Emergency braking


In the event of failure of the elec-
tronic stability control system,
signalled by the illumination of
this warning lamp, braking sta-
bility is then not guaranteed.
In this event, stability must be assured
by the driver by repeating alternate
"pull-release" actions on the control
lever A
.
In the event of a failure of the main
service brake or in an exceptional
situation (e.g. driver taken ill, under
instruction, etc) a continuous pull on
the control lever A
will stop the vehicle.
The electronic stability control provides
stability during emergency braking.
If the emergency braking malfunctions,
the message "Parking brake faulty" will
be displayed.
The emergency braking must
only be used in exceptional cir-
cumstances.










Emergency release

In the event of the electric parking brake
malfunctioning or the battery running
fl at, an emergency manual device can
release the parking brake.


)
Immobilise the vehicle (or keep it sta-
tionary, if the brake pedal is pressed),
with the engine running, by engaging
fi rst gear (manual gearbox), position P

(automatic gearbox) or position M
or R

(6-speed electronic gearbox system).

)
Switch off the engine but leave the
ignition on. If it is not possible to im-
mobilise the vehicle, do not operate
the control and contact a CITROËN
dealer or a qualifi ed workshop without
delay.

)
Fetch the two vehicle blocks B
and
the release device C
, located under
the boot carpet.

)
Immobilise the vehicle by placing
the blocks in front or behind the two
front wheels, opposite to the direc-
tion of the slope.
For safety reasons, after this op-
eration it is essential to contact
a CITROËN dealer or a qualifi ed
workshop without delay to re-
place the protective cover.
Following an emergency unlock-
ing, immobilisation of the vehicle
is no longer assured once the
manual emergency release has
been deployed and the manual
control does not allow the re-
application of your parking brake.
Take no action, either on the
control lever A
, or stopping start-
ing the engine while the release
device is engaged.
Take care not to allow moisture
or dust in the proximity of the
protective cover.

)
Remove the storage box under the
boot carpet for access to the emer-
gency release device.

)
Pierce the protective cover D
on the
tube E
with the release device.

)
Place the release device in the tube.

)
Turn the release device clockwise .

For safety reasons
, it is essential

to continue turning the device until it
reaches its stop. The parking brake
is released.

)
Remove the release device and
store it with the blocks in the toolbox
under the boot carpet.

- The operation of the parking brake re-
initialises when the ignition is switched
off then on again. If the reinitialisation
of the parking brake proves impos-
sible, contact a CITROËN dealer or a
qualifi ed workshop.

- The subsequent time required for ap-
plication may be longer than during
normal operation.

GEAR EFFICIENCY INDICATOR *

System which reduces fuel consump-
tion by advising the driver to change up
on vehicles fi tted with a manual gearbox.

*
According to engine.


Operation

The system intervenes only when driving
economically.
Depending on the driving situation and
your vehicle's equipment, the system may
advise you to skip one or more gears. You
can follow this instruction without engag-
ing the intermediate gears.
The gear engagement recommenda-
tions must not be considered compulsory.
In fact, the confi guration of the road, the
amount of traffi c and safety remain de-
termining factors when choosing the best
gear. Therefore, the driver remains re-
sponsible for deciding whether or not to
follow the advice given by the system.
This function cannot be deactivated.
- You press the accelerator pedal
moderately.
Example:


- You are in third gear.

- The system may suggest that you
engage a higher gear, if appropriate.
The information appears in the instru-
ment panel in the form of an arrow
accompanied by the suggested gear.

In the case of driving which makes
particular demands on the perfor-
mance of the engine (fi rm pres-
sure on the accelerator pedal, for
example, when overtaking...), the
system will not recommend a gear
change.
The system never suggests:


- engaging fi rst gear,

- engaging reverse gear,

- engaging a lower gear.

The gears engaged appear in
succession in the instrument
panel screen.
The gear change requests are only act-
ed on if the engine speed permits.
It is not necessary to release the accel-
erator during gear changes.
When braking or slowing down, the
gearbox changes down automatically
to allow the vehicle to accelerate in the
correct gear.
On sharp acceleration, the gearbox will
not change up unless the driver acts on
the gear lever or the steering mounted
paddles.
Temporary control of gear changing
You can temporarily take over control
of gear changing using the "+"
and "-"

steering mounted paddles: if the engine
speed allows, the request to change
gear is acted on.
This function allows you to anticipate
certain situations such as overtaking a
vehicle or the approach to a corner.
After a few moments without any action
on the control paddles, the gearbox re-
sumes automatic control of the gears.

Never select neutral N
while the
vehicle is moving.
In both cases, you must apply the
parking brake
to immobilise the
vehicle. When immobilising the vehicle,
with the engine running, you must place
the gear lever in neutral

ing to the style of driving, the profi le of
the road and the load in the vehicle.
For maximum acceleration without
touching the lever, press the accelera-
tor pedal down fully (kick down). The
gearbox changes down automatically
or maintains the gear selected until the
maximum engine speed is reached.
On braking, the gearbox changes down
automatically to provide effi cient engine
braking.
If you release the accelerator sharply,
the gearbox will not change to a higher
gear for safety reasons.

Never select position N
while the
vehicle is moving.

gearbox will operate temporarily in au-
tomatic mode.

D
disappears and the gears
engaged appear in succes-
sion in the instrument panel.
If the engine speed is too low
or too high, the gear selected
fl ashes for a few seconds, then the ac-
tual gear engaged is displayed.
It is possible to change from position D

(automatic) to position M
(manual) at
any time.
When the vehicle is stationary or mov-
ing very slowly, the gearbox selects
gear M1
automatically.
The sport and snow programmes do
not operate in manual mode.
Invalid value during manual
operation
This symbol is displayed if a
gear is not engaged correctly
(selector between two posi-
tions).



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 af-
ter 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.


You risk damaging the gearbox:


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

- if you force the lever from po-
sition P
to another position
when the battery is fl at. When the ignition is on, the
lighting of this warning lamp,
accompanied by an audible
signal and a message in the multifunc-
tion screen, indicates a gearbox mal-
function.
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), lo-
cal speed restrictions permitting.
Have it checked by a CITROËN dealer
or a qualifi ed workshop.
This warning lamp may also come on if
a door is opened.

Operating fault

To reduce fuel consumption
when stationary for long periods
with the engine running (traffi c
jam...), position the gear lever
at N
and apply the parking brake,
unless it is programmed in auto-
matic mode.
