Driving
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.
► With a manual gearbox, ideally put the gear
lever into neutral.
► With an automatic gearbox, ideally select
mode P or N.
► 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
(EAT6/EAT8), the steering column does not lock,
but the gearbox locks in mode P.
If the vehicle is not immobilised, the
engine will not switch off.
With the engine off, the braking and
steering assistance systems are also cut
off - risk of loss of control of the vehicle!
Never leave your vehicle with the
electronic key still inside.
will be switched off automatically after one
hour.
To switch the ignition back on, turn the key
to position 1 (Stop), then back to position 2
(Ignition on) .
Starting / Switching off the
engine with Keyless Entry
and Starting
The electronic key must be present in the
passenger compartment.
If it 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 the engine

► With a manual gearbox, place the gear lever
in neutral and depress the clutch pedal fully.
or
►

With an
automatic gearbox, select mode P
or N and press the brake pedal.
►

Press the "
START/STOP" button while
maintaining pressure on the pedal until the
engine starts.
For Diesel engines, when the temperature is
below zero and/or the engine is cold, starting
will only occur once the preheater warning lamp
is off.
If this warning lamp comes on after
pressing the " START/STOP" button:
►

Y

ou should keep the pedal fully depressed
and not press the "START/STOP" button again
until the engine is running.
If one of the starting conditions is not met, a
message is displayed.
In some circumstances, you are alerted by a
message that it is necessary to turn the steering
wheel while pressing the " START/STOP" button,
to help unlock the steering column.
With petrol engines , after a cold start,
preheating the catalytic converter can
cause noticeable engine vibrations for
anything up to 2 minutes while stationary with
the engine running (accelerated idle speed).
Starting rechargeable hybrid
vehicles
► Fully depress the brake pedal and press
the START/STOP button for approximately 2
seconds.
► Keep your 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.

Practical information
7Driving with worn or damaged tyres reduces the
braking and road holding performance of the
vehicle. It is recommended to regularly check the
condition of the tyres (tread and sidewalls) and
wheel rims as well as the presence of the valves.
When the wear indicators no longer appear set
back from the tread, the depth of the grooves is
less than 1.6 mm; it is essential to replace the
tyres.
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.
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
CITROËN dealer or a qualified workshop.
Timing and accessory kits
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, CITROËN
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 4,000
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.
Once the AdBlue® tank is empty, a device
required by law prevents the engine from
being restarted.
If the SCR system is faulty, the level of
emissions from the vehicle will no longer meet
the Euro 6 standard and the vehicle starts
polluting the environment.
In the event of a confirmed SCR system
malfunction, it is essential to visit a CITROËN
dealer or a qualified workshop. After 685
miles (1,100 km), a device is automatically
activated to prevent the engine from starting.
In both cases, a range indicator indicates
the distance that can be travelled before the
vehicle is stopped.
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® be topped
up as soon as the first alert is issued indicating
that the reserve level has been reached.
