Practical information
For more information on the precautions
to take before any 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.
Air filter
Depending on the environment and the
use of the vehicle (e.g. dusty atmosphere,
city driving), change it twice as often, if
necessary .
Passenger compartment
filter
Depending on the environment and the
use of the vehicle (e.g. dusty atmosphere,
city driving), change it twice as often, if
necessary .
A clogged passenger compartment filter
can adversely affect air conditioning
system performance and generate
undesirable odours.
Oil filter
Change the oil filter each time the engine
oil is changed.
Particle filter (Diesel)
In addition to the catalytic converter, this filter
actively contributes to the preservation of
air quality by trapping the unburnt pollutant
particles. Black exhaust fumes are therefore not
emitted.
Operation
This filter, inserted into the exhaust system,
accumulates the carbonaceous particles. The
engine management computer automatically
and periodically manages the removal of
carbonaceous particles (regeneration).
The regeneration procedure is triggered
according to the amount of accumulated
particles and the conditions of use of the vehicle.
During this phase, you may notice certain
phenomena - accelerated idling, triggering of
the cooling fan, increased smoke and increased
temperature at the exhaust - which have no
impact on the operation of the vehicle and the
environment.
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 while
accelerating. This has no impact on the
vehicle’s behaviour and the environment.
Due to the high exhaust temperatures
caused by the normal operation of the
particle filter, it is recommended not to park
the vehicle on flammable materials (grass, dry
leaves, pine needles, etc.) to avoid any risk of
fire.
Saturation/Regeneration
If there is a risk of clogging, this warning
lamp comes on, accompanied by a
message on the instrument panel display.
This warning is due to the start of saturation of
the particle filter (exceptionally long urban driving
conditions: reduced speed, traffic jams, etc.).
In order to regenerate the filter, it is
recommended to drive as soon as possible -
when traffic conditions and regulations permit
- at a speed of at least 37 mph (60 km/h), with
an engine speed above 2,000 rpm for about
15 minutes (until the warning lamp and/or the
message disappear).
If possible, avoid switching off the engine
before the end of filter regeneration; repeated
interruptions can lead to early deterioration of the
engine oil. It is not recommended to terminate
the filter regeneration with the vehicle stationary.
Malfunction
If this alert persists, do not ignore this warning;
this indicates that a malfunction has occurred in
the exhaust system/particle filter assembly.
Have it checked by a PEUGEOT dealer or a
qualified workshop.

Practical information
7Manual 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.
If this warning lamp comes on, have the
brake pads checked by a PEUGEOT
dealer or a qualified workshop.
After washing the vehicle, moisture, or in wintry conditions, ice can form on the
brake discs and pads: braking efficiency may
be reduced. Gently dab the brakes to dry and
defrost them.
Brake disc wear
For information on checking brake disc
wear, contact a PEUGEOT dealer or a
qualified workshop.
Manual parking brake
If you notice excessive brake lever travel
or decreased effectiveness, the parking brake must be adjusted, even between two
services.
This system must be checked by a PEUGEOT
dealer or a qualified workshop.
Diesel fuel filter
The Diesel fuel filter is located in the engine
compartment near the brake fluid reservoir.
If this warning lamp comes on, bleed the
filter.
You can also bleed it regularly at each engine oil
change.
Bleeding the water in the filter

► Couple a clear hose to the bleed screw
1 head.
►

Place the other end of the clear hose in a
container

.
► Loosen bleed screw 2 .
► Switch on the ignition.
►

W

►

Switch off the ignition.
►


T
ighten bleed screw 2.
►

Remove, then drain the clear hose and the
container

.
►

Start the engine.
►


Check that there are no leaks.
HDi engines make use of advanced
technology. Any intervention requires a
special qualification guaranteed by the
PEUGEOT


dealer network or a qualified
workshop .
Wheels and tyres
The inflation pressure of all tyres, including the spare wheel, must be
checked on "cold” tyres.
The pressures indicated on the tyre pressure
label are valid for "cold" tyres. If you have driven
for more than 10 minutes or more than 6 miles
(10 kilometres) at over 31 mph (50
km/h), add
0.3 bar (30 kPa) to the values indicated on the
label.
Under-inflation increases energy
consumption. Non-compliant tyre
pressures cause tyres to wear prematurely
and have an adverse effect on the vehicle's
road holding - risk of accident!

Special features
10Tipper truck

The lifting of the tipper is provided by a hydro-
electric unit powered by the vehicle's battery.


The ascent or descent is done by holding the
corresponding buttons of the magnetic and
removable remote control located on a support
inside the cab.
The lifting of the tipper is powered by unit's
motor.
The descent is powered by a solenoid valve
opening the strut's oil return.
An anti-drop system makes the descent of the
tipper safe whether static or lifting.
Safety recommendations

Never drive with the tail board down.
Ensure that there are no people or
obstacles present (on the ground and higher
up) when unloading.
Never leave the tipper raised when not in use.
Always tip with the upper part of the tail board
locked.
Observe the payload on the tare plate
attached to the vehicle.
Check regularly that the suspension is in
good condition and that the tyres are inflated
to the recommended pressure.
Spread the load evenly in the tipper.
Transport products of the same type which
are free-flowing or easy to move.
Never drive, even slowly, with the tipper
raised.


Do not place a load greater than 150 kg
on the open tail board.
Tip on to a flat and hard surface: sloping or loose ground can cause a
displacement of the centre of gravity which can
affect the stability of the unit.

Maintenance
Reservoir
Regularly check and top up the engine oil level.
Change the oil once a year. If the oil contains
water, change it.
Regularly check the condition of the hose and
ensure the hydraulic system is properly sealed.
Pump and motor
No servicing required. The rolling elements are
permanently lubricated and the bearings are
lubricated by the pumped oil.
Lubrication
The pins of the tipper truck and the ram do not
contain lubricant. Regularly lubricate the hinges
and the grab handles of the side boards as well
as the retaining hooks of the rear board.
Sub-frame and tipper truck
For maximum service life, you are advised to
maintain your tipper truck by regularly washing it
using a power washer.
Carry out any required paint touch-ups quickly to
prevent the spread of rust.
After 8 months of use, check the tightening torque of the connection
between the chassis and the underbody (in
accordance with the manufacturer's
bodybuilding recommendations).
