If fitted on the vehicle, the regulation ISOFIX
mountings are identified by labels.
The mountings comprise three rings for each
seat:


– two front rings, located between the vehicle
seat backrest and cushion.


– one rear ring, to fix the upper strap referred to
as the TOP TETHER.
This ISOFIX mounting system provides fast,
reliable and safe fitting of the child seat in the
vehicle.

Safety
Child lock

It prevents the opening of the sliding side door
from inside.

The ISOFIX child seats are fitted with two
latches which are secured on the two front rings.
Some also have an upper strap which is
attached to the rear ring.
To fasten this strap, remove and stow the head
restraint before installing the child seat on this seat (refit it once the child seat has been
removed). Then, attach the hook to the rear ring
and tighten the upper strap.An incorrectly installed child seat compromises the child's safety in the
event of an accident.
To find out how to install ISOFIX child seats in
the vehicle, refer to the summary table for the
location of ISOFIX child seats.
Summary table of locations for ISOFIX child seats
In accordance with European regulations, this table shows the options for installing ISOFIX child seats on vehicle seats fitted with ISOFIX mountings.
In the case of the universal and semi-universal ISOFIX child seats, the child seat's ISOFIX size category , designated by a letter from A to G, is indicated

Driving
Driving recommendations
► Observe the driving regulations and remain
vigilant whatever the traffic conditions.
► Monitor your environment and keep your
hands on the wheel to be able to react to
anything that may happen any time.
► Drive smoothly, anticipate the need for
braking and maintain a longer safety distance,
especially in bad weather.
► Stop the vehicle to carry out operations that
require close attention (such as adjustments).
► During long trips, take a break every two
hours.
Important!
Never leave the engine running in a
closed space without sufficient
ventilation. Internal combustion engines emit
toxic exhaust gases such as carbon
monoxide. Danger of poisoning and death!
In severe wintry conditions (temperature
below -23°C), let the engine run for 4
minutes before moving off, to ensure the
correct operation and durability of the
mechanical components of your vehicle
(engine and gearbox).
Never drive with the parking brake
applied . Risk of overheating and
damage to the braking system!
Do not park the vehicle or leave the
engine running on a flammable
surface (dry grass, dead leaves, etc.). The
exhaust system of your vehicle is very hot,
even several minutes after the engine stops.
Risk of fire!
Never leave a vehicle unattended with
the engine running. If you have to leave
your vehicle with the engine running, apply
the parking brake and put the gearbox into
neutral or position N or P (depending on the
type of gearbox).
Never leave children inside the vehicle
unsupervised.
To assure the durability of your vehicle and your safety, remember that certain precautions,
described hereafter, should be taken when
driving your vehicle :
Manoeuvre cautiously, at low speed
The dimensions of your vehicle differ from those
of a light vehicle, in width, in height, as well as in
length, and some obstacles will be more difficult
to notice.
Manoeuvre slowly.
Before turning, check that there are no obstacles
at mid-height along the sides.
Before reversing, check that there are no
obstacles, particularly at high level behind the
vehicle. Be aware of the external dimensions, if ladders
are fitted.
Load the vehicle correctly
With a load carried, the vehicle must remain
within the maximum authorised weight, the
Gross Vehicle Weight.
To avoid upsetting the balance of the vehicle,
the load should be centred and the heaviest part
placed on the floor in front of the rear wheels.
It is inadvisable to place heavy loads on a roof
rack.
Loading also implies adherence to the maximum
load of the roof bar anchor points. Adhere to
the maximum permissible weight, according to
CITROËN dealer specifications.
Loads must be securely lashed down.
A load that is not properly secured inside the
vehicle may affect vehicle handling and create a
risk of accident.
If your vehicle is fitted with a drop-side back, the
height and width of the load must remain within
the overall dimensions of the vehicle.
Drive the vehicle in a prudent and efficient
way
Take corners gently.
Anticipate the need to brake as the stopping
distance is increased, particularly on wet or icy
roads.
Be aware of the effect of side winds on the
vehicle.
Effective eco-driving saves fuel; accelerate
progressively, anticipate the need to slow down
and adapt your speed to suit the situation.
Indicate changes of direction well in advance so
that you are seen by other road users.
Take care
The tyres must be inflated to at least the
pressures indicated on the label, even over-
inflated by 0.2 to 0.3 bar for long journeys.
On flooded roads
We strongly advise against driving on flooded
roads, as this could cause serious damage to
the engine or gearbox, as well as to the electrical
systems of your vehicle.


If you are obliged to drive on a flooded road:
► check that the depth of water does not
exceed 15 cm, taking account of waves that
might be generated by other users,
► deactivate the Stop & Start function,
► drive as slowly as possible without stalling. In
all cases, do not exceed 6 mph (10 km/h),
► do not stop and do not switch off the engine.

74
Driving
the whole manoeuvre, in particular using the
mirrors.
Radar
The operation of the radar as well as the
associated functions may be impaired through
the accumulation of dirt (mud, frost, etc.), in
certain difficult weather conditions (very heavy
rain, snow) or if the bumper is damaged.
If the front bumper is to be repainted, contact
a CITROËN dealer or a qualified workshop;
certain types of paint could interfere with the
operation of the radar.
Driving aids camera
This camera and its associated functions
may be impaired or not work if the windscreen
area in front of the camera is dirty, misty,
frosty, covered with snow, damaged or
masked by a sticker.
In humid and cold weather, demist the
windscreen regularly.
Poor visibility (inadequate street lighting,
heavy rain, thick fog, snowfall), dazzle
(headlamps of an oncoming vehicle, low sun,
reflections on a damp road, leaving a tunnel,
alternating shade and light) can also impair
detection performance.
In the event of a windscreen replacement,
contact a CITROËN dealer or a qualified
workshop to recalibrate the camera;
otherwise, the operation of the associated
driving aids may be disrupted.
Other cameras
The images from the camera(s)
displayed on the touch screen or on the
instrument panel may be distorted by the
relief.
In the presence of areas in shade, or in
conditions of bright sunlight or inadequate
lighting, the image may be darkened and with
lower contrast.
Obstacles may appear further away than they
actually are.
Sensors
The operation of the sensors as well as
the associated functions may be disturbed
by sound interference such as that emitted
by noisy vehicles and machinery (e.g. lorries,
pneumatic drills), by the accumulation of
snow or dead leaves on the road or in the
event of damaged bumpers and mirrors.
When reverse gear is engaged, an audible
signal (long beep) indicates that the sensors
may be dirty.
A front or rear impact to the vehicle can
upset the sensors’ settings, which is not
always detected by the system: distance
measurements may be distorted.
The sensors do not systematically detect
obstacles that are too low (pavements, studs)
or too thin (trees, posts, wire fences).
Certain obstacles located in the sensors’ blind
spots may not be detected or may no longer
be detected during the manoeuvre.
Certain materials (fabrics) absorb sound
waves: pedestrians may not be detected.
Maintenance
Clean the bumpers and door mirrors and
the field of vision of the cameras regularly.
When washing your vehicle at high pressure,
direct the spray from at least 30 cm away
from the radar, sensors and cameras.
Mats
The use of mats not approved by
CITROËN may interfere with the operation of
the speed limiter or cruise control.
To avoid any risk of jamming the pedals:
► ensure that the mat is secured correctly,
► never fit one mat on top of another.
Units of speed
Ensure that the units of speed displayed
on the instrument panel (mph or km/h) are
those for the country you are driving in.
If this is not the case, when the vehicle is
stationary, set the display to the required
units of speed so that it complies with what is
authorised locally.
In case of doubt, contact a CITROËN dealer
or a qualified workshop.
Speed Limit recognition
and recommendation
Refer to the General recommendations on the
use of driving and manoeuvring aids .




Using the camera located at the top of the
windscreen, this system detects the following
types of signs and displays the corresponding
information on the instrument panel:
– the maximum authorised speed,
– no overtaking,
– the end of the previous limitations /
restrictions.

Practical information
7Topping up the engine oil level

► Remove the dipstick before topping up.
► Recover the oil filler neck.
► Unscrew the filler cap.
► Install the oil filler neck in the filler hole.
► Top up with oil.
► Remove the oil filler neck from the filler hole.
► Replace the filler cap.
► Replace the dipstick.
Brake fluid
The level of this fluid should be close to
the "MAX" mark. If not, check the brake
pad wear.
To know how often the brake fluid should be
replaced, refer to the manufacturer's servicing
schedule.
If topping up, clean the cap before
replacing it. Use only DOT4 brake fluid
from a sealed canister.
Power steering fluid
The level of this fluid should be close to the "MAX" mark. Check it, with the
vehicle parked on level ground and with the
engine cold, by reading the level on the filler
neck.
Unscrew the cap secured to the dipstick. To
access the reservoir cap, remove the protective
cover by turning its three fixing screws a quarter
turn, then remove the second cover placed on
the cap.
Engine coolant
It is normal to top up this fluid between
two services.
The check and top-up must only be done with
the engine cold.
A low level presents a risk of serious damage to
the engine.
The level of this fluid should be close to the
"MAX" mark but should never exceed it.
If the level is close to or below the " MIN” mark, it
is essential to top up.
When the engine is hot, the temperature of this
fluid is regulated by the fan.
As the cooling system is pressurised, wait at
least one hour after switching off the engine
before carrying out any work.


To gain access to the tank cap, remove the
protective cover by turning its three fixing screws
a quarter of a turn.
In order to avoid the risk of scalding if you need
to top up in an emergency, wrap 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 to the required level.
Check the coolant level regularly
according to the use of your vehicle
(every 3,000 miles (5,000 km) / 3 months).

► Reconnect the hose I and connect pipe B to
its location.
The cartridge contains ethylene glycol, which is harmful if swallowed and irritates
the eyes.
It must be kept out of the reach of children.
After use, do not discard the cartridge in standard waste, take it to a
CITROËN dealer or an authorised waste
disposal site.
Spare wheel
Parking
► Park the vehicle where it does not block
traffic: the ground must be level, stable and
non-slippery.
► If the road is sloping or damaged, place an
object under the wheels to act as a chock.
► With a manual gearbox, engage first gear
then switch off the ignition to block the wheels.
► Apply the parking brake and check that the
warning lamp is on in the instrument panel.
► The passengers must get out of the vehicle
and wait where they are safe.
► Put on the high visibility vest and signal that
the vehicle is immobile by using the devices
envisaged by the legislation in force in the
country where you are driving (warning triangle,
hazard warning lamps, etc.).
► Equip yourself with the tools.

the Identification markings of the
vehicle, and in particular the tyre pressure
label, refer to the corresponding section.
Changing a bulb
The headlamps have polycarbonate lenses with a protective coating:
► do not clean them using a dry or
abrasive cloth, nor with a detergent or
solvent product,
► use a sponge and soapy water or a pH
neutral product,
► when using a high pressure washer on
persistent marks, do not keep the lance
directed towards the lamps or their edges for
too long, so as not to damage their protective
coating and seals.
Changing a bulb must only be done with
the ignition off and after the lamp has
been switched off for several minutes - Risk
of serious burns!
► Do not touch the bulb directly with your
fingers, use a lint-free cloth.
It is essential only to use anti-ultraviolet
(UV) type bulbs, so as not to damage the
headlamp.
Always replace a failed bulb with a new bulb
with the same type and specification.
