river.
Reactivation
Press this button again.
Operating fault
Have it checked by a CITROËN dealer or a qualified w orkshop.
In
the event of a fault in STOP mode, the vehicle
m
ay stall.
All
of the instrument panel warning lamps come on.
Depending
on version, an alert message may also
b
e displayed, asking you to place the gear selector
l
ever on position N
and put your foot on the brake
ped
al.
It
is then necessary to switch off the ignition and
s
tart the engine again using the "START/STOP"
b
utton. In

f
lashes for a few moments then
c
omes on continuously.
The

is
active
again;
this
is

The
Stop & Start system makes use of
a
dvanced technology. For any work on
t
he system go to a qualified workshop
w
ith the skills and equipment required,
w
hich a CITROËN dealer is able to
pro
vide.
Before
doing anything under the
b
onnet, deactivate the Stop & Start
s
ystem to avoid any risk of injury
r
esulting from automatic operation of
S
TART mode.
Maintenance
This system requires a 12 V battery with a special specification and technology (reference
n
umbers available from CITROËN dealers).
Fitting
a battery not listed by CITROËN
i
ntroduces the risk of malfunction of the
s
ystem.
For
charging, use a 12 V charger and do not
r
everse the polarity.

active cruise control
This systems allows, in addition to maintaining your vehicle's speed at a value that you have defined, the inter-vehicle time you have selected between your vehicle and the one ahead to be
m
aintained.Principles of operation
Using a radar with a range of about 100 metres, located at the front of the vehicle, this system
d
etects a vehicle running in front of your
v
ehicle.
It
automatically adapts the speed of the vehicle
t
o that of the vehicle in front.
If
the vehicle in front is running more slowly,
t
he system progressively reduces the speed of
y
our vehicle using just engine braking (as if the
d
river had pressed the "-"
button).
If
your vehicle is too close to or approaching
t
oo quickly the vehicle in front, the cruise
c
ontrol is automatically deactivated. The
d
river is then alerted by an audible signal,
a
ccompanied by a message.
If
the vehicle in front accelerates or changes
l
ane, the active cruise control progressively
a
ccelerates your vehicle to return to the
programmed
s
peed.
If
the driver operates a direction indicator to
t
he left (left hand drive) or the right (right hand
d
rive), to overtake a slower vehicle, the active
c
ruise control allows your vehicle to temporarily
a
pproach the vehicle in front to assist the
overtaking
ma
noeuvre,
t
hough
n
ever
e
xceeding
t
he programmed speed.
Choice of the type of cruise control
If you want to use the standard cruise control, it is possible to deactivate the active cruise
control
in the the touch screen tablet.
F
I
n the "Driving assistance "
menu,
press this button; its
i
ndicator lamp goes off.
The
standard cruise control is available.Refer to the previous section for the
details
of the operation of the standard
c
ruise control.
This
is confirmed by the display of
t
his symbol in the control. You can return to the active
cruise
control
at any time by pressing this
bu
tton
ag
ain.
F
P
lace the cruise control thumb
w
heel at "CRUISE".

The active cruise control is switched on
manually: it requires that the speed of the vehicle b
e between 25 mph (40 km/h) and 90 mph
(
150 km/h), as well as the engagement of:
-
f
ourth gear or higher with a manual
g
earbox,
-
s
econd gear or higher with an electronic or
a
utomatic gearbox in manual mode,
-
p
osition A with an electronic gearbox or D
with
an automatic gearbox.
General points
The active cruise control can above be paused
using the control, or automatically:
-
b
y pressing the brake or clutch pedal,
-
i
n the event of operation of the ESC, for
s
afety reasons,
-
i
n the event of operation of the electric
p
arking brake control lever,
-
w
hen an inter-vehicle time threshold is
r
eached (calculated according to the
r
elative speeds of your vehicle and the
v
ehicle in front and the inter-vehicle time
se
tting
c
hosen),
-
w
hen the distance between your vehicle
a
nd the one in front becomes to small,
-
w
hen the speed of the vehicle in front is to
l
ow,
-
w
hen the speed of your vehicle becomes
t
oo low.
The active cruise control cannot in any
circumstances
replace
the
observation
o
f
speed
limits,
nor
the
need
for
v
igilance
on
the
part
of
the
driver.
It
i
s
r
ecommended
that
y
ou
a
lways
k
eep
y
our
feet
close
to
the
pedals.
If
the
speed
setting
selected
is
above
9
3
mph
(150
km/h),
the
system
switches
t
o
standard
cruise
control
operation
(
a
message
appears
in
the
instrument
pan
el). The
inter-vehicle time setting is
m
emorised on switching off the ignition.
The active cruise control operates by
day
and
at
night,
in
fog
or
in
moderate
r
ainfall.
The system does not act on the braking s ystem, but works only with engine braking.
The
regulation range is limited: there will
n
o longer be any adjustment of speed if the
d
ifference between the programmed speed
s
etting and the speed of the vehicle in front
b
ecomes too high (18 mph (30 km/h)).
The selection of this system deactivates the inter-vehicle time function.
If
the difference between the
p
rogrammed speed setting and the
s
peed of the vehicle in front is too
g
reat, the speed cannot be adjusted:
t
he cruise control is automatically
d
eactivated.

etection of a vehicle that is too close or running at a speed lower than your

The
system uses engine braking to slow your vehicle and then hold it at the speed of
t

The
regulation range is limited to a maximum difference of 20 mph (30 km/h)
b
etween the speed setting and the speed of the vehicle ahead.

The active cruise control uses only engine braking to slow the vehicle. Consequently the
v
ehicle looses speed slowly, as when releasing
t
he accelerator pedal.
The
system is paused automatically:
-
i
f the vehicle in front slows down to much
o
r too suddenly, and the driver does not
b
rake,
-
i
f a vehicle comes between your vehicle
a
nd the vehicle in front,
-
i
f the system does not slow the vehicle
e
nough to continue to maintain a safe
d
istance, for example when descending a
s
teep hill.
Limits of operation
As the radar's field of view is quite narrow, it is possible that the system may not detect:
The
cruise control does not take account of:
-
s
tationary vehicles,
-
v
ehicles driving in the opposite direction.
-
v
ehicles of reduced width, such as
m
otorcycles, for example,
-
v
ehicles not running in the middle of the

Park Assist
This system provides active assistance with parking, detecting a parking space then
c
ontrolling the steering to park in the space.
It
controls the steering while the driver
m
anages the accelerator, brakes, gears and
c
lutch (manual gearbox). During phases of
e
ntry into and exit from a parking space, the
s
ystem provides visual and audible information
t
o the driver in order to make the manoeuvres
s
afe. It may be necessary to move for wards
a
nd backwards more than once. During
a manoeuvre the steering wheel
t
urns quickly: do not hold the steering
w
heel, do not place your hand between
t
he spokes of the steering wheel and
t
ake care with loose and bulky clothing,
s
carves, handbags... There is a risk of
in
jury.
When
Park Assist is activated, it
p
revents a change to STOP mode of
S
top & Start. In STOP mode, activation
o
f Park Assist restarts the engine.
The
Park Assist system cannot in any
c
ircumstances replace the need for
v
igilance on the part of the driver.
The
driver must remain in control
o
f their vehicle ensuring that the
s
pace remains clear throughout the
m
anoeuvre.
In
some circumstances, the sensors
m
ay not detect small obstacles located
i
n their blind spots.
The
driver can take control at any time by
g
ripping the steering wheel. The
Park Assist system provides assistance for t
he following manoeuvres:
