PARKING SPACE SENSORS


System which measures the parking
space available between two vehicles
or obstacles. It measures the size of the
space and gives you information on:


- the possibility of fi tting into a free
space, depending on the dimensions
of your vehicle and the distances
needed for manoeuvring,

- the level of diffi culty of the manoeuvre
to be performed.
The system does not measure spaces
which are clearly much smaller or larger
than the size of the vehicle.

Displays in the instrument panel



- on fi xed:
the function is selected by
a press on control A
.

- off:
the function is not selected,
The parking space sensor
function warning lamp can
have two different states:

Operation

You have identifi ed a parking space:


)
Press button A
to select the function.

)
Operate the direction indicator on
the side where the space is to be
measured; a message is displayed
to confi rm that measurement is in
progress.

)
During measurement, go forward
the length of the space, at a speed
less than 12 mph (approx. 20 km/h),
to prepare for your manoeuvre.

)
Once the measurement has been
completed, the system informs you
of the level of diffi culty of the ma-
noeuvre by a message in the multi-
function screen accompanied by an
audible signal.

The function displays the following types
of message:

Parking possible


Parking diffi cult


Parking not advised

The function deselects itself automati-
cally:


- when you engage reverse gear,

- when you switch off the ignition,

- if measuring is not requested,

- within fi ve minutes of selection of
the function,

- if the vehicle speed exceeds the
threshold of 45 mph (approx. 70 km/h)
for one minute.

If the lateral distance between your ve-
hicle and the parking space is too large,
the system may not be able to measure
the space.
If there is a fault, have the sys-
tem checked by a CITROËN
dealer or a qualifi ed workshop.

The system remains available after
each measurement and can therefore
measure several spaces in succession.
In poor or wintry weather, ensure that
the sensors are free of dirt, ice or snow.
The parking space sensor system de-
activates the front parking sensors
when measuring forwards.

PARKING SENSORS

This system indicates the proximity of an
obstacle (person, vehicle, tree, gate, etc.)
which comes within the fi eld of detection
of sensors located in the bumper.
Certain types of obstacle (stake, road-
works cone, etc.) detected initially will
no longer be detected at the end of the
manoeuvre due to the presence of blind
spots.

This function cannot, in any cir-
cumstances, take the place of
the vigilance and responsibility
of the driver.
The system is switched on by engaging
reverse gear. This is accompanied by
an audible signal.
The system is switched off when you
exit reverse gear.

Rear parking sensors


Audible assistance
The proximity information is given by an
intermittent audible signal, the frequen-
cy of which increases as the vehicle ap-
proaches the obstacle.
The sound emitted by the speaker (right
or left) indicates the side on which the
obstacle is located.
When the distance between the vehicle
and the obstacle becomes less than
approximately thirty centimetres, the
audible signal becomes continuous.


Visual assistance
This supplements the audible signal
by displaying bars in the multifunction
screen which move progressively near-
er to the vehicle. When the obstacle is
near, the "Danger" symbol is also dis-
played in the screen.

DRIVING

In addition to the rear parking sensors,
the front parking sensors are triggered
when an obstacle is detected in front
and the speed of the vehicle is still below
6 mph (10 km/h).
The front parking sensors are interrupted
if the vehicle stops for more than three
seconds in forward gear, if no further ob-
stacles are detected or when the speed
of the vehicle exceeds 6 mph (10 km/h).






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 comes on.
Pressing this button again reactivates
the function. The indicator lamp in the
button goes off.


Operating fault



The function will be deactivated
automatically if a trailer is being
towed or a bicycle carrier is fi t-
ted (vehicle fi tted with a towbar
or bicycle carrier recommended
by CITROËN).

In bad weather or in winter, en-
sure that the sensors are not
covered with mud, ice or snow.
When reverse gear is engaged,
an audible signal (long beep) in-
dicates that the sensors may be
dirty.
When the vehicle is moving at a
speed below 6 mph (10 km/h),
certain sound sources (motor-
cycle, lorry, pneumatic drill, etc.)
may trigger the audible signals
of the parking sensor system.
In the event of a malfunction
of the system, when reverse
gear is engaged this warn-
ing lamp is displayed in the instrument
panel and/or a message appears in the
screen, accompanied by an audible
signal (short beep).
Contact a CITROËN dealer or a qualifi ed
workshop.

The sound emitted by the speaker (front
or rear) indicates whether the obstacle
is in front or behind.

CHECKING LEVELS

Check all of these levels regularly and
top them up if necessary, unless other-
wise indicated.
If a level drops signifi cantly, have the
corresponding system checked by a
CITROËN dealer or a qualifi ed work-
shop.

When working under the bonnet,
take care, as certain areas of the
engine may be extremely hot (risk
of burns).
The reading will only be correct if
the vehicle is on level ground and
the engine has been off for more
than 30 minutes.
The check is carried out either when the
ignition is switched on using the oil level
indicator in the instrument panel, or using
the dipstick.
It is normal to top up the oil level between
two services. CITROËN recommends that
you check the oil level, and top up if neces-
sary, every 3 000 miles (5 000 kilometres).

Oil level


Engine oil change
Refer to the servicing booklet for the
interval for this operation.
In order to maintain the reliability of the
engine and emission control system,
the use of additives in the engine oil is
prohibited.
Oil specifi cation
The oil must correspond to your engine
and conform to the manufacturer's
recommendations.



Brake fluid level

The brake fl uid level should be
close to the "MAX" mark. If it is
not, check the brake pad wear.

Changing the fl uid
Refer to the servicing booklet for the
interval for this operation.

Fluid specifi cation
The brake fl uid must conform to the
manufacturer's recommendations and
meet the DOT4 standard.



Power steering fluid level

The power steering fl uid level
should be close to the "MAX"
mark. Unscrew the cap, with
the engine cold, to check the
level.


Coolant level

The coolant level should be
close to the "MAX" mark but
should never exceed it.
When the engine is warm, the
temperature of the coolant is regulated
by the fan. This can operate with the ig-
nition off.

On vehicles which are fi tted with a par-
ticle emission fi lter, the fan may oper-
ate after the vehicle has been switched
off, even if the engine is cold.
In addition, as the cooling system is
pressurised, wait at least one hour after
switching off the engine before carrying
out any work.
To avoid any risk of scalding, unscrew
the cap by two turns to allow the pres-
sure to drop. When the pressure has
dropped, remove the cap and top up
the level.

Changing the coolant

The coolant does not have to be changed.


Coolant specifi cation
The coolant must conform to the manu-
facturer's recommendations.
