Access
2Do not put your head or arms through the 
open windows while the vehicle is moving - 
risk of serious injury!
Sunroof
The sunroof consists of a movable glass panel 
that slides over the roof and a blind that can 
be opened independently. Opening the sunroof 
automatically opens the blind.
► 
T
 o operate the panoramic sunroof, use the 
button in the roof console.
 
 
 
 
The sunroof can be operated when the ignition 
is turned on (if the battery is charged enough), 
with the engine running, in STOP mode of Stop 
& Start, and up to 45   seconds after turning off 
the ignition.
Precautions
Do not put your head or arms through the 
sunroof while the vehicle is moving - risk 
of serious injury!
Do not operate the sunroof if transverse 
roof bars are fitted - risk of serious 
damage!
Do not place heavy loads on the movable 
glass panel of the sunroof.
If the sunroof is wet, following a shower 
or washing the vehicle, wait until it is 
completely dry before opening.
Do not operate the sunroof if it is covered by 
snow or ice - risk of damage!
Use only plastic scrapers to remove snow or 
ice from the sunroof.
Regularly check the condition of the 
sunroof seals (e.g.   presence of dust, 
dead leaves).
If using a car wash, check first that the roof is 
correctly closed and keep the high-pressure 
jet at least 30 centimetres from the seals.
Never leave the vehicle with the sunroof 
open.
Operation
When opening the sunroof fully, the movable 
glass moves to a partially open position, then 
slides over the roof. Any intermediate position is 
possible.
Before operating the sunroof control 
button, ensure that no object or person 
might prevent the movement.
Pay particular attention to children when 
operating the sunroof.
If something is trapped when operating the 
sunroof, reverse the movement of the sunroof 
by pressing the appropriate control button.
The driver must ensure that passengers use 
the sunroof correctly.
Any manual intervention on the position of 
the sunroof may disturb the anti-pinch device. 
Perform a reinitialisation.
Anti-pinch system
If the sunroof encounters an obstacle when 
closing, the movement is automatically reversed.
Opening/closing the sunroof
► To open the sunroof, use the part of the 
button located towards the rear.
►
 
T
 o close the sunroof, use the part of the 
button located towards the front.
Operating the button
► Pressing the button beyond its point of 
resistance opens or closes the sunroof fully .
►
 
Pressing the button again stops the 
movement in progress.
►
 
By keeping the button pressed (without going 
beyond the point of resistance), the movement of 
the glass stops when this button is released.

Malfunction
In the event of a malfunction, dashes are 
displayed (orange) instead of the speed setting.
This warning lamp comes on, accompanied by a message and an 
audible signal, to confirm the malfunction.
Have it checked by a CITROËN dealer or a 
qualified workshop.
Lane positioning assist
For more information, refer to the 
General recommendations on the use 
of driving and manoeuvring aids .
 
 
The system identifies the limits of the traffic 
lane and steers the vehicle inside this lane to 
maintain it in the lateral position chosen by the 
driver.
To do this, the system uses a camera placed on 
the upper part of the windscreen.
This function is primarily suitable for driving on 
motorways and main roads.
Activation/Deactivation
Lane positioning assist is automatically activated, 
after selecting
  Highway Driver Assist   mode.
For more information on Highway Driver Assist, 
refer to the corresponding section.
The selection is confirmed by the display of the 
symbols on the instrument panel, representing 
the steering wheel and the side lines.
The colour of the symbols depends on the 
operating state of the system:
(grey)
One or more operating conditions is not met; the 
system is paused.
(green)
All operating conditions are met; the 
system is active.
(orange)
System malfunction.
If the driver no longer wishes to use the system 
for some time, they can deactivate it by pressing 
the ASSIST button again (confirmed by the 
disappearance of the Driving aids mini-view on 
the instrument panel).
The system status is saved when the  ignition is switched off.
Operating conditions
– Adaptive  cruise control active.
–  ESC system operational.
–
 
ASR system activated.
–
 
No trailer detected.
–
 
No 'space-saver' spare wheel in use.
–
 
V
 ehicle not subject to strong lateral g-forces.
–
 
Direction indicators off upon activation of the 
system.
Cruise control
The driver must hold the steering wheel properly.
When cruise control is activated, the symbols are 
displayed in green: with small steering inputs, 
the system steers the vehicle and keeps it in the 
position chosen by the driver in the traffic lane.

Practical information
► Replace the protective plug 2  into the 
carrier   1.
►
 
Stow the towball in its bag to protect it from 
knocks and dirt.
Maintenance
Correct operation is only possible if the towball 
and its carrier are kept clean.
Before cleaning the vehicle with a high-pressure 
jet wash, the towball must be removed and the 
protective plug fitted to the carrier.
Work on the towing device
Contact a CITROËN dealer or a qualified 
workshop.
Roof bars
As a safety measure and to avoid  damaging the roof, it is essential to use 
transverse roof bars approved for your 
vehicle.
Observe the instructions on fitting and use 
contained in the guide supplied with the roof 
bars.
Maximum load distributed over the 
transverse roof bars, for a loading height 
not exceeding 40 cm (except bicycle carrier): 
80   kg.
As this value may change, please verify the 
maximum load quoted in the guide supplied 
with the roof bars.
If the height exceeds 40 cm, adapt the speed 
of the vehicle to the profile of the road to 
avoid damaging the roof bars and the fixings 
on the vehicle.
Be sure to refer to national legislation in order 
to comply with the regulations for transporting 
objects that are longer than the vehicle.
Fitting on longitudinal bars 
 
The transverse bars must be fixed at the 
markings located on the longitudinal bars.
Fitting directly to the roof 
 
You must only attach the transverse bars to 
the four fixing points located on the roof frame. 
These points are concealed by the vehicle doors 
when the doors are closed.
The roof bar fixings have a stud which must be 
inserted into the opening of each fixing point.
Recommendations
Distribute the load uniformly, taking care 
to avoid overloading one of the sides.
Arrange the heaviest part of the load as close 
as possible to the roof.
Secure the load firmly.
Drive gently: the vehicle will be more 
susceptible to the effects of side winds and its 
stability may be affected.
Regularly check the security and tight 
fastening of the roof bars, at least before each 
trip.

Practical information
7Remove the roof bars once they are no longer 
needed.
 
 
Sunroof
Do not operate the sunroof when using 
roof bars - risk of major damage!
Very cold climate screen
(Depending on country of sale)
Only for rechargeable hybrid vehicles.
This removable device prevents the 
accumulation of snow around the radiator 
cooling fan.
It consists of two elements.
 
 
In case of difficulty with installation/
removal
Contact a CITROËN dealer or a qualified 
workshop.
Before any operation, ensure that the 
engine is off and the cooling fan has 
stopped.
It is essential to remove them when:
–  the outside temperature exceeds 
10°C.
–
 
recovery is in progress.
–
 
the speed is above 75 mph (120
   km/h).
Fitting 
 
► Present the corresponding screen.
►  Engage the fixing lugs in the bumper until 
they all clip into position.
►
 
Check that the assembly is firmly held by 
pressing around the edges.
Removing
► Insert a finger in the lower outside corner of 
the screen.
►
 
Pull towards you to guide the unclipping of 
the assembly
.
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.

Practical information
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.
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.
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.
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

In the event of a breakdown
 
► Switch on the compressor by moving the 
switch to position " I
" until the tyre pressure 
reaches 2 bar. The sealant product is injected 
under pressure into the tyre; do not disconnect 
the pipe from the valve during this operation (risk 
of blowback).
If after approximately 7 minutes, the 
pressure of 2 bar is not reached, this 
indicates that the tyre is not repairable; 
contact a CITROËN dealer or a qualified 
workshop for assistance.
►
 
Move the switch to position " O
".
►
 
Disconnect the compressor's electric plug 
from the vehicle's 12
  V socket.

The sealant product is harmful if  swallowed and causes irritation to the 
eyes.
Keep this product out of the reach of children.
The use-by date of the fluid is marked on the 
bottle.
After use, do not discard the bottle into the 
environment; take it to a CITROËN dealer or 
an authorised waste disposal site.
Do not forget to obtain a new bottle of 
sealant, available from a CITROËN dealer or 
a qualified workshop.
 
 
► Drive immediately for approximately 3   miles 
(5   kilometres) at reduced speed (between 
12 and 37 mph (20 and 60
  km/h)) to plug the 
puncture.
►
 
Stop to check the repair 
 and the tyre 
pressure  using the kit.
With a tyre repaired using this type of kit, 
do not exceed a speed of 50
  mph 
(80
 
km/h) and do not drive more than 
125
 
miles (200   km).
Contact a CITROËN dealer or a qualified 
workshop to have the tyre changed.
Checking/adjusting tyre 
pressures
The compressor can be used,  without injecting 
sealant, to check and, if necessary, adjust the 
tyre pressures.
►
 
Remove the valve cap from the tyre and keep 
it in a clean place.
►
 
Uncoil 
 the pipe stowed under the compressor.
►
 
Screw the pipe onto the valve and tighten
