HILL StA rt ASSIS t
This system (also called HHC - Hill Holder
Control), linked to the dynamic stability
control system, makes hill starts easier and
is activated in the following conditions:
-

the vehicle must be stationary
, engine
running, foot on the brake,
-

the gradient of the road must be steeper

than 5%,
-

uphill, the gearbox must be in neutral or

in a gear other than reverse,
-

downhill, reverse gear must be engaged.
The Hill Start

Assist system is a driving
aid. It is not an automatic vehicle parking
function or an automatic parking brake.Operation
With the brake pedal and clutch pedal
pressed, from the time you release the brake
pedal, without using the parking brake, you
have approximately 2 seconds to move off
before the vehicle starts to roll back.
During the moving off phase, the function
is deactivated automatically, gradually
releasing the braking pressure. During
this phase, the characteristic noise of
mechanical release of the brakes may be
heard, indicating the imminent movement of
the vehicle.
Operating fault
If a malfunction of the system
occurs, this warning lamp comes
on accompanied by an audible
signal and confirmed by a message
in the screen. Have the system checked by a
CITROËN dealer or a qualified workshop. Hill start assist is deactivated in the following
situations:
-

when the clutch pedal is released,
-


when the parking brake is applied,
-


when the engine is switched of
f,
-

when the engine stalls.

Switching off
This system cannot be deactivated by
the
driver.
dynamic stability control
( d S c )
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.
With the DSC system, maintain course
without trying to countersteer.
Operation
The DSC system is activated automatically
each time the vehicle is started. Operating fault
Illumination of this warning lamp,
accompanied by an audible signal
and confirmed by a message
in the instrument panel screen,
indicates a fault with the DSC system.
Have it checked by a CITROËN dealer or a
qualified workshop. Operation
This system is activated automatically every
time the vehicle is started.
In the event of a problem of adhesion or
trajectory, this system comes into play.
Switching off
In exceptional conditions (starting a vehicle
which is bogged down, stuck in snow,
on soft ground...), it may be advisable to
deactivate the ASR system, so that the
wheels can spin freely and regain grip.
-

Press this button, located in the

middle of the dashboard, to deactivate
the
system.
Anti-slip regulation (ASr)
Anti-slip regulation (also known as traction
control) optimises traction, avoiding wheel
spin by acting on the brakes of the driving
wheels and the engine.
If the button's warning lamp comes
on, accompanied by a message in the
instrument panel screen, this indicates that
the ASR system is deactivated.
It comes into operation in the
event of a grip or trajectory
problem.
This is indicated by flashing of this warning
lamp in the instrument panel.

Hill descent control
System that provides assistance when
descending on surfaces with poor grip (mud,
gravel...) or on a steep gradient.
This system reduces the risk of slip or loss
of control of the vehicle while descending
a hill.
It keeps the vehicle at a steady speed during
a descent by acting independently and with
varying force on each of the brakes. Switching off
Press this button, located in the middle of the
dashboard, to deactivate the system; the indicator
lamp in the button goes off.
Above 30 mph (50 km/h), the system is completely
deactivated; the indicator lamp in the button goes off.
Operating fault
If a fault occurs with the hill
descent control system, this
warning lamp comes on.
Have the system checked by a CITROËN
dealer or a qualified workshop.
Switching on
On starting the vehicle, the system is
deactivated.
With the speed below 18 mph (30 km/h)
press this button, located in the middle of
the dashboard, to activate the system; the
indicator lamp in the button comes on.
Once the vehicle starts its descent, you can
release the accelerator and brake pedals;
the indicator lamp in the button flashes.
The brake lamps come on automatically
when the system is brought into operation.
If the speed of the vehicle exceeds 18

mph
(30 km/h), the system is automatically
deactivated, but the indicator lamp in the
button stays on.
The system reactivates automatically as
soon as the speed of the vehicle drops
below 18 mph (30 km/h).
For the system to operate, the slope
must be steeper than 8%.
Do not use the system with the gearbox in
neutral.
Engage an appropriate gear for the speed of
the vehicle, to avoid the engine stalling.
You can press the accelerator or brake
pedal at any time. The system may not be available if the
brakes overheat. Wait a few minutes
for them to cool down before trying again.

driving advice
distribution of loads: distribute the load in
the trailer so that the heaviest objects are as
close as possible to the axle and the nose
weight is close to the maximum authorised
without, however, exceeding it.
c

ooling: towing a trailer on a slope
increases the coolant temperature.
As the fan is electrically controlled, its
cooling capacity is not dependent on the
engine speed.
On the contrary, use a high gear to lower the
engine speed and reduce your speed.
In all cases, pay attention to the coolant
temperature.
tyres:

check the tyre pressures of the
towing vehicle and of the trailer, observing
the recommended pressures.
Fitting a towbar
We recommend the use of genuine
CITROËN towbars and their harnesses,
which have been tested and approved from
the design stage of your vehicle and that
the fitting of this equipment is entrusted to
a
CITROËN dealer.
These genuine towbars are compatible with
the operation of the rear parking sensors
and the reversing camera, if fitted to your
vehicle.
If this equipment is not fitted by a CITROËN
dealer, it must be fitted in line with the
manufacturer's instructions.
Good practice
If the coolant temperature
warning lamp comes on, stop the
vehicle and switch off the engine
as soon as possible.
Refer to the "Checks - Levels and
checks" section.
Brakes: towing increases the braking
distance. Drive at a moderate speed,
change down early and brake gradually. Side wind: sensitivity to side wind is
increased. Drive smoothly and at a
moderate speed. ABS: the system only controls the vehicle,
not the trailer.
r

ear parking sensors: the system is
deactivated while the vehicle is towing with a
genuine CITROËN towbar fitted.
Refer to the "Technical data -
Identification markings" section.

Manual gearbox
Have the level checked in accordance with
the manufacturer's servicing schedule.
Good practice
In order to avoid damaging the
electrical units, we strongly advise you
not to use high pressure washing to clean
the engine compartment.
After washing the vehicle dampness, or in
winter, ice may form on the brake discs and
pads: braking efficiency may be reduced.
Make some light brake applications to dry
and de-ice the brakes. Only use products recommended by
CITROËN or products of equivalent quality
and specification.
In order to optimise the operation of units as
important as the braking system, CITROËN
selects and offers specific products.
diesel fuel filter
The Diesel fuel filter is located under the
bonnet, close to the brake fluid reservoir.
If this warning lamp comes on, the
filter must be bled to remove water.
Y

ou can also bleed the fuel filter
regularly, every time the engine oil
is changed.
Bleeding water from the filter
-

Connect a transparent pipe to the head

of the bleed screw 1 .
-

Place the other end of the transparent

pipe in a recipient.
-

Slacken the bleed screw
2. HDi engines uses advanced
technology. All work must be done by
personnel that have had special training,
which can be ensured by going to a
CITROËN dealer or a qualified workshop. -
