In exceptional circumstances, the
gearbox may need an automatic
reinitialisation: starting and gear
changing are no longer possible.
Operating fault
With the ignition on, if this warning
lamp comes on and AUTO flashes,
accompanied by an audible signal
and a message in the multifunction
screen, this indicates a gearbox
fault.
Have it checked by a CITR

Automatic operation
F Select position D for automatic changing
of the four gears.
The gearbox then operates in auto-adaptive
mode, without any intervention on the part
of the driver. It continuously selects the most
suitable gear according to the style of driving,
the profile of the road and the load in the
vehicle.
For maximum acceleration without touching
the selector, press the accelerator pedal down
fully (kick down). The gearbox changes down
automatically or maintains the gear selected
until the maximum engine speed is reached.
On braking, the gearbox changes down
automatically to provide efficient engine
braking.
If you release the accelerator sharply, the
gearbox will not change to a higher gear for
safety reasons.

instrument panel.
If the engine speed is too low or too high, the

the actual gear engaged is displayed.
It is possible to change from position D
(automatic) to position M (manual) at any time.

very slowly, the gearbox selects gear M1
automatically.
The sport and snow programmes do not
operate in manual mode.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.
If the selector is not in position P ,
when the driver's door is opened or
approximately 45 seconds after the
ignition is switched off, a warning
message appears in the screen.

When driving on flooded roads or when
crossing a ford, proceed at walking
pace. 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 fault.
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.
Contact a CITR
oËn

dealer or a qualified
workshop as soon as possible.
Operating fault
There is a risk of damage to the gearbox:
- i f you press the accelerator and
brake pedals at the same time,
-
i

f you force the movement of the
selector from the P position to
another position when the battery
is
flat.
To reduce fuel consumption when at
a prolonged standstill with the engine
running (traffic jam...), put the selector
in the N position and apply the parking
brake.
Driving

131
Gear shift indicator*
In the case of driving which makes
particular demands on the performance
of the engine (firm pressure on the
accelerator pedal, for example, when
overtaking...), the system will not
recommend a gear change.
The system never suggests:
-
e
ngaging first gear,
-
enga

ging reverse gear,
-

e
ngaging a lower gear.
System which reduces fuel consumption by advising the driver to change up.
Operation
The system intervenes only when driving
economically.
dep

ending on the driving situation and your
vehicle's equipment, the system may advise
you to skip one or more gears. 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:
-

T
he system may suggest that you engage
a higher gear, if appropriate.
-
Y
ou are in third gear.
-
Y
ou press the accelerator pedal
moderately.

ending on engine.With an electronic or automatic
gearbox, the system is only active in
manual mode.
The information appears in the instrument
panel in the form of an arrow accompanied by
the suggested gear.

The Stop & Start system puts the engine temporarily into standby - STOP mode - during stops in the traffic (red lights, traffic jams, or other...). The
e ngine 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
- with a manual gearbox , at speeds below
12 mph (20 km/h), when you put the gear
lever into neutral, and you release the
clutch pedal.
-

w
ith a 5 or 6-speed electronic gearbox ,
when stationary or at speeds below 5 mph
(8 km/h) (depending on version), when
you press the brake pedal or put the gear
selector in position N .
Going into engine STOP
mode
The "ECO" warning lamp comes
on in the instrument panel and the
engine goes into standby:
a

time counter calculates the sum
of the periods in ST
oP m

ode
during a journey. It rests itself
to zero every time the ignition is
switched on with the key.
Special cases: STOP mode not
available
STOP mode is not invoked when:
- 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
t h e key,
-

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.
The "ECO" warning lamp flashes for
a few seconds then goes off.
This operation is perfectly normal.
Stop & Start
Never refuel with the engine in STOP
mode; you must switch off the ignition
with the key. For your comfort, during parking
manoeuvres, ST
oP m
ode is not
available for a few seconds after
coming out of reverse gear.
ST
oP m
ode does not affect the
functionality of the vehicle, such as for
example, braking, power steering...

133
Going into engine START
mode
The "ECO" warning lamp goes off
and the engine starts:
-

w

ith a manual gearbox , when you
depress the clutch pedal,
-

w

ith a 5-speed or 6-speed electronic
gearbox :
●

g

ear selector in position A or M , when
you release the brake pedal,
●

o

r gear selector in position N and the
brake pedal released, when you move
the gear selector to position A or M ,
●

o

r when you engage reverse gear.
Special cases: START invoked
automatically
For reasons of safety and for your comfort,
START mode is invoked automatically when:
-
y
ou open the driver's door,
-
y

ou unfasten the driver's seat belt,
-

t
he speed of the vehicle exceeds 7 mph
(11
km/h) with the electronic gearbox
system,
-

s
ome special conditions (battery charge,
engine temperature, braking assistance,
ambient temperature...) where the engine is
needed for control of a system.
Deactivation
at any time, press the "ECO OFF" switch to
deactivate the system.
This is confirmed by the switch warning lamp
coming on accompanied by a message in the
screen.
The "ECO" warning lamp flashes for
a few seconds, then goes off.
This operation is perfectly normal.
With a manual gearbox in STOP mode,
if you engage a gear without fully
depressing the clutch pedal, a message
is displayed asking you to fully depress
the clutch pedal so that the engine can
restart. If the system has been deactivated
in ST
oP m

ode, the engine restarts
immediately.

Hill start assist
System which holds your vehicle temporarily
(approximately 2 seconds) when starting on a
slope, the time it takes to move your foot from
the brake pedal to the accelerator pedal.
This function is only active when:
-
t
he vehicle is completely stationary, with
your foot on the brake pedal,
-

c
ertain conditions on a slope are met,
-

w
ith the driver’s door closed.
The hill start assist function cannot be
deactivated.
On an ascending slope, with the vehicle
stationary, the vehicle is held momentarily
when you release the brake pedal:
-

p
rovided you are in automated mode
(position A) or in manual mode (position M )
with an electronic gearbox.
Operating fault
If a malfunction of the system occurs, these
warning lamps come on. Contact a CITROËN
dealer or a qualified workshop to have the
system checked. On a descending slope, with the vehicle
stationary and reverse gear engaged, the
vehicle is held momentarily when you
release the brake pedal.
Do not leave the vehicle while it is being
held in the hill start assist phase.
If you need to leave the vehicle with
the engine running, manually apply
the parking brake then ensure that the
parking brake warning lamp is on (not
flashing) in the instrument panel.
