If the camera has confirmed
the presence of a vehicle or a
pedestrian, this warning lamp
flashes once the function is acting
on the vehicle's brakes.
Using the camera, this function acts on the
vehicle's braking system.
Important : if operation of the
automatic emergency braking is
triggered, you should take back
control of your vehicle and brake
with the pedal to add to or finish the
automatic braking action.
The driver can take back control of the vehicle
at any time by sharply turning the steering
wheel and/or pressing the accelerator pedal.
The point at which braking is triggered
may be adjusted according to the driving
actions from the driver, such as movement
of the steering wheel or pressing the
accelerator pedal.
Operation of the function may be felt by
slight vibration in the brake pedal.
If the vehicle comes to a complete stop,
the automatic braking is maintained for 1
to 2

seconds. With a manual gearbox, in the event of
automatic emergency braking until the
vehicle comes to a complete stop, the
engine may stall.
With an automatic gearbox, in the event
of automatic emergency braking until the
vehicle comes to a complete stop, keep
the brake pedal down to stop the vehicle
from starting off again.
Specific conditions for operation

The driver can take control at any time by
gripping the steering wheel.This manoeuvring assistance system
cannot, in any circumstances, replace the
need for vigilance on the part of the driver.
The driver must remain in control of their
vehicle ensuring that the space remains
clear throughout the manoeuvre.
In some circumstances, the sensors may
not detect small obstacles located in their
blind spots.
The Park Assist system cannot work with
the engine off. C.
Bay parking.
During manoeuvring phases, the steering
wheel per forms rapid turns: do not hold
the steering wheel, do not put your hands
between the spokes of the steering wheel.
Watch out for any object that could block
the manoeuvre (loose clothing, scar ves,
ties, etc.) - Risk of injury!
When the Park Assist is active, it prevents
the Stop & Start going into STOP mode.
In STOP mode, activating Park Assist
restarts the engine. The Park Assist system takes control
of the assistance for a maximum of
4
manoeuvre cycles. The function is
deactivated after these 4 cycles. If you
think that your vehicle is not positioned
correctly, you should then take control of
the steering to carry out the manoeuvre.
During phases of entry into and exit from a
parking space, the system provides visual
and audible information to the driver in order
to make the manoeuvres safe. It may be
necessary to move for wards and backwards
more than once.
The Park Assist system provides assistance for
the following manoeuvres:
B.Exit from a parallel parking space. The sequence of manoeuvres and the
driving instructions are displayed on the
touch screen.
The assistance is activated:
the display of this symbol and
a speed limit indicate that
the steering manoeuvres are
controlled by the system: do not
touch the steering wheel.
The assistance is deactivated:
the display of this symbol
indicates that the steering
manoeuvres are no longer
controlled by the system:
you must take control of the
steering.
You should always check the surroundings
of your vehicle before starting a
manoeuvre.

Fuel cut- of f
Your vehicle is equipped with a safety device
which cuts off the fuel supply in the event of a
collision.
Misfuel prevention
(Diesel)
(Depending on country of sale)
Mechanical device which prevents filling the
tank of a Diesel vehicle with petrol. It helps
avoid the risk of engine damage that can result
from filling with the wrong fuel.
Operation
When a petrol filler nozzle is introduced into the
Diesel tank, it comes into contact with the flap.
The system remains closed and prevents filling.It remains possible to use a fuel can to fill
the tank.
In order to ensure a good flow of fuel,
do not place the nozzle of the fuel can in
direct contact with the flap of the misfuel
prevention device and pour slowly.
Travelling abroad
As Diesel fuel pump nozzles may be
different in other countries, the presence
of the misfuel prevention device may make
refuelling impossible.
Not all Diesel vehicles are fitted with
misfuel protection, so before travelling
abroad, we recommend that you check
with the CITROËN dealer network whether
your vehicle is suitable for the fuel pumps
in the country in which you intend to travel.
Do not persist but introduce a Diesel type
filler nozzle.
Snow chains
In wintry conditions, snow chains
improve traction as well as the
behaviour of the vehicle when
braking.
Snow chains must be fitted only to the
front wheels. They must never be fitted to
"space-saver" type spare wheels.
Take account of the legislation in force in
your country on the use of snow chains
and the maximum authorised speed.
Installation tips
F If you have to fit the chains during a journey, stop the vehicle on a flat sur face on the side
of the road.

Checking levels
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. The fluid must comply with the
manufacturer's recommendations 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
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 and dispose of
it in the containers reser ved for this
purpose.
Engine oil level
The check is carried out either when
the ignition is switched on using the
oil level indicator in the instrument
panel for vehicles so equipped, or
using the dipstick. To ensure that the reading is correct, your
vehicle must be parked on a level sur face
with the engine having been off for more
than 30


minutes.
It is normal to top up the oil level between
two ser vices (or oil changes). CITROËN
recommends that you check the level, and top
up if necessary, every 3,000 miles (5,000 km).

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.

Practical information

178
When the engine is warm, the temperature of
the coolant is regulated by the fan.
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 the risk of scalding when you need to
top up in an emergency, place 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 the coolant.The cooling fan may star t after
switching off the engine: take care
with articles and clothing that might be
caught by the fan blades.
Fluid specification
The fluid must conform to the manufacturer's
recommendations.
Screenwash fluid level
A low coolant level presents a risk of serious
damage to your engine.
Top up the fluid when necessary.Fluid specification
The screenwash fluid must be topped up with a
ready for use mix.
In winter (temperatures below zero), a fluid with
antifreeze must be used that is appropriate for
the prevailing conditions, in order to preser ve
the elements of the system (pump, tank, ducts,
e t c .) .
Filling with pure water is prohibited under all
circumstances (risk of freezing, limestone
deposits, etc.).
Diesel fuel additive level
(Diesel with particle filter)
The additive tank minimum level is
indicated by fixed illumination of this
warning lamp, accompanied by an
audible signal and a message that
the particle filter additive level is
too low.
To p p i n g u p
The reser voir must be topped up without delay
by a CITROËN dealer or a qualified workshop.
AdBlue level
An alert is triggered once the reser ve level is
reached.
To avoid the vehicle being immobilised as per
regulations, you must top up with AdBlue.
For more information on AdBlue
® and the SCR
system, and, in particular, topping it up, 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.
Other wise, have them checked by a CITROËN
dealer or a qualified workshop.
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.
Practical information

179
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).
