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.

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.

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.

CHECKS




















Screenwash and headlamp wash
fl uid

Fluid specifi cation
For optimum cleaning and to avoid
freezing, this fl uid must not be
topped up with or replaced with plain
water.











Diesel additive level (Diesel
engine with particle emission
filter)
A low additive level is indicated by
illumination of the service warning
lamp, accompanied by an audible
warning and a message in the multi-
function screen.

Topping up
This additive must be topped up by
a CITROËN dealer or a qualifi ed
workshop without delay.









Used products

Avoid prolonged contact of
used oil or fl uids with the
skin.
Most of these fl uids are harmful to
health or indeed very corrosive.
Do not discard used oil or
fl uids into sewers or onto
the ground.
Take used oil to a CITROËN
dealer or a qualifi ed workshop
(France) or to an authorised waste
disposal site.
In the case of vehicles fi tted
with headlamp washers, the
low fl uid level is indicated
by an audible signal and a
message in the screen.
Top up the reservoir when you next
stop the vehicle.









Coolant level

Changing the coolant
The coolant does not have to be
changed.

Fluid specifi cation
The coolant must conform to the
manufacturer's recommendations.

The coolant level should be
close to the "MAX" mark but
should never exceed it.
When the engine is warm,
the temperature of the coolant is
regulated by the fan. This can oper-
ate 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.
