Eco-driving
Eco-driving is a range of everyday practices
that allow the motorist to optimise their fuel
consumption and CO
2 emissions.
Optimise the use of your gearbox
With a manual gearbox, move off gently
and change up without waiting. During
acceleration, change up early.
With an automatic gearbox, give preference
to automatic mode and avoid pressing the
accelerator pedal heavily or suddenly.
The gear efficiency indicator invites you to
engage the most suitable gear: as soon as the
indication is displayed in the instrument panel,
follow it straight away.
For vehicles fitted 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
progressively. These practices contribute
towards a reduction in fuel consumption and
CO
2 emissions and also help reduce the
background traffic noise.
If your vehicle has cruise control, make use of
the system at speeds above 25 mph (40 km/h)
when the traffic is flowing well.
Control the use of your 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.
Above around 30 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 (sunroof blind and window
blinds...).
Unless it has automatic regulation, switch off
the air conditioning as soon as the desired
temperature has been reached. Switch off the headlamps and front foglamps
when the ambient light level does not require
their use.
Avoid running the engine before moving off,
particularly in winter; your vehicle will warm up
much faster while driving. Switch off the demisting and defrosting
controls, if these are not automatically
managed.
Switch off the heated seat as soon as possible.
As a passenger, if you avoid connecting your
multimedia devices (film, music, video game
etc.), you will contribute towards limiting the
consumption of electrical energy, and so of
fuel.
Disconnect your portable devices before
leaving the vehicle.

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

A few definitions…
Range
(miles or km)
The distance which can still be
travelled with the fuel remaining
in the tank (related to the average
fuel consumption over the last few
miles (kilometres) travelled).
This value may fluctuate if a change
of driving style or terrain results in a
significant change in the current fuel
consumption.
Dashes are displayed when the range falls
below around 20 miles (30km).
After filling with at least 5 litres of fuel, the
range is recalculated and is displayed if it
exceeds around 60 miles (100 km).
If dashes instead of figures continue to be
displayed when driving, contact the dealer
network or a qualified workshop.
Current fuel consumption
(mpg or l/100 km or km/l) Calculated over the last few
seconds.
This function is only displayed above
around 20
mph (30 km/h).
Average fuel consumption
(mpg or l/100 km or km/l)Calculated since the last trip
computer reset.
Average speed
(mph or km/h)Calculated since the last trip
computer reset.
Distance travelled

Recalling a stored position
Ignition on or engine running
F Press button 1 or 2 to recall the corresponding position. An audible signal
indicates the completion of the adjustment.
You can interrupt the current movement by
pressing button M , 1 or 2 or by using one
of the seat controls.
A stored position cannot be recalled while
driving.
Recalling stored positions is deactivated
45 seconds after switching off the ignition.
Heated seats control
F Use the adjustment dial, placed on the side of each front seat, to switch on and select
the level of heating required:
0 Of f.
1 Low.
2 Medium.
3 High.
With the engine running, the front seats can be
heated separately. Do not use the function when the seat is
not occupied.
Reduce the intensity of the heating as
soon as possible.
When the seat and passenger
compartment have reached an adequate
temperature, you can stop the function;
reducing the consumption of electrical
current reduces fuel consumption.Prolonged use at the highest setting is
not recommended for those with sensitive
skin.
There is a risk of burns for people whose
perception of heat is impaired (illness,
taking medication, etc.).
There is a risk of overheating the system if
material with insulating properties is used,
such as cushions or seat covers.
Do not use the system:
-

i
f wearing damp clothing,
-

i
f child seats are fitted.
To avoid breaking the heating element in
the seat:
-

d
o not place heavy objects on the seat,
-

d
o not kneel or stand on the seat,
-

d
o not place sharp objects on the seat,
-

d
o not spill liquids onto the seat.
To avoid the risk of short-circuit:
-

d
o not use liquid products for cleaning
the seat,
-
n

ever use the heating function when
the seat is damp.

Malfunction
When the ignition is on, a message appears
in the instrument panel screen to indicate a
gearbox fault.
In this case, the gearbox switches to back-up
mode and is locked in 3rd gear. You may feel a
substantial jolt when changing from P to R and
from N to R. This will not cause any damage to
the gearbox.
Do not exceed around 60 mph (100 km/h), local
speed restrictions permitting.
Have it checked by a network dealer or a
qualified workshop.There is a risk of damage to the gearbox:
-

i
f you press the accelerator and brake
pedals at the same time,
-

i
f you force the selector from position P
to another position when the battery is
flat.
To reduce fuel consumption when
stationary for long periods with the
engine running (traffic jam...), position
the gear selector at N and apply the
parking brake, unless it is programmed
in automatic mode.
Gear efficiency indicator
(Depending on engine.) System which reduces fuel consumption by
recommending the most appropriate gear.
Operation
Depending on the driving situation and your
vehicle's equipment, the system may advise
you to skip one (or more) gear(s). You can
follow this instruction without engaging the
intermediate gears.
Gear shift recommendations should not be
considered obligatory. The configuration of the
road, the amount of traffic and safety remain
determining factors when choosing the best
gear. The driver thus remains responsible
for deciding whether to follow or ignore the
system's instructions.
This function cannot be deactivated.
With an automatic gearbox, the system is
only active in manual mode. The system adapts its gear change
recommendation according to the
driving conditions (slope, load,...) and
the demands of the driver (power,
acceleration, braking,...).
The system never suggests:
-
e

ngaging first gear,
-
enga

ging reverse gear,
-
enga

ging a lower gear.
Example:
-
Y
ou are in third gear.
-
Y
ou press the accelerator pedal.
-
T
he system may suggest that you engage a
higher gear.
The information appears in the instrument
panel in the form of an arrow. With a manual gearbox, the arrow may be
accompanied by the gear recommended.

Stop & Start
The Stop & Start system puts the engine
t emporarily into standby – STOP mode – during
stops in the traffic (red lights, traffic jams,...).
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
The " ECO" warning lamp comes on in
the instrument panel and the engine
goes into standby automatically:
- with a manual gearbox , at speeds below
12 mph (20 km/h) or when the vehicle is
stationary with the PureTech 130 petrol and
BlueHDi 115 and 120 Diesel versions, when
you place the gear lever in neutral and you
release the clutch pedal,
-

W
ith an automatic gearbox , when the
vehicle is stationary and when you press
the brake pedal or put the gear selector in
position N . If your vehicle is fitted with this
system, a time counter calculates
the time spent in STOP mode
during a journey. It resets to
zero every time the ignition is
switched on with the key or the
"START/STOP" button.
STOP mode does not affect the operation
of vehicle systems such as braking, power
steering...
Never refuel with the engine in STOP
mode; you must switch off the ignition with
the key or the "START/STOP" button.
Special cases: STOP mode not
available
STOP mode is not activated when:
- t he vehicle is on a steep slope (uphill or
downhill),
-

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 (with the
key or the "START/STOP" button),
-

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,
-
c
ertain special conditions (battery charge,
engine temperature, braking assistance,
exterior temperature, etc.) require the
engine to be running to assure control of a
system.
In this case, the " ECO" warning
lamp flashes for a few seconds then
goes off.
This operation is perfectly normal.
Going into engine START mode
The ECO warning lamp goes off and
the engine starts automatically:
-

w

ith a manual gearbox , when you fully
depress the clutch pedal,
-

w

ith an automatic gearbox:
•

g

ear selector in position D or M , when
you release the brake pedal,
•
