ing system or punctured tyre warning
lights.
WARNING LIGHTS SPECIFIC TO THE 4-DIAL INSTRUMENT PANEL
Engine oil pressure warning
light
This indicates that the engine oil pres-
sure is too low.
It is linked with the STOP warning
light.

Stop immediately if it is displayed

In the case of a lack of oil in the lubri-
cation circuit, top up the oil.
Contact a PEUGEOT dealer as soon
as possible. Coolant temperature
warning light
This indicates that the engine tempe-
rature is high.
It is linked with the STOP warning light.
Stop immediately.
Battery charge warning
light
When the engine is running, this indi-
cates a charging circuit fault (battery
terminals, alternator belt).
Consult a PEUGEOT dealer.

This indicates that one or more punc-
tured tyres have been detected.
A message on the multifunction display
indicates the wheel(s) concerned. It is

When the needle is in zone B , the
temperature is too high.
If the coolant temperature warning
light comes on (linked with the STOP
warning light), stop immediately.
Wait for the engine to cool down be-
fore topping up the level, if necessary.
As the cooling circuit is pressurised, in
order to prevent any risk of scalding,
unscrew the cap by two turns to allow
the pressure to drop.
When the pressure has dropped, re-
move the cap and top up the level, if
necessary.
Consult a PEUGEOT dealer. Stop immediately.

CHECKING THE LEVELS
These are normal maintenance opera-
tions which keep your vehicle in good
working order. Consult the instructions
in the PEUGEOT Network or in the
servicing booklet enclosed with this
handbook.
Dipstick There are two marks on
the dipstick:

A = maximum
Never fi ll past this mark.

B = minimum
To maintain the reliability
of engines and emission
control systems, the use
of additives in engine oil is
prohibited.
Oil level

 Check the level regularly and top
up between changes.
Check the level with the vehicle level,
the engine having been off for more
than 15 minutes, using the dipstick. Oil change
It is imperative that this is carried out
at the intervals specifi ed and the vis-
cosity of the oil chosen must meet the
requirements laid down in the manu-
facturer’s servicing schedule. Consult
the instructions in the PEUGEOT
Network.

Note : avoid used oil coming into pro-
longed contact with the skin. Empty
the used oil into the containers provi-
ded for this purpose in the PEUGEOT
Network. system is pressurised, wait for at least
one hour after the engine has stopped
before carrying out any work.
Oil filter
Replace the cartridge regularly in ac-
cordance with the recommendations
of the servicing schedule.
Brake fluid change
Use the fl uid recommended by the
manufacturer, which fulfi ls DOT4
Standards.
It is imperative that the brake fl uid is
changed at the intervals specifi ed in
accordance with the manufacturer’s
servicing schedule.

Note : avoid all contact with the skin,
the brake fl uid is harmful to health and
very corrosive. Used oil
Power steering reservoir
Use the fl uid recommended by the
manufacturer.

 Open the reservoir, with the engine
at ambient temperature. The level
should always be above the MIN.
mark and close to the MAX. mark.
Cooling system Windscreen and headlamp
wash level
To guarantee optimum cleaning and
avoid freezing, this fl uid should not be
topped up or replaced with water. Slacken the cap by two turns
to release the pressure to
prevent any risk of scalding.
When the pressure has drop-
ped, remove the cap and top up the
level.

Note : the coolant does not need to be
changed.
Use the fl uid recommended
by the manufacturer.
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 Do not dispose of used oil,
brake fl uid or coolant into
drains or onto the ground.

move/refi t the engine style co-
ver, handle it with care to avoid

CHECKS
At the start of winter, have
your battery checked by a
PEUGEOT dealer.
Have the fi lter elements re-
placed regularly. If you drive
in dusty conditions, change
them twice as often.
Air filter and passenger
compartment filter
Particle emission filter (Diesel)
It is imperative that the particle emis-
sion fi lter is maintained in accordan-
ce with the manufacturer’s servicing
schedule, by a PEUGEOT dealer.

Note : following prolonged operation
of the vehicle at very low speed or at
idle, you may, in exceptional circums-
tances, notice emissions of water va-
pour at the exhaust on acceleration.
This does not have any effect on the
performance of the vehicle or the en-
vironment.
On vehicles which are fi tted with a par-
ticle emission fi lter, the fan assembly
may operate after the vehicle has stop-
ped, even when the engine is cold. Where the handbrake travel is
too great or there is a reduc-
tion in the performance of the
system, the handbrake should
be adjusted.
Have the system checked by a
PEUGEOT dealer.
Handbrake
Disc wear status
For any information relating to chec-
king disc wear, contact a PEUGEOT
dealer.
FUEL SUPPLY CUT-OFF (PETROL) *
As a safety precaution, in certain cir-
cumstances, a mechanism prevents
fuel from reaching the engine.
To re-establish the fuel supply :
RUNNING OUT OF FUEL (DIESEL)
If you should run out of fuel, it is ne-
cessary to re-prime the circuit.
The repriming pump and the degas
screw are located under the bonnet
(see corresponding illustration in the
technical data section):
1.6 litre 16V HDI engine
- fi ll the fuel tank with at least fi ve li-
tres of diesel,
- squeeze and release the manual re-priming pump, until fuel appears
in the transparent pipe,
- operate the starter until the engine starts.
2 litre 16V HDI engine
- fi ll the fuel tank with at least fi ve li- tres of diesel,
- unscrew the degas screw,
- squeeze and release the manual repriming pump until diesel is seen
escaping via the degas screw,
- retighten the degas screw,
- operate the starter until the engine starts.
Brake pad wear depends on
the style of driving, in particu-
lar for vehicles which are used
in town, over short distances.
Brake pads It may be necessary to check
the thickness of the pads,
even between services.
* According to version.
To ensure the best perfor-
mance from components as
important as the power stee-
ring and the braking system,
the manufacturer selects and offers
specifi c products, only use products
recommended by PEUGEOT .
Battery
To prevent damage to the electrical
units, high pressure washing of the
engine compartment is strictly prohi-
bited .
 press the red button on the angle
of the front right-hand suspension
assembly, under the bonnet.
