Driving
Stop & Start
The Stop & Start function puts the engine temporarily into standby - STOP mode - during
phases when the vehicle is stopped (red lights,
queues, etc.). The engine restarts automatically
- START mode - as soon as the driver wishes to
move off again.
Primarily designed for urban use, the function
is intended to reduce fuel consumption and
exhaust emissions as well as the noise level
when stationary.
The function does not affect the functionalities of
the vehicle, in particular the braking.
Deactivation/Reactivation
The function is activated by default when the
ignition is switched on.
It is set via the Driving / Vehicle touch
screen menu.
A message in the instrument panel confirms the
change of status.
When the function is deactivated, if the engine
was in standby, it restarts immediately.
Associated indicator lamp
Function activated.
Opening the bonnet
Before doing anything under the bonnet,
deactivate the Stop & Start system to avoid
The system triggers an alert as soon as it
detects a drop in the inflation pressure of one or
more tyres.
Under-inflation detection does not
replace the need for vigilance on the part
of the driver.
This system does not avoid the need to
regularly check the tyre pressures (including
the spare wheel) as well as before a long
journey.
Driving with under-inflated tyres, particularly
in adverse conditions (heavy load, high
speed, long journey):
–

worsens road-holding.
–


lengthens braking distances.
–


causes premature wear of the tyres.
–


increases fuel consumption.
The inflation pressures defined for the vehicle can be found on the tyre pressure
label.
For more information on the Identification
markings, refer to the corresponding section.
Checking tyre pressures
This check should be done when the
tyres are "cold" (vehicle stopped for 1 hour or
after a journey of less than 6 miles (10
km) at
moderate speeds).
Otherwise, add 0.3 bar to the pressures
shown on the label.
Snow chains
The system does not have to be
reinitialised after fitting or removing snow
chains.
Spare wheel
The steel spare wheel does not have an
under-inflation detection sensor.
Under-inflation alert
This is signalled by the fixed illumination of this warning lamp, accompanied by an
audible signal and the display of a message.
►

Reduce speed immediately
, avoid excessive
steering movements and avoid sudden braking.
►

Stop the vehicle as soon as it is safe to do
so.
The loss of pressure detected does not always cause visible bulging of the tyre.
Do not rely on just a visual check.
►

Using a compressor
, such as the one in
the temporary puncture repair kit, check the
pressures of the four tyres when cold.
►

If it is not possible to make this check
immediately

, drive carefully at reduced speed.
►

In the event of a puncture, use the
temporary puncture repair kit or the spare wheel
(depending on equipment).
The alert is kept active until the system is reinitialised.
Reinitialisation
Reinitialise the system after adjusting one or
more tyre pressures and after changing one or
more wheels.


Before reinitialising the system, make
sure that the pressures of the four tyres
are correct for the conditions of use of the
vehicle and conform to the values written on
the tyre pressure label.
Check the pressures of the four tyres before
performing the reinitialisation.
The system does not advise if a pressure is
incorrect at the time of reinitialisation.
With the vehicle stationary, the system is
reinitialised via the Driving /
V
ehicle touch screen menu.
Malfunction
These warning lamps come on in the event of a malfunction.
In this case, the tyre under-inflation monitoring
function is no longer performed.
Have the system checked by a CITROËN dealer
or a qualified workshop.

Practical information
7Recommendations
► 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.
►


Lash the load down securely and fit a
warning flag if it overhangs the vehicle.
►


Drive gently: the vehicle will be more
susceptible to the effects of side winds
(stability may be affected).
►


Remove the roof bars once they are no
longer needed.
Maximum load, distributed over the roof
bars, for a loading height not exceeding
40 cm: 80 kg.
As this value may change, please verify the
maximum load quoted on the note 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
mountings on the vehicle.
Be sure to refer to national legislation in order
to comply with the regulations for transporting
objects which are longer than the vehicle.
Bonnet
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.
The location of the interior bonnet release lever prevents opening the
bonnet when the left-hand front door is
closed.
When the engine is hot, handle the
exterior safety catch and the bonnet stay
with care (risk of burns), using the protected
area.
When the bonnet is open, take care not to
damage the safety catch.
Do not open the bonnet under very windy
conditions.
Cooling of the engine when stopped
The engine cooling fan may start after
the engine has been switched off.
Take care with objects or clothing that
could be caught in the blades of the fan!
Opening



► Open the left-hand front door .
► Pull the interior release lever , located at the
bottom of the door frame, towards you.

Practical information
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.


► Unclip the stay from its housing and place it
in the support slot to hold the bonnet open.
Closing
► Hold the bonnet and pull out the stay from the
support slot.
►

Clip the stay in its housing.
►


Lower the bonnet and release it near the end
of its travel.
►


Pull on the bonnet to check that it is locked
correctly

.
Because of the presence of electrical
equipment under the bonnet, it is strongly
recommended that exposure to water (rain,
washing, etc.) be limited.

only by a CITROËN dealer or a qualified
workshop.
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).

In the event of a breakdown
8After changing a wheel
Store the punctured wheel in the boot or,
depending on version, remove the central cover
first to store it beneath the floor in place of the
spare wheel.


With a "space-saver" type spare wheel
Deactivate certain driving aid functions
(Active Safety Brake, etc.).
Do not exceed the maximum authorised
speed of 50 mph (80
km/h).
Driving with more than one “space-saver”
type spare wheel is prohibited.
Visit a CITROËN dealer or a qualified
workshop as soon as possible to have
the tightness of the bolts and the pressure of
the spare wheel checked.
Have the punctured tyre examined. After
inspection, the technician will advise you on
whether the tyre can be repaired or if it must
be replaced.
Changing a bulb
In some weather conditions (e.g. low
temperature or humidity), misting on the
internal surface of the glass of the headlamps
and rear lamps is normal, and will disappear
after the lamps have been on for a few
minutes.
The headlamps have polycarbonate lenses with a protective coating:
–

Do not clean them with a dry or abrasive
cloth, nor with detergent or solvent
products.
–


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 headlamps, 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 headlamp /
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
of the same type and specification. To avoid
lighting imbalance, replace the bulbs in pairs.
Opening the bonnet / Accessing the
bulbs
With the engine warm, proceed with caution -
risk of burns!
Take care with objects or clothing that could
be caught in the blades of the cooling fan -
risk of strangulation!
Halogen bulbs (Hx)
To ensure good quality lighting, check
that the bulb is correctly positioned in its
housing.
After changing a bulb
To refit, carry out the fitting operations in
reverse order.
Close the protective cover very carefully to
guarantee the sealing of the lamps.
