Blind spot sensors
This driving assistance system warns the driver
of the presence of another vehicle in the blind
spot angle of their vehicle (areas masked from
the driver's field of vision), as soon as this
presents a potential danger.
Operation
This system is designed to improve safety when driving and is in no circumstances a
substitute for the use of the interior rear view mirror and door mirrors. It is the driver's
responsibility to constantly check the traffic, to assess the distances and relative speeds of
other vehicles and to predict their movements before deciding whether to change lane.
The blind spot sensor system can never replace the need for vigilance on the part of
the
d
river. F
O
n switching on the ignition, or engine
running, press this button to activate the
function; the warning lamp comes on.
Sensors fitted in the front and rear bumpers
monitor the blind spots.
A warning lamp appears in the door mirror on
the side in question:
-
i
mmediately, when being overtaken,
-
a
fter a delay of about one second, when
overtaking a vehicle slowly.

Operating fault
In the event of a fault, the warning lamp in the
button flashes then goes off.
Have it checked by a CITROËN dealer or a
qualified workshop.The system may suffer temporary
interference in certain weather
conditions (rain, hail...).
In particular, driving on a wet sur face
or moving from a dry area to a wet area
can cause false alerts (for example, the
presence of a fog of water droplets in
the blind spot angle is interpreted as a
vehicle).
In bad or wintry weather, ensure that
the sensors are not covered by mud,
ice or snow.
Take care not to cover the warning
zone in the door mirrors or the
detection zones on the front and rear
bumpers with adhesive labels or other
objects; they may hamper the correct
operation of the system.
F
T
o deactivate the system, press this button
again; the warning lamp goes off.
The state of the system remains in memory on
switching off the ignition.
The system is automatically
deactivated when towing with a towbar
approved by CITROËN.

System which automatically maintains the cruising speed of the vehicle at a setting programmed by the driver, without any action on the accelerator
pedal.
The cruise control is switched on
manually.
It requires a minimum vehicle speed of
25 mph (40 km/h) as well as:
-
w
ith a manual gearbox, the
engagement of fourth gear or
higher,
-
w
ith an automatic gearbox, the
gear selector at position
d or
second gear or higher in manual
mode.
As a safety measure, you are advised
to keep your feet near the pedals at all
times.
Switching off the ignition cancels any
programmed speed setting.
The cruise control system is a driving aid
that cannot, in any circumstances, replace
the need to observe speed limits, nor the
need for vigilance on the part of the driver.
The operation of the cruise control can be
interrupted (pause):
-

brake or clutch pedal,
-
a

Removing a wheel
Parking the vehicle
Immobilise the vehicle where it does
not block traffic: the ground must be
level, stable and non-slippery ground.
Apply the parking brake unless it has
been programmed to automatic mode,
switch off the ignition and engage first
gear* to lock the wheels.
Check that the braking warning lamps
in the instrument panel are on (not
flashing).
The occupants must get out of the
vehicle and wait where they are safe.
If necessary, place a chock under the
wheel diagonally opposite the wheel to
be changed.

Installing electrical
accessories
Your vehicle's electrical system is
designed to operate with standard or
optional equipment.
Before installing other electrical
equipment or accessories on your
vehicle, contact a CITROËN dealer or a
qualified workshop.
CITROËN will not accept responsibility
for the cost incurred in repairing your
vehicle or for rectifying malfunctions
resulting from the installation of
accessories not supplied and not
recommended by CITROËN and
not installed in accordance with its
instructions, in particular when the
combined consumption of all of the
additional equipment connected
exceeds 10 milliamperes.
Before changing a fuse:
F
t
he cause of the failure must be identified
and rectified,
F
all electrical consumers must be switched off,F the vehicle must be immobilised with the
ignition off,
F
i
dentify the failed fuse using the tables and
layout drawings in the following pages.
Changing a fuse
Good Failed
The replacement of a fuse not shown in
the tables below may cause a serious
malfunction of your vehicle. Contact
a CITROËN dealer or a qualified
workshop. Tw e e z e r
To replace a fuse, you must:
F
u
se the special tweezer to extract the fuse
from its housing and check the condition of
its filament.
F
a
lways replace the failed fuse with a fuse
of the same rating (same colour); using a
different rating could cause faults (risk of
f i r e).
If the fuse fails again soon after replacement,
have the vehicle's electrical system checked by
a CITROËN dealer or a qualified workshop.
