Stopping the vehicle

Before switching off the engine, you can
engage position P
or N
to place the gearbox in
neutral.
In both cases, apply the parking brake to
immobilise the vehicle, unless it is programmed
to automatic mode.

If the lever is not in position P
, when the
driver's door is opened or approximately
45 seconds after the ignition is switched
off, there is an audible signal and a
message appears.


)
Return the lever to position P
;
the audible signal stops and the
message disappears.




Operating fault

When the ignition is on, the lighting of this
warning lamp, accompanied by an audible
signal and a message in the multifunction
screen, indicates a gearbox malfunction.
In this case, the gearbox switches to back-up
mode and is locked in 3rd gear. You may feel
a substantial knock when changing from P

to R
and from N
to R
. This will not cause any
damage to the gearbox.
Do not exceed 60 mph (100 km/h), local speed
restrictions permitting.
Have it checked by a CITROËN dealer or a
qualified workshop.
This warning lamp may also come on if a door
is opened.
You risk damaging the gearbox:


- if you press the accelerator and
brake pedals at the same time,

- if you force the lever from position P

to another position when the battery
is flat.
To reduce fuel consumption when
stationary for long periods with the
engine running (traffic jam...), position
the gear lever at N
and apply the
parking brake, unless it is programmed
in automatic mode.

211Driving
System which keeps your vehicle immobilised
temporarily (approximately 2 seconds) when
starting on a gradient, the time it takes to
move your foot from the brake pedal to the
accelerator pedal.
This function is only active when:


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

- when certain conditions of gradient are met,

- with the driver’s door closed.
The hill star t assist function cannot be
deactivated.





Hill start assist


On an ascending slope, with the vehicle
stationar y, the vehicle is held for a brief
moment when you release the brake pedal:



- if you are in first gear or neutral with a
manual gearbox,

- if you are in position A
or M
with the
electronic gearbox system,

- if you are in position D
or M
with an
automatic gearbox.


Operation

Operating fault

If a fault occurs with the system, these warning
lamps come on. Contact a CITROËN dealer
or a qualified workshop to have the system
checked.
Do not leave the vehicle while it is
being held in the hill star t assist phase.
If you need to leave the vehicle while
the engine is running, apply the parking
brake manually then ensure that the
parking brake warning lamp is on (not
flashing) in the instrument panel.

On a descending slope, with the vehicle
stationar y and reverse gear engaged, the
vehicle is held for a brief moment when you
release the brake pedal.

Stop & Start
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.
Per fect for urban use, the Stop & Start system reduces fuel consumption and exhaust emissions as well as the noise level when stationary.


Operation


Going into engine STOP mode

With the electronic gearbox system,
for your comfort during parking
maoeuvres, STOP mode is not
available for a few seconds after
coming out of reverse gear.
STOP mode does not affect the
functionality of the vehicle, such as
braking, power steering, for example.
Never refuel with the engine in STOP
mode; you must switch off the ignition
with the key. The "ECO"
warning lamp comes
on in the instrument panel and the
engine goes into standby:


- with a manual gearbox
, at speeds below
12 mph (20 km/h), when you put the gear
lever into neutral and release the clutch
pedal,

- with the 6-speed electronic gearbox
system
, at a speed below 5 mph (8 km/h),
when you press the brake pedal or put the
gear lever into position N
.
If your vehicle is fitted with the
system, a time counter calculates
the sum of the periods in STOP
mode during a journey. It resets
itself to zero every time the ignition
is switched on with the key. STOP mode is not invoked when:


- the driver's door is open,

- the driver's seat belt is not fastened,

- the vehicle has not exceeded 6 mph
(10 km/h) since the last engine star t
using the key,

- the electric parking brake is applied or
being applied,

- the engine is needed to maintain a
comfor table temperature in the passenger
compartment,

- demisting is active,

- some special conditions (battery charge,
engine temperature, braking assistance,
ambient temperature...) where the engine is
needed to assure control of a system.


Special cases: STOP mode
unavailable
In this case, the "ECO"
warning lamp
flashes for a few seconds, then goes
off.

This operation is per fectly normal.

213Driving

Going into engine START mode

The "ECO"
warning lamp goes off
and the engine star ts:


- with a manual gearbox
, when you fully

depress the clutch pedal,

- with the 6-speed electronic gearbox
system
:


●
gear lever in position A
or M
, when you
release the brake pedal,

●
or gear lever in position N
and the brake
pedal released, when you move the gear
lever to position A
or M
,

●
or when you engage reverse gear.




Special cases: START invoked
automatically
If the system has been deactivated
in STOP mode, the engine restarts
immediately. With a manual gearbox in STOP
mode, if a gear is engaged without
fully depressing the clutch pedal, a
warning lamp comes on or a message
is displayed asking you to depress the
clutch pedal to restar t the engine.
At any time, press the "ECO OFF"
switch to
deactivate the system.
This is confirmed by the switch warning lamp
coming on accompanied by a message on the
screen.

Deactivation

In this case the "ECO"
warning lamp
flashes for few seconds, then goes
off.

This operation is per fectly normal.
For safety reasons or to ensure smooth
operation, START mode is invoked
automatically when:


- you open the driver's door,

- you unfasten the driver's seat belt,

- the speed of the vehicle exceeds 15 mph
(25 km/h) with a manual gearbox or
7 mph (11 km/h) with the 6 -speed
electronic gearbox system,

- the electric parking brake is being applied,

- some special conditions (battery charge,
engine temperature, braking assistance,
ambient temperature...) where the engine is
needed to assure control of a system.

The system is reactivated automatically
at every new star t using the key.


Reactivation

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. In the event of a malfunction with the system,
the "ECO OFF"
switch warning lamp flashes,
then comes on continuously.
have it checked by a CITROËN dealer or a
qualified workshop.
In the event of a fault in STOP mode, the
vehicle may stall. It is then necessary to switch
off the ignition and star t the engine again using
the key.


Operating fault
Maintenance

Before doing anything under the
bonnet, deactivate the Stop & Start
system to avoid any risk of injury
resulting from automatic operation of
START mode.
The Stop & Star t system makes use
of advanced technology. All work on
this type of battery must be done only
by a CITROËN dealer or a qualified
workshop. Press the "ECO OFF"
switch again.
The system is active again; this is confirmed
by the switch warning lamp going off and a
message in the instrument panel.

Blind spot sensors


This driving assistance system warns the driver
of the presence of another vehicle in the blind
spot angle of their vehicle (areas masked from
the driver's field of vision), as soon as this
presents a potential danger.

Operation


This system is designed to improve safety when driving and is in no circumstances a
substitute for the use of the interior rear view mirror and door mirrors. It is the driver's
responsibility to constantly check the traffic, to asses the distances and relative speeds of
other vehicles and to predict their movements before deciding whether to change lane.
The blind spot sensor system can never replace the vigilance and responsibility of the
driver.



)
On switching on the ignition, or engine
running, press this button to activate the
function; the warning lamp comes on.
Sensors fitted in the front and rear bumpers
monitor the blind spots. A warning lamp appears in the door mirror on
the side in question:


- immediately, when being overtaken,

- after a delay of about one second, when
over taking a vehicle slowly.
