Deactivation

 Either by pressing on the brake
pedal or on the clutch pedal.

 Or by pressing button 3 .

 Or if either the ESP or the ASR
system is active.
The cruise control is not active if the
gear lever is in neutral.
These actions cause the information

"OFF" to appear on the instrument
panel screen.
These actions do not cancel the
cruise speed which remains dis-
played in the instrument panel.
Reactivation

 By recall of the memorised
speed
After a disengagement, press on button 3 . Your vehicle automati-
cally returns to the memorised
cruise speed which is displayed
in zone A .
If the memorised cruise speed is higher than the current speed,
the vehicle will accelerate to
reach the former.

 By selection of the current
speed
Press on button 2 or 4 once the
desired speed has been reached.
The information "OFF" will then
disappear from the instrument
panel display. Overriding the programmed
speed
During the operation of cruise con-
trol, it is always possible to use the
accelerator to go faster than the
cruise speed (for example to over-
take another vehicle). The speed
displayed in zone
A fl ashes.
You have only to release the accel-
erator pedal to return to the cruise
speed.
Return to normal driving

 By an action on the control 1 from
position "REG" to position 0 .

 By the engine stopping.
The cruise speed previously chosen is no longer memorised. Operating fault
If there is a malfunction, a message
will display accompanied by an au-
dible signal and lighting of the ser-
vice warning lamp.
Have it checked by a CITROËN
dealer.
If during the operation of cruise
control, the system is unable to
keep within the memorised speed
(for example on a steep descent),
then the speed fl ashes. Adapt your
speed as necessary. Cruise control should only be used
when the driving conditions allow
you to drive at a constant speed.
Do not use it in heavy traffi c, or on
dangerous or slippery roads.
The driver must remain attentive
and in full control of his vehicle.
You are recommended to keep your
feet within range of the pedals.
To avoid any risk of interfering with
the pedals:
- check that the fl oor mat is cor-
rectly positioned,
- never use more than one fl oor mat.

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 engine
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 al-
low the pressure to drop. When the
pressure 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.

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).
6-speed electronic gearbox
system 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 qual-
ity and specifi cations.
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
