The rear screen demisting/defrosting can only
operate when the engine is running.
F
P
ress this button to demist /defrost the
rear screen and (depending on version)
the door mirrors. The indicator lamp
associated with the button comes on.
Switching off
The demisting/defrosting switches off
automatically to prevent an excessive
consumption of current.
F

I
t is possible to stop the demisting/
defrosting operation before it is switched
off automatically by pressing the button
again. The indicator lamp associated with
the button goes off. F
S witch off the demisting/defrosting
of the rear screen and door mirrors
as soon as appropriate, as lower
current consumption results in
reduced fuel consumption.

For optimum acceleration, for example
when overtaking another vehicle, press
the accelerator pedal firmly past the
point of resistance.
Temporary control of gear
changing
You can temporarily take over control of
gear changing using the "+" and "-" steering
mounted paddles: if the engine speed allows,
the request to change gear is acted on.
This function allows you to anticipate certain
situations such as overtaking a vehicle or the
approach to a corner.
After a few moments without any action on
the control paddles, the gearbox resumes
automatic control of the gears.
Manual mode
F Select position A .
Automated mode
AUTO and the gear engaged
appear in the instrument panel
screen.
The gearbox operates in auto-active mode,
without any action on the part of the driver. It
continuously selects the most suitable gear for:
-

o

ptimisation of fuel consumption,
-

t

he style of driving,
-

t

he profile of the road,
-

t

he vehicle load. F

Sel
ect position M.
The gears engaged appear in succession in the
instrument panel screen.
The gear change requests are
only acted on if the engine speed
permits. It is not necessary to release the accelerator
during gear changes.
When braking or slowing down, the gearbox
changes down automatically to allow the
vehicle to accelerate in the correct gear.
On sharp acceleration, the gearbox will not
change up unless the driver acts on the gear
lever or the steering mounted paddles.
Never select neutral N when driving. Never select neutral N while the vehicle
is moving. You can change mode at any time by
moving the gear selector from A to M or
the other way round.

Invalid value during manual
operation
This symbol is displayed if a gear
is not engaged correctly (selector
between two positions).
Stopping the vehicle
Before switching off the engine, you can
engage position P or N to place the gearbox in
neutral.
In both cases, apply the parking brake to
immobilise the vehicle, unless it is programmed
to automatic mode.If the lever is not in position P , when the
driver's door is opened or approximately
45 seconds after the ignition is switched
off, there is an audible signal and a
message appears.
F

R
eturn the lever to position P ;
the audible signal stops and the
message disappears.
Operating fault
When the ignition is on, the lighting of this
warning lamp, accompanied by an audible
signal and a message in the multifunction
screen, indicates a gearbox malfunction.
In this case, the gearbox switches to back-up
mode and is locked in 3rd gear. You may feel
a substantial knock when changing from P
to R and from N to R . This will not cause any
damage to the gearbox.
Do not exceed 60 mph (100 km/h), local speed
restrictions permitting.
Have it checked by a CITROËN dealer or a
qualified workshop.
This warning lamp may also come on if a door
is opened. You risk damaging the gearbox:
-

i
f you press the accelerator and
brake pedals at the same time,
-

i
f you force the lever from position
P

to another position when the
battery is flat.
To reduce fuel consumption when
stationary for long periods with the
engine running (traffic jam...), position
the gear lever at N and apply the
parking brake, unless it is programmed
in automatic mode.

Gear efficiency indicator*
On vehicle fitted with a manual
gearbox, the arrow may be
accompanied by the gear
recommended.
With an electronic or automatic
gearbox, the system is only active in
manual mode.
* Depending on engine.
On BlueHDi Diesel 150 versions with manual
gearbox, the system may suggest changing into
neutral so that the engine can go into standby
(STOP mode with Stop & Start), in certain
driving conditions. In this case, N is displayed
in the instrument panel. System which reduces fuel consumption by recommending the most appropriate gear.
Operation
Depending on the driving situation and your
vehicle's equipment, the system may advise
you to skip one (or more) gear(s). You can
follow this instruction without engaging the
intermediate gears.
The gear engagement recommendations must
not be considered compulsory. In fact, the
configuration of the road, the amount of traffic
and safety remain determining factors when
choosing the best gear. Therefore, the driver
remains responsible for deciding whether or not
to follow the advice given by the system.
This function cannot be deactivated. Example:
-

Y
ou are in third gear.
-

Y
ou press the accelerator pedal.
-

T
he system may suggest that you engage
a higher gear.
The information appears in the instrument
panel in the form of an arrow.
The system adapts its gear change
recommendation according to the
driving conditions (slope, load,
...) and
the demands of the driver (power,
acceleration, braking,
...).
The system never suggests:
-

e
ngaging first gear,
-
enga

ging reverse gear.
driving

Tyre under-inflation detection
System which automatically checks the
pressures of the tyres while driving.
The system continuously monitors the
pressures of the four tyres, as soon as the
vehicle is moving.
A pressure sensor is located in the valve of
each tyre (except the spare wheel).
The system triggers an alert if a drop in
pressure is detected in one or more tyres.Driving with under-inflated tyres
increases fuel consumption.The tyre pressures for your vehicle
can be found on the tyre pressure
label (see the "Identification markings"
section).
The tyre pressures must be checked
when the tyres cold (vehicle stopped
for 1 hour or after driving for less then
6 miles (10 km) at moderate speed).
Other wise, add 0.3 bar to the values
indicated on the label.
This system does not avoid the need
to check the tyre pressures regularly
(including the spare wheel) and before
a long journey.
Driving with under-inflated tyres
adversely affects road holding,
extends braking distances and causes
premature tyre wear, particularly under
arduous conditions (vehicle loaded,
high speed, long journey).
The tyre under-inflation detection system is an
aid to driving which does not replace the need
for vigilance on the part of the driver.

Stop & StartThe Stop & Start system puts the engine temporarily into standby - STOP mode - during stops in the traffic (red lights, traffic jams, or other...).
T he engine restarts automatically - START mode - as soon as you want to move off. The restart takes place instantly, quickly and silently.
Per fect for urban use, the Stop & Start system reduces fuel consumption and exhaust emissions as well as the noise level when stationary.
Operation
Going into engine STOP mode
With an electronic gearbox, for your
comfort during parking manoeuvres,
STOP mode is not available for a
few
seconds after coming out of
reverse gear.
STOP mode does not affect the
functionality of the vehicle, such as
braking, power steering, for example.
Never refuel with the engine in STOP
mode; you must switch off the ignition
with the key or the "START/STOP"
button.
The
"ECO" warning lamp comes on
in the instrument panel and the engine
goes into standby automatically:
-

w

ith a manual gearbox
, at speeds below
12 mph (20 km/h), or vehicle stationary with
PureTech 130 petrol and BlueHDi 115 and
120 Diesel versions, when you put the gear
lever into neutral and release the clutch
pedal,
-

w

ith an electronic gearbox , at a speed
below 5 mph (8 km/h), when you press
the brake pedal or place the gear lever in
position N .
-

w

ith an automatic gearbox, vehicle
stationary, when you press the brake pedal
or place the gear lever in position N .If your vehicle is fitted with the
system, a time counter calculates
the sum of the periods in STOP
mode during a journey. It resets
itself to zero every time the
ignition is switched on with the
key or the "START/STOP" button.
STOP mode is not invoked when:
-
t
he vehicle is on a steep slope (up or
d ow n),
-
t
he driver's door is open,
-
t
he driver's seat belt is not fastened,
- t he vehicle has not exceeded 6 mph
(10 km/h) since the last engine start (using
the key or the "START/STOP" button),
-

t
he electric parking brake is applied or
being applied,
-

t
he engine is needed to maintain a
comfortable temperature in the passenger
compartment,
-

d
emisting is active,
-

s
ome special conditions (battery charge,
engine temperature, braking assistance,
ambient temperature...) where the engine is
needed to assure control of a system.
Special cases: STOP mode
unavailable
In this case, the "ECO" warning lamp
flashes for a few seconds, then goes
of f.
This operation is perfectly normal.

Once the AdBlue® tank is empty,
a s
ystem required by regulations
prevents starting of the engine.
If the SCR

is faulty, the level of
emissions from your vehicle will no
longer meet the Euro 6 standard: you
vehicle becomes polluting.
In the event of a confirmed fault
with the SCR system, you must go
to a CITROËN dealer or a qualified
workshop as soon as possible: after a
running distance of 650 miles
(1 100 km), a system will be triggered
automatically to prevent engine
starting.
AdBlue® additive and SCR system
for BlueHDi Diesel engines
To assure respect for the environment and
conformity with the new Euro 6 emissions
standard, without adversely affecting the
per formance or fuel consumption of Diesel
engines, CITROËN has taken the decision to
equip its vehicles with an effective system that
associates SCR (Selective Catalytic Reduction)
with a particle filter (FAP) for the treatment of
exhaust gases.
Presentation of the SCR system
Using an additive called AdBlue® containing urea, a
catalytic converter turns up to 85% of nitrous oxides
(NOx) into nitrogen and water, which are harmless
to health and the environment.
The AdBlue® additive is held in a special
tank located under the boot at the rear of
the vehicle. It has a capacity of 17 litres: this
provides a driving range of about 12 500 miles
(20 000 km), after which an alert is triggered
warning you when the reserve remaining is
enough for just 1 500 miles (2 400 km).
During each scheduled service of your vehicle
by a CITROËN dealer or a qualified workshop,
the AdBlue
® additive tank is refilled in order to
allow normal operation of the SCR system.
If the estimated mileage between two services
is greater than 12 500 miles (20 000 km), we
recommend that you go to a CITROËN dealer
or a qualified workshop to have the necessary
top-up carried out.
