Stop & Start
The Stop & Start system puts the engine
t emporarily into standby – STOP mode – during
stops in traffic (red lights, traffic jams, etc.). The
engine restarts automatically – START mode –
as soon as you want to move off.
The restart takes place instantly, quickly and
silently.
Per fect for urban use, the Stop & Start system
reduces fuel consumption and exhaust
emissions as well as the noise level when
stationary.
Operation
Going into engine STOP mode
This indicator lamp comes on in the
instrument panel and the engine goes
into standby automatically: -

W
ith a manual gearbox
, at speeds below
2 mph (3 km/h) (with BlueHDi 130 S&S
engine) or with the vehicle stationary (other
engines), when you place the gear selector
in neutral and release the clutch pedal.
- With an automatic gearbox , vehicle
stationary, when you press the brake pedal
or place the gear selector lever in position N .
Stop & Star t time counter
(minutes/seconds or hours/
minutes)
A time counter calculates the time spent in STOP
mode during a journey.
It resets to zero every time the ignition is switched on.
For your comfort, during parking
manoeuvres, STOP mode is not available
for a few seconds after coming out of
reverse gear.
The Stop & Start system does not modify
the vehicle's functions, such as, for
example, braking, power steering, etc.
A slight delay between the vehicle
stopping and the engine cutting out may
be noticed.
Never refuel with the engine in STOP
mode; you must switch off the ignition.
Special cases: STOP mode not
available
STOP mode does not activate, mainly when:
-
t he vehicle is on a steep slope (rising or
falling),
-

t
he driver's door is open,
-

t
he driver's seat belt is not fastened,
-

t
he vehicle has not exceeded 6 mph
(10
km/h) since the last engine start by the
driver,
-

t
he electric parking brake is applied or being
applied,
-

t
he engine is needed to maintain a
comfortable temperature in the passenger
compartment,
-

d
emisting is active,
-

s
ome temporary conditions (battery charge,
engine temperature, braking assistance,
exterior temperature, etc.) make this
necessary to ensure control of a system.
In this case, this indicator lamp flashes
for a few seconds then goes off.
This operation is perfectly normal.
Going into engine START mode
This indicator lamp goes off and the
engine restarts automatically:
The system adapts its gear shift
recommendation according to the driving
conditions (slope, load, etc.) and the
driver’s requirements (power, acceleration,
b r a k i n g , e t c .) .
The system never suggests:
-
e

ngaging first gear,
-
enga

ging reverse gear.
Driving

167
The tyre under-inflation detection system
does not replace the need for vigilance on
the part of the driver.
This system still requires you to check
the tyre inflation pressures (including
the spare wheel) every month as well as
before a long journey.
Driving with under-inflated tyres impairs
handling, extends braking distances and
causes early tyre wear, particularly in
adverse conditions (heavy loads, high
speeds, long journeys).Driving with under-inflated tyres
increases fuel consumption. The tyre pressure specifications for your
vehicle can be found on the tyre pressure
label.
For more information on the
Identification markings
, refer to the
corresponding section.
Tyre pressures should be checked 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 (when hot), 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 warning is indicated by fixed
illumination of this warning lamp, an
audible signal and, depending on
the equipment installed, a message
displayed on the screen.
It compares the information given by the
wheel speed sensors with reference values,
which must be reinitialised after ever y tyre
pressure adjustment or wheel change
.
The system triggers an alert as soon as it
detects a drop in the pressure of one or more
tyres.

Do not satisfy yourself with just a visual
check.
F
I
n the event of a puncture, use the
temporary puncture repair kit or the spare
wheel (depending on equipment),
or
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,
or
F
i
f it is not possible to carry out this check
immediately, drive carefully at reduced
speed.
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.

Fuel tank
Tank capacity: about 53 litres (or 45 litres
depending on the version).
Opening
Refilling
At least 6 litres of fuel must be added, in order
t o be registered by the fuel gauge.
Opening the filler cap may create a noise
caused by an inrush of air. This is entirely
normal and results from the sealing of the fuel
system. F

Your vehicle is fitted with a catalytic converter,
a device which helps to reduce the level of
harmful emissions in the exhaust gases.
For petrol engines, you must use unleaded
fuel.
The filler neck is narrower, admitting petrol
nozzles only.
If you have put in the wrong fuel for
your vehicle, you must have the tank
drained and refilled with the correct
fuel before you star t the engine.
For the Puretech 225 S&S EAT8 engine, the
use of RON98 lead-free petrol is recommended
to guarantee optimum operation of the engine.
Low fuel level
When the low fuel level in the tank is
reached, this warning lamp comes on
in the instrument panel, accompanied
by an audible warning and a message.

Practical information

171
When it first comes on, less than 6 litres of fuel
r emain in the tank.
You must refuel as soon as possible to avoid
running out of fuel.
Fuel cut- of f
Your vehicle is fitted with a safety system that
cuts off the supply of fuel in the event of an
impact.
If your vehicle is fitted with Stop & Start,
never refuel with the engine in STOP
mode; you must switch off the ignition.
Diesel misfuel prevention
Mechanical device which prevents filling the
tank of a Diesel vehicle with petrol. It helps
avoid the risk of engine damage that can result
from filling with the wrong fuel.
Located in the filler neck, the misfuel
prevention device appears when the filler cap
is removed. It is still possible to use a fuel can to fill the
t a n k s l ow l y.
In order to ensure a good flow of fuel,
do not place the nozzle of the fuel can in
direct contact with the flap of the misfuel
prevention device.Driving abroad
As Diesel fuel pump nozzles may be
different in other countries, the presence
of the misfuel prevention device may make
refuelling impossible.
Not all Diesel vehicles are fitted with
misfuel protection, so before travelling
abroad, we recommend that you check
with the PEUGEOT dealer network,
whether your vehicle is suitable for the
fuel pumps in the country in which you
intend to travel.
When a petrol filler nozzle is introduced into the
Diesel tank, it comes into contact with the flap.
The system remains closed and prevents filling.
Do not persist but introduce a Diesel type
filler nozzle.

Compatibility of fuels
Fuel used for petrol engines
The petrol engines are compatible with biofuels
that conform to current and future European
standards and which can be obtained from
filling stations:Petrol that meets standard EN228,
mixed with a biofuel that meets standard
EN15376.
The only petrol additives authorised for
use are those that meet the B715001
standard.
Fuel used for Diesel
engines
The Diesel engines are compatible with
biofuels that conform to current and future
European standards and which can be
obtained from filling stations: For more information, contact a PEUGEOT
dealer or a qualified workshop.
The use of any other type of (bio)fuel
(vegetable or animal oils, pure or diluted,
domestic fuel, etc.) is strictly prohibited
(risk of damage to the engine and fuel
syste m). The only Diesel additives authorised for
use are those that meet the B715000
standard.
Diesel at low temperature
At temperatures below 0°C (+32°F), the
formation of paraffins in summer-type Diesel
fuels could result in an abnormal operation
of the fuel supply circuit. To avoid this, we
recommend using winter-type Diesel fuel and
keeping the fuel tank more than 50% full.
If, despite this, at temperatures below -15°C
(+5°F) the engine has problems starting,
just leave the vehicle in a garage or heated
workshop for a little while.
Travelling abroad
Cer tain fuels could damage the engine of
your vehicle.
In cer tain countries, the use of a par ticular
fuel may be required (specific octane
rating, specific trade name, etc.) to ensure
correct operation of the engine.
For any additional information, contact a dealer.
Diesel fuel that meets standard
EN590

mixed with a biofuel that meets
standard EN14214 (possibly containing
up to 7% Fatty Acid Methyl Ester), Diesel fuel that meets standard
EN16734

mixed with a biofuel that meets
standard EN14214 (possibly containing
up to 10% Fatty Acid Methyl Ester),
Paraffinic Diesel fuel that meets
standard EN15940

mixed with a biofuel
that meets standard EN14214 (possibly
containing up to 7% Fatty Acid Methyl
Ester).
B20 or B30 fuel that meets the standard
EN16709 can be used with your Diesel
engine. However, the use of this
fuel, even occasional, requires strict
application of the special ser vicing
conditions referred to as "Arduous
conditions".
Practical information

186
When the engine is hot, the temperature of this
fluid 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.
Fluid specification
This fluid must conform to the manufacturer's
recommendations.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
For optimum cleaning and to avoid freezing,
this fluid must not be topped up or replaced
with plain water. In wintry conditions, it is recommended
that you use an ethyl alcohol or methanol
based fluid.
Diesel fuel additive level
(Diesel with particle filter)
A low additive level is indicated by
illumination of this warning lamp,
accompanied by an audible warning
and a message in the instrument
panel screen.
To p p i n g u p
This additive must be topped up without delay
by a PEUGEOT dealer or a qualified workshop.
Checks
Unless otherwise indicated, check these
components in accordance with the
manufacturer's service schedule and according
to your engine.
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.
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 .
Practical information

188
Brake disc/drum wear
For information on checking
brake disc/drum 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. 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!
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.
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® containing urea,
a catalytic converter converts up to 85%
of nitrogen oxides (NOx) into nitrogen and
water, which are harmless to health and the
environment.
Practical information

189
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 faulty, 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 travelling the distance
of 685

miles (1,100 km), a system will be
triggered automatically to prevent the
engine from 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 the associated
alerts, refer to the corresponding section.
Freezing of the AdBlue
®
AdBlue® freezes at temperatures below
around -11°C.
The SCR system includes a heater for the
AdBlue
® tank, allowing you to continue
driving in very cold conditions.
Supply of AdBlue®
It is recommended that the AdBlue® is
topped up as soon as the first alert is
issued indicating that the reser ve level has
been reached.
In order to ensure that the SCR system
operates correctly:
-

U

se only AdBlue
® fluid that meets the
ISO 22241 standard.
-

N

ever transfer AdBlue
® to another
container: it would lose its purity.
-

N

ever dilute AdBlue
® with water.
You can obtain AdBlue
® from a PEUGEOT
dealer or a qualified workshop. You can also visit a ser vice station
equipped with AdBlue
® pumps specially
designed for passenger vehicles (for those
versions with access to the AdBlue
® tank
via the fuel filler flap).
Never top up from an AdBlue
® dispenser
reserved for heavy goods vehicles.
Recommendations on
storage
AdBlue® freezes at about -11°C and
deteriorates above 25°C. It should be stored in
a cool place and protected from direct sunlight.
Under these conditions, the fluid can be kept
for at least a year.
If the additive has frozen, it can be used once it
has completely thawed out.
Never keep AdBlue
® containers in your
vehicle.
Precautions for use
AdBlue® is a urea-based solution. This liquid
is non-flammable, colourless and odourless
(when kept in a cool place).
