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.
In extremely severe conditions (deep
snow, mud, ...), when it proves impossible
to move off, it may be useful to temporar-
ily deactivate the ESP/ASR systems to al-
low the wheels to spin freely and so allow
movement of the vehicle.
Deactivation
In exceptional conditions (starting a
vehicle which is bogged down, stuck in
snow, on soft ground...), if you are un-
able to make progress, it may be ad-
visable to temporarily deactivate these
systems, so that the wheels can spin
freely and allow the vehicle to move.
Press the "ESP OFF"
button, locat-
ed near the steering wheel.
If 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 of-
fering low levels of adhesion.
It is recommended that the systems be
reactivated as soon as possible.

DRIVING
157
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 inad-
vertently while driving, allow the
engine to return to idle then en-
gage 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
These two special programmes supple-
ment the automatic operation in very
specifi c conditions of use.
Sport programme "S"
Press button "S"
, after starting the
engine.
The gearbox automatically favours a
dynamic style of driving.
S
appears in the instrument panel.
Snow programme "
"
Press button "
", after starting the
engine.
The gearbox adapts to driving on slip-
pery roads.
This programme improves starting and
drive when traction is poor.
appears in the instrument
panel.
Return to automatic operation
At any time, press the button select-
ed again to quit the programme en-
gaged and return to auto-adaptive
mode.

CHECKS
186
Automatic gearbox
The gearbox does not require
any maintenance (no oil change).
Refer to the maintenance and
warranty guide 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 work-
shop.
Manual parking brake
Only use products recommended
by CITROËN or products of equiva-
lent quality and specifi cation.
In order to optimise the opera-
tion of units as important as
those in the braking system,
CITROËN selects and offers
very specifi c products.
After washing the vehicle, damp-
ness, or in wintry conditions, ice
can form on the brake discs and
pads: braking effi ciency may be
reduced. Make light brake ap-
plications to dry and defrost the
brakes.
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.
Brake pads
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 circuit, a
drop in the brake fl uid level indicates
that the brake pads are worn.
Brake disc wear
For information on checking
brake disc wear, contact a
CITROËN dealer or a quali-
fi ed workshop.
For more information, refer to the "Electric
parking brake - Operating faults" section.
Manual gearbox
The gearbox does not re-
quire any maintenance (no oil
change).
Refer to the maintenance and
warranty guide for the details
of the level checking interval
for this component.
Electronic gearbox
The gearbox does not require
any maintenance (no oil change).
Refer to the maintenance and
warranty guide for details of the
checking interval for this compo-
nent.

PRACTICAL INFORMATION
214
TOWING A TRAILER
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 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.
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.
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 cool-
ant 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.
Refer to the "Technical data" section for
details of the weights and towed loads
which apply to your vehicle.
