Levels These regular maintenance
operations will keep your vehicle
in good running order. Consult the
instructions at PEUGEOT dealerships
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 specifi ed and the viscosity
grade of the oil selected must fulfi l the
requirements in accordance with the
manufacturer's servicing schedule.
Consult the instructions at PEUGEOT
dealerships .
Remove the dipstick before fi lling.
Check the level after fi lling
(never exceed the max mark).
Screw the cap back onto the sump
before closing the bonnet.
LEVELS
If you have to remove/refi t the
engine style cover, handle it
with care to avoid damaging
the fi xing clips.
Dipstick 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 fl uid must be changed at
the intervals stated, according to the
manufacturer's servicing schedule.
Use fl uids recommended by the
manufacturer, which fulfi l DOT4
standards.
The level must be between the MIN
and MAX marks on the reservoir.
If fl uid has to be added frequently,
this indicates a failure which must be
checked by a PEUGEOT dealer as
soon as possible.
There are two marks
on the dipstick:

A = maximum
If you fi ll past this
mark, contact a
PEUGEOT dealer .

B = minimum
Never allow the level
to fall below this
mark.

CHECKS
Cooling system
Only use the fl uid 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 fl uid 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 fi lter, 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)
When this occurs with the engine
running, this is due to the start of
saturation of the particle emission
fi lter (exceptionally prolonged urban
driving conditions: low speed, long
traffi c jams, ...).
In order to regenerate the fi lter, you
are advised to drive at a speed of
more than 40 mph (60 km/h) as soon
as possible, when traffi c conditions
permit, for at least fi ve 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 fl uid 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 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 fl uid is harmful to health and
very corrosive.
Do not dispose of used oil, brake
fl uid or coolant into drains or onto
the ground but into the containers
dedicated to this use at PEUGEOT
dealerships .
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.

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
specifi c products.
In order to avoid damaging
the electrical units, high pressure
washing to clean the engine
compartment is strictly prohibited.
Oil filter
Change the fi lter regularly,
in accordance with the servicing
schedule. Refer to the servicing booklet to
fi nd 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.
Refer to the "Under the bonnet" section
of chapter 7. Particle emission filter (Diesel)
It is imperative that particle emission
fi lter 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 fl uid 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 fi lter permits continuous
and effective fi ltering of dust.
If the passenger compartment fi lter
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 fi lter.
By means of its second special active
fi lter, it contributes to the purifi cation
of the air breathed by the occupants
and to the cleanness of the passenger
compartment (reduction of allergic
symptoms, unpleasant odours and
greasy deposits).
Manual gearbox
Have the level checked in accordance
with the manufacturer’s servicing
schedule.
