Driving
6Starting/switching off the
engine
The electronic key must be present in the passenger compartment.
If the electronic key is not detected, a
message is displayed.
Move the electronic key so that the engine
can be started or switched off.
If there is still a problem, refer to the "Key
not detected - Back-up starting or Back-up
switch-off" section.
Starting

► Select mode P or N on the automatic
gearbox, then depress the brake pedal.
►

Press the "
START/STOP" button while
maintaining pressure on the pedal until the
engine starts.
Diesel engines
In negative temperatures and/or when the
engine is cold, starting takes place only after the
preheating warning lamp goes out.
If this warning lamp comes on after
pressing the " START/STOP" button:
►

Keep the pedal fully depressed and do not
press the "

START/STOP" button again until the
engine is running.
In all circumstances, if one of the starting
conditions is not met, a message is displayed.
In some circumstances, a message indicates
that it is necessary to turn the steering wheel
while pressing the " START/STOP" button to
assist unlocking of the steering column.
Petrol engines
With Petrol engines, after a cold start,
pre-heating the catalytic converter can cause
noticeable engine vibrations, for anything up
to 2

minutes (accelerated idle speed).
Starting rechargeable hybrid
vehicles
► Fully depress the brake pedal and press
the START/STOP button for approximately 2
seconds.
► Keep you r foot on the pedal until this
indicator lamp comes on, indicating the
activation of the rechargeable hybrid system
(confirmed by an audible signal).
To exit Park mode, wait for the READY indicator lamp to come on.
By default, the system starts in Electric mode.
Depending on certain parameters (battery
charge level or outside temperature), the system
determines whether it is necessary to start the
petrol engine.
It is possible to change the driving mode at any
time using the mode selector.
When the vehicle starts in electric mode,
it makes no noise.
Pay particular attention to pedestrians and
cyclists who may not hear the vehicle coming
despite the pedestrian horn.
Switching off
► Immobilise the vehicle using the parking
brake.
►

Select mode
P on the automatic gearbox.
►

Press the "
START/STOP" button.
►

For rechargeable hybrid vehicles, before
leaving the vehicle, check that the READY


indicator lamp is switched off.
In some circumstances, it is necessary to turn
the steering wheel to lock the steering column.
On certain versions with an automatic gearbox
(EAT8), the steering column does not lock, but
the gearbox locks in mode P.
If the vehicle is not immobilised, the
engine will not stop.

Practical information

► To open the filler flap, press the flap opening
button for more than 2 seconds or, with the
vehicle unlocked, press the rear of the filler flap
(depending on version).
Rechargeable hybrid vehicles
After pressing the button on the
dashboard, the filler flap may not open for
several minutes. A sound is emitted when the
filler flap opens.
If the flap becomes stuck, press and hold
the button on the dashboard for more than
3

seconds.


► Select a pump that delivers the correct fuel
type for the vehicle's engine (see a reminder
label on the inside of the filler flap).
►

T
urn the filler cap to the left, remove it
and place it on its support on the filler flap
(depending on version).
►

Insert the filler nozzle and push it in as far as
possible before starting to refuel (to minimise the
risk of splashing).
►


Fill the tank.
Do not continue after the nozzle’

s third cut-
out. Doing so may cause malfunctions.
►

Put the filler cap back in place and turn it to
the right (depending on version).
►


Push the fuel filler flap to close it.
The vehicle is fitted with a catalytic converter,
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, allowing only
unleaded petrol nozzles to be inserted.
If you have put in the wrong fuel for
the vehicle, you must have the fuel
tank drained and filled with the correct fuel
before starting the engine.
Misfuel prevention (Diesel)
(Depending on country of sale.)
This mechanical device prevents filling the tank
of a Diesel vehicle with petrol.
Located in the filler neck, the misfuel prevention
device is visible when the filler cap is removed.

Practical information
7Brake 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.
The AdBlue® is contained in a special
tank holding about 17 litres.
Its capacity allows a driving range of
approximately 3,900
miles (6,500 km),
which
may vary considerably depending on your
driving style.
An alert system is triggered once the reserve
level is reached: it is then possible to drive for a
further 1,500 miles (2,400

km) before the tank is
empty and the vehicle is immobilised.
For more information on the Warning
and indicator lamps and the associated
alerts, or the Indicators, please refer to the
corresponding sections.
