Checking levels
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 the dealer
network or a qualified workshop.The fluid must comply with the
manufacturer's recommendations and with
the vehicle's engine.
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).
Used products
Avoid prolonged contact of used oil or
fluids with the skin.
Most of these fluids are harmful to health
or indeed very corrosive. Do not discard used oil or fluids into
sewers or onto the ground.
Return used oil to the dealer network or
a qualified workshop and dispose of it in
the containers reser ved for this purpose.
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 vehicles equipped with an
electric gauge, or using the dipstick.
To ensure that the reading is correct, your
vehicle must be parked on a level sur face
with the engine stopped for more than
30


minutes.
It is normal to top up the oil level between two
ser vices (or oil changes). We recommend that
you check the level, and top up if necessary,
every 3,000 miles (5,000 km).
Checking using the dipstick
The location of the dipstick is shown in the
corresponding underbonnet layout view.
F
T
ake the dipstick by its coloured grip and
pull it out completely. A = MA X
B = MIN
If 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 the dealer
network 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. F
W
ipe the end of the dipstick using a clean
non-fluffy cloth.

pull it out again to make the visual check:
the correct level is between marks A and B .

Topping up the engine oil level
F Locate the oil filler cap in the engine compartment of your vehicle.
For more information about petrol or Diesel
engine, refer to the corresponding section.
F

U
nscrew the oil filler cap to access the filler
opening.
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 ignition-triggered oil
level indicator in the instrument panel does not
provide a valid information during 30 minutes.
Engine oil change
Refer to the manufacturer's service schedule
for inter val details 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
The brake fluid level should be close
to the "MA X" mark. If it is not, check
the brake pad wear.
Changing the coolant
Refer to the manufacturer's service schedule
for details of the inter val for this operation.
Fluid specification
This fluid must conform to the manufacturer's
recommendations.
Power steering fluid level
The fluid level should be close to
the "MA X" mark. Verify this, with the
engine off, by reading the level on
the filler neck.
Coolant level
Check the coolant level regularly.
It is normal to top up the fluid
between two services. To ensure that the reading is correct, your
vehicle must be parked on a level sur face with
the engine cool.
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.
A low coolant level presents a risk of serious
damage to your engine.
When the engine is warm, 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 when you need to
top up in an emergency, place a cloth around
the cap and unscrew the cap by two turns to
allow the pressure to drop.
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.
Fluid specification
The brake fluid must conform to the
manufacturer's recommendations.

Air filter and passenger compartment filter
Refer to the manufacturer’s
ser vice schedule 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 filter may
have an adverse effect on the per formance
of the air conditioning system and generate
undesirable odours.
Oil filter
Change the oil filter each time the
engine oil is changed.
Refer to the manufacturer’s
ser vice schedule for details of
the replacement inter val for this
component.
Particle filter (Diesel)
Depending on the version of the instrument
panel you have, the start of saturation of the
particle filter is indicated by:
Manual gearbox
The gearbox does not require any
maintenance (no oil change).
Automatic gearbox
The gearbox does not require any
maintenance (no oil change).
- fixed illumination of the particle filter warning lamp, accompanied
by an audible signal and a
message that there is a risk of
blockage of the particle filter,
or
-
t
emporary illumination of
the Ser vice warning lamp,
accompanied by an audible
signal and a message that
there is a risk of blockage of the
particle filter. 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.
Traffic conditions permitting, regenerate
the filter by driving at a speed of at least
37 mph (60 km/h) until the warning lamp
goes off.
If the warning lamp stays on, this indicates
a low Diesel additive level.

refer to the corresponding section.

Temporary puncture
repair kit
This kit comprises a compressor and a sealant
cartridge.
It allows the temporary repair of a tyre.
You are then able to go to the nearest garage.
It is designed to repair most punctures
which could affect the tyre, located on the
tyre tread or shoulder.
Its compressor can be used to check and
adjust the pressure of the tyre.
Tyre under-inflation detection
If the vehicle is fitted with tyre under-
inflation detection, the under-inflation
warning lamp will remain on after the
wheel has been repaired until the system
is reinitialised by a dealer or a qualified
workshop.
The vehicle's electric system allows the
connection of the compressor for long
enough to inflate a tyre after a puncture
repair. Only
the 12 V socket at the front of
the vehicle allows the compressor to be
connected for long enough to repair or
inflate the vehicle tyre.
The other 12 V sockets of the vehicle
are not designed to be used with the
compressor.
Access to the kit Composition of the kit
1.
12 V compressor, with built-in pressure
gauge.
2. Bottle of sealant, with built-in hose.
3. Speed limit sticker.
