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.

Automatic gearbox
The gearbox does not require
any maintenance (no oil change).
Refer to the maintenance and
warranty guide for details of
the level checking interval for
this component.
















Electric parking brake

This system does not require
any routine servicing. However,
in the event of a problem,
have the system checked by
a CITROËN dealer or a qualifi ed work-
shop.





















Manual parking brake

















Only use products recommended
by CITROËN or products of equiva-
lent quality and specifi cation.

In order to optimise the opera-
tion of units as important as
those in the braking system,
CITROËN selects and offers
very specifi c products.
After washing the vehicle, damp-
ness, or in wintry conditions, ice
can form on the brake discs and
pads: braking effi ciency may be
reduced. Make light brake ap-
plications to dry and defrost the
brakes.
If a loss of effectiveness of this
system is noticed, the parking
brake must be checked, even
between two services.
Checking this system must be
done by a CITROËN dealer or a quali-
fi ed workshop.
















Brake pads

Brake wear depends on the
style of driving, particularly in
the case of vehicles 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.


Brake disc wear

For information on checking
brake disc wear, contact a
CITROËN dealer or a quali-
fi ed workshop.
For more information, refer to the "Electric
parking brake - Operating faults" section.








Manual gearbox

The gearbox does not re-
quire any maintenance (no oil
change).
Refer to the maintenance and
warranty guide for the details
of the level checking interval
for this component.







Electronic gearbox

The gearbox does not require
any maintenance (no oil change).
Refer to the maintenance and
warranty guide for details of the
checking interval for this compo-
nent.

SNOW CHAINS


In wintry conditions, snow chains improve traction as well as the behaviour of the vehicle when braking.

Advice on installation



If you have to fi t the chains during
a journey, stop the vehicle on a fl at
surface on the side of the road.


Apply the parking brake and posi-
tion any wheel chocks to prevent
movement of your vehicle.


Fit the chains following the instruc-
tions provided by the manufacturer.


Move off gently and drive for a
few moments, without exceeding
30 mph (50 km/h).


Stop your vehicle and check that
the snow chains are correctly tight-
ened.

The snow chains must be fi tted
only to the front wheels. They
must never be fi tted to "space-
saver" type spare wheels.

Take account of the legislation in
force in your country on the use
of snow chains and the maxi-
mum running speed authorised.
Avoid driving on roads that
have been cleared of snow, to
avoid damaging your vehicle's
tyres and the road surface. It is
recommended that before you
leave, you practise fi tting the
snow chains on a level and dry
surface. If your vehicle is fi tted
with alloy wheels, check that no
part of the chain or its fi xings is
in contact with the wheel rim.


Use only the chains designed to be fi t-
ted to the type of wheel fi tted to your
vehicle:
Original tyre size Maximum link
size.
195/65 R15
9 mm
205/55 R16
225/45 R17
225/40 R18

cannot be fi tted with chains

For more information on snow chains,
contact a CITROËN dealer or a quali-
fi ed workshop.

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.
