Driving
6The system adapts its gear shift recommendation according to the driving
conditions (slope, load, etc.) and the driver’s
requirements (request for power, acceleration,
braking, etc.).
The system never suggests:
–

engaging first gear
.
–

engaging a lower gear
.
–

engaging reverse.
With a manual gearbox, the arrow may
be accompanied by the recommended
gear. The system always suggests changing
to a higher gear when this is necessary.
Hill start assist
This system keeps your vehicle briefly stationary
(for approximately 2 seconds) when making a hill
start, while you transfer your foot from the brake
pedal to the accelerator pedal.
This system is only active when:
–

the vehicle is completely stationary
, with your
foot on the brake pedal,
–

certain slope conditions are met,
–


the driver
’s door is closed.
Do not leave the vehicle while it is being
held temporarily by hill start assist.
If someone needs to get out of the vehicle
with the engine running, apply the parking
brake manually. After that, ensure that the
parking brake indicator lamp and the indicator
lamp P in the electric parking brake control
lever are on fixed.
The hill start assist function cannot be deactivated. However, use of the parking
brake to immobilise the vehicle interrupts its
operation.
Operation

Facing uphill, with the vehicle stationary,
the vehicle is held for a short time when you
release the brake pedal:
–

provided you are in first gear or neutral with a
manual gearbox.
–


provided you are in mode D

or M with an
automatic gearbox.


Facing downhill, with the vehicle stationary
and reverse gear engaged, the vehicle is held
for a short time when you release the brake
pedal.
Malfunction
This warning lamp comes on in the event of a malfunction, accompanied by an
onscreen message.
Contact a CITROËN dealer or a qualified
workshop to have the system checked.
Tyre under-inflation detection
This system automatically checks the pressures
of the tyres while driving.
It compares the information given by the wheel
speed sensors with reference values, which
must be reinitialised every time the tyre
pressures are adjusted or a wheel changed.

76
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.

After the engine has restarted, STOP mode is not available until the vehicle
has reached a speed of 5 mph (8
km/h).

88
Driving
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.
Lane Departure Warning
System
Refer to the General recommendations on the
use of driving and manoeuvring aids .
This system, using a camera which recognises
solid or broken lines, detects the involuntary
crossing of longitudinal traffic lane markings on
the ground.
If the driver's attention drops and the speed
is higher than 37 mph (60 km/h), the system
triggers a warning if there is an unexpected
change of direction.
This system is particularly useful on motorways
and main roads.


Deactivation of the system is signalled by
the illumination of this warning lamp,
accompanied by the display of a message.
Malfunction
In the event of a fault with the system, you
are alerted by the fixed illumination of this
warning lamp, accompanied by the display of a
message and an audible signal.
Contact a CITROËN dealer or a qualified
workshop to have the system checked.
Distraction detection
Refer to the General recommendations on the
use of driving and manoeuvring aids .
Take a break in case of feeling tired or at least
every 2 hours.
The function consists of the "Coffee Break Alert"
system combined with the "Driver Attention
Warning" system.
These systems are in no way designed to keep the driver awake or to prevent
the driver from falling asleep at the wheel.
It is the driver’s responsibility to stop if feeling
tired.
Activation / Deactivation
It is set via the Driving / Vehicle touch
screen menu.
The state of the system stays in the memory
when the ignition is switched off.
Coffee Break Alert
The system triggers an alert as soon as it detects that the driver has not taken a
break after two hours of driving at a speed above
40 mph (65
km/h).
This alert is issued via the display of a message
encouraging the driver to take a break,
accompanied by an audible signal.
If the driver does not follow this advice, the alert
is repeated hourly until the vehicle is stopped.
The system resets itself if one of the following
conditions is met:
–

With the engine running, the vehicle has been
stationary for more than 15 minutes.
–


The ignition has been switched off for a few
minutes.
–


The driver's seat belt is unfastened and their
door is opened.
As soon as the speed of the vehicle drops below 40 mph (65 km/h), the
system goes into standby.
The driving time is counted again once the
speed is above 40 mph (65
km/h).
Driver Attention Warning

Using a camera placed at the top of the
windscreen, the system assesses the
driver's level of vigilance, fatigue or distraction by
identifying variations in trajectory compared to
the lane markings.
This system is particularly suited to fast roads
(speed higher than 40 mph (65
km/h)).
At a first-level alert, the driver is warned by the
“Take care! ” message, 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.

Practical information
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.
► 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
systemI windscreen wipers, dipped beam
headlamps, courtesy lamps, etc. for a maximum
combined duration of about forty minutesK
Switching to the mode
A message indicating that the vehicle has
switched to economy mode is displayed on the
touch screen and the active functions are put on
standby.
If a telephone call is in progress at the
time, it will be maintained for around 10
minutes using your audio system’s hands-free
system.
Exiting the mode
These functions will be automatically restored
the next time the vehicle is used.
In order to restore the use of these functions
immediately, start the engine and let it run:
–

for less than ten minutes, to use the
equipment for approximately five minutes,
–


for more than ten minutes, to use the
equipment for up to approximately thirty minutes.
Let the engine run for the duration specified to
ensure that the battery charge is sufficient.
Do not repeatedly and continuously restart the
engine in order to charge the battery

.
A flat battery prevents the engine from starting.
For more information on the 12 V battery,
refer to the corresponding section.
Roof bars
For safety reasons and to avoid
damaging the roof, it is essential to use
the transverse bars approved for your vehicle.
Observe the fitting instructions and the
conditions of use in the guide supplied
with the roof bars.
Version without longitudinal
bars


When fitting roof bars, use only the four fixing
points located in the roof frame. The points are
hidden by the vehicle doors when closed.


The roof bar fixings include a lug to be fitted into
the hole at each fixing point.
Version with longitudinal
bars


You must fit the transverse bars to the
longitudinal bars at the fixing points indicated by
engraved markings on the longitudinal bars.

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.

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.

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 saturation of the particle filter
is signalled by the temporary illumination
of this warning lamp, accompanied by a
message warning of the risk of the filter clogging
up.
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.
If the warning lamp stays on, this
indicates a low Diesel additive level.
For more information on Checking levels,
refer to the corresponding section.
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.
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.
Screenwash fluid
Top up to the required level when necessary.
Fluid specification
The fluid must be topped up with a ready-to-use
mixture.
In winter (temperatures below zero), a liquid
containing an agent to prevent freezing must
be used which is appropriate for the prevailing
conditions, in order to protect the elements of the
system (pump, tank, ducts, jets, etc.).
Filling with pure water is prohibited under
all circumstances (risk of freezing,
limestone deposits, etc.).
Diesel fuel additive (Diesel
with particle filter)
On reaching the minimum level in the
particle filter additive tank, this warning
lamp comes on fixed, accompanied by an
audible warning and a message warning that the
additive level is too low.
Topping up
This additive must be topped up without delay by
a CITROËN dealer or a qualified workshop.
AdBlue (BlueHDi)
An alert is triggered when the reserve level is
reached.
For more information on the AdBlue range
indicators, refer to the corresponding section.
To avoid the vehicle being immobilised in
accordance with regulations, you must top up the
AdBlue tank.
For more information on the Supply of AdBlue,
refer to the corresponding section.
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.
However, 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.

Following prolonged operation of the
vehicle at very low speed or at idle, you
may, in exceptional circumstances, notice the
emission of water vapour at the exhaust on
acceleration. This does not affect the
behaviour of the vehicle or the environment.
New vehicle
The first particle filter regeneration
operations may be accompanied by a
"burning" smell, which is perfectly normal.
Manual gearbox
The gearbox does not require any maintenance (no oil change).
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/drum wear
For any information on checking brake
disc/drum wear, contact a CITROËN
dealer or a qualified workshop.
Parking brake
If excessive travel or a loss of
effectiveness of this system is noticed, the
parking brake must be checked, even between
two services.
This system must be checked by a CITROËN
dealer or a qualified workshop.
Wheels and tyres
The pressure must be checked on all tyres, including the spare wheel, when the
tyres are "cold".
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.
Driving with under-inflated tyres
increases fuel consumption. Non-
compliant tyre pressure causes premature
wear on tyres and has an adverse effect on
