Familiarisation
Limit the causes of excess
consumption
Spread loads throughout the vehicle; placethe heaviest items in the bottom of the boot,as close as possible to the rear seats.Limit the loads carried in the vehicle and reduce wind resistance (roof bars, roof rack, bicycle carrier, trailer...). Use a roof box inpreference.Remove roof bars and roof racks after use.

At the end of winter, remove snow tyres and refit your summer tyres.
Observe the recommendations
on maintenance
Check the tyre pressures regularly, when cold, referring to the label in the door aper ture, driver's side.
Carry out this check in par ticular:- before a long journey,- at each change of season,- after a long period out of use. Don't forget the spare wheel and the tyres onany trailer or caravan.
Have your vehicle ser viced regularly (engine oil, oil filter, air filter...) and obser ve the schedule of operations recommended by themanufacturer.


When refuelling, do not continue after the3 rd
cut-off of the nozzle to avoid any over flow.

At the wheel of your new vehicle, it is only after the first 1 800 miles (3 000 kilometres) that you will see the fuel consumption settledown to a consistent average.

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.

Driving











Gear shift indicator * System which reduces fuel consumption by advising the driver to change up on vehicles fitted with a manual gearbox.
Operation
*

According to engine.
The symbol appears in the instrumentpanel suggesting that you change up. In the case of driving which makes par ticular demands on the performanceof the engine (firm pressure on the
accelerator pedal, for example, when over taking...), the system will notrecommend a gear change.The system never suggests: - engaging reverse gear, - engaging a lower gear.
The system intervenes only when driving economically.Depending on the driving situation and your
vehicle's equipment, the system may advise
you to skip one or more gears. You can
follow this instruction without engaging the
intermediate gears.
The gear recommendations should not
be considered compulsory. In fact, theconfiguration of the road, the amount of trafficand safety remain determining factors whenchoosing the best gear. Therefore, the driver remains responsible for deciding whether or not
to follow the advice given by the system.
This function cannot be deactivated.

A.Manufacturer's plate.It is riveted to the right hand middle pillar
and carries the following information:
- manufacturer,
- EU t
ype approval number,
- vehicle identification number (VIN),
- gross vehicle weight,
- gross train weight,
- maximum front axle weight,
- maximum rear axle weight.


The tyre pressures must be checked when the tyres are cold, at least oncea month.


If the tyre pressures are too low, thisincreases fuel consumption.
B.Tyre label. This label is affixed to the the driver's
side middle pillar and carries the followinginformation:


- tyre sizes,

- tyre pressures.
C.Vehicle Identification Number (VIN) under the bonnet.
This number is engraved on the bodyworknear the damper support.
