HILL START ASSIST
This system (also called HHC - Hill Holder
Control), linked to the dynamic stability
control system, makes hill starts easier and
is activated in the following conditions:
- the vehicle must be stationary, engine running, foot on the brake,
- the gradient of the road must be steeper than 5%,
- uphill, the gearbox must be in neutral or in a gear other than reverse,
- downhill, reverse gear must be engaged.
The Hill Start Assist function is a driving
aid system. It is not an automatic vehicle
parking function or an automatic parking
brake. Operation
With the brake pedal and clutch pedal
pressed, from the time you release the brake
pedal you have approximately 2 seconds
before the vehicle starts to roll back and
without using the parking brake within which
to move off.
During the moving off phase, the function
is deactivated automatically, gradually
releasing the braking pressure. During
this phase, the characteristic noise of
mechanical release of the brakes may be
heard, indicating the imminent movement of
the vehicle.
Operating fault
If a malfunction of the system
occurs, this warning lamp comes
on accompanied by an audible
signal and confi rmed by a message
in the screen. Have the system checked by at
a CITROËN dealer or a qualifi ed workshop. Hill start assist is deactivated in the following
situations:
- when the clutch pedal is released,
- when the parking brake is applied,
- when the engine is switched off,
- when the engine stalls.

Starting and stopping
The Stop & Start system puts the engine
temporarily into standby - STOP mode -
during stops in the traffic (red lights, traffic
jams, or other...). The engine restarts
automatically - START mode - as soon as
you want to move off. The restart takes
place instantly, quickly and silently.
Perfect for urban use, the Stop & Start
system reduces fuel consumption and
exhaust emissions and offers the comfort
of complete silence when stationary.
STOP & START
Operation
Going into engine STOP mode
With the vehicle stationary, put the gear
lever into neutral, then release the clutch
pedal. - The "S" warning lamp comes on in the instrument
panel and the engine goes
into standby. Automatic stopping of the engine is
only possible after the vehicle has
exceed a speed of about 6 mph (10 km/h),
to avoid repeated stopping of the engine
when driving slowly.
Never leave your vehicle with out first
turning off the ignition with the key.
Never refuel with the engine
in STOP mode; you must switch
off the ignition with the key. Special cases: STOP mode
unavailable
The STOP mode is not invoked when:
- the system is initialising,
- the driver's door is open,
- the driver's seat belt is not fastened,
- the air conditioning is running,
- the heated rear screen is on,
- the windscreen wiper is on fast wipe,
- reverse gear is engaged, for a parking
manoeuvre,
- some special conditions (battery charge, engine temperature, particle
filter regeneration, braking assistance,
ambient temperature...) where the
engine is needed to assure control of
a system.
The "S" warning lamp flashes for
a few seconds, then goes off.
This operation is perfectly normal.

READY TO GO
Starting and stopping
Going into engine START mode - The "S" warning lamp goes off and the engine restarts.
If following an automatic restart in START
mode, the driver takes no action on the
the vehicle during the next 3 minutes, the
system stops the engine definitively. The
engine can then only be restarted using
the key. Special cases: START invoked
automatically
The START mode is invoked automatically
when:
- the vehicle's is free wheeling on a slope,
- the windscreen wiper is on fast wipe,
- the air conditioning is running,
- the engine has been stopped for around
3 minutes with Stop & Start,
- some special conditions (battery charge, engine temperature, braking assistance,
ambient temperature...) where the
engine is needed to assure control of
a system.
In this case, a message appears
in the instrument panel screen,
accompanied by the "S" warning
lamp, which flashes for a few
seconds, then goes off. Good practice
With a manual gearbox in STOP mode, if a
gear is engaged without fully depressing the
clutch pedal, restarting may not take place.
A warning lamp or message is displayed
in the instrument panel asking you to fully
depress the clutch pedal to allow restarting.
With the engine stopped in STOP mode,
if the driver unfasten's their seat belt and
opens a front door, the engine can only be
restarted using the ignition key. There is an
audible signal, accompanied by flashing of
the "S" warning lamp and, depending on
equipment, a message is displayed.
This operation is perfectly normal.
With the vehicle in gear, automatic engine
restarting is only allowed by fully depressing
the clutch pedal.

Deactivation
At any time, press the "A - OFF" switch to deactivate
the system.
Illumination of the switch warning lamp, accompanied
by a message in the instrument panel screen,
confi rms the the instruction has been registered.
If the system has been deactivated
in STOP mode, the engine restarts
immediately.
It is necessary to deactivate the Stop &
Start system if you want to allow
continuous operation of the air conditioning.
The switch warning lamp stays on.
Reactivation
Press the "A - OFF" switch again.
The system is active again; the switch
warning lamp going off and a message
in the instrument panel screen confirm
reactivation.
Operating fault
In the event of a fault with the
system, the Stop & Start system
is deactivated and this warning
lamp comes on, accompanied by a
message in the instrument panel screen .
Have it checked by a CITROËN dealer or a
qualified workshop.
In the event of an operating fault with STOP
mode, it is possible to restart the engine by
depressing the clutch pedal fully and putting
the gear lever into neutral.
Maintenance
Before working under the bonnet, you
must switch off the ignition with the
key to avoid any risk of injury resulting from
automatic operation of START mode.
This system requires a specific battery
with a special specification and technology
(reference numbers available from a
CITROËN dealer or a qualified workshop).
Fitting a battery not listed by CITROËN
introduces the risk of malfunction of
the system.
The Stop & Start system makes use
of advanced technology. Specialist
knowledge is needed for any work on the
system, which can only be assured by
CITROËN dealers. Refer to the "Quick help - Flat battery"
section.

AUTOMATIC ILLUMINATION
Activation
Turn the ring to this position.
Do not cover the sunshine sensor at
the top centre of the windscreen.
GUIDE-ME-HOME LIGHTING
Ignition off or key in the STOP position.
Within 2 minutes after switching off the
engine, position the ignition key in the STOP
position or remove it.
Pull the lighting stalk towards the steering
wheel.
The indicator lamp comes on in
the instrument panel.
Each action on the lighting stalk,
pulled towards the steering
wheel, prolongs the guide me home
lighting by 30 seconds up to approximately
3 minutes. When this time has elapsed, the
lamps are switched off automatically.
Deactivate this control by keeping the stalk
pulled towards the steering wheel for more
than 2 seconds. If your vehicle is fitted with this function:
when you leave your vehicle, the dipped
beam headlamps remain on for the selected
duration (when leaving a car park for
example).
You can adjust the sensitivity of the
sunshine sensor.
Refer to the "Technology on board -
Vehicle configuration" section.
If your vehicle is fitted with this function, the
dipped beam headlamps are switched on
automatically if the light is poor.
In fog or snow, the sunshine sensor may
detect sufficient light. Therefore, the lamps
will not be switched on automatically. If
necessary, you must switch on the dipped
beam headlamps manually.
They are switched off when the light returns
to a sufficient level.
LED DAYTIME RUNNING LAMPS
On starting the vehicle, in daylight the LED
daytime running lamps come on automatically.
If the sidelamps and headlamps are switched
on manually or automatically, the daytime
running lamps go off.
Programming
For countries where exterior lighting by
day is not a legal requirement, you can
activate or deactivate the function via the
configuration menu.
The lamps are switched off automatically
when the ignition is switched off.

SPEED LIMITER
"This is the selected speed which the driver
does not wish to exceed".
This selection is made with the engine
running while stationary or with the vehicle
moving. The minimum speed which can be
programmed is 20 mph (30 km/h).
The speed of the vehicle responds to the
pressure of the driver's foot as far as the
accelerator pedal point of resistance which
indicates that the programmed speed has
been reached. However, pressing the pedal beyond this
point of resistance to the floor permits
exceeding of the programmed speed. To
resume use of the limiter, simply reduce
the pressure on the accelerator pedal
gradually and return to a speed below that
programmed.
The operating actions may be carried out
when stationary, with the engine running,
or with the vehicle moving.
This speed limiter shows the status of the
system and the programmed speed in the
instrument panel screen:
System selected,

Ventilation
DEMISTING AND DEFROSTING
Manual mode
Direct the control to this air
distribution setting.
For faster and more effective
demisting and defrosting of
the windscreen: Defrosting the rear screen
and mirrors
Only operates when the engine
is running. Pressing this button
activates the rapid demisting-
defrosting of the rear screen and
door mirrors.
This function switches off automatically to
prevent excessive energy consumption. It
stops when the engine is switched off but
resumes when the engine is started again.
Pressing this button switches the function off.
- increase the air flow setting,
Returning to the exterior air
intake position permits renewal
of the air in the passenger
compartment.
Windscreen and side windows
The ventilation outlets located at the base
of the windscreen and the side vents for the
side windows increase the effectiveness
of the demisting and defrosting. Do not
obstruct these air outlets.
The pollen filter continuously and effectively
filters dust.
Air recirculation (which can be activated by
the driver or the passenger) isolates the
passenger compartment from the exterior
atmosphere. However, this position should
only be used temporarily, normal use is to
drive with the control positioned with the
exterior air intake open.
- move the exterior air intake
control temporarily to air
recirculation.
With Stop & Start, when the heated
rear screen is switched on, the STOP
mode is not available.
