2018 Peugeot 508 fuel pressure

7
Limit the causes of excess
consumption
Spread loads throughout the vehicle; place
the heaviest items at the back of the boot, as
close as possible to the rear seats.
Limit the loads carried in the vehicle and
reduce wind resistance (roof bars, roof rack,
bicycle carrier, trailer, etc.). Preferably, use a
roof box.
Remove roof bars and roof racks after use.
At the end of winter, remove snow tyres and
refit your summer tyres.
Observe the recommendations
on maintenance
Check the tyre pressures regularly, when cold,
referring to the label in the door aperture,
driver's side.
Carry out this check in particular:
-
b
efore a long journey,
-

a
t each change of season,
-

a
fter a long period out of use.
Do not forget the spare wheel and the tyres on
any trailer or caravan. Have your vehicle ser viced regularly (engine
oil, oil filter, air filter, cabin filter, etc.) and
obser ve the schedule of operations in the
manufacturer's service schedule.
When filling the tank, do not continue after the
3
rd cut-off of the nozzle to avoid over flow.
At the wheel of your new vehicle, it is only
after the first 1,900 miles (3,000 kilometres)
that you will see the fuel consumption settle
down to a consistent average. With a BlueHDi Diesel engine, if the SCR
system is faulty, your vehicle becomes
polluting. As soon as possible, visit a
PEUGEOT dealer or a qualified workshop to
make your vehicle’s level of nitrogen oxides
emissions compliant to the standard.

The under-inflation detection system does
not replace the need for vigilance on the
part of the driver.
This system does not avoid the need to
check the tyre pressures (including the
spare wheel) every month as well as
before a long journey.
Driving with under-inflated tyres worsens
road-holding, lengthens braking distances,
causes premature wear of the tyres,
particularly in adverse conditions (heavy
loads, high speeds, long journeys).Driving with under-inflated tyres
increases fuel consumption.
The inflation pressures defined for your
vehicle can be found on the tyre pressure
label.
For more information on the
Identification markings , refer to the
corresponding section. Checking tyre pressures
This check should be done when the tyres
are "cold" (vehicle stopped for 1 hour or
after a journey of less than 6 miles (10 km)
at moderate speeds).
Other wise, add 0.3 bar to the pressures
shown on the label.
Snow chains
The system does not have to be
reinitialised after fitting or removing snow
chains.
Under-inflation alert
This is indicated by continuous
illumination of this warning lamp, an
audible signal and, depending on
equipment, the display of a message.
F
R

educe speed immediately, avoid excessive
steering movements and sudden braking.
F
S

top the vehicle as soon as it is safe to do so.
The loss of pressure detected does not
always cause visible bulging of the tyre.
Do not satisfy yourself with just a visual
check. F

I
f you have a compressor, such as the one
in the temporary puncture repair kit, check
the pressures of the four tyres when cold.
F
I
f it is not possible to make this check
immediately, drive carefully at reduced
speed.
or
F
I
n case of a puncture, use the temporary
puncture repair kit or the spare wheel
(depending on equipment).
The alert is kept active until the system is
reinitialised.
Reinitialisation
The system must be reinitialised after any
adjustment to the pressure of one or more
tyres, and after changing one or more wheels.
Before reinitialising the system, ensure
that the pressures of the four tyres
are correct for the conditions of use
of the vehicle and conform to the
recommendations on the tyre pressure
label.
The under-inflation alert can only be relied
on if the reinitialisation of the system has
been done with the pressures in the four
tyres correctly adjusted.
The under-inflation detection system
does not give a warning if a pressure is
incorrect at the time of reinitialisation.

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.).

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/drum wear
For any information on checking
brake disc wear, contact a
PEUGEOT dealer or a qualified
workshop.
Electric parking brake
This system does not require any
specific check. However, in the
event of a problem, have the system
checked by a PEUGEOT dealer or a
qualified workshop.
For more information on the Electric
parking brake , refer to the corresponding
section.
Wheels and tyres
The pressure must be checked on
all tyres, including the spare wheel,
when the tyres are "cold", at least
once a month and before a long
j o u r n ey. Driving with worn or damaged tyres reduces
braking efficiency and control of the vehicle's
steering. Regular inspections of the condition
of tyres (tread and sides) and rims are
recommended as well as making sure that
valves are fitted.
Using different size wheels and tyres from
those specified can affect the lifetime of tyres,
wheel rotation, ground clearance and the
speedometer reading and have an adverse
effect on road holding.
Fitting different tyres on the front and rear axles
can cause the ESC to mistime.
Only use products recommended by
PEUGEOT or products of equivalent
quality and specification.
In order to optimise the operation of
components as important as those in the
braking system, PEUGEOT selects and
offers very specific products.
After washing the vehicle, dampness, or
in wintry conditions, ice can form on the
brake discs and pads: braking efficiency
may be reduced. Make light brake
applications to dry and defrost the brakes.
The pressures given 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 more than 31 mph (50 km/h),
0.3 bar (30 kPa) should be added to the values
given on the label.
Under-inflation increases fuel consumption.
Non-compliant tyre pressure causes premature
wear on tyres and has an adverse effect on the
vehicle's road holding – Risk of an accident!

Advice on care and
maintenance
Recommendations on the care and
maintenance of your vehicle are given in the
Warranty and Maintenance Record.
Headlamps and lamps
The headlamps have polycarbonate
lenses with a protective coating.
Do not clean them with a dry or abrasive
cloth, nor with detergent or solvent
products.
Use a sponge and soapy water.
The use of a high pressure jet wash for
cleaning the headlamps, lamps and their
surrounds may damage the lacquer and
seals.
Observe the recommendations on
pressure and distance for jet washing.
First clean persistent stains with a sponge
and warm soapy water.
Leather
Leather is a natural product. Appropriate
regular care and cleaning is essential for
its

durability. Refer to your vehicle's Warranty and
Maintenance Record for information on
all
the special precautions to obser ve.
AdBlue® (BlueHDi engines)
To respect the environment and ensure
compliance with the Euro 6 standard, without
adversely affecting the per formance or fuel
consumption of its Diesel engines, PEUGEOT
has taken the decision to equip its vehicles
with a system that associates SCR (Selective
Catalytic Reduction) with a Diesel particle filter
(DPF) for the treatment of exhaust gases.
SCR system
Using a fluid called AdBlue® that contains
urea, a catalytic converter turns up to 85%
of nitrogen oxides (NOx) into nitrogen and
water, which are harmless to health and the
environment.
The AdBlue
® is contained in
a
special tank holding about
17


litres. An alert system is triggered automatically once
the reser ve level is reached: you can then drive
for a further 1,500 miles (2,400
km) before the
tank is empty.
Once the AdBlue
® tank is empty, a system
r
equired by regulations prevents starting
of the engine.
If the SCR system is defective, the level of
emissions from your vehicle will no longer
meet the Euro 6 standard: your vehicle
becomes polluting.
In the event of a confirmed fault with the
SCR system, you must go to a PEUGEOT
dealer or a qualified workshop as soon
as possible: after a running distance of
685 miles (1,100

km), a system will be
triggered automatically to prevent engine
starting.
In either case, a range indicator gives you
the distance you can travel before the
vehicle is immobilised.
For more information on the Warning and
indicator lamps and associated alerts,
refer to the corresponding section.
