Operating fault
In the event of a malfunction with the
system, the "ECO OFF" switch warning
lamp fl ashes, then comes on continu-
ously.
Have it checked by a PEUGEOT dealer
or a qualifi ed workshop.
In the event of a fault in STOP mode,
the vehicle may stall. It is then neces-
sary to switch off the ignition and start
the engine again using the key.
Maintenance
Before working under the bonnet,
deactivate the Stop & Start system
to avoid any risk of injury result-
ing from automatic operation of
START mode.
This system requires a battery with a
special specifi cation and technology
(reference numbers available from a
PEUGEOT dealer or a qualifi ed work-
shop).
Fitting a battery not listed by
PEUGEOT introduces the risk of mal-
function of the system.
The Stop & Start system makes
use of advanced technology. All
work on this battery must be done
by a PEUGEOT dealer or a quali-
fi ed workshop.

CHECKS
CHECKING LEVELS
Engine oil level
The check is carried out either
when the ignition is switched
on using the oil level indicator
in the instrument panel for ve-
hicles with and electric oil level gauge,
or using the dipstick. It is normal to top up the oil level
between two services (or oil chang-
es). PEUGEOT recommends that
you check the level, and top up
if necessary, every 3 000 miles
(5 000 kms).
Take care when working under the
bonnet, as certain areas of the en-
gine may be extremely hot (risk of
burns) and the cooling fan could
start at any time (even with the ig-
nition off). A = MAX
To ensure that the reading is correct,
your vehicle must be parked on a level
surface and the engine having been off
for more than 30 minutes. Check all of these levels regularly, in
line with the warranty and maintenance
record. Top them up if necessary, un-
less otherwise indicated.
If a level drops signifi cantly, have the
corresponding system checked by a
PEUGEOT dealer or a qualifi ed work-
shop. Checking using the dipstick
Refer to the "Petrol engine" or "Diesel
engine" section for the location of the
dipstick in the engine compartment of
your vehicle.
 Take the dipstick by its coloured grip and remove it completely.
 Wipe the end of the dipstick using a clean non-fl uffy cloth.
 Refi t the dipstick and push fully down, then pull it out again to make
the visual check: the correct level is
between the marks A and B . B = MIN
If you fi nd that the level is above the A
mark or below the B mark, do not start
the engine .
- If the level is above the MAX mark
(risk of damage to the engine), con-
tact a PEUGEOT dealer or a quali-
fi ed workshop.
- If the level is below the MIN mark,
you must top up the engine oil.
Oil grade
Before topping-up the oil or changing
the oil, check that the oil is the correct
grade for your engine and conforms to
the manufacturer's recommendations.

CHECKS

Brake fluid level
The brake fl uid level should be
close to the "MAX" mark. If it is
not, check the brake pad wear.
Power steering fluid level
The power steering fl uid level
should be close to the "MAX"
mark. With the engine cold,
unscrew the cap to check the
level.
Changing the fl uid
Refer to the warranty and maintenance
record for details of the interval for this
operation.
When the engine is warm, the tempera-
ture of the coolant is regulated by the
fan.
Coolant level
The coolant level should be
close to the "MAX" mark but
should never exceed it.
The cooling fan may start after
switching off the engine: take care
with articles and clothing that might
become caught by the fan blades.
Fluid specifi cation
The coolant must conform to the manu-
facturer's recommendations.
Fluid specifi cation
The brake fl uid must conform to the
manufacturer's recommendations.
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.
Topping up the engine oil level
Refer to the "Petrol engine" or "Diesel
engine" section for the location of the oil
fi ller cap in the engine compartment of
your vehicle.
 Unscrew the oil fi ller cap to reveal
the fi ller aperture.
 Add oil in small quantities, avoiding any spills on engine components
(risk of fi re).
 Wait a few minutes before checking the level again using the dipstick.
 Add more oil if necessary.
 After checking the level, carefully re- fi t the oil fi ller cap and the dipstick in
its tube.
After topping up the oil, the check
when switching on the ignition with
the oil level indicator in the instru-
ment panel is not valid during the
30 minutes after topping up.
Engine oil change
Refer to the warranty and maintenance
record 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.

CHECKS
CHECKS
Battery
The battery does not require any
maintenance.
However, check that the termi-
nals are clean and correctly tight-
ened, particularly in summer and
winter.
When carrying out work on the battery, refer
to the "Battery" section for details of the pre-
cautions to be taken before disconnecting
the battery and following its reconnection.
Air filter and passenger compartment filter
Refer to the warranty and
maintenance record for details
of the replacement intervals
for these components.
Depending on the environment
(e.g. dusty atmosphere) and the use of
the vehicle (e.g. city driving), replace
them twice as often if necessary .
A clogged passenger compartment fi lter
may have an adverse effect on the per-
formance of the air conditioning system
and generate undesirable odours.
Oil filter
Replace the oil fi lter each time
the engine oil is changed.
Refer to the warranty and
maintenance record for details
of the replacement interval for
this component.
The presence of this label, in particular
with the Stop & Start system, indicates
the use of a specifi c 12 V lead-acid bat-
tery with special technology and specifi -
cation. The involvement of a PEUGEOT
dealer or a qualifi ed workshop is essen-
tial when replacing or disconnecting the
battery.
Particle emission filter (Diesel)
On a new vehicle, the fi rst particle
fi lter regeneration operations may
be accompanied by a "burning"
smell, which is perfectly normal.
Following prolonged operation of
the vehicle at very low speed or at
idle, you may, in exceptional cir-
cumstances, notice the emission
of water vapour at the exhaust on
acceleration. This does not affect
the behaviour of the vehicle or the
environment. The start of saturation of the
particle emissions fi lter is in-
dicated by the temporary illu-
mination of this warning lamp,
accompanied by an audible
signal and a message on the risk of
blockage of the particle emissions fi lter.
As soon as the traffi c conditions per-
mit, regenerate the fi lter by driving at a
speed of at least 40 mph (60 km/h) until
the warning lamp goes off.
If the warning lamp stays on, refer to the
"Additive level" section.
Unless otherwise indicated, check these
components in accordance with the war-
ranty and maintenance record and accord-
ing to your engine.
Otherwise, have them checked by a
PEUGEOT dealer or a qualifi ed workshop.
