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.

DRIVING
In the event of a steep descent or
under excessive acceleration, the
speed limiter (which does not act
on the brakes) may not be able to
prevent the vehicle from exceeding
the programmed speed.
Use of a fl oor mat other than that
recommended by CITROËN may
affect the normal operation of the
accelerator pedal and hamper the
operation of the speed limiter.
Floor mats approved by CITROËN
are fi tted with a 3rd fi xing located in
the pedal area to avoid any risk of
interference with the pedals.

Suspension / Resumption



)
Press on button 3
.
This action causes the information
"PAUSE"
to appear in zone A
of the
instrument panel.
This action does not cancel the
memorised maximum speed which
remains displayed in zone A
of the
instrument panel.


Overriding the programmed
speed
The accelerator pedal has an end-
of-travel switch. In order to exceed
the memorised maximum speed at
any time, you can press the pedal
all the way down. While the speed
is being exceeded, the speed dis-
played in zone A
will fl ash. You have
only to release the accelerator pedal
to return below the maximum speed,
to restore the function.
The speed will also fl ash if the speed
limiter is not able to prevent the vehi-
cle from exceeding the programmed
speed (e.g. on a steep descent or
under excessive acceleration).
To reactivate the speed limiter, re-
lease the accelerator to slow to a
speed lower than the programmed
speed.


Return to normal driving



)
Either press on button 5
.

)
Or select the speed limiter func-
tion.

)
Or stop the engine.



Operating fault

If there is a fault, a message is
displayed accompanied by an au-
dible signal and illumination of the
SERVICE
warning lamp.
Have it checked by a CITROËN
dealer or a qualifi ed workshop.

CHECKS





















Brake pads

Brake wear depends on
the style of driving, par-
ticularly in the case of ve-
hicles used in town, over
short distances. It may be
necessary to have the condition of
the brakes checked, even between
vehicle services.
Unless there is a leak in the circuit, a
drop in the brake fl uid level indicates
that the brake pads are worn.







Manual gearbox

The gearbox does not re-
quire any maintenance (no
oil change).






Automatic gearbox

The gearbox does not re-
quire any maintenance (no
oil change).

Brake disc wear

For information on checking
brake disc wear, contact a
CITROËN dealer or a quali-
fi ed workshop.


Parking brake

If a loss of effectiveness
of this system is noticed,
the parking brake must be
checked, even between
two services.
This system must be checked by a
CITROËN dealer.
Only use products recom-
mended by CITROËN or
products of equivalent quality
and specifi cations.
Do not use a dry cloth with an abra-
sive product for the maintenance of
aluminium parts; use a sponge and
soapy water.
In order to optimise the operation
of units as important as the braking
system, CITROËN selects and of-
fers very specifi c products.
To avoid damaging the electrical
units, the use of a high pressure
washer in the engine compartment
is strictly prohibited
. Refer to the servicing booklet for the
details of the level checking interval
for this component.
Refer to the servicing booklet for de-
tails of the level checking interval for
this component.

PRACTICAL INFORMATION
TOWING A TRAILER

Towbar suitable for the attachment
of a trailer or installation of a bicycle
carrier, with additional lighting and
signalling.

Your vehicle is primarily designed
for transporting people and luggage,
but it may also be used for towing a
trailer.

If the towbar is not fi tted by a
CITROËN dealer, it is imperative
that it is fi tted in accordance with
the vehicle manufacturer's instructions.


Driving advice


Distribution of loads


)
Distribute the load in the trailer
so that the heaviest items are as
close as possible to the axle and
the nose weight approaches the
maximum permitted without ex-
ceeding it.
Air density decreases with altitude,
thus reducing engine performance.
Above 1 000 metres, the maximum
towed load must be reduced by 10 %
for every 1 000 metres of altitude.

Side wind


)
Take into account the increased
sensitivity to side wind.


Cooling
Towing a trailer on a slope increases
the temperature of the coolant.
As the fan is electrically controlled,
its cooling capacity is not dependent
on the engine speed.


)
To lower the engine speed, re-
duce your speed. The maximum towed load on a long
incline depends on the gradient and
the ambient temperature.
In all cases, keep a check on the
coolant temperature.

Braking
Towing a trailer increases the brak-
ing distance.
To avoid overheating of the brakes
on a long mountain type of descent,
the use of engine braking is recom-
mended.

Tyres


)
Check the tyre pressures of the
towing vehicle and of the trailer,
observing the recommended
pressures.


Lighting


)
Check the electrical lighting and
signalling on the trailer.


The rear parking sensors will be
deactivated automatically if a gen-
uine CITROËN towbar is used.


)
If the warning lamp and
the STOP
warning lamp
come on, stop the vehicle
and switch off the engine
as soon as possible.


We recommend the use of genuine
CITROËN towbars and their har-
nesses that have been tested and
approved from the design stage of
your vehicle, and that the fi tting of the
towbar is entrusted to a CITROËN
dealer or a qualifi ed workshop.

Driving with a trailer places great-
er demands on the towing vehicle
and the driver must take particular
care.

Refer to the "Technical Data" section
for details of the weights and towed
loads which apply to your vehicle.
