AUDIBLE AND/OR VISUAL REAR PARKING ASSISTANCE
System consisting of four proximity
sensors, located in the rear bumper.
This detects any obstacle (person,
vehicle, tree, gate, etc.) behind the
vehicle, except obstacles located
just below the bumper.
An object, such as a stake, a road-
works cone or any other similar ob-
ject may be detected at the begin-
ning of the manoeuvre, but may no
longer be detected when the vehicle
comes close to it.
If there is an operating fault, when reverse gear is en-gaged this warning lamp comes on in the instrument panel, accompanied by an audible signal (short beep) and a message on the multifunction screen.
In bad or wintry weather, ensure that the sensors are not covered with mud, frost or snow.
Programming
You can activate or deactivate the system by means of the multifunc-tion screen confi guration menu. The system state is memorised when switching off the ignition.
For more information on access to the parking assistance menu, refer to the section on vehicle confi guration for your screen under "Multifunction screens".
The system will be deactivated auto-matically when towing a trailer or when a bicycle carrier is fi tted (vehi-cle fi tted with a towbar or bicycle car-rier recommended by CITROËN). cle fi tted with a towbar or bicycle car-cle fi tted with a towbar or bicycle car-
The parking assistance system cannot, in any circumstances, take the place of the vigilance and res-ponsibility of the driver.
Activation
The system is activated as soon as reverse gear is engaged, accompa-nied by an audible signal. The proxi-mity information is given by:
- an audible signal, which beco-mes more rapid as the vehicle approaches the obstacle,
- a graphic on the multifunction screen, with blocks which be-come increasingly closer to the vehicle.
When the distance between the rear of the vehicle and the obstacle is less than thirty centimetres, the audible signal becomes continuous and the "Danger" symbol appears on the multifunction screen.
On completion of the manoeuvre, when you exit reverse gear, the system becomes inactive.

CHECKING LEVELS
Check all of these levels regularly
and top them up if necessary, unless
otherwise indicated.
If a level drops signifi cantly, have the
corresponding system checked by a
CITROËN dealer.
Take care when working under the
bonnet, as some parts of the engine
can be extremely hot (risk of burns).
Oil level
Oil change
Refer to the Maintenance and
Warranty Guide for details of the in-
terval for this operation. Oil specifi cation The oil must correspond to your en-gine and conform to the manufacturer's
recommendations.
Brake fluid level
Fluid change
Refer to the Maintenance and
Warranty Guide for details of the in-
terval for this operation.
This fl uid must be changed regu-
larly. Fluid which has been used for
too long may cause a loss of braking
effi ciency.
Fluid specifi cation
The brake fl uid must conform to the
manufacturer's recommendations
and fulfi l the DOT4 standards.
Coolant level
Coolant change
The coolant does not have to be
changed.
Fluid specifi cation
The coolant must conform to the
manufacturer's recommendations.
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 using the dipstick.
Check this level also between each
scheduled service and before long
journeys. The brake fl uid level should
be close to the "MAX" mark.
If it is not, check the brake
pad wear.
The coolant level should be
close to the "MAX" mark but
should never exceed it.
When the engine is warm, the tem-
perature 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 en-
gine 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, un-
screw the cap by two turns to allow
the pressure to drop. When the pres-
sure has dropped, remove the cap
and top up the level.
In order to maintain the re-
liability of the engine and
emission control system,
the use of additives in the engine
oil is prohibited.
