Anti-lock braking system
(ABS) and electronic brake
force distribution (EBFD)
The fixed illumination of this warning
lamp indicates that there is a fault
with the ABS.
The vehicle retains conventional braking. Drive
carefully at moderate speed. If these warning lamps come on,
accompanied by an audible signal
and a message, this indicates a
fault with the electronic brake force
distribution (EBFD) system.
When changing wheels (tyres and rims),
ensure that these are approved for your
vehicle.
Normal operation of the ABS may make
itself felt by slight vibrations of the brake
pedal. In emergency braking, press ver y
firmly and maintain this pressure.
After an impact, have these systems
checked by a CITROËN dealer or a
qualified workshop.
Anti-slip regulation (ASR)/
Dynamic stability control
(DSC)
Operation
These systems are activated automatically
every time the vehicle is started.
They come into operation in the event of a
problem with grip or trajectory.
Deactivating the ASR (depending
on version)
In exceptional conditions (starting a vehicle
which is bogged down, stuck in snow, on soft
ground, etc.), it may be advisable to deactivate
the ASR system, so that the wheels can turn
freely and regain grip.
You must stop as soon as it is safe to do so.
In both cases, have the system checked by a
CITROËN dealer or a qualified workshop as
soon as possible.
This is indicated by this warning
lamp flashing in the instrument
panel.It is however recommended that the system be
reactivated as soon as possible.

urn the "
Grip control" knob to
this position.
Deactivation is confirmed by the
illumination of this warning lamp,
accompanied by a message as
well as illumination of the knob
(depending on version).
The ASR system no longer acts on the
operation of the engine or the brakes in the
event of an involuntary change of trajectory.
Reactivating the ASR (depending
on version)
The system is reactivated automatically every
time the ignition is switched back on or from
30
mph (50 km/h).
Below 30
mph (50 km/h), you can reactivate it
manually:
Safety

In case of towing
Driving with a trailer places greater
demands on the towing vehicle and
requires extra care from the driver.
Side wind
F Take into account the increased sensitivity to wind.
Cooling
Towing a trailer on a slope increases the
temperature of the coolant.
As the fan is electrically controlled, its cooling
capacity is not dependent on the engine speed.
F

T
o lower the engine speed, reduce your
speed.
The maximum towable load on an incline
depends on the gradient and the exterior
temperature.
In all cases, keep a check on the coolant
temperature.
Braking
Towing a trailer increases the braking distance.
To avoid overheating of the brakes, the use of
engine braking is recommended.
Ty r e s
F Check the tyre pressures of the towing vehicle and of the trailer, observing the
recommended pressures.
Lighting
F Check the electrical lighting and signalling on the trailer and the headlamp beam height
of your vehicle. If the exterior temperature is high, it is
recommended that the engine be allowed
to idle for 1 to 2
minutes after the vehicle
comes to a stop, to facilitate its cooling.
F

I

f this warning lamp and the
STOP warning lamp come on,
stop the vehicle and switch off
the engine as soon as possible. New vehicle
Do not pull a trailer before having driven at
least 600
miles (1,000 kilometres).
For more information on Headlamp
adjustment , refer to the corresponding
section.
The rear parking sensors will be
deactivated automatically to avoid the
audible signal if a genuine CITROËN
towbar is used.
Anti-theft protection
Electronic immobiliser
The keys contain an electronic chip which has
a secret code. When the ignition is switched
on, this code must be recognised in order for
starting to be possible.
A few seconds after switching off the ignition,
this system locks the engine control system,
therefore preventing the engine from being
started in the event of a break-in.
If the system fails, as reported by a message,
the engine will not start.
Contact a CITROËN dealer.
For safety and theft protection reasons,
never leave your electronic key in the
vehicle, even when you are close to it.
It is recommended that you keep it with
you.

On vehicles fitted with a manual gearbox,
the arrow may be accompanied by the
gear recommended.
Hill start assist
System which keeps your vehicle immobilised
temporarily (approximately 2 seconds) when
starting on a gradient, the time it takes to
move your foot from the brake pedal to the
accelerator pedal.
It is only active when:
-

t
he vehicle is completely stationary, with
your foot on the brake pedal,
-

c
ertain slope conditions are met,
-

t
he driver’s door is closed.Do not leave the vehicle while it is being
held temporarily in the hill start assist
phase.
If you need to leave the vehicle with the
engine running, apply the parking brake
manually then ensure that the parking
brake warning lamp lights up fixed on the
instrument panel. The hill start assist function cannot be
deactivated. However, use of the parking
brake to immobilise the vehicle interrupts
its operation.
On an ascending slope, with the vehicle
stationar y, the vehicle is held for a shor t
time when you release the brake pedal:
With a manual gearbox, if you are in first gear
or in neutral.
With an automatic gearbox, if you are in
position D or M . On a descending slope, with the vehicle
stationary and reverse gear engaged, the
vehicle is held for a shor t time when you
release the brake pedal.
Malfunction
If a fault in the system occurs, this warning
lamp comes on accompanied by a message.
Contact a CITROËN dealer or a qualified
workshop to have the system checked.
Stop & Start
The Stop & Start system puts the engine
t emporarily into standby – STOP mode – during
stops in traffic (red lights, traffic jams, etc.). The
engine restarts automatically – START mode –
as soon as you want to move off.
The restart takes place instantly, quickly and
silently.
Per fect for urban use, the Stop & Start system
reduces fuel consumption and exhaust
emissions as well as the noise level when
stationary.

Driving

145
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 vehicle's speed must be between 3 mph
a nd 53 mph (5 km/h and 85 km/h) when a
moving vehicle is detected.
The vehicle's speed must not exceed 50
mph
(80 km/h) when a stopped vehicle is detected.
The vehicle's speed must not exceed 37
mph
(60
km/h) when a pedestrian is detected.
The ESC system must not be defective.
The ASR system must not be deactivated.
All passenger seat belts must be fastened.
Driving at a steady speed on roads with few
bends is required.
After an impact, the function automatically
stops operating. Consult a CITROËN
dealer or a qualified workshop to have the
system checked.

Lane Departure Warning
System
System which uses a camera to recognise solid
or broken lines and detects the involuntary
crossing of longitudinal traffic lane markings on
the road.
The camera analyses the image then, if the
driver's attention drops and the speed is higher
than 37 mph (60 km/h), triggers a warning if
there is an unexpected change of direction.
This system is particularly useful on motor ways
and main roads.This system is a driving aid that cannot,
in any circumstances, replace the driver’s
own vigilance.
Manual deactivation/
reactivation
By default, the system is automatically
activated at every engine start-up.
The function is deactivated by a long
press on this button.
The indicator lamp for the button indicates the
status of the function:

Detection
You are alerted by the flashing of
this warning lamp in the instrument
panel, accompanied by an audible
signal.
No warning is transmitted while the direction
indicator is active.
Malfunction
The flashing and then constant illumination of
the warning lamp accompanied by illumination
of the Ser vice warning lamp indicates a fault in
the system.
Have the system checked by a
CITROËN
dealer or a qualified workshop.
Detection may be impeded:
-

i
f the road markings are worn,
-

i
f there is little contrast between the
road markings and the road surface,
-

i
f the windscreen is dirty,
-

i
n certain weather conditions: fog,
heavy rain, snow, shade, bright
sunlight or direct exposure to the sun
(low sun, leaving a tunnel, etc.).
Clean the windscreen regularly,
particularly the area in front of the camera.
The internal sur face of the windscreen can
also become misted around the camera.
In humid and cold weather, demist the
windscreen regularly.
Do not allow snow to accumulate on the
bonnet or roof of the vehicle as this could
mask the camera's view.

If a fault occurs when shifting
to reverse, this warning lamp
comes on in the instrument panel,
accompanied by a message and an
audible signal.
Contact a CITROËN dealer or a qualified
workshop to have the system checked.
In bad or wintry weather, ensure that the
sensors are not covered by mud, ice or
snow.
When reverse gear is engaged, an audible
signal (long beep) indicates that the
sensors may be dirty.
Certain sound sources (motorcycle,
lorry, pneumatic drill, etc.) may trigger
the audible signals of the parking sensor
system. High pressure jet wash
When washing your vehicle, direct the
lance at least 30
cm away from the
sensors.

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.
Practical information

182
Recommendations on storage
AdBlue® freezes at about -11°C and
deteriorates above 25°C. It should be stored in
a cool place 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 ambient
temperature.
Never keep AdBlue
® containers in your
vehicle.
Procedure
In cold weather, before per forming the top-up,
ensure that the temperature is above -11°C.
Otherwise the AdBlue
® may be frozen and so
cannot be poured into the tank.
Park your vehicle in a warmer area for a few
hours to allow the top-up to be carried out. F

12 V battery
Procedure for starting the engine using another
battery or charging a discharged battery.
Lead-acid starter batteries
Batteries contain harmful substances
such as sulphuric acid and lead.
They must be disposed of in
accordance with regulations and must
not, in any circumstances, be discarded
with household waste.
Take used remote control batteries and
vehicle batteries to a special collection
point.
Protect your eyes and face before
handling the battery.
All operations on the battery must be
carried out in a well ventilated area and
away from naked flames and sources of
sparks, so as to avoid the risk of explosion
or fire.
Wash your hands afterwards.
Access to the battery
The battery is located under the bonnet.
For access to the (+) terminal:
F

r
elease the bonnet by activating the internal
control, then the external control,
F

l
ift the bonnet, then hold it in place with its
st ay.
(+) Positive terminal.
It has a quick-release clamp.
(-) Negative terminal.
The battery (-) terminal is not accessible, use
the engine mounting.
Starting using another
battery
When your vehicle's battery is discharged, the
engine can be started using a back-up battery
(external or from another vehicle) and jump
leads or a battery booster. Never try to start the engine by connecting
a battery charger.
Never use a 24
V or higher battery
b o o s t e r.
Check beforehand that the back-up
battery has a nominal voltage of 12 V and
a capacity at least equal to that of the
discharged battery.
The two vehicles must not be in contact
with each other.
Switch off all the electrical consumers
on both vehicles (audio system, wipers,
lighting, etc.).
Make sure that the jump leads are not
close to moving parts of the engine (fan,
belts, etc.).
Do not disconnect the (+) terminal while
the engine is running.

ift the plastic cover on the (+) terminal, if
your vehicle has one.
In the event of a breakdown

204
Never try to charge a frozen battery – risk
of explosion!
If the battery has frozen, have it checked
by a CITROËN dealer or by a qualified
workshop who will check that the internal
components have not been damaged and
that the container has not cracked, which
would mean a risk of toxic and corrosive
acid leaking. If this label is present, it is essential to
use only a 12 V charger to avoid causing
irreversible damage to the electrical
components related to the Stop & Start
system.
Disconnecting the battery
In order to maintain an adequate state
of charge for starting the engine, it is
recommended that the battery be disconnected
if the vehicle is taken out of ser vice for a long
period. Before disconnecting the battery:
F

c
lose all openings (doors, tailgate, windows,
sunroof),
