CHECKING LEVELS


Take care when working under
the bonnet, as certain areas of
the engine may be extremely hot
(risk of burns) and the cooling
fan could start at any time (even
with the ignition off).


The check is carried out either
when the ignition is switched
on using the oil level indicator
in the instrument panel, or us-
ing the dipstick.
It will only be correct 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 level be-
tween two services (or oil changes).
CITROËN recommends that you check
the level, and top up if necessary, every
3 000 miles (5 000 kms).
After topping up the oil, the check when
switching on the ignition with the oil
level indicator in the instrument panel
is not valid during the 30 minutes after
topping up.


















Oil level


Engine oil change
Refer to the maintenance and warranty
guide for details of the interval for this
operation.
In order to maintain the reliability of the
engine and emission control system,
the use of additives in the engine oil is
prohibited.











Brake fluid level


Changing the fl uid
Refer to the maintenance and warranty
guide for details of the interval for this
operation.

Fluid specifi cation
The brake fl uid must conform to the
manufacturer's recommendations.












Power steering fluid level

The power steering fl uid level
should be close to the "MAX"
mark. With the engine cold, un-
screw the cap to check the level.











Coolant level


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.
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, unscrew
the cap by two turns to allow the pres-
sure to drop. When the pressure has
dropped, remove the cap and top up
the level.

Fluid specifi cation
The coolant must conform to the manu-
facturer's recommendations.

Check all of these levels regularly, in
line with the maintenance and warranty
guide. Top them up if necessary, unless
otherwise indicated.
If a level drops signifi cantly, have the
corresponding system checked by a
CITROËN dealer or a qualifi ed work-
shop.

Oil specifi cation
The oil must be the correct grade for
your engine and conform to the manu-
facturer's recommendations.








The cooling fan may start after
switching off the engine: take
care with articles and clothing
that might become caught by the
fan blades.
The brake fl uid level should be
close to the "MAX" mark. If it is
not, check the brake pad wear.

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 corro-
sive.
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.









Additive level (Diesel with
particle emissions filter)
The additive reservoir low level is indi-
cated by:

Topping up
The reservoir must be topped up with-
out delay by a CITROËN dealer or a
qualifi ed workshop.


- fi xed illumination of the par-
ticle emissions fi lter warning
lamp, accompanied by an au-
dible signal and a message
that the particle emissions
fi lter additive level is too low.


Screenwash / headlamp wash
fluid level
Specifi cation of the fl uid
To ensure optimum cleaning and to
avoid freezing, the fl uid should never be
topped up or replaced by plain water.
In wintry conditions, the use of a fl uid
with an ethyl alcohol or methanol base
is recommended.
To check the level or top up
the fl uid on vehicle fi tted with
headlamp washers, immobilise
the vehicle and switch of the
engine.



Open the bonnet and secure it with
the stay.


Open the screenwash reservoir fi ll-
er cap.


Take and pinch the level gauge to
block its breather.


Remove the gauge completely from
the reservoir to read the level in the
transparent section.


Top up if necessary.


Refi t the fi ller cap to the reservoir
and close the bonnet.

CHECKS







Particle emission filter (Diesel)

The start of saturation of the particle
emissions fi lter is indicated by:


- fi xed illumination of the par-
ticle emissions fi lter warning
lamp, accompanied by an
audible signal and a message
that there is a risk of blockage
of the particle emissions fi lter.






The presence of this label, in particular
with the Stop & Start system, indicates
the use of a specifi c 12 V lead-acid bat-
tery with special technology and specifi -
cation. The involvement of a CITROËN
dealer or a qualifi ed workshop is essen-
tial when replacing or disconnecting the
battery. On a new vehicle, the fi rst op-
erations of regeneration of the
particle emissions fi lter may
be accompanied by the smell
of "burning", which is perfectly
normal.
Following prolonged operation
of the vehicle at very low speed
or at idle, you may, in excep-
tional circumstances, notice the
emission of water vapour at the
exhaust on acceleration. This
does not affect the behaviour of
the vehicle or the environment. As soon as the traffi c conditions per-
mit, regenerate the fi lter by driving at a
speed of at least 40 mph (60 km/h) until
the warning lamp goes off.
If the warning lamp stays on, refer to
the "Additive level" section.
Unless otherwise indicated, check
these components in accordance with
the maintenance and warranty guide
and according to your engine.
Otherwise, have them checked by a
CITROËN dealer or a qualifi ed work-
shop.





















Air filter and passenger compartment filter


Refer to the maintenance and
warranty guide for details of
the replacement intervals for
these components.
Depending on the environ-
ment (e.g. dusty atmosphere)
and the use of the vehicle
(e.g. city driving), replace
them twice as often if necessary
.
A clogged passenger compartment fi l-
ter may have an adverse effect on the
performance of the air conditioning sys-
tem and generate undesirable odours.















Oil filter

Replace the oil fi lter each time
the engine oil is changed.
Refer to the maintenance and
warranty guide for details of
the replacement interval for
this component.













12 V battery


The battery does not require
any maintenance.

However, check that the ter-
minals are clean and correctly
tightened, particularly in sum-
mer and winter.
When carrying out work on the battery,
refer to the "12 V battery" section for
details of the precautions to be taken
before disconnecting the battery and
following its reconnection.

When your vehicle's battery is dis-
charged, the engine can be started using
a slave battery (external or on another
vehicle) and jump lead cables.












Starting using another battery




12 V BATTERY

The battery is located under the bonnet.
For access to the (+) terminal:



release the bonnet using the interior
lever, then the exterior safety catch,


raise the bonnet and secure it with
its stay,


lift the plastic cover for access to the
(+) terminal.


Access to the battery







The presence of this label, in par-
ticular with the Stop & Start sys-
tem, indicates the use of a 12 V
lead-acid battery with special
technology and specifi cation;
the involvement of a CITROËN
dealer or a qualifi ed workshop is
essential when replacing or dis-
connecting the battery.
Procedure for starting the engine us-
ing another battery or charging a dis-
charged battery.

After refi tting the battery, the
Stop & Start system will only be
active after a continuous period
of immobilisation of the vehicle,
a period which depends on the
climatic conditions and the state
of charge of the battery (up to
about 8 hours).
First check that the slave battery
has a nominal voltage of 12 V
and a capacity at least equal to
that of the discharged battery.
Do not try to start the engine by
connecting a battery charger.
Do not disconnect the (+) termi-
nal when the engine is running.
Before doing any work
Immobilise the vehicle: apply the
parking brake, put the gearbox
in neutral, then switch off the ig-
nition.
Check that all electrical equip-
ment is switched off.

PRACTICAL INFORMATION
209









Charging the battery using a
battery charger
It is advisable to disconnect the
battery if the vehicle is to be left
unused for more than one month.












The batteries contain harmful
substances such as sulphuric
acid and lead. They must be
disposed of in accordance with
regulations and must not, in any
circumstances, be discarded
with household waste.
Take used remote control bat-
teries and vehicle batteries to a
special collection point.



Disconnect the battery from the vehicle.



Follow the instructions for use pro-
vided by the manufacturer of the
charger.


Connect the battery starting with the
negative terminal (-).


Check that the terminals and con-
nectors are clean. If they are covered
with sulphate (whitish or greenish
deposit), remove them and clean
them.

Protect your eyes and face be-
fore handling the battery.
All operations on the battery
must be carried out in a well
ventilated area and away from
naked fl ames and sources of
sparks, so as to avoid the risk of
explosion or fi re.
Do not try to charge a frozen
battery; the battery must fi rst
be thawed out to avoid the risk
of explosion. If the battery has
been frozen, before charging
have it checked by a CITROËN
dealer or a qualifi ed workshop
who will check that the inter-
nal components have not been
damaged and the casing is not
cracked, which could cause a
leak of toxic and corrosive acid.
Do not reverse the polarity and
use only a 12 V charger.
Do not disconnect the terminals
while the engine is running.
Do not charge the batteries with-
out disconnecting the terminals
fi rst.
Wash your hands afterwards.



Reinitialisation after
reconnection

After any reconnection of the battery,
switch on the ignition and wait at least
one minute before starting, to allow
time for the initialisation of the electron-
ic systems.
By referring to the corresponding sec-
tions, you should set or initialise the fol-
lowing systems yourself:


- one-touch electric windows,

- time and date,

- audio and navigation system set-
tings.
Check that no alert message or warn-
ing lamp comes on after switching on
the ignition.
However, if minor problems persist af-
ter carrying out these operations, con-
tact a CITROËN dealer or a qualifi ed
workshop.


Some functions are not available
if the battery is not suffi ciently
charged.









Do not push the vehicle to start
the engine if you have an elec-
tronic or automatic gearbox.
With Stop & Start, the battery
does not have to be disconnect-
ed for charging.

TOWING A TRAILER


We recommend the use of genu-
ine CITROËN towbars and their
harnesses that have been tested
and approved from the design
stage of your vehicle, and that
the fi tting of the towbar is en-
trusted to a CITROËN dealer or
a qualifi ed workshop.
If the towbar is not fi tted by a
CITROËN dealer, it is impera-
tive that it is fi tted in accordance
with the vehicle manufacturer's
instructions.
The rear parking sensors will
be deactivated automatically if
a genuine CITROËN towbar is
used.

Towbar suitable for the attachment of a
trailer or installation of a bicycle carrier,
with additional lighting and signalling.

Your vehicle is primarily designed for
transporting people and luggage, but it
may also be used for towing a trailer.
Driving with a trailer places greater de-
mands on the towing vehicle and the
driver must take particular care.



Driving advice


Distribution of loads



Distribute the load in the trailer so
that the heaviest items are as close
as possible to the axle and the nose
weight approaches the maximum
permitted without exceeding it.
Air density decreases with altitude, thus
reducing engine performance. Above
1 000 metres, the maximum towed load
must be reduced by 10 % for every
1 000 metres of altitude.

Side wind



Take into account the increased
sensitivity to side wind.


Cooling
Towing a trailer on a slope increases
the temperature of the coolant.
As the fan is electrically controlled, its
cooling capacity is not dependent on
the engine speed.



To lower the engine speed, reduce
your speed. The maximum towed load on a long in-
cline depends on the gradient and the
ambient temperature.
In all cases, keep a check on the cool-
ant temperature.



If the warning lamp and the
STOP
warning lamp come
on, stop the vehicle and
switch off the engine as
soon as possible.


Braking
Towing a trailer increases the braking
distance.
To avoid overheating of the brakes on a
long mountain type of descent, the use
of engine braking is recommended.

Tyres




Check the tyre pressures of the towing
vehicle and of the trailer, observing the
recommended pressures.



Lighting



Check the electrical lighting and sig-
nalling on the trailer.

Refer to the "Technical data" section for
details of the weights and towed loads
which apply to your vehicle.
