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 a PEUGEOT
dealer 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.
Take used oil to a PEUGEOT dealer 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). PEUGEOT
recommends that you check the level, and top
up if necessary, every 3,000
miles (5,000 km).
Checking using the dipstick
F Take the dipstick by its coloured grip and pull it out 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 marks A and B .
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 a PEUGEOT
dealer or a qualified workshop.
-

I
f the level is below the MIN mark, you must
top up the engine oil.
The location of the dipstick is shown in the
corresponding underbonnet layout view.

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 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 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
In order to maintain the reliability of the engine
and emissions 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 fluid
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.
Coolant level
Check the coolant level regularly.
It is normal to top up the fluid
between two services. 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.
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 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 to the required 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
This fluid must conform to the manufacturer's
recommendations.
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.
The check and top up must only be done with
the engine cold.

Air filter
Depending on the environment
(e.g. dusty atmosphere) and the
use of the vehicle (e.g. city driving),
replace it twice as often, if
necessary.
Oil filter
Change the oil filter each time the
engine oil is changed.
Particle filter (Diesel)
The start of saturation of the particle
filter is indicated by the temporary
illumination of this warning lamp
accompanied by a message about
the risk of the filter clogging up.
As soon as the traffic conditions permit,
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.
For more information on Checking levels ,
refer to the corresponding section. 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.
Manual gearbox
The gearbox does not require any
maintenance (no oil change).
Automatic gearbox
The gearbox does not require any
maintenance (no oil change).
Brake pads
Brake wear depends on the style
of driving, particularly in the case
of vehicles used in town, over short
distances. It may be necessary to
have the condition of the brakes
checked, even between vehicle
services.
Unless there is a leak in the circuit, a drop in
the brake fluid level indicates that the brake
pads are worn.
Brake disc wear
For information on checking brake
disc wear, contact a PEUGEOT
dealer or a qualified workshop.
Electric parking brake
This system does not require any
routine servicing. However, in the
event of a problem, have the system
checked by a PEUGEOT dealer or a
qualified workshop.

Comprising a compressor and a sealant
cartridge, it allows the temporary repair of
a tyre so that you can drive to the nearest
garage.
It is designed to repair most punctures which
could affect the tyre, located on the tyre tread
or shoulder.
The vehicle's electric system allows the
connection of the compressor for long
enough to inflate a tyre after a puncture
repair.
Composition of the kit
1. 12 V compressor, with integral pressure
gauge.
2. Sealant cartridge, with integral hose.
3. Speed limit sticker.
Repair procedure
