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.

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
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.
