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:
-
b
efore a long journey,
-

a
t each change of season,
-

a
fter a long period out of use.
Do not forget the spare wheel and the tyres on
any trailer or caravan. Have your vehicle ser viced regularly (engine
oil, oil filter, air filter, cabin filter, etc.) and
obser ve the schedule of operations in the
manufacturer's service schedule.
With a
BlueHDi Diesel engine, if the SCR
system is faulty, your vehicle becomes
polluting. Visit a CITROËN dealer or
a qualified workshop as soon as possible to
bring your vehicle's nitrogen oxide emissions
back in line with the regulations.
When filling the tank, do not continue after the
3rd cut-off of the nozzle to avoid over flow.
At the wheel of your new vehicle, it is only
after the first 1,900
miles (3,000 kilometres)
that you will see the fuel consumption settle
down to a
consistent average.
At the end of winter, remove snow tyres and
refit your summer tyres. Limit the loads carried in the vehicle and
reduce wind resistance (roof bars, roof rack,
bicycle carrier, trailer, etc.). Preferably, use a
roof box.
Remove roof bars and roof racks after use.
