SAFETY
TRAJECTORY CONTROL
SYSTEMS

Anti-slip regulation (ASR)
and electronic stability
programme (ESP)

Activation
These systems are activated auto-
matically each time the vehicle is
started.
They come into operation in the event
of a grip or trajectory problem.
This is indicated by fl ashing
of this warning lamp in the
instrument panel.


Deactivation
In exceptional conditions (starting a
vehicle which is bogged down, stuck
in snow, on soft ground...), it may be
advisable to deactivate the ASR and
ESP systems, so that the wheels
can move freely and regain grip.


)
Press the "ESP OFF"
button, lo-
cated in the middle of the dash-
board.

If this warning lamp comes on in
the instrument panel and the in-
dicator lamp in the button comes
on, this indicates that the ASR and
ESP systems are deactivated.
Your vehicle has a system to im-
prove traction on snow: intelligent
traction control
.
This system detects situations of low
adhesion that might make moving off
and progress diffi cult on deep fresh
snow or compacted snow .
In these situations the intelligent
traction control
system regulates
the amount of wheel slip to optimise
the traction and trajectory control of
your vehicle.
The anti-slip regulation (also known
as Traction Control) optimises trac-
tion to prevent skidding of the wheels,
by acting on the brakes of the driving
wheels and on the engine.
The electronic stability programme acts
on the brake of one or more wheels
and on the engine to keep the vehicle
on the trajectory required by the driver,
within the limits of the laws of physics.








Intelligent traction control
system ("Snow motion") For vehicles with Hydractive III +
suspension, manual adjustment of
ground clearance to the intermediate
position improves further the ability
to make progress in deep snow (see
the relevant paragraph).
The use of snow tyres is strongly
recommended on surfaces with low
adhesion.

It is recommended that these systems
be reactivated as soon as possible.

brake. It is obtained by means of a
long pull
on control lever A
, until
you see the message "Max appli-
cation of the parking brake" and a
beep is heard.

Maximum application is essen-
tial:



- in the case of a vehicle towing
a caravan or a trailer, if the au-
tomatic functions are activated
but you are applying the parking
brake manually,

- when the effective gradient you
are parked on is variable (e.g. on
a ferry, in a lorry, during towing).


- In the case of towing, a loaded
vehicle or parking on a gradient,
turn the front wheels towards the
pavement and engage a gear
when you park.

- After a maximum application, the
release time will be longer.



Particular situations

In certain situations (starting the en-
gine...), the parking brake can auto-
matically alter its level of application.
This is normal operation.
To advance your vehicle a few cen-
timetres without starting the engine,
but with the ignition on, press on the
brake pedal and release the parking
brake by pushing
then releasing

control lever A
.
The full release of the parking brake
is confi rmed by the warning lamp P

in the control lever and the warning
lamp in the instrument panel going
off and the display of a message
"parking brake off" in the instrument
panel screen.
If the parking brake malfunctions
while applied
or if the battery is fl at,
an emergency release is still pos-
sible.
To ensure correct operation of the
parking brake and therefore your
safety, the number of successive
application/release operations is
limited to eight.
If this number is exceeded, you are
warned by the message "Parking
brake faulty" and a warning lamp
fl ashes.

Dynamic emergency braking

In the event of a failure of the ve-
hicle’s main braking system or in
an exceptional situation (e.g. driver
taken ill, under instruction, etc) pull
and hold control lever A
to stop the
vehicle.
The electronic stability programme
(ESP) provides stability during dy-
namic emergency braking.
If there is a fault with the dynamic
emergency braking, one of the fol-
lowing messages will be displayed
in the instrument panel screen:


- "Parking brake faulty".

- "Parking brake control faulty". If a failure of the ESP sys-
tem is signalled by the light-
ing of this warning lamp,
then braking stability is not
guaranteed. In this event, stability
must be assured by the driver by
repeating alternate "pull release" ac-
tions on control lever A
.

The dynamic emergency brak-
ing should only be used in ex-
ceptional circumstances.

Emergency parking brake
release

In the event of the electric parking
brake failing to release, an emergen-
cy device can be used to release the
parking brake manually, provided that
it is possible to immobilise the vehicle
while the procedure is carried out.


)
If you can start the vehicle: with
the engine running, immobilise
the vehicle by applying the foot
brake while the operation is be-
ing carried out.

)
If you are unable to start the ve-
hicle (fl at battery for example):
do not use this device and con-
tact a CITROËN dealer or a
qualifi ed workshop. However, if
you are obliged to proceed, fi rst
immobilise your vehicle securely
and then follow the instructions
below. If the vehicle cannot be im-
mobilised, do not operate
the emergency release. Your ve-
hicle may run away if on a slope.

GEAR EFFICIENCY
INDICATOR *

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

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 engaging the in-
termediate gears.
The gear engagement recommen-
dations must not be considered
compulsory. In fact, the confi gu-
ration of the road, the amount of
traffi c and safety remain determin-
ing factors when choosing the best
gear. Therefore, the driver remains
responsible for deciding whether or
not to follow the advice given by the
system.
This function cannot be deactivated.

*
According to engine.
Example:


- You are in third gear.

- You press the accelerator pedal
moderately.

- The system may suggest that
you engage a higher gear, if ap-
propriate.
The information appears in the in-
strument panel in the form of an ar-
row accompanied by the suggested
gear.

In the case of driving which
makes particular demands on
the performance of the engine
(fi rm pressure on the accelerator
pedal, for example, when overtak-
ing...), the system will not recom-
mend a gear change.
The system never suggests:


- engaging fi rst gear,

- engaging reverse gear,

- engaging a lower gear.
