Monitoring
When the engine is
running, this indicates the
temperature of the coolant.
Range
When the engine isrunning , this indicates
the distance which can still be travelled with thefuel remaining in the tankbased on the average
fuel consumption over the
last few miles/kilometres
travelled.

This value may vary following a change
in the style of driving or the relief,resulting in a large variation in the current fuel consumption.
If you only add a few litres, the value
displayed will be incorrect. Therefore,you must fill the tank whenever possible.
Coolant temperature
gauge
If the bar is close to the criticalposition located
on the right, the temperature is too high.
The symbol flashes when your engine is
overheating.
You must stop your vehicle as soon as it is
safe to do so.Wait a few minutes before switching off theengine.
When the range is less than 30 miles (50 km),
dashes are displayed.
Refuel as soon as possible. The display of the range is updated.


Wait for the engine to cool beforetopping up the level. The cooling system is pressurised.
To avoid any risk of scalding, unscrew the cap by two turns to allow thepressure to drop. When the pressure has dropped,remove the cap and top up the level, if necessary.
Contact a CITROËN dealer or aqualified workshop.


When you disconnect the battery, the previous fuel consumption data is lost and the value displayed will be different from that displayed before thebattery was disconnected. The distancedisplayed must be considered anapproximate indication.

Comfort








Vent ilat ion
The air circulating in the passenger compartment
is filtered and originates either from the outside via
the
grille located at the base of the windscreen or from the inside in air recirculation mode.
Air treatment
The incoming air follows various routes
depending on the controls selected by thedriver:
- direct arrival in the passenger compartment (air intake),
- passage through a heating circuit (heating),
- passage through a cooling circuit (air conditioning).
Control panel
The controls of this system are grouped
together on control panel A on the centreconsole.
1.Windscreen demisting-defrosting vents.2.
Front side window demisting-defrosting
vents. 3. Side adjustable air vents.
4.Central adjustable air vents. 5

Automatic operation
)
Set the temperature control dial 1to thetemperature required.)
Place the air flow control dial 2
in the "AUTO"
position.)
Place the air distribution adjustment dial 3in the "AUTO"position.


When the engine is cold, to avoid an excessive distribution of cold air, theventilation will reach its optimum level gradually.
On entering the vehicle, the interior temperature may be much colder (or warmer) than the temperature setting. There is no need to change thetemperature setting in order to reachthe comfor t required rapidly.
The automatic regulation of the air conditioning will operate to correct thetemperature difference as quickly aspossible. In
automatic mode:)when the temperature is set to maximum (Rapid heating), the intake of exterior air is
activated and the air conditioning stops.)when the temperature is set to minimum(Rapid cooling), air recirculation isactivated and the air conditioning operates.

The system controls the air distribution, the flow, the temperature and the air intake to ensure the level of comfort selected and
adequate air circulation in the passenger compartment. No further action on your part is
required.

Practical information
Driving advice
Distribution of loads
)Distribute the load in the trailer so that theheaviest 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 towing load must
be reduced by 10 % of the GTW and so on for every 1 000 metres of altitude.
Refer to the "Technical Data" section for details
of the weights and towing loads which apply to your vehicle.
Side wind
)Take into account the increased sensitivity
to side wind.

Cooling

To w i ng a trailer on a slope increases the
temperature of the coolant.
As the fan is electricall
y controlled, its cooling capacity is not dependent on the engine speed.)
To lower the engine speed, reduce your speed.
The maximum towing load on a long slope
depends on the gradient and the outside
tem
perature.
In all cases, pay attention to the coolant
temperature.
) If this message is displayed, stop your vehicle as soon as it is safe to do so.


Braking

To w i ng a trailer increases the braking distance.


Tyres
)Check the tyre pressures of the towingvehicle and of the trailer, obser ving the recommended pressures.



Lighting
)Check the lighting and signalling on the
trailer.
I
f the message flashes slowly, wait for the engine to cool before topping up the level, if necessary.
If the messa
ge flashes rapidly, contact a CITROËN dealer or a qualified workshop
without delay.

Checks











Bonnet
)Open the right hand front door. )Pull the interior bonnet release lever A ,
located at the bottom of the door aper ture.
Do not open the bonnet in high winds. When the engine is hot, handle theexterior safety catch and the bonnetstay with care (risk of burns).
)
Unclip the stay C
from its housing on the back of the bonnet. )
Fix the stay in the notch to hold the bonnet open.


Closing
)
Take the stay out of the support notch. )
Clip the stay in its housing on the back of
the bonnet.) Lower the bonnet and release it at the endof its travel. )
Pull on the bonnet to check that it is secured correctly.


The location of the interior bonnet releaselever prevents opening of the bonnet while the right hand front door is closed.


Opening
)Push the exterior safety catch B
to the left and raise the bonnet.
This messa
ge appears in the instrument panelscreen if the bonnet is not fully closed.
The cooling fan may star t after switching off the engine: take carewith ar ticles and clothing that mightbecome caught by the fan blades.

Checks
The coolant level should be closeto the "MA X" mark but should never exceed it.

In addition, as the cooling system is pressurised,
wait at least one hour after switching off the engine before carrying out any work.
To a v o i d a ny risk of scalding, unscrew the cap by two turns to allow the pressure to drop.
When the pressure has dropped, remove the
cap and top up the level.

Changing the coolant
The coolant does not have to be changed.


Fluid specifi cation

The coolant must conform to themanufacturer's recommendations. Th
e brake fluid level should be close
to the "MA X" mark. If it is not, check
the brake pad wear.
Brake fluid level
Changing the fl uid
Refer to the ser vicing booklet for details of the
interval for this operation.
Fluid specifi cation
The brake fluid must conform to themanufacturer's recommendations and meet
the DOT3 or DOT4 standard.
The cooling fan may start after switching off the engine: take care with ar ticles and
clothing that might become caught by the
fan blades.
When the engine is warm, the temperature of
the coolant is regulated by the fan.
