
In the event of a confirmed SCR system
malfunction, it is essential to visit a CITROËN
dealer or a qualified workshop. After 685
miles (1,100 km), a device is automatically
activated to prevent the engine from starting.
In both cases, a range indicator indicates
the distance that can be travelled before the
vehicle is stopped.
Freezing of the AdBlue®
AdBlue® freezes at temperatures below
around -11°C.
The SCR system includes a heater for the
AdBlue® tank, allowing you to continue driving
in very cold conditions.
Supply of AdBlue®
It is recommended that the AdBlue® be topped
up as soon as the first alert is issued indicating
that the reserve level has been reached.
For the correct operation of the SCR
system:
–

Use
only AdBlue
® fluid that meets the ISO
22241 standard.
–

Never

transfer AdBlue
® to another container
as it would lose its purity.
–

Never

dilute AdBlue
® with water.
You can obtain AdBlue
® from a CITROËN dealer
or a qualified workshop, as well as service
stations equipped with AdBlue
® pumps specially
designed for passenger vehicles.
Recommendations on storage
AdBlue® freezes at about -11°C and deteriorates
above +25°C. Containers should be stored in a
cool area and protected from direct sunlight.
Under these conditions, the fluid can be kept for
at least a year.
If the fluid has frozen, it can be used once it has
completely thawed out at room temperature.
Never store AdBlue® containers in your
vehicle.
