These regular maintenance
operations will keep your vehicle
in good running order. Consult the
instructions at PEUGEOT dealerships,
on the Service Box site or in the
servicing booklet enclosed in the
handbook pack. To maintain the reliability of engines
and emission control systems, the use
of additives in engine oil is prohibited.
Oil change
It is imperative that this is carried out at
the intervals speciied and the viscosity
grade of the oil selected must fulil the
requirements in accordance with the
manufacturer’s servicing schedule.
Consult the instructions at PEUGEOT
dealerships or on the Service Box site.
Remove the dipstick before illing.
Check the level after illing (never
exceed the max mark).
Screw the cap back onto the sump
before closing the bonnet.
LEVELS
If you have to remove/reit the
engine style cover, handle it with
care to avoid damaging the ixing
clips.
Dipstick There are two marks
on the dipstick:
A = maximum
If you ill past this
mark, contact a
PEUGEOT dealer.
B = minimum
Never allow the level
to fall below this
mark. Warning lights
Oil level
Check the level regularly and top up
between changes. The maximum
consumption is 0.5 litre per 600 miles
(1 000 km).
Check the level with the vehicle level,
engine cold, using the dipstick.
Viscosity selection
In all cases, the oil selected must meet
the manufacturer’s requirements. Checking by means of the
warning lights on the instrument
panel is described in chapter 2,
"Instruments and controls" section.
Changing the brake fluid
The brake luid must be changed at
the intervals stated, according to the
manufacturer’s servicing schedule.
Use luids recommended by the
manufacturer, which fulil DOT4
standards.
The level must be between the MIN
and MAX marks on the reservoir.
If luid has to be added frequently,
this indicates a failure which must be
checked by a PEUGEOT dealer as
soon as possible.

Cooling system
Only use the luid recommended by the
manufacturer.
Otherwise, you risk seriously damaging
your engine.
When the engine is warm, the
temperature of the coolant is controlled
by the engine fan. As this fan can
operate with the ignition key removed
and because the cooling system is
pressurised, wait for at least one hour
after the engine has stopped before
carrying out any work.
Slacken the cap by 1/4 of a turn to
release the pressure to prevent any
risk of scalding. When the pressure
has dropped, remove the cap and top
up the level with coolant.
If luid has to be added frequently,
this indicates a failure which must be
checked by a PEUGEOT dealer as
soon as possible.Power steering fluid level
The vehicle must be parked on level
ground with the engine cold. Unscrew
the cap integrated with the gauge and
check the level which must be between
the MIN and MAX marks.
During regeneration of the particle
emission ilter, relay noise may be
heard under the fascia.
If the message is still displayed and
the service warning light remains on,
contact a PEUGEOT dealer.
Diesel additive level (Diesel with
particle emission filter) The minimum level of this
additive is indicated by
lighting of the service warning
light, accompanied by an
audible signal and a message
on the display.
When this occurs with the engine running,
this is due to the start of saturation of
the particle emission ilter (exceptionally
prolonged urban driving conditions: low
speed, long trafic jams, ...).
In order to regenerate the ilter, you
are advised to drive at a speed of
more than 40 mph (60 km/h) as soon
as possible, when trafic conditions
permit, for at least ive minutes (until
the message disappears and the
service warning light is switched off).
Topping up
The level must be between the MIN
and MAX marks on the expansion
bottle. If more than 1 litre of luid is
required to top up the level, have
the system checked by a PEUGEOT
dealer. Windscreen wash and headlamp
wash level
For best quality cleaning and for your
safety, we would advise that you use
products of the PEUGEOT Universal
range.
To avoid ice forming, do not use water.
Topping up
It is imperative that this additive is
topped up by a PEUGEOT dealer
without delay.
Used oil
Avoid prolonged contact of used oil
with the skin.
Brake luid is harmful to health and
very corrosive.
Do not dispose of used oil, brake
luid or coolant into drains or onto
the ground but into the containers
dedicated to this use at PEUGEOT
dealerships.

Levels
CHECKS
To check the main levels
and certain components,
in accordance with the
manufacturer’s servicing schedule,
refer to the pages of the servicing
booklet which correspond to your
vehicle’s engine.
Only use products recommended
by PEUGEOT or products
of equivalent quality and
characteristics.
In order to optimise the operation
of units as important as the braking
circuit, PEUGEOT selects and offers
speciic products.
In order to avoid damaging the
electrical units, high pressure washing
to clean the engine compartment is
strictly prohibited.
Oil filter
Change the ilter regularly, in
accordance with the servicing
schedule. Refer to the "Under the bonnet"
section of chapter 7.
Particle emission filter (Diesel)
It is imperative that particle emission
ilter maintenance is carried out by a
PEUGEOT dealer.
On acceleration after the vehicle has
been running for a prolonged period
at very low speed or at idle, you may,
in exceptional circumstances, notice
the emission of water vapour at the
exhaust. This water vapour does not
have any adverse effect on vehicle
handling or the environment.
Battery
At the start of winter, have your battery
checked by a PEUGEOT dealer.
Brake pads
Brake pad wear depends on the style
of driving, in particular for vehicles
which are used in town, over short
distances. It may be necessary to
check the thickness of the pads, even
between services.
Unless there is a leak on the circuit, a
drop in the brake luid level indicates
that the brake pads are worn.
Brake disc/drum wear status
For any information relating to
checking the brake disc/drum wear
status, contact a PEUGEOT dealer.
Handbrake
Where the handbrake travel is too
great or there is a reduction in the
performance of the system, the
handbrake should be adjusted, even
between services.
Have the system checked by a
PEUGEOT dealer.
Carbon filter and passenger
compartment filter
The carbon ilter permits continuous
and effective iltering of dust.
If the passenger compartment ilter
becomes clogged, this may reduce
the performance of the air conditioning
system and generate unpleasant odours.
We recommend the use of a combined
passenger compartment ilter. By
means of its second special active
ilter, it contributes to the puriication
of the air breathed by the occupants
and to the cleanness of the passenger
compartment (reduction of allergic
symptoms, unpleasant odours and
greasy deposits).
Refer to the servicing booklet to ind
out the replacement interval for these
components.
Depending on the environment (dusty
atmosphere...) and the use of the
vehicle (urban driving...), change them
twice as often if necessary.
Manual gearbox
Have the level checked in accordance
with the manufacturer’s servicing
schedule.
