TYRE UNDER-INFLATION
DETECTION
System which automatically and continu-
ously checks the pressure of the tyres
while driving.
Sensors fi tted in each valve trigger a
warning in the event of problem (speed
above 12 mph (20 km/h)).
This warning lamp is displayed
on the instrument panel and/or a
message appears in the screen,
accompanied by an audible signal,
to identify the wheel concerned.

Under-infl ated tyre
The STOP
warning lamp
comes on and/or this warn-
ing lamp is displayed on the
instrument panel, accompa-
nied by an audible signal and
a message in the screen iden-
tifying the wheel concerned.


)
Stop as soon as it is safe to do so,
avoiding any sudden movement of
the steering wheel and the brakes.

)
Repair or change the damaged
wheel (punctured or very defl ated
tyre), and have the tyre pressure
checked as soon as possible.

Puncture

Sensor(s) not detected or faulty
A message appears in the screen, ac-
companied by an audible signal, to
identify the wheel or wheels which are
not detected or to indicate a malfunc-
tion in the system.
Contact a CITROËN dealer or a quali-
fi ed workshop to replace the faulty
sensor(s).
This message is also displayed
when one of the wheels is away
from the vehicle (being repaired)
or when one or more wheels
without a sensor are fi tted.
If your vehicle is equipped with
a spare wheel, this is not fi tted
with a sensor. All repairs and changing of tyres
on a wheel fi tted with this sys-
tem must be carried out by a
CITROËN dealer or a qualifi ed
workshop.
If, when changing a tyre, you
install a wheel which is not de-
tected by your vehicle (example:
fi tting of snow tyres), you must
have the system reinitialised by
a CITROËN dealer or a qualifi ed
workshop.
The tyre under-infl ation detec-
tion system is an aid to driving
which does not replace the need
for the driver to be vigilant or to
drive responsibly. This system does not avoid the
need to have the tyre pressures
checked regularly (refer to the
"Identifi cation markings" sec-
tion) to ensure that the optimum
dynamic performance of the ve-
hicle is maintained and prevent
premature wear of the tyres, par-
ticularly in arduous driving condi-
tions (heavy load, high speed).
The tyre pressures must be
checked cold, at least once a
month. Remember to check the
pressure of the spare wheel.
The tyre under-infl ation detec-
tion system may experience
temporary interference due to
electro-magnetic emissions on a
frequency close to that used by
the system.


)
Check the tyre pressures as soon
as possible.
This check must be carried out when
the tyres are cold.

TRAJECTORY CONTROL
SYSTEMS (ESP)

Anti-slip regulation (ASR) and
electronic stability control
(ESC)

The anti-slip regulation (also known as
traction control) optimises traction to pre-
vent skidding of the wheels, by acting on
the brakes of the driving wheels and on
the engine.
The electronic stability control 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.

Activation
These systems are activated automati-
cally 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 instru-
ment panel.








Intelligent traction control
system ("Snow motion")
Your vehicle has a system to help driving
on snow: intelligent traction control.
This system detects situations of diffi -
cult surface adhesion that could make it
diffi cult to move off or make progress on
deep fresh snow or compacted snow.
In these situations, the intelligent trac-
tion control
limits the amount of wheel
slip to provide the best traction and tra-
jectory control for your vehicle.

Deactivation
In exceptional conditions (starting a ve-
hicle which is bogged down, stuck in
snow, on soft ground...), if you are unable
to make progress, it may be advisable to
temporarily deactivate these systems, so
that the wheels can spin freely and allow
the vehicle to move.


)
Press the "ESP OFF"
button, located
near the steering wheel.

If this warning lamp comes on in the in-
strument panel and the indicator lamp
in the button comes on, this indicates
that these systems are deactivated.

The use of snow tyres is strongly
recommended on surfaces offer-
ing low levels of adhesion.

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

Moving off



)
With your foot on the brake, select
position P
or N
.

)
Start the engine.
If this procedure is not followed, there
is an audible signal, accompanied by a
message in the multifunction screen.


)
With the engine running, press the
brake pedal.

)
Release the parking brake, unless it
is programmed to automatic mode.

)
Select position R
, D
or M
,

)
Gradually release the brake pedal.
The vehicle moves off immediately.

If position N
is engaged inadver-
tently while driving, allow the en-
gine to return to idle then engage
position D
to accelerate.

When the engine is running at
idle, with the brakes released,
if position R
, D
or M
is selected,
the vehicle moves even without
the accelerator being pressed.
When the engine is running,
never leave children in the ve-
hicle without supervision.
When carrying out maintenance
with the engine running, apply
the parking brake and select po-
sition P
.



Automatic operation



)
Select position D
for automatic

changing of the six gears.
The gearbox then operates in auto-
adaptive mode, without any intervention
on the part of the driver. It continuously
selects the most suitable gear accord-
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.
Never select positions P
or R

unless the vehicle is completely
stationary.



Sport and snow programmes

for details of the level checking
interval for this component.






















Electric parking brake


This system does not require any
routine servicing. However, in
the event of a problem, have the
system checked by a CITROËN
dealer or a qualifi ed workshop.

For more information, see "Driving - Electric parking brake - § Operating faults".
















Brake pads

Brake disc wear

If a loss of effectiveness of this
system is noticed, the parking
brake must be checked, even
between two services.
Checking this system must be done by
a CITROËN dealer or a qualifi ed work-
shop.

















Only use products recommended
by CITROËN or products of equiv-
alent quality and specifi cation.

In order to optimise the opera-
tion of units as important as
the braking system, CITROËN
selects and offers very specifi c
products.
To avoid damaging the electrical
units, the use of a high pressure
washer in the engine compart-
ment is strictly prohibited
.



Manual parking brake

For information on checking
brake disc wear, contact a
CITROËN dealer or a quali-
fi ed workshop. Brake wear depends on the
style of driving, particularly in
the case of vehicles 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 system, a
drop in the brake fl uid level indicates
that the brake pads are worn.

PRACTICAL INFORMATION
207





TOWING A TRAILER,
A CARAVAN, ETC.
We recommend the use of genu-
ine CITROËN towbars and their
harnesses that have been tested
and approved from the design
stage of your vehicle, and that
the fi tting of the towbar is en-
trusted to a CITROËN dealer or
a qualifi ed workshop.
If the towbar is not fi tted by a
CITROËN dealer, it is impera-
tive that it is fi tted in accordance
with the vehicle manufacturer's
instructions. The rear parking sensors will
be deactivated automatically if
a genuine CITROËN towbar is
used.

Towbar suitable for the attachment of a
trailer or caravan 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. Driving with a trailer places greater de-
mands on the towing vehicle and the
driver must take particular care.


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

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, reduce
your speed. The maximum towed load on a long in-
cline depends on the gradient and the
ambient temperature.
In all cases, keep a check on the coolant
temperature.


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


Braking
Towing a trailer increases the braking
distance.
To avoid overheating of the brakes on a
long mountain type of descent, the use
of engine braking is recommended.

Tyres


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


Lighting


)
Check the electrical lighting and sig-
nalling on the trailer.
