CITROEN DS5 Owner's Handbook Manual page 28

Limit the causes of excess
consumption
Spread loads throughout the vehicle; place
the 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 in
preference.
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 aperture,
driver's side.
Carry out this check in particular:
- 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 on
any trailer or caravan.
Have your vehicle serviced regularly (engine
oil, oil filter, air filter...) and observe the
schedule of operations recommended by the
manufacturer.
When refuelling, do not continue after the 3
cut-off of the nozzle to avoid any overflow.
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 settle
down to a consistent average.
