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 lifting your foot fully 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).

Indicators
Service indicator
The servicing information is expressed in terms
of distance (miles or kilometres) and time
(months or days).
The alert is given at whichever of these two
terms is reached first.
The servicing information is displayed in the
instrument panel. Depending on the version of
the vehicle:
–

The distance recorder display line indicates
the distance remaining before the next service
is due, or the distance travelled since it was due
preceded by the "-" sign.
–


An alert message indicates the distance
remaining, as well as the period before the next
service is due or how long it is overdue.
The value indicated is calculated according to the distance covered and
the time elapsed since the last service.
The alert may also be triggered close to a
due date.
Service spannerOn temporarily when the ignition is
switched on.
Between 620 and 1,860 miles (1,000 and 3,000
km) remain before the next service is due.
Fixed, when the ignition is switched on.
The next service is due in less than 620
miles (1,000 km).
Have your vehicle serviced very soon.
Service spanner flashingFlashing then fixed, when the
ignition is switched on.

Have your vehicle serviced as soon as possible.
Resetting the service indicator
The service indicator must be reset after each
service.
If you have serviced your vehicle yourself:
►

Switch the ignition off.




► Press and hold the button located on the end
of the lighting control stalk.
►

Without pressing the brake pedal, press the
ST

ART/STOP button once; a temporary display
window appears and a countdown begins.
►

When the display indicates =0

, release the
lighting control stalk button; the spanner symbol
disappears.
If you disconnect the battery following
this operation, lock the vehicle and wait
at least 5 minutes for the reset to be
registered.
Reminder of the servicing information
Servicing information is accessible using
the Settings > Vehicle application on the
touch screen.
►

Then select
Safety > Diagnostics.
Engine oil level indicator
(Depending on version)

19
Dashboard instruments
1On versions fitted with an electric gauge, the
engine oil level status is displayed on the
instrument panel for a few seconds when
the ignition is switched on, after the servicing
information, in the form of messages.
The level read will only be correct if the vehicle is on level ground and the engine
has been off for more than 30 minutes.
Low oil level
This is indicated by a message prompting you to
top up the level, accompanied by the lighting of
the Service warning lamp and an audible signal.
If a low oil level is confirmed by a check using
the dipstick, the level must be topped up to avoid
damage to the engine.
For more information on Checking levels, refer
to the corresponding section.
Oil gauge malfunction
This is indicated by the message " Oil level
measurement invalid" on the instrument panel.
Consult a PEUGEOT dealer or a qualified
workshop.
In the event of a malfunction of the
electric gauge, the oil level is no longer
monitored.
If the system is faulty, you must check the
engine oil level using the manual dipstick
located in the engine compartment.
For more information on Checking levels,
refer to the corresponding section.
Coolant temperature
indicator


With the engine running:
– In zone A, the temperature is correct.
–

In zone
B, the temperature is too high. The
associated warning lamp and the STOP
warning
lamp light up in red on the instrument panel,
accompanied by the display of a message and
an audible signal.
You must stop the vehicle as soon as it is
safe to do so.
Wait a few minutes before switching off the
engine.
After switching off the ignition, carefully open the bonnet and check the coolant
level.
For more information on Checking
levels, refer to the corresponding
section.
AdBlue® range indicators
(BlueHDi)
The Diesel BlueHDi engines are equipped with
a system that associates the SCR (Selective
Catalytic Reduction) emissions control system
and the Diesel particle filter (DPF) for the
treatment of exhaust gases. They cannot
function without AdBlue
® fluid.
When the level of AdBlue® falls below the
reserve level (between 1,500 and 0 miles (2,400
and 0

km)), a warning lamp lights up when
the ignition is switched on and an estimate
of the distance that can be travelled before
engine starting is prevented is displayed in the
instrument panel.
The engine starting prevention system required by regulations is activated
automatically once the AdBlue
® tank is empty.
It is then no longer possible to start the
engine until the minimum level of AdBlue
® has
been topped up.
Manual display of driving range
While the driving range is greater than
1,500 miles (2,400 km), it is not displayed
automatically.
Driving range information is accessible
using the Settings > Vehicle application
on the touch screen.
►

Then select
Safety > Diagnostics.
