Electronic engine immobiliser
The keys contain an electronic chip which has
a secret code. When the ignition is switched
on, this code must be recognised in order for
starting to be possible.
This electronic engine immobiliser locks the
engine management system a few minutes
after the ignition is switched off and prevents
starting of the engine by anyone who does not
have the key.
In the event of a malfunction, you are informed
by a message in the instrument panel screen.
In this case, your vehicle does not start; contact
a CITROËN dealer as soon as possible.

Gear shift indicator*System which reduces fuel consumption by advising the driver to change gear on vehicles fitted with a manual gearbox.
Operation
* Depending on engine.-
f
or a change up,
In the case of driving which makes
particular demands on the per formance
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 engaging
reverse gear.
The system intervenes only when driving
economically.
Depending 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 recommendations should 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. A symbol appears in the instrument panel
when the system suggests changing to a more
suitable gear:
or
-
f
or a change down.
Driving

105
This gearbox has two driving modes:
- a n automated mode for automatic control
of the gears by the gearbox and therefore
without any action on the part of the driver,
-

a m
anual mode for sequential changing of
the gears by the driver using the steering
mounted controls or the gear lever.
CVT gearbox
It includes the following controls:
- a g ear lever 1 on the centre console
for selecting the driving mode, reverse
gear and neutral or for changing gear in
manual
m

ode, -
a "-"
steering mounted control paddle 2 for
manual downward gear changes,
-

a
"+/OFF" steering mounted control
paddle
3

for manual upward gear changes.
The six-speed automatic gearbox offers a choice between the comfort of automatic regulation or the pleasure of manual gear changing.
The mode can be changed at any time.

107
Stopping - Starting on a slope
It is essential to use the parking brake to
hold the vehicle on a slope and not the
accelerator pedal.
When starting on a slope, accelerate gradually
while releasing the parking brake.
Manual mode
F Select position +/-.
F U se the steering mounted controls or the
gear lever to change gear.
The gears engaged appear in succession in the
instrument panel screen.
The gear change instructions are only carried
out if the engine speed permits it.
You can change gear without taking your foot
off the accelerator pedal.
When decelerating, the gearbox changes down
automatically.
With the vehicle stationary, first gear is
engaged.
Automated mode
F Select position D .
"D" appears 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 gear most suited to
the conditions of:
-

d
riving style,
-

r
oad characteristics,
-

v
ehicle load.
To optimise driving comfort and obtain the most
suitable gear, avoid sharp variations in the
pressure on the accelerator pedal.
For the best acceleration, when
overtaking another vehicle, for example,
press firmly on the accelerator going
beyond the point of resistance.

Driving

108
Manual gear changing
In the automated mode, you can take over
control temporarily at any time using the
steering mounted controls.
The use of these controls permits manual
selection of the gears in situations which
require a faster change down than that offered
in automated mode (arrival at a roundabout,
exit from a car park with a steep gradient,
over taking...).
The gearbox engages the gear requested if
the engine speed permits it. The gear engaged
appears.
To return to the automated mode, do one of the
following:
-
p
ress the back of the "+/OFF" steering
mounted control 3 for approximately
2
seconds,
-

m
ove the gear lever quickly towards
position +/- and then return it to position D ,
-

s
top the vehicle.
Stopping the vehicle Operating fault
With the ignition on, if the message "Slow
down" or "Service required" appears in
the instrument panel screen, this indicates a
gearbox malfunction.
When a message is displayed, carry out the
following operations:
-

s
low down and stop your vehicle in a safe
place,
-

p
lace the lever in position P and let the
engine run,
-

o
pen the bonnet to allow the engine to
cool.
If the message disappears for a long period,
you can set off again.
If the message remains displayed or appears
frequently, contact a CITROËN dealer or a
qualified workshop without delay.
Before switching off the engine, you must place
the gear lever in position P
.
You must apply the parking brake to immobilise
the vehicle.

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.
This function is only active when:
-
t
he vehicle is completely stationary, with
your foot on the brake pedal,
-

w
hen certain conditions of gradient
are met,

stationar y, the vehicle is held for a brief
moment when you release the brake pedal:
-

i
f you are in first gear or neutral with a
manual gearbox,
-

i
f you are in position D with the CVT
gearbox.Operation
On a descending slope, with the vehicle
stationary and reverse gear engaged, the
vehicle is held for a brief moment 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 while
the engine is running, apply the parking
brake.
Operating fault
If a fault occurs with the system, this warning
lamp comes on, accompanied by a message
