Demisting the rear screen and/or
mirrors
Pressing this button, with the engine
running, activates the rapid demisting -
defrosting of the rear screen and/or electric
mirrors.
This function switches off:
- when the button is pressed,
- when the engine is switched off,
- automatically to prevent excessive energy consumption. Automatic air conditioning: visibility
programme
The comfort programme (AUTO) may not
be sufficient to quickly demist or defrost the
windows (humidity, several passengers, ice).
In this case, select the visibility programme.
The visibility programme indicator lamp
comes on.
It activates the air conditioning, the air
flow, the defrosting of the rear screen
and provides optimum distribution of
the ventilation to the windscreen and
side windows.
It deactivates the air recirculation.

Good practice
To avoid any risk of poisoning or
asphyxiation, the heater must not be used,
even for short periods, in an enclosed space
such as a garage or workshop which is not
fitted with an exhaust gas extraction system.
Do not park the vehicle on an inflammable
surface (dry grass, dead leaves, paper…),
there is a risk of fire. The temperature near the heater must not
exceed 120 °C. A temperature higher than
this (for example in the case of painting in
an oven) could damage the components of
the electronic circuits.
The heater is supplied by the vehicle's fuel
tank. Ensure that the low fuel warning lamp
is not on.
ADDITIONAL HEATING
Coolant circuit heater
This is an additional and separate system
which heats the Diesel engine cooling
system to make starting easier.
It improves the demisting and defrosting
performance.
Vehicles fitted with an HDi engine may be
fitted with a heater. When the engine is at
idle or the vehicle is stationary, it is normal
to notice a high-pitched whistling noise and
a slight emission of smoke and odour.

Driving safely
ANTI-SLIP REGULATION (ASR) AND DYNAMIC STABILITY CONTROL (DSC)
These systems are linked and complement
the ABS.
The ASR system is very useful for
maintaining optimum drive and avoiding
losses of control of the vehicle on
acceleration.
The system optimises drive to prevent the
wheels skidding, by acting on the brakes of
the drive wheels and on the engine. It also
allows the directional stability of the vehicle
to be improved on acceleration. If there is a variation between the trajectory
followed by the vehicle and that required by
the driver, the DSC system automatically
acts on the engine and the brake of one
or more wheels, in order to put the vehicle
back on course.
Deactivation
In certain exceptional conditions (starting
the vehicle when stuck in mud or snow, or
on loose ground...), it could prove useful
to deactivate the ASR and DSC systems to
make the wheels spin and regain grip.
Operating fault
Good practice
The ASR/DSC systems offer increased
safety during normal driving, but should not
encourage the driver to take risks or to drive
at high speed.
The operation of these systems is assured
only if the recommendations of the
manufacturer regarding the wheels (tyres
and rims), the braking components, the
electronic components and fitting and repair
procedures are observed.
After an impact, have these systems
checked by a CITROËN dealer or a qualified
workshop.
Use the DSC to hold your course without
attempting to countersteer.
Operation
The warning lamp flashes when
operation of the ASR or DSC is
triggered.
They engage again:
- automatically above 30 mph (50 km/h),
- manually by pressing the button again. When a malfunction of the
systems occurs, the warning
lamp and the LED come on,
accompanied by an audible signal
and a message in the screen.
Contact a CITROËN dealer or a qualified
workshop to have the system checked.
The warning lamp may also come on if the
tyres are under-inflated. Check the pressure
of each tyre.
- Press the button, located on the centre console.
- The LED comes on: the ASR and DSC systems no longer
operate.

SAFETY

"GRIP CONTROL"
On snow, mud and sand, this traction
system, associated with the Michelin ® Agilis
51 M+S all terrain tyres, provides a
compromise between safety, adhesion and
traction.
It allows progress to be made in most
conditions of low adhesion. The accelerator pedal must
be pressed sufficiently
so that the engine power
can be used to effectively
manage the various
parameters. Correct use
Your vehicle is designed principally to drive
on tarmac roads but it allows you to drive on
other less passable terrain occasionally.
However, particularly when your vehicle is
heavily laden, it does not permit off-road
activities such as:
- crossing and driving on ground which
could damage the underbody or tear off
components (fuel pipe, fuel cooler, ...),
particularly by obstacles or stones,
- driving on ground with steep gradients and poor grip,
- crossing a stream.

Towing a trailer
ACCESSORIES

For more information about weights,
refer to the administrative documents
(registration document, ...) or to the
"Weights" section of chapter 8.
TOWING A TRAILER, CARAVAN, BOAT, ETC...
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. Cooling

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.
Driving advice
A towed vehicle must free wheel: gearbox in
neutral.

106
Towing a trailer
You should therefore 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 (see the "Identification markings"
section of chapter 8) and of the trailer,
observing the recommended pressures.
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
you entrust the fitting of this equipment to a
CITROËN dealer.
If this equipment is not fitted by a CITROËN
dealer, it is imperative that it is fitted using
the electrical pre-equipment installed at the
rear of the vehicle and in accordance with
the manufacturer's instructions.
In accordance with the general instructions
a reminder of which has been given above,
we draw your attention to the risk associated
with fitting a towbar or electrical accessory
not recommended by CITROËN. Fitting such
equipment could result in the failure of your
vehicle's electronic system. Please obtain
information from the Manufacturer before
fitting this type of equipment.
See the "Levels" section of chapter 6.
Good Practice
In certain cases of particularly arduous
use (towing the maximum load up a steep
slope in high temperatures), the engine
automatically limits its power. In this
case, the air conditioning is automatically
cut off to save engine power.
If the coolant temperature warning
lamp comes on, stop the vehicle
and switch off the engine as soon
as possible. 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/DSC
The ABS or DSC systems only control the
vehicle, not the trailer or caravan.
Rear parking sensors
The parking sensors system does not
function while the vehicle is towing.

Levels
LEVELS
To maintain the reliability of engines and
emission control systems, the use of
additives in engine oil is prohibited. Changing the brake fluid
The brake fluid must be changed at
the intervals stated, according to the
manufacturer's servicing schedule.
Use fluids recommended by the
manufacturer, which fulfil DOT4 standards.
The level must be between the MIN and
MAX marks on the reservoir.
If fluid has to be added frequently, this
indicates a fault which must be checked by a
CITROËN dealer or a qualified workshop as
soon as possible.
Warning lamps
These regular maintenance operations
will keep your vehicle in good running
order. Consult a CITROËN dealer or the
servicing and warranty booklet enclosed in
the handbook pack.
If you have to remove / refit the engine
style cover, handle it with care to avoid
damaging the fixing clips.
Oil level
Check the level regularly and top up
between changes.
Check the level with the vehicle level,
engine cold, using the dipstick. Dipstick
There are two marks on the
dipstick:
A = maximum
If you fill past this mark,
contact a CITROËN
dealer or a qualified
workshop.
B = minimum
Never allow the level to fall
below this mark. Oil change
It is imperative that this is carried out at the
intervals specifi ed and the viscosity grade of
the oil selected must fulfi l the requirements in
accordance with the manufacturer's servicing
schedule. Ask for advice from a CITROËN dealer.
Remove the dipstick before fi lling.
For the 2 litre HDi engine, use the funnel supplied
when fi lling via the sump opening.
Check the level after fi lling (never exceed the max
mark).
Screw the cap back onto the sump before closing
the bonnet.
Viscosity selection
In all cases, the oil selected must meet the
manufacturer's requirements. Checking by means of the warning
lamps in the instrument panel
is described in chapter 2, refer to the
"Instruments and controls" section.
