TYRE UNDER-INFLATION
DETECTION
Sensors check the tyre pressure dur-
ing driving and trigger a warning in the
event of malfunction.
Pressure CheckWith the ignition on and the
vehicle having been stationary
for approximately 15 minutes,
and after the engine oil level,
this indicator light comes on
on the instrument panel screen to indi-
cate that the system is measuring the
tyre pressures.
Pressure OK
This indicator light comes
on on the instrument panel
screen if all of the tyre pres-
sure values measured are
correct.
If this indicator light does not appear,
contact a PEUGEOT dealer to have
the system checked. Puncture
This warning light, accom-
panied by the audible sig-
nal and the message on the
multi-function display locat-
ing the wheel concerned, is
followed by illumination of the STOP
warning light.
Stop immediately, avoiding any sud-
den movement of the steering wheel
and the brakes.
Change the damaged wheel (punc-
tured or very deflated tyre), and have
the tyre pressure checked as soon as
possible.
Note: this message is also
displayed when one of the
wheels is away from the ve-
hicle (being repaired) or when
one or more wheels without a sensor
are fitted. All repairs and changing of
tyres on a wheel fitted with this
system must be carried out by
a PEUGEOT dealer.
If, when changing a tyre, you install a
wheel which is not detected by your
vehicle, you must have the system
reinitialised by a PEUGEOT dealer.
The tyre under-inflation detection sys-
tem is an aid to driving which does not
replace the need for the driver to be
vigilant or to drive responsibly.
This system does not eliminate the
need to have the tyre pressure checked
regularly (see manufacturer’s label) to
ensure that the optimum dynamic per-
formance of the vehicle is maintained
and prevent premature wear of the
tyres, particularly in arduous driving
conditions (heavy load, high speed).
The tyre pressures must be checked
cold, at least once a month. Remem-
ber to check the pressure of the spare
wheel.
The tyre under-inflation detection sys-
tem may experience temporary inter-
ference due to radioelectric emissions
on a frequency close to that used by
the system.
Flat tyre
This warning light is accom-
panied by the audible signal
and the message on the multi-
function display locating the
wheel concerned.
If this warning light comes on, have
the tyre pressure checked as soon as
possible. Sensor(s) not detected or faulty
This warning light is accom-
panied by the audible sig-
nal and the message on the
multi-function display which
indicates that under-inflation
detection is absent from one (or sev-
eral) wheel(s) or that there is a fault in
the system.
Contact a PEUGEOT dealer to replace
the faulty sensor(s).

Bonnet strut
Secure the strut in its housing to hold
the bonnet open.
Before closing the bonnet, replace the
strut in its clip.
OPENING THE BONNET
From inside: pull the handle on the
left-hand side under the fascia to-
wards you.
From outside: lift the catch and raise
the bonnet. To avoid any risk of burns, only
handle the bonnet strut by the
protective foam.
To close
Lower the bonnet and release it at the
end of its travel. Check that the bonnet
is properly locked.

To maintain the reliability of
engines and emission control
systems, the use of additives
in engine oil is prohibited.Cooling systemCHECKING THE LEVELS
These are normal maintenance opera-
tions which keep your vehicle in good
working order. Consult the instructions
in the PEUGEOT Network, on the In-
fotec site or in the servicing booklet
enclosed with this handbook.
DipstickThere are two marks on
the dipstick:
A = maximum
Never fill past this mark.
B = minimum
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. Important:
if you have to remove/
refit the engine style cover, han-
dle it with care to avoid damaging
the fixing clips. Oil change
It is imperative that this is carried out
at the intervals specified 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 Net-
work or on the Infotec site.
Note:
avoid used oil coming into pro-
longed contact with the skin. Empty
the used oil into the containers provid-
ed for this purpose in the PEUGEOT
Network.
Oil filter
Replace the cartridge regularly in ac-
cordance with the recommendations
of the servicing schedule.
Brake fluid change
Use the fluid recommended by the
manufacturer, which fulfils DOT4
Standards.
It is imperative that the brake fluid is
changed at the intervals specified in
accordance with the manufacturer’s
servicing schedule.
Note: avoid all contact with the skin,
the brake fluid is harmful to health and
very corrosive. Use only the fluid recommend-
ed by the manufacturer.
Note: the coolant does not need to be
changed.
When the engine is warm, the tem-
perature of the coolant is controlled by
the engine fan. As this fan can oper-
ate with the ignition key removed and
because the cooling system is pressu-
rised, wait for at least one hour after
the engine has stopped before carry-
ing out any work.
Slacken the cap to the first
notch to release the pressure
to prevent any risk of scald-
ing. When the pressure has
dropped, remove the cap and top up
the level with coolant.
The engine fan can operate
after the vehicle has stopped.

For best quality cleaning and for your
safety, to see and be seen, we would
advise that you use products of the
PEUGEOT Universal range.At the start of winter, have
your battery checked by a
PEUGEOT dealer.

CHECKS
Have the filter elements re-
placed regularly.
If you drive
in dusty conditions, change
them twice as often.
Air filter and passenger
compartment filter
Brake pad wear depends on
the style of driving, in par-
ticular for vehicles which are
used in town, over short dis-
tances.
Brake pads
It may be necessary to check
the thickness of the pads,
even between services. Where the handbrake travel
is too great or there is a re-
duction in the performance
of the system, the handbrake
should be adjusted.
Have the system checked by a
PEUGEOT dealer.
Handbrake
To ensure the best perform-
ance from components as im-
portant as the power steering
and the braking system, the
manufacturer selects and offers spe-
cific products, only use products rec-
ommended by PEUGEOT.
To prevent damage to the electrical
units, high pressure washing of the
engine compartment is strictly prohib-
ited .
Power steering fluid level
Use the fluid recommended by the
manufacturer.
 Open the reservoir, with the engine
at ambient temperature, the level
should always be above the MIN
mark, close to the MAX mark.
Particle emission filter -
Additive reservoir (Diesel)
It is imperative that the maintenance of
the particle emission filter and the fill-
ing of the additive reservoir are carried
out by a PEUGEOT dealer in accord-
ance with the manufacturer’s servicing
schedule.

For any information relating to check-
ing disc wear, contact a PEUGEOT
