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,
-

w
ith the driver’s door closed.
The hill start assist function cannot be
deactivated.
On an ascending slope, with the vehicle
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
in the instrument panel screen. Contact a
CITROËN dealer or a qualified workshop to
have the system checked.
When the engine is not running,
including periods on standby with
the Stop & Start (AS&G) system, the
function is not operative.

ith a manual gearbox , with the vehicle
stationary and your foot on the brake, when
you put the gear lever into neutral and
release the clutch pedal.
Never refuel with the engine in STOP
mode; you must switch off the ignition
with the key or the START/STOP
button. When the engine is stopped
automatically, the operation of certain
vehicle systems, such as for example,
braking, power steering... are modified.

warning lamp flashes, accompanied by
an audible signal.
The alert stops as soon as the gear
lever is returned to the neutral position.

Cruise control
System which automatically maintains the vehicle speed at the value programmed by the driver, without any action on the accelerator pedal.
The cruise control is switched on manually:
the vehicle speed must be at least 25 mph
(40 km/h) and second gear or higher must be
engaged in the case of a manual gearbox.
The cruise control is switched off manually, by
an action on the brake or clutch pedal or if the
ASC system is triggered.
The programmed speed can be exceeded
temporarily by pressing the accelerator pedal.
The cruise control cannot, in any
circumstances, take the place of the
need to comply with speed limits or of the
vigilance and responsibility of the driver. The controls of this system are grouped
together on the steering wheel.

Visual assistance
Front parking sensors
Deactivation / Activation of the
front and rear parking sensors
The function is deactivated by pressing this
button. The indicator lamp in the button
goes off.
Pressing this button again reactivates the
function. The indicator lamp in the button
comes on.
Operating fault
The front parking sensors are triggered when
an obstacle is detected in front, a gear is
engaged (position D for vehicles with a CVT
gearbox) and the speed of the vehicle remains
below 6 mph (10 km/h).
The front parking sensors are interrupted if
the vehicle stops for more than five seconds
in for ward gear, if no further obstacles are
detected or when the speed of the vehicle
exceeds 6 mph (10 km/h). Remember to deactivate the system if
towing a trailer or caravan.In bad weather or in winter, ensure that
the sensors are not covered with mud,
ice or snow.
When the vehicle is moving at a speed
below 6 mph (10 km/h), certain sound
sources (motorcycle, lorry, pneumatic
drill, etc.) may trigger the audible
signals of the parking sensor system.
In the event of an problem, when reverse gear
is engaged this lamp in the button flashes,
accompanied by an audible signal.
This supplements the audible
signal by displaying bars in the
screen, in front of or behind
the vehicle.
If one of the sensors is faulty, it
flashes in the instrument panel
screen.
Contact a CITROËN dealer or a qualified
workshop.
These bars flash at the start of the manoeuvre
then become fixed from a certain distance
between the vehicle and the obstacle.
