Limit the causes of excess
consumption
Spread loads throughout the vehicle; place
the heaviest items at the back of the boot, as
close as possible to the rear seats.
Limit the loads carried in the vehicle and
reduce wind resistance (roof bars, roof rack,
bicycle carrier, trailer, etc.). Preferably, use
a roof box.
Remove roof bars and roof racks after use.
At the end of winter, remove snow tyres and
refit your summer tyres.
Obser ve the recommendations on
maintenance
Check the tyre pressures regularly, when cold,
referring to the label in the door aperture,
driver's side.
Carry out this check in particular:
-

b
efore a long journey,
-

a
t each change of season,
-

a
fter a long period out of use.
Do not forget the spare wheel and the tyres on
any trailer or caravan.
Have your vehicle ser viced regularly (engine
oil, oil filter, air filter, cabin filter, etc.) and
obser ve the schedule of operations in the
manufacturer's service schedule. When filling the tank, do not continue after the
3
rd cut-off of the nozzle to avoid over flow.
At the wheel of your new vehicle, it is only
after the first 1,900
miles (3,000 kilometres)
that you will see the fuel consumption settle
down to a
consistent average.
With a
BlueHDi Diesel engine, if the SCR
system is faulty, your vehicle becomes
polluting. Visit a CITROËN dealer or
a

qualified workshop as soon as possible to
bring your vehicle's nitrogen oxides emissions
back in line with regulations.

Malfunction of the SCR
emissions control system
Malfunction detection
If a malfunction is detected,
t hese warning lamps come on,
accompanied by an audible signal
and the display of an "Emissions
fault" message.
The alert is triggered while driving as soon
as the fault is detected for the first time, then
when switching on the ignition for subsequent
journeys, while the fault persists. If it is a
temporary fault, the alert
disappears during the next journey,
after self-diagnostic checks of the SCR
emissions control system.
Malfunction confirmed during the
permitted driving phase (between
685
miles and 0 miles (1,100 km and 0 km))
If the warning lamp is still on after 31 miles
( 50 km) of driving, the fault in the SCR system
is confirmed. Have the system checked by a
CITROËN
dealer or a qualified workshop as soon as
possible.
Starting prevented
Every time the ignition is switched on, the
message "Emissions fault: Starting prevented"
is displayed.
To be able to restart the engine, call
on a
CITROËN dealer or a qualified
workshop.
The AdBlue warning lamp flashes,
accompanied by the display of a
message
("Emissions fault: Starting prevented in x
miles") indicating the remaining range in miles
or kilometres.
While driving, the message is displayed every
30

seconds. The alert is repeated when
switching on the ignition.
You can continue driving for up to 685 miles
(1,100 km) before the engine star ting
prevention system is triggered.

Emergency braking assistance
(EBA)
In an emergency, this system enables you to
reach the optimum braking pressure more
quickly and therefore reduce the stopping
distance.
It is triggered in relation to the speed at which
the brake pedal is pressed. This is felt by
a reduction in the resistance of the pedal and
an increase in braking efficiency.
Anti-slip regulation (ASR)
This system optimises traction in order to
avoid wheel slip by acting on the brakes of
the driving wheels and on the engine. It also
improves the directional stability of the vehicle
on acceleration.
Dynamic stability control (DSC)
If there is a difference between the path
f ollowed by the vehicle and that required by the
driver, this system monitors each wheel and
automatically acts on the brake of one or more
wheels and on the engine to return the vehicle
to the required path, within the limits of the laws
of physics.
Trailer stability assist (TSA)
This system allows control of the vehicle to be
retained when towing a trailer, so as to avoid
the risk of snaking.
Anti-lock braking system
(ABS) and electronic brake
force distribution (EBFD)
The fixed illumination of this warning
lamp signals that there is a fault with
the ABS.
Illumination of this warning lamp,
coupled with the STOP and ABS
warning lamps, accompanied by the
display of a
message and an audible
signal, signals that there is a
fault
with the electronic brake force
distribution (EBFD). Normal operation of the ABS may make
itself felt by slight vibrations of the brake
pedal.
When braking in an emergency, press
very firmly and maintain this pressure.
When changing wheels (tyres and rims),
ensure that these are approved for your
vehicle.
After an impact, have these systems
checked by a
CITROËN dealer or
a


qualified workshop.
Intelligent traction control
system ("Snow motion ")
The vehicle retains conventional braking. Drive
carefully at moderate speed.
Contact a
CITROËN dealer or a qualified
workshop as soon as possible.
You must stop as soon as it is safe to do so.
Call a
CITROËN dealer or a qualified
workshop. Depending on version, your vehicle has
a
system to help driving on snow: intelligent
traction control.
This system detects situations of poor sur face
grip that could make it difficult to move off
or make progress on deep fresh snow or
compacted snow.
In these situations, the intelligent traction
control limits the amount of wheel spin to
provide the best traction and trajectory control
for your vehicle.

The vehicle stalls in STOP mode
All of the instrument panel warning lamps come
on if this fault occurs.The Stop & Start system requires a
12 V
battery of specific technology and
specification.
All work concerning the battery must be
carried out only by a
CITROËN dealer or
a


qualified workshop.
After the engine has restarted, STOP
mode is not available until the vehicle has
reached a speed of 5 mph (8 km/h).
During parking manoeuvres, STOP mode
is not available for a few seconds after
coming out of reverse gear or turning the
steering wheel.
The engine automatically restarts as soon as
the driver indicates the intention of moving off
again.
Tyre under-inflation
detection
This system automatically checks the
pressures of the tyres while driving.
It compares the information given by the 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.
Under-inflation detection does not replace
the need for vigilance on the part of the
driver.
This system does not avoid the need
to regularly check the tyre pressures
(including the spare wheel) as well as
before a


long journey.

Identification markings , refer to the
corresponding section. Checking tyre pressures
This check should be done 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, add 0.3

If the warning lamp stays on, this indicates
a low Diesel additive level.
For more information on Checking levels ,
refer to the corresponding section.
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.
New vehicle
The first particle filter regeneration
operations may be accompanied by a
"burning" smell, which is per fectly normal.
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.
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.
Brake disc wear
For information on checking brake
disc wear, contact a CITROËN
dealer or a
qualified workshop.
Electric parking brake
This system does not require any
routine servicing. However, in case
of an issue, 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.
Wheels and tyres
The pressure must be checked on
all tyres, including the spare wheel,
when the tyres are "cold", at least
once a
month and before a long
j o u r n ey.
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.

Headlamps and lamps
The headlamps have polycarbonate
lenses with a protective coating.
Do not clean them with a
dry or abrasive
cloth, nor with detergent or solvent
products.
Use a
sponge and soapy water.
The use of a
high pressure jet wash for
cleaning the headlamps, lamps and their
surrounds may damage the lacquer and
seals.
Observe the recommendations on
pressure and distance for jet washing.
First clean persistent stains with a
sponge
and warm soapy water.
Leather
Leather is a natural product. Appropriate
regular care and cleaning is essential for its
durability.
Refer to your vehicle's Maintenance and
Warranty guide for information on all the
special precautions to observe.
AdBlue® (BlueHDi)
To respect the environment and ensure
compliance with the Euro 6 standard, without
adversely affecting the per formance or fuel
consumption of Diesel engines, CITROËN
has taken the decision to equip its vehicles
with a
system that associates 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
17


litres.
Its capacity allows a

driving range of
approximately 5,600

miles (9,000 km), highly
dependent on your driving style.
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 empty.
Driving with under-inflated tyres increases
fuel consumption. Non-compliant tyre
pressure causes premature wear on tyres
and has an adverse effect on the vehicle's
road holding – risk of an accident!
Driving with worn or damaged tyres reduces
the braking and road holding per formance of
the vehicle. It is recommended to regularly
check the condition of the tyres (tread and
sidewalls) and wheel rims as well as the
presence of the valves.
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.
Advice on care and maintenance
Recommendations on the care and
maintenance of your vehicle are given in the
Maintenance and Warranty Guide.
