DRIVING
PARKING SENSORS
System comprising four proximity sen-
sors, located in the rear bumper.
This detects any obstacle (person, vehi-
cle, tree, gate, etc.) behind the vehicle.
Nevertheless, it cannot detect obstacles
located just below the bumper. An object, such as a stake, a road-
works cone or any other similar
object may be detected at the be-
ginning of the manoeuvre, but may
no longer be detected when the ve-
hicle comes close to it. Activation
The system is activated as soon as re-
verse gear is engaged, accompanied
by an audible signal. The proximity in-
formation is given by:
- an audible signal, which becomes
more rapid as the vehicle approaches
the obstacle,
- a graphic on the multifunction screen, with blocks which become
increasingly closer to the vehicle. The parking sensors system can-
not, in any circumstances, take the
place of the vigilance and responsi-
bility of the driver.
Detection zone
When the distance between the rear of
the vehicle and the obstacle is less than
thirty centimetres, the audible signal be-
comes continuous and the "Danger" sym-
bol appears on the multifunction screen.
On completion of the manoeuvre, when
you exit reverse gear, the system be-
comes inactive.

DRIVING
Deactivation
The system will be deactivated au-
tomatically when towing a trailer
or when a bicycle carrier is fi tted
(vehicle fi tted with a towbar or bi-
cycle carrier recommended by
CITROËN). Reactivation
Press button
A again to reactivate the
system. The indicator lamp on the but-
ton is switched off.
If there is an operating fault, when re-
verse gear is engaged, the service
warning lamp comes on, accompanied
by an audible signal (short beep) and a
message on the multifunction screen.
With the engine running, press button A to
deactivate the system permanently. The
indicator lamp on the button comes on. In bad or wintry weather, ensure
that the sensors are not covered
with mud, frost or snow.

CHECKS
BONNET

 Push the exterior safety catch B to
the left and raise the bonnet.
 Unclip the stay C from its housing.

 Fix the stay in the notch to hold the
bonnet open.
Closing

 Take the stay out of the support
notch.

 Clip the stay in its housing.

 Lower the bonnet and release it at
the end of its travel.

 Pull on the bonnet to check that it is
secured correctly.

 Open the front left door.

 Pull the interior bonnet release lever A ,
located at the bottom of the door
frame. The location of the interior bonnet
release lever prevents opening of
the bonnet while the front left door
is closed.
When the engine is hot, handle the
exterior safety catch and the bon-
net stay with care (risk of burns).
Opening
RUNNING OUT OF FUEL (DIESEL)
If your vehicle is fi tted with an HDI en-
gine, the fuel system must be primed if
you run out of fuel.
This system consists of a priming pump,
a transparent pipe and a bleed screw
under the bonnet.
HDi 90 and HDi 110 FAP engines

 Fill the fuel tank with at least fi ve litres
of Diesel.

 Open the bonnet.

 Depending on version, unclip the
cover to gain access to the priming
pump.

 Squeeze and release the prim-
ing pump until fuel appears in the
transparent pipe with the green
connector.

 Operate the starter until the engine
starts.

 Depending on version, put the cover
back in position and clip it in place.

 Close the bonnet.
If the engine does not start at the
fi rst attempt, do not try again.
Operate the priming pump again,
then the starter.

CHECKING LEVELS Brake fluid level
Oil level The reading will only be correct
if the vehicle is on level ground
and the engine has been off for
more than 15 minutes.
The check is carried out either when the
ignition is switched on using the oil level
indicator on the instrument panel, or us-
ing the dipstick. 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 Maintenance and Warranty
Guide for details of the interval for this
operation.
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
ignition off.

On vehicles which are fi tted with a
particle emission fi lter, the fan may
operate 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. Fluid specifi cation
For optimum cleaning and to avoid
freezing, this fl uid must not be topped
up or replaced with water.
Engine oil change
Refer to the Maintenance and Warranty
Guide for details of 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 grade
The oil must be suitable for your engine
and conform to the manufacturer's recom-
mendations. Fluid specifi cation
The brake fl uid must conform to the
manufacturer's recommendations and
meet the DOT4 standard.
Fluid specifi cation
The coolant must conform to the manu-
facturer's recommendations.
Changing the coolant
The coolant does not have to be
changed.
Screenwash fluid level
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.
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.
Top up the level when neces-
sary.
Take care when carrying out checks under the bonnet as some parts of
the engine can be very hot (risk of
burns).

CHECKS
Avoid prolonged contact of used oil
or fl uids with the skin.
Most of these fl uids are harmful to
health or indeed very corrosive.
Do not discard used oil or fl uids
into sewers or onto the ground.
Take used oil to a CITROËN dealer
(France) or an authorised waste
disposal site.
Diesel additive level (Diesel
engine with particle emission
filter)
A low additive level is indicated by light-
ing of the service warning lamp, accom-
panied by an audible warning and a
message on the multifunction screen.

CHECKS
Battery
The battery does not require
any maintenance.
However, check that the ter-
minals are clean and correctly
tightened, particularly in sum-
mer and winter.
When carrying out work on the battery,
refer to the "Practical information" sec-
tion for details of the precautions to be
taken before disconnecting the battery
and following its reconnection.
Air filter and passenger compartment filter
Refer to the Maintenance and
Warranty Guide for details of
the replacement intervals for
these components.
Depending on the environment
(e.g. dusty atmosphere) and the use of
the vehicle (e.g. city driving), replace
them twice as often if necessary (refer
to the "Engines" paragraph).
A clogged passenger compartment fi lter
may have an adverse effect on the per-
formance of the air conditioning system
and generate undesirable odours. Particle emission filter (Diesel)
It is imperative that the maintenance of
the particle emission fi lter is carried out
by a CITROËN dealer.
Oil filter
Replace the oil fi lter each time
the engine oil is changed.
Refer to the Maintenance and
Warranty Guide for details of
the replacement interval for
this component.
Following prolonged operation of
the vehicle at very low speed or at
idle, you may, in exceptional cir-
cumstances, notice the emission
of water vapour at the exhaust on
acceleration. This does not affect
the behaviour of the vehicle or the
environment.
Topping up
This additive must be topped up by a
CITROËN dealer without delay.
Unless otherwise indicated, check
these components in accordance with
the Maintenance and Waranty Guide
and according to your engine.
Otherwise, have them checked by a
CITROËN dealer.
