DRIVING
Deactivation
Press on button 3
.
This action causes the
information "OFF"
to
appear on the instru-
ment panel screen.
This action does not cancel the
memorised maximum speed which
remains displayed in zone A
of the
instrument panel.
Override of the programmed
speed
The accelerator pedal is equipped
with an end-of-travel switch. If you
action this switch by pressing the
pedal hard down, you can exceed
the memorised maximum speed at
any time.
During the time the speed is be-
ing exceeded, the displayed speed
fl ashes.
You have only to release the ac-
celerator pedal to return below the
maximum speed and render the
function active again.
Return to normal driving
)
By moving the control 1
from po-
sition "LIM"
to position 0
.
)
By the engine stopping.
The speed previously chosen is still
memorised.
Operating fault
If there is a speed limiter malfunc-
tion, a message will display accom-
panied by an audible signal and
lighting of the service warning lamp.
Have it checked by a CITROËN
dealer or a qualifi ed workshop. If during the operation of the speed
limiter, the system is unable to keep
within the maximum speed (for ex-
ample on a steep descent or under
heavy acceleration) then the speed
fl ashes. Adapt your speed as neces-
sary.
The function will re-engage when
your speed returns below the de-
sired maximum speed.
On a steep downhill gradi-
ent or on sharp accelera-
tion, the speed limiter will
not be able to prevent the vehicle
from exceeding the programmed
speed.
Use of fl oor mats that are not ap-
proved by CITROËN may hinder
access to the accelerator pedal
and thus interfere with the function-
ing of the speed limiter.
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.

DRIVING
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. 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.
Return to normal driving
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 it checked by a CITROËN
dealer or a qualifi ed workshop.
Cruise control should only
be used when the driving
conditions allow you to drive
at a constant speed.
Do not use it in heavy traf-
fi c, or on dangerous or slippery
roads.
The driver must remain attentive
and in full control of his vehicle.
You are recommended to always
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.

Operation
You have identifi ed a parking
space:
)
Press button A
to activate the
function.
)
Activate the direction indicator
on the side where the space is to
be measured.
)
During the measuring, go for-
ward the length of the space, at
a speed less than 12 mph (ap-
proximately 20 km/h), to prepare
for your manoeuvre.
The system then measures the
size of the space.
)
The system informs you of the
level of diffi culty of the manoeu-
vre via a message in the multi-
function screen accompanied by
an audible signal.
Parking possible
Parking diffi cult
Parking not advised
The function displays the following
types of message: The function deactivates itself auto-
matically:
- when you engage reverse gear,
- when you switch off the ignition,
- fi ve minutes after activation of
the function or after the last mea-
surement operation,
- if the vehicle speed exceeds the
threshold of 45 mph (approxi-
mately 70 km/h) for one minute.
If there is a malfunction,
have the system checked
by a CITROËN dealer or a
qualifi ed workshop.
If the lateral distance between your
vehicle and the parking space is too
great, the system may not operate.
- The function remains available
after each measurement and so
can measure a number of places
successively.
- In bad weather or in winter, en-
sure that the sensors are not cov-
ered by dirt, or by ice or snow.
- The parking space sensor func-
tion deactivates the front parking
sensors during the space mea-
suring phase when you are in
forward gear.

CHECKING LEVELS
Oil level
Oil specifi cation
The oil must be the correct grade
for your engine and conform to the
manufacturer's recommendations.
Brake fl uid level
Changing the fl uid
Refer to the servicing booklet for de-
tails of the interval for this operation.
Fluid specifi cation
The brake fl uid must conform to the
manufacturer's recommendations
and meet the DOT4 standard.
The check is carried out ei-
ther when the ignition is
switched on using the oil lev-
el indicator on the instrument
panel, or using the dipstick.
This manual check will only be cor-
rect if the vehicle is on level ground
and the engine has been off for more
than 30 minutes.
It is normal to top up the oil lev-
el between two services (or oil
changes). CITROËN recommends
that you check the level, and top
up if necessary, every 3 000 miles
(5 000 kms). 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 re-
liability of the engine and
emission control system,
the use of additives in the engine
oil is prohibited.
Take care when working
under the bonnet, as cer-
tain areas of the engine
may be extremely hot (risk
of burns).
Power steering fl uid level
The power steering fl uid
level should be close to the
"MAX" mark. With the en-
gine cold, unscrew the cap
to check the level.
If a level drops signifi cantly, have
the corresponding system checked
by a CITROËN dealer or a qualifi ed
workshop.
Check all of these levels regularly
and top them up if necessary, unless
otherwise indicated.
Engine oil change
Refer to the servicing booklet for de-
tails of the interval for this operation. After topping up the oil, the check
when switching on the ignition with
the oil level indicator in the instru-
ment panel is not valid during the
30 minutes after topping up.
