HILL START ASSIST
System which keeps your vehicle
immobilised temporarily (approxi-
mately 2 seconds) when starting on
a gradient, the time to move your
foot from the brake pedal to the ac-
celerator pedal.
This function is only active when:
- the vehicle is completely station-ary, with your foot on the brake
pedal,
- in certain conditions on a gradient,
- with the driver’s door closed.
The hill start assist function cannot
be deactivated. Operation

On an ascending gradient, with
the vehicle stationary, the vehicle
is held for a brief moment when
you release the brake pedal:
- provided you are in fi rst gear or neutral on a manual gearbox,
- provided you are in D or M on an
automatic gearbox.
On a descending gradient, with
the vehicle stationary and reverse
gear engaged, the vehicle is held
for a brief moment when you re-
lease the brake pedal.
Do not exit the vehicle while
it is being held in the hill start
assist phase.
If you need to leave the ve-
hicle with the engine running, ap-
ply the parking brake manually
and ensure that the parking brake
warning lamp (in the instrument
panel) is on fi xed (not fl ashing).

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.
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 manufac-
turer'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 regular-
ly. Fluid which has been used exces-
sively may cause a loss of braking
effi ciency.
Fluid specifi cation
The brake fl uid must conform to the
manufacturer's recommendations
and meet the DOT4 standard.
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.
Take care when doing anything un-
der the bonnet, as some parts of the
engine can be extremely hot (risk of
burns). The brake fl uid level should
be close to the "MAX" mark.
If it is not, check the brake
pad wear.
In order to maintain the reli-
ability of the engine and emis-
sion control system, the use
of additives in the engine oil is
prohibited. Power steering fluid or power
steering and suspension
fluid level
This fl uid must be topped up
by a CITROËN dealer.
Dipstick
There are 2 marks on the
dipstick:
-
A = max; never exceed
this level,
- B = min; top up the
level via the oil fi ller
cap, using the type
of oil suited to your
engine.

Brake pads Brake wear depends on
the style of driving, par-
ticularly in the case of ve-
hicles used in town, over
short distances. It may be
necessary to have the condition of
the brakes checked, even between
vehicle services.
Unless there is a leak in the circuit, a
drop in the brake fl uid level indicates
that the brake pads are worn.

Manual gearbox
The gearbox does not re-
quire any maintenance (no
oil change).

Automatic gearbox
The gearbox does not re-
quire any maintenance (no
oil change). Brake disc wear
For information relating to
checking the brake disc
wear, contact a CITROËN
dealer.
Parking brake If a loss of effectiveness
of this system is noticed,
the parking brake must be
checked, even between
two services.
This system must be checked by a
CITROËN dealer. Only use products recom-
mended by CITROËN or
products of equivalent quality
and specifi cations.
Do not use a dry cloth with an abra-
sive product for the maintenance of
aluminium parts; use a sponge and
soapy water.
In order to optimise the operation
of units as important as the braking
system, CITROËN selects and of-
fers very specifi c products.
To avoid damaging the electrical
units, the use of a high pressure
washer in the engine compartment
is strictly prohibited .

Warranty Guide for the details of the
level checking interval for this com-
ponent.
