Ease of use and comfort
Automatic "electrochrome" model

The electrochrome system uses a sensor that
detects the level of exterior brightness and that
coming from the rear of the vehicle, in order to
automatically and gradually switch between day
and night usage.
To ensure optimum visibility while manoeuvring, the mirror automatically
brightens when reverse gear is engaged.
The system is deactivated if the load in the
boot exceeds the height of the load space
cover or if the load space cover has items
placed on it.
Rear bench seat
Bench seat with fixed cushions and split folding
backrests (2/3-1/3) to adapt the boot load space.
The rear seat cushion remains fixed. To increase the boot loading volume, tilt the
bench seat backrest.
Rear head restraints

They have two positions:
– A high position , for when the seat is in use:
►

Pull the head restraint fully up.
–

A low position , for stowing, when the seat is
not in use: ►

Press the lug
A to release the head
restraint and push it down.
The rear head restraints can be removed.
Removing a head restraint
► Release the backrest using control 1 .
► T ilt the backrest slightly forwards.
►

Pull the head restraint fully up.
►


Press the lug
A to release the head restraint
and remove it completely.
Refitting a head restraint
► Insert the head restraint rods into the guides
in the corresponding backrest.
►

Push the head restraint fully down.
►


Press the lug
A to release the head restraint
and push it down.
Never drive with passengers seated at
the rear when the head restraints are
removed; the head restraints should be in
place and in the high position.
The head restraint for the centre seat
and those for the outer seats are not
interchangeable.
Folding the backrests
Manoeuvring the backrests should only
be done when the vehicle is stationary.
First steps:
►

Lower the head restraints.
►


If necessary
, move the front seats forward.
►

Check
that no person or object might interfere
with the folding of the backrests (e.g.
clothing,
luggage).


► Press the backrest release grip 1 .

windscreen, or from the inside in air recirculation
mode.
Controls
Depending on version, the controls are
accessible in the Climate touch screen menu
or are grouped together on the centre console
panel.
Air distribution

1. Windscreen demisting/de-icing vents
2. Front side window demisting/de-icing vents
3. Adjustable and closable side air vents
4. Adjustable and closable central air vents
5. Air outlets to the front footwells
6. Air outlets to the rear footwells
7. Adjustable and closable air vents
Advice
Using the ventilation and air
conditioning system
►

T

o ensure that air is distributed evenly,
keep the external air intake grilles at the base
of the windscreen, the nozzles, the vents, the
air outlets and the air extractor in the boot
free from obstructions.
►

Do not cover the sunshine sensor located
on the dashboard; this sensor is used to
regulate the automatic air conditioning
system.
►


Operate the air conditioning system for at
least 5 to 10 minutes once or twice a month to
keep it in good working order

.
►

If the system does not produce cold air
,
switch it off and contact a CITROËN dealer or
a qualified workshop.
When towing a large load on a steep gradient
in high temperatures, switching off the air
conditioning increases the available engine
power, enhancing the towing capacity.
Avoid driving for too long with the ventilation off or with prolonged operation
of interior air recirculation. Risk of misting and
deterioration of the air quality!
If the interior temperature is very high
after the vehicle has stood for a long
time in the sunshine, air the passenger
compartment for a few moments.
Put the air flow control at a setting high
enough to quickly change the air in the
passenger compartment.
Condensation created by the air
conditioning results in a discharge of
water underneath the vehicle. This is perfectly
normal.
Servicing the ventilation and air
conditioning system
►

Ensure that the passenger compartment
filter is in good condition and have the filter
elements replaced regularly

.
We recommend using a composite passenger
compartment filter. Its specific active additive
helps protect against polluting gases and bad
smells.
►

T

o ensure correct operation of the
air conditioning system, have it checked
according to the recommendations in the
Manufacturer’s service schedule.
Stop & Start
The heating and air conditioning systems
only operate when the engine is running.
Temporarily deactivate the Stop & Start
system to maintain a comfortable temperature
in the passenger compartment.

Lighting and visibility
4upwards or downwards, depending on the side
of the traffic (e.g. when parking on the right, push
the lighting control stalk down to light up on the
left).
This is confirmed by an audible signal and the
lighting of the corresponding direction indicator
lamp on the instrument panel.
►

T
o switch off the parking lamps, return the
lighting control stalk to the central position.
Automatic illumination of lamps
With the lighting control stalk in the “ AUTO”
position and if a low level of exterior brightness
is detected by the rain/sunshine sensor, the
sidelamps and dipped beam headlamps are
switched on automatically, without any action on
the part of the driver. They may also come on if
rain is detected, at the same time as automatic
operation of the windscreen wipers.
As soon as the brightness returns to a sufficient
level or after the windscreen wipers are switched
off, the lamps are switched off automatically.
Malfunction
In the event of a malfunction of the rain/
sunshine sensor, the vehicle’s lamps
come on and this warning lamp is displayed on
the instrument panel, accompanied by an
audible signal and/or the display of a message.
Have it checked by a CITROËN dealer or a
qualified workshop.
Do not cover the rain/sunshine sensor
located at the top centre of the
windscreen behind the interior rear view
mirror; the associated functions would no
longer be controlled.
In fog or snow, the rain/sunshine sensor
may detect sufficient light. For this
reason, the lighting will not come on
automatically.
The inner surface of the windscreen may become misted up and affect the proper
operation of the rain/sunshine sensor.
In humid and cold weather, demist the
windscreen regularly.
Headlamp beam height
adjustment




To avoid dazzling other road users, the height
of these headlamp beams must be adjusted
according to the load in the vehicle.

Guide-me-home lighting
Automatic
With the ring of the lighting control stalk in the
"AUTO" position and when the light is poor, the
sidelamps and dipped beam headlamps come
on automatically when the ignition is switched
off.
You can activate/deactivate this function
and adjust the guide-me-home lighting
duration in the Driving/Vehicle touch screen
menu.

Lighting and visibility
4To avoid damaging the wiper blades, do not operate the screenwash if the
screenwash reservoir is empty.
Only operate the screenwash if there is no
risk of the fluid freezing on the windscreen
and hindering visibility. During the winter
period, use "very cold climate" rated products.
Never top up with water.
Front intermittent wiping
In Intermittent mode, the driver can adjust the
wiping frequency by turning the ring to one of the
5 available positions.


The first (upper) position corresponds to the
longest time interval between 2 wipes for light
rain.
The last (lower) position corresponds to the
shortest time interval between 2 wipes
for heavy
rain.
A rotation of the ring from a higher position to a
lower position triggers a confirmation wiping.
After the ignition has been switched off for more than 1 minute with the wiper
control stalk in the INT, 1 or 2 position, when
the ignition is switched on again:
–

the system works as soon as the vehicle
exceeds 6 mph (10 km/h), if the outside
temperature is below +3°C.
–


the system works immediately
, if the
outside temperature is above +3°C.
Automatic windscreen wipers
In AUTO mode, the front wipers work
automatically and adapt to the intensity of
precipitation depending on the sensitivity of the
sensor selected.
The rainfall detection function uses a rain/
sunshine sensor located at the top centre of the
windscreen, behind the rear view mirror.
In certain weather conditions (e.g. fog,
frost, snow , projections on salty roads),
the driver may have to return to manual
wiping.
Switching on/off
To switch on:
► Put the wiper control stalk in the AUT
O
position.
►

T
urn the ring to adjust the sensitivity of the
sensor.
A wiping cycle, accompanied by the display of
a message, confirms that the request has been
taken into account.
►

T
o switch off, put the wiper control stalk in
another position or in the 0 position.
Adjusting the sensitivity

The first position (upper) corresponds to the
lowest sensitivity of the sensor.
The last position (lower) corresponds to the
highest sensitivity of the sensor.
The higher the sensitivity, the faster the system
reacts and increases the wiping frequency.
A rotation of the ring from a higher position to a
lower position triggers a confirmation wiping.
After the ignition has been switched off
for more than 1 minute with the wiper
control stalk in the AUTO position, when the
ignition is switched on again:
–

the system works, depending on the
volume of rain detected, as soon as the
vehicle exceeds 6 mph (10 km/h), if the
outside temperature is below +3°C.
–


the system works immediately
, depending
on the volume of rain detected, if the outside
temperature is above +3°C.

64
Lighting and visibility
Do not cover the rain/sunshine sensor.
When using an automatic car wash,
switch off the automatic wipers and the
ignition.
In winter, wait until the windscreen is
completely clear of ice before activating the
automatic wipers.
Malfunction
If a fault occurs with the automatic wipers, the
wipers operate in intermittent mode.
Have it checked by a CITROËN dealer or a
qualified workshop.
Special position of the
windscreen wipers
This maintenance position is used while cleaning
or replacing the wiper blades. It can also be
useful, in wintry weather (ice, snow), to release
the wiper blades from the windscreen.
To maintain the effectiveness of the flat wiper blades, it is advisable to:
–

handle them with care.
–


clean them regularly using soapy water
.
–

avoid using them to hold cardboard on the
windscreen.
–


replace them at the first signs of wear
.
Before removing a windscreen wiper blade

Operating the wiper control stalk immediately
after switching off the ignition will place the wiper
blades in a vertical position.
►

Safety
5Contact a CITROËN dealer or a qualified
workshop to have the system checked.
The airbags may not be deployed in the event of
a serious impact.
In the event of a minor impact or bump at
the side of the vehicle or if the vehicle
rolls over, the airbags may not be deployed.
In the event of a rear or front collision, none of
the lateral airbags are deployed.
Advice
For the airbags to be fully effective,
observe the safety recommendations
below.
Adopt a normal and upright sitting position.
Fasten your seat belt and position it correctly.
Do not place anything between the occupants
and the airbags (e.g.
child, animal, object), do
not fix or attach anything near or in the path of
the airbags, as this could cause injuries when
they are deployed.
Never modify the original definition of the
vehicle, particularly in the area directly around
the airbags.
Even if all of the precautions mentioned are
observed, a risk of injury or of minor burns to
the head, chest or arms cannot be ruled out
when an airbag is deployed. The bag inflates
almost instantly (within a few milliseconds)
then deflates within the same time,
discharging the hot gas via openings provided
for this purpose.
After an accident or if the vehicle has been
stolen, have the airbag systems checked.
All work must be carried out only by a
CITROËN dealer or a qualified workshop
Front airbags
Do not drive holding the steering wheel
by its spokes or resting your hands on the
centre part of the wheel.
Passengers must not place their feet on the
dashboard.
Do not smoke as deployment of the airbags
can cause burns or the risk of injury from a
cigarette or pipe.
Never remove or pierce the steering wheel or
hit it violently.
Do not fix or attach anything to the steering
wheel or dashboard, as this could cause
injuries when the airbags are deployed.
Lateral airbags
Use only approved seat covers
compatible with the deployment of these
airbags. For information on the range of seat
covers suitable for your vehicle, contact a
CITROËN dealer.
Do not fix or attach anything to the seat
backrests (e.g.
clothing) as this could cause
injuries to the chest or arm when the airbag is
deployed.
Do not sit with the upper part of the body any
nearer to the door than necessary.
The vehicle's front door panels include side
impact sensors.
A damaged door or any unauthorised or
incorrectly executed work (modification or
repair) on the front doors or their interior trim
could compromise the operation of these
sensors - risk of malfunction of the lateral
airbags!
All work must be carried out only by a
CITROËN dealer or a qualified workshop
Curtain airbags
Do not fix or attach anything to the roof,
as this could cause head injuries when the
curtain airbag is deployed.
Do not remove the grab handles installed on
the roof.
Child seats
The regulations on carrying children are specific to each country. Refer to the
legislation in force in your country.
For maximum safety, please observe the
following recommendations:
–

In accordance with European regulations,
all children under the age of 12 or less than
1,5 metres tall must travel in approved child

85
Driving
6Noise (Electric)
On the outside
Due to the vehicle’s quiet operation when
driving, the driver must pay particular attention.
When manoeuvring, the driver must always
check the vehicle's immediate surroundings.
At speeds of up to 19 mph (30 km/h), the
pedestrian horn warns other road users of the
vehicle’s presence.
Cooling the traction battery
The cooling fan comes on during
charging to cool the on-board charger and the
traction battery.
On the inside
During use, you may hear certain perfectly
normal noises specific to electric vehicles, such
as:
–

T
raction battery relay when starting.
–

V
acuum pump when braking.
–

V
ehicle tyres or aerodynamics when driving.
–

Jolting and knocking noise during hill starts.
Towing
Driving with a trailer places greater
demands on the towing vehicle and
particular care must be taken.
Do not exceed the maximum towable
weights.
At altitude: reduce the maximum load by
10% per 1,000 metres of altitude; the lower
air density at high altitudes decreases engine
performance.
New vehicle: do not tow a trailer until the
vehicle has driven at least 620 miles
(1,000 kilometres).
If the outside temperature is high, let the
engine idle for 1 to 2 minutes after the
vehicle comes to a stop, to help it to cool.
Before setting off
Nose weight
► Distribute the load in the trailer so that the
heaviest items are as close as possible to the
axle and the nose weight (at the point where it
joins your vehicle) approaches the maximum
permitted without exceeding it.
Tyres
► Check the tyre pressures of the towing
vehicle and of the trailer , observing the
recommended pressures.
Lighting
► Check the electrical signalling on the trailer
and the headlamp beam height of your vehicle.
If a genuine CITROËN towing device is
used, the rear parking sensors will be
deactivated automatically to avoid the audible
signal.
When driving
Cooling
Towing a trailer uphill causes the coolant
temperature to increase. The maximum towable
load depends on the gradient and the exterior
temperature. The fan’s cooling capacity does not
increase with engine speed.
►

Reduce speed and lower the engine speed to
limit the amount of heating produced.
►


Pay constant attention to the coolant
temperature.
If this warning lamp and the STOP
warning lamp come on, stop the
vehicle and switch off the engine as soon as
possible.
Brakes
Using the engine brake is recommended to limit
the overheating of the brakes. Braking distances
are increased when towing a trailer.
Side wind
Bear in mind that the vehicle will be more
susceptible to wind when towing.
