The system adapts its gear change
recommendation according to the
driving conditions (slope, load, etc.)
and the demands of the driver (power,
acceleration, braking, etc.).
The system never suggests:
-
e
ngaging first gear,
-
enga

ging reverse gear.
-

ging a lower gear.
On vehicle fitted with a manual gearbox,
the arrow may be accompanied by the
gear recommended.
Hill start assist
System which keeps your vehicle stationary
for a short time (approximately two seconds)
when starting on a gradient, the time it takes
to move your foot from the brake pedal to the
accelerator pedal.
It is only active when:
-

t
he vehicle is completely stationary, with
your foot on the brake pedal,
-

c
ertain conditions of gradient are met,
-

t
he driver's door is closed.
The hill start assist system cannot be
deactivated. Do not leave the vehicle while it is being
held temporarily in the hill start assist
phase.
If you need to leave the vehicle with the
engine running, apply the parking brake
manually then ensure that the parking
brake warning lamp is showing fixed on
the instrument panel.
Operating fault
On an ascending slope, with the vehicle
stationar y, the vehicle is held for a shor t
time when you release the brake pedal.
With a manual gearbox
, if you are in first gear
or in neutral.
With an automatic gearbox , if you are in D
or M .
With an electronic gearbox , if you are in D.On a descending slope, with the vehicle
stationary and reverse gear engaged, the
vehicle is held for a shor t time when you
release the brake pedal.
If a fault in the system occurs, this warning
lamp comes on accompanied by a message.
Contact a CITROËN dealer or a qualified
workshop to have the system checked.
Stop & Start
The Stop & Start system puts the engine
t emporarily into standby – STOP mode – during
stops in traffic (red lights, traffic jams, etc.). The
engine restarts automatically – START mode –
as soon as you want to move off.
The restart takes place instantly, quickly and
silently.

emissions as well as the noise level when
stationary.

Time counter of the Stop & Star t.
(minutes/seconds or hours/minutes) If your vehicle is fitted with this system, a time
counter calculates the sum of the periods in
STOP mode during a journey.
It resets to zero every time the ignition is
switched on.
For your comfort, during parking
manoeuvres, STOP mode is not available
for a few seconds after coming out of
reverse gear.
The Stop & Start system does not affect
the functionality of the vehicle, such as for
example, braking, power steering, etc.
Never refuel with the engine in STOP
mode; you must switch off the ignition with
the "START/STOP" button.

Deactivation/Reactivation
In certain circumstances, such as the need
to maintain the temperature in the passenger
compartment, it may be useful to deactivate the
Stop & Start system.
The system can be deactivated at any time,
once the ignition is switched on.
If the engine is in STOP mode, it then restarts.
The Stop & Start system is reactivated
automatically every time the ignition is switched
on.

Opening the bonnet
Before doing anything under the bonnet,
deactivate the Stop & Start system to
avoid any risk of injury resulting from an
automatic change to START mode. Driving on flooded roads
Before driving in a flooded area, it is
strongly recommended that you deactivate
the Stop & Start system.
For more information on Driving
recommendations
, particularly on
flooded roads, refer to the corresponding
section.
Operating fault
In the event of a fault with the
system, this warning lamp flashes in
the instrument panel.
Have it checked by a CITROËN dealer or a
qualified workshop.
In the event of a fault in STOP mode, the
vehicle may stall.
All of the instrument panel warning lamps come
on.
It is then necessary to switch off the ignition,
then restart the engine. Depending on the version, an alert
message may also be displayed, asking
you to change to neutral ( N) and to press
the brake pedal.
You must switch off the ignition, then start
the engine again.

cruise setting or lower the cruise setting.
3. Set the current speed of the vehicle as the
cruise setting or raise the cruise setting.
4. Cruise control Pause/Resume.

Tyre pressures should be checked when
the tyres are "cold" (vehicle stopped for
1 hour or after a journey of less than
6 miles (10 km) at moderate speeds).
Other wise (when hot), add 0.3 bar to the
pressures shown on the label.

Do not rely on a simple visual check. F

I

one in the temporary puncture repair kit),
check the pressures of the four tyres when
cold. If it is not possible to make this check
immediately, drive carefully at reduced
speed.
or
F
I
n the event of a puncture, use the
temporary puncture repair kit or the spare
wheel (depending on equipment).
The warning remains active until the
system is reinitialised.
Reinitialisation
The system must be reinitialised after any
adjustment to the pressures of one or more
tyres, and after changing one or more wheels. Before reinitialising the system, ensure
that the pressures of the four tyres
are correct for the conditions of use
of the vehicle and conform to the
recommendations on the tyre pressure
label.
The under-inflation alert can only be relied
on if the reinitialisation of the system has
been done with the pressures in the four
tyres correctly adjusted.
The under-inflation detection system
does not give a warning if a pressure is
incorrect at the time of reinitialisation.
Reinitialisation of the system is done via the
touch screen, with the ignition on and the
vehicle stationary .
F I n the Driving/Vehicle menu,
select the " Driving functions "
tab, then " Reset under-
inflation detection ".

The reinitialisation is confirmed by the display
of a message and an audible signal.
Snow chains
The system does not have to be
reinitialised after fitting or removing snow
chains.

If your vehicle is fitted with Stop & Start,
never refuel with the engine in STOP
mode; you must switch off the ignition
using the key, or the START/STOP button
if your vehicle has
K
eyless Entry and
Starting.
Fuel cut- of f
Your vehicle is equipped with a safety device
which cuts off the fuel supply in the event of a
collision.
Misfuel prevention
(Diesel)
(Depending on the country of sale.)
Mechanical device which prevents filling the
tank of a Diesel vehicle with petrol. It helps
avoid the risk of engine damage that can result
from filling with the wrong fuel.
Operation
It remains possible to use a fuel can to fill
the tank.
In order to ensure a good flow of fuel,
do not place the nozzle of the fuel can in
direct contact with the flap of the misfuel
prevention device and pour slowly. Travelling abroad
As Diesel fuel pump nozzles may be
different in other countries, the presence
of the misfuel prevention device may make
refuelling impossible.
Not all Diesel vehicles are fitted with
misfuel protection, so before travelling
abroad, we recommend that you check
with the CITROËN dealer network whether
your vehicle is suitable for the fuel pumps
in the country in which you intend to travel.
When a petrol filler nozzle is introduced into the
Diesel tank, it comes into contact with the flap.
The system remains closed and prevents filling.
Do not persist but introduce a Diesel type
filler nozzle.
Snow chains
In wintry conditions, snow chains
improve traction as well as the
behaviour of the vehicle when
braking.
Snow chains must be fitted only to the
front wheels. They must never be fitted to
"space-saver" type spare wheels.
Take account of the legislation in force in
your country on the use of snow chains
and the maximum authorised speed.
