► press button 5 again to save the suggested
speed.
The speed is immediately displayed as the new
speed setting on the instrument panel.
Temporarily exceeding the
speed setting
► Press the accelerator pedal down fully .The speed limiter is deactivated temporarily and
the displayed speed setting flashes.
► Release the accelerator pedal to return to below the programmed speed.
When the limit speed is exceeded but this is not
due to action by the driver (in case of a steep
slope, for example), an audible signal triggers
immediately.
On a steep descent or in the event of
sharp acceleration, the speed limiter will
not be able to prevent the vehicle from
exceeding the speed setting.
Brake if necessary to control the speed of
your vehicle.
Once the speed of the vehicle returns to the
programmed setting, the speed limiter functions
again: the display of the speed setting becomes
fixed again.
Switching off
► Turn the thumbwheel 1 to the "OFF" position:
the display of information on the speed limiter
disappears.
Malfunction

The display of dashes (flashing then fixed)
indicates a fault with the speed limiter.
Have it checked by a CITROËN dealer or a
qualified workshop.
Cruise control - particular
recommendations
For the safety of everyone, only use the
cruise control where the driving
conditions allow running at a constant speed
and keeping an adequate safety distance.
Remain vigilant when the cruise control
is activated. If you hold one of the speed
setting modification buttons down, a very
rapid change in the speed of your vehicle may
occur.
When descending a steep hill , the cruise
control system cannot prevent the vehicle
from exceeding the set speed. Brake if
necessary to control the speed of your
vehicle.
On steep climbs or when towing, the set
speed may not be reached or maintained.
Exceeding the programmed speed
setting
You can temporarily exceed the speed
setting by pressing the accelerator pedal (the
programmed speed flashes).
To return to the speed setting, release the
accelerator pedal (when the set speed is
reached again, the displayed speed stops
flashing).
Operating limits
Never use the system in the following
situations:
– In an urban area with the risk of pedestrians crossing the road.– In heavy traffic.– On winding or steep roads.– On slippery or flooded roads.– In poor weather conditions.– Driving on a speed circuit.– Driving on a rolling road.– When using snow chains, non-slip covers or studded tyres.
Cruise control
Refer to the General recommendations on the
use of driving and manoeuvring aids and to
Cruise control - particular recommendations.
This system automatically keeps the vehicle’s speed at the cruise value
programmed by the driver (speed setting), without using the accelerator pedal.
The cruise control is switched on manually.
It requires a minimum vehicle speed of 25 mph
(40 km/h).With a manual gearbox, third gear or higher must
be engaged.
With an automatic gearbox, mode D or second gear or higher in mode M must be engaged.
The cruise control remains active after changing gear, regardless of the gearbox
type, on engines fitted with Stop & Start.
Switching off the ignition cancels any
speed setting.

Driving
► Pressing button 4 again restores operation of
the cruise control (ON).
Changing the cruise speed
setting
The cruise control must be active.
To change the cruise speed setting, based on
the vehicle’s current speed:
► In +/- 1 mph (1.6 km/h) steps, briefly press button 2 or 3 as often as necessary.► Continuously , in steps of +/- 5 mph (8 km/h), press and hold button 2 or 3.
Pressing and holding button 2 or
3 results in a rapid change in the speed of your vehicle.
As a precaution, we recommend setting a cruise speed similar to the vehicle’s
current speed, to avoid any sudden
acceleration or deceleration.
To modify the cruise speed setting using memorised speed settings and from the touch
screen:
► press button 5 to display the six memorised
speed settings,
► press the button for the desired speed setting.
This setting becomes the new cruise speed.
To modify the cruise speed setting using the speed suggested by the Speed Limit Recognition
and Recommendation shown on the instrument
panel:
► Press button 5 once; a message is displayed
to confirm the memorisation request.
► Press button 5 again to save the suggested
speed.
The speed is immediately shown on the
instrument panel as the new speed setting.
Temporarily exceeding the
speed setting
If needed (for overtaking, etc.) it is possible to
exceed the programmed speed by pressing the
accelerator pedal.
The cruise control is temporarily overridden and
the programmed speed setting flashes.
To return to the speed setting, release the
accelerator pedal.
Once the vehicle has returned to the
programmed speed, the cruise control takes over
again: the display of the programmed speed
setting becomes steady again.
When descending a steep hill, the cruise
control system cannot prevent the
vehicle from exceeding the programmed
speed.
You may have to brake to control the speed of
your vehicle. In this case, the cruise control is
automatically paused. To activate the system again, with the speed
of the vehicle above 25 mph (40 km/h), press
button 4.
Switching off
► Turn the thumbwheel
1 to the "OFF" position:
the cruise control information disappears from
the screen.
Malfunction

The display of dashes (flashing then fixed)
indicates a malfunction with the cruise control
system.
Have it checked by a CITROËN dealer or a
qualified workshop.
Active Safety Brake with Collision Risk Alert and
Intelligent emergency
braking assistance
Refer to the General recommendations on the
use of driving and manoeuvring aids .


This system:– warns the driver that their vehicle is at risk of collision with the vehicle in front or a pedestrian.– reduces the vehicle's speed to avoid a collision or limit its severity.
This system is comprised of three functions:
– Collision Risk Alert.
– Intelligent emergency braking assistance.– Active Safety Brake (automatic emergency braking).

The vehicle has a camera located at the top of
the windscreen.
This system does not avoid the need for
vigilance on the part of the driver.
This system is designed to assist the driver
and improve road safety.
It is the driver's responsibility to continuously
monitor the state of the traffic, observing the
driving regulations.
As soon as the system detects a potential obstacle, it prepares the braking
circuit in case automatic braking is needed.

Collision Risk Alert
This function warns the driver that their vehicle
is at risk of a collision with the vehicle in front or
with a pedestrian present in their traffic lane.
Operation
Depending on the degree of risk of collision
detected by the system and the alert trigger
threshold chosen by the driver, several different
levels of alert may be triggered and displayed in
the instrument panel or on the head-up display.
The system takes account of the vehicle
dynamics, the speed of your vehicle and the one
in front, the environmental conditions and the
operation of the vehicle (actions on the pedals,
the steering wheel, etc.) to trigger the alert at the
best moment.
Level 1 (orange): visual alert only,
indicating that the vehicle in front is very
close.
The message "Vehicle close" is displayed.Level 2 (red): visual and audible alert,
indicating that a collision is imminent.
The message "Brake! " is displayed.
Level 3: in some cases, a vibration alert in the
form of micro-braking can be given, confirming
the risk of collision.
Where the speed of your vehicle is too
high approaching another vehicle, the
first level of alert may not be displayed: the
level 2 alert may be displayed directly.
Important: the level 1 alert is not displayed
when there is a stationary obstacle or when
the "Close" trigger threshold has been
selected.
Modifying the alert trigger threshold
This trigger threshold determines the sensitivity
with which the function warns of the risk of
collision.
► Select one of the three pre-defined thresholds:– "Distant".– “Normal".– “Close".
The last threshold selected is memorised when
the ignition is switched off.
Without audio system
► In the "DRIVE ASSIST" menu on the
instrument panel display, activate/deactivate
"COLLISION ALT" (Automatic emergency
braking).
► Then change the alert threshold.
With audio system
► In the "Personalisation-
configuration " menu, activate/deactivate
"Auto. emergency braking".
► Then change the alert threshold.
With touch screen
► In the Driving / Vehicle menu, select
the "Vehicle settings" tab, then
"Security" and activate/deactivate " Collision
risk and auto. braking ".
► Then change the alert threshold.► Press "Confirm" to save the change.
Intelligent emergency
braking assistance
If the driver brakes, but not sufficiently to avoid a
collision, this system will supplement the braking,
within the limits of the laws of physics.
This assistance will only be provided if the driver
presses the brake pedal.
Active Safety Brake

This function, also called automatic emergency
braking, intervenes following the alerts if the
driver does not react quickly enough and does
not operate the vehicle's brakes.
It aims to reduce the speed of impact or avoid a
collision where the driver fails to react.
Operation
The system operates under the following
conditions:
– The vehicle's speed does not exceed 37 mph (60 km/h) when a pedestrian is detected.
– The vehicle's speed does not exceed 50 mph (80 km/h) when a stationary vehicle is detected.

AUTO mode

This mode is activated by default.
Using sensors in the rear bumper, the automatic
view changes from the rear view (standard) to
the view from above (zoom) as an obstacle is
approached at the level of the red line (less than
30 cm) during a manoeuvre.
Standard view

The area behind the vehicle is displayed on the
screen. The blue lines
1 represent the width of your
vehicle, with the mirrors unfolded; their direction
changes depending on the position of the
steering wheel.
The red line 2 represents a distance of 30 cm
from the rear bumper; the two blue lines 3 and 4
represent 1 m and 2 m, respectively.
This view is available with AUTO mode or in the
view selection menu.
Zoom view

The camera records the vehicle's surroundings
during the manoeuvre in order to create a
view from above the rear of the vehicle in its
near surroundings, allowing the vehicle to be
manoeuvred around obstacles nearby.
This view is available with AUTO mode or in the
view selection menu.

6Activating the function deactivates the Blind Spot Monitoring System.
You can deactivate the function at any time until the parking space entry or exit
manoeuvre begins, by pressing the arrow
located in the top left-hand corner of the
display page.
Selecting the type of manoeuvre

A manoeuvre selection page is displayed on the
touch screen: by default, the "Entry" page if the
vehicle has been running since the ignition was
switched on, otherwise, the "Exit" page.
► Select the type and side of the manoeuvre to activate the parking space search.
The selected manoeuvre can be changed at
any time, even while searching for an available
space.
Parking space search
► You should drive at a distance of between 0.50 m and 1.50 m from the row of parked vehicles, without ever exceeding 19 mph (30 km/h), until the system finds an available space.
The parking space search is suspended at
higher speeds. The function is automatically
deactivated if the vehicle speed exceeds 31 mph
(50 km/h).
For "parallel" parking, the space must
measure at least the length of your
vehicle plus 0.60 m.
For "bay" parking, the space must be at least
as wide as your vehicle plus 0.70 m.
If the parking sensors function has been
deactivated in the Driving/Vehicle touch
screen menu, it will be automatically
reactivated when the system is activated.


When the system finds an available space, " OK"
is displayed on the parking view, accompanied
by an audible signal.
Preparing for the manoeuvre
► Move very slowly until the request to stop the vehicle is displayed: " Stop the vehicle“,
accompanied by the “ STOP” sign and an audible
signal.
Once the vehicle has stopped, an instructions
page is displayed on the screen.
► To prepare for the manoeuvre, follow the instructions.
The start of the manoeuvre is indicated by the
"Manoeuvre under way" onscreen message
and an accompanying audible signal.
Reversing is indicated by this message:
“Release the steering wheel, reverse ”.
The Top Rear Vision and the parking sensors
are automatically activated to help you monitor
the area immediately surrounding your vehicle
during the manoeuvre.
During the manoeuvre
The system controls the vehicle’s steering. It gives instructions on the manoeuvring direction
when starting "parallel" entry and exit parking
manoeuvres, and for all "bay" entry manoeuvres.
These instructions are displayed as a symbol
accompanied by a message:
"Reverse".

Practical information
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)
When the particle filter is approaching saturation, this warning lamp comes on
temporarily, accompanied by a message warning
of the risk of filter clogging.
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,
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 while
accelerating. This has no impact on the
vehicle’s behaviour or the environment.
New vehicle
During the first few particle filter
regeneration operations, you may notice a
"burning" smell. This is perfectly 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, 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 wear
For information on checking brake disc
wear, contact a CITROËN dealer or a
qualified workshop.
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.
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 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 performance 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.
When the wear indicators no longer appear set
back from the tread, the depth of the grooves is
less than 1.6 mm; it is imperative to replace the
tyres.
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.

VHOHFWPRGHP
to lock the wheels, apply the parking brake,
unless it is programmed to be in automatic
mode, and switch off the ignition.
Check for the fixed illumination of the parking
brake indicator lamps in the instrument panel.
The occupants must get out of the vehicle
and wait where they are safe.
If necessary, place a chock under the wheel
diagonally opposite the wheel to be changed.
Never go underneath a vehicle raised using a
jack; use an axle stand.
Wheel with wheel trim
When removing the wheel , first remove
the wheel trim by pulling at the valve aperture
using the wheelbrace.
When refitting the wheel , refit the wheel
trim, starting by placing its aperture in line
with the valve and then pushing it into place
all round its edge with the palm of your hand.


– If the vehicle has steel wheels, remove the wheel trim.– If the vehicle has alloy wheels, remove the central bolt cover using tool 7.– If the vehicle is so equipped, fit security bolt socket 2 to wheelbrace 5 to slacken the security
bolt.
– Slacken the other bolts using the wheelbrace 5 only.

► Place the foot of jack 6 on the ground and ensure that it is directly below the front A or rear B jacking point on the underbody, whichever
is closest to the wheel to be changed.


► Extend jack 6 until its head comes into contact with jacking point A or B; contact area A
or B on the vehicle must be properly inserted
into the central part of the head of the jack.
► Raise the vehicle until there is sufficient space between the wheel and the ground to
admit the spare (not punctured) wheel easily.
Ensure that the jack is stable. If the
ground is slippery or loose, the jack may
slip or collapse - risk of injury!
Take care to position the jack strictly at
one of the jacking points A or B under the
vehicle, ensuring that the head of the jack is
centred under the contact area of the vehicle.
Otherwise, there is a risk of damage to the
vehicle and/or of the jack collapsing - risk of
injury!
