Malfunction
When the ignition is on, the lighting
of this warning lamp, accompanied
by an audible signal and a message
in the screen, indicates a gearbox
fault.
In this case, the gearbox switches to back-up
mode and is locked in 3
rd 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 CITROËN dealer or a qualified
workshop as soon as possible.
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 position P to another
position when the battery is flat.
To reduce fuel consumption when at
a prolonged standstill with the engine
running (traffic jam, etc.), put the
selector in position N and apply the
parking brake. If your vehicle has an automatic gearbox,
never try to start the engine by pushing
the vehicle.
Gear efficiency indicator
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.
Gear shift recommendations should not be
considered obligatory. The configuration of the
road, the amount of traffic and safety remain
determining factors when choosing the best
gear. The driver thus remains responsible
for deciding whether to follow or ignore the
system's instructions.
This function cannot be deactivated.
With an automatic gearbox, the system is
only active in manual mode. On BlueHDi Diesel versions with manual
gearbox, in certain driving conditions the
system may suggest changing into neutral so
that the engine can go into standby (STOP
mode of Stop & Start). In this case, N is
displayed in the instrument panel.
Example:
-

Y
ou are in 3
rd g e a r.
-
Y
ou press the accelerator pedal.
-

T

he system may suggest that you engage a
higher gear.
The system adapts its gear change
recommendations according to the
driving conditions (slope, load, etc.)
and the demands of the driver (power,
acceleration, braking, etc.).
The system never suggests:
-
e

ngaging first gear,
-
enga

ging reverse gear,
-
enga

ging a lower gear.
The information appears in the instrument
panel in the form of an arrow.
Driving

129
On vehicles fitted with a manual gearbox,
the arrow may be accompanied by the
gear recommended.
Hill start assist
System which keeps your vehicle immobilised
temporarily (approximately 2 seconds) when
starting on a gradient, the time it takes to
move your foot from the brake pedal to the
accelerator pedal.
It is only active when:
-

t
he vehicle is completely stationary, with
your foot on the brake pedal,
-

c
ertain slope conditions are met,
-

t
he driver’s door is closed.Do not leave the vehicle while it is being
held temporarily in the hill start assist
phase.
If you need to leave the vehicle with the
engine running, apply the parking brake
manually then ensure that the parking
brake warning lamp lights up fixed on the
instrument panel. The hill start assist function cannot be
deactivated. However, use of the parking
brake to immobilise the vehicle interrupts
its operation.
On an ascending slope, with the vehicle
stationar y, the vehicle is held for a shor t
time when you release the brake pedal:
With a manual gearbox, if you are in first gear
or in neutral.
With an automatic gearbox, if you are in
position D or M . On a descending slope, with the vehicle
stationary and reverse gear engaged, the
vehicle is held for a shor t time when you
release the brake pedal.
Malfunction
If a fault in the system occurs, this warning
lamp comes on accompanied by a message.
Contact a CITROËN dealer or a qualified
workshop to have the system checked.
Stop & Start
The Stop & Start system puts the engine
t emporarily into standby – STOP mode – during
stops in traffic (red lights, traffic jams, etc.). The
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.

Stop & Star t time counter
(minutes/seconds or hours/minutes)
For your comfort, during parking
manoeuvres, STOP mode is not available
for a few seconds after coming out of
reverse gear.
The Stop & Start system does not affect
the functionality of the vehicle, such as for
example, braking, power steering, etc. Never refuel with the engine in STOP
mode; you must switch off the ignition with
the "START/STOP" button.
If your vehicle is fitted with this system, a time
counter calculates the sum of the periods in
STOP mode during a journey.
It resets to zero every time the ignition is
switched on.
