Driving
With the engine running and the vehiclestationary, in order to immobilise the vehicleit is essential to manuallyapply the parking
brake by pulling
control lever A.


Immobilising the vehicle,
engine running


The emergency braking must only beused in exceptional circumstances.


Before leaving the vehicle, ensurethat parking brake warning lamp inthe instrument panel is on fixed, not flashing. The application of the parkin
g brake is confirmed by:
- illumination of the brakin
g
warning lamp and the Pwarning lamp in the control lever A ,
- displa
y of the message"Handbrake on".
When the driver’s door is opened, a messa
ge is
displa
yed accompanied by an audible signal, if
the parking brake has not been applied, except
in the case of an automatic gearbox with thegear lever in position P.P
Particular situations
In cer tain situations (e.g. star ting the engine),
the parking brake can automatically alter its force. This is normal operation.
To advance
your vehicle a few centimetres without star ting the engine, but with the ignition
on, press on the brake pedal and release the
parking brake by pulling
then releasing
the control lever A. The full release of the parkingbrake is confirmed by the warning lampsin the control lever A
and in the instrumentpanel going off and display of the message"Handbrake off".
If the parking brake develops a fault while appliedor if the battery runs flat, an
emergency release is always possible.



Emergency braking



In the event of failure of the electronicstability control system, signalled
by the illumination of this warning
lamp, braking stability is then not guaranteed.
In this event, stability must be assured by thedriver by repeating alternate "pull-release" actions on the control lever A.

In the event of a failure of the main servicebrake or in an exceptional situation (e.g. driver
taken ill, under instruction, etc) a continuous
pull on the control lever Awill stop the vehicle.
The electronic stability control provides stability
durin
g emergency braking.
If the emergency braking malfunctions,
the message "Parking brake faulty" will be
displayed.

Checks

























Checking levels
Check all of these levels regularly and top them up if necessary, unless other wise indicated.
If a level drops si
gnificantly, have the corresponding system checked by a CITROËN dealer or a qualified workshop.


Oil level
Engine oil change
Refer to the servicing booklet for the inter val
for this operation.
In order to maintain the reliabilit
y 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 engineand conform to the manufacturer'srecommendations.



Brake fluid level


Changing the fl uid

Refer to the servicing booklet for the inter valfor this operation.


Fluid specifi cation

The brake fluid must conform to themanufacturer's recommendations and meet
the DOT4 s t a n d a r d . Th
e brake fluid level should be closeto the "MA X" mark. If it is not, check
the brake pad wear.
The readin
g 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 theignition is switched on using the oil level
indicator in the instrument panel, or usingthe dipstick.
When working under the bonnet, take care, as cer tain areas of the engine may be extremely hot (risk of burns).
It is normal to top up the oil level
between two services. CITROËN recommends that you check the oillevel, and top up if necessary, every 3 000 miles (5 000 kilometres).

Par ticle emission filter (Diesel)
On a new vehicle, the first operations of regeneration of the par ticle emissions filter may be accompanied by the smell of "burning", w hic h is per fec t ly normal.Following prolonged operation of the vehicle at very low speed or at idle,you may, in exceptional circumstances,notice the emission of water vapour at the exhaust on acceleration. This doesnot affect the behaviour of the vehicleor the environment.
Manual gearbox

The gearbox does not require anymaintenance (no oil change).
Refer to the ser vicing booklet for the
details of the level checking interval for this component.
According to your version of instrument panel, the start of
saturation of the par ticle emissions filter is indicated by:

or a qualified workshop.


Manual parking brake
If a loss of effectiveness of this
system is noticed, the parking brake must be checked, even betweentwo services.
Checking this system must be done by aCITROËN dealer or a qualified workshop.
Brake pads
Brake wear depends on the styleof driving, par ticularly in the case of vehicles used in town, over shor t
distances. It may be necessary to have the condition of the brakes checked,even between vehicle services. Unless there is a leak in the system, a drop in
the brake fluid level indicates that the brake pads are worn.
