Under-inflation detection
The system monitors the pressures in the four
tyres, once the vehicle is moving.
It compares the information given by the four
wheel speed sensors with reference values,
which must be reinitialised ever y time the
tyre pressures are adjusted or a wheel
changed.
The system triggers an alert as soon as it
detects a drop in the inflation pressure of one
or more tyres. The under-inflation detection system
does not replace the need for vigilance
on the part of the driver.
This system does not avoid the need to
check the tyre pressures (including the
spare wheel) every month as well as
before a long journey.
Driving with under-inflated tyres impairs
road holding, extends braking distances
and causes premature tyre wear,
particularly under arduous conditions
(high loading, high speed, long journey).
System which automatically checks the pressures of the tyres while driving.
The inflation pressures defined for
your vehicle can be found on the tyre
pressure label.
For more information on the
Identification markings, refer to the
corresponding section.
Tyre pressures should be checked
when the tyres are "cold" (vehicle
stopped for 1 hour or after a journey of
less than 6 miles (10 km) at moderate
speeds).
Other wise (when hot), add 0.3 bar to
the pressures shown on the label.
Driving with under-inflated tyres
increases fuel consumption.
Snow chains
The system does not have to be
reinitialised after fitting or removing
snow chains.
Spare wheel
The steel spare wheel does not have an
under-inflation detection sensor.

Towing a trailer
We recommend the use of genuine
CITROËN towbars and their harnesses
that have been tested and approved
from the design stage of your vehicle,
and that the fitting of the towbar is
entrusted to a CITROËN dealer or a
qualified workshop.
If the towbar is not fitted by a
CITROËN dealer, it must still be
fitted in accordance with the vehicle
manufacturer's instructions.
Your vehicle is primarily designed for
transporting people and luggage, but it may
also be used for towing a trailer. Driving with a trailer places greater
demands on the towing vehicle and the
driver must take particular care.
For more information on Driving

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.
Coolant level
The coolant level should be close
to the "MA X" mark but should never
exceed it.
In addition, as the cooling system is pressurised,
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. The cooling fan may star t after switching
off the engine: take care with ar ticles and
clothing that might be caught by the fan
blades. When the engine is warm, the temperature of
the coolant is regulated by the fan.
Check the coolant level regularly, according
to the use made of your vehicle (every
3 000
miles or 5 000 kms / 3 months); if
necessary, top-up using coolant recommended
by the manufacturer.
Topping-up the coolant between services is
normal.

Checks
12 V battery
The battery does not require any maintenance.
However, check regularly that the terminals
are correctly tightened (versions without quick
release terminals) and that the connections
are clean.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 filterParticle 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
multifunction screen.
As soon as the traffic conditions permit,
regenerate the filter by driving at a
speed of at least 40 mph (60 km/h) until
the warning lamp goes off.
If the warning lamp stays on, this
indicates a low additive level.
For more information on Checking
levels , 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.
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.
For more information and the precautions to
take before starting work on the 12 V batter y
,
refer to the corresponding section. 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.
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

AdBlue® and SCR system
for BlueHDi Diesel engines
To assure respect for the environment and
conformity with the new Euro 6 emissions
standard, without adversely affecting the
per formance or fuel consumption of Diesel
engines, CITROËN has taken the decision to
equip its vehicles with an effective system that
associates SCR (Selective Catalytic Reduction)
with a particle filter (FAP) for the treatment of
exhaust gases.
Presentation of the SCR system
Using a fluid called AdBlue® containing urea, a
catalytic converter turns up to 85% of nitrogen
oxides (NOx) into nitrogen and water, which are
harmless to health and the environment. The AdBlue
® is held in a special tank with
a capacity of about 22 litres: this provides
a driving range of about 12 500 miles
(20
000
km), after which an alert is triggered
warning you when the reserve remaining is
enough for just 1 500 miles (2 400 km).
During each scheduled service of your vehicle
by a CITROËN dealer or a qualified workshop,
the AdBlue
® tank is refilled in order to allow
normal operation of the SCR system. Once the AdBlue
® tank is empty, a
s
ystem required by regulations prevents
starting of the engine.
If the SCR
is faulty, the level of
emissions from your vehicle will no
longer meet the Euro 6 standard: your
vehicle becomes polluting.
In the event of a confirmed fault
with the SCR system, you must go
to a CITROËN dealer or a qualified
workshop as soon as possible: after
a running distance of 650 miles
(1
100 km), a system will be triggered
automatically to prevent engine starting.
When filling the tank, the filling rate
must not exceed 40 litres per minute.
If the estimated mileage between two services
is greater than 12 500 miles (20 000 km), we
recommend that you go to a CITROËN dealer
or a qualified workshop to have the necessary
top-up carried out.
