Misfuel prevention (Diesel)*Mechanical device which prevents filling the tank of a Diesel vehicle with petrol. It avoids the risk of engine damage that can result from filling with the
wrong fuel.
Located in the filler neck, the misfuel prevention device appears when the filler cap is removed.
When a petrol filler nozzle is introduced into the
fuel filler neck of your Diesel vehicle, it comes
into contact with the flap. The system remains
closed and prevents filling.
Do not persist but introduce a Diesel type
filler nozzle.
* Depending on the country of sale.It remains possible to use a fuel can to
fill the tank.
In order to ensure a good flow of fuel,
do not place the nozzle of the fuel can
in direct contact with the flap of the
misfuel prevention device and pour
s l ow l y.
Travelling abroad
As Diesel fuel pump nozzles may
be different in other countries, the
presence of the misfuel prevention
device may make refuelling impossible.
Not all Diesel vehicles are fitted with
misfuel protection, so before travelling
abroad, we recommend that you check
with the PEUGEOT dealer network,
whether your vehicle is suitable for the
fuel pumps in the country in which you
intend to travel.

Closing
Before doing anything under the
bonnet, deactivate the Stop & Start
system to avoid any risk of injury
resulting from an automatic change to
S TA R T m o d e .
When the engine is hot, handle the
exterior safety catch and the stay with
care (risk of burns), using the protected
area.
When the bonnet is open, take care not
to damage the safety catch.
Because of the presence of electrical
equipment under the bonnet, it is
recommended that exposure to water
(rain, washing, ...) be limited.

Checking levels
The check is carried out either when
the ignition is switched on using the
oil level indicator in the instrument
panel for vehicles so equipped, or
using the dipstick.
Engine oil level
Checking using the dipstick
Check all of these levels regularly, in line with the manufacturer's service schedule. Top them up if necessary, unless other wise indicated.
If a level drops significantly, have the corresponding system checked by a PEUGEOT dealer or a qualified workshop.
It is normal to top-up the oil level between
two services (or oil changes). PEUGEOT
recommends that you check the level, and top-
up if necessary, every 3 000 miles (5 000 kms).A = MA X
B = MINIf you find that the level is above the A mark or
below the B mark, do not star t the engine
.
-

I
f the level is above the MAX mark (risk
of damage to the engine), contact a
PEUGEOT dealer or a qualified workshop.
-

I
f 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.
Take care when working under the
bonnet, as certain areas of the engine
may be extremely hot (risk of burns) and
the cooling fan could start at any time
(even with the ignition off).
To ensure that the reading is correct,
your vehicle must be parked on a level
sur face with the engine having been off
for more than 30 minutes.
The location of the dipstick is shown in the
corresponding underbonnet layout view.
F

T

ake the dipstick by its coloured grip and
remove it completely.
F

W

ipe the end of the dipstick using a clean
non-fluffy cloth.
F

R

efit 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 .

Topping-up the engine oil level
The location of the oil filler cap is shown in the
corresponding underbonnet layout view.
F
U
nscrew the oil filler cap to reveal the filler
aperture.
F

A
dd oil in small quantities, avoiding any
spills on engine components (risk of fire).
F

W
ait a few minutes before checking the
level again using the dipstick.
F

A
dd more oil if necessary.
F

A
fter checking the level, carefully refit the
oil filler 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 instrument panel
is not valid during the 30 minutes after
topping-up.
Engine oil change
Refer to the manufacturer's service schedule
for details of the interval for this operation.
In order to maintain the reliability of the engine
and emission control system, never use
additives in the engine oil.
Brake fluid level
Changing the fluid
Refer to the manufacturer's service schedule
for details of the interval for this operation.
Fluid specification
The brake fluid must conform to the
manufacturer's recommendations. The brake fluid level should be close
to the "MA X" mark. If it is not, check
the brake pad wear.

Screenwash fluid level
Top up the level when necessary.
Fluid specification
For optimum cleaning and to avoid freezing,
this fluid must not be topped up or replaced
with plain water.
In wintry conditions, it is recommended that you
use an ethyl alcohol or methanol based fluid.
Coolant level
Check the coolant level regularly.
It is normal to top-up this fluid
between services.When the engine is hot, the temperature of the
coolant is regulated by the fan.
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 the risk of scalding in the event of
an urgent need to top-up, with a cloth around
the cap, unscrew it by two turns to allow the
pressure to drop. When the pressure has
dropped, remove the cap and top-up the level.
Once the pressure has dropped, remove the
cap and top-up the level.
The cooling fan may star t after
switching off the engine: take care
with articles and clothing that might
be caught by the fan blades.
The check and top-up must only be done with
the engine cold.
A low coolant level presents a risk of serious
damage to your engine.
The coolant level should be close to the "MA X"
mark but should never exceed it.
If the level is close to or below the "MIN" mark,
it is essential to top-up.
Fluid specification
The coolant must conform to the
manufacturer's recommendations.

As soon as the traffic conditions permit,
Versions equipped with Stop & Start are
fitted with a 12 V lead-acid battery of
specific technology and specification.
Its replacement should be carried
out only by a PEUGEOT dealer or a
qualified workshop. regenerate the filter 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, this indicates a
low additive level.
For more information on Checking levels
,
refer to the corresponding section.
Unless otherwise indicated, check these components in accordance with the manufacturer's service schedule and according to your engine.
Other wise, have them checked by a PEUGEOT dealer or a qualified workshop.
Air filter and passenger compartment filter
Refer to the manufacturer's
service schedule for details of the
replacement intervals for these
components.
Oil filter
Replace the oil filter each time the
engine oil is changed.
Refer to the manufacturer's
service schedule for details of
the replacement interval for this
component.
12 V battery
The battery does not require any
maintenance.
However, check regularly that the
terminals are correctly tightened
(versions without quick release terminals) and
that the connections are clean.
For more information and the precautions to
take before starting work on the 12 V batter y ,
refer to the corresponding section. 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 filter may
have an adverse effect on the per formance
of the air conditioning system and generate
undesirable odours. The start of saturation of the particle
filter is indicated by the temporary
On a new vehicle, the first particle
filter regeneration operations may be
accompanied by a "burning" smell,
which is per fectly normal.
Following prolonged operation of the
vehicle at very low speed or at idle,
you may, in exceptional circumstances,
notice the emission of water vapour at
the exhaust on acceleration. This does
not affect the behaviour of the vehicle
or the environment.
