Eco-driving
Eco-driving
Eco-driving refers to a range of everyday
practices that allow the motorist to optimise
the vehicle's energy consumption (fuel and/or
electricity) and CO
2 emissions.
Optimise your use of the gearbox
With an automatic gearbox, favour automatic
mode. Do not depress the accelerator pedal
heavily or suddenly.
The gear shift indicator prompts you to engage
the most suitable gear. Whenever this indication
is displayed on the instrument panel, follow it
straight away.
With an automatic gearbox, this indicator
appears only in manual mode.
Drive smoothly
Maintain a safe distance between vehicles, use
engine braking rather than the brake pedal and
press the accelerator gradually. These practices
help to save on energy consumption, reduce
CO
2 emissions and decrease general traffic
noise.
Favour the use of the "Eco" driving mode by
selecting it using the "DRIVE MODE" control.
With an EAT8 gearbox, with the gear selector in
mode
D, and except in Sport mode, favour "free-
wheeling" by gradually and fully lifting your foot
off the accelerator pedal in order to save fuel.
When the traffic is flowing smoothly, select the
cruise control.
Control the use of electrical equipment
Before moving off, if the passenger compartment
is too warm, ventilate it by opening the windows
and air vents before using the air conditioning.
At speeds above 31
mph (50 km/h), close the
windows and leave the air vents open.
Consider using equipment that can help keep
the temperature in the passenger compartment
down (e.g.
sunroof blind, window blinds).
Unless automatically regulated, switch off the air
conditioning as soon as the desired temperature
has been reached.
Switch off the demisting and defrosting functions,
if they are not managed automatically.
Switch off the heated seat as soon as possible.
Adapt your use of the headlamps and/or
foglamps to the level of visibility, in accordance
with current legislation in the country in which
you are driving.
Avoid running the engine before moving off,
particularly in winter (other than in severe wintry
conditions: temperature below -23°C). The
vehicle will warm up much faster while driving.
As a passenger, avoid connecting your
multimedia devices (e.g.
film, music, video
game) to help reduce the consumption of energy.
Disconnect all portable devices before leaving
the vehicle.
Limit the causes of excess consumption
Spread loads throughout the vehicle. Place the
heaviest items in the boot as close as possible to
the rear seats. Limit the loads carried in the vehicle and
minimise wind resistance (e.g.
roof bars, roof
rack, bicycle carrier, trailer). Preferably, use a
roof box.
Remove roof bars and roof racks after use.
At the end of winter, remove snow tyres and refit
summer tyres.
Comply with the servicing instructions
Check tyre pressures regularly, with the tyres
cold, referring to the label in the door aperture on
the driver's side.
Carry out this check in particular:
–

before a long journey
.
–

at each change of season.
–


after a long period out of use.
Do not forget the spare wheel and, where
applicable, the tyres on your trailer or caravan.
Have your vehicle serviced regularly (e.g.

engine
oil, oil filter, air filter, passenger compartment
filter, etc.). Observe the schedule of operations in
the manufacturer's service schedule.
With a BlueHDi Diesel engine, if the SCR system
has a fault, your vehicle will emit pollution. Visit
a PEUGEOT dealer or a qualified workshop
as soon as possible to restore your vehicle's
nitrogen oxide emissions to legal levels.
When filling the fuel tank, do not continue after
the third cut-out of the nozzle, to avoid overflow.
You will only see the fuel consumption of your
new vehicle settle down to a consistent average
after the first 1,900 miles (3,000 kilometres).
Optimising the driving range
(rechargeable hybrid vehicles)
Connect the vehicle as soon as possible.
Favour the ECO zone of the power indicator by
driving smoothly and at a steady speed.
Anticipate slowing down as much as possible
and, if possible, favour decelerations with
regenerative braking mode activated (power
indicator in the CHARGE zone).
With the vehicle connected, carry out
temperature pre-conditioning before setting off.
To optimise consumption during a journey:
► Programme a destination in the vehicle’s
GPS navigation system.
► Select the Hybrid driving mode.
► Make sure that the battery charge level is
close to maximum.
► Do not use the e-Save function while driving.
► Use the heating/air conditioning system
wisely.

Avoid prolonged contact of used oil or fluids with the skin.
Most of these fluids are harmful to health and
very corrosive.
Do not discard used oil or fluids into
sewers or onto the ground.
Empty used oil into the containers reserved
for this purpose at a PEUGEOT dealer or a
qualified workshop.
Engine oil
The level is checked, with the engine having been switched off for at least 30
minutes and on level ground, either using the oil
level indicator in the instrument panel when the
ignition is switched on (for vehicles equipped
with an electric gauge), or using the dipstick.
It is normal to top up the oil level between two
services (or oil changes). It is recommended
that you check the level, and top up if necessary,
every 3,000 miles (5,000 km).
In order to maintain the reliability of the
engine and emissions control system,
never use additives in the engine oil.
Checking using the dipstick
For the location of the dipstick, please refer
to the illustration of the corresponding engine
compartment.
►

Grasp the dipstick by its coloured grip and
pull it out completely

.
►

Wipe the end of the dipstick using a clean,
lint-free cloth.


► Reinsert the dipstick and push fully down,
then pull it out again to visually check the oil
level: the correct level is between marks A
(max)
and B (min).
Do not start the engine if the level is:
–

above mark
A: contact a PEUGEOT dealer or
a qualified workshop.
–

below mark B

: top up the engine oil
immediately.
Oil grade
Before topping up or changing the
engine oil, check that the oil is suitable
for your engine and complies with the
recommendations in the service schedule
supplied with the vehicle (or available
from your PEUGEOT dealer or qualified
workshop).
Use of non-recommended oil may invalidate
your warranty in the event of engine failure.
Topping up the engine oil level
For the location of the engine oil filler cap, please
refer to the corresponding engine compartment
illustration.
►

Add oil in small quantities, avoiding any spills
on engine components (risk of fire).

176
Practical information
► Wait a few minutes before checking the level
again using the dipstick.
►
T
op up the level if necessary.
►

After checking the level, carefully screw the
oil filler cap back on

and replace the dipstick in
its tube.
The oil level indication displayed on the instrument panel when the ignition is
switched on is not valid for 30 minutes
following an addition of oil.
Brake fluid
The level of this fluid should be close to the "MAX" mark. If not, check the brake
pads for wear.
To know how often the brake fluid should be
replaced, refer to the manufacturer's servicing
schedule.
Clean the cap before removing it to refill.
Use only DOT4 brake fluid from a sealed
container.
Engine coolant
It is normal to top up this fluid between
two services.
The check and top-up must only be done with
the engine cold.
A level of coolant that is too low risks causing
major damage to the engine; the coolant level
must be close to the "MAX" mark without ever
going above it.
If the level is close to or below the " MIN" mark, it
is essential to top it up.
When the engine is hot, the temperature of the
coolant is regulated by the fan.
As the cooling system is pressurised, wait at
least one hour after switching off the engine
before carrying out any work.
In order to avoid the risk of scalding if 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.
Screenwash fluid
Top up to the required level when necessary.
Fluid specification
The fluid must be topped up with a pre-mixed
product.
In winter (temperatures below zero), a fluid
containing an anti-freeze agent which is
appropriate for the temperature conditions
must be used in order to protect the system's
components (pump, tank, ducts, jets).
Filling with pure water is prohibited in all
circumstances (risk of freezing,
limescale, etc.).
Diesel fuel additive (Diesel
with particle filter)
On reaching the minimum level in the
particle filter additive tank, this warning
lamp comes on fixed, accompanied by an
audible signal and a warning message.
Topping up
The topping up of this additive must be carried
out quickly.
Go to a PEUGEOT dealer or a qualified
workshop.
AdBlue® (BlueHDi)
An alert is triggered when the reserve level is
reached.
For more information on the Indicators and in
particular the AdBlue range indicators, refer to
the corresponding section.
To avoid the vehicle being immobilised in
accordance with regulations, you must top up the
AdBlue tank.
For more information on AdBlue
® (BlueHDi),
and in particular the supply of AdBlue, refer to
the corresponding section.
Checks
Unless otherwise indicated, check these
components in accordance with the
manufacturer's service schedule and according
to your engine.
Otherwise, have them checked by a PEUGEOT
dealer or a qualified workshop.
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.
12 V battery
The battery does not require any maintenance.
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 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.
Passenger compartment

Practical information
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.
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.
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!
Driving with worn or damaged tyres reduces the
braking and road holding performance of the
vehicle. Regularly check the condition of the
tyres (tread and sidewalls) and rims as well as
the presence of the valve caps.
When the wear indicators no longer appear set
back from the tread, the depth of the grooves is
less than 1.6 mm; replace the tyres as soon as
possible.
Using different size wheels and tyres from those
specified can affect the lifetime of tyres, wheel
rotation, ground clearance, 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.
Always mark the direction of rotation on the tyres
that will be stored when fitting winter or summer
tyres. Store them in a cool, dry place and away
from direct exposure to the sun's rays.
Winter or 4-seasons tyres can be
identified by this symbol on their
sidewalls.
Shock absorbers
It is not easy for drivers to detect when
shock absorbers are worn. Nevertheless,
the shock absorbers have a major impact on
road holding and braking performance. For your safety and driving comfort, it is
important to have them regularly checked by a
PEUGEOT dealer or a qualified workshop.
Timing and accessory kits
The timing and accessory kits are used
from the time the engine is started until it
is switched off. It is normal for them to wear over
time.
A
faulty timing or accessory kit can damage
the engine, rendering it unusable. Observe the
recommended replacement frequency, stated in
distance travelled or time elapsed, whichever is
reached first.
AdBlue® (BlueHDi)
To respect the environment and ensure compliance with the Euro 6 standard, without
adversely affecting the performance or fuel
consumption of its Diesel engines, PEUGEOT
has taken the decision to equip its vehicles with
a system that combines SCR (Selective Catalytic
Reduction) with a Diesel Particle Filter (DPF) for
the treatment of exhaust gases.
SCR system
Using a liquid called AdBlue® that contains
urea, a catalytic converter turns up to 85% of
the nitrogen oxides (NOx) into nitrogen and
water, which are harmless to health and the
environment.

180
Practical information
for a few hours to allow the top-up to be carried
out.
Never pour the AdBlue® into the Diesel
fuel tank.
If any AdBlue® is splashed, or if there are
any spillages on the bodywork, 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
an AdBlue breakdown, you must wait
about 5
minutes before switching on the
ignition, without opening the driver's door,
unlocking the vehicle or bringing the
electronic key into the passenger
compartment.
Switch on the ignition, then wait for 10
seconds before starting the engine.
►

Press the "
START/STOP" button to switch off
the engine.


► Turn the blue cap of the AdBlue® tank anti-
clockwise and remove it.
►

With a container of

AdBlue
®: after checking
the expiry date, read the instructions on the
label carefully before pouring the contents of the
container into the vehicle's AdBlue tank.
►

With an


AdBlue® pump: insert the nozzle and
fill the tank until the nozzle automatically cuts
out.
In order not to overfill the AdBlue® tank:
–
Add between 10 and 13 litres using
AdBlue® containers.
–
Stop after the nozzle’ s first automatic cut-
out, if you are refilling at a service station.
The system only registers AdBlue
® top-ups of
5

litres or more.
If the AdBlue® tank is completely empty
– which is confirmed by the message
“Top up

AdBlue: Starting impossible ” – it is
essential to add at least 5 litres.
Free-wheeling
In certain situations, it is necessary to put the
vehicle into free-wheeling mode (e.g. towing, on
a rolling road, automatic car wash (Wash mode),
rail or sea transport).
The procedure varies according to the type of
gearbox and parking brake.
/
Release procedure
► With the vehicle stationary and the engine
running, select mode N and switch off the
ignition.
Within 5
seconds:
►

Switch on the ignition again.
►


While depressing the brake pedal, move the
push selector forwards or backwards to confirm
mode

N.
►

While depressing the brake pedal, press the
control to release the parking brake.
►


Release the brake pedal, switch off the
ignition.
If the 5-second time limit is exceeded, the
gearbox engages mode P

; it is then necessary to
restart the procedure.
Reverting to normal operation
► While depressing the brake pedal, restart the
engine.
Keyless Entry and Start
You must not depress the brake pedal
while switching the ignition on again, then
switching it off. If you do, the engine will start,
requiring you to restart the procedure.
Advice on care and maintenance
General recommendations
Observe the following recommendations to avoid
damaging the vehicle.
Exterior
Never use a high-pressure jet wash in
the engine compartment - risk of
damaging the electrical components!
Do not wash the vehicle in bright sunshine or
extremely cold conditions.
When washing the vehicle in an
automatic roller-brush car wash, be sure
to lock the doors and, depending on version,
move the electronic key away and deactivate
the "hands-free" function (Hands-Free
Tailgate Access).
When using a pressure washer, keep the jet
nozzle at a minimum distance of 30 cm from
the vehicle (particularly when cleaning areas
containing chipped paint, sensors or seals).
Promptly clean up any stains containing
chemicals liable to damage the vehicle's
paintwork (including tree resin, bird
droppings, insect secretions, pollen and tar).
Depending on the environment, clean the
vehicle frequently to remove salty deposits
(in coastal areas), soot (in industrial areas)
