Driving
The system assesses the driver's level of alertness, fatigue and distraction by
identifying trajectory changes in relation to the
lane markings.
To do this, the system uses a camera, placed on
the upper part of the windscreen.
This system is particularly suited to fast roads
(speed higher than 43 mph (70
km/h)).
At a first alert level, the driver is warned by the
message "Be vigilant!", accompanied by an
audible signal.
After three first-level alerts, the system triggers
a further alert with the message " Dangerous
driving: take a break", accompanied by a more
pronounced audible signal.
In certain driving conditions (poor road
surface or strong winds), the system may
give alerts independent of the driver's level of
vigilance.
The following situations may interfere with the operation of the system or
prevent it from working:
–

lane markings absent, worn, hidden (snow
,
mud) or multiple (roadworks);
–

close to the vehicle ahead (lane markings
not detected);
–


roads that are narrow
, winding, etc.
Parking sensors
For more information, refer to the
General recommendations on the use
of driving and manoeuvring aids .


This system detects and signals the proximity of
obstacles (e.g.
pedestrian, vehicle, tree, barrier)
using sensors located in the bumper.
Rear parking sensors
► Engage reverse gear to start the system
(confirmed by an audible signal).
The system is switched off when reverse gear is
disengaged.
Audible assistance

The system signals the presence of obstacles
within the sensors’ detection zone.
The proximity information is given by an
intermittent audible signal, the frequency of
which increases as the vehicle approaches the
obstacle.
When the distance between the vehicle and
the obstacle becomes less than about thirty
centimetres, the audible signal becomes
continuous.
The sound emitted by the speaker (right or
left) indicates the side on which the obstacle is
located.
Adjusting the audible signalDepending on version, with
CITROËN Connect Nav, pressing
this button opens the window for adjusting the
volume of the audible signal.
Visual assistance

This supplements the audible signal, without
taking account of the vehicle's trajectory, by
displaying bars on the screen that represent the
distance between the obstacle and the vehicle
(white: more distant, orange: close, red: very
close).

128
Driving

The reversing camera is activated automatically
when reverse gear is engaged.
The image is displayed on the touch screen.
The reversing camera function may be supplemented by the parking sensors.


The blue lines 1 indicate the general direction of
the vehicle (the gap corresponds to the width of
your vehicle including the mirrors).
The red line 2 represents a distance of about
30
cm beyond the edge of your vehicle's rear
bumper.
The green lines 3 represent distances of about 1
and 2 metres beyond the edge of your vehicle's
rear bumper.
The turquoise curves 4 show the maximum
turning angle in either direction.
Opening the tailgate causes the display
to disappear.
Clean the reversing camera regularly
using a soft, dry cloth.
Top Rear Vision - 360 vision
For more information, refer to the
General recommendations on the use
of driving and manoeuvring aids .
With the engine running, these systems allow
views of your vehicle’s close surroundings to be
displayed on the touch screen using one camera
for Top Rear Vision and two cameras for 360
vision.




The screen is divided into two parts with a
contextual view and a view from above the
vehicle in its close surroundings.
The parking sensors supplement the information
on the view from above the vehicle.
Various contextual views may be displayed:
–
Standard view
.
–

180° view
.
–

Zoom view
.
AUTO mode is activated by default.
In this mode, the system chooses the best
view
to display (standard or zoom).
You can change the type of view at any time
during a manoeuvre.
►

• "AUTO view".
The display is immediately updated with the type
of view selected.
The system status is not saved when the ignition
is switched off.
Operating principle

Using one or two cameras, the close
surroundings of the vehicle are recorded whilst
manoeuvring at low speed.
An image from above your vehicle in its close
surroundings is reconstructed (represented
between the brackets) in real time and as the
manoeuvre progresses.
It facilitates the alignment of your vehicle when
parking and allows obstacles close to the vehicle
to be seen. It is automatically deleted if the
vehicle remains stationary for too long.
With 360 vision, the image is created using
both cameras, when going forward and when
reversing.
When the function is activated, it is possible
that the view from above is not displayed. If the system is activated when the vehicle has
already moved, the view from above can be fully
displayed.
Top Rear Vision

Stop & Start
Before doing anything under the bonnet,
you must switch off the ignition to avoid any
risk of injury resulting from an automatic
change to START mode.
Electric motor
Take care with objects or clothing that
could be caught in the blades of the cooling
fan or in certain moving components - risk of
strangulation and serious injury!
Before carrying out any work under the
bonnet, you must switch off the ignition, check
that the READY indicator lamp is off on the
instrument panel and disconnect the charging
nozzle if it is plugged in.
The location of the interior bonnet release lever prevents the bonnet being
opened when the left-hand front door is
closed.

Checking levels
Check all of the following levels regularly in
accordance with the manufacturer's service
schedule. Top them up if required, unless
otherwise indicated.
If a level drops significantly, have the
corresponding system checked by a CITROËN
dealer or a qualified workshop.
The fluids must comply with the manufacturer's requirements 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 and
very corrosive.
Do not discard used oil or fluids into
sewers or onto the ground.
Empty used oil into the containers reserved
for this purpose at a CITROËN dealer or a
qualified workshop.
Engine oil
The level is checked, with the engine having been switched off for at least 30
minutes and on level ground, either using the oil
level indicator in the instrument panel when the
ignition is switched on (for vehicles equipped
with an electric gauge), or using the dipstick.
It is normal to top up the oil level between two
services (or oil changes). It is recommended
that you check the level, and top up if necessary,
every 3,000 miles (5,000 km).
In order to maintain the reliability of the
engine and emissions control system,
never use additives in the engine oil.
Checking using the dipstick
For the location of the dipstick, please refer
to the illustration of the corresponding engine
compartment.
►

Grasp the dipstick by its coloured grip and
pull it out completely

.
►

Wipe the end of the dipstick using a clean,
lint-free cloth.


► Reinsert the dipstick and push fully down,
then pull it out again to visually check the oil
level: the correct level is between marks A
(max)
and B (min).
Do not start the engine if the level is:
–

above mark
A: contact a CITROËN dealer or a
qualified workshop.
–

below mark B

: top up the engine oil
immediately.

Checks
Unless otherwise indicated, check these
components in accordance with the
manufacturer's service schedule and according
to your engine.
Otherwise, have them checked 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.
12 V battery
The battery does not require any maintenance.
Check regularly that the terminals are correctly
tightened (versions without quick-release
terminals) and that the connections are clean.
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)
The start of clogging of the particle filter is
indicated by the temporary lighting 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.
Following prolonged operation of the
vehicle at very low speed or at idle, you
may, in exceptional circumstances, notice
water vapour coming from the exhaust while
accelerating. These emissions have no
impact on the vehicle’s behaviour and the
environment.
New vehicle
During the first few particle filter
regeneration operations, you may notice a
"burning" smell. This is perfectly normal.

Automatic gearbox
The gearbox does not require any maintenance (no oil change).
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.
Electric parking brake
This system does not require any routine servicing. However, in the event of a
problem, 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.
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/drum wear
For any information on checking brake
disc/drum wear, contact 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 energy
consumption. Non-compliant tyre
pressures cause tyres to wear prematurely
and have an adverse effect on the vehicle's
road holding - risk of accident! Driving with worn or damaged tyres reduces the
braking and road holding performance of the
vehicle. Regularly check the condition of the
tyres (tread and sidewalls) and rims as well as
the presence of the valve caps.
When the wear indicators no longer appear set
back from the tread, the depth of the grooves is
less than 1.6 mm; replace the tyres as soon as
possible.
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.
Always mark the direction of rotation on the tyres
that will be stored when fitting winter or summer
tyres. Store them in a cool, dry place and away
from direct exposure to the sun's rays.
Winter or 4-seasons tyres can be
identified by this symbol on their
sidewalls.
Shock absorbers
It is not easy for drivers to detect when
shock absorbers are worn. Nevertheless,
the shock absorbers have a major impact on
road holding and braking performance.
For your safety and driving comfort, it is
important to have them regularly checked by a
CITROËN dealer or a qualified workshop.
