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.

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

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.

Particle filter (Diesel)
The start of saturation of the particle filter is
indicated by the temporary illumination of this
warning lamp, accompanied by a message in
the instrument panel screen.As soon as the traffic conditions permit,
regenerate the filter by driving at a
speed of at least 25 mph (40 km/h) for
about 20 minutes (with the 1.6 litre HDi
engine, the minimum speed is 37 mph
(60 km/h)).
If the warning lamp stays on, this
indicates a low additive level.
For more information on Checking
levels
and the Diesel additive level in
particular, refer to the corresponding
section.
On a new vehicle, the first particle
filter regeneration operations may be
accompanied by a "burning" smell,
which is per fectly normal.
Following prolonged operation of the
vehicle at very low speed or at idle,
you may, in exceptional circumstances,
notice the emission of water vapour at
the exhaust on acceleration. This does
not affect the behaviour of the vehicle
or the environment.
