Maximum authorised load distributed over
the transverse roof bars, for a load height
not exceeding 40 cm (with the exception
of
bicycle carriers):
-
Hatchback: 65 kg.
-
SW: 80 kg .
For more information, contact a
PEUGEOT dealer or a qualified workshop.
If the height exceeds 40
cm, adapt the
speed of the vehicle to the profile of the
road to avoid damaging the roof bars and
the vehicle's fixing points.
For transporting objects which are longer
than the vehicle, refer to local legislation.
Recommendations
Distribute the load uniformly, taking care
to avoid overloading one of the sides.
Arrange the heaviest part of the load as
close as possible to the roof.
Secure the load firmly.
Drive gently: the vehicle will be more
susceptible to the effects of side winds
and its stability may be affected.
Regularly check the correct locking of the
roof bars, at least before each trip.
Remove the roof bars once they are no
longer needed.
If you use a roof box, contact a PEUGEOT
dealer or a qualified workshop to obtain
the compatible fixing parts. Sunroof
Do not operate the sunroof when using
roof bars – risk of major damage!
Bicycle/Accessory Carrier
Do not fit an accessory carrier to the
tailgate.

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 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

topping up.
Practical information

207
Changing the fluid
Refer to the manufacturer's service schedule
for details of the inter val for this operation.
Coolant level
Check the coolant level regularly.
It is normal to top up the fluid
between two services.
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. 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, wrap 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.
Screenwash fluid level
Top up to the required level when
necessary.
Fluid specification
The screenwash fluid must be topped up with
a
ready for use mix.
In winter (temperatures below zero), a fluid with
antifreeze must be used that is appropriate for
the prevailing conditions, in order to preser ve
the elements of the system (pump, tank, ducts,
e t c .) .
Diesel fuel additive level
(Diesel with particle filter)
The additive reser voir low level is
indicated by fixed illumination of this
warning lamp, accompanied by an
audible signal and a message that
the particle filter additive level is
too low.
To p p i n g u p
The reser voir must be topped up without delay
by a PEUGEOT dealer or a qualified workshop.
Level of AdBlue
An alert is triggered once the reser ve level is
reached.
For more information on the Indicators for
the AdBlue range, refer to the corresponding
section.
To avoid the vehicle being immobilised as per
regulations, you must top up the AdBlue tank.
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. Filling with pure water is prohibited under all
circumstances (risk of freezing, limestone
deposits, etc.).

engines), and in particular on topping up the
tank, refer to the corresponding section.
Checks
Unless otherwise indicated, check these
components in accordance with the
manufacturer's service schedule.
Other wise, have them checked by a
PEUGEOT
dealer or a qualified workshop.
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 on the precautions
to take before starting work on the 12 V
battery , refer to the corresponding section.
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.
Passenger compartment 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 .
A clogged passenger compartment
filter may have an adverse effect on
the per formance of the air conditioning
system and generate undesirable odours.
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 signalled by the temporary
illumination of this warning lamp
accompanied by a message warning
of 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.
