Energy economy mode
System which manages the duration of use of
certain functions to conser ve a sufficient level
of charge in the battery.
After the engine has stopped, you can still use
functions such as the audio and telematics
system, windscreen wipers, dipped beam
headlamps,
courtesy lamps, etc. for a
maximum combined duration of about forty
minutes.
Switching to this mode
A message appears in the instrument panel
screen indicating that the vehicle has switched
to economy mode and the active functions are
put on standby.
If a telephone call is being made at this
time, it will be maintained for around
10
minutes with the Bluetooth hands-free
kit of your audio system.
Exiting the mode
These functions will be automatically restored
the next time the vehicle is used.
In order to restore the use of these functions
immediately, start the engine and let it run:

System which manages the use of certain
functions according to the level of charge
remaining in the battery.

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).

Practical information

In the event of contact with the skin, wash the
affected area with soap and water. In the event
of contact with the eyes, wash (irrigate) the
eyes with large amounts of water or with an eye
wash solution for at least 15 minutes. If you feel
a persistent burning sensation or irritation, get
medical attention.
If swallowed, immediately wash out the mouth
with clean water and then drink plenty of water.
In certain conditions (at high temperature,
for example), the risk of release of ammonia
cannot be excluded: do not inhale the vapour.
Ammonia has an irritant effect on mucous
membranes (eyes, nose and throat).
Keep AdBlue
® in its original container and
out of the reach of children.
Procedure
Before starting the top up procedure, ensure
that the vehicle is parked on a flat and level
sur face.
In winter, check that the temperature of the
vehicle is above -11°C. If not, due to freezing,
the AdBlue
® cannot be poured into the tank.
Park your vehicle somewhere warmer for a few
hours before topping up. In the event of an AdBlue
® breakdown,
confirmed by the message "Add AdBlue:
Starting impossible", you must top up with
at least 5

litres.
Never pour AdBlue
® into the Diesel fuel
tank.
For the specifics associated with the
access configuration for the AdBlue
® tank
(via the boot or via the fuel filler flap), refer
to the descriptions given in detail further
on.
If any AdBlue
® is splashed, or if there are
any spillages on the side of the body, rinse
immediately with cold water or wipe with a
damp cloth.
If the fluid has crystallised, clean it off
using a sponge and hot water.
Important: in the event of a top-up after a
breakdown because of a lack of AdBlue,
you must wait around 5
minutes before
switching on the ignition, without opening
the driver’s door, locking the vehicle,
introducing the key into the ignition
switch, or introducing the key of the

K

eyless Entr y and Star ting system into
the passenger compartment.
Switch on the ignition, then wait for
10


seconds before starting the engine.

Access to the AdBlue® tank
via the boot
Filling the AdBlue® tank is an operation
included in every routine ser vice on your
vehicle by a PEUGEOT dealer or a qualified
workshop.
Nevertheless, given the capacity of the tank, it
may be necessary to top up the fluid between
ser vices, as soon as an alert (warning lamps
and a message) indicates it.
You can go to a PEUGEOT dealer or a qualified
workshop.
If you intend to do the topping-up yourself,
read the following procedure carefully.

topping up.
